Answer:

B

Step-by-step explanation:

The point slope form of a line is (y-y_1)=m(x-x_1) where x_1=-3\\y_1=7. We can find the slope which is perpendicular to the slope of 4 in the equation y=4(x-10). Perpendicular slope is the negative reciprocal which is -1/4.

We write  

(y-7)=-\frac{1}{4}(x--3)\\(y-7)=-\frac{1}{4}(x+3)

I need help now I don't get this
Darina [25.2K]
The answer is $1.80.  You would take 25% of 3, which is 75, and subtract it from 3.  That leaves you with $2.25, which you take 20% off, which is 0.45, and subtract that from 2.25.  That leaves you with a grand total of $1.80.  Hope that this helped!

Remove parentheses and simplify 7a+6b-4 (3a-3b)
Varvara68 [4.7K]
Normally, you would do whatever is inside of the parenthesees first then do the rest but we cant get any further so we remove the parenthasees by distrubtion

7a+6b-4(3a-3b)
-4(3a-3b)
a(b+c)=(ab)+(ac)
-4(3a-3b)=-12a-(-12b)

7a+6b-12a+12b
7a-12a+6b+12b
-5a+18b
that's the asnwer
