- Coordinates (x, y)
- Solving systems of equations by substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
y = 5x
20x - 4y = 0
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em> [2nd Equation]: 20x - 4(5x) = 0
- Multiply: 20x - 20x = 0
- Combine like terms: 0 = 0
Here we see 0 does indeed equal 0.
∴ our systems has an infinite amount of solutions.
Answer:
$15
Step-by-step explanation:
since 50% is in 100% you do
100 - 50 = 50
then you do
50 - 35 = 15
so the answer is $15 i hope it helps
Answer:
Step-by-step explanation:
-5x - 10y = 15
<u>-3x + 10y = 25 </u>+
-8x = 40
x = -5
.
Substitute the value of x to one of equations
-5(-5) - 10y = 15
25 - 10y = 15
-10y = 15 - 25
-10y = -10
y = 1
Answer:
option 4
Step-by-step explanation:
Using the rule of radicals
× 
= 
Given
(2 - 5
) 3
← distribute parenthesis by 3
= 6 - 15
= 6 - 15
= 6 - 15(
× 
)
= 6 - 15(2 )
= 6 - 30
Not defective : 25 - 3 = 22
probability of not defective : 22/25
22/25 × 100% = 88%
