I'm going to use B as my example to explain: B (-3,4)
You are going to need to draw a coordinate plane. When drawing the X axis, you want the highest X point to be 6 due to the fact that that is your highest x value. Then you want the lowest X point to be -6. Same will apply with the Y axis.
Next you are going to put a point in the middle of the plane which is called the origin (0,0).
Going from the origin, you want to follow the x axis the get to -3 which will be going left since its negative. Then since the Y axis is vertical, you are going to go up 4 times since the 4 is positive.
Then start from the origin for the next point being C (-5,4), Remember to always start from the origin.

The ratio of quarters to dimes in a money bag is 21:18. If the total number of coins is 147,how many dimes are there?
21 + 18 = 39
147/39 = 3.7692307692307
3.7692307692307 x 18 = 67.846153846152, round to 67.80 and that's your answer

HELPPPPPP. If the slope of a line through the points (-2,5) and (3, b) is -1, what is the value of b?
Answer:
(C) b = 0.
Step-by-step explanation:
Slope = (b - 5) / (3 - (-2)) = -1
(b - 5)/ 5 = -1
b - 5 = -5
b = -5 + 5 = 0.
6. What is an equation in slope-intercept form for the line that passes through the points and (3, 1)? y= 3x + 1 y=x-3 y=2x + 5 y= 2x - 5
Answer:
The correct answer is D) y = 2x - 5
To find the equation of the line, start by finding the slope. You can do this by using the slope formula below.
m(slope) = (y2 - y1)/(x2 - x1)
m = (1 - -3)/(3 - 1)
m = 4/2
m = 2
Now that we have the slope, we can use it along with either point in point-slope form to get the equation.
y - y1 = m(x - x1)
y - 1 = 2(x - 3)
y - 1 = 2x - 6
y = 2x - 5
Answer: y=2x-5
the points are 4 points away from each other vertically, and 2 away horizontally. This makes the slope 4/2 or just 2.
take the slope and go backwards until you hit the y axis and the y-intercept is -5
this means the equation is y=2x-5

The cost of laying wood floors consists of a base price of $250, plus $3.50 for each square foot installed. Write a function that represents the total cost of installing wood floors.
Answer:
Let s = each square foot of wood installed
Step-by-step explanation:
Total cost of laying wood = base price + price for each square foot installed
Base price = $250
Price for each square foot installed = $3.50
Let
s = number of each square foot installed
Total cost of laying wood = $250 + $3.50s
The correct answer is
Let s = each square foot of wood installed

Explain step by step of how you would find the scale factor for the following problem.
Answer:
Scale factor = 2.5.
Step-by-step explanation:
Work out the lengths of the corresponding sides.
The scale factor is the ratio of one side to the other.
Take the smallest length in both triangles.
Blue triangle:
length = √((7.5-2.5)^2 + (12.5-5)^2) = 9.0139 units.
Red triangle:
length = √((3-1)^2 + (5-2)^2) =3.6056
So the scale factor
= 9.0139/ 3.6056
= 2.5.
if ab=12 and a^2+b^2=25 ,then what is (a+b)^2=
Answer:
49
Step-by-step explanation:
Multiply out (a+b)^2
(a+b)^2 = (a+b)(a+b) = a^2 + ab + ba + b^2 ; not ab = ba so,
= a^2 + 2ab + b^2 = a^2 + b^2 + 2ab ; now subtitue in given values
=25 + 2(12) = 25 + 24 = 49
So (a+b)^2 = 49

Step-by-step explanation:
Triangle P is mapped onto Q so P is the initial triangle that will transformed.
We can rotate counterclockwise 90° but we cannot do it about the origin (0,0) because the red point (5, 1) will end up at ( -1, 5) .
We see that the point (5, 1) ends up at ( -2, 4) so the center of rotation is lower than the origin.
The transformation is rotation of 90° about the point (0,-1)
Which of these functions is a transformation of the function f(x) = 3^x where the function is translated 2 units to the right and horizontally stretched by a factor of 4?
A: g(x)= 3^(1/4x - 1/2)
B: g(x)= 3^(1/4x + 1/2)
C: g(x)= 3^4x - 8
D: g(x)= 3^4x +8
Answer:
A: g(x)= 3^(1/4x - 1/2)
Step-by-step explanation:
A. translated 1/2 units to the right and horizontally stretched by a factor of 4
(If question is translated 2 units to the right, there is no solution in all 4 options)
Make x the subject of the formula
y = (ax)2
Answer:
y = (ax)2
y = 2ax
divide both sides by 2a to make x the subject of the formula.
y/2a = 2ax/2a
x = y/ 2a

A puppy named Taffy started out at 5 pounds and gained 2 pounds every month.what is the slope????
Answer:
y=2x+5 slope: 2
Step-by-step explanation:
Ok so basically we know that Taffy started out with 5 pounds. And then as every month progressed she got 2 more. Meaning you are adding to the 5 pounds she started out with. Slope is a rate and in this case it's per month she gets 2 more! Hope that makes sense

Evaluate: [(1/2)^2-(1/4)^3]
Answer:
15/64
Step-by-step explanation:
Evaluate:
[(1/2)²-(1/4)³]
We have to find the value of expression ?
Explanation:-
Given that
[(1/2)²-(1/4)³]
⇛ [{(1/2)×(1/2)}-{(1/4)×(1/4)×(1/4)}]
⇛ [{(1×1)/(2×2)}-{(1×1×1)/(4×4×4)}]
⇛ [(1/4)-(1/64)]
LCM of 4 and 64 = 64
⇛ [(1×16)-(1×1)]/64
⇛ (16-1)/64
⇛ 15/64
The value of the given expression is 15/64.

Find the area of ABCD. Explain or show reasoning.
Answer:
16, Each side of the sqaure is 4 sq. units. 4+4+4+4=16 The area is also 16. 4x4=16
Step-by-step explanation:
The proof that shows that the quadrilateral is a square is from that fact that all of the sides have the same length.
The perimeter of the quadrilateral is given as
4+4+4+4 = 16
The area of the quadrilateral4L = 4X4 = 16
Hence it has being proven that the area and the perimeter of the shape is 16 hence this shape can be said to be a square.
