Answer:
Let's solve for x.
4x+2y=5
Step 1: Add -2y to both sides.
4x+2y+−2y=5+−2y
4x=−2y+5
Step 2: Divide both sides by 4.

Let's solve for x.
−4x−5y=7
Step 1: Add 5y to both sides.
−4x−5y+5y=7+5y
−4x=5y+7
Step 2: Divide both sides by -4.

Answer:
Area= 70x^3y^2
Perimeter = 20x^2 + 14 xy^2
Step-by-step explanation:
Area is just multiplying the length and width, I multiplied the constants first which gets us 70 then multiplied the variables, they combine however only the x's can be multiplied to each other which results in 70x^3y^2 . The perimeter you just multiply the length by two and the width by two, they are separate because the variables when added to each other do not combine.
Answer:
B
Step-by-step explanation:
Since ∠ E = ∠ F then the triangle is isosceles and DF = DE, that is
6x = x + 2y ( subtract x from both sides )
5x = 2y ( subtract 2y from both sides )
5x - 2y = 0 → (1)
and perimeter = 29, that is
6x x + 2y + 5x - y = 29 , simplifying
12x + y = 29 → (2)
Multiply (2) by 2
24x + 2y = 58 → (3)
Add (1) and (3) term by term to eliminate y, that is
29x = 58 ( divide both sides by 29 )
x = 2
Substitute x = 2 into (2) and evaluate for y
12(2) + y = 29
24 + y = 29 ( subtract 24 from both sides )
y = 5
Thus
FE = 5x - y = 5(2) - 5 = 10 - 5 = 5 → B
Answer:
D)
Step-by-step explanation:
Coefficient of x is -3/2 and so multiply the whole equation by 2
3x + 2y = -8
