Answer:
D. -2/7
Step-by-step explanation:
Dont quote me on this but i think it is 10 because 86 × 2 is 172 and 297 ÷ 172 is 10 I think
Step-by-step explanation:
then put 1/4 as t into the equations and see, if left and right side are equal. if not, then the answer option is wrong.
and you will see that 2t = 1/2 is the right answer.
because
2×1/4 = 1/2
2/4 = 1/2
correct.
Answer:
x=4
Step-by-step explanation:
distribute 5 into (12+5x)
60+25x=20+35x
subtract 35x on both sides
60+25x-35x=20
60-10x=20
subtract 60 on both sides
-10x=-40
divide both sides by -10
x=4

Answer:
Step-by-step explanation:
First let us determine the perpendicular line by remembering that a perpendicular line that intersects with the current line must have the opposite reciprocal slope as it. Meaning... the current slope is -1/2 and the opposite reciprocal is +2 or 2.
To clarify...
*opposite= the opposite sign ex. the opposite of +3 is -3 and the opposite of -1 is +1
*reciprocal=put simply, the reciprocal is the flipped version of the current number ex. the reciprocal of 1/2 is 2/1 or 2 and the reciprocal of 3 or 3/1 is 1/3
After we determine the slope of the perpendicular line, we are also know the point it must pass through.
Given that, we can find the equation.
Using y=mx+b
Plug in known varibles
y=-5
x=-4
m=2
b=?
-5=2(-4)+b
b=3
So now that we have b, we can put the equation in standard form.
y=2x+3
