Substitute
So, -2x-7 = 3x + 3
+2x. +2x
-7= 5x +3
-5x. -5x
-5x-7= 3
+7. +7
-5x= 10
Divide -5 on both sides and you get x= -2
Then substitute -2 in the first equation
-2(-2)-7
4-7
Y= -3
Answer:
7 Months
Step-by-step explanation:
x=number of months
how much is deducted total=number of months times amount deducted per m onth
amount deducted per month=45
number of months=x
how much deducted total=45x
460-deducted total is more than 100
460-45x>100
solve for x
add 45x to both sides
460>100+45x
subtract 100
360>45x
divide both sides by 45
8>x
answer is 7 months
if he does 8 months, then he will have exatly 100 and 100 is noe more than 100
Answer is (9, 7)
Step by step
Rule: 270 degrees counterclockwise about the origin our point A(x,y) becomes A'(y,-x).
This means, we switch x and y and make x negative.
So
(-7, 9) ➡️ ( 9, 7)
<span>The decrease is 46-35=11
11/46 is approximately 0.23913, or 23.913%
Rounded to the nearest whole percent, this is
24%, so I'd say
B</span>
