Answer:

Step-by-step explanation:

f ( x + 1 ) = 3 x ^ { 2 } - 2 x - 5. f ( x + 1) = 3 x 2 − 2 x − 5. Factor the expression by grouping. First, the expression needs to be rewritten as 3x^ {2}+ax+bx-5. To find a and b, set up a system to be solved. Factor the expression by grouping. First, the expression needs to be rewritten as 3 x 2 + a x + b x − 5.

B = P +Prt
8250 = 6000 +6000*r*12.5 . . . . substitute the given information
2250 = 6000*r*12.5 . . . . . . . . . . .subtract 6000

Answer:

1,177.5

Step-by-step explanation:

I have not done this is a while but the formula is v = 3.14 r^2 h

so 3.14 x 5^2 x 15

then 3.14 x 25 x 15

lastly multiply it all to get 1,177.5

5/7 ............. 15/21 NONE OF THESE EQUAL GREATER THAN LESS THAN

sertanlavr [38]

Answer: EQUAL

Step-by-step explanation:

Just as you can do the same thing to both sides of an equation, you can do the same thing to both sides of a fraction. 15 = 5*3 and 21 = 7*3. Thus, 5/7=15/21

Answer:

2x +5y = -15

Step-by-step explanation:

We need to find the slope

m = (y2-y1)/(x2-x1)

= (-7--1)/(10- -5)

= (-7+1)/(10+5)

-6/15

-2/5

The point slope form

Y+7= -2/5 (x - 10).

Distribute

y + 7 = -2/5x + 4

Add 2/5 x to each side

2/5x +y +7 = 4

Subtract 7 from each side

2/5x +y = -3

Multiply each side by 5

5(2/5x +y) = -3*5

2x +5y = -15

This is standard form Ax + By = C where A is a positive integer
