Answer:
They are equal
Step-by-step explanation:
Using the rule of exponents
= 
Given
= 
= 
The exponents of both expression are 8 and therefore equal
Answer:
Step-by-step explanation:
so what you need to do is 112=16m+12b
m=magazines
b=books
Answer:
y = 2x+7
Step-by-step explanation:
y = mx + c
m = slope
c is the y intercept
so
y = 2x+ 7
Recall that the direction of a vector can be seen from its slope, namely b/a.
let's take a peek at a couple of vectors, and multiply them by a scalar of 2.
hmmm say < 3 , 7 > , it has a slope of 7/3, now if we use a scalar of 2
2<3,7> => < 6 , 14 >, now, the slope of that is 14/6 which simplifies to, yeap, you guessed it, to 7/3, no change in the slope.
and say hmmmm < 11 , -2 >, slope of -2/11, let's multiply it by 2
2<11,-2> => <22 , -4 >, slope is -4/22 which simplifies to -2/11.
so, the vector's magnitude gets blown up, but the slope remains the same.
X+10=15
Isolate x by subtracting 10 from both sides
x+10-10=15-10
x=5
Final answer: B
Check by plugging the value in
5+10=15
True
