ANSWER
EXPLANATION
First equation:
Second equation:
Let us equate the two equations and solve for x.
This implies that;
Group similar terms to obtain:
Simplify:
Divide both sides by 3
Put x=-2 into any of the equations.
I will put x=-2 into the first equation:
This implies that,
He will need 48×2=96 brownies so 96÷16= 6 packages of brownie mix
(1,-10)
the 10 must be negative
reason why the others dont work:
(1,10) too positive, the other two start negative, no way is it going to be way up here
(10,1) still too high
(-1,10) then again, too high
Answer:
y = -2x + 1.
Step-by-step explanation:
2y = x - 1
y = 1/2y - 1/2
If line X is perpendicular to line Y (the line where y = 1/2y - 1/2), the slope will be the negative reciprocal of line Y. That means that there will be a negative sign instead of positive, and the 1/2 will be flipped to become 2/1, which is 2.
So, the slope will be -2.
We now have y = -2x + c.
To find c, simply put in -1 for x and 3 for y.
3 = -2 * -1 + c
c + 2 * 1 = 3
c + 2 = 3
c = 1
So, the equation of the line is y = -2x + 1.
Hope this helps!
If you mean h(4)
h(4)=(4)*2 -5(4)
=8-20
=-12
The answer will be-12
