Answer:

37/45 ≈ 0.822

Step-by-step explanation:

The formula for an exponential relation is ...

y = a·b^x

This question is asking for the value of b. It can be found by substituting the given values of x and y, and taking the ratio of the resulting equations.

90 = a·b^15

74 = a·b^16

Dividing the second equation by the first, we have ...

74/90 = (a·b^16)/(a·b^15)

74/90 = b

The decay factor is 74/90 = 37/45 ≈ 0.822

What is <br>y=3x-4and y=x-2

IrinaVladis [17]

Answer:

x= 1

y= -1

Hope this helps!

Step-by-step explanation:

1 Substitute y=3x−4 into y=x-2

3x-4=x-2

2 Solve for x in 3x-4=x-2

x=1

3 Substitute x=1 into y=3x-4

y=-1

4 Therefore,

x=1

y=-1

Please write an equation in slope intercept form that is parallel to the equation

gtnhenbr [62]

Answer:

y=1/4x-1.5

Step-by-step explanation:

So, because the line is parallel, the slope is the same. Then, to get the y-int, you do b=y-mx with the point, so the equation is b=-1-(1/4)(2), then you multiply to get b=-1-(0.5), so your y-int is -1.5.
