Answer:

x = - 3h

Step-by-step explanation:

Given

$\frac{x}{h}$ + 1 = - 2 ( subtract 1 from both sides )

$\frac{x}{h}$ = - 3 ( multiply both sides by h )

x = - 3h

Step-by-step explanation:

$\frac{x}{h + 1} = - 2$

Cross multiply

We have

-2(h + 1) = x

Expand the terms in the bracket

We have the final answer as

x = -2h - 2

Hope this helps you

Point A is at (3, 2.5) and point B is at (3, 1.4) on a coordinate grid. The distance between the two points is ____. Input numbe

andriy [413]

The points have the same x-coordinate, so they lie on a horizontal line. The distance between them is the difference between their y-coordinates.

2.5 - 1.4 = 1.1

The distance between the two points is 1.1

Graham paid $87.45 for a pair of jeans. This amount included a tax of 40%. What was the cost of the jeans before tax?

kiruha [24]

The final price is the cost plus the tax.

Since we know the tax and a percent, we can write this as

T = C(1+r)

T = what Graham paid = $87.45

C = cost before tax

r = tax rate expressed as a decimal = .40

Plugging in what we know

87.45 = C (1+.4)

87.45 = C(1.4)

Divide both sides by 1.4

C = $62.46

F(x)=2x^3+2x-3 g(x)=-.5[x-4] what is the y value when f(x) = g(x)?

Charra [1.4K]

Answer:

D. x = 0.5

Step-by-step explanation:

A graphing calculator is the quickest way to get to an answer here.

f(x) = g(x) for x = 0.5

We can find the y-intercepts of the two functions to be ...

f(0) = -3

g(0) = -2

We know the x-intercept of g(x) is x=4. The x-intercept of f(x) will be a value less than 1, because f(1) = 1. (The function crosses the x-axis between x=0 where f(x) < 0 and x=1, where f(x) > 0.)

Considering these intercept points, we know the value of x for f(x)=g(x) will be between x=0 and x=1. There is only one answer choice in that interval:

x = 0.5
