When you multiply a negative and a positive you will get a negative answer so 3*7 is 21 so -3 * 7 is -21
Answer:
0.7.
Step-by-step explanation:
x^2 = 0.7x
x^2 - 0.7x = 0
x(x - 0.7) = 0
x = 0, 0.7.

Question
Which combination of transformations can you use to show that one shape is congruent to another?
A. dilations and reflections
B. reflections and stretches
C. rotations and translations
D. reflections, dilations, and translations
E. rotations, translations, and dilationsANSWER -
ANSWER -
The correct answer to this is:
ROTATIONS AND TRANSLATIONS
Reflection and rotation can also be used but since their both grouped with dilations, they can't be used. When dilation is used, the size of the shape is changed and congruence won't be possible anymore . That's why the answer is the first option.

Step-by-step explanation:
From the question, we are informed that Tabitha started working at a coffee shop making $8.75 per hour and that every 6 months, she gets a $0.40 cents raise.
a. The formula to represent her hourly wage after each raise would be:
= $8.75 + 0.40m
where m = period of 6 months
b. Find her hourly wage at 3yrs.
First we should note that 3 years = 3 × 12 = 36 months. Therefore, we would have 6 periods in 36 months since there's an increase every 6 months.
Therefore, using the formula
= $8.75 + 0.40m
where m = 6
= $8.75 + 0.40(6)
= $8.75 + $2.40
= $11.15
