y :
x +
Answer:
[tex]y=-\frac{1}{2} x+1[/tex]
Step-by-step explanation:
→ Pick 2 coordinates
( 0 , 1 ) and ( 2 , 2 )
→ Find the gradient
[tex]\frac{2-1}{0-2}= -\frac{1}{2}[/tex]
→ Write into y = mx + c
y = -0.5x + c
→ Substitute in ( 0 , 1 )
1 = 0 + c
→ Find c
c = 1
→ Rewrite everything into y = mx + c

please show work 7r + 21 = 49r
Answer:
1/2 = r
Step-by-step explanation:
7r + 21 = 49r
Subtract 7r from each side
7r-7r + 21 = 49r-7r
21 = 42r
Divide each side by 2
21/42 = 42r/42
1/2 = r
Answer:
r = 0.5
Step-by-step explanation:
First you need to isolate the r variable.
7r + 21 = 49r
-7r -7r
21 = 42r
Then Divide both sides by 42
0.5 = r
Now check your answer by inserting it back into the original equation.
7(0.5) + 21 = 49(0.5)
3.5 + 21 = 24.5
24.5 = 24.5
The equation is true so r = 0.5

There are 2 numbers that add up to 32. If one number is eight more than three times the other, find the two numbers.
Answer:
8 and 24
Step-by-step explanation:
let one no. be x
and another be 3x
Their sum = 32
Now,
x + 3x=32
4x=32
x=32/4
x=8
Hence, one number is x =8 and another is 3x = 3*8=24
Hope it helps you a lot..️
The two numbers are 6 and 26
From the given statement, we can form the following equations;
Let the first number = x
let the second number = y
The 2 numbers that add up to 32:
x + y = 32 ---------- (1)
If one number is eight more than three times the other:
x = 3y + 8 -------(2)
Substitute the value of x into equation (1) and solve for the second number
3y + 8 + y = 32
4y = 32 - 8
4y = 24
[tex]y = \frac{24}{4} = 6[/tex]
The value of the first number, x, is calculated as;
x = 3(6) + 8
x = 18 + 8
x = 26
Thus, the two numbers are 6 and 26

2. corresponding points on similar figures are on the same line through the center of dilation
3. corresponding angles in similar figures are congruent
Step-by-step explanation:
1. Your image is distorted, so it is not easy to draw a "straight" line on the provided graphs.
In problem (a), the top corner of figure B at lower right does not line up with the corresponding corners of figures A and C. Figure B is not similar to the other two.
In problem (b), the corners of figure C do not line up with the corners of figures A and B. Figure C is not similar to the other two.
__
2. Corresponding corners of similar figures will be on the same line through the center of dilation. If a "corresponding" point is not on the line, then the figure is not similar.
We examined lines through corresponding points to see if they went through the center of dilation. If a line does not do that, then the figures are not similar. By looking at (two) pairs of figures we can determine which is not similar to the others.
__
3. The usual properties of interest for similar figures are ...
corresponding sides are proportionalcorresponding angles are congruentFor dilated figures, the sides will be proportional if corresponding end points are on the same line through the center of dilation and the corresponding sides are parallel.

complementary angles with measures 2x - 2 and 5x – 13
Answer:
1st angle is 28° and the 2nd angle is 62°
Step-by-step explanation:
Complementary angles mean that the angles add up to 90 so:

Step-by-step explanation:
Drawing graphs will help you understand better
S1
y = 25x + 100
S2
y = 30x + 50
Where y is the total cost that needs to be paid
And x is the number of packages

y = 25(5) + 100
y = 125 + 100
y = 225
Store 2
y = 30(5) + 50

A washer and dryer cost $803 combind the washer costs $47 less then the dryer whats is the cost of the dryer
Answer:
the dryer costs $425
Step-by-step explanation:
x = washer
y = dryer
x + y = 803
x = y - 47
using the second equation a substitute in the first equation we get
y - 47 + y = 803
2y = 850
y = $425
FYI
x = y - 47 = 425 - 47 = $378
Answer:
The dryer costs $425
Step-by-step explanation:
803 - 47 = 756
756 / 2 = 378 (price of the washer)
378 + 47 = 425 (price of the dryer)

Answer:
y = 50
x = 80
Step-by-step explanation:
An isosceles triangle therefore has both two equal sides and two equal angles.
the 2 equal angles are y and and the one next to the 130 degree
so 180- 130 = 50
y = 50
x = 180 - 50 -50 = 80 degree
Step-by-step explanation:
let, the reaming angle be z
z+130°=180°{being straight angle}z=180-130z=50°again,
z=y { base angle of isosceles triangle are equal}also,
