Answer:

Step-by-step explanation:
For finding the system of equations you can use one of two methods. There's the elimination method and also the substitution method. For this I think the best way we could go at solving this is by using the elimination method. Since we can eliminate the 2y. We can then solve for x and then we'll go from there.

Now that we know what x is we can substitute it for one of the equations and then we will be able to solve for y.

So now we have the x and the y and once we place them together we can get the solution of those two equations, and the solution is
.
Answer:
$49
Step-by-step explanation:
<u><em>Method 1</em></u><u><em>:</em></u>
100% - 65% = 35%

y · 100 = 35 · 140
100y = 4900
100y ÷ 100 = 4900 ÷ 100
y = 49
<u><em>Method 2</em></u><u><em>:</em></u>

y · 100 = 65 · 140
100y = 9100
100y ÷ 100 = 9100 ÷ 100
y = 91
$140 - $91 = $49
15 = 2w - 5
15 + 5 = 2w
20 = 2w
20/2 = 2w/2
10 = w
w = 10
Answer:
Slope is -2/7
Step-by-step explanation:
Slope formula is y₂-y₁/x₂-x₁
So...
(x₁,y₁) and (x₂,x₂) →(2,2) and (-5,4)
4-2= 2
-5-2= -7
2/-7
Question:
What is the value of
when x=3 and y=0
Answer:
The answer is zero
Step-by-step explanation:
Given:
x = 3
y = 0

Solution:
Let us first substitute the given values inb the expression
then we get


We also know that anything raised to the power of zero also give zero
then


=> 0
