If you compare the functions:
[tex]\begin{gathered} f(x)=4x+9 \\ g(x)=4x+7 \end{gathered}[/tex]Considering f(x) as the parent function, let's analyze each option:
1) Translation 2 units right.
To translate a function 2 units to the right, you have to subtract 2 to the x-term:
[tex]\begin{gathered} h(x)=f(x-2)=4(x-2)+9 \\ h(x)=4\cdot x-4\cdot2+9 \\ h(x)=4x-8+9 \\ h(x)=4x+1 \end{gathered}[/tex]As you can see the resulting function, h(x), is not equal to g(x), which means that the transformation applied was not a shift 2 units to the right.
2) Translation 2 units to the left
To translate the function two units to the left, you have to add 2 to the x-term:
[tex]\begin{gathered} i(x)=f(x+2)=4(x+2)+9 \\ i(x)=4\cdot x+4\cdot2+9 \\ i(x)=4x+8+9 \\ i(x)=4x+17 \end{gathered}[/tex]The resulting function, i(x), is not equal to g(x), which means that the transformation applied was not a shift of 2 units to the left.
3) Translation 2 units up
To translate a function 2 units up, you have to add 2 to the function, that is:
[tex]\begin{gathered} j(x)=f(x)+2=(4x+9)+2 \\ j(x)=4x+9+2 \\ j(x)=4x+11 \end{gathered}[/tex]The function j(x) is different from the function g(x), so the transformation applied was not a shift 2 units up.
4) Translation 2 units down
To shift a function two units down, you have to subtract 2 from the function:
[tex]\begin{gathered} k(x)=f(x)-2 \\ k(x)=(4x+9)-2 \\ k(x)=4x+9-2 \\ k(x)=4x+7 \end{gathered}[/tex]The functions k(x) and g(x) are equal, which means that to determine the function g(x) the function f(x) was translated 2 units down.

Find the midpoint between coordinates (-8,6)
and (-10,4)
Answer:
(-9, 5)
Step-by-step explanation:
A midpoint is the point, or center at the middle of two given points.
The midpoint formula:
[tex](Xm, Ym)= (\frac{x1 + x2}{2}), (\frac{y1 + y2}{2})[/tex]
X1, Y1 is an endpoint
X2, Y2 is an endpoint.
Explanation:
X1, Y1= (-8, 6)
X2, Y2= (-10, 4)
[tex]Xm, Ym= \frac{(-8)+(-10)}{2}, \frac{(6+(4)}{2}[/tex]
[tex]Xm, Ym= \frac{-18}{2}. \frac{10}{2} \\\\Xm, Ym= (-9, 5)[/tex]

Josie is participating in a charity bike ride. This table and graph represent her performance during the ride where x is the number of hours Josie rides and y is her distance from the finish line. Match the quantity to the correct feature and interpretation.
Hours (x) 0 2 4 6 Kilometers away from finish line (y) 75 50 25 0
(ur answer) The x-intercept. The amount of time, in hours, that has passed when Josie completes the race.
(ur answer) The y-intercept. Josie's distance, in kilometers, from the finish line when she begins the ride.
(ur answer) The slope: the absolute value of the slope represents the speed Josie is riding in kilometers per hour.
ANSWERS TO PUT IN:
1. -25/2
2. 6
3. 75
The value of the x-intercept is 6, the y-intercept is 75, and the value of the slope is -25/2.
What is the slope?The ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).
[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]
The x-intercept from the graph(where y = 0)
The x-intercept = 6
The y-intercept from the graph(where x = 0)
The y-intercept = 75
The slope can be found using two points: (0, 75) and (2, 50)
[tex]\rm m =\dfrac{50-75}{2-0}[/tex]
m = -25/2
Thus, the value of the x-intercept is 6, the y-intercept is 75, and the value of the slope is -25/2.

Given f(x) and g(x) = f(x) + k, from the graph, we can determine the value of k as 4 units.
In the question,
Given f(x) and g(x) = f(x) + k
From the graph, we can say that there is a shift of 4 units up between f(x) and g(x).
The given lines are parallel lines, so their slopes will be the equal but intercepts will be different for both the lines.
The y-intercept of f(x) = -3 and that of g(x) = 1
Hence, the difference between the intercepts when calculated is (1 -(-3)) = 4.
Therefore, g(x) = f(x) + 4
So, the value of k is 4.

Three sisters share some money. the oldest gets 5/11 of the share. The older gets 7/12 of the remainder. what fraction of the money does the old girl gets?
The fraction of the money the old girl gets is 7x/22 and the oldest gets 5x/11.
How much does an older girl get?Given,
Oldest gets 5/11 of the share.
The older gets 7/12 of the remainder.
Solution:
Let x be the total amount.
Oldest share = 5/11*x
= 5x/11
Older share =( x - 5/11*x)*7/12
= (11x-5x/11)*7/12
= 6x/11*7/12

Answer:
This relation is NOT a function
Step-by-step explanation:
As you see in the attached image, the x value of 1 has 2 different points assigned to it. This relation would fail the vertical line test, therefore it is not a function.
Key words:
Relation: Any graph
Function: A relation that has 1 y value for every x value
Vertical line test: An imaginary line drawn on a relation/function to test if it is a function. (in some cases, like this relation, you will see right away from the placement of the points that it is not a function)

The Equation P= 2.5m + 35 represents the price P (in dollars) of a bracelet, where m is the cost of the materials (in dollars). The price of a bracelet is $115. What is the cost of the materials?
Answer:
The cost of materials is $32.
Step-by-step explanation:
You can solve this in a simple manner:
115 = 2.5m + 35
115-35 = 2.5m
80 = 2.5m
m = 32
You can check your answer by putting 32 back into the equation(P=2.5m+35) and you should get 115(which is price of bracelet)

Solve the simultaneous equations.
x^2+y^2=13
y=x+1
Solving the simultaneous equation gives x as 2 and y as 3
How to solve the simultaneous equationFrom the information given, we have the equations as;
x² + y² = 13 equation (1)y = x + 1 equation (2)Now, substitute the value of y as x + 1 in equation (2) into the equation (1)
We have;
x² + (x + 1)² = 13
expand the bracket
x² + (x + 1)(x+1) = 13
x² + x² + x + x +1 = 13
collect like terms
2x² + 2x + 1 - 13 = 0
2x² + 2x - 12 = 0
Factorize the equation
2x² + 6x - 4x - 12 = 0
Factor the common terms
2x(x + 3) - 4(x + 3) = 0
2x - 4 = 0
x = 2
x = -3
Substitute x as 2 into equation (2)
y = x + 1
y = 2 + 1
y = 3
Hence, the values are 2 and 3

The slope is -0.1 starting at 3.9, the GPA will decrease by 0.1 for each text sent in class.
Here we have to find the slope.
The equation given is:
y = 3.9 - 0.1x
As we know that the equation of a line is:
y = mx + c
Therefore we get that the slope is m = -0.1
Starting at 3.9 the GPA will decrease by 0.1 for every text sent in class ( for y = mx + b, a is the slope which is the coefficient of x)
Because the slope is less than 0, it is decreasing.
Therefore the slope is -0.1 and there is a decrease in GPA of 0.1.

Given the function 15z +80=470, determine the maximum number of people who can be at the party.
Answer:

Step-by-step explanation:
15z +80 = 478
15z = total cost of the people
80 = cost of room

2x-15 = 61°

Step-by-step explanation:
2×-15+3x +5= 180
180+10= 190
190 ÷5x
×=38
Answer:
a) x = 38
b) 61° and 119°
Step-by-step explanation:
Same-side Exterior Angles Theorem
When two parallel lines are intersected by a transversal, the angles that are exterior to the parallel lines and on the same side of the transversal line are supplementary (sum to 180°).
Part (a)Using the Same-side Exterior Angles Theorem, equate the sum of the two angles to 180° and solve for x:
⇒ (2x - 15)° + (3x + 5)° = 180°
⇒ 2x - 15 + 3x + 5 = 180
⇒ 5x - 10 = 180
⇒ 5x = 190
⇒ x = 38
Part (b)Substitute the found value of x from part (a) into the expressions for each angle:
⇒ (2x - 15)°
⇒ (2(38) - 15)°
⇒ (76 - 15)°
⇒ 61°
⇒ (3x + 5)°
⇒ (3(38) + 5)°
⇒ (114 + 5)°
⇒ 119°
Therefore, the two angles are 61° and 119°.
