Answer:
(3x + 7) - (4x -2) = 3x + 7 - 4x + 2 = 9 - x
find the appropriate function
Answer:
y = 0.5sin(4x)
Step-by-step explanation:
y = A sin(B(x + C)) + D
amplitude is A = 0.5
B = 2π/period = 2π / (1/2 π) = 4
phase shift is C (positive is to the left) = 0
vertical shift is D = 0
Which of the following represents the factorization of the trinomial below?

Mikael needs to rent a scooter to get to work. The scooter charges $1.85 to activate it and $0.50 per mile Mikael has a gift card for
$10 and he can not spend more on the scooter
O 10 < 0.502 +1.85
O 10 < 1.85.1 +0.50
O 10 > 1.852 +0.50
O 10 > 0.503 +1.85
Answer:
[tex]10 > 1.85 + 0.5m[/tex]
Step-by-step explanation:
Price of the scooter:
Fixed price of $1.85 to activate plus $0.50 for each mile. This situation can be represented by a linear function, and it is given by:
[tex]P(m) = 1.85 + 0.5m[/tex]
Mikael has a gift card for $10 and he can not spend more on the scooter.
The spendings have to be less than 10. So
[tex]10 > P(m)[/tex]
[tex]10 > 1.85 + 0.5m[/tex]
A system of equations is created by using the line represented by2x+4y=0And the line represented by the data in the table below
What is the X value of the solution to the system if x -1 and y is 8
Answer:
x = 2
Step-by-step explanation:
From the data, we obtain the slope :
-1, 8 ; 3, - 4
Slope = Rise / run
Rise = y2 - y1 = (-4 - 8) = - 12
Run = x2 - x1 = (3 - (-1)) = 4
Slope, m = - 12 / 4 = - 3
Recall:
Equation of line :
y - y1 = m(x - x1)
y - 8 = - 3(x + 1)
y - 8 = - 3x - 3
y = - 3x - 3 + 8
y = - 3x + 5
Substituting y = - 3x + 5 into the equation 2x+4y= 0
2x + 4(-3x + 5) = 0
2x - 12x + 20 = 0
-10x = - 20
x = 2

Factoize those 2 questions using "ac"method must include all steps
Answer:
(2x + 5)(3x - 7), (x + 4)(x - 2)
Step-by-step explanation:
a = 6, b = 1, c = -35
? × ? = ac = 6 × -35 = - (2 × 3 × 7 × 5)
? + ? = b = 1
3 × 5 -(negative sign from above) 2 × 7 = 15 - 14 = 1 = b
[tex]\frac{1}{6}(6x + 15)(6x + (-14))[/tex]
= [tex]\frac{1}{6}(3)(2x + 5)(2)(3x - 7)[/tex]
= [tex](2x + 5)(3x - 7)[/tex]
a = 1, b = 2, c = -8
? × ? = ac = 1 × -8 = -(2 × 2 × 2) = 4 × -2
? + ? = b = 2
4 + (-2) = 2 = b
[tex]\frac{1}{1}(1x + 4)(1x + (-2))[/tex]

The graph of y = 2 is shifted down by 6 units and to the left by 9 units.
What is the equation of the new graph?
Choose 1 answer:
A
y=|x + 9 |+ 6
B
y =|x +9| – 6
C y = |2 - 9|+6
D y = |2 - 9|– 6
Answer:
[tex]y = |x + 9| - 6[/tex]
Step-by-step explanation:
Given
[tex]y = |x|[/tex] --- the correct equation
Shifted down 6 units
Shifted left 9 units
Required
The new equation
When function is shifted down by b units, the new function is:
[tex](x,y) = (x,y-b)[/tex]
In this case:
[tex]b =6[/tex]
So, [tex]y = |x|[/tex] becomes
[tex]y =|x| - 6[/tex]
When function is shifted left by b units, the new function is:
[tex](x,y) = (x+b,y)[/tex]
In this case:
[tex]b =9[/tex]
So: [tex]y =|x| - 6[/tex] becomes
[tex]y = |x + 9| - 6[/tex]

A bridge is built in the shape of a parabolic arch. The bridge has a span of feet and a maximum height of feet. Choose a suitable rectangular coordinate system and find the height of the arch at distances of 10, 30, and 50 feet from the center.
Answer:
Height of the arch at distances of 10, 30, and 50 feet from the center is as follow:
Put x = 10 we get
the value of y = 0.695
Put x = 30
the vale of y = 6.26
Put x = 50
the value of y = 17.37
Step-by-step explanation:
The prabolic arch for bridge has span of 120 feet and height f 25 feet. The rectangular corordinate system is
such as
height = h = 25
Distance = x
(x-h) = -4a(y-k)
x² = -4ay
60 = -4a(-25) and
where the value of a =36
therefor the parabolic arch is
x = -144y
For distance of 10 , 20 and 30 let take the feet from center then we have
put x = 10 we get
10² = -144 y
100 / 144 = y
the value of y = 0.695
Put x = 30
30² = -144y
30/144 = y
the vale of y = 6.26
Put x = 50
50² = -144 y
50/144 = y
the value of y = 17.37

Answer:

Step-by-step explanation:
The function is y = x²-1, x ≤ 1 and x²+4 x > 1
What is a function?A function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Given is graph, we need to find its function.
First you look on the left side of the graph.
You can tell by the shape that it is an x³ function. also the filled in circle means inclusive. so we know that when x (whatever number).
It is impossible to tell for sure with this graph if it is on 1. for the first part. the only answer that has less than or equal to is the last one, D.
So the answer is D. You can look on the right side that it is an open circle.
So we can see the bottom part of D has that as well.
Hence, the function is y = x²-1, x ≤ 1 and x²+4 x > 1
