Answers

Answer:  x = 480

Steps: x/2.4 + 39 = 239

Subtract 39 from both sides: x/2.4 + 39 - 39 = 239 - 39

Simplify: x/2.4 = 200

Multiply both sides by 2.4: x/2.4  ×  2.4 = 200 ×  2.4

Simplify: x = 480

If f(x) = 3x2 + 2x - 2, find f(8) - f(-5)

Answers

Answer: 143

Step-by-step explanation:

f(8) = 3(8)^2 + 2*8 - 2 = 3*64 + 16 - 2 = 192 + 16 - 2 = 206

f(-5) = 3(-5)^2 + 2*(-5) - 2 = 3*25 + (-10) -2 = 75 - 10 - 2 = 63

f(8) - f(-5) = 206 - 63 = 143

Four students spent $12 on school lunch. At this rate, find the amount 10 students would spend on the same lunch.

Answers

Answer:

it's $30 I just know trust meO_o

Step-by-step explanation:

have an amazing day luv

Answer:

10 students would pay for lunch with $30.

Step-by-step explanation:

This is how I know $30 is the correct answer:

1. To figure out how much money it would cost for 1 student I would take the $12 the four students paid for lunch and divide it by 4 so we would know the exact cost for one students lunch (12/4=3 or $3)

2. Now we know $3 is the cost for 1 student. We can now multiply the $3 by 10 (students) so we can get the cost for 10 lunches (3(10)=30 or $30)

3. We got our final answer of $30=10 students lunches.

[x-1] = [x]

a. all integer values of x
b. all real number values of x
c. only negative values of x
d. only non-integer values of x

Answers

C only negative values of x

The set of numbers best describes the possible values of x in the equation is option c. only negative values of x.

Calculation of the possible values of x;

Since the equation is

x - 1 = x

So, here the x should be canceled out

So, it should be like

0 = -1

Hence, we can say that

The option c is correct,

And, the rest of the options are incorrect.

{3x+3y=−18
find the solution to the systems of equations

Answers

Answer:

Answer=

x=(-2),y=(-4)

and in components form,

(-2,-4)

Step-by-step explanation:

equation1 (-2x+2y=-4)

equation2 (3x+3y=-18)

(times equation 1 by 3 and times equation 2 by 2, to make the y values equal to each other)

E1 (-6x+6y=-12)

E2 (6x+6y=-36)

(subtract both equations from each other)

-6x+6y=-12

-

6x+6y=-36

=(-12x=24)

so, x=24÷-12=-2

(then we sub the value of x into one of the equations- the new one or the old one)

3x+3y=-18

(3×-2)+3y=-18

3y=-18+6=-12

y=-12÷3=-4
