Answer:
b=-11
Step-by-step explanation:
I assume you are looking to solve for the value of b.
<u>3(b+2)</u> x <u>2</u>= <u>4b-10</u>
2 2 4
<u>6(b+2)</u> = <u>4b-10</u>
4 4
x 4 x4
6(b+2) = 4b-10
6b+12=4b-10
-4b -4b
2b+12=-10
-12 -12
<u>2b</u>=<u>-22</u>
2 2
b=-11
Answer:
a=-2
b=4
c=-3
Step-by-step explanation:
You just compare -2x^2+4x-3=0 to
ax^2+bx+c=0
There is really no work here.
Answer:
2x + 4y = 4
-8x + 8y = -16.
Step-by-step explanation:
We can find an equivalent system by multiply the 2 equations by 2.
x + 2y = 2 multiplied by 2 is 2x + 4y = 4.
Step-by-step explanation:
-7x + 2y = 18
6x + 6y = 0
21x - 6y = - 54
6x + 6y = 0
27x = -54
x = -2
6(-2) + 6y = 0
-12 + 6y = 0
6y = 12
y = 2
(-2,2)
Answer:
C is the answer here
because here initially zero then increased and then decreased
