Answer:
answer is option B
Step-by-step explanation:
ok the equation is 2/3 x +9 = 15
if we substract 9 from both sides it becomes, 2/3x +9-9 = 15-9.
2/3x = 6
now if we multiply both sides by the reciprocal of 2/3 ( reciprocal means flip it for example receprocal or 2/3 is 3/2)
we multiply both side by reciprocal ie,
2/3 x 3/2 which is 1 because the 3 on the numerator cancels with the 3 on the deniy and the 2 on the numerator cancels with 2 on the denominator. then you are left with only x on the left side.
x = 6 x 3/2 = 18/2 = 9.
Answer:
V=-11
Step-by-step explanation:
V + 6/2 = -8
You simplify the 6/2 <em>PEMDAS</em>
V + 3 = -8
You subtract 3 from both sides <em>PEMDAS/isolate the variable/combine like terms</em>
V = -11
Answer:
The given points ( 4 , 1 ) is <u>not</u> a solution of line y = - x + 3 .
Step-by-step explanation:
Given line equation as :
y = - x + 3
<u>Now to get the solutions of line equation , we have to substitute the x-coordinate value and y-coordinate value in the given line equation , and if the coordinates satisfy the equation, then this must be the solution .</u>
So , for points ( 4 , 1 )
Here x-coordinate is 4
And y-coordinate is 1
∴ For x = 4 , The line is y = - 4 + 3
I.e y = - 1
And For y = 1 , The line is 1 = - x + 3
I.e x = 3 - 1 = 2
So, <u>We have check both the coordinates but they do not satisfy the line equation </u>
Hence The given points ( 4 , 1 ) is not a solution of line y = - x + 3 . Answer
