What is the solution of the equation 1.6m - 4.8 = -1.6m

1 answer:

6 0

Solve for m:
1.6 m - 4.8 = -1.6 m

Add 1.6 m to both sides:
1.6 m + 1.6 m - 4.8 = 1.6 m - 1.6 m

1.6 m - 1.6 m = 0:
1.6 m + 1.6 m - 4.8 = 0

1.6 m + 1.6 m = 3.2 m:
3.2 m - 4.8 = 0

Add 4.8 to both sides:
3.2 m + (-4.8 + 4.8) = 4.8

4.8 - 4.8 = 0:
3.2 m = 4.8

Divide both sides of 3.2 m = 4.8 by 3.2:
(3.2 m)/3.2 = 4.8/3.2

3.2/3.2 = 1:
m = 4.8/3.2

4.8/3.2 ≈ 1.5:
Answer: m ≈ 1.5

If the function graphed is f(x), find f(1).

Crazy boy [7]

Locate 1 on the x axis. This is the horizontal number line.

Draw a vertical line through 1 on the x axis. Extend this vertical line as far up and down as you can.

Notice how the vertical line crosses the blue curve. Mark this point. Then draw a horizontal line from this point to the y axis. The horizontal line will touch -4 on the y axis. So that means the point (1,-4) is on the curve.

If the input it is x = 1, then the output is y = -4

So that's why the answer is choice A

Which polynomial is written in ascending order? t2 − t 4 t2 4 − t 4 t2 − t 4 − t t2

butalik [34]

In order to solve this, you have to look at the order for each of the variable terms. In this case t is your variablr
4t0=4 exponent is 0. −t1=−t exponent is 1. t2 exponent is 2. So you order them by exponents from least to greatest (ascending). 4−t+t2
