The rate of change is also known as the slope or rise / run.
Slope Formula: (y2 - y1) / (x2 - x1)
First, we'll need two points that are on the line. You can choose any two points you want, as long as they are on the line.
Point 1 = (0, 1)
Point 2 = (-2, -3)
Then, we'll plug the two points into the formula and solve for the slope.
(-3 - 1) / (-2 - 0)
(-4) / (-2)
2
The rate of change of this line is 2.
Hope this helps!! :)
Answer: the rate of change is 2

I have the equation.
16x^0+2x^2*y^-1
How do I solve the equation if x = 2 and y = 4?
Answer:
18
Step-by-step explanation:
[tex] \\ \sf16 {x}^{0} + 2 {x}^{2} \times {y}^{ - 1} [/tex]
Now putting the values of x and y.
[tex] \\ \sf16 \times {2}^{0} + 2 \times {2}^{2} \times {4}^{ - 1} [/tex]
[tex] \\ \sf = 16 \times 1 + 2 \times 4 \times \frac{1}{ {4}}[/tex]
[tex] \\ \sf = 16 + 2[/tex]
[tex] \\ \sf = 18[/tex]
Note:
•If the power of a number is 0 then it's value will be 1.
•If the power of a number is negative then reciprocal the number to make the power positive.
Find the x- and y-intercepts of the graph of — 7x + 8y = 40. State your answers as
whole numbers or as improper fractions in simplest form.
Answer:
x-intercept is (40/7, 0) and y-intercept is (0, 5)
Step-by-step explanation:
x-intercept ==> y-coordinate is 0 ==> y=0
y-intercept ==> x-coordinate is 0 ==> x=0
because the function is 7x + 8y = 40
when y = 0 ==> 7x = 40 ==> x = 40/7
so the x-intercept is (40/7, 0)
when x = 0 ==> 8y = 40 ==> y = 5
so the y-intercept is (0,5)
3b- 4/2 = c , for b
please explain the steps
Answer:
b = c/3 + 2/3
Step-by-step explanation:
3b - 4/2 = c
the goal is to have b all by itself on one side of the equals sign.
start by moving the fraction over to where c is by adding.
3b = c + 4/2
adding -4/2 and +4/2 together makes it a 0 on the b side so there's no need to write anything in that space anymore.
Now 3b are next to each other which means they are multiplying. To move 3 we need to do the opposite (divide by 3 on both sides of the equal sign)
b = c/3 + 2/3
notice I divided both c and 4/2 by 3. 4/2 = 2 so I changed it to 2, then divided by 3
Find the missing side of each triangle.
A) 10 cm
C) 17.1 cm
E) 5.8 cm
B) 11.4 cm
D) 13.8 cm
Answer:
The choice B) 11.4
Step-by-step explanation:
[tex] {x}^{2} + {(5.5)}^{2} = {(12.7)}^{2} \\ {x}^{2} + 30.25 = 161.29 \\ {x}^{2} = 13104 \\ x = 11.4[/tex]
By using Pythagoras theorem :
[tex] {x}^{2} = (12.7) {}^{2} - (5.5)x {}^{2} [/tex][tex] {x}^{2} = 161.29 - 30.25[/tex][tex] {x}^{2} =131.04[/tex][tex]x = \sqrt{131.04} [/tex][tex]x = 11.4[/tex]Correct choice is B

Carmen wants to buy a pair of shoes that regularly costs $78. Today, the shoes are on sale for 60% of the original price. How much will Carmen have to pay for the shoes?
Answer:
31.2
Step-by-step explanation:
Change 60% into 0.6 by moving the decimal 2 points to the left
Multiply 0.6 by 78 to get 46.8
Subtract 78 and 46.8 to get 31.2 which is your answer
This is so hard and I don’t know why
Answer:
Hey girl! I got you.
Step-by-step explanation:
So! The angle x and z are congruent, meaning that they are equal, so you got that part correct. They are indeed 103. Next you need to find y, and in this case you need to do 180 - 103 because the line that holds both angle z and angle y is equal to 180.
180 - 103 = 77, you got that correct also!
You're on the right track, just explain in words how you know what each angle is equal to! Good luck! :)

A waiter earns $6 per hour plus tips of 15% of the restaurant tab from each table served . What total amount of restaurant tabs assures the waiter of making at least $350 in a 5 hour shift ?
Answer:
$2133.33Step-by-step explanation:
Given:
Rate per hour = $6Number of hours = 5Tips = 15%Lets the total amount of tabs = t
We have inequality:
6*5 + 0.15t ≥ 35030 + 0.15t ≥ 3500.15t ≥ 320t ≥ 320/0.15t ≥ 2133.33Greg drives at 50 mph for 2 hours.

Answer: 3.5 years
Step-by-step explanation: Let A be the salaries earned from company A for x years and B for company B for the same years.
A = 31000 + n*3000
B = 38000 + n*1000
To find the case where A = b, set them to each other and solve for n, the number of years.
31000 + n*3000 = 38000 + n*1000
2000n = 7000
n = (7000/2000) = 3.5 years.

Question 7 = 2 Points
Oct 06, 8:37:22 PM
Samantha has $600 to spend at a bicycle store for some new gear and biking outfits.
Assume all prices listed include tax,
• She buys a new bicycle for $399,95
• She buys 3 bicycle reflectors for $7.01 each and a pair of bike gloves for $34.06.
• She plans to spend some or all of the money she has left to buy new bilding outfits
for $75,88 each
Write and solve an inequality which can be used to determine w, the number of
outfits Samantha can purchase while staying within her budget
Answer:
See belowStep-by-step explanation:
The budget is $600.
Samantha spends the following amount:
399.95 + 3*7.01 + 34.06 = 455.04Now, she plans to buy w outfits which cost $75.88 each.
The inequality for this is:
455.04 + 75.88w ≤ 600Solving this we get:
75.88w ≤ 600 - 455.0475.88w ≤ 144.96w ≤ 144.96 / 75.88w ≤ 1.91w = 1 is the only integer solution greater than zero
