$\frac{3-5x}{-4}$

$\frac{3+-5x}{-4}$

$\frac{-5x+3}{-4}$

$\frac{5}{4} x+\frac{-3}{4}$

$\frac{5x-3}{4}$

Step-by-step explanation:

For instance, though not like terms, subtract

5-3/4= 2/4= 1/2

3-5/-4= -2/-4, -ve plus -ve hence +ve

+ve 1/2

They are the same

PLEASE HELP ME 3X+1/14=2X/8 WHAT IS X? EXPLAIN HOW YOU GOT THE ANSWER

balandron [24]

Cross-multiply so that 8(3x + 1) = 14(2x)

Distribute the 8 and 14 into the parentheses:
24x + 8 = 28x

Subtract 24x from both sides:
8 = 4x

Divide both sides by 4:
x = 2

The population of Mexico has been increasing at an annual rate of 1.7%. If the population was 100,350,000 in the year 2000, pred

Svetllana [295]

We can withdraw a equation to give mexico population

P = M.(1 + i)^t

So,

First of all, how many years passed? 2015 - 2000 = 15. Our time is 15, our annual rate is 1,7%, time to calc.

P = 100350000.(1 + 1,7%)^15

1,7% = 0,017

P = 100350000.(1 + 0,017)^15

P = 100350000.(1,017)^15

P = 100350000.1,2876988084901218382866596204289

P = 129220575,43198372647206629291004

Rounding

P = 129,220,575

A rectangular Corn Hole area at the Recreation Center has a width of 5 feet and a length of 10 feet. If

inysia [295]

Answer:

2 feet

Step-by-step explanation:

Let

x ----> the uniform amount added to each side

we know that

The algebraic expression that represent this situation is

$(5+x)(10+x)=84$

solve for x

Apply distributive property

$50+ 5x+10x+x^2=84\\x^2+15x-34=0$

solve the quadratic c equation

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^2+15x-34=0$

$a=1\\b=15\\c=-34$

substitute in the formula

$x=\frac{-15\pm\sqrt{15^{2}-4(1)(-34)}} {2(1)}$

$x=\frac{-15\pm\sqrt{361}} {2}$

$x=\frac{-15\pm19} {2}$

$x=\frac{-15\pm19} {2}=2$

$x=\frac{-15\pm19} {2}=-17$

therefore

The solution is x=2 ft

F(x) = x^2 -7x +14, g(x) = 4x -9 <br><br> Find (g ° f)(x)

adelina 88 [10]

Answer:

Set up the composite result function.

g(F(x)) Evaluate g(x2−7x+14)

by substituting in the value of F into g.

g(x2−7x+14)=4(x2−7x+14)−9

Simplify each term.

g(x2−7x+14)=4x2−28x+56−9

Subtract 9 from 56.

g(x2−7x+14)=4x2−28x+47
