Answer:
12b+6e+9
Step-by-step explanation:
You multiply 3 with every number inside the parentheses.
(3x4b)=12b
(3x2e)=6e
(3x3)=9
3x - 3y = 33
6x - 3y = 57

write in slope form 2y = 24
Answer:
y = 12
Step-by-step explanation:
The equation of the expression is given as;
2y = 24
We are to write in slope form';
In slope form, an equation is expressed as;
y = mx + c
where y and x are the intercept
m is the slope
c is the intercept
Now to write 2y = 24 in intercept form, we have;
2y = 24
divide both sides by 2;
y = 12
What are the coordinates of the midpoint of AB IF A (6,4) and B (-8,8)
Answer:
-I haven't done this, but I have copied and pasted from another question and answer from the user syed514:
Graphing is one way to do the problem.But sometimes, graphing it is hard to do.So here’s an algebraic method.
If M(m1, m2) is the midpoint of two points A(x1, y1) and B(x2, y2),then m1 = (x1 + x2)/2 and m2 = (y1 + y2)/2.In other words, the x-coordinate of the midpointis the average of the x-coordinates of the two points,and the y-coordinate of the midpointis the average of the y-coordinates of the two points.
Let B have coordinates (x2, y2) in our problem.Then we have that 6 = (2 + x2)/2 and 8 = (3 + y2)/2.
Solving for the coordinates gives x2 = 10, y2 = 13

Sam takes out a $167,000 mortgage for 20 years. He makes monthly payments and at the end calculates that he has paid $240,141 towards the mortgage. What is the approximate APR?
3%
4%
6%
7%
Answer:
About 3%
Step-by-step explanation:
3% of $167,000 is $5,010
5010 times the 20 years is 100200 add that to the 167000 and you get $267,200
The actual answer is about 2.4% but 3% is the closest.

boris's super metal detector not only helped him win the science fair but also helped him find $6.20 in nickels and dimes yesterday morning. If boris found 14 more dimes than nickels, how many nickels did he find
Answer:
32 Nickels
Step-by-step explanation:
Given
Coins: Nickels (N) and Dimes (D)
$0.05 = 1 nickel and $0.10 = 1 dime
So, the amount implies:
[tex]0.05N + 0.10D = 6.20[/tex]
The number of coin implies:
[tex]D = 14 + N[/tex]
Required
Determine the number of nickels found
Substitute 14 + N for D in [tex]0.05N + 0.10D = 6.20[/tex]
[tex]0.05N + 0.10(14 + N) = 6.20[/tex]
[tex]0.05N + 1.4 + 0.10N = 6.20[/tex]
Collect Like Terms
[tex]0.05N + 0.10N = 6.20 - 1.4[/tex]
[tex]0.15N = 4.8[/tex]
Solve for N
[tex]N = 4.8/0.15[/tex]
[tex]N = 32[/tex]
Hence, he found 32 nickels
SOLVE: 1/4 (20-4a)=6-a (show work please)
Answer:

Answer:
[tex]y=-4x^{2} +7x+6\\[/tex]
Step-by-step explanation:
[tex]y=ax^{2} +bx+c\\[/tex]
Points are (1,9), (2,4), and (4,-30).
[tex]\\9=a+b+c\\4=4a+2b+c\\-30=16a+4b+c\\[/tex]
Subtract the first from the second.
-5 = 3a+b
Subtract 4 times the second from the third.
-34=12a+2b
-14=-2b
b=7
a=-4
c=6
Which equation represents a proportional relationship?
A. y = x + 1
B. y = 3x + 3
C. y = 4x
D. y = 8 + x
Answer: C. y=4x
Step-by-step explanation:
Proportional relationship means that the line will be going through the origin, meaning that if the x coordinate is 0, then y has to also equal to 0. Also another way to determine a proportional relationship is by identifying the slope and y intercept. If the line has a y-intercept then it is not proportional because it will not be going through the origin.
y = 4x Input 0 for x and y.
0 = 4(0)
0 = 0
This makes the statement true because if x is 0 then y is also 0.

Step 1: Identify
The drawing states that we are looking for the height of the tree.
h = unknown
horizontal length = 26
∅ = 24°
We will have to use tangent to solve for the missing length
Step 2: Solve for h
Substitute: tan24° = h/26Multiply both sides by 26: 26tan24° = hRewrite: h = 26tan24°Evaluate: h = 11.5759Answer:
