100 + x
Step-by-step explanation:
If Peter has an initial 100$, and his mom gives him an additional x$, then we can simply write the total amount in an expression using addition as such:
100 + x
So Peter now has 100 + x amount of dollars.

Answer:
Dear mcdeagon,
Answer to your query is provided below:
Magnitude of -2a-3b = -18i-6j
Step-by-step explanation:
When a = 3i+9j and b = 4i-6j
Magnitude of -2a-3b will be calculated by putting value of a and b
So, -2a-3b = -2(3i+9j)-3(4i-6j)
= -6i-18j-12i+12j = -18i-6j
Answer:
15
-40
Step-by-step explanation:
A negative times a negative is a positive.
A negative times a positive is a negative.
When a line is perpendicular to another line with a given slope, you can use the given slope of the original line to find the slope of the perpendicular line. All you need to do is flip the reciprocals. Since the slope of the given line is -1/8x, the slope of the perpendicular line would be 8x. Since there is only one line with a slope of 8x in the answer choices, your answer would be:
a. y=8x+13
Hope this helps!
