Answer: -6 = x
Step-by-step explanation: Start by distributing through the parentheses
on each side of the equation to get 5x - 40 = 7x - 28.
Now move your x's to the right and
numbers to the right and you get -12 = 2x.
Divide both sides by 2 and -6 = x
Answer:
x=2
Step-by-step explanation:
We will use the secant-secant Formula:
(whole secant) x (external part) = (whole secant) x (external part)
(1+x+4) * (x+4) = (11+x+1) * (x+1)
Combine like terms
(x+5) (x+4) = (x+12) (x+1)
FOIL
x^2 + 4x+5x + 20 = x^2 + x+ 12x + 12
Combine like terms
x^2 + 9 x + 20 = x^2 + 13 x + 12
Bring everything to the left
x^2 + 9 x + 20- (x^2 + 13 x + 12) = x^2 + 13 x + 12-( x^2 + 13 x + 12)
x^2 + 9 x + 20- (x^2 + 13 x + 12) =0
Distribute the minus sign
x^2 + 9 x + 20- x^2 - 13 x - 12 =0
Combine like terms
-4x +8 = 0
Subtract 8 from each side
-4x+8-8=0-8
-4x=-8
Divide each side by -4
-4x/-4 = -8/-4
x=2
<u>Answer:</u>
The correct answer option is (5, -6).
<u>Step-by-step explanation:</u>
We know that the following are the coordinates of a point:
If this point is reflected through y axis, we are to find the coordinates of its image?
If a point is reflected through y-axis, the sign of the x coordinate is changed so we get:
(5, -6)
Answer:
1/30=x/180
Step-by-step explanation:
The way that Ronnie wrote his proportion is wrong since 180/x is saying that he will miss 180 days of school. The fraction 1/30 means that he would miss 1 day out of 30 days, which is correct. But the fraction 180/x would mean that he is missing 180 days of school, which is wrong.
Solving:
1/30=x/180
180/30=6
1 x 6 = 6 days
He will miss 6 days of school in 180 days.
