Six less than seven times a number is equal to -20

1 answer:

4 0

Let this number be x.
"Six less than seven times a number is equal to -20" can be represented by the equation 7x - 6 = -20. We need to solve for x.
First, add 6 from each side so we can have the variables on a side and the numbers on the other:
7x - 6 + 6 = -20 + 6
7x = -14
Then, you divide each side by 7 so we can get the variable x alone on a side, and its value on the other side:
(7x)/7 = -14/7
x = -2

You can re-check your answer (very important):
7x - 6 = 7 (-2) - 6 = -14-6 = -20
The answer has been approved.

Hope this Helps! :)

Person A leaves his home to visit his cousin, person B, who lives 243 miles away. He travels at an average rate of 46 miles pe

Korvikt [17]

They meet (or pass) each other two hours after B leaves.

When B starts trip A has already gone 23 miles (46 x 0.5)
This means they are still 220 miles apart.
Their closing speed is 46 + 64 = 110 mph.
They will meet 2 hours after B leaves home. (220 / 110)

A will have travelled 46 x 2.5 = 115 miles and B will have travelled 2 x 64 = 128 miles

If the function graphed is f(x), find f(1). A) -4 B) -1/4 C) 0 D) 4

Sergeeva-Olga [200]

Answer: choice A) -4

-----------------------------------------------

Step 1) Draw a vertical line through 1 on the x axis

Step 2) Mark the point where the vertical line and the blue curve intersect (or cross each other)

Step 3) Draw a horizontal line through the point marked in step 2. Note how this horizontal line goes through -4 on the y axis.

So the point (1,-4) is on the blue curve. This means if x = 1 is the input then y = -4 is the output. Recall that y = f(x). So f(x) = -4 is the output as well when the input is x = 1.

In short, this is why f(1) = -4
