B.2x - 30 = -10
C.4x - 28 - 2x +2 = -10
D.4x - 7 - 2x + 1 = -10
Answers
which is
4x -28 - 2x + 2 = -10
The equation 4(x − 7) −2(x+1) = −10 is equivalent to 4x -28 - 2x + 2 = -10
The correct answer would be an option (C)
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
Given that the equation as
⇒ 4(x − 7) −2(x+1) = −10
We have to open the brackets above and apply the distributive property of multiplication,
⇒ 4x -28 - 2x + 2 = -10
Thus, the equation 4(x − 7) −2(x+1) = −10 is equivalent to 4x -28 - 2x + 2 = -10
So the correct answer would be option (C)

Step-by-step explanation:
Line A is going up so the speed is increasing.
Line B is just a straight line so there is no change.
Line C is going down so the speed is decreasing.
Answer:
Increasing no change decreasing

Step-by-step explanation:
as I put in my comments :
in a coordinate grid the x-axis and the x values go left/right, while the y-axis and y values go up/down.
right and up are the corresponding positive sides, left and down the negative ones.
so, moving 8 units to the right means adding 8 to the x value. moving 2 units up adds 2 to the y value.
so, for (-7, 2) the result is (1, 4).

Pls Someone help me I don't understand math very well can someone help me on how to get the answer for 1/4 x 8 4/9?
Answers
Answer:
2 4/36
Step-by-step explanation:
To do this, multiply the whole number by the denominator and add it to the numerator.
8 x 9 = 72
72 + 4 = 76
76/9
Then multiply across (multiply numerators with numerators; denominators with denominators)
76 x 1 = 76
9 x 4 = 36
76/36 = 2 4/36
____________________________
A faster way to do this is to multiply the whole number by the fraction and then the fraction by the fraction.
1/4 x 8/1 = 8/4 = 2
1/4 x 4/9 = 4/36
= 2 4/36
Answer:
2 1/9
Step-by-step explanation:
Multiplying fractions: Numerator times numerator over denominator times denominator. IF you have a mixed number, convert it into improper fraction, then do numerator times numerator over denominator times denominator.
1/4 x 76/9 (I got 76/9 because the 8 means 8 9/9s, so (8 x 9)=72 plus 4 because 4/9s=76/9)
1/4 x 76/9= 76/36
=38/18
=19/9
=2 1/9

Find The value of H:
S=2πr(r+h)
Answers
Answer:
[S / (2πr)] - r = h
Step-by-step explanation:
You can't solve for H because there isn't a capital H in the equation. However, I'm going to pretend its "h" because that might have been a mistake.
S = 2πr(r + h)
Divide by 2πr to try to isolate h
S / (2πr) = r + h
Subtract r from both sides to get h by itself
[S / (2πr)] - r = h
That is your final answer.
[tex]\\ \rm\Rrightarrow S=2\pir(r+h)[/tex]
[tex]\\ \rm\Rrightarrow r+h=\dfrac{S}{2\pi r}[/tex]
[tex]\\ \rm\Rrightarrow h=\dfrac{S}{2\pi r}-r[/tex]
[tex]\\ \rm\Rightarrow h=\dfrac{S-2\pi r^2}{2\pi r}[/tex]
