Given the ordered pairs find the value of r that makes the slope equal to the given value (3 , r) and (7 , 2) m= 1/4
Possibles answers
A) r= -1
B) r= 2
C) r=1
D) r =3
E) r=0
Answer:
C
Step-by-step explanation:
Calculate the slope m using the slope formula, then equate to [tex]\frac{1}{4}[/tex]
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (3, r) and (x₂, y₂ ) = (7, 2)
m = [tex]\frac{2-r}{7-3}[/tex] = [tex]\frac{2-r}{4}[/tex] , then
[tex]\frac{2-r}{4}[/tex] = [tex]\frac{1}{4}[/tex] ( since denominators are both 4, equate the numerators )
2 - r = 1 ( subtract 2 from both sides )
- r = - 1 ( multiply both sides by - 1 )
r = 1 → C

What is the slope of the line that passes through the points (-2, -1)
and (2, -3)? Write your answer in simplest form.
Plug this into the formula y2 - y1 / x2 - x1
-2 = x1, x2 = 2, y1 = -1, y2 = -3
-3 - (-1) / 2 - (-2)
-2 / 4
-1/2
The slope is -1/2.
A wire that is 80 centimeters long is shown below. The wire is cut into two pieces, and each piece is bent and formed into the shape of a square. 80 cm wire Suppose that the side length (in centimeters) of one square is x cm. Express the perimeter of the big square in terms of x. (1 point)
Answer:
The perimeter of the second(big) square = [tex]\mathbf{4 \times \begin {pmatrix} \dfrac{80-x}{4} \end {pmatrix}}[/tex]
Step-by-step explanation:
From the information given:
The length of the piece of the wire = 80 cm
When being cut into two pieces;
the length of the first wire = x
Then the length of the second(big) wire will be = 80 - x
However, when each piece is bent to a square shape
The length of one side of the first square = [tex]\dfrac{x}{4}[/tex]
The length of one side of the second(big) square; [tex]\dfrac{80-x}{4}[/tex]
Area of a square = l² ( where l is the length of the sides)
For the first square
A₁ = [tex](\dfrac{x}{4})^2[/tex]
A₁ = [tex]\dfrac{x^2}{16}[/tex]
The area of the second(big) square is:
A₂ = [tex](\dfrac{80-x}{4})^2[/tex]
A₂ = [tex](\dfrac{(80-x)^2}{4})[/tex]
The perimeter of the first square = [tex]4 \times \dfrac{x}{4}[/tex]
The perimeter of the second(big) square = [tex]\mathbf{4 \times \begin {pmatrix} \dfrac{80-x}{4} \end {pmatrix}}[/tex]

Answer:
b = C - 15

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
[tex]C = 15 + ab[/tex]
Subtract sides 15
[tex]C - 15 = - 15 + 15 + ab[/tex]
[tex]C - 15 = ab[/tex]
Divided sides by a
[tex] \frac{C - 15}{a} = \frac{a \times b}{a} \\ [/tex]

Which of the following does NOT represent the equation y= 2x
Answer:
G
Step-by-step explanation:
In F, the graph goes up by two and only to the side by 1. 2/1 simplifies to 2.
In H, y being the double of x would be equal to 2/1 again.
And in J, the numbers are also being doubled.
The slope for G would just be 0, which is undefined.
Solve for x: 5 − (x + 5) > −2(x + 4)
x > −8
x −18
x < −18
PLS PLS PLS HURRY I GIVE BRAINLIEST
Answer:
The answer is
[tex] \huge x > - 8[/tex]
Step-by-step explanation:
[tex]5 − (x + 5) > −2(x + 4)[/tex]
First of all expand the terms in the bracket
That's
[tex]5 - x - 5 > - 2x - 8 \\ - x > - 2x - 8[/tex]
Add 2x to both sides
[tex] - x + 2x > 2x - 2x - 8 \\ x > - 8[/tex]
We have the final answer as
[tex]x > - 8 [/tex]
Hope this helps you
Answer:
x > -8
Step-by-step explanation:
5 − (x + 5) > −2(x + 4)
Simplify both sides first:
5 - x - 5 > -2x - 8
-x > -2x -8
Now isolate the variable:
-x > -2x -8
+2x +2x
x > -8

See below.
Step-by-step explanation:
It seems that the question above said that the value of the gift card decreased by $295.
The original amount of the gift card was $400.
$400 - $295 = $105
Once the original amount of the card was decreased by $295, it still has $105 left.
Part 2 of 2
Arleen can buy the wheelbarrow because she has $105 left on the card, and the wheelbarrow costs $100.

im confused someone help
the rectangle had a length that is 6 inches less that twice it's width. If the perimeter is 54, find the dimensions of the rectangle
Answer:
11" x 16"
Step-by-step explanation:
This problem can be solved with an equation
If you translate the first words into an equation, you get:
l = 2w - 6
(where w is width and l is length)
The perimeter (p) of any rectangle is 2l + 2w, so
if p = 54
then 54 = 2l + 2w
Now, you have the following two equations:
l = 2w - 6
2l + 2w = 54
In order to solve this for w, you can replace the l in the equation with (2w - 6) because of the substitution property of equality (if a = b, then a can be replaced with b at any time), so you get:
54 = 2(2w - 6) + 2w
Now, you simplify:
54 = 2(2w - 6) + 2w
= 54 = 4w - 12 + 2w
= 54 = 6w - 12
= 66 = 6w
= w = 11
So the width is 11. In order to find the length you just need to substitute it into the equation for the perimeter:
2l + 2(11) = 54
= 2l + 22 = 54
= 2l = 32
= l = 16
In conclusion, the width is 11 and the length is 16.
