Answer: y=3x+1
Step-by-step explanation:
First find slope using formula
m= y2–y1/x2–x1
m= 4– (—2)/ 1— (—1)
m= 3
So,
y= mx+b
y=3x+b. Using (1,4) plug into equation of a line
4= 3(1)+b
4 – 3= b
1= b. So,
y=3x+1
Answer:
y= 3x+1.
Step-by-step explanation:
(-1,-2) and (1,4)
x1 = -1
x2= 1
y1= -2
y2=4
y - y1= (y2 - y1)
______ ( x - x1)
(x2 - x1)
y- (-2)=(4-(-2))
_____ (x- (-1))
(1-(-1))
y+2= 4+2
___ (x+1)
1+1
y+2= 6
_ (x + 1)
2
y+2=3(x+1)
y+2=3x+3
y=3x+1.
What is the surface area of the square pyramid? 3 m 2 m 2 m
Answer: I believe it is 16
Step-by-step explanation:
because each triangle is the same so all of them have the same outcome so we do 3 x 4 which is 12 and then we do the square 2 x 2 which is 4 so 12 + 4 which is 16
h(x) = x^2+ 2x- 6
what’s the answer
It equals this graph expression. it's a little cropped, but I'm Sure you know about the y & x axis.

The sides of a square are all increased by 2 inches. The area of the NEW square is 49
inches squared. What is the length of a side of the original square?
A: 4.5 inches
B: 9 inches
C: 5 inches
D: 2 inches
9514 1404 393
Answer:
C: 5 inches
Step-by-step explanation:
The length of the sides of the new square is the square root of the area:
s = √A = √49 = 7
The original square had sides 2 inches shorter, so they were ...
7 in -2 in = 5 in . . . . side length of original square

1. Which of the following statements best represents the graph?
A. After one month of service, the cost of internet is $45.
B. After 60 months of service, the cost of internet is $1.
C. After one months of service, the cost of internet is $60.
D. After 5 months of service, the cost of internet is $210.
PLEASE ALSO ANSWER THE QUESTION BELOW.
2. Which is the correct equation best reflects to the graph above on question 1?
A. Y = 90x
B. Y = 180x
C. Y = 45x
D. Both B and C

Answer:
A. After one month of service, the cost of internet is $45.
Step-by-step explanation:
If you count on the graph, it goes up 1.5 and over (right) 2. This means to get from 2 months to 1 month, you would go DOWN 1.5 and LEFT 2, which gets you at $45 dollars for the first month.
Calculate (0.25) x (0.44). Show your work.
Answer:
0.11
Step-by-step explanation:
0.44/x=100/25
(0.44/x)*x=(100/25)*x
0.44=4*x
0.44/4=x
0.11=x
What is the magnitude of -3+ 4i?
Answer:
5
Step-by-step explanation:
d² = (-3)² + 4²
d² = 9 + 16
d² = 25
d = 5
Answer:
The magnitude is 5.
Step-by-step explanation:
(I’m going to be using r to represent the magnitude)
r^2= (-3)^2+4^2
r^2= 9+16
r^2= 25
r = 5

The measure of the minor arc in the circle shown below is
degrees.
210°
Part B
If the radius of the circle is 12 inches, the area of the sector contained by the minor arc and two radii is:
(b)
357 in.
B 557 in.
2
607 in.2
D757 in.
Answer:
[tex]A=60\pi\ in^2[/tex]
Step-by-step explanation:
The angle made by the major arc = 210°
The sum of the measure of major arc and the minor arc is equal to 360°.
Minor arc = 360° - 210° = 150°
The radius of the circle, r = 12 inches
The area of the sector is given by :
[tex]A=\dfrac{\theta}{360}\times \pi r^2\\\\=\dfrac{150}{360}\times \pi (12)^2\\\\=60\pi\ in^2[/tex]
So, the correct option is (c) i.e. [tex]60\pi\ in^2[/tex].
Function Composition:
Let the function [tex]f(x)= 3x + 2[/tex] and [tex]g(x) = \frac{x+3}{2x-10}[/tex] , determine:
Answer:
Given
f(x) = 3x + 2g(x) = (x + 3) / (2x - 10)#1
g · f(x) = g(f(x)) = (3x + 2 + 3)/ (2(3x + 2) - 10) = (3x + 5) / (6x - 6)#2
f · g(x) = f(g(x)) = 3[(3x + 2) / (2x - 10)] + 2 = (9x + 6) / (2x - 10) + 2 = (9x + 6 + 4x - 20)/ (2x - 10) = (13x - 14) / (2x - 10)What is the volume of the prism shown below?

How much larger is the volume of a triangular prism when you double the height of the prism?
9514 1404 393
Answer:
2 times
Step-by-step explanation:
Other things remaining the same, the volume of any prism is proportional to its height. If you double the height, it is like having two prisms of the same size. The volume doubles. The new volume is 2 times the original volume.
