Answer: 1) y = 4x + 5

2) y = 3x + 2

3) y = (-5/6)x + 1/3

Step-by-step explanation:

Use the Point-Slope equation: y - y₁ = m(x - x₁) where

(x₁, y₁) is a point on the line
m is the slope

(x₁, y₁) = (-1, 1) m = 4

y - 1 = 4(x + 1)

y - 1 = 4x + 4

y = 4x + 5

(x₁, y₁) = (1, 5) m = 3

y - 5 = 3(x - 1)

y - 5 = 3x - 3

y = 3x + 2

(x₁, y₁) = (-2, 2) m = -5/6

y - 2 = -5/6(x + 2)

y - 2 = (-5/6)x - 5/3

y = (-5/6)x + 1/3

Answer:

∛4²

Step-by-step explanation:

A fraction exponent can be represented using a radical. The base number is the number in the radical. The numerator of the fraction is the exponent inside the radical. The denominator is the type of radical.

To write an exponent in radical form , the denominator, or index goes in front of the radical, and the numerator goes inside of the radical. We raise the base to the power of the numerator

Man borrows 26,000 for 3 years with simple interest 1.7 percent determine the amount of money repay after three years

Naya [18.7K]

Answer:

$1,326

Step-by-step explanation:

You are going to want to use the simple interest formula for this.

$I=Prt$

I = interest amount

P = principal amount

r = interest rate

t = time

First, change 1.7% into its decimal form:

1.7% -> $\frac{1.7}{100}$ -> 0.017

Next plug in the values into the equation:

$I=26,000(0.017)(3)$

$I=1,326$

After three years, he must repay $1,326.

A chocolate company produces 2 types of chocolate: type a and type b. The company selects 25 random packages of each type to che

Taya2010 [7]

Answer:

80 chocolates type 'a' and 240 chocolates type 'b'

Step-by-step explanation:

The company selects 25 random packages of each type from which one of type a has an incorrect weight and three of type b have an incorrect weight.

We can say that $\frac{1}{25}=0.04$ = 4% of the chocolates type 'a' have an incorrect weight while $\frac{3}{25}=0.12$ = 12% of chocolates type 'b' have an incorrect weight.

Now, if the company selects 2000 random chocolates of each type we ca predict that the amount of chocolates that have an incorrect wright will be:

Type 'a': 2000x0.04 = 80

Type 'b': 2000x0.12 = 240

So the company is expected to find 80 chocolates type 'a' and 240 chocolates type 'b' that have incorrect weight.
