What value of x makes this equation true? 2(4x-3) - 8= 4+2x
Answer:
What value of x makes this equation true? 2(4x-3) - 8= 4+2x HERE YOU GO!!
Step-by-step explanation:
We need to eliminate one of the variables to solve the other.
4x+5y = 8
2x-3y = 18
I will multiply the second equation by -2.
-2*(2x-3y = 18)
-4x + 6y = -36 and then add the two equations
4x + 5y = 8
-4x + 6y = -36
+ adding here
11y = -24
y = -24/11
substitute x in one of the equations to find y.
2x-3y=18
2x - (3*-24/11) = 18
2x = 126/11
x = 126/22

Find the measures of the sides of triangle DEF, then classify it by its sides. YOU MUST SHOW WORK TO GET CREDIT!
D(-2, 3), E(5, 5), F(-4, 10)
Answer:
FE = 10.30
ED = 7.62
FD = 7.28
Step-by-step explanation:
First, use coordinate system to draw a square that each angle of triangle reach the sides of the square, then use Pythagoras theory to find the length of the sides(c^2=a^2+b^2)
FE = root(9^2+5^2) = root(106) = 10.30
ED = root(3^2+7^2) = root(58) = 7.62
FD = root(2^2+7^2) = root(53) = 7.28

What is the slope of the two points (-2,7) and (4,-8)
Answer:
-15/6
Step-by-step explanation:
If you look at the first number in each point, the x coordinate, you see the 2nd point is 6 forward from the 1st point. Now the 2nd number is the y coordinate, and you can see it goes down 15 from the 1st coordinate. So y/x is the slope.
Answer: -2 1/2
Step-by-step explanation:
Slope= Yb-Ya/Xb-Xa
In this case= (-8-7)/(4- -2)
This equals -15/6
Simply to -2 1/2
State the domain of f•g. Then find f•g, including any additional restrictions necessary on the domain of the composition
Answer:
Answer is option A
Step-by-step explanation:
The required function [f o g(x)] is -7/√(x + 3).
The domain of the function [f o g(x)] > - 3.
What is a function?A function is the relation between two sets. The first one is called domain and the second one is called range.
Given, f(x) = - 7/x
g(x) = √(x + 3)
Therefore, f o g(x)
= f[g(x)]
= f[√(x + 3)]
= -7/√(x + 3)
Now, the domain of f o g(x) > - 3.

Help plsssss!!!!!!!!!!!!!
Answer:
The second option
Step-by-step explanation:
A bag had 7 orange rocks , 6 green rock , 1 white rock ,7 black rocks , and 2 yellow you randomly pull a rock from the bag ,keep it out , and then pull out another one .
What is the probability of getting a yellow rock and then a n orange rock ?
Answer:
[tex]Probability = \frac{7}{253}[/tex]
Step-by-step explanation:
Given
[tex]Orange = 7[/tex]
[tex]Green = 6[/tex]
[tex]White = 1[/tex]
[tex]Black = 7[/tex]
[tex]Yellow = 2[/tex]
Required
Probability of selecting a yellow then orange rock
From the question, we understand that the probability is that of without replacement.
Since the yellow, is first picked.
We need to determine the probability of picking a yellow rock, first.
[tex]P(Yellow) = \frac{n(Yellow)}{Total}[/tex]
[tex]P(Yellow) = \frac{2}{7 + 6 + 1 + 7 + 2}[/tex]
[tex]P(Yellow) = \frac{2}{23}[/tex]
The rock has reduced by 1;
Next is to determine the probability of picking an orange rock
[tex]P(Orange) = \frac{n(Orange)}{Total - 1}[/tex]
[tex]P(Orange) = \frac{7}{7 + 6 + 1 + 7 + 2- 1}[/tex]
[tex]P(Orange) = \frac{7}{22}[/tex]
The required probability is calculated as thus:
[tex]Probability = P(Yellow) * P(Orange)[/tex]
[tex]Probability = \frac{2}{23} * \frac{7}{22}[/tex]
[tex]Probability = \frac{14}{506}[/tex]
[tex]Probability = \frac{7}{253}[/tex]
Determine the zeros or roots of each function or equation. You can use the quadratic equation if you need to.
