Here is all I got for you. From the starting expression to the simplest one.
t^2 + 4tv + 4^2 =
t^2 + 4tv + 16 =
t(t + 4v) + 16
Answer:
The slope would also be -4.
Step-by-step explanation:
This is because parallel lines have the exact same slope. Since these two lines are parallel and the first has a slope of -4, the second must as well.
Answer:
(4, 7 )
Step-by-step explanation:
y = 3x - 5 → (1)
y = 
x + 5 ( multiply through by 2 to clear the fraction )
2y = x + 10 → (2)
Substitute y = 3x - 5 into (2)
2(3x - 5) = x + 10 ← distribute parenthesis on left side
6x - 10 = x + 10 ( subtract x from both sides )
5x - 10 = 10 ( add 10 to both sides )
5x = 20 ( divide both sides by 5 )
x = 4
Substitute x = 4 into (1) and evaluate for y
y = 3(4) - 5 = 12 - 5 = 7
solution is (4, 7 )
Answer:
B. 498
Step-by-step explanation:
First, you figure out what 12 x 40 equal: 12 x 40 = 480.
Then, You figure out what 12 x 1.5 equals: 12 x 1.5 = 18.
Finally, you just add the two together: 480 + 18 = 498.
Hope this helps!!!
