How many solutions does y=-7x+8 y=-7x-8 have?
OLga [1]

Answer:

no solutions

Step-by-step explanation:

Given the 2 equations

y = - 7x + 8 → (1)

y = - 7x - 8 → (2)

Substitute y = - 7x - 8 into (1)

- 7x - 8 = - 7x + 8 ( add 8 to both sides )

- 7x = - 7x + 16 (add 7x to both sides )

0 = 16 ← not possible

This indicates the system has no solutions

Answer:

x=55

a=11.47

Step-by-step explanation:

To find x we add all the angles in the triangle.  The three angles in a triangle add to 180 degrees

35+x+90 = 180

Combine like terms

125+x=180

Subtract 125 from each side

125-125+x=180-125

x= 55

To find a

sin 35 = opposite side/ hypotenuse

sin 35 =a/20

Multiply each side by 20

20sin35 =a

11.47152873 =a
