Answer:
x = 9
Step-by-step explanation:
For the lines to be parallel, then
9x + 8 and 15x - 46 are alternate angles and congruent, thus
15x - 46 = 9x + 8 ( subtract 9x from both sides )
6x - 46 = 8 ( add 46 to both sides )
6x = 54 ( divide both sides by 6 )
x = 9
The equation x=2t-1 represent the x-coordinate. To get the value of x, substitute t with -1.
That is: x = 2(-1) - 1
= -2-1
= -3
Likewise, the equation y=t∧-3 represent the y-coordinate. Substituting t with -1,
y = (-1)∧-3
= -1
The point that correspond to t=-1 is (-3,-1).
Answer:
d it is D
Step-by-step explanation:
Answer:
21 feet and 7 inches
Step-by-step explanation:
I multiplied 6 by 12 twice to find out how many inches she needs for the sides of the ladder which got me 154 then i multiplied 7 by 15 which got me 105 then i added the two products together and got 259 then i divided 259 by 12 to find out how many feet were in 259 inches which got me 21 with a reminder of 7
Therefore, the answer is 21 feet and 7 inches
Let x = the unknown number to get x = 6
