Are the triangles similar why or why not?
Answer: No, the triangles are not similar. They aren't even triangles.
Step-by-step explanation: A is a diamond, which cannot be considered a triangle until it is split in half. 8 and 9 would be a triangle if the diamond wouldn't have been there. B and C is a parallelogram.

The scatter plot shows the number of minutes people had to wait for service at a restaurant and the number of staff available at the time.
A line that models the data is given by the equation $$, where $$ represents the wait time, and represents the number of staff available.
The slope of the line is -1.62. What does this mean in this situation?
it means that the scatter plots are off the chart
Is a slope of 1.62 realistic in this context?
no because it is not a coordinate and there isn't any decimals in the wait time
The $$-intercept is $$. What does this mean in this situation?
it means there's more waiting time
Is a $$-intercept of $$ realistic in this context?
no because when you try to find it it goes off the graph and isnt calculable.
Edit my response f
The slope of a linear regression is the rate of change of the line of the best fit
The interpretation of the slope is that the wait time per staff is 1.62 minutesThe slope value is realisticHow to interpret the slopeThe linear regression is given as:
[tex]y = -1.62x + 18[/tex]
Where
y represents the wait timex represents the number of staffUsing the above representations, the slope means that the wait time per staff is 1.62 minutes
Also, the slope value is realistic because time can be measured in decimals

Answer:
y=mx+b
The slope of a linear function can be calculated by dividing the difference between y-values by the difference in corresponding x-values of any two points on the line. The slope and initial value can be determined given a graph or any two points on the line.
For example if you want to use the points from the line (-2,4) (7,-8) from the graph given to you you use the equation: m=(y2-y1)/(x2-x1) substitute the values: m= -8-4 / 7-(-2) = -1.3333
So the slope equals -1.3
The equation of the line is y = -1.3x + 2

what is the equation of a vertical line that passes through (3, -10)
[tex]\qquad \qquad\huge \underline{\boxed{\sf Answer}}[/tex]
A vertical line is always parallel to y - axis, I.e the x - coordinates of the points on the line never changes
Therefore, the equation of the line will be ~
[tex]\qquad \sf \dashrightarrow \: x = 3[/tex]
And on this line, for each value of y, there is same value of x ~
The required equation of a vertical line that passes through (3, -10) is x = 3
Equation of a lineThe equation of a line in point slipe form is expressed as:
y - y1 = m(x-x1)
The equation of a vertical line is given as x = a
The value of a is the x coordinate of the given point. Hence the value of a = 3
The required equation of a vertical line that passes through (3, -10) is x = 3

Six times a number is 14 less than the opposite of that number. What is the number?
Answer:
2
Step-by-step explanation:
6 x 2 = 12
12 is less than 14
Question :
Six times a number is 14 less than the opposite of that number. What is the number?Solution :
Let's assume the number as " x "
According to the question :
Six times a number is 14 less than the opposite of that number.We already assumed that the number is x. So, opposite of the number would be -x.
[tex]\qquad \sf \: { \dashrightarrow 6x= - x-14}
[/tex]
Now, let's solve this equation :
[tex]\qquad \sf \: { \dashrightarrow 6x + x= -14}
[/tex]
Combining the like terms :
[tex]\qquad \sf \: { \dashrightarrow 7x = - 14}
[/tex]
Then divide both sides by 7 :
[tex]\qquad \sf \: { \dashrightarrow \dfrac{7x}{7} = - \dfrac{14}{7} }
[/tex]
[tex]\qquad \sf \therefore \: \bf{{ x= -2}}
[/tex]
Therefore, the required number is -2 .

Area would be the width times length and for the areas as the sum you would just calculate the area of the smaller rectangles and add them.
Prove parallel lines have the same slope. Use lines f and g. Line g is a vertical translation of line f.
Please help
Answer:
The slope of both lines is 1/4.
Step-by-step explanation:
Line g is a vertical translation of line f so they are parallel. Now find the slope of each line.
Line f joins points (-2, 1) and (2, 2), so its slope is (2 - 1) / [2 - (-2)] = 1/4.
Line g joins points (-2, -1) and (2, 0), so its slope is [0 - (-1)] / [2 - (-2)] = 1/4.
The two parallel lines have the same slope.
Answer:
(1)
since a translation of a line segment is its rigid movement, vertically or horizontally.
line 's' is parallel to line 'r' since it is a translation of line 'r' 'e' units vertically ( clearly we could see that the point P' corresponding to point P in line r is shifted 'e' units upward and point Q' in line 's' is formed by shifting corresponding point Q of line 'r' e units upward).
(2)
the slope of a line is defined as the change in y-coordinates to the change in x-coordinates of the points on that line.
slope of line r=slope of line segment PQ.
coordinates of P=(m,n) and Q=(j,k)
slope of line r=slope of PQ=
k-n ÷ j-m
(3)
the slope of line s= slope of line segment P'Q'
slope of line s=slope of P'Q'=
k+e- (n+e) ÷ j-m
=
k-n ÷ j-m
(4)
as line q is a vertical translation of line 's' 3 units down.
and P'' is the image of P'.
so coodinates of P''= (m,n+e-3)
In 5 years' time, Kate's father will be 3 times as old as Kate. Four years ago, her father
was 6 times as old as her. Find their present ages.
Answer: Kate = 40/3 Her father = 50
Step-by-step explanation:
Let Kate's age in the present be K
And Kate's father's age in the present be F
3(K+5) = F+5
6(K-6) = F-6
Rearrange the first equation to get
3K+15 = F+5
3K+10 = F
Substitute that into the second question
6K-36 = 3K+10-6
3K = 40
K = 40/3
So F = 3*40/3+10 = 50
Niah earns $7. 25 per hour at her part-time job that she works at 18 hours per week. To earn some extra money, Niah helps her friend out with her dog walking service. It is possible to walk more than one dog at a time, and Niah’s friend pays her $9 per dog for each half hour walked. Niah walks dogs on 3 different days this week, as listed below. What is the total amount of earnings Niah had this week? Monday: 3 dogs for 0. 5 hours Wednesday: 2 dogs for 0. 5 hours and 1 dog for 0. 5 hours Thursday: 2 dogs for 1 hour a. $175. 50 b. $195. 75 c. $202. 50 d. $220. 50.
Answer:
The answer is D.
Step-by-step explanation:
The job would give her $130.50 dollars per week. Basically m= 7.25h.
Then, Monday was $27 dollars. Wednesday was $27 as well. Thursday was $36 also. So, we just needed to add this all together. You would get $220.50. So, it would be D!
Graph h(x)=2sin(2x)−3.
Use 3.14 for π.
Use the sine tool to graph the function. The first point must be on the midline and the second point must be a maximum or minimum value on the graph closest to the first point.
Answer:
Step-by-step explanation: i took the test.
The first point is ta x= - 3.
The function h(x) has a maximum value.
The graph of the function h(x) is given below.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = 2x + 1
f(1) = 2 + 1 = 3
f(2) = 2 x 2 + 1 = 4 + 1 = 5
The outputs of the functions are 3 and 5
The inputs of the function are 1 and 2.
We have,
h(x) = 2 sin(2x) - 3
The first point is at x = -3.
h'(x) = 4 cos(2x)
h''(x) = -8 sin(2x)
This means,
h(x) has a maximum value on the graph.
The graph of h(x) is given below.
Thus,
h(x) has a maximum value and the graph is given below.
