Answer 1

Answer:

[tex]y = \frac{1}{8} x - 3[/tex]

Step-by-step explanation:

Formula for straight lines:

[tex]y = mx + b[/tex]

where m = slope, b = constant

Given:

y-intercept = -3 (0, -3)

m = ⅛

Substitute into formula to find b.

[tex] - 3 = \frac{1}{8} (0) + b \\ - 3 = 0 + b \\ b = - 3[/tex]

Substitute b into original formula

[tex]y = mx + b \\ y = \frac{1}{8} x + ( - 3) \\ y = \frac{1}{8} x - 3[/tex]

Lucy works as a tutor for $7 an hour and as a waitress for $12 an hour. This month, she worked a combined total of 86 hours at her two jobs.
Lett be the number of hours Lucy worked as a tutor this month. Write an expression for the combined total dollar amount she earned this month.

Answers

Answer: 7t + 12(86-t)

==========================================================

Explanation:

t = number of hours she worked as a tutor86-t = number of hours she worked as a waitress

The two expressions mentioned add to 86, to indicate the total number of hours for both jobs combined.

7t = amount earned as a tutor12(86-t) = amount earned as a waitress

We multiply the number of hours by the wage per hour to get the amount earned per job.

Lastly, we add those two subtotals to get the grand total earned

7t + 12(86-t)

Optionally you can distribute the 12 through and combine like terms. I'll leave it like this because I think it's more descriptive to show the two amounts earned from each job.

If you wanted to simplify 7t+12(86-t), then you would get 1032-5t or -5t+1032

A triangle has an area of 16in^2 and a height of 4in. What is the length of the base?

Answers

Answer:

8 inches

Step-by-step explanation:

The area of a triangle is:

a = 1/2 × b × h

b = length of the baseh = height

We can sub in the values we know:

16in² = 1/2 × b × 4in

To find b, we divide both sides by 1/2 and 4in:

16in² ÷ (1/2 × 4in) = b

16in² ÷ 2in = b

b = 8in

Hope this helps!

x=458

Step-by-step explanation:

1729-810=919

919-790=129

810-129=681

681-112=569

112-1=111

569-111= 458 (which is the answer)

Answer:

I get 458, but please check the calculations.

Step-by-step explanation:

See attachment. I worked down the pyramid until I has enough information to calculate x. For example, 919 had to be the difference of (1729 - 810) for a sum of 1729. 129 had to be the difference of (919-790). 681 is the difference of (810 - 129). And so on . . .

You want to save at least $180 to buy a new phone. You already have $65 in your account, and you can save $23 a week from your after-school job. Which inequality can be used to find the minimum number of weeks you need to save before you can purchase the phone?

Answers

Answer: 180≤23x+65

Step-by-step explanation:

p = phone

w = weeks

65 + 23w ≥ 180

If you need it to be solved, the minimum number of weeks goes as shown:

65 + 23w ≥ 180

-65 -65

23w ≥ 115

/23 /23

w ≥ 5

So, the minimum number of weeks that is required is 5.
