X = 3 and y = -3/2
if you substitute 1/2x -3 in place of y in the first equation, it is pretty easily found
ok so here we go:
1) or
2 ) so the answer is (0, -4) or -4
3) y=
4) y=[tex]\frac{3}{2}x+1[tex] so the answer is (0, 1) or 1
Answer:
because they are traveling towards each other, you can add their speeds together to make 12.5
you divide 50/12.5 to get 4
they will hit in 4 hours
Step-by-step explanation:
Answer:9x1016
Step-by-step explanation:
when adding or subtracting in standard form (aka scientific notation), the powers of 10 need to be the same. If they are just add the numbers and keep the same power of 10
#2xx10^(16)+7xx10^(16)
= ( 2 + 7 ) × 10 16
9 × 10 16
Answer:
Step-by-step explanation:
2x-4=x+10
2x-x-4=x-x+10
x-4=10
x-4+4=10+4
x=14
Check answer by substitution for x
2x-4=x+10
2(14)-4=14+10
28-4=24
24=24
The answer is x=14
