Answer:
x=1
y=-4
Step-by-step explanation:
4x+y=0 -> y= -4x
2(-4x)+x=-7
-8x+ x=-7
-7x=-7
x=-7/-7=1
y=-4 . 1 = -4
Answer:
1.) $1.07

Answer:
3/2 * square root of 2
This is the correct answer
Step-by-step explanation:
3/14 * square root 98 =
= square root of 98 * 3/14^2 =
= square root of 98 * 9/196 =
= square root of 9/2
3/2 * square root of 2 =
= square root of 2 * 9/4 =
= square root of 9/2
square root of 9/2 = square root of 9/2
The formula for area of a triangle is: 1/2 x base x height.
You are given the height of 4 and the area of 4.
Replace those in the formula and solve for x ( base)
4 = 1/2 x base x 4
Divide both sides by 4:
1 = 1/2 x base
Multiply both sides by 2:
2 = base
x = 2
59 because if you do 3x8 that equals 24 and then you do 35+24 that equals 59
