Step-by-step explanation:

Find the slope using the formula [ y2-y1/x2-x1 ]

2-2/-5-3

0/-8

0

Find the y-intercept using slope-intercept form [ y = mx + b ] and (3, 2)

y = 0x + b

2 = 0(3) + b

2 = b

Put everything we know into the final form.

y = 0x + 2

y = 2

Best of Luck!

change in y/change in x

y2-y1/x2-x1

2-2/-5-3

0/-8 = 0

The slope is 0 - the answer is d

because when 0x = 0, then you are left with y and only y

when the equation is x=, then the equation is undefined

but, when an equation is y=, that the slope is 0

Chau rented a truck for one day. There was a base fee of $20.99, and there was an additional charge of 79 cents for each mile driven. Chau had to pay $130.80 when he returned the truck.

For how many miles did he drive the truck?

Answers

Answer:

Chau drove 139 miles

Step-by-step explanation:

Knowing how much Chau spent at the end makes the question much much easier. So what you want to do is take of the base fee ($20.99) off the final amount he had to pay.

$130.80 - $20.99 = $109.81

Now you divide $109.81 by the additional charge ($0.79)

Change the divisor (0.79) to a whole number by moving the decimal point 2 places to the right. Then move the decimal point in the dividend (109.81) the same, 2 places to the right.

We then have the equations:

10981 ÷ 79 = 139.000

and therefore:

109.81 ÷ 0.79 = 139.000

Chau drove 139 miles.

shopkeeper sells one machine for 990 re at a profit of 10% and another machine for 1960 at a loss of 2%

Answers

Complete question :

shopkeeper sells one machine for 990 re at a profit of 10% and another machine for 1960 at a loss of 2%. What is his gain or loss percent

Answer:

1.72%

Step-by-step explanation:

Given that :

MACHINE 1:

Sales price = 990

Profit percent = 10%

The cost price of the machine (x) :

10% profit of x :

(100 + 10)% of x = 990

110% of x = 990

1.1x = 990

x = 990/1.1

x = 900

MACHINE 2:

Sales price = 1960

Loss on sale = 2%

Cost price (x) :

(100 - 2)% of x = 1960

98% x = 1960

0.98x = 1960

x = 1960/0.98

x = 2000

Total amount realized from sale = (990 + 1960) = 2950

Total cost of production = (2000 + 900) = 2900

Profit Made = (2950 - 2900) = 50

% profit:

(Profit / cost of production) * 100

(50 / 2900) * 100%

0.0172413 * 100%

profit % = 1.72

The profit made is 50

Cost price of first machine will be:

= 100/(100 + 10) × 990

= 100/110 × 990

= 100 × 9

= 900

Cost price for second machine will be:

= (100 - 2) × x = 1960

= 98% × x = 1960

= 0.98x = 1960

x = 1960/0.98.

x = 2000

The total cost price = 900 + 2000 = 2900

Total selling price = 990 + 1960 = 2950

Therefore, profit will be:

= Selling price - Cost price .

= 2950 - 2900

= 50

Answers

Answer:

A

Step-by-step explanation:

It’s the answer I did the math

The unit rate for the ratio is 3 laps per miles.

Given that the ratio is 78 laps/26 miles.

What is the ratio?

The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.

Now,

Unit rate =78 laps/26 miles

Divide both the numerator and the denominator by 26.

So, 78 laps÷26 miles/26 miles÷26 miles

= 3 laps/miles

Therefore, the unit rate for the ratio is 3 laps per miles.
