Answer:
Option B
Step-by-step explanation:
I can't do the 'figure question' because it lacks info, but I can answer the point-slope question.
Point-slope form is: [tex]y-y_1=m(x-x_1)[/tex]
'm' - slope
'(x1, y1)' - point
We are given the slope of 3 and the point (-1, 5).
Replace 'x1', 'y1', and 'm' with the appropriate values.
[tex]y-y_1=m(x-x_1)\rightarrow \boxed{y-5=3(x+1)}[/tex]
Option B should be the correct answer.

Which expression entered into a graphing calculator will return the probability
that a data value in a normal distribution is between a z-score of -0.18 and a
Z-score of 1.99?
A. normalcdf(0.18, 1.99)
B. normalcdf(-1.99,0.18)
C. normalcdf(1.99, 0.18)
O
D. normalcdf(-0.18, 1.99)
The expression that returns the probability that a data value in a normal distribution is between a z- score of -0.18 and a z-score of 1.99 is (d) normalcdf(-0.18, 1.99)
How to determine the expression?To calculate the probability between two z-scores is to calculate the area between the z-scores.
This is done using the following syntax:
normalcdf(lower bound, upper bound)
From the question, the lower and the upper z-scores are -0.18 and 1.99
So, the formula would be normalcdf(-0.18, 1.99)
Hence, the expression is (d)

what is the amount of the discount
Answer:
The discount is $3.75.
Step-by-step explanation:
You can cross-multiply and divide: the original price can be multiplied by the percent off and then divide it by 100.
12.5×30=375
375÷100=3.75 which is the amount of the discount.
Choose the graph that displays the solution to the system of equations.
x = y - 2
y-8 =
2
Answer:
The first graph is the solution to:
x = y - 2 (blue line)
y-8 = -1/2x (red line)
where the solution is (4,6)
The second graph is the solution to:
x = y - 2 (blue line)
y-8 = -2x (red line)
where the solution is (2,4)
Step-by-step explanation:
The second equation is not clear. From the figures, the possible functions are: y-8 = -1/2x and y-8 = -2x.
To graphically solve a system you have to draw each line on the plane and look at the intersection point.

the table shows the heights of 40 students in a class calculate an estimate for the mean height of the students
Answer:
For mean
To show the mean of height measures for 40 students, you need to write-out exactly 40 heights into a calculator and add them up.
Then divide that total number by 40.
Step-by-step explanation:
Eg for 4 students
5 , 5.1, 5.2, 5.7 = 21ft
21/4 = 5.25ft.
Apply the same method but use 40 measures in addition for calulator or long addition. Then divide by 40.

When you reflect it over the x-axis you have to change the coordinates of each number.
Answer:
B. (1, -1), (1, -4), (3, -1)
Step-by-step explanation:
If a triangle is reflected across the x-axis, it's y coordinate values will become negative or positive if it's already negative. It uses the rule (x, -y)
(1, 1) → (1, -1)
(1, 4) → (1, -4)
(3, 1) → (3, -1)
Only B. (1, -1), (1, -4), (3, -1) is correct.

Given: BC ⊥ CA , Prove: m∠A+m∠B=90°
Answer:
With points A, B and C a right triangle is formed.
Given that BC ⊥ CA, then m∠C = 90°.
The addition of the angles of a triangle is equal to 180°, therefore:
m∠A + m∠B + m∠C = 180°
Substituting with m∠C = 90°:
m∠A + m∠B + 90° = 180°
m∠A + m∠B = 180° - 90°
m∠A + m∠B = 90°
PLEASE ANSWER ASAP AND PROVIDE EXPLANATION! A copy machine is set up to enlarge an original in the ratio 2:3. What is this enlargement in percent?
Answer:
50%
Step-by-step explanation:
Enlarging it in the ratio 2:3 means dividing it by 2 and multiplying it by 3.
Lest's pretend the original size was 100 in. 100/2x3=150
So in this case we enlarged it by 50 in. which is 50% of 100.
So, the enlargement as a percentage is 50%
Answer:
50% more
3-2=1
1/2=0.5
0.5=50%
You can also double check by adding half of two and checking if it is 3
2 x 0.5 = 1
2 + 1 = 3
50% increase

Using the formula given below for this
=> [tex](n-2)*180 = measure of interior angles[/tex]
=> (n-2)*180 = 2880
Dividing both sides by 180
=> n-2 = 16

1. Now consider equations of the form , where a, b, and c are all positive integers and . (a) Create an equation of this form that has 7 as a solution and an extraneous solution. Give the extraneous solution. (b) What must be true about the value of to ensure that there is a real number solution to the equation? Explain.
a) To create an equation
X+X =7
so what's X over here is
7² = x²
X=3.5
b) Real numbers are mixture of irrational and rational numbers so √5 and √6 are irrational where as 5 and 6 are not but they two are equal to each other.
Explaining the equation:
√5 +√6 = √11
5 +6 = 11
√11 =11
√= 11 ÷ 11
√= 1
So if root is 1 then -1 is -√

(a)
[tex]\frac{xPR}{XZ}[/tex] = [tex]\frac{PQ}{XY}[/tex] , substitute values
[tex]\frac{6.5}{XZ}[/tex] = [tex]\frac{7.2}{18}[/tex] ( cross- multiply )
7.2XZ = 117 ( divide both sides by 7.2 )
XZ = 16.25 cm
---------------------------------------
(b)
[tex]\frac{QR}{YZ}[/tex] = [tex]\frac{PQ}{XY}[/tex] , substitute values
[tex]\frac{QR}{17}[/tex] = [tex]\frac{7.2}{18}[/tex] ( cross- multiply )
18QR = 122.4 ( divide both sides by 18 )
QR = 6.8 cm

A line passes through the point (0,6) and is parallel to the line with the equation y =
1/5X - 5. What's the equation of the line?
O A) y = 1/5x + 6
OB) y = -5x + 6
C) y = 1/5* - 6
OD) y=1/5X
Answer:
A
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{1}{5}[/tex] x - 5 ← is in slope- intercept form
with slope m = [tex]\frac{1}{5}[/tex]
Parallel lines have equal slopes, thus parallel line has slope of [tex]\frac{1}{5}[/tex]
The line crosses the y- axis at (0, 6) ⇒ c = 6
y = [tex]\frac{1}{5}[/tex] x + 6 ← equation of parallel line → A
the equation of the line that passes through the point (0,6) and is parallel to the line with the equation y = 1/5X - 5 is y = 1/5x +6.
What is a Linear equation?A linear equation is an algebraic equation of the form y=mx+b, where m is the slope and b is the y-intercept, and only a constant and a first-order (linear) term are included. Sometimes, the aforementioned is referred to as a "linear equation of two variables," with y and x serving as the variables.
Given A line passes through the point (0,6) and is parallel to the line with the equation y = 1/5X - 5
Since the two lines are parallel to each other
thus, their slope would be equal
Slope intercept form of the Second line:
y = 1/5x + c
Given that line passes through (0, 6)
From above equation
6 = 1/5* 0 +c
Hence, c = 6
therefore, the equation of the line y = 1/5x +6.

Answer:
1st Choice
Step-by-step explanation:
The fastest way to do this is by thinking of translations. If you are trying to move it left or right, it will be inside the cube root. If you want to move it vertically, it will be outside the root. In the graph, the child function is moving from the parent function to the right. This means we can eliminate choices C and D. We are left with A and B. A is the right choice because you take the negative of the direction you want to move in. Thus, you have your answer.

Find the value of x in each case.
Answer:
x = 22°
Step-by-step explanation:
Given corner URV = x and because of symmetry of Z-corners, that corner by definition is the same as corner DVR.
So corner SVR = V = x
R = 44°
S = 5x + 4°
V = x
In any triangle the three corners add up to 180°
Combine all this info and you get:
44 + 5x + 4 + x = 180
Solve for x (means write as x =...)
5x + x = 180 - 4 - 44
6x = 132
x = 132/6
x = 22°
