Answer:
I think it B but I really don't know cause need like an example
Answer:
y = 3
x = 2
Step-by-step explanation:
-5x + 4y = 2
9x - 4y = 6
Sum both eq.
-5x + 9x = 4x
+4y - 4y = 0
2 + 6 = 8
then:
4x + 0 = 8
4x = 8
x = 8/4
x = 2
from the first eq.
-5x + 4y = 2
-5*2 + 4y = 2
-10 + 4y = 2
4y = 2 + 10
4y = 12
y = 12/4
y = 3
Check:
from the second eq.
9x - 4y = 6
9*2 - 4*3 = 6
18 - 12 = 6
Answer:
C
Step-by-step explanation:
m<2:
180 - 60 - 48 = 72
Vertical angle thm:
m<1 = 48
m<3:
180 - 62 - 48 = 70
Answer:
The answer is B
you should still invest in a calculator (:
