Given g(x)=-x-4g(x)=−x−4, solve for xx when g(x)=10g(x)=10.
The solution for x in the function when the function g(x) = 10 is 4
How to determine the solution for x in the function?From the question, we have the following equation that can be used in our computation:
g(x)=x-4
To make the equation legible, we need to rewrite it
So, we have the following representation
g(x) = x - 4
Also from the question, we have
g(x) = 10
This means that we calculate x when g(x) = 10
Substitute the known values in the above equation, so, we have the following representation
10 = x - 4
So, we have the following equation
x - 4 = 10
Add 4 to both sides of the equation
So, we have the following representation
x - 4 + 4 = 10 + 4
Evaluate the equation
x = 14
Hence, the solution is 14

iq test scores are normally distributed with a mean of 100 and a standard deviation of 15. an individual's iq score is found to be 90. find the z-score corresponding to this value.
The Z score of the individual with IQ 90 is -0.67.
It is given that the scores are Normally distributed.
The mean given is 100 while the standard deviation is 15.
Let the IQ distribution be X.
Hence X follows a Normal distribution X~N(100, 225)
where
100 = mean
225 = standard deviation
To find the Z score we need to convert the following into the standard normal distribution.
To do that we need to follow
Z = ((x - μ) / σ)
here
μ = mean of the distribution = 100
σ = standard deviation of the distribution = 15
x = 90
Hence the Z score is
Z = (90 - 100) / 15
= -10/15

Jada is working on solving a quadratic equation, as shown here.
p^2−5p=0
p(p−5)=0
p−5=0
p=5
She thinks that her solution is correct because substituting 5 for p in the original expression p^2−5p gives 5^2−5(5), which is 25−25 or 0.
Explain the mistake that Jada made.
Writing only p = 5 is a mistake since p = 0 is also a solution of the quadratic equation
How to find the mistake she made in solving the quadratic equation?
Given the quadratic equation: p² −5p = 0
p² −5p = 0
p(p−5) = 0
p = 0 or p−5=0
p = 0 or p = 5
Jada made mistake in the 3rd step instead of him to break the equation into two parts and then equate them to zero i.e he neglected the part where p = 0 and only make use of p-5 = 0
Since the equation has two solutions, p = 0 and p = -5. Therefore, writing only p = 5 is a mistake because when p = 0 is substituted into p² −5p = 0, it also gives 0

AB (3x + 2) cm AC 11 cm BC (2y + 3) In the diagram, ABC is an equilateral triangle. Find the value of (x+y)
For the given triangle ΔABC the value of (x + y) would be 7 cm.
What is an equilateral triangle?
An equilateral triangle is a triangle with the same length on all three sides. An equilateral triangle is also equiangular in Euclidean geometry; that is, all three internal angles are congruent to each other and are each 60°.
Given data:
Length of AB = (3x + 2) cm.
Length of AC = 11 cm.
Length of BC = (2y + 3) cm.
The property of an equilateral triangle says that all sides of an equilateral triangle are equal.
then we can write,
AB = AC
3x + 2 = 11
3x = 11 - 2
3x = 9
x = 9/3
x = 3 cm
Also, BC = AC
2y + 3 = 11
2y = 11 - 3
2y = 8
y = 8/2
y = 4 cm
So the value of (x + y) = 3 +4
= 7 cm.
Hence, For the given triangle ΔABC the value of (x + y) would be 7 cm.

Two cyclists are 7 miles apart when they begin biking away from each other in opposite directions. The speed of the first cyclist is 12 miles per hour. The speed of the second cyclist is b miles per hour greater than the speed of the first cyclist.
How many miles apart are the cyclists in 45 minutes?
PLEASE HELPPPPPP!!!!!!!!!!!
The distance between two cyclists after 45 minutes as described in the task content is; 7 + 0.75 (12) + 0.75 (b + 12) miles.
Speed, distance and time.It follows from the task content that the distance between the two cyclists after 45 minutes is to be determined from the given parameters.
Given; the speed of the first cyclist is; 12 miles per hour, while the speed of the second cyclist is b miles per hour greater than that of the first.
The speed of the second cyclist is therefore; (b + 12).
On this note, since the distance covered by each cyclist is given by;
Distance = Speed × Time where, Time = 45 minutes = 0.75 hours.
Therefore, the total distance between the two cyclists can be determined from the expression as follows;
7 + 0.75 (12) + 0.75 (b + 12).
Therefore, the distance between the two cyclists as required in the task content is; 7 + 0.75 (12) + 0.75 (b + 12) miles.

Rewrite the equation in Ax+By = C form. Use integers for A, B, and C. y+3=-4(x-6)
Answer:
4x + y = 21
Step-by-step explanation:
1. distribute in the parenthesis first, so the right side of the equation is not -4x+24
Right now the total equation looks like y+3 = -4x+24
2. Now we add the 4x to both sides to cancel it out on the left side, so we're left with:
4x+y+3=24
3. After that we can subtract the 3 from both sides to leave us with:
4x+y=21
Graph the inequality on the axes below −2x+y≥−6
A graph of the inequality (-2x + y ≥ -6) is shown in the image attached below.
What is a graph?A graph simply refers a type of chart that is typically used for the graphical representation of data on both the horizontal and vertical lines of a cartesian coordinate, which are the x-coordinate and y-coordinate.
Next, we would rearrange and simplify the given equation in slope-intercept form as follows:
-2x + y ≥ -6
Adding 2x to both sides of the inequality, we have the following equation:
-2x + y + 2x ≥ -6 + 2x

The function represented by the graph has an equation of f(x) = |x - 3| + 5
How to find the equation of the graph line?From the question, we have the following graph that can be used in our computation:
The graph is an absolute value graph
As a general rule, an absolute value is expressed as
y = |x - h| + k
In this case, the vertex is
Vertex = (h, k)
As a general rule, the vertex of a function is the minimum point on the graph
On the given graph, the minimum point is (3, 5)
This means that
(h, k) = (3, 5)
Substitute the values (h, k) = (3, 5) in the equation y = |x - h| + k
So, we have the following representation
y = |x - 3| + 5

A Pre-K teacher has a total of 4/5 ounces of paint. Th teacher puts 1/30 ounces of paint at each table. If the teacher sets up an equal number of tables in the 2 Pre-K classrooms, how many tables does he set up in each classroom?
Answer:
12 tables per classroom.
Step-by-step explanation:
We will assume that the teacher uses all of the 4/5 oz of paint. We can find how many samples of 1/30 oz are contained in the 4/5 oz by dividing:
(4/5)÷(1/30) = (4/5)*(30/1)
(4/5)*(30/1) = (120/5)
(120/5) = 24 samples of 1/30 oz paint in (4/5) oz total paint.
Each of the 2 Pre-K classrooms have the same number of tables, so we can divide 24 samples by 2 to find the number of tables in each classroom,
*24 samples/2 classrooms) = 12 tables/classroom
