Answer:
y= -3/4x - 4Step-by-step explanation:
To write an equation that is perpendicular to a given line, take the negative reciprocal of the given slope. the given slope is 4/3, so the negative reciprocal is -3/4.
Using slope-intercept form of a linear equation, y=mx+b substitute in -3/4 for "m" the slope.
y=-3/4x+b
Now you need to "b" the y-intercept using the given point (-4,-1). Substitute the values in the equation. -1=-3/4(-4)+b simplify
-1= 3 + b subtract 3 for both sides
-4=b
substitue -4 for b. Now you have y= -3/4x - 4 this is your answer.

Solve for the variable x.
4(x - 11) = -210
Answer: Divide both sides by the numeric factor on the left side, then solve.
Exact Form: x= −83/2
Answer: x = -41.5
Step-by-step explanation:
Distribute the 4 that is outside of the parentheses.
4 times x = 4x
4 times -11 = -44
Then to isolate the variable add 44 to both sides of the equation to cancel out -44.
-44 + 44 = 0
-210 + 44 = -166
Now your equation should 4x = -166
To find x, divide both sides of the equation by 4.
4x divded by 4 is x.
-166 divded by 4 is -41.5.
So the answer is x = -41.5.
To check the answer, plug in -41.5 to the x.
4(-41.5 - 11) = -210
Use the recursive formula f(n) = 0.4 ⋅ f(n − 1) + 11 to determine the 2nd term if f(1) = 4.
Answer:
12.6Step-by-step explanation:
Given the recursive formula
f(n) = 0.4 × f(n − 1) + 11 and first term is f(1) = 4Finding the 2nd term:
f(2) = 0.4×f(1) + 11f(2) = 0.4×4 + 11 = 1.6 + 11 = 12.6Answer:
12.6
Step-by-step explanation:
Given the recursive formula
f(n) = 0.4 × f(n − 1) + 11
and first term is f(1) = 4
Finding the 2nd term:
f(2) = 0.4×f(1) + 11
f(2) = 0.4×4 + 11 = 1.6 + 11 = 12.6

Tony wants to make a dog bed for his dog. He has a Golden Retriever and wants to make sure the bed is big enough so his dog can stretch out. He buys 8 yards of fabric for the bed. The fabric he chooses costs $6.99 per yard. He also needs to buy a filling for the bed. He buys 3 bags of polyester filling, which are $7.99 a bag. How much will Tony pay for the materials for the dog bed?
A. $23.97
B. $55.92
C.$38.87
D.$79.89
Answer:
D.$79.89
Step-by-step explanation:
Cost of one yard of fabric = $6.99
Length of fabric bought = 8 yards
Cost of one bag of polyester filling = $7.99
Number of bags of polyester filling bought = 3
Total cost of fabric = [tex]6.99\times 8=\$55.92[/tex]
Total cost of polyester filling = [tex]7.99\times 3=\$23.97[/tex]
Total cost of materials bought = Total cost of fabric + Total cost of polyester filling
[tex]=55.92+23.97=\$79.89[/tex]
Total cost of materials bought is [tex]\$79.89[/tex].
The measurement of the “ridge” of your new house on blueprints is 24 inches. If the scale is 1/4 = 1ft how long is the wall in real life
Answer:
In real the wall will be: 96 ft
Step-by-step explanation:
Given that the scale is
1/4 = 1ftIt means 1 inch will represent 4 ft.
so
1 inch = 4ft
Given that the measurement of the “ridge” of your new house on blueprints is 24 inches.
Thus,
24 inches = 24 × 4ft ∵ 1 inch = 4ft
= 96 ft
Therefore, in real the wall will be: 96 ft

Can anyone show me how to solve this problem? I know that its 5 weeks. (The problem is “Ahmed is saving his money to buy a Ipad that costs $319.50. Right now he has $21.95, and can save $63.00 each week. How many weeks will it take for Ahmed to have enough money to buy the Ipad)
Answer:
5 weeks
Step-by-step explanation:
Substract 319.5 (the amount he has to save) to the amount he has already saved, which is 21.95. Now the constant amount of change is 63 dollars each week so divided it by that. So the equation should be (319.5-21.95) and divide all that by 63 to get 4.72 or rounded to the nearest number, is 5.
Express z 1 = 17 [ cos ( π ) + i sin ( π ) ] z 1 =17[cos(π)+isin(π)]z, start subscript, 1, end subscript, equals, 17, open bracket, cosine, left parenthesis, pi, right parenthesis, plus, i, sine, left parenthesis, pi, right parenthesis, close bracket in rectangular form. Express your answer in exact terms.
Answer:
z1 = -17 + 0i
Step-by-step explanation:
Given the complex number z1 =17[cos(π)+isin(π)], we are to express it in rectangular form as shown;
Since cos(π) = -1 and sin(π) = 0, the equation becomes;
z1 =17[cos(π)+isin(π)]
z1 =17[(-1)+i(0)]
z1 = 17(-1 + 0i)
z1 = -17 + 0i
Hence the complex number in rectangular form is expressed as z1 = -17 + 0i

Klara picks a number. She rounds to the nearest hundred. She rounds tot the nearest thousand. She rounds the number to the nearest ten thousand. All three times, the result is the same. Which choice could be klara's number?
Answer with step-by-step explanation:
The question does not seem complete, but I'll try to make some explanations.
When you want to round a number, there are some rules.
1. If the number you are rounding is followed by 5, 6, 7, 8, 9, then round the number up, that is add 1 to it.
2. If the number you are rounding is followed by 0, 1, 2, 3, 4, then round the number down, that is add 0.
Now if given a number and you are asked to round to the nearest 100, 1 000, 10 000 and so on, then for nearest 100, count 2 numbers from the back. Whatever number you stop at, that is the number you are to round. For 1000 count 3, for 10 000 count 4 and so on.
Since Kiara is having the same value after rounding, it means she picked a number that has zeros after the 10 000th value
Let's assume she picked: 70 000
Rounding that number to nearest 100, 1000 and 10000 gives the same number which is
70 000.
Nicole is running for school president. Her best friend designed a campaign poster, which measured 3 feet by 2 feet. Nicole like the poster so much, she reproduced the artwork on rectangular buttons that measured 2 inches by 1 1/3. What is the scale factor?
Answer:
The scale factor is 18 to 1 for the painting
Step-by-step explanation:
Here we want to get the scale factor of the original to what is reproduced
Let us have same units first
Mathematically;
1 foot = 12 inches
3 feet = 36 inches
2 feet = 24 inches
So 36 to 2 and 24 to 1 1/3
That will be ratio 36/2 = 18 to 1
same as 25 divided by 1 1/3 = 18 to 1
