(4x+2)=102+44 solve for x

Answers

Solution:(4x + 2) = 102 + 44or, 4x = 102 + 44 - 2or, 4x = 144or, x = 144 ÷ 4or, x = 36Answer:

x = 36

4x + 2 = 102 +44
4x+2 = 146
(4x+2) + (-2) = 146 + (-2)
x=36

Evaluate the function at x = -3.

Answers

Answer:

hold on

Step-by-step explanation:

Given the function, p(x) = 4x^3 + 2x^2 - 3x + 2:

We can substitute the value of x = -3 as input into the given function:

p(-3) = 4x^3 + 2x^2 - 3x + 2

p(-3) = 4(-3)^3 + 2(-3)^2 - 3(-3) + 2

p(-3) = 4(-27) + 2(9) - 3(-3) + 2

p(-3) = -108+ 18 - (-9) + 2

p(-3) = -90 + 9 + 2

p(-3) = -81 + 2

p(-3) = -79

Answers

Answer:

Step 89-46=43

Answer:

43 apples

Step-by-step explanation:

89-46=43

If you need to check you could do the opposite:

46+43=89

Since that checks out you know the answer would be 43.

Solve the inequality for x
12x>9(2x-3)-15

Answers

Step-by-step explanation:

12x > 9(2x - 3) - 15

12x > 18x - 27 - 15

12x > 18x - 42

42 > 6x

7 > x

so, this is true for all values < 7

so, x is in (-infinity, 7)

both ends but included - therefore the round brackets.

Can someone tell me what the answers are to each question. I did some of them but I would like to see if they’re also right.

Answers

1) r(x) = 18x
2) c(x) = 4.50x + 30,000 because it costs them 4.50 for each slipper made plus the annual cost of 30,000. It doesn’t ask for how much they earned, just the costs.
3) p(x) = 18x - 4.50x - 30,000, they gain 18$ per slippers sold, lost 4.50 per slippers sold, and lost 30,000 from the annual fee. It can be simplified down to p(x) = 13.5x - 30000
4) loss of 3000$, substitute 2000 for x for the equation and solve
5) 172,500, same as the last question but substitute 15,000
6) p(x) = 19x - 5.25 - 30,000

In 20 seconds, a roller coaster goes up a 100-meter hill, then down 72 meters, and then back up a 48-meter rise. What integer represents the vertical change from the start of the ride for the coaster after the 20 seconds?

Answers

The question is an illustration of arithmetic operations.

The integer that represents the vertical rise is 76

Upward movements are represented with positive, while downward movements are represented with negative.

So, the given parameters are:

[tex]Up = 100m[/tex]

[tex]Down = -72m[/tex]

[tex]Up= 48m[/tex]

The vertical rise is:

[tex]Rise = Up_1 + Down + Up_2[/tex]

So, we have:

[tex]Rise = 100m -72m +48m[/tex]

[tex]Rise = 76m[/tex]

Hence, the integer that represents the vertical rise is 76

Answer:

Step-by-step explanation:

For number 8, to start,:

[tex]\frac{x}{4}[/tex] - 1 = 1

the first step is to add 1 to both sides of the equation; then, simplify.

[tex]\frac{x}{4}[/tex] - 1 = 1

   +1    +1

----------------

next, the -1 and +1 will cancel.

[tex]\frac{x}{4}[/tex] = 2

the last step is to multiply both sides of the equation by 4.

4 · [tex]\frac{x}{4}[/tex] = 2 · 4

simplify; the 4s cancel out on the left side.

x = 8

**************************************************

For number 9, :

9 = 6 + [tex]\frac{x}{7}[/tex]

like in number 8, the first step is to subtract 6 from both sides of the equation; also, a helpful tip you can use is move the 9 to the right side; speaking personally, it often helps make things visually easier to work out. you would then rewrite the equation like: 6 + [tex]\frac{x}{7}[/tex] = 9

6 + [tex]\frac{x}{7}[/tex] = 9

now, we'd subtract 6 from both sides.

6 + [tex]\frac{x}{7}[/tex] = 9

-6         -6

-----------------

next, the 6 and -6 will cancel.

[tex]\frac{x}{7}[/tex] = 3

the last step is to multiply both sides of the equation by 7.

7 · [tex]\frac{x}{7}[/tex] = 3 · 7

simplify; the 7s cancel out on the left side.
