5r+1w=80
System of equations :)
Answer:
this trinomial is prime, and cannot be factored.
Step-by-step explanation:
when expanding the equation, you multiply the last term by the first term's coefficient, and then find two factors that multiply to that product, and sum to the middle coefficient.
1 * 19 = 19
there are no factors that will multiply to 19 and sum to 11. thus, this polynomial is prime.
Answer:
<u>x = -8</u>
4x + 8 = 2x - 8
3x + 4 = 2x - 4
2x + 16 = x + 8
x - 1 = 2x + 7
17x + 36 = 16x + 28
13x + 2 = 12x + 11
.......
(this is infinite)
As long as it cancels out to x = -8
Answer:
False
Step-by-step explanation:
The triangles are similar because the angles are the same
We know nothing about the side lengths, so we can say nothing about concurrency. They may or may not be congruent.
Answer:
Step-by-step explanation:
The line has a slope of -1/3. For lines to be perpendicular there product must equal negative 1
m1(m2)=-1
-m/3=-1
m=3
So we know our line has a slope of three so
y=3x+b, we can solve for the y intercept, b, using point (-2,8)
8=3(-2)+b
8=-6+b
b=14, so our line is
y=3x+14
