A line with a slope of 10 passes through the point (0, 10). What is its equation in
slope-intercept form?

Answers

Answer:

y = 10x + 10

Step-by-step explanation:

(0,10) means that the y is 10 when the x is 0, which is the y-intercept

y-intercept: 10

b = y-intercept

m = slope

slope: 10

y = mx + b

y = 10x + 10

Answer:

The answer to the question provided is 16 units.

Step-by-step explanation:

☆Well, we simply use the distance formula, which is:

[tex]d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} }[/tex]

...

☆All we need to do is plug in!

[tex]d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} } \\ \\ d = \sqrt{(9 - 25) {}^{2} + (12 - 12)^{2} } \\ d = \sqrt{( - 16)^{2} + (0) ^{2} } \\ d = \sqrt{256 + 0} \\ d = \sqrt{ 256 } \\ d = 16[/tex]

at a sale, dresses sold for 22.00 each. This price was 55% of a dress's original price.

Answers

Answer:

22.00x55%=12.10. 22-12.10=9.90

Answer:

$40

Step-by-step explanation:

22/55 = dollar per percent

dollar per percent = 0.4

0.4 x 100 will equal to 100% of the original price

0.4 x 100 = 40

to check, 40 x 55% = 22

A fraternity charged $2.00 admission for dudes and $1.00 for ladies for their finals week bash. The fraternity made $100.00 and sold 70 tickets. How many ladies attended the party?

Answers

Given : 2D + 1L = 100,
And D + L = 70

This is a simultaneous equation can be solved as follows

2D + L = 100
- D - L = -70
————————————-
D - 0 = 30

i.e D (number of dudes) = 30

Therefore, since we already know the fraternity sold 70 tickets in total,

70 -30 = 40 (the number of ladies attended)

Damon's father pays him one dollar to start the work and

doubles his pay for each hour of work. Write a function that

models this situation.

Answers

Answer: p(x) = $1*(2)^x

Step-by-step explanation:

First, the father pays him $1 for only starting the work, and for each hour, the payment is doubled.

So after the first hour, the payment wil be 2*$1 = $2.

After the second hour, the payment will be 2*(2*$1) = $1*(2)^2

After another hour, the payment will be 2*($1*(2)^2) = $1*(2)^3

We already can see the pattern here, after x hours, the payment will be:

p(x) = $1*(2)^x

This is the function that models this situation.

Coffee costs $3.59 per pound. How much would 5.7 pounds of coffee
cost?

Answers

Answer:

20.463

Step-by-step explanation:

3.59x5.7

5.7 pounds of coffee would cost $20.463.

What is simplification?

When a mathematical expression is converted into an equivalent, typically shorter statement, it becomes simpler. Procedure simplification is one method to encourage uniformity in work effort, expense, and duration. It reduces diversity and variation that is detrimental, pointless, or unnecessary.

Given, Coffee costs $3.59 per pound. Since,

1 pound of coffee costs = 3.59$

5.7 pounds of coffee costs = 3.59 * 5.7

5.7 pounds of coffee costs = 20.463

Therefore, $20.463 would be the cost of 5.7 pounds of coffee.

That was because enough enslaved children were born, lived, and grew to become adults. There was just one exception to this rule: Louisiana, where the native-born enslaved population kept dropping. Sugar was a killer.Unlike the Caribbean, Louisiana has cold snaps. That put an additional pressure on the sugar harvest. Not only did the slaves need to harvest the cane in perfect rhythm with the grinding mills, but the entire crop had to be cut down between mid-October and December.
