Answer:
a) The new ordered pairs are X' (-3, -7), Y' (-2, -10), Z' (-5, -2)
b) The new ordered pairs are X' (6, 9), Y' (7, 12), Z' (4, 4)
Step-by-step explanation:
If the point (x, y) reflected across the x-axis, then its image is (x, -y), which means to reflect a point across the x-axis, change the sign of its y-coordinateIf the point (x, y) translated h units to the right and k units up, then its image is (x + h, y + k), which means add its x-coordinate by h and add its y-coordinate by k∵ X = (-3, 7), Y = (-2, 10), and Z = (-5, 2)
∵ The points reflected in the x-axis
→ Change the signs of the y-coordinates of the 3 points
∴ X' = (-3, -7), Y' = (-2, -10), and Z' = (-5, -2)
a) The new ordered pairs are X' (-3, -7), Y' (-2, -10), Z' (-5, -2)
∵ X = (-3, 7), Y = (-2, 10), and Z = (-5, 2)
∵ The points translated to be (x + 9, y + 2)
→ That means add the x-coordinates by 9 and y-coordinates by2
∴ X' = (-3 + 9, 7 + 2), Y' = (-2 + 9, 10 + 2), and Z' = (-5 + 9, 2 + 2)
∴ X' = (6, 9), Y' = (7, 12), and Z' = (4, 4)
b) The new ordered pairs are X' (6, 9), Y' (7, 12), Z' (4, 4)

Write the equation in slope intercept form y - 4=10(x-5)
Answers
Answer:
y = 10x - 46
Step-by-step explanation:
slope intercept form: y = mx + b
m is slope and b is y-intercept
given: y - 4 = 10(x-5)
1. distibute 10
y - 4 = 10x - 50
2. we need to get y by itself so bring -4 to other side
y = 10x - 50 + 4
y = 10x - 46
slope-intercept form is [tex]y=mx+b[/tex]
[tex]y=10(x-5)+4[/tex] ↣ We move -4 to another side and become positive number.
[tex]y=(10x-50)+4[/tex] ↣ Distribute 10 inside the brackets.
[tex]y=10x-50+4\\y=10x-46[/tex] ↣ Then we get the slope-intercept form.
Thus, the answer is [tex]y=10x-46[/tex]

A regular pentagon is created using the bases of five congruent isosceles triangles, joined at a common vertex. A regular pentagon is shown. Lines are drawn from each point to a point in the center to form congruent isosceles triangles. The lengths of all lines are congruent. The total number of degrees of all center angles is 360 degrees. The total number of degrees in the center is 360°. If all five vertex angles meeting at the center are congruent, what is the measure of a base angle of one of the triangles?
Answers
Answer:
Each base angle of one triangle is 54°
Step-by-step explanation:
Since the angles meeting in the center are congruent and all form 360° then it means each angle will be 360°/5 = 72°(since we have 5 angles).
Since they are all isosceles triangles, it means two base angles are equal and can be gotten by:
(180 – 72)/2 = 54°.
Each base angle of one triangle is 54°
The measure of a base angle of one of the triangles is 54°.
Given that,
A regular pentagon is created using the bases of five congruent isosceles triangles, joined at a common vertex.
A regular pentagon is shown. Lines are drawn from each point to a point in the center to form congruent isosceles triangles.
The lengths of all lines are congruent. The total number of degrees of all center angles is 360 degrees.
The total number of degrees in the center is 360°. If all five vertex angles meeting at the center are congruent,
We have to determine,
What is the measure of the base angle of one of the triangles?
According to the question,
The lengths of all lines are congruent. The total number of degrees of all center angles is 360 degrees.
The total number of degrees in the center is 360°. If all five vertex angles meeting at the center are congruent,
The angles meeting in the center are congruent and all form 360°.
then it means each angle will be,
[tex]=\dfrac{360}{5}\\\\= 72 \ degree[/tex]
There are 5 angles.
Therefore,
All isosceles triangles, it means two base angles are equal and can be,
[tex]=\dfrac{180-72}{2}\\\\=\dfrac{108}{2}\\\\=54[/tex]
Hence, Each base angle of one triangle is 54°

Vince borrows $900 to buy a couch. He will pay off the loan by paying 1.5% simple interest for 2 years. Vince incorrectly calculates the amount he will pay back using the expression below. What is the correct amount Vince will pay back altogether?
Answers
Answer:
the correct amount that Vince have to pay back altogether is $927
Step-by-step explanation:
The computation of the correct amount that Vince have to pay back altogether is as follows:
As we know that
Amount = Principal + Principal × rate of interest × time
= $900 + $900 × 0.015 × 2
= $900 + $27
= $927
Hence, the correct amount that Vince have to pay back altogether is $927

Ax + By = C ( A is a positive integer and B, C are integers )
Given
y - 2 = - [tex]\frac{1}{3}[/tex] (x + 6) ← distribute
y - 2 = - [tex]\frac{1}{3}[/tex] x - 2 ( add 2 to both sides )

After being dilated by a scale factor 1.5?
Answers
Given:
The given figure is dilated by a scale factor 1.5.
To find:
The coordinates of B' and C'.
Solution:
If a figure is dilated by a scale factor k at point (a,b), so the rule of transformation is
[tex](x,y)\to (k(x-a)+a,k(x-b)+b)[/tex]
From the given figure it is clear that A(3,-3), B(-2,2) and C(-3,-5).
The figure is dilated by a scale factor 1.5 at point A(3,-3), so the rule of transformation is
[tex](x,y)\to (1.5(x-3)+3,1.5(x-(-3))+(-3))[/tex]
[tex](x,y)\to (1.5(x-3)+3,1.5(x+3)+(-3))[/tex]
[tex](x,y)\to (1.5(x)-4.5+3,1.5(x)+4.5-3)[/tex]
[tex](x,y)\to (1.5x-1.5,1.5x+1.5)[/tex]
Using this rule, we get
[tex]B(-2,2)\to B'(1.5(-2)-1.5,1.5(2)+1.5)[/tex]
[tex]B(-2,2)\to B'(-3-1.5,3+1.5)[/tex]
[tex]B(-2,2)\to B'(-4.5,4.5)[/tex]
And
[tex]C(-3,-5)\to C'(1.5(-3)-1.5,1.5(-5)+1.5)[/tex]
[tex]C(-2,2)\to C'(-4.5-1.5,-7.5+1.5)[/tex]
[tex]C(-2,2)\to C'(-6,-6)[/tex]
Therefore, the coordinates of B' and C' are B(-4.5,4.5) and C'(-6,-6).

On a coordinate plane, an absolute value graph has a vertex at (1, 3). Which equation represents the function graphed on the coordinate plane? g(x) = |x + 1| + 3 g(x) = |x + 3| – 1 g(x) = |x – 1| + 3 g(x) = |x + 3| + 1
Answers
Answer: g(x)= |x-1| + 3
Step-by-step explanation: the |x-1| means you need to move the vertex to the right by one and the +3 means you must move the vertex up by three
The equation that represents the function on a coordinate plane is [tex]g(x) =|x - 1| + 3[/tex]
The vertex is given as:
[tex](h,k) = (1,3)[/tex]
An absolute function is represented as:
[tex]y = a|x - h| + k[/tex]
Substitute 1 for h, and 3 for k
[tex]y = a|x - 1| + 3[/tex]
Assume that the value of (a) is 1
[tex]y = 1 \times |x - 1| + 3[/tex]
So, we have:
[tex]y =|x - 1| + 3[/tex]
Represent as a function
[tex]g(x) =|x - 1| + 3[/tex]
Hence, the equation that represents the function on a coordinate plane is [tex]g(x) =|x - 1| + 3[/tex]

Mr. Grouper has budgeted $2000 for a graduation party for his son. The cost to rent the venue is $150 and each guests receives a $3.50 gift. How many people can Mr. Grouper invite to his sons graduation party?
Answers
Answer:
Mr. Grouper can invite 528 people to his sons graduation party.
Step-by-step explanation:
x= number of people
3.50x +150 =2000
-150
3.50x = 1850
1850/ 3.50
528.571428571 = 528
Mr. Grouper can invite around a total of 528 people to attend for the graduation party of his son.
What is Equation?Equation is a statement including expressions on two sides related by an '=' sign. This may or may not include two or more variables and can be solved using various methods.
Total budget for the graduation party = $2000
Cost to rent the venue = $150
Cost of gift for each guest = $3.50
Let n be the number of guests invited for the party.
Then 3.50n will be the total cost for the guests.
Then we have the linear equation,
150 + 3.50 n = 2000
Solving this will get the number of guests, n.
3.50n = 2000 - 150
3.50n = 1850
n = 1850 / 3.50
n = 528.57 ≈ 528
Hence Mr. Grouper can invite almost 528 people to his son's graduation party.

Answers
Answer:

Step-by-step explanation:
Mathematically;
Average rate of change on an interval [a,b] is;
f(b) - f(a)/b-a
f(0) = -3/5
f(3) = -3/14
a = 0
b = 3
Making the substitution, we have
-3/14-(-3/5)/3-0
= 3/5-3/14/3
= (42-15)/70/3
= 27/70/3
