Answer:
3x + 4y = 8
Step-by-step explanation:
Slope intercept form: Standard form:
y = mx + b Ax + By = C
y = -3/4x + 2 y = -3/4x + 2 add 3/4x to both sides
3/4x + y = 2 multiply by 4
3x + 4y = 8
The following is a random sample of the annual salaries of high school counselors in the United States. Assuming that the distribution of salaries is approximately normal, construct a 95% confidence interval for the mean salary of high school counselors across the United States. Round to the nearest dollar.

write the coordinates of the vertices after a reflection over the line x=-2
d(-10,0)
e(-10,2)
f(-5,2
g(-5,0)
Given:
The vertices are d(-10,0), e(-10,2), f(-5,2) and g(-5,0).
To find:
The coordinates of the vertices after reflection over the line x=-2.
Solution:
If figure reflected over the line x=a, then
[tex](x,y)\to (2a-x,y)[/tex]
Here, the figure is reflected over the line x=-2, then
[tex](x,y)\to (2(-2)-x,y)[/tex]
[tex](x,y)\to (-4-x,y)[/tex] ...(i)
Now,
For point d,
[tex](-10,0)\to (-4-(-10),0)[/tex]
[tex](-10,0)\to (-4+10,0)[/tex]
[tex](-10,0)\to (6,0)[/tex]
Similarly,
For point e,
[tex](-10,2)\to (-4-(-10),2)=(6,2)[/tex]
For point f,
[tex](-5,2)\to (-4-(-5),2)=(1,2)[/tex]
For point g,
[tex](-5,0)\to (-4-(-5),0)=(1,0)[/tex]
Therefore, the coordinates of vertices after a reflection over the line x=-2 are d prime (6,0), e prime (6,2), f prime, (1,2) and g prime (1,0).
Solve the equation 3.6g + 2 = 1.6g + 8.
a. Find the value of g.
Answer:
Step-by-step explanation:

Cameron wants to buy a skateboard. he has $89, Which is $17 more than he needs. Which equation can be used to determine how much the skateboard costs
Answer:
The answer to this question is $72. The equation is x + 17 = 89
Step-by-step explanation:
Equation: x + 17 = 89
Cameron has $89 so 89 would go behind the equal sign.
He has 17 dollars more than he needs. Whenever more is used that usually indicates that it will be a plus sign. So we will do + 17 = 89.
Finally we need to add the x to complete the equation. This will be shown as x + 17 = 89.
If you solve this equation it will equal x = 72.
If this helped you please subscribe to The Game Rater. Thank you.
Answer:
89-17
Step-by-step explanation:
To find how much Cameron’s skateboard costs you need to take away 17 from your starting amount as you have more. Meaning we subtract the 17 to find how much the skateboard costs.
A equals what?? Helpp
Answer:
<A = 143 degrees
Step-by-step explanation:
<A = <B
7x + 24 = 3x + 92
4x + 24 = 92
4x = 68
x = 17
then...
<A = 7(17) + 24
119 + 24
<A = 143 degrees
Answer:
then m<A=7×17+24=143
Step-by-step explanation:
7x +24=3x+92(corresponding angles )
7x_3x=92_24
4x=68
x=68÷4
x=17

How many units away are each of the points from the y-axis?
O 2

O 4
O 5
PLEASE HURRY
Answer:
A. 2
Step-by-step explanation:
Point A is on the y-axis is y = -2.
-2 is 2 units away from 0, which is the y-axis.
Point B also, on the y-axis, is y = 2.
2 is also 2 units apart from the y-axis, which is y = 0.
Therefore, both points are 2 units away from the y-axis.

Circle A is shown with a central angle marked 37 degrees and the radius marked 10 inches. Which of the following could be used to calculate the area of the sector in the circle shown above?
π(10in)237 over 360
π(10in)37 over 360
π(37in)210 over 360
π(37in)10 over 360
Answer:
π(10in)237 over 360
Step-by-step explanation:
i took the same test and got it right :)
The area of the sector of the circle is [tex]\frac{100\pi }{360} *37[/tex]
To understand more, check below explanation.
Area of the sector of the circle:To find the area of the sector of circle, we use formula,
[tex]Area=\frac{\pi r^{2} }{360} *\theta[/tex]
where r is radius of circle and [tex]\theta[/tex] is the central angle.
Given that, r = 10 inches, [tex]\theta[/tex] = 37 degrees.
Substitute above values in above formula.
[tex]Area=\frac{\pi (10)^{2} }{360} *37\\\\\\Area=\frac{100\pi }{360} *37[/tex]

Step-by-step explanation:
When the question asks for rate of growth in a linear equation, we are going to look for slope. Slope formula is (y2-y1)/(x2-x1). We are given the points (2,5) and (5,8).
Now we can plug them into our formula:
(5-8)/(2-5)
-3/-3
1
Therefore, our rate of growth, or slope, is 1.
