you know that your line is perpendicular to the line with equation y equals 3x + 5 right whenever a line is perpendicular to another perpendicular not parallel to the line has a negative slope of the other line for example if you had a line with slope 2 x in the line perpendicular to that would have slope -1 / 2X so then you line in your question has slope -1 / 3 x by doing the Rococo of 3 and adding a negative sign to your equation sulfur looks like this y equals negative 1 / 3 x + B where is B is a constant 3 all you have to do is solve for b is a plug in the coordinate values 6 equals x minus -2 equals one in rearrange y equals -1 / 3 x + B negative two equals negative one over three 6 plus b negative two equals negative two plus be there for me easy roast F4U equation of the line is y equals -1 / 3 x
Explain how to find the surface area of a rectangular prism.
Answer:
To find the surface area of a rectangular prism you must multiple the length and the width. You can choose the top and do 2(L*W) and one of the square sides 2(L*W) and the front 2(L*W) and add it all up.
2(L*W)+2(L*W)+2(L*W)= surface area
There is a 2 because there are two side of a rectangular that are the same. Since there are 6 sides on a rectangle. Only 3 pairs are similar.

Find each of the following angles and arcs formed in circle R. (PLEASE HELP!! WILL MARK BRAINLIEST!)
Answer:
m<RTV = 90°
m<TRU = 129°
m<TVU = 51°
m<TSU = 64.5°
mST = 101°
mSTU = 230°
Step-by-step explanation:
i just did it:)
The measure of each angles are; m<RTV = 90°, m<TRU = 129°, m<TVU = 51°, m<TSU = 64.5°, mST = 101° and mSTU = 230°.
What is a circle?A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.
Since Angle RTV is formed by the segments RT - that is the radius of the circle, and TV, which is tangent to the circle at point T. The radius always forms a right angle with the tangent lines.
Hence, the measure of angle RTV is; 90°.
The measure of a central angle and the measure of the intercepted arc would be equal. Hence, the measure of angle TRU is 129°.
Since RTVU is a quadrilateral. We know that 3 of the interior angles' measures are 90°, 90°, and 129°. The measures of the interior angles of any quadrilateral add up to 360°, the measure of angle TVU is 51°.
Thus the measure of angle TSU is 64.5°.
Also the sum of all consecutive arcs in a circle is 360°,
We know that mTU = 129° and mUS = 130° then the measure of arc ST is 101°.

Find the GCF for the list.
−15x^3 , 6x^4
Answer:
the GCF is 3x^3
Step-by-step explanation:
Identifying the greatest common factor of an expression like this one involves finding the GCF of each term when the terms are placed side by side: the GCF of -15x^3 and 6x^4 is 3x^3, because 3 and x^3 are the largest factors of their type (constant, power of x) that will divide evenly into -15x^3 and 6x^4.
The end result is 3x^3(-5, 2x). Once again, the GCF is 3x^3.

Dexter ran 5 miles as part of his training. How many yards did he run?
Answer:
8800 yards
Step-by-step explanation:
The total number of yards ran by Dexter for his training is given by the equation A = 8800 yards
What is unit conversion?In order to translate measurements of a particular amount between different units, a mathematical conversion factor is usually used. This modifies the measurement of the quantity without altering its effects.
The particular circumstances or the intended result control the conversion process. This may be governed by law, a contract, a list of technical specifications, or other publicly available standards.
A precise conversion from one system to another is necessary for some measures in order to maintain the precision of both the original measurement and the conversion.
Based on the connection between a particular pair of original units and a particular pair of target units, each conversion factor is chosen.
Given data ,
Let the total number of yards ran by Dexter be A
Now , the total number of miles ran by Dexter = 5 miles
where from the unit conversion ,
1 mile = 1760 yards
So , the total number of yards ran by Dexter for his training A = 5 x 1760
The total number of yards ran by Dexter for his training A = 8800 yards
Hence , the number of yards is 8800 yards

Answer:
(3,0) (0,9)
Step-by-step explanation:
To find the x-intercept, y must equal 0
9x+3(0)=27 substitute
9x=27 divide
x=3 (3,0)
To find the y-intercept, x must equal 0
9(0)+3y=27 substitute

A mixture contains 3.7 × 10–6 grams of carbon powder and 0.000092 grams of ammonium carbonate.
What is the difference in the amounts of carbon powder and ammonium carbonate?
Answer:
The difference in the amounts of carbon powder and ammonium carbonate is [tex]88.3\times 10^{-6}[/tex] grams.
Step-by-step explanation:
According to this statement, we have a mixture with [tex]3.7\times 10^{-6}[/tex] grams of carbon powder and [tex]92\times 10^{-6}[/tex] grams of ammonium carbonate. The difference between those amounts consist in subtracting the latter quantity for the former one. That is:

[tex]\Delta m = 88.3\times 10^{-6}\,g[/tex]
The difference in the amounts of carbon powder and ammonium carbonate is [tex]88.3\times 10^{-6}[/tex] grams.

What is the volume of a hemisphere with a diameter of 8.6 ft, rounded to the nearest tenth of a cubic foot?
Answer:
166.52 cubic feet.
Step-by-step explanation:
We can Know the volume of a by using the expression below
V =[ (4/3)πr^3] .............eqn(1)
Given Diameter= 8.6 ft
radius= Diameter/ 2 = (8.6 ft)/2 = 4.3 ft
Eqn(1) gives the formula for volume of a WHOLE sphere, but what we need is
HALF of whole sphere, then we have
V =[ (4/3)πr^3] / 2
Then eqn(1) becomes [ (2/3)πr^3]
Volume of hemisphere
= [ (2/3)πr^3].....eqn(2)
If we substitute into eqn(2) we have
Radius= 4.3 ft
V(hemisphere) = (2/3)π(4.3)^3
= 166.52 cubic feet.
Hence, the volume of a hemisphere is
166.52 cubic feet.
Given the area of a trapezoid is 86 in’, and the height is 4 in. If one base is 18 in, determine the other base.
Answer:
25 = base
Step-by-step explanation:
I searched all of this on YT to try and help
so first we need to know the area of a Trapezoid
A = 1/2h(b + b)
86 = 1/2(18 + b)4
we dont know the base where going to put b
we also dont like fractions so where going to get rid of 2 by multiplying 2 by 2. And we do it in both ends, so where doing the same with our Area.
172 = (18 + b)4
the 4 is multipling so divide it on both ends.
43 = (18 + b)
then do the opposite operation on the 18, by subtracting 18 on both sides.
25 = b
is the base
check the work by plugging it back in
A = 1/2h(b + b)
A = 1/2 4(18+25)
A = 1/2 4(43)
A = 1/2(172)
A = 86in

Step-by-step explanation:
We know that 4 1/2 is 4.5.
Take 4.5 to the other side.
h=2.5
By the way, can you follow me on Brainly?
Thanks!
Answer:
5/2, or 2 1/2
Step-by-step explanation:
To find the value of h you want to get h by itself, so you must subtract 4 1/2 from both sides of the equation. 4 1/2 can be rewritten as 9/2, but you must find a common denominator between 7 and 9/2. A common denominator can be 2, if 7 is changed into 14/2. The equation is now 14/2 - 9/2, which gives you 5/2 or 2 1/2.
