Write in equation passing through the point that is parallel to (8,3); y=-1/4x+7
Answer:
y=-1/4x+5
Step-by-step explanation:
Use the point-slope form which is y-y1=m(x-x1) where m is the slope. In this case, y is equal to 3, and x is equal to 8, and the slope is equal to -1/4. Therefore, the equation will be equal to y-3=-1/4(x-8). Simplify that to get y-3=-1/4x+2. Simplify this again to get y=-1/4x+5. Therefore, the equation is y=-1/4x+5.
Answer:
y = -1/4x + 5
Step-by-step explanation:
Since the lines are parallel, they have the same slope, which is -1/4
Use the point-slope form to do this problem
[tex]y - y_{1} = m(x - x_{1})[/tex] Memorize this form. OK?
y - 3 = -1/4(x - 8)
4y - 12 = -1(x - 8) = -x + 8
4y = -x + 20
y = -1/4x + 5
Eight more than seven times a number is -20
Answer: The number is 0
Step-by-step explanation:
8 = 7x + 8
Then we solve it:
8 = 7x + 8
8 - 8 = 7x
0 = 7x
0 ÷ 7 = x
x = 0

Write an exponential decay function to model the situation in the photo.
Correct answer will get a Brainliest, a 5star rating, and a Thanks !
Step-by-step explanation:
The formula for exponetial equation decay is
[tex]y = a(b) {}^{x} [/tex]
where a is the initial value and b is the decay factor.
A will be 56 since that our initial value.
b will be 0.9 since we are constantly decaying by 0.9.
so our equation is
[tex]y = 56(0.9) {}^{x} [/tex]

1) What is the surface area?
1 ft
8 ft
4 ft
Answer:
88 ft^2
Step-by-step explanation:
For a rectangular prism with dimensions 1 ft by 8 ft by 4 ft, there are two opposite faces with dimensions
1 ft by 8 ft,
two opposite faces with dimensions
1 ft by 4 ft,
and two opposite faces with dimensions
4 ft by 8 ft.
We find their area and add them.
SA = 2 * 1 ft * 8 ft + 2 * 1 ft * 4 ft + 2 * 4 ft * 8 ft
SA = 16 ft^2 + 8 ft^2 + 64 ft^2
SA = 88 ft^2

Step-by-step explanation:
how do you know when the solution of equations is a precise answer and when it is an approximate answer?
Answer:
an answer is precise when it is an exact number like 10, 2, or 123.
An answer is approximate when the decimal numbers are so close that could round it, and the rounded number would be equivalent to the original number. ex: 10.98 = 11

What is the value of x? Pls help
Answer:
x=20
Step-by-step explanation:
ok so that is a pentagon and if you didnt know all of the angles in a pentagon add up to equal 540
so we setup an equation which would be
7x+4x+5+4x+10+5x-5+6x+10=540 and now we just solve for x
step 1 combine like terms
7x+4x=11x
11x+4x=15x
15x+5x=20x
20x+6x=26x
5+10=15
15-5=10
10+10=20
now we have
20+26x=540
step 2 subtract each side by 20
20-20 cancels out
540-20=520
now we have 26x=540
the final step is to divide each side by 26
26/26 cancels out
540/26=20
x=20
hope this helps :D
given X= -7 what is the value of the following expression 4(X-5)+2
Answer: -46
Step-by-step explanation: Place -7 into the equation. 4(-7-5)+2= 4*-7=-28,-4*5=20. Negative 28 minus 20 is -48. Negative 48 + 2 is -46.
HELP ME PLEASE
A certain drug is made from only two ingredients: compound A and compound B. There are 4 milliliters of compound A used for every 7 milliliters of compound B. If a chemist wants to make 1012 milliliters of the drug, how many milliliters of compound A are needed?
These are proportions.
Answer:
368 milliliters.
Step-by-step explanation:
Compound A + Compound B = 1 drug
4 + 7 = 1 drug
11 milliliters = 1 drug, so 1012 milliliters = 92 drugs
Multiply the compounds by the amount of drugs, e.g.
4 x 92 = 368 ( Compound A )
7 x 92 = 644 ( Compound B )
368 + 644 = 1012
368 milliliters of Compound A are needed to make 1012 milliliters of the drug.
Hope this helps :)
LMN ~ TSP Find the value of x.
Answer:
x = 13
Step-by-step explanation:
(x-1)/(x+2) = 8/10

10x-10 = 8x+16
2x = 26
x = 13
Help please I will give you the brainliest
Answer:
x=15 degrees
Step-by-step explanation:
You know that the right angle is split in half to 45 degrees and 3x degrees. Because a right angle is equal to 90 degrees, 3x has to be equal to 45. Therefore, the equation will be 3x=45. You want to make x equal one so you have to divide 3 by each side. The equation will be x=45/3. Simplify that to get x=15. Therefore, x=15 degrees.

help me please this will help my grade !
Answer:
the answers B and D are correct
Answer:
B & D
Step-by-step explanation:
It can-t be A, because that would mean 20², which equals 400, would equal 20.
B is correct because even though it's negative, negative times negative = positive, which would mean that (-sqrt of 20)(-sqrt of 20)=20.
C is wrong because sqrt -20 is an imaginary number,which is a completely different topic.
D is correct because it's the same thing as B, but without the 2 negaties cancelling each other out.
E is the same as A, except it's '-20' x '-20', whcih is still 400, which is still wrong
Hope this helps :)

Determine all the transformations that have happened to f(x) = (x + 4)2 + 2 compared to
f(x) = x2
Answer:
Folow the steps to learn what transformations were determined.
Step-by-step explanation:
First we would have to graph the parent function which is f(x) = x^2. Start by finding your x and y values. Find the y values by plugging in the x values into the parent function.
X Y
2 4
1 1
0 0
-1 1
-2 4
Once these points are plotted you can start determining what are the transformations. Find the difference between the parent function and f(x) = (x + 4)^2 + 2 by looking below.
Vertical Shifts:
f(x) + c moves up,
f(x) - c moves down.
Horizontal Shifts:
f(x + c) moves left,
f(x - c) moves right.
The parent function has to be transformed left 4 and up 2. In order to do this shift each point from earlier left 4 and then up 2. In conclusion you will have two functions graphed (parent function and the transformed function).
Sarah is having people over for her birthday party. If she orders 4 pizzas for 15 people, how many should she order for 30 people?
Answer: 8
Step-by-step explanation:
Answer: 8 pizzas.
Step-by-step explanation:If she is ordering 4 pizzas for 15 people then that simply means that the fraction is 4/15, 15*2 is 30, so that means that our next fraction (Equivalent fraction) will be like this 4/15 = -/30. What ever. Happens to the numerator must happen to the denominator and vice versa. So 4*2 is 8. So the answer is 8.
