Answer:
x = 7
Step-by-step explanation:
The sum of the interior angles is 90°, so you have ...
(7x +8) +(5x -2) = 90
12x = 84 . . . . subtract 6; next, divide by 12
x = 7
Write the equation of the line that passes through the points (1,4) and (-7,1). Put
your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
There are two possible answers
y - 4 = (3/8)(x - 1)y - 1 = (3/8)(x + 7)There are two answers because there are 2 points given. Both equations convert to the slope intercept form equation y = (3/8)x + 29/8
=================================================
Work Shown:
First we need the slope
m = (y2 - y1)/(x2 - x1)
m = (1-4)/(-7-1)
m = -3/(-8)
m = 3/8
-------------------
Using this slope along with the point (x1,y1) = (1,4) gets us the following equation
y - y1 = m(x - x1)
y - 4 = (3/8)(x - 1)
which is one way to express the equation in point-slope form
-------------------
Or we could easily use the other point as (x1,y1). The order of the points does not matter.
y - y1 = m(x - x1)
y - 1 = (3/8)(x - (-7))
y - 1 = (3/8)(x + 7)
is another valid answer.

What would be the steps you would
take to solve the following problem?
5-2x=13
Answer:
-4
Step-by-step explanation:
1. Subtract the 5 from both sides
2. Now you have -2x=8. From here you are going to divide -2 from both sides to isolate the x value
3. Once you've done that you will have x=-4
The weight of meteorite A is 2 times the weight of meteorite B. If the sum of their weights is 69 tons, find the weight of each.
Answer:
Meteorite A= 46 Meteorite B = 23
Step-by-step explanation:
We can solve this problem by making an equation in which we add the weights, A + B = 69
We are told that A is equal to 2 times the weight of meteorite B, in other words, A is equal to 2B
We can make this into an equation and solve for B'
A + B = 692B + B = 69 Substitute A for 2B3B = 69 Add like terms[tex]\frac{3}{3}[/tex] B = [tex]\frac{69}{3\\} \\[/tex] Divide each side by 3 to isolate the BB= 23In order to solve for A, we simply input B=23 into 2B
A = 2BA = 2(23)A = 46Check:
A + B = 69
46+23 = 69
69 = 69

perform the indicated operation. (4 - 8i)(2 – 5i)
Answer:
-32 - 36i.
Step-by-step explanation:
(4 - 8i)(2 – 5i)
= 4*2 + 4*-5i + 2*-8i + (-8i*-5i)
= 8 - 20i - 16i + 40i^2 Now i^2 = -1 so:

Find the value of x ......
Please answer this question.....
Answer:
x=5/2
Step-by-step explanation:
(2/7)^2x *(2/7)=(2/7)^6
(2/7)^(2x+1)=(2/7)^6
Equate indices
2x+1=6
2x=6-1
2x=5
x=5/2
Answer:
When multiplying the same number, raised to different powers, you carry the number forward so (2/7)^6 is part of the answer.
Now, we have to calculate the exponent.
2x + 1 = 6
So, the answer is x = 2.5 which means
[2/7]^(2*2.5) x [2/7]^1 = [2/7]^6 which equals
[2/7]^5 x [2/7]^1 = [2/7]^6

Jamal recorded three values for measuring water in a graduated cylinder. The
values were 25.85, 24.1, and 24.56. What was the TOTAL amount of water
measured? *
Your answer
Answer:
74.51 mlStep-by-step explanation:
Hello!!!
from the problem statement we can infer that Jamal had a container of water where he fetches from to fill the graduated cylinder.
More so, after some couple of trails he recorded as follows
25.85, 24.1, and 24.56.
Hence the total amount of water he measured out of the container after three trials is
25.85+24.1+24.56= 74.51 ml
(assuming the cylinder is calibrated in ml)
The total volume of water he measures is 74.51 ml

PLZ HELP I will give the brain!! Which of the following statements is true about completing the square? 1. When completing the square, add the square of half the coefficient of x to only the x^2+bx side of the equation. 2. When completing the square, add the square of half the coefficient of x to both sides of the equation. 3. When completing the square, subtract the square of half the coefficient of x from both sides of the equation. 4. When completing the square, add half the coefficient of x to both sides of the equation.
Answer:
Option 2
Step-by-step explanation:
When completing the square, you have to find the number that will allow you to find the perfect square trinomials and when you factor that it should get the form a^2 + 2ab + b^2 and if a is equal to 1, then to find b, you have to take the half of the coefficient and square it because of the equation, and to maintain a balanced equation, you have to add it to both sides (same to both sides)

True or false: equilateral triangles can be classified as acute right or obtuse
Answer:
False
Step-by-step explanation:
Equilateral triangles can only be acute.
Because a triangle can only have 180 degrees in angles, in an equilateral triangle all angles must be less than 90 degrees since they all measure the same (60 degrees)
I hope this helps!
-TheBusinessMan
Answer: False.
Step-by-step explanation:
All the angles of an equilateral triangle are 60° all less than 90° so only acute is correct.

Verizon offers two billing plans for local calls. Plan 1 charges $30 per month for unlimited calls, and Plan 2 charges $11 per month plus $0.04 per call. For how many monthly calls is Plan 1 more cost effective than Plan 2?
Answer:
Number of monthly calls = 475
Step-by-step explanation:
Given:
Plan 1 = $30 per month unlimited calls
Plan 2 = $11 + $0.04(per call)
Find:
Number of monthly calls, plan 1 better than plan 2
Computation:
Plan 1 (Cost) < Plan 2 (Cost)
30 < 11 + 0.04(x)
19 < 0.04(x)
475 < (x)
Number of monthly calls = 475
