3 0

Answer:

y= 5x......eqn(1)

-2x+2y= 12......eqn(2)

now

substituting value of eeqn(1) in eqn(2) ,

-2x+2(5x) =12

-2x + 10x = 12

8x = 12

X = 12 ÷ 8

X= 3/2

now put value of X in eqn (1)

y= 5x

y = 5 × 3/2

y = 15/2

Step-by-step explanation:

not sure any ans but I tried my best : )

Answer:

Im taking this right now so Im not 100% sure

Step-by-step explanation:

y-intercept: 2 because the slope is passing through 2.

slope: take points (-1,2) and (-1,3)

m=Y2-Y1/X2-X1

m=3-2/-1-1

m=-1/2 or 1/-2(there is no difference)

so the slope is -1/2

b=2

in slope intercept, its going to be:y=-1/2x+2

btw, i noticed that the point isn't -1 it's 0.75 i think. Substitute the -1 for -0.75(-3/4) and finish the math. Sorry.

Determine the period of the following trigonometric function.<br> y=4cos(8πx)
Diano4ka-milaya [45]

The period of y = 4 cos(8πx) is 2π/(8π) = 1/4, since

cos(x - 2π) = cos(x)

and if we replace x with 8πx, we get

cos(8πx - 2π) = cos(8πx)

and

8πx - 2π = 8π (x - 1/4)
