How do you get -3/4 y to y by itself if you have the problem: -3/4 y = -1/2 x - 2?
Answer:
Hi there!
Your answer is:
To isolate y that has a fraction, multiply by the inverse of the fraction! This is called the multiplicative inverse property!!
Y is equal to:
y = 2/3 x + 2 & 2/3
Step-by-step explanation:
Heres a break down of how to do this:
-3/4y = -1/2x -2
Multiply both sides by -4/3!
-4/3 × -3/4 = -12/12 (which equals -1!!)
y = -4/3 (-1/2x -2)
y = 2/3 x + 2 & 2/3
I hope this helps you! If you need clarification let me know!

every whole number is positive true or false?
Answer:
true
Step-by-step explanation:
4−0.25g+0.5h4-0.25g+0.5h 4−0.25g+0.5h 4, minus, 0, point, 25, g, plus, 0, point, 5, h when g=10g=10 g=10 g, equals, 10 and h=5h=5 h=5 h, equals, 5 .
Answer:
The value of the expression is 4
Step-by-step explanation:
Given:
Evaluate 4 - 0.25g + 0.5h
When g = 10 and h = 5
Substitute the value of g and h into the expression
4 - 0.25g + 0.5h
= 4 - 0.25(10) + 0.5(5)
= 4 - 2.5 + 2.5
= 4
Therefore, the value of the expression is 4

Ryan can text 22 words in 4 minutes. At this rate, how many words could he text in 12 minutes? Fill out the table of equivalent ratios until you have found the value of x.
SW=2x+y, WC= x-2y, W is the midpoint of SC, and SC=20, find the values of x and y.
Answer:
[tex]x= 6[/tex]
[tex]y = -2[/tex]
Step-by-step explanation:
Given
[tex]SW = 2x + y[/tex]
[tex]WC = x - 2y[/tex]
[tex]SC = 20[/tex]
Required
Determine x and y
Since W is the midpoint;
[tex]SW = WC = \frac{1}{2} * SC[/tex]
[tex]SW = WC = \frac{1}{2} * 20[/tex]
[tex]SW = WC = 10[/tex]
Substitute 10 for SW and WC
[tex]2x + y = 10[/tex] --- (1)
[tex]x - 2y = 10[/tex] ---- (2)
Make x the subject in (2)
[tex]x = 10 + 2y[/tex]
Substitute [tex]x = 10 + 2y[/tex] in (1)
[tex]2(10 + 2y) + y = 10[/tex]
[tex]20 + 4y + y = 10[/tex]
[tex]20 + 5y = 10[/tex]
Solve for 5y
[tex]5y = 10 - 20[/tex]
[tex]5y = -10[/tex]
Solve for y
[tex]y = -10/5[/tex]
[tex]y = -2[/tex]
Recall that [tex]x = 10 + 2y[/tex]
[tex]x = 10 + 2(-2)[/tex]
[tex]x = 10 -4[/tex]
[tex]x= 6[/tex]

Find the midpoint of the line segment with the given endpoints A (-5,9), B (5,7)
A.(-5,1)
B.(2,6)
C.(0,8)
D.(15,5)
Answer:
The answer is option CStep-by-step explanation:
The midpoint M of two endpoints of a line segment can be found by using the formula
[tex]M = ( \frac{x1 + x2}{2} , \: \frac{y1 + y2}{2} )[/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
A (-5,9), B (5,7)
The midpoint is
[tex]M = ( \frac{ - 5 + 5}{2} \: , \: \frac{9 + 7}{2} ) \\ = ( \frac{0}{2} \: , \: \frac{16}{2} )[/tex]
We have the final answer as
( 0 , 8)Hope this helps you
Express each product in the simplest form. A. wx/6 B. wx/3 C. 2/3/wx D. wx
Answer:
A) [tex]\frac{wx}{6}[/tex]
Step-by-step explanation:

Mr. Laschober's Claim
"I believe that there exists integers
that cannot be expressed as a
sum of consecutive integers."
- Mr. Laschober
How can I prove this wrong?
Answer:
Ok, if we start with a number n, then we can write the consecutive numbers of n as:
n + 1
n + 2
n + 3..
etc.
Now, suppose that we have an integer x, and we want to write it as a sum of consecutive numbers.
There is a really trivial way.
We know that x + 0 = x.
now, we can write:
0 = (x - 1) + (x - 2) + ... + 1 + 0 + (-1) + (-2) + ..... + (-x + 2) + (x - 1)
Then we wrote zero as a sum of consecutive numbers.
Now we can write:
x = x + 0 = x + (x - 1) + (x - 2) + .... + 1 + 0 - 1 - 2 - ... - (x - 1) = x
Then we show that for any integer x, we can write it as a sum of consecutive integers.
Then it must work for all the integers x, then we prove that all the integers can be written as a sum of consecutive integers.
