Answer:
y=4x-7
Step-by-step explanation:
We know that the y intercept is -7 so we can have y=mx-7
And we can get the slope by using the slope formula (y2-y1)/(x2-x1)=m
(2,1) (0,-7)
x1 y1 x2 y2
(-7-1)/(0-2)
-8/-2 = 4
m=4
So just plug it into the equation to get:
y=4x-7
Answer:
y = 4x - 7
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the t- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 1) and (x₂, y₂ ) = (0, - 7)
m = [tex]\frac{-7-1}{0-2}[/tex] = [tex]\frac{-8}{-2}[/tex] = 4
The line crosses the y- axis at (0, - 7) ⇒ c = - 7
y = 4x - 7 ← equation of line
4x – 4y = 24
y= 7x + 6
A) (-2, 8)
C) (-8,8)
B) (-2, -8)
D) (-8, -8)
Answer:
B) (-2, -8) is the solution for 4x - 4y = 24 and y = 7x + 6
Step-by-step explanation:
4x - 4y = 24
4(-2) - 4(-8) = 24
-8 - (-32) = 24
-8 + 32 = 24
24 = 24
y = 7x + 6
-8 = 7(-2) + 6
-8 = -14 + 6
-8 = -8
Maricella solves for x in the equation 4 x minus 2 (3 x minus 4) + 4 = negative x + 3 (x + 1) + 1. She begins by adding –4 + 4 on the left side of the equation and 1 + 1 on the right side of the equation. Which best explains why Maricella’s strategy is incorrect?
The multiplication that takes place while distributing comes before addition and subtraction in order of operations.
In order to combine like terms on one side of the equation, the inverse operation must be used.
When the problem is worked in the correct order, the numbers that Maricella added are not actually like terms.
Maricella did not combine all three constants on both sides of the equation; she combined only two.
Answer:
The multiplication that takes place while distributing comes before addition and subtraction in order of operations.

Jessica started the school year when she was 64.15 inches tall. She grew 2.87 inches during the school year. How tall, in inches, was Jessica at the end of the year? Show your work.
Answer:
67.02 inches
Step-by-step explanation:
If Jessica started out 64.15 inches and grew 2.87 inches then you know that you must add these together.
64.15 + 2.87 = 67.02
Jessica is 67.07 inches at the end of the school year.

Nadia finds out her favorite horse family population is increasing at a constant rate. The horse family was at 24 in 2011 and is currently at 32 in 2014. Find an equation in point slope form that models the population growth and predict the number of horses in 2020.
Answer:
The equation is p = (8/3) t + 24
In 2020, we will have about 48 horses.
Step-by-step explanation:
In 3 years the family increased by 32 - 24 = 8.
So the constant of proportionality = 8/3.
The required equation is p = (8/3)tx + 24
where p = the population and t is the number of years after 2011.
So in 2020 we can predict that in 2020 the number of horses
= (8/3) * 9 + 24
= 72/3 + 24
= 24 + 24
= 48.

Which expression has a value of 60?
1. 360 divided by 60
2. 3600 divided by 6
3. 3600 divided by 60
4. 3600 divided by 600
3600 divided by 60 is equal to 60. The correct option is 3.
To find the expression that has a value of 40, to evaluate each expression:
1.
360 divided by 60:
Divide 360 by 60 is equal to 6.
So, this is incorrect option.
2.
3600 divided by 6:
Divide 3600 by 6 is equal to 600.
So, this is incorrect option.
3.
3600 divided by 60:
Divide 3600 by 60 is equal to 60.
So, this is correct option.
4.
3600 divided by 600:
Divide 3600 by 600 is equal to 6.
So, this is incorrect option.
Hence, out of the four expressions, the third one, 3600 divided by 60, has a value of 60. So the correct answer is 3 (3600 divided by 60).

Answer:
Step-by-step explanation:
1).
(a). Yes, the graph is linear.
(b). Rate of change is a slope m, m = (60 - 80) / (10 - 0) = - 2

Each exterior angle of a regular polygon is 9°
Calculate the number of sides of the polygon
Answer:
40
Step-by-step explanation:
The sum of the exterior angles of a polygon = 360°
Divide this by the value of 1 exterior angle to find the number of sides n
n = 360 ÷ 9 = 40
Answer:
Required Answer :-Let the number of sides=x
Each angle measures 9°As we know that in a polygon
[tex]{\boxed{\sf Sum\;of\:exterior\:angles=360°}}[/tex]
Substitute the values[tex]{:}\longrightarrow[/tex][tex]\sf 9x=360 [/tex]
[tex]{:}\longrightarrow[/tex][tex]\sf x={\dfrac {360}{9}}[/tex]

Eight bags of chips and four sodas cost $5. Four bags of chips and eight sodas costs
$7. How much does a bag of chips cost? How much does a soda cost?
Answer:
let x be chips and y be sodas
8x + 4y = 5 ---> for the first hint
4x + 8y = 7------> second hint
0.25 cents is how much chips costs
and 0.75 cents is how much sodas costs
Answer: Each bag of chips is $0.25, each soda is $0.75.
(0.25 x 8) + (0.75 x 4) = 5
2 + 3 = 5
(0.25 x 4) + (0.75 x 8) = 7
1 + 6 = 7

ABCD is a square
=> Δ ABD is a isosceles right triangle at A
using pythago theorem, we have:
AB² + AD² = BD²
=> 2AD² = 4
⇔ AD² = 2

through O, draw EF parallel to AD and BC
=> EF is diameter
because EF//AD => EF = AD = √2 (because circle O is inscribed the square ABCD)
=> the area of the circle is [tex]S=\frac{(\sqrt{2})^{2} }{4}.\pi =\frac{\pi }{2}[/tex]
