Answer:

If use a gallon every 30 miles, 30 gallons are good for 900 miles

900÷30=30

If the cost is $1.15 per gallon

$1.15×30=$ 34.50

C. $34.50. A car gets 30 miles per gallon, if the gasoline cost $1.15 per gallon, a 900 miles trip will cost $34.50

This exercise can be solved by simply arithmetic.

Divide the total miles by the miles per gallon:

900/30 = 30

Then, multiply this value by the cost per gallon:

30 x $1.15 = $34.50

Suppose you want to solve the equation 2a + 2b= 2a, where a and b are nonzero real numbers. Describe the solution to this equati

Anna11 [10]

This equation has no solution where 'a' and 'b'
are both non-zero real numbers.

You said 2a + 2b = 2a

Subtract 2a from each side: 2b = 0

'b' must be zero.

And it doesn't matter what the value of 'a' is.
As long as b=0, 'a' can be any number.

What are the characteristics of the function f(x)=2(x-4)^5? Check all that apply

GaryK [48]

Answer:

Option B , C , E are characteristics of the function .

Step-by-step explanation:

Given : function f(x)=2(x-4)^5.

To find : What are the characteristics of the function .

Solution : We have given that f(x)=2 $(x-4)^{5}$ .

By the End Point behavior : if the degree is even and leading coefficient is odd of polynomial of function then left end of graph goes down and right goes up.

Since , Option E is correct.

It has degree 5 therefore, function has 5 zeros and atmost 4 maximua or minimum.

Option C is also correct.

By transformation rule it is vertical stretch and shift to right (B )

Therefore, Option B , C , E are characteristics of the function .

What is the inverse of the function shown?

Umnica [9.8K]

Answer:

The inverse is y = x + 5

Step-by-step explanation:

The general equation of a straight line is;

y = mx + c

In this case , the y-intercept is -5

So the partial equation is;

y = mx - 5

To get m, we use the x-intercept

The x-intercept coordinate is (5,0)

Insert this in the equation , we have;

0 = 5m-5

5m = 5

m = 5/5

m= 1

The equation of the line is thus;

y = x-5

So we want to find the inverse of this;

Replace x with d

y = d-5

Make d the subject of the formula

d = y + 5

replace d with x

x = y + 5

now replace x with y

So we have

y = x + 5
