Use tens to solve 13-7

1 answer:

4 0

You can change it to 130-70 and that'll give you 50.

Then just cross out the 0 from the 50 since 13-7 didn't have any zeros. So 5.

Find the slope of the line that passes through Point A $$(−1,0) and Point B $$(0,2) using $$m=

vitfil [10]

Slope (m) equals rise over run
Y-intercept is when x=0
Up (rise) two over (run) one, so 2/1=2 would be your slope.
When x=0, y=2. 2 is your y-intercept.
Plug those into the equation y=mx+b
Y=2x+2. Which is your answer. Glad to help

M is directly proportional to r cubed when r = 4, m = 160. Find the value of r when m = 540

Anarel [89]

Answer:

r = 6

Step-by-step explanation:

Given that M is directly proportional to r³ then the equation relating them is

M = kr³ ← k is the constant of proportionality

To find k use the condition r = 4 when M = 160

k = $\frac{M}{r^3}$ = $\frac{160}{64}$ = 2.5, so

M = 2.5r³ ← equation of proportionality

When M = 540, then

540 = 2.5 r³ ( divide both sides by 2.5 )

216 = r³ ( take the cube root of both sides )

r = $\sqrt[3]{216}$ = 6

A consumer has $100 per day to spend on product A, which has a unit price of $7, and product B, which has a unit price of $15. W

kifflom [539]

Answer:

-15/7

Step-by-step explanation:

Let B(x1, y1) be on vertical (y-axis) then B = (0, 15) and

A(x2, y2) be on horizontal (x-axis) then A = (7, 0).

Now, slope = (y2 - y1)/(x2 - x1)

then slope = (0 - 15)/(7 - 0)

=> slope = (-15)/7

slope of the budget = -15/7
