Question

y= 3x +5
when x= 10 what is the value of y
when x= -10 what is the value of y
which equation below gives the same value if y fit both x= 10 and x=-10?
a. y= 10x b. y=2x c. y=x+10 d. y=x2

Answer 1

Answer:

a) y = 35

b) y = -25

c) Option D

Answer 2

Answer:

y = 35

y = -25

y = x^2

Step-by-step explanation:

y = 3x + 5

a) when x = 10, what is the value of y?

y = 3x +5

y = 3(10) + 5

y = 30 + 5

y = 35

b) when x= -10 what is the value of y?

y = 3x + 5

y = 3 (-10) + 5

y = -30 + 5

y = -25

c) y = x^2

because 10^2 = 100 and -10^2 = 100

Hope this helps!
