Which point is on the graph of the equation y = 2x - 5?(3, -1)
(2, -5)
(4, 2)
(2, -1)

Answers

Answer 1

Answer: The x in this equation is the first number in the brackets, and the result of the equation is the second number in the brackets. So all that needs to be done is to substitute x for 3, 2 and 4 and see which one has the correct answer.
3 X 2 = 6. 6 - 5 = 1 (3, 1)
2 X 2 = 4. 4 - 5 = -1 (2, -1)
4 X 2 = 8. 8 - 5 = 3 (4, 3)

The only one of those coordinates that are the same as any of the given answers are (2, -1). Therefore, that is the answer.

Answer:25

Step-by-step explanation:

Mr. Gonzales has only $42.50 to spend at a clothing store. He wants to buy a shirt that costs $29, including tax, and some bracelets that cost $4.50 each, including tax. Write an equation to determine x, the maximum number of bracelets Mr. Gonzales could buy. Equation _____________________. Solve the equation to determine the number of bracelets Mr. Gonzales could by. Show your work. Answer _____________________ bracelets

Answers

Answer: The equation is $29 + x*$4.50 = $42.50, and the solution is x = 3

Step-by-step explanation:

The data we have is:

Gonzales has $42.50

He wants to buy:

a shirt that costs $29

some bracelets that cost $4.50 each.

The equation that we need to solve is:

Total cost = money that Gonzales has.

The cost is $29 + x*$4.50

where x is the number of bracelets he can buy.

The equation that we need to solve is:

$29 + x*$4.50 = $42.50

to solve it we must isolate x:

x*$4.50 = $42.50 - $29 = $13.50

x = 13.50/4.50 = 3

So we have that Mr. Gonzales can buy a total of 3 bracelets.

y=4.5x+29 put y=0 so you can solve
0=4.5x+29 minus 29 on both sides to cancel it out
-29=4.5x divide by 4.5 on both sides to find x

Remi has two cone-shaped containers with the same diameter. He will place the smaller container inside the larger one. Before he does this, he wants to fill the larger container with water so that it will be completely full but won’t spill when he places the smaller container inside. The diameter of both containers is 12 cm. The height of the smaller container is 6 cm, and the height of the larger container is 18 cm.What volume of water must Remi put in the large container?

So,

All we have to do is subtract the smaller cone's volume from the larger cone's volume.

First, we will use the formula for the volume of a cone to find the volume of the larger cone.
$V_(1) = (1)/(3)\pi r^2h$

Substitute.
$V_(1) = (1)/(3)(3.14)(6)^2(18)$

Simplify exponents.
$V_(1) = (1)/(3)(3.14)(36)(18)$

Multiply. We will do the fraction last.
$V_(1) = (1)/(3)(113.04)(18)$
$V_(1) = (1)/(3)(2034.72)$
$V_(1) = 678.24\ cm^3$

Now, use the same formula and procedure to find the volume of the smaller cone.
$V_(2) = (1)/(3)\pi r^2h$

$V_(2) = (1)/(3)(3.14)(6)^2(6)$

Exponents first, and then multiplication, leaving the fraction last.
$V_(2) = (1)/(3)(3.14)(36)(6)$
$V_(2) = (1)/(3)(113.04)(6)$
$V_(2) = (1)/(3)(678.24)$
$V_(2) = 226.08\ cm^3$

Now, use this formula to find the answer:
$V_(2) - V_(1) = Ans$

And substitute the now known values.
$678.24 - 226.08 = Ans$
$452.16\ cm^3 = Ans$

An angle measures 65º. What is the measure of its supplement?

Answers

supplement=angles that add to 180
so x+y=180
one is 65
65+x=180
subtract 65 from both sides
x=115
the supplelmemnt is 115 degrees

the complement relateds to a right angle.

90-65=25 degrees
