Answer:
y= -2x - 1
Step-by-step explanation:
that is the answer sorry if wrong
Answer:
(5, -2)
Step-by-step explanation:
Use substitution
Y=5x-27 Put this equation into the place of y in the second one.
2x+3y=4
2x + 3(5x - 27) = 4 then solve for x
2x + 15x - 81 = 4
17x - 81 = 4
17x = 85
x = 5
Then put the value of x back into one of the equations and solve for y
y = 5(5) - 27
y = 25 - 27
y = -2
Answer:
Prat 9)
Part 10)
Part 11)
Part 12)
Step-by-step explanation:
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
SF-----> the scale factor
a----> area of the shaded figure
b----> area of the unshaded figure
Problem 9) we have
substitute in the formula
------> the scale factor
To find the value of x, multiply the length of the unshaded figure by the scale factor
Problem 10) we have
substitute in the formula
------> the scale factor
To find the value of x, multiply the length of the unshaded figure by the scale factor
Problem 11) we have
substitute in the formula
------> the scale factor
To find the value of x, multiply the length of the unshaded figure by the scale factor
Problem 12) we have
substitute in the formula
------> the scale factor
To find the value of x, divide the length of the shaded figure by the scale factor
