What is the solution of the system of equations? -4x+3y=-12 -2x+3y=-18
*Note: I believe it has no solution, but I would like to make sure. Thank you all for your help.
Answer:
Step-by-step explanation:
I've enclosed a graph to show you that there is one solution.
-4x + 3y = - 12
- 2x + 3y = - 18 Subtract
-2x = 6 Divide by - 2
-2x/-2 = 6/-2
x = - 3
- 4x + 3y = - 12
-4(-3) + 3y = - 12
12 + 3y = - 12
3y = - 12 - 12
3y = - 24
3y/3 = - 24/3
y = - 8
Which is exactly what the graph shows.
You can tell immediately that this has 1 or more solutions just by looking at the number in front of x and y in each each equation.
It's always a good idea to graph a question like this one. Desmos is a pretty good tool to use if you don't have a graphing calculator.
The y's are the same so you are 1/2 way home in saying what you did.
The x's are different so that means you have at least 1 solution.
The area of a triangle is 92 square inches. The base is 23 inches. What is the height in inches? Do not include units in your answer.
Answer:
34,5 ?? I am not good at this but I did 92-23 that's 69 ÷ 2 = 34.5 ?
Answer:
Step-by-step explanation:
We can use the formula for the area of a triangle, to help us find the height:
Area=12⋅b⋅h
Using the formula for area, we can solve for the height by plugging in the information we have about the area and the base:
92=12⋅23⋅h
Isolate h by multiplying both sides by 2 and dividing both sides by 23.
hh=2⋅9223=8
The height is 8 inches.

How much money is 15% of $ 14.99
Answer:
The discount is $2.25 and the final price will be $12.74
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 14.99 × 15/100
Discount = 14.99 x 0.15
You save = $2.25
Final Price = Original Price - Discount
Final Price = 14.99 - 2.2485
Final Price = $12.74
hope this helps and is right. p.s. i really need brainliest :)
Answer:
$12.74
Step-by-step explanation:
15% of 14.99 dollars
14.99-2.25=12.74
Final answer=12.74 dollars

-3/8 divided by -1/4 equals
Answer:
3/2 or 1.5 or 1 1/2
Step-by-step explanation
To divide, you must switch the -1/4 to its reciprocal which is -4/1 and then multiply the fractions (-3/8 * -4/1) and since negative - negative = positive. It's a positive.

Explain how to find mode, range, and mean
Step-by-step explanation:
The mean is the usual average, so add all of the numbers and then divide.
The mode is the number that is repeated more often than any other.
The range is the largest value and smallest value subtracted.
Answer:
Answer bellow
Step-by-step explanation:
To find mean(average) get all the numbers and and add them together after devide the added number by the number of numbers
To find mode rewrite all the numbers and look for numbers that are repeating (it can be more than one)
To find range take the biggest number from the data set and subtract it from the smallest number in the data set

Sophie needs to determine the amount of water that will fit into her new vase, shown below.
Which combination of geometric shapes can she use to best estimate the vase's volume?
A cone and a hemisphere
A cylinder and a sphere
A truncated cone and a sphere
A truncated pyramid and a hemisphere
Answer:A truncated cone and a sphere
Step-by-step explanation:
I just did it.
The combination of geometric shapes can she use to best estimate the vase's volume is a truncated cone and a sphere.
Sophie needs to determine the amount of water that will fit into her new vase, as shown below.
What is the volume?
Volume is a scalar quantity expressing the amount of three-dimensional space enclosed by a closed surface.
We have to determine the combination of geometric shapes can she use to best estimate the vase's volume.
Therefore the combination of geometric shapes can she use to best estimate the vase's volume is a truncated cone and a sphere.

3. Write the equation of the circle with a center at (-6, 1) and an area of 7n.
A Q(x + 6)^2 + (y - 1)^2 = 14
B (x - 6)^2 + (y + 1)^2 = 49
C (x + 6)^2 + (y - 1)^2 = 49
D (x + 6)^2 + (y - 1)^2 = 7
E (x - 6)^2 + (y + 1)^2 = 7
Answer:
D [tex] (x +6) ^2 +(y-1)^2 =7 [/tex]
Step-by-step explanation:
Center of the circle (h, k) = (-6, 1)
Area of the circle [tex] =\pi r^2 [/tex]
[tex] 7\pi=\pi r^2 [/tex]
[tex] \frac {7\pi}{\pi} =r^2 [/tex]

Radius [tex] r=\sqrt {7}[/tex]
Equation of circle in center radius form is given as:

Plugging the values of h, k and r in the above equation, we find:

A scale model of an object has a scale of 1cm : 2ft. The actual object is 11 feet tall. How tall is the model?
Given:
The scale model of an object has a scale of 1cm : 2ft.
The actual object is 11 feet tall.
To find:
The height of the model.
Solution:
It is given that the scale model of an object has a scale of 1cm : 2ft and the actual object is 11 feet tall.
Let the height of the model be x cm.
[tex]\dfrac{x\ cm}{11\ ft}=\dfrac{1\ cm}{2 \ ft}[/tex]
[tex]x\ cm=\dfrac{1 \ cm\times 11\ ft}{2 \ ft}[/tex]
[tex]x\ cm=5.5\ cm[/tex]
Therefore, the model is 5.5 cm tall.

3/4 Ravi is as tall as Sam, Mike is as tall as 5/3 Ravi. Find the ratio of Mike's height to Sam's height.
Answer: The ratio of Mike and Sam Heights are S:M=5:4
Step-by-step explanation:
Ravi is 3/4 as tall as Sam.
Consider the equation is 3/4 *R=S
Mike is 5/3 as tall as Ravi.
Then, the equation is 5/3 *M=R
Solve the two equation to find ratio of mikes and sam height.
3/4*R=S Eq(1)
Rearranging eq (1) for R
R=4/3 *S Eq(3) made from eQ (1)
R=5/3*M Eq(2)
Comparing Eq 2 &3 equations
4/3*S=5/3*M
S/M=(5/3)*(3/4)
S/M=5/4

You randomly choose one of the chips. Without replacing the first chip, you choose a second chip. Find
the probability of choosing the first chip, then the second chip.
White and not a Green
Answer:
probability = 0.07777
Step-by-step explanation:
there are 10 chips
white 1
red 4
green 2
blue 3
the probability of choosing the W chip is 1/10 or 0.10
now there are 9 chips left (the first chip was not replaced)
the probability of choosing a non-green chip is (9-2)/9 = 7/9 = 0.7777
so now I THINK you multiply the two probabilities to get the total probability
probability = 0.1 ·0.7777
probability = 0.07777 which makes sense it has to be less than 0.1
Answer:
1/15
Step-by-step explanation:
2/10 x 3/9= 6/90
6 divided by 6
90 divided by 6
=1/15
