A. (-3,1)
B. (-3,4)
C. (1,3)
D. (1,1)
Step-by-step explanation:
Option B is correct.
I'm sure (-3 , 4)
Answer:
x=-3, y=4. (-3, 4). B)
Step-by-step explanation:
7x+2y=-13
-3x-8y=-23
-------------------
4(7x+2y)=4(-13)
-3x-8y=-23
---------------------
28x+8y=-52
-3x-8y=-23
-------------------
25x=-75
x=-75/25
x=-3
7(-3)+2y=-13
-21+2y=-13
2y=-13-(-21)
2y=-13+21
2y=8
y=8/2
y=4

On number line below, length AB =? A16 B45
Answer:29
Step-by-step explanation:
d[AB]=|45-16|=29
A number line is the representation of numbers in real order.
The difference between the consecutive numbers in a number line is always positive.
The length AB is 29.
AB = 29 is our answer.
What is a number line?It is the representation of numbers in real order.
The difference between the consecutive numbers in a number line is always positive.
We have,
A is at point 16.
B is at point 45.
Now,
The distance between A and B.
= B - A
= 45 - 16
= 29
Thus,
The length AB is 29.
AB = 29 is our answer.

Graph a line with a slope of 3/4 that contains the point (2,-3).
Answer:
Start at the y-intercept (0, -4.5) and then use rise over run (Up 3 and right 4)
Step-by-step explanation:
y - y1 = m(x - x1)
y + 3 = 3/4(x - 2)
y + 3 = 3/4x - 3/2
y = 3/4x - 9/2
ILL BRAINLIEST YOU IF YOU GET IT RIGHT
Can you help me match each figure with the appropriate angle pair relationship
Answer:
co interior angle plz take my and
Answer:
1) Alternate exterior
2) alternate interior
3) consecutive interior angles
Alright so here’s a trick
Alternate already means different sides so look for that.
Interior angles are all the angles inside the two parllel lines.
Exterior angles are all angles out side the two parralel lines.
No matter what if its alternative interior or exterior, it should make a perfect
“/“ or back slash.
Consecutive is on the same side.
Corresponing is also on the same side but it has 1 exterior and 1 interior

Slope- intercept equation from a graph
Find the equation of the line
We can find the slope using any two points on the line. Readily identifiable are the points (2, 0) and (0, 3), from which we can find the slope:
[tex]\text{slope} = m=\frac{y_2-y_1}{x_2-x_1} \\ m = \frac{3-0}{0-2} = -\frac{3}{2}.[/tex]
The y-intercept is the y value when x = 0, which we already know is 3. So, the slope-intercept equation of this line is:
[tex]y=-\frac{3}{2}x+3.[/tex]

What is the unit rate for the proportional relationship represented by the equation y=4/5x
Answer choices:
A:4/5
B:-2
C:4
D:5
Answer:
A: 4/5
Step-by-step explanation:
The equation for proportionality is y = kx, where k is the constant of proportionality. That is what you're looking for in this question.
So in y = 4/5x, 4/5 is the constant of proportionality/unit rate for the proportional relationship.
The 4/5 is the constant of proportionality/unit rate for the proportional relationship.
We have given that,
the unit rate for the proportional relationship is represented by the equation y=4/5x.
We have to determine the unit rate
What is the equation of proportionality?The equation for proportionality is y = kx, where k is the constant of proportionality.

Avery deposited 1250 in a new savings account. Which amount is closest to the balance of the account at the end of three years
Answer: $1,467.80
Step-by-step explanation:
The formula for the future value given annual compounding is:
= Amount * ( 1 + rate) ^ number of years
The amount after 3 years at 5.5% is therefore:
= 1,250 * ( 1 + 5.5%)³
= 1,250 * 1.174241375
= $1,467.80
