Step-by-step explanation:
2x + 5y = -24
3x - 5y = 14
Solve by elimination
y and x
Answer:
x = -2
y = -4
Step-by-step explanation:
The way systems of equations work is that you have to substitute to solve for a variable *(only one of the 2 ways to figure this out)*
so, we will use addition property of equality in a form to add the two equations together, since +5y and -5y added together will cancel out.
that would leave
5x = -10
divide both sides by 5
x = -2
Now that we know x = -2, we can plug in -2 into one of the equations to find y.
2 ( -2) + 5y = -24
-4 + 5y = -24
-4 + 4 + 5y = -24 + 4
5y = -20
y = -4
x = -2
y = -4
Can y'all help me with this

how to change .75 to a percentage NOW
Answer:
Move the decimal place over to the left two spaces
.75--> 7.5--> 75%
and reverse
75%--> 7.5--> .75
Step-by-step explanation:
brainliest plz
Answer:
75%
Step-by-step explanation:
"Percent" means "per 100" or "over 100". So, to convert 0.75 to percent we rewrite 0.75 in terms of "per 100" or over 100.
Multiply 0.75 by 100/100. Since 100/100 = 1, we are only multiplying by 1 and not changing the value of our number.
0.75 100 75
-------- x -------- = -------- which equals to 75%
1 100 100

PLS HELP THE PICTURE IS DOWN BELOW
Answer:
4
Step-by-step explanation:
Normally you would have to figure out the distance of the x- and y-components and use the Pythagorean Theorem; however, because the y-coordinates of both points are the same, you only need the x-coordinates.
You have the first point back 3, and the second point forward 1.
So starting at -3, you move 4 points to get to 1.
((-3 to -2 (1), -2 to -1 (2), -1 to 0 (3), 0 to 1 (4)))
Find the distance AB. Give your answers correct to 1 decimal place
Answer:
AB= 8.1
AB=7.8
Step-by-step explanation:
[tex]ab = \sqrt{ {(8 - 1)}^{2} + {(6 - 2)}^{2} } [/tex]
[tex] = \sqrt{ {7}^{2} + {4}^{2} } = \sqrt{49 + 16} [/tex]
[tex] = \sqrt{65} = 8.1[/tex]
[tex]ab = \sqrt{ {(6 - 1)}^{2} + {(2 - 8)}^{2} } [/tex]
[tex]= \sqrt{ {5}^{2} + { ( - 6)}^{2} } = \sqrt{25 + 36} [/tex]
[tex] = \sqrt{61} = 7.8[/tex]
