Answer 1

Answer:

Option D:

Difference between g(x) and f(x) is 44.

Solution:

Let us first write the function of f(x).

Take any two points on the line (0, -1) and (-2, 0).

Here, $x_1=0, y_1=-1, x_2=-2, y_2=0$

Equation of a line:

$$(y-y_1)/(x-x_1) =(y_2-y_1)/(x_2-x_1)$

$$(y-(-1))/(x-0) =(0-(-1))/(-2-0)$

$$(y+1)/(x) =(1)/(-2)$

Do cross multiplication.

-2(y + 1) = x

-2y - 2 = x

Add 2 on both sides.

-2y = x + 2

Divide by -2 on both sides.

$$y=-(1)/(2)x-1$

y = -0.5x - 1

f(x) = -0.5x - 1

At x = 20,

f(20) = -0.5(20) - 1 = -11

g(x) = 1.5x + 3

g(20) = 1.5(20) + 3 = 33

Difference between g(x) and f(x)

= g(20) - f(20)

= 33 - (-11)

= 33 + 11

= 44

Difference between g(x) and f(x) is 44.

Option D is the correct answer.

How do you solve the equation 0.4(2x+0.5)=3[0.2x+(-2)]-4

Answers

0.4(2x+0.5)=3[0.2x+(-2)]-4

0.8x+0.2=0.6x-6-4

0.8x-0.6x=-6-4-0.2

0.2x=-10.2

x=-10.2/0.2

x=-51

$0.4(2x+0.5)=3[0.2x+(-2)]-4$

$0.8x+0.2=0.6x-10$

$0.2x=-10.2$

$x= (-10.2)/(0.2)$

$x=-51$

-15 + 12x = 5x + 7 -3x
SOLVE FOR X

Answers

Answer:

$x = 2.2$

Step-by-step explanation:

$- 15 + 12x = 5x + 7 - 3x \n + 12x - 5x + 3x = 15 + 7 \n 10x = 22 \n (10x)/(10) = (22)/(10) \n x = 2.2$

Answer: $x=(11)/(5)$

Simplify both sides of the equation

$-15+12x=5x+7+-3x$

$12x-15=(5x+-3x)+(7)$ (Combine Like Terms)

$12x-15=2x+7$

Subtract 2x from both sides

$12x-15-2x=2x+7-2x\n10x-15=7$

Divide both sides by 10

$(10x)/(10) =(22)/(10)$

$x=(11)/(5)$

What is 12 divided by 3/4

Answers

12 divided by 3/4 =
16

It is 16 because the reciprocal of 3/4 is 4/3 and 12 as a fraction is 12/1. So 12/1 x 4/3 is 48/3. And if you divide 48 by 3 you will get 16. If you don't get 16 then you did the wrong calculation.

Hope I Helped You!!! :-)

Have A Good Day!!!

it would be 16 as your answer
