Answers

Answer 1

Answer:

Step-by-step explanation:

Morning

-5°C

Noon (+3)

-2°C

4pm (+?)

0°C

Equation I used:

(-5) + (3) + x = 0

I'm assuming you're being taught how to work with negative intervals in algebra? Don't worry, that's why you're practising with temperature. Instead of asking online, try using the progress your teacher taught you. If you have notes, look back at them. Practise makes perfect :)

A x = -8
(B) x = -2
C x=3
(D) x = 12
Math

Answers

The answer is D.

The first step is to use the distributive property and turn 5(x-4) into 5x - 20.
You then move the twenty into the right equation by adding 20 to both sides. The final step is to move the 3x into the left equation by subtraction and then dividing both sides by 2 to isolate x. Hope this helped !!

Answer:

D

Step-by-step explanation:

5(x-4) = 3x + 4

5x-20 = 3x + 4

5x-3x-20= 4

2x=4 +20

2x=24

x=12

check answer by inserting 12 for x into original  equation.

5(12-4) = 3(12) +4

Would the simplified version of this be 5x^4+7x?

Answers

Answer:

5x⁴ + 7x or x(5x³ + 7 )

Step-by-step explanation:

Given expression:

        5x⁴ - 7(-x )

To simplify this expression, we have to follow the order of operation PEMDAS;

Parentheses, Exponents, Multiplication, Division, Addition and Subtraction

  5x⁴ - 7(-x ) = 5x⁴ + 7x

               Since x is common to both terms;

                = x(5x³ + 7 )

So the simplified version can be 5x⁴ + 7x or x(5x³ + 7 )

Answer:

y-intercept = (0, 4)

x-intercept = (3/4, 0)

Step-by-step explanation:

1 - Find the slope

[tex]slope = m = \frac{rise}{run} = \frac{y_2~-~y_1}{x_2~-~x_1} = \frac {-11-10}{5-(-2)} = \frac {-21}{7} = -3[/tex]

2 - Plug the slope into y = mx + b and substitute a point into x and y to find the y-intercept, b, by isolating it.

y = mx + b

y = -3x + b

10 = (-3)(-2) + b

10 = 6 + b

-6   -6

4 = b

y-intercept = (0, 4)

3 - Rewrite the completed formula

y = -3x + 4

4 - Substitute 0 in for y to find the x-intercept

0 = -3x + 4

-4          - 4

-4 = -3x

-4/-3 = -3x/-3

A runner saved $25 when he purchased a pair of tennis shoes on sale. If the sale price was 35% off the regular price, what was the regular price of the tennis shoes?

Answers

Given:

Amount saved in sale = $25

Sale price was 35% off the regular price.

To find:

The regular price of the tennis shoes.

Solution:

Let the regular price of the tennis shoes be x.

Sale price was 35% off the regular price.

[tex]Discount=\dfrac{35}{100}x[/tex]

Amount saved in sale = $25

[tex]0.35x=25[/tex]

Divide both sides by 0.35.

[tex]x=\dfrac{25}{0.35}[/tex]

[tex]x=71.42857[/tex]

[tex]x\approx 71.43[/tex]

Therefore, the regular price of the tennis shoes is $71.43.
