What is an equation for the linear function whose graph contains the points (2, 5) and (3, 0) ?

Answers

y = -5x + 15

You can use point slope formula to get the answer

Answer: x + 5y - 15 = 0

Step-by-step explanation:

First, we find the slope

Given : x₁ = 2 y₁= 5 x₂= 3 y₂=0

m = y₂ - y₁ / x₂ - x₁

m = 0-5 / 3-2

m = -5 / 1 = -5

equation of a straight line;

y - y₁ = m (x - x₁)

y - 5 = -5(x - 2)

y - 5 = -5x + 10

y + 5x - 15 = 0

1. simplify 6^2+ 3^2
2. 4^3+ 4.5

Answers

1. 45
2. 68.5

please mark me brainliest!!!

1. Use the correct order of operations and do the exponents first.
Remember that an exponent of 2 means to multiply the base by itself, not multiply the base by 2.

6^2+ 3^2 = 6 * 6 + 3 * 3 = 36 + 9 = 45

2. 4^3 + 4.5 = 4 * 4 * 4 + 4.5 = 64 + 4.5 = 68.5

Answers

Well let's see first 61.84-11 as it is a constant which you then get 50.84. Now take the 50.84 and divide it by .04 per minute. which you should get 1271 minutes.

(55 km/h) * (1 mi)/(1.609344 km) ≈ 34.2 mi/h

_____
You can do units conversions pretty easily by multiplying by a conversion factor whose value is 1. That is, since
.. 1 mi = 1.609344 km
dividing by the left side we have
.. (1 mi)/(1.609344 km) = 1
This factor has the convenience that it will cancel km and give mi when multiplied by some number off km. That is what we did above. (The "per hour" just went along for the ride. It did not get involved in the units conversion.)

find the coordinates of the orthocenter for a triangle with vertices (1,3) , (1,12) , (8,10)

Answers

the orthocenter is (3,10) I think

For convenience, I'll name the three points: A(1, 3), B(1,12), C(8,10)

The orthocenter is where the three altitudes of the triangle meet. That is, where the perpendicular lines from each vertex to the opposite side meet.

the goal in this case is to find out where the perpendicular line from C to AB, the perpendicular line from B to AC, and the perpendicular line form A to BC meet.
It is enough to find two perpendicular lines.

step one: find the equation of two perpendicular lines

find the slope of AB: m=(12-3)/(1-1), notice the denominator is 0, so the slope doesn't exist, that means AB is a vertical line parallel to the y axis, so the perpendicular line has a slope of o, a horizontal line. this horizontal line goes through C(8,10), so the equation is y=10
use the same method, slope of AC: (10-3)/(8-1)=1, so the perpendicular line from B to AC has a slope of -1. y=-x+b
Now use the point B(1,12) to find b: 12=-1+b =>b=13

so the equation for this line is y=-x+13

Step two: solve the system of equations: y=10
y=-x+13
we get x=3, y=10, which are the coordinates of the orthocenter.

I've also found the equation of the third line, which is y=(7/2)x-1/2, the point (3,10) is also on this line. So it works!

a plane takes off at 6 am, traveling north at 270 mph. a jet takes iff at 7 am, traveling north at 460 mph. at what time will the jet overtake the plane?

Answers

Remember the distance-rate-time f[tex]t = 0.704 hrs[/tex]ormula:
[tex]d=rt[/tex]

Now, if the jet overtakes the plane, then at some point their distances will be the same. This means their rate * time will be equal.

Let's call the rate for the first plane, r1, and the rate for the second plane, r2. If we set time as t, then we can create ourselves a formula. However, we have to add one to the time of the first plane since it leaves one hour earlier. In the end, we should have something like this:
[tex]r_{1}(t+1)= r_{2}t [/tex]

If you plug in the values, you should get:
[tex]t = 0.704h[/tex]

I need to find the LCD or LCM for this equation I Also need with n is please help ... 3/4n-18=1/4n-14

Answers

3/4n - 18 = 1/4n - 14

We need to isolate "n"

So, add 18 to both sides.

3/4n = 1/4n - 14 - 18

Then, subtract 1/4n from both sides.

3/4n - 1/4n = -14 - 18

*Note : Since "n" has the same denominator (bottom number in a fraction), then we simply need to look at the top numbers (numerators) and simplify those.

Simplify.

2/4n = -32

Then, multiply both sides by 4 so that we get rid of fractions.

4 · 2/4n = -32 · 4

Simplify.

2n = -128

Now, divide both sides by 2.

2 ÷ 2n = -128 ÷ 2

Simplify.

n = -64

what expression is equivalent to 2.2-2.5?

Answers

Hi Camrynb10705oxknsv!
So let's take a look at the answers they give. A is 2.5 - 2.2 and all that is is switching the numbers so that isn't right. B they do addition instead of subtraction so that can't be right. C they do 2.2 + (-2.5) and when you add a negative number it's like subtraction because a negative number is under 0 and so your adding a number under 0 so you go down. So the answer is C.
If you need me to explain it different let me know. Hope this helps!

The answer is C. How we know:
The origional expression would equate to -0.3
The reason A is incorrect is that you can not change the order of subtraction. This answer equates to 0.3.
The reason B is incorrect is that adding is not the same as subtracting. This answer equates to 4.7.
The reason D is incorrect is that subtracting a negative is the same as adding. This would equate to 4.7
The reason C is correct is that adding negative is the same as subtracting. This would equate to -0.3.

It is given that:

The expression is:

p = 6s

To solve the above expression in terms of p make the subject as s

As we know, the arithmetic operation can be defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.

Divide by 6 on both sides:

p/6 = 6s/6

p/6 = s

s = p/6

Thus, the expression can be written in terms of p after making the subject as s the expression is s = p/6.

Fashion Phreddy buys 5 shirts and 3 ties for 91 on the bargain bus. Billy joe bob buys 8 shirts and 5 ties for 146. If all the shirts sold for the same price and each ties were priced identically. How much was each shirt and tie.

Answers

Assume that the price of the T-shirt is x and the price of the tie is y.

Fashion Phreddy buys 5 shirts and 3 ties for 91. This means that:
5x + 3y = 91 .........> equation I
5x = 91-3y
x = 18.2 - (3/5) y ..........> equation II
Billy joe bob buys 8 shirts and 5 ties for 146. This means that:
8x + 5y = 146 ...........> equation III

Substitute with equation II in equation III:
8(18.2 - (3/5) y) + 5y = 146
145.6 - 4.8y + 5y = 146
0.2y = 0.4
y = 2
Substitute in equation II to get the value of x:
x = 18.2 - (3/5) (2) = 17

Based on the above calculations:
price of T-shirt = x = 17
price of tie = y = 2
