Answer: $7.6502

Step-by-step explanation:

Grape cost $1.19 per pound. 3.16 pounds are bought. The total amount paid for grape will be:

= $1.19 × 3.16

= $3.7604

Peaches cost $1.29 per pound. 1.35 pounds are bought. The total amount paid for peaches will be:

= $1.29 × 1.35

= $1.7415

Peers cost $0.99 per pound. 2.17 pounds are bought. The total amount paid for pears will be:

= $0.99 × 2.17

= $2.1483

Total bill paid will be:

= $3.7604 + $1.7415 + $2.1483

= $7.6502

Which two functions are inverses of each other?
guapka [62]

Answer:

The choices were typed wrong, but we can find the inverse of each option.

For function f(x)=x the inverse is the same function g(x)=x, because an inverse of a function is where their composition gives the independent variable as unique result.

If we do that with each function, we have:

f((g(x))=x; where f(x)=x and g(x)=x, we have

f((g(x))=x\\x=x

So they are inverse.

For f(x)=2x its inverse would be g(x)=\frac{1}{2}x, because

f(g(x))=2(\frac{1}{2}x)=x

For f(x)=4x, its inverse is g(x)=\frac{1}{4}x, because

f(g(x))=4(\frac{1}{4}x)=x

For f(x)=-8x, its inverse is g(x)=-\frac{1}{8}x, because

f(g(x))=-8(-\frac{1}{8}x)=x

There you have all inverses. Basically, if their composition results in x, that means they are inverse.

HELP PLEASE!
Novosadov [1.4K]

Answer:

x = 25

Step-by-step explanation:

This is an equilateral triangle as all 3 angles are marked as equal.

Hence the 3 sides are equal

Equate any 2 and solve for x

4x - 30 = 3x - 5 ( subtract 3x from both sides )

x - 30 = - 5 ( add 30 to both sides )

x = 25

As a check on the sides

4x - 30 = (4 × 25) - 30 = 100 - 30 = 70

3x - 5 = (3 × 25 ) - 5 = 75 - 5 = 70

2x + 20 = (2 × 25 ) + 20 = 50 + 20 = 70

confirming that x = 25

You know the slope of a line and a point on the line that is not the y-intercept. Can you use a graph to write the equation of t
Gnoma [55]
Sure you could as long as you have the point.

for example let's say the slope is 2 and the point we are given is (4,4)

we know that:
y = mx + b
plug in the values given
x=4
y=4
m=2

4 = 2(4) + b
b, the y intercept equals -4.

so:

y = 2x - 4
in this case
