What is the equation of the line perpendicular to 2x – 3y = 13 that passes through the point (-6, 5)?
O Y=2/3x+9
O y=-3/2x-4
O y=-3/2x-13
O y=2/3x-1
Answer:
Option 2, y=-3/2x-4
Step-by-step explanation:
Solve with the point-slope formula: y-y1=m(x-x1). The line is perpendicular, meaning the slope of the new equation will be the oppposite reciprocal of the original slope.
First, we need to rewrite the original equation into standard form.
2x-3y=13
-3y=13-2x
y=-13/3+2/3x
From this, we can see that the slope here is 2/3. Since the line we're looking for is perpendicular, the opposite reciprocal of that slope is -3/2.
Now, we can plug in the coordinates we have into the formula (-6, 5), along with our slope (-3/2).
y-(5)=-3/2(x+6)
y-5=-3/2x-9
y=-3/2x-4
And to check, we can just plug the coordinates into our new equation:
Check:
(5)=-3/2(-6)-4
5=9-4
5=5

Step-by-step explanation:
UPS charges $7 for the first pound, and $0.20 for each additional pound. FedEx charges $5 for the first pound and $0.30 for each additional pound.
How many pounds, p, will it take for UPS and FedEx to cost the same? What is the cost? Write and solve an equation to show your work.
Answer:
1. 20 pounds
2. $11
Step-by-step explanation:
To set this up, you have to use a system of equations. It would look like this, where [tex]p[/tex] is pounds and [tex]t[/tex] is total cost:
UPS: [tex]t=7+0.20p[/tex]
FedEx: [tex]t=5+0.30p[/tex]
In order to solve a system of equations you must either a.) graph it, or b.) set them equal to each other.
If you graph it, the answer is where the two lines intersect.
If you set them equal to each other, solve it.
I will set them equal to each other in this:
[tex]7+0.20p=5+0.30p[/tex]
The first step in a problem like this, where there's the same variable on both sides, is to subtract the smaller variable from both sides. In this case, it is [tex]0.20x[/tex]. That would turn the equation into:
[tex]7=5+0.10p[/tex]
After that, you must solve it like a regular two-step equation.
Start by subtracting 5 from both sides:
[tex]2=0.10p[/tex]
Now, you must divide both sides by [tex]0.10[/tex].
[tex]\frac{2}{0.10}=\frac{0.10p}{0.10}[/tex]
That would give us:
[tex]20=p[/tex]
This means that in order for the prices to be the same, the package must be 20 pounds.
Now in order to find the total cost, you must plug 20 into one of the equations. It doesn't matter which, since they both equal the same. I will plug it into the FedEx equation:
[tex]t=5+0.30(20)[/tex]
Now you can just use a calculator and solve that or do it by hand. Multiply 0.30 by 20, to get 6, then add 5, which equals 11.
You should get: [tex]t=11[/tex].
This means that the total cost, when the costs are the same for both FedEx and UPS, is $11.

Combine Like Terms
Addition Property of Equality
Distributive Property
Given
Multiplication Property of Equality
Answer:
x = -10/3
Step-by-step explanation:
−4(x−5)=−7x+10
Use the distributive property to multiply −4 by x−5.
−4x+20=−7x+10
Add 7x to both sides.
−4x+20+7x=10
Combine −4x and 7x to get 3x.
3x+20=10
Subtract 20 from 10 to get −10.
3x=−10
Divide both sides by 3.
x = -10/3

HELPPP PLEASE I NEED THIS BY FRIDAYYYYY!!!!
Answer:
<ABD = 44
<DBC = 44
<ABC = 88
Step-by-step explanation:
If an angle bisects another, then the two resulting angles are equal
In this case <ABC is bisected by BD
which means that
<ABD = <DBC
so
6x + 14 = 3x + 29
simplify and solve using inverse operations
6x + 14 = 3x + 29
-3x -14 -3x -14
3x = 15
/3 /3
x = 5
now substitute into the given values
< ABD = 6x + 14
= 5 * 6 + 14
= 30 + 14
= 44
<DBC = 3x + 29
= 5 * 3 + 29
= 15 + 29
= 44
< ABC = <ABD + <DBC
<ABC = 44 + 44
= 88

who wants a brainist whats the how do you convert ratios
Answer:
To a whole number: Add the numbers in the ratio togetherTo a fraction: Each number in the ratio would become a numerator in a fractionI hope this helps!
Credit goes to: calculatorsoup.com
Answer:
To convert, start by adding both parts of the ratio together. This will be the denominator for each of the fractions and also represents the whole set. Then, each part of the ratio creates a fraction, with the numerator being the first part of the ratio and the denominator being the sum that was just found.
