1. -10=xy+z, solve for x please? 2. h-4/j =k, solve for j please?
Answers
Answer:
[tex]x=\frac{-10-z}{y}[/tex]
Step-by-step explanation:
1 Subtract z from both sides.
[tex]-10-z=xy[/tex]
2 Divide both sides by y
[tex]\frac{-10-z}{y} =x[/tex]
3 Switch sides.
[tex]x=\frac{-10-z}{y}[/tex]

Divding both sides by y:
[tex]\displaystyle \frac{-10-z}{y} =x[/tex]
Solving for j:
[tex]\displaystyle h-\frac{4}{j} =k[/tex]
Subtracting h from both sides:
[tex]\displaystyle - \frac{4}{j} =-h+k[/tex]
Multiplying both sides by j,

y = - | x + 3 | + 5 ← in general form, then
vertex = (- 3, 5 )
Suppose A has a coordinate of 8 and AB = 3. What are the possible midpoints of AB?
Answers
Answer:
The possible midpoints of AB are 6.5 and 9.5
Step-by-step explanation:
Given that the coordinates of A is 8
The length of AB = 3
When A is the maximum coordinates of the two coordinates, A and B, we have;
The midpoint of AB = Coordinates of A - 1/2 × Length of AB
The midpoint of AB = 8 - 1/2 × 3 = 8 - 1.5 = 6.5
The midpoint of AB = 6.5
When A is the minimum coordinates of the two coordinates, A and B, we have;
The midpoint of AB = Coordinates of A + 1/2 × Length of AB
The midpoint of AB = 8 + 1/2 × 3 = 8 + 1.5 = 9.5
The midpoint of AB = 9.5
Therefore, the possible midpoints of AB are 6.5 and 9.5.

There are 646,449 people in 68.3 square miles.
a. Calculate the unit rate in terms of people per square mile for the District of Columbia.
Make sure the precision of your answer is reasonable.
Answers
Answer:
9465 people/square mile.
Step-by-step explanation:
If there are 646,449 people in 68.3 square miles for the district of columbia, the unit rate in terms of people per square mile for the District of Columbia will be expressed as shown;
646,449 people = 68.3 square miles
x people = 1 square mile
Cross multiply
646,449 people * 1 square mile = 68.3 square miles * x people
x = 646,449 people * 1 square mile/68.3 square miles
x = 646,449/68.3 square miles
x = 9464.8463 square miles
x ≈ 9465 people/square mile.
Hence the unit rate in terms of people per square mile for the District of Columbia is approximately 9465 people.
What is the slope againnn ?
Answers
Answer:
-1/2
Step-by-step explanation:
To find the slope, pick two points on the line, and use the slope formula
( 1,9) and (5,7)
m = (7-9 )/(5-1)
-2/4
-1/2
Answer:
slope = -1/2
Step-by-step explanation:
Find two points on the line that are easy to read. The easiest points to read are points that lie on grid intersections.
For example, use point (1, 9) and point (3, 8).
slope = rise/run
Rise is the vertical distance between points. Up is positive. Down is negative.
Run is the horizontal distance between points. Right is positive. Left is negative.
You need to go from one point to the other points and note the rise and run.
Start at (1, 9).
Go 1 unit down. That is a rise of -1 since you went down 1 unit.
Now go 2 units right. That is a run of +2 since you went 2 units to the right.
slope = rise/run = -1/2
Answer: slope = -1/2

A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.

The measure of L in triangle LMN is 33°. The measure of M is 79°. What is the measure of N?
Answers
Answer:
N = 68°Step-by-step explanation:
Since ∆LMM is a triangle all it's interior angles sum up to 180°
To find M add up all the angles and N and equate it to 180° to find N
That's
L + M + N = 180
33 + N + 79 = 180
N + 112 = 180
N = 180 - 112
We have the final answer as
N = 68°Hope this helps you

The figure shows SV intersecting plane A at point P, a right angle. Points R, T and U also lie in the plane. Which statements are true based on the figure?
Answers
Based on the figure, the statements that are true are
SV is perpendicular to TPSV is perpendicular to plane Apoint P lies on SV and in plane AThat is, the first, second and fifth statements.
From the image, we will determine the statements that are true based on the figure.
For the first statement - SV is perpendicular to TP
From the figure,
SV is a line intersecting plane A at point P, at right angle. That is, SV is perpendicular to point P. Then, SV is perpendicular to plane A since point P lies on the plane.
Also, P lies on the plane (plane A); then we can infer that TP is parallel to plane A since point T also lie on the plane (plane A).
Since, SV is perpendicular to the plane, then SV is also perpendicular to TP.
∴ The statement (SV is perpendicular to TP) is true
For the second statement - SV is perpendicular to plane A
As stated above, SV is perpendicular to point P. Since point P lies on the plane (plane A), then SV is perpendicular to plane A.
∴ The statement (SV is perpendicular to plane A) is true
For the third statement - points S, P and Q are collinear
Collinear points are points that lie on the same line.
Points S, P and Q are not collinear because, a single line cannot pass through the three points, that is, the points (S, P, and Q) do not lie on a single line.
∴ The statement (points S, P and Q are collinear) is NOT true
(From the image, an example of points that are collinear are points S, P, and V)
For the fourth statement - points R, T, and U are collinear
As explained above, points R, T, and U are not collinear because, a single line cannot pass through the three points, that is, the points (R, T, and U) do not lie on a single line.
∴ The statement (points R, T and U are collinear) is NOT true
NOTE: (The points only lie in the same plane (plane A), that is, they are coplanar)
For the fifth statement - point P lies on SV and in plane A
Since line SV intersects plane A at point P, that means point P lies in plane A. Also point P lies on line SV since it is on the line as shown in the image.
∴ The statement (point P lies on SV and in plane A) is true
For the sixth statement - points U, S, V, and Q are coplanar
Points or lines are said to be coplanar if they lie in the same plane.
Of the given points, only point U lies in plane A. Points S, V, and Q do not lie in the same plane and as well do not lie in the same plane as point U.
∴ The statement (points U, S, V, and Q are coplanar) is NOT true.
(From the image, an example of points that are coplanar are points U,P,R, and T because they lie on the same plane).
Hence, based on the figure, the statements that are true are the first, second and fifth statements. that is
SV is perpendicular to TPSV is perpendicular to plane Apoint P lies on SV and in plane ALearn more here: https://brainly.com/question/17534787
The length of a rectangle is twice it’s with the perimeter of a rectangle is 126 feet.
Answers
Answer:
Length = 42 feet
Width = 21 feet
Step-by-step explanation:
Let the length and width be represented by L and W
L = 2W
Perimeter (P) = 126 feet
2(L + W) = 126
L + W = 126/2 = 63
2W + W = 63
3W = 63
W = 63/3 = 21 feet
L = 2W = 2 × 21 feet = 42 feet

The life expectancy of a monkey is 15 years, an African elephant 35 years, a beaver 5 years, and a grizzly bear 25 years. Write a relation that describes this information. Determine its domain and range.
Answers
Answer:
The domain = 1, 3, 5, 7 and the range = 5, 15, 25, and 35
Step-by-step explanation:
The given parameters are;
The life expectancy of a monkey = 15 years
The life expectancy of an African elephant = 35 years
The life expectancy of a beaver = 5 years
The life expectancy of a grizzly bear = 25 years
Therefore, if the life expectancy of a beaver = X, we have;
The life expectancy of a monkey = 3 × The life expectancy of a beaver = 3·X
The life expectancy of a beaver = X
The life expectancy of an African elephant = 7 × The life expectancy of a beaver = 7·X
The life expectancy of a grizzly bear = 5 × The life expectancy of a beaver = 5·X
Therefore;
The domain = 1, 3, 5, 7 and the range = 5, 15, 25, and 35.
Answer:
Relation = {(Monkey, 15), (African elephant, 35), (Beaver, 5), (Grizzly bear, 25)}

Answers
Answer: 2/23
Step-by-step explanation: Absolute value is a term which is used to indicate the distance of a point or number from the origin of a number line or coordinate system.
Suppose x is a real number. Then the absolute value of x is defined as follows:
For x = 0 or x > 0, | x | = x
For x < 0, | x | = - x
Now, we have to find the absolute value of the given number that means we have to find the distance of from the origin of a number line.
Distance of from the origin is . As distance can never be negative.
Therefore, the absolute value of is 2/23 .
