What is the equation of the line in point slope form given a slope of -3 and a point of (-2,-5)?
Answer:
y = -3x - 11
Step-by-step explanation:
Use the given slope and point in the point-slope equation. Solving this will give us the y-intercept equation.
Point-slope formula: y - y = m(x - x)
Plug in the slope and point
y - (-5) = -3(x - (-2))
Subtracting negatives will make them positive. Multiply out the -3 to what is in the parentheses.
y + 5 = -3x - 6
Subtract the 5 from both sides
y = -3x - 11
The equation of the line is y = -3x - 11

-2 -(-4) -2= ?
thx for the answer plz explain when u answer
Answer:
0
Step-by-step explanation:
-2-(-4)-2
We can break down the problem first. The beginning of the problem is...
-2-(-4)
Two negatives make a positive. An equivalent way to say this is
-2+4
-2+4=2
Next, we can solve for the last part. At the end of the equation, you have to subtract 2, so that's what we'll do!
2-2=0
The answer to this is 0!
I hope you understood the explanation...have an amazing day!!!! :3

The circumference (C) of a circle is calculated as
C = πd ( d is the diameter )
(4)
Here d = 18, thus
C = 18π in
(5)
Here C = 50π, thus
πd = 50π ( divide both sides by π )
d = 50 in
The radius r is one half of the diameter , thus
r = 50 ÷ 2 = 25 in
Find the product of D = BA.
d11 = 0
d12 = 6
d21 = 1

George is making brown paint he wants to make brown paint he must mix purple and yellow paint together in a 1:1 ratio. In order to make purple he must mix red and blue paint together at a ratio of 2 quarts red to 1 quart of blue. How many quarts of yellow does he need
Answer:
3/4 quarts of yellow paint is needed
Step-by-step explanation:
From the question, we are told that:
In order to make purple he must mix red and blue paint together at a ratio of 2 quarts red to 1 quart of blue.
3 quart of Purple paint mix requires 2quarts of red paint and 1 quart of blue paint.
We are also told that:
When George wants to make brown paint he must mix purple and yellow paint together in a 1:1 ratio.
This means 1 Purple paint to 1 Yellow paint
4/4 quarts of Yellow paint = 1 yellow paint
3/4 quarts of Yellow paint = 3/4 quarts of purple paint

Raia purchases a new car for $32,000 and finances it with a 6-year simple interest loan at a rate of 4.25% What are Raia’s monthly car payments?
Answer:
569
Step-by-step explanation:
Raia’s monthly car payments is $8160.
What is simple interest?Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest.
Given that, Raia purchases a new car for $32,000 and finances it with a 6-year simple interest loan at a rate of 4.25%
We need to find;
What are Raia’s monthly car payments?
So, SI = PRT / 100
P = Principal amount
r = rate
T = time
So,
SI = 32000 x 4.25 x 6 / 100
= 8160
Hence, Raia’s monthly car payments is $8160.

Oil is spilled onto a kitchen floor. The area covered by the oil at time t is given by the function A, where A(t) is measured in square centimeters and t
is measured in seconds. Which of the following gives the rate at which the area covered by the oil is changing at time t=10?
Answer:
did you ever fine out the answer to this lol
Step-by-step explanation:
Oil is spilled onto a kitchen floor. The area covered by the oil at time t is given by the function A, where A(t) is measured in square centimeters and t
is measured in seconds. The rate at which the area covered by the oil is changing at time t = 10 is A'(10).
Given that:
The area covered by the oil at time t = A(t)To determine the rate at which the area covered by the oil is changing with time, we need to differentiate A(t) with respect to time t.
∴
By differentiation:
[tex]\mathbf{\dfrac{dA}{dt} =A'(t)}[/tex]
The rate at which the area covered with oil is changing is t = 10∴
[tex]\mathbf{\dfrac{dA}{dt} \Big| _{t=10}=A'(t)\Big|_{t=10}}[/tex]
[tex]\mathbf{\dfrac{dA}{dt} =A'(10)}[/tex]
Therefore, we can conclude that the rate at which the area covered by the oil is changing at time t=10 is A'(10).

Answer:
11 1/5 feet!
Step-by-step explanation:
He needs a total of 27 9/10 feet! 11 1/2 + 5 1/5 is 16 7/10 feet! If we need 27 9/10 feet, we subtract 16 7/10 ft from 27 9/10 ft to get 11 2/10, which we can reduce 2/10 to be 1/5.
So, he needs 11 1/5 feet of wood more to build the doghouse for his new puppy!

Evaluate x3−y2 if x=2 and y=34
Answer:
- 62Step-by-step explanation:
Evaluate x3−y2 if x=2 and y=34
substitute x=2 and y=32 into the expression:
= x3 - y2
= (2)3 - (34)2
= 6 - 68
= -62
An expression is defined as a set of numbers, variables, and mathematical operations. The value of the expression x³−y², when x=2, y=34 is −1,148.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Given the expression x³−y² and the value of the expression when x=2 and y=34 can be calculated by substituting the values in the expression. Therefore, the expression can be written as,
x³ − y²
Substitute the value of x and y in the expression,
= (2)³ − (34)²
Opening the bracket,
= 8 − 1,156
= −1,148
Hence, the value of the expression x³−y², when x=2, y=34 is −1,148.

Below is a scale drawing of a stage that Syla is designing. A rectangle with length 8 centimeters and width 5 centimeters. Using the scale 1 cm : 7 m, Syla calculated the width, or the shorter side of the stage, to be 35 m. She decides to change the scale to 1 cm : 10 m. What is the width of the new stage?
Answer:
50mStep-by-step explanation:
Given the dimension
Length of the rectangle = 8cm
Width = 5cm
Note that when the scale was 1:7, syla multiplied the width by a factor of 7 i.e 5*7 = 35m
If syla changes the the scale to 1 cm : 10 m for the rectangle, then the width of the shorter side will be multiplied by a factor of 10 due to the change in scale i.e;
5 * 10 = 50m
Hence the width of the new stage will be 50 m
Answer:
50m

Hank invested $50,000 in a mutual fund that earns 7% interest compounded annually. How much interest did he earn after 10 years?
F)$35,000
G)$48,357.57
H)85,000
J)98,357.57
Answer:
F $35,000
Step-by-step explanation:
3,500 is 7% of 50,000 3500 multiplied by 10 years= 35,000
9514 1404 393
Answer:
G) $48,357.57
Step-by-step explanation:
The future value formula can be used to find the account value:
FV = P(1 +r)^t
where P is invested at annual rate r for t years.
FV = $50,000(1.07^10) ≈ $98,357.57
The amount of interest earned is the difference between this value and the value of the initial investment:
interest = $98,357.57 -50,000 = $48,357.57
Hank earned $48,357.57 in interest after 10 years.
_____
At 7% interest, the "rule of 72" tells you the doubling time of the account is about 72/7 = 10.3 years. That is the account value will be not quite double the original investment after 10 years. So, the amount of interest earned is only slightly less than $50,000. If the account earned simple interest, the interest earned would be $35,000. Only one answer choice is more than $35,000 and less than $50,000.
