Answer:
x= -5 or -1
Step-by-step explanation:
subst y = -x + 5 into y = x^2 + 5x + 10
-x +5 = x^2 + 5x +10
x^2 +6x +5 = 0
(x+5)(x+1)=0
x= -5 or -1
12/21 in its simplest form is 4/7.
To find this out we need to divide the numerator and denominator by the GCF of 12 and 21 which is 3.
12/21
12 ÷ 3 = 4
21 ÷ 3 = 7
4/7
12/21 in its simplest form is 4/7.
12/21 = 4/7
I want to say 5 but I'm not sure
Answer:
65 degrees
Step-by-step explanation:
Break the parallelogram up into two triangles. Angle E is 70 degrees and 45 degrees because of the property of equal opposite angles. So E 45 degrees Y 70 degrees and if you add the two up you get 115 degrees. There are 180 degrees in a triangle, so 180-115=65.
Answer:
You can say there is no solution for a system of linear equation when the graphs are PARALLEL to each other.
ONE solution: when both lines intersect at one point
INFINITE solution: when the line goes on forever
NO solution: is when the lines are parallel to each other.
