Answer:
325 miles and 77 dollars
Step-by-step explanation:
First, create equations. Let x equal the miles driven. The first plan expression is 38 + 0.12x and the second plan expression is 51 + 0.08x. Setting these equal and solve for x: 38 + 0.12x = 51 + 0.08x -> 0.04x = 13 -> x = 325 miles.
The cost is found by substituting it into any of the expressions: 51 + 0.08(325) = 77 or 38 + 0.12(325) = 77
Ralphie uses a boat to move merchandise between two shipping ports. The boat can hold no more than 2,016 kilograms of merchandise. Ralphie already has 1,526 kilograms of merchandise loaded onto the boat and wants to load more boxes of merchandise that weigh 67 kilograms each. Which of the following inequalities could be used to solve for x, the number of boxes of merchandise that can still be loaded onto the boat?
A. 67x - 1,526 < 2,016
B.67x < 1,526
C.67x + 1,526 < 2,016
D.67x < 2,016
Answer:
The answer is 67x - 1,526 < 2,016.

Which equation is a linear function? (Look at the photo I attached for the choices) please help me I am confused!
Two linear functions are displayed. Function One is represented by the graph:
The second linear function is y = -4x. Which statement is true about the slope of the two functions?
A) The slope of function one is positive and the slope of function two is negative.
B) Both functions have a negative slope.
C) Both functions have a positive slope.
D) Both functions have the same slope.
Answer:
Option A
Step-by-step explanation:
Function One is represented by the graph. We can see that the slope of the First Function is positive because the formula of slope is
[tex]Slope=\frac{Change\ in\ y}{Change\ in\ x} \\\\[/tex]
And we can see that in the graph the change in y and change in x are both positive as the function is increasing because if we see the graph closely,
When x = 1 the value of y = 2 and when x = 2 the value of y = 4 and when x = 3 the value of y = 6 so the values are increasing of x and of y hence the slope is positive and the value of slope is 2.
Now the Second Function which is y = -4x here the slope is negative because the slope-intercept form of the equation is .
[tex]y=mx+b[/tex]
and the second function is
[tex]y=-4x[/tex]
if we compare both these equations we get the value of m = -4 where m is also called the slope. So the slope of the second function is negative.
So
Option B is incorrect because the slope of the first function is positive
Option C is incorrect because the slope of the second function is negative
Option D is incorrect because the slope of the first function is 2 and the slope of the second function is -4
That leaves us with Option A which is correct, where we can see that the slope of the first function is positive and the slope of the second function is negative
Answer:
A) The slope of function one is positive and the slope of function two is negative.
General Formulas and Concepts:
Algebra I
Slope-Intercept Form: y = mx + b
m - slope b - y-interceptStep-by-step explanation:
We see that the 1st graph has a positive slope; as x increases, the y-value also increases. Therefore, the 1st graph must have a positive slope.
We are given the equation y = -4x as our second line. Using our y = mx + b form, we see that our slope m = -4. Therefore, the 2nd graph has a negative slope.
Our answer choice then would be A, as it is the only one that matches the descriptions.

Tina pet sits to earn extra money. She charges a flat service fee of $20, plus $15 per day. If one of her customers spent less than $110, which of the following inequalities could be used to solve for x, the number of days the customer paid for pet sitting?
A. $15x - $20 < $110
B. $15x < $130
C. $15x < $110
D. $15x + $20 < $110

Greg runs 4 kilometers in 20 minutes. If he keeps running at the same pace, how many kilometers will he run in an hour?
Answer:
12
Step-by-step explanation:
there are 60 minutes in a hour
60/20 is 3
so you muiltply 4 and 3 to get 12
Answer: 12 kilometer
Step-by-step explanation:
If he run 4 kilometer per 20 mins, it will take him one hour to run 12 kilometer.
Original
4 kilometer. X kilometer
——————- = ————————-
20 mins. 60 min
20x3 = 4x3
4x3= 12 kilometer

prove that for any natural value of n the value of the expression (n+2)^2-(n-2)^2 is a multiple of 8.
Answer:
Se below
Step-by-step explanation:
Simplifying, using formula a^2 - b^2 = (a +b)(a - b)
(n + 2)^2 - (n - 2)^2 =(n + 2 + n - 2)(n + 2 - n + 2) =2n(4) =8nAs we see the resulting expression is multiple of 8
Which number line shows 1 to 4 divided into thirds?
Answer:
Line 1.
Step-by-step explanation:
This is because in order for it to be considered thirds, the third has to equal a whole. Line one goes:
1/3 2/3 3/3
This is split into thirds
The required number line that represents the dividend of the three is the fourth line. Option D is correct.
Given that.
To determine the line that has a dividend of 3.
A number line is defined as the number marked on the line calibrated into an equal number of units. For example -1, 0, 1, and so on.
Here,
Line 1 has a dividend of 2,
Line 2 has a dividend of 5
Line 3 has a dividend of 4
Line 4 has a dividend of 3
Thus, the required number line that represents the dividend of the three is the fourth line. Option D is correct.

Ganesh is making a scale model of the Space Needle in Seattle, Washington. The Space Needle is 605 feet tall. If the model is the actual size of the Space Needle, how tall is the model?
Show all your thinking.
Answer:
it says if it was the exact same size thats what i understood so it would be 605ft tall
Step-by-step explanation:
Answer:
The model is 6.05 feet tall.
Step-by-step explanation:
Now to the breakdown.
What does it mean to scale? Scaling is used for representation drawing or model is designed to tell the audience(those interested in the design) the ratio to which the design was done in respect to the actual size.
From the above definition we can scale down or scale up. To scale down is to reduce the dimensions of the actual size in our design (possibly in an effort to conserve available space). To scale up is to enlarge the dimensions of the actual size in our design (possible in an effort to show intricate and tiny parts).
Back to question, The actual size of the space needle is 605 feet to design this using the actual size will require a very large amount of resources. So the scale model is made at a scaled down ratio of 1:100 (in a bid to manage available resources like paper size and others pertaining to the design).
1:100 means that every 1ft in the scale model represents 100ft of the actual model.
So for an Height of 605ft the scale model will have representing height of 605/100 = 6.05ft.
