Answer:
choice 2) x+2y+3 = 7
Step-by-step explanation:
equation to match:
x+2y = 4
add 3 to each side
x+2y+3 = 7 (which is the same as choice 2, x+2y+3 = 7)
There is a really easy way to find this out I can't really help you so if you just look it up on google you should get your awnser
Answer:
<em>x = -3 and y = 0</em>
Step-by-step explanation:
<em>It would be more direct to apply elimination in this problem, rather than substitution:</em>
2x + 6y = -6 ⇒ 2x + 6y = -6 ⇒ 10x = - 30
+ 2(4x - 3y = -12) + 8x - 6y = -24
<em>Now let us solve for x through simply algebra:</em>
10x = -30,
<em>x = -3</em>
<em>Substitute this value of x into the first equation to get the value of y:</em>
2( -3 ) + 6y = -6,
-6 + 6y = -6,
6y = 0,
<em>y = 0</em>
Answer:
The tree is 12 yards tall
Step-by-step explanation:
Answer:
0.10s
Step-by-step explanation:
Given data
DIstance= 6.5ft
velocity = 64 feet per second
with the parameters given above, we can find the time taken as
velocity = distance/time
time= distance/velocity
time= 6.5/64
time= 0.10 seconds
Hence the time the ball took is 0.10s
