Answer:
x = -4
Step-by-step explanation:
x + 4 = -x - 4
adding both side with x
x + x + 4 = x - x - 4
2x + 4 = -4
give both side (-4)
2x + 4 - 4 = -4 - 4
2x = -8
x = -8/2 = -4

PLEASE HURRY Find the midpoints between points C (7, -9) and D (3, 5).
Answer:
(5,-2)
Step-by-step explanation:
Midpoint formula
If we have coordinates (x₁,y₁) and (x₂,y₂), then the midpoint of these coordinates is determined by (x₁ + x₂)/2, (y₁ + y₂)/2. This forms a new coordinate you can call (x₃,y₃). The midpoint calculator will solve this instantaneously if you input the coordinates. Follow the steps above if calculating by hand.
For small numbers, it's easy to calculate the midpoint by hand, but with larger and decimal values, the calculator is the simplest and most convenient way to calculate the midpoint.
Answer:
Midpoint=(5,−2)Step-by-step explanation:
Midpoint formula
m=((x1+x2)/2,(y1+y2)/2
so lets plug in
((7+3)/2,(-9+5)/2)
(10/2),(-4/2)
(5,−2)

Answer:
9
Step-by-step explanation:
150/2 = 75
72/8=9
Answer:
v is 9 degrees
Step-by-step explanation:
The 2 angles are supplementary angles
Therefore,
8v + 3 + 105 = 180 (supplementary angles add up to 180 degress/straight line)
8v = 180 - 105 - 3
8v = 75 - 3
8v = 72
v = 72/8
v = 9 degrees

Diego collected x kg of recycling. Lin collected 2/5 more than that. [ Select ] Lin biked x km. Diego biked 3/10 less than that. y = 10/3x Diego read for x minutes. Lin read 4/7 of that. y = 7/4x
I assume you want to mathematically represent the above
Answer and explanation:
If Diego collected x kg of recycling and Lin collected 2/5 more than what Diego collected, then it would be represented mathematically thus:
Diego = x
Lin = x +2/5 of x= x+2/5x
if Lin biked x km and Diego biked 3/10km less than Lin, then we would represent this thus:
Lin=x
Diego= x-3/10 of x= x-3/10x
If Diego reads for x minutes and Lin reads 4/7 of what Diego read, then mathematically we represent this thus:
Diego=x
Lin =4/7 of x = 4/7x

Which equation has no solution?
A. 13y + 2 - 2y = 10y + 3 - y
B. 9(3y + 7) - 2 = 3(-9y + 9)
C. 32.1y + 3.1 + 2.4y - 8.2 = 34.5y - 5.1
D. 5(2.2y + 3.4) = 5(y - 2) + 6y
Answer:
D
Step-by-step explanation:
Option D is the only equation where the y-term gets eliminated upon simplifying
11y + 17 = 5y - 10 + 6y
11y + 17 ≠ 11y - 10

Horse Of Course sells "Juan the horse" t-shirts for $23. Due to increased popularity, the store will raise the price by 8%. What will be the new price of the t-shirt?
Answer:
the new price of the t-shirt is $24.84
Step-by-step explanation:
The computation of the new price of the t-shirt is shown below
= Price of the t-shirt × (1 + increased percentage)
= $23 × (1 + 0.08)
= $23 × 1.08
= $24.84
Hence, the new price of the t-shirt is $24.84
We simply applied the above formula so that the correct value could come

Step-by-step explanation:
20x² = y - 24
y = 20x² + 24
For y to have the least possible value, x² have to be the least possible, which is 0.
Since -3 <= x <= 2 includes x = 0, this is allowed.
Hence least possible value of y
= 20(0)² + 24 = 24.
Answer:
24
Step-by-step explanation:
-3---> 20(-3)^2=y-24 ----> y=204
-2---> 20(-2)^2=y-24 ----> y=104
-1---> 20(-1)^2=y-24 ----> y=44
0---> 20(0)=y-24 ----> y=24
1---> 20(1)^2=y-24 ----> y=44
2---> 20(2)^2=y-24 ----> y=104
Please provide an explanation, thank you!

someone help ASAP !! algebra II
Answer:
C
Step-by-step explanation:
Given y = f(x) then y = f(x + a) is a horizontal translation of f(x)
• If a > 0 then a shift to the left of a units
• If a < 0 then a shift to the right of a units
Thus (x - 5)² is a shift to the right of 5 units
Given y = f(x) then y = f(x) + c is a vertical translation of f(x)
• If c > 0 then a shift up of c units
• If c < 0 then a shift down of c units
Thus
y = (x - 5)² + 6
is the graph of y = x² translated 6 units up and 5 units to the right → C
daniel has read 40% of a book. He has more 36 pages to finish. How many pages are there in the book?
Answer:
60 Pages.
Step-by-step explanation:
Using the given information, we can figure out that the remaining 36 pages are 60% of the book.
This is because 100% (whole book) - 40% (what you already read)= 60%= the remaining 36 pages
We can set up a problem to find 36 pages out of how many total pages is equal to 60%
(36/x) x 100 = 60%
=3600/60
=60 pages.
We can check our work by saying checking that 40% of 60 is 24, and 24+36 is 60 pages.

1. A term that is a known number without variables. is called?
2. A term that includes a variable. is called?
Answer:
Constants are the terms in the algebraic expression that contain only numbers. That is, they're the terms without variables. We call them constants because their value never changes, since there are no variables in the term that can change its value.
An algebraic expression is one or more algebraic terms in a phrase. It can include variables, constants, and operating symbols, such as plus and minus signs.
