Slope is -2/5 and y-intercept is 2

Step-by-step explanation:

  • Step 1: Write the equation in slope-intercept form y = mx + b

2x + 5y = 10

5y = -2x + 10

y = -2/5 x + 10/5

y = -2/5 x + 2

  • Step 2: Find the slope and y-intercept from the equation.

Slope, m = -2/5

y-intercept, b = 2

Phoebe usually drives to work each day on a 12-mile road that is currently closed for construction. While the road is closed she
Mumz [18]

The total distance phoebe has to drive each day (round trip) while her usual route is closed is 42 miles

<h3>What is a Pythagoras theorem?</h3>

The square of the longest side is equal to the square of the sum of the othersides.

Before we can calculate the total distance, we will need to get the hypotenuse on  both sides using the Pythagoras theorem as shown:

H^2= 12^2 + 9^2

H² = 144 + 81

H² = 225

H = 15

For the other hypotenuse

h² = 12² + 5²

h² = 144 + 25

h²  = 169

h = 13 mils

The total distance = 5 + 15 + 9 + 13

The total distance = 42 miles

The total distance phoebe has to drive each day (round trip) while her usual route is closed is 42 miles

100 pts Eight stuffed animals need to be arranged in a line. There is one bear and one zebra. What is the exact probability that
shtirl [24]

Answer:

1/56

Step-by-step explanation:

P( bear  is first) = bear/ total = 1/8

Then there are 7 animals left

P( zebra is 2nd) = zebra /total = 1/7

P( bear, then zebra) = 1/8 * 1/7 = 1/56

6) Alberto invests $8,534 in a retirement
ludmilkaskok [199]

Answer:

  17 years

Step-by-step explanation:

The compound interest formula is ...

  A = P(1 +r/n)^(nt)

where P is the principal invested at annual rate r, compounded n times per year for t years.

Filling in the numbers and solving for t, we find ...

  16826.03 = 8534(1 +.04/12)^(12t)

  16826.03/8534 = 1.0033333...^(12t)

Taking logs, we have ...

  log(16826.03/8534) = 12t·log(1.0333333...)

Dividing by the coefficient of t gives ...

  log(16826.03/8534)/(12·log(301/300)) = t ≈ 17.000

It will take 17 years for the account balance to reach $16,826.03.

Help me please I really need help with this please someone
kolezko [41]

Step-by-step explanation:

For number 5 the answer would be <em>economy</em> because there is a <u>2 dollar difference</u> and the shampoo bottle has 20 more ounces then the <em>regular</em> bottle. The <u>2 dollar difference</u> changes the whole thing.

For number 6 the answer is still <em>economy</em> because you get more ounces in the bottle of shampoo for a <u>3 dollar difference</u> in the price.

:)

BTW HOPE YOU HAVE AN AMAZING DAY!!!
