Answer:
(-6,6), (0,12), (4,8)
Step-by-step explanation:
To dilate an object, we need to multiply the x and y values by the given scale factor.
In this case the scale factor is 2 --> 2(x, y)
Before-> After dilation
2(-3,3) = (-6,6)
2(0,6) = (0,12)
2(2,4) = (4,8)
Please leave a 'thanks' if this helps!
Answer:
Both expressions are = to 11 when x is 2.
Therefore, the expressions are equivalent.
1 mile = 5,280 feet
Car + space = 13.5 + 3 = 16.5 feet
5,280 / 16.5 = 320
Answer: 320 cars
Solution:
we are given in the problem that
So far, 18 of the 25 students in your class have turned in field trip permission slips.
we have been asked to find
What percent of your classmates have turned in permission slips?
Required Percentage
Simplify we get
Required Percentage
Hence 72% percent of your classmates have turned in permission slips.

- Solving systems of equations using substitution/elimination
Step-by-step explanation:
<u>Step 1: Define Systems</u>
-4x + 9y = 14
12x - 10y = -8
<u>Step 2: Rewrite Systems</u>
-4x + 9y = 14
- Multiply everything by 3: -12x + 27y = 42
<u>Step 3: Redefine Systems</u>
-12x + 27y = 42
12x - 10y = -8
<u>Step 4: Solve for </u><em><u>y</u></em>
<em>Elimination</em>
- Combine 2 equations: 17y = 34
- Divide 26 on both sides: y = 2
<u>Step 5: Solve for </u><em><u>x</u></em>
- Define equation: 12x - 10y = -8
- Substitute in <em>y</em>: 12x - 10(2) = -8
- Multiply: 12x - 20 = -8
- Isolate <em>x</em> term: 12x = 12
- Isolate <em>x</em>: x = 1
