I hoped this help and little I didn't understand everything you meant.

The rate to rent a truck for a day is a one-time fee of $35 and $0.20 per mile.

Write an expression to model this situation.
How far could you travel if you drove 40 miles?

Answers

Answer: y= $0.20x + $35 or y= $0.20 * 40 + $35 (Depending on what you mean)

Step-by-step explanation:

The equation for these types of problems is y = mx + b.

M would be $0.20, because that is the value that can repeat, based on x. For example, if this was 2 dollars per mile (m) for 3 miles, (x) than y, the total amount for mx would amount to 6 dollars.

Now, 35$ Is a one time fee (b), so you can add that separately to $0.20x.

If you plug everything in, you would get y= $0.20x + $35.

I am not very sure about what you mean by “ How far you could you travel if you drove 40 miles”, but if you mean how much would you pay to drive 40 miles, I can help there.

Now that we know x would be the amount of miles, we can plug that into the equation.

You would get y= $0.20 * 40 + $35.

Sorry, I’m not that good at explaining, but I hoped this helped!

y= .20x + 35

It would cost $43 to travel 40 miles

Evaluate if x=5 x^2+10

Answers

Answer:

[tex]35[/tex]

Step-by-step explanation:

To evaluate the expression:

[tex]x^2+10[/tex]

First, consider the given information:

[tex]x=5[/tex]

Substitute the given value of [tex]x[/tex] into the expression:

[tex]5^2+10[/tex]

(Note that [tex]5^2[/tex] is the same as [tex]5*5[/tex])

[tex]5*5=25[/tex]

[tex]5^2=25[/tex]

Add:

[tex]25+10=[/tex]

[tex]35[/tex]

We can check our work by setting our solution equal to the initial expression:

[tex]x^2+10=35[/tex]

Substitute [tex]x[/tex] for its given value:

[tex]5^2+10=35[/tex]

Simplify [tex]5^2[/tex]:

[tex]25+10=35[/tex]

Add:

[tex]35=35[/tex]

Since both sides of the equation are equal, our solution is correct!

Answer:

Step-by-step explanation:

Because X=5, the equation is literally just asking 5x5=10. So, following the order of operations, I would do 5x5 first which equals 25 plus 10. Since 25+10=35. The answer is 35. Hope this helps! :p

C:The decimal point should be to the left of the 6.
D:Lucita's estimate is too high.
Thank you to those who end up helping, xx

Answers

Lucita does the division problem. My dad told me you divide the biggest number. (3.302) with the little valued number (1.27) She doesn't understand not because (A) her estimate is too low.

So that leaves A eliminated.

It shouldn't be B because, you have to count the numbers to the left of the decimal.

So that leaves B eliminated.

Let's talk about D, Her estimate is too high. But, take a risk. Either choose C or D. Good luck! I really think this would help thanks to my dad's method.

On the map below, city p and city q are 5.5 centimeters (cm) apart. What is the actual distance between city p and city q? 2cm= 35 miles

Answers

Answer:

96.25

Step-by-step explanation:

5.5/2=2.75

2.75x35=96.25

Ok so 2cm = 35 miles
Meaning ONE centimeter is 35/2, or, 17.5 miles of actual distance
And half, or 0.5 of a centimeter is 17.5/2 or 35/4, which is 8.75 miles
5 centimeters is 2 + 2 + 1 + 0.5
(35 miles) plus (35 miles) plus (17.5 miles) plus (8.75 miles) which would add up to be 96.25 miles

A line passes through the points (1, 4) and (3, –4). Which is the equation of the line?

Answers

y = -4x + 8

First you need to find the slope of the line.

The slope formula is m = y2-y1/x2-x1

If you plugged in the points it would be m = -4-4/3-1

so m = -8/2 = -4

so the slope is -4

now we need to write the equation of the line

for this u use point slope form

the formula for that is y-y2=m(x-x1)

so if you plug it in it would be:

y-(-4)=-4(x-3)

now you solve

y+4=-4x+12

y+4-4= -4x+12-4

y = -4x + 8

and now you have the slope of the line

What is the slope of the line that passes through the points (4, 6)(4,6) and (-16, -18) ? (−16,−18)? Write your answer in the simplest form.

Answers

The slope of the line that passes through the points (4, 6)(4,6) and (-16, -18) is to be considered as the 1.2.

Calculation of the slope of the line:

here we used the following formula

So,

[tex]= y_2-y_1\div x_2-x_1[/tex]

So,

-18-6=-24

And,

-16-4=-20

Now

[tex]= -24\div -20[/tex]

= 1.2

Hence, The slope of the line that passes through the points (4, 6)(4,6) and (-16, -18) is to be considered as the 1.2.

The slope of the line that passes through the points (4, 6) and (-16, -18) is; 6/5.

What is the slope?

The slope is the ratio of the vertical changes to the horizontal changes between two points of the line. Slope of parallel lines are same. Slopes of perpendicular lines are negative reciprocal of each other.

[tex]m = \dfrac{y-q}{x-p}[/tex]

Given that the line that passes through the points (4, 6) and (-16, -18)

WE need to find the slope of the line.

Since, [tex]m = \dfrac{y-q}{x-p}[/tex]

Therefore, m = -18 - 6 / -16 - 4

m = 24 / -20

m = 6/5

Hence, The slope of the line that passes through the points (4, 6) and (-16, -18) is; 6/5.
