Answer:
- 21
Step-by-step explanation:
The minimum value occurs at the vertex of the function
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
To obtain this form use the method of completing the square
Given
f(x) = x² - 6x - 12
add/ subtract ( half the coefficient of the x- term)² to x² - 6x
f(x) = x² + 2(- 3)x + 9 - 9 - 12
= (x - 3)² - 21
with vertex = (3, - 21 )
The minimum is the value of k, that is minimum value = - 21

if CE=7x+4 , find the value of X
Answer:
x=5
Step-by-step explanation:
If CE=7x+4, then x+3+(8x-9)=7x+4
x+3+8x-9=7x+4
Combine like terms: 9x-6=7x+4
Isolate x to one side: 2x-6=4
add 6: 2x=10
divide by 2: x=5
check your work;plug x into both equations

===================================================
Work Shown:
c(b) = 5b
h(b) = b+4
h(c(b)) = c(b)+4 ... replace every b with c(b)
h(c(b)) = 5b+4 ... replace c(b) on the right hand side with 5b
For the sake of simplicity, let's call "h(c(b))" as k
k = h(c(b))
k = 5b+4
that way we can use it later in the next section
---------------
a(b) = b^2 + 7
a(k) = k^2 + 7 ... replace b with k
a(k) = (5b+4)^2 + 7 ... plug in k = 5b+4
a(k) = 25b^2+40b+16+7 .... use FOIL rule
a(k) = 25b^2+40b+23
a( h(c(b)) ) = 25b^2+40b+23
In that last step, I replaced k with h(c(b)) so that we get to the original format your teacher wanted.

Suppose you start at the origin, move along the x-axis a distance of 6 units in the positive direction, and then move downward along the z-axis a distance of 3 units. What are the coordinates of your position
Answer:
Coordinates are (x,y,z)= ( 6,0,-3)
Step-by-step explanation:
Because
X = +6units
Y= 0at origin
= -3 units negative because its downwards on the number line
if the area of a rectangle is square meters, then the length is 10 meters and the width is 2 meters
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
To find the area of a rectangle or square, you multiply the length by the height.
The length is 10 meters and the width is 2 meters.
10 times 2 is 20.
The rectangle is 20 square meters.
━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━
The required area of the rectangle is 20 square meters.
Given that,
If a rectangle's area is square meters, then the length is 10 meters and the width is 2 meters.
The rectangle is 4 sided geometric shape whose opposites are equal in length and all angles are about 90°.
Here,
area of the rectangle is given as
Area = length × width
Area = 10 × 2
Area = 20
Thus, the area of the rectangle is 20 square meters.

Answer:
Step-by-step explanation:
rational because 3/4 is rational.
As regards if the fraction 3/8 is a rational or irrational number, the correct answer is that it is a rational number.
Why is 3/8 a rational number?Rational numbers are numbers and fractions that are finite in nature. This means that they do not keep on going with non zero digits.
When converted to a decimal, the number 3/8 is:
= 3/8
= 3 ÷ 8
= 0.375

A farmer was dividing up his one-eighth of an acre of land between his 6 children. Since each child got the same amount of land, what fraction of the acre did each get?
Answer:
1/48
Step-by-step explanation:
A farmer was dividing up his one-eighth of an acre of land between his 6 children.
We are told each child got: the same amount of land. Hence,
1/8 of 1 acre =
1/8 acre of land
Divide 1/8 acre of land by 6 children
1/8 ÷ 6
1/8 × 1/6
= 1/48
Hence, the fraction of the acre of the land that each child got = 1/48

Answer:
[tex]\bold{2\cdot10^9}[/tex]
Step-by-step explanation:
The given expression s are:
[tex]8 \cdot 10^4[/tex] and
[tex]4\cdot10^{-5}[/tex]
To find:
[tex]8 \cdot 10^4[/tex] is how many times as large as [tex]4\cdot10^{-5}[/tex].
Solution:
Let [tex]8 \cdot 10^4[/tex] is [tex]x[/tex] times as large as [tex]4\cdot10^{-5}[/tex].
So, we can say that:
[tex]8 \cdot 10^4[/tex] = [tex]4\cdot10^{-5}[/tex][tex]\times[/tex] [tex]x[/tex]
OR
[tex]x= \dfrac{8\cdot 10^4}{4\cdot 10^{-5}}[/tex]
Let us have a look at the formula for exponents:
[tex]\dfrac{x^p}{x^q} = x^{p-q}[/tex]
Here we have:
[tex]x=10\\p=4\ and\\q=-5[/tex]
Solving the expression using above formula:
[tex]\Rightarrow x= \dfrac{8}{4}\cdot 10^{4-(-5)}} = \bold{2\cdot10^9}[/tex]
So, Let [tex]8 \cdot 10^4[/tex] is [tex]\bold{2\cdot10^9}[/tex] times as large as [tex]4\cdot10^{-5}[/tex]

A movie rental company offers a membership plan that costs $10/month and charges $2 to rent each movie. How many movies can a mentor rent in one month and spend at most $24? Write and solve the linear inquality..... Right Answer Will Be Crowned TYPE SOMETHING OTHER THAN THE ANSWER WILL GET DELETED! CORRECT ANSWER GET 50 POINTS
Answer:
See below
Step-by-step explanation:
linear equation: y=2x+10
x=cost per movie rented
10=$10 for the membership
24=2x+10 (24 being total you want to spend)
subtract 10 from each side
14=2x
divide by 2
7=x
He can rent no more than 7 movies if he want to spend $24 or less in the month

What is the difference between a rational number and anirrational number?
Step-by-step explanation:
I'm sure u could've googled this answer.
Rational numbers refers to a number that can be expressed in a ratio of two integers.
An irrational number is one which can't be written as a ratio of two integers.
Rational numbers are the numbers which are integers and fractions
Irrational numbers are the numbers whose expression as a fraction is not possible
Two complementary angles are in the ratio 7:8. What is the measure of the larger angle?
Answer
48°Step-by-step explanation:
We know that sum of complementary angle adds to 90°
Let the angles be 7x and 8x
First of all, finding the value of x
[tex] \sf{7x + 8x = 90 °}[/tex]
Collect like terms
⇒[tex] \sf{15x = 90 °}[/tex]
Divide both sides of the equation by 15
⇒[tex] \sf{ \frac{15x}{15} = \frac{90}{15} }[/tex]
Calculate
⇒[tex] \sf{x = 6 °}[/tex]
The value of X is 6°
Now, substituting / Replacing the value of x
⇒[tex] \sf{7x = 7 \times 6 = 42}[/tex]
⇒[tex] \sf{8x = 8 \times 6 = 48}[/tex]
The measure of larger angle is 48°
