Mathematics
1 answer:
Morgarella [4.7K]3 years ago
8 0

Answer:

well

Step-by-step explanation:

3 times 15 is 45

then 3 times negative x is -3x

so 45 - 3x = 2x

3 x moved to the other side turns positive

so you have

5x = 45

45÷5

x = 9

David & Brad are competing in a 20-mile bicycle race. David rides 6.2 miles in 1/4 hour. Brad rides 11.9 miles in 1/2 hour.
Elodia [21]
David will finish first, because if you divide Brad's miles by 2 to his miles in a 1/4 of an hour are 5.95 miles. This means David went 6.2 miles in the same time that Brad went 5.95. Therefore, David will finish first.

Juliette [100K]
Answer : 6x^5 + 6x^2 - 5

Combine the like terms :
4x^5 + 2x^5 = 6x^5
3x^2 + 3x^2 = 6x^2
-6 + 1 = -5

Put into descending order.

Simplify the expression: -x +5 -13 + 12x
nexus9112 [7]

Answer:

x=\frac{8}{11}

Step-by-step explanation:

Given:

-x +5 -13 + 12x

To solve the expression, equating it to zero to write it in standard form.

      -x +5 -13 + 12x=0

Taking the terms of 'x' to one side and the constants to other side:

          -x  + 12x=-5 +13

                    11x=8\\

                      x=\frac{8}{11}

On simplification of the expression the value of 'x' is

                              x=\frac{8}{11}

How do I get the value of a function?
Len [333]

Answer: f(x)=mx+b

f(x)=x+7

if x=2 then

f(2)=2+7=9

A function is linear if it can be defined by

f(x)=mx+b

f(x) is the value of the function.

m is the slope of the line.

b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.

x is the value of the x-coordinate.
