Answer:X= 1.84. Y= 3.08
Step-by-step explanation:
-9x+8y =8 ............i
-8x+10y= -16........ii
Multiply equation I by 8
Multiply equation ii by 9
-72x+64y = 64 ..... iii
-72x+90y = 144 ..... iv
Subtract iv from iii
-26y = -80
y= 80/26
y= 3.08
Put the value of y in equation i
-9x+8y =8
-9x+8(3.08) = 8
-9x+24.64 = 8
-9x = 8-24.64
-9x=-16.64
Divide both side by 9
-9x/-9 = -16.64/-9
X= 1.84
For the answer to the question above, your end goal is to have $6,000 total in 12 months. since you have $2400 already you can subtract that from 6,000 leaving you with $3600 over the course of 12 months. since you already put $150 in a month over the course of 12 months you would have $1800 which is only half of the goal of $3600. in order for you to put in $3600, you would have to put an additional 150 in your savings along with your regular 150 making Letter B the answer.
Answer= x²+7x+10
When we want to expand expressions such as this, the FOIL method helps us remember what exactly to do. FOIL stands for
F:First
O:Outer
I:Inner
L:Last
So, given the expression (x+5)(x+2), lets multiply the first two terms.
x*x=x²
now the outer two terms
x*2=2x
now the inner terms
5*x=5x
and the last terms...
5*2=10
When we combine these expressions we get:
x²+7x+10
I think this is what you meant to be answered in your question, if I have been mistaken, just comment and I'll edit my answer....
