y=mx+b
-7=3(2)+b
-7=6+b
-7-6=b
-13=b
put it back into y=mx+b
y=3x-13
Answer:
b=1, Y= -3-1
Step-by-step explanation:
y = -3 + b
-7 = -3(2) + b

find z and x
please help i’ll mark the first one or whoever right brainliest
Answer:
z=97 x=21
Step-by-step explanation:
so straight angles always equal 180°
And assuming that your lines are parallel, the angle under angle z should be 83° just like the angle above angle z
There for to solve for x, first subtract 83 from 180 because that's what that angle is equal to.
Now that you have the equation 4x+13 and you know that it's equal to 97 you can solve it just like a normal inequality.
4x+13=97
4x=84
x=21

What is 50 percent of 62?
0.31
3.1
31
310
Answer:
To get the solution, we are looking for, we need to point out what we know.
1. We assume, that the number 62 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 62 is 100%, so we can write it down as 62=100%.
4. We know, that x is 50% of the output value, so we can write it down as x=50%.
5. Now we have two simple equations:
1) 62=100%
2) x=50%
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
62/x=100%/50%
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.
7. Solution for what is 50% of 62
62/x=100/50
(62/x)*x=(100/50)*x - we multiply both sides of the equation by x
62=2*x - we divide both sides of the equation by (2) to get x
62/2=x
31=x
x=31
now we have:
50% of 62=31
50 percent of 62 is equal to 31. the correct answer is option C) 31.
To convert a number to a percentage, you typically multiply the number by 100 and add the percentage symbol (%).
To find 50 percent of 62, we can calculate it by multiplying 62 by 0.50 (which is equivalent to 50 divided by 100).
62 * 0.50 = 31
Therefore, 50 percent of 62 is equal to 31.
So, the correct answer is option C) 31.
Options A) 0.31, B) 3.1, and D) 310 are not correct as they either incorrectly place the decimal point or exaggerate the value by orders of magnitude. The accurate value is 31.

Answer:
11. A. y = 24x
12. C. c = 0.5p
13. D. p = (1/200)n
14. C. 5 : 8
Step-by-step explanation:
11. y = 24x is correct because you multiply the number of days (x) by 24 to get the number of hours (y)
12. c = 0.5p is correct because there are half as many c as p. so to get c, you multiply p x 1/2.
13. If we substitute in, p is 1/4. 1/200 times n = 0.25 or 1/4. So D. is correct.
14. The ratio of apples to oranges is 15 : 24. We can divide 15 and 24 both by 3 to get 5 : 8.

Start with the top figure. Which transformation was used to create the pattern?
The transformation that was used to create the pattern is rotation. The correct option is A, rotation.
What is the transformation in logic?If two formulae are logically identical, either one may replace the other in any well-formed context without changing anything's truth value or inferential qualities. This is a fundamental property of logic.
The given figure in the top is needed to be transformed such that the pattern given below is produced. Therefore, if we observe the figure at the top and the pattern, then it can be seen that the given figure is rotated by 90° to create the given pattern. The pattern will be formed.
Hence, the transformation that was used to create the pattern is rotation.

Convert the equation from standard form to slope-intercept form.
Answer:
y=x-1
Step-by-step explanation:
The equation is currently in standard form which is a+b=y and slope-intercept is y=mx+b where m is the slope and b is the y-intercept. To change the form we must move the terms around using Properties of Equality.
First, subtract 1 from both sides
x-y-1=1-1
x-y-1=0
Then, add y to both sides
x-y-1+y=0+y
x-1=y
So that is the equation in slope-intercept form with a slope of 1 and a y-intercept of -1.
Answer:
y=x-1
Step-by-step explanation:
It is y=x-1 because first when we do ANYTHING first. We leave the y on the left side of the equation, since the slope y=mx+b has the y always on the left side. So we subtract x from both sides and we get -y=-x+1. We are NOT DONE yet, so after this, we divide both sides by -1. Why? This is because you cannot have a negative y. Dividing both sides by -1 you finally get y=x-1. If this is trouble some to read, I will also put how to solve the problem down below. :)
Let's solve for y.
x−y=1
Step 1: Add -x to both sides.
x−y=1+−x
−x
−y=−x+1
Step 2: Divide both sides by -1.
−y/ −1 = −x+1 /−1
y=x−1
Answer:
y=x−1
