Answer:
2) (3,-2)
Step-by-step explanation:
the solution is where the lines intersect. they intersect at one point because this function is linear. they intersect at the point (3,-2)
Answer:
-21
Step-by-step explanation:
I assume this is a 2 by 2 matrix.
determinant = -5 * 4 - 1 * 1 = -20 - 1 = -21
Step-by-step explanation:
3a^2+24a+45=0
×3/3( first ×3)
9a^2+24(3a)+135=0
(3a+15)(3a+9)=0
now /3
3(a+5)(a+3)
a=-5✓
a=-3✓
2c -7 >= 9
2c >= 16
c >= 8
5d + 7 <= 32
5d <= 25
d <= 5
normal arthematic except diving over -1 or flipping (taking inverse -1) flips the operator
Answer:
-34 -7a
Step-by-step explanation:
–34–23a+16a
Combine like terms
