Answer:
The equation representing the total distance would be A. 105x + 90.
The time the truck has travelled would be 8 hours while the time traveled by the train would be 6 hours.
Step-by-step explanation:
Firstly, let's set the time travelled by the train to be x hours.
According to the question, the equation would be 45(x + 2) = 60x, because the truck has travelled 2 more hours than the train.
Hence:
[tex]45(x + 2) = 60x[/tex]
[tex]45x + 90 = 60x[/tex]
[tex]90 = 60x - 45x[/tex]
[tex]15x = 90[/tex]
[tex]x = 6[/tex]
Therefore, the truck has travelled a total of (6 + 2) hours = 8 hours, and the train has travelled for 6 hours.
Also, the equation can be found by adding both equations up:
[tex]45(x + 2) + 60x[/tex]
[tex]= 45x + 90 + 60x[/tex]
[tex]= 105x + 90[/tex]

Learning Task 1: Graph each pair of linear equations in one coordinate plane.
1. y = 2x + 2 and 2y = 4x + 4
2. Y= x-5 and y = -x + 3

Answer:
We kindly invite you to see the explanation and images attached below.
Step-by-step explanation:
From Geometry we know that every line can be formed by knowing two two distinct points in a plane. Our stategy consist in using two distinct points for each linear equation in order to create our plot.
1) [tex]y = 2\cdot x + 2[/tex], [tex]A(x,y) = (0, 2)[/tex] and [tex]B(x,y) = (1,4)[/tex].
The line [tex]2\cdot y = 4\cdot x + 4[/tex] is a multiple of [tex]y = 2\cdot x + 2[/tex]. We present the graph below.
2) [tex]y = x-5[/tex], [tex]A(x,y) = (0,-5)[/tex] and [tex]B(x,y) =(1,-4)[/tex].
[tex]y = -x+3[/tex], [tex]C(x,y) = (0, 3)[/tex] and [tex]D(x,y) = (1,2)[/tex].
Finally, we proceed to plot each line and present the results below.
3) [tex]y = 2\cdot x-3[/tex], [tex]A(x,y) = (0,-3)[/tex] and [tex]B(x,y) = (1, -1)[/tex].
[tex]y = 2\cdot x + 4[/tex], [tex]C(x,y) = (0,4)[/tex] and [tex]D(x,y) = (1,6)[/tex].
Finally, we proceed to plot each line and present the results below.

Range is the set of y-values that are outputted by function f(x)Step-by-step explanation:
From the graph we see that our y-values span from -4 to 4. When y = -4, it is a open dot, meaning it is exclusive. When y = 4, it is a closed dot, meaning it is inclusive. Therefore, our range is:
(-4, 4] or -4 < y ≤ 4

The school that Anthony goes to is selling tickets for a choir concert. On the first day of ticket sales his school sold 3 senior citizen tickets and 1 child ticket for a total of $38. The school took in $52 on the second day by selling 3 senior citizen tickets and 2 child tickets. What is the price of a senior citizen ticket?
Answer:
A senior citizen costs $8
Step-by-step explanation:
Represent senior citizens with S and children with C.
The first day is represented as:
[tex]3S + C = 38[/tex]
The second day is represented as:
[tex]3S + 2C = 52[/tex]
Required
Solve for C and S
Make C the subject in the first equation
[tex]C = 38 - 3S[/tex]
Substitute 38 - 3S for C in the second equation
[tex]3S + 2(38 - 3S) = 52[/tex]
[tex]3S + 76 - 6S = 52[/tex]
Collect Like Terms
[tex]3S - 6S = 52 - 76[/tex]
[tex]- 3S = -24[/tex]
Divide through by -3
[tex]S = 8[/tex]
Recall that: [tex]C = 38 - 3S[/tex]
[tex]C = 38 - 3 * 8[/tex]
[tex]C = 38 - 24[/tex]
[tex]C = 14[/tex]
Hence, a senior citizen costs $8

Lillian has a defined benefit plan that promises an annual retirement benefit based on 2% of her final 3-year average annual salary for each year of service. At retirement, Lillian has 15 years of service and had an average salary of $80,000 over the last 3 years. What is the amount of her annual benefit?
Answer:
the amount of her annual benefit is $24,000
Step-by-step explanation:
The computation of the amount of her annual benefit is as follows:
= Given percentage × average salary × number of years of service
= 2% × $80,000 × 15 years
= $24,000
Hence, the amount of her annual benefit is $24,000
We simply applied the above formula so that the correct value could come
And, the same is to be considered
Based on the information given the amount of her annual benefit is $24,000.
Using this formula
Annual benefit= Annual retirement benefit percentage × Average salary × Years of service
Where:
Annual retirement benefit percentage=2% or 0.02
Average salary=$80,000
Years of service=15 years
Let plug in the formula
Annual benefit= 0.02 × $80,000 × 15 years
Annual benefit=$24,000
Inconclusion the amount of her annual benefit is $24,000.

How do I solve for x
Answer:
1. x = 3
2. x = 8
3. x = 5
4. x = 8
Step-by-step explanation:
1. 18 = 6x
divide both sides by 6
x = 3
2. x + 7= 15
subtract 7 from both sides
x = 8
3. 2x - 2 = 8
add 2 to both sides
2x = 10
divide 10 by 2
x = 5
4. -1 + x = 7
add 1 to both sides
x = 8

If t= 9m,what is the area of the triangle
Help
Answer: the answer
we use the formula 1/2 .b .h
Step-by-step explanation:
the answer is 1,134, we substitute the t to 9 for each number, for example 4(9) 7(9)
4(9)= 36
7(9)=63
now we find the half of our bottom number which is 4=36
1/2 36= 18
so now we have 18x63=1,134
so our answer is 1,134
The area of the triangle is 1134 m²
What is the area of Triangle?
A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
Given data ,
The value of t = 9 m
Let the base of the triangle be b = 4t
= 4 x 9
= 36 m
Let the height of the triangle be h = 7t
= 7 x 9
= 63 m
Now , the area of the triangle = ( 1/2 ) x Length x Base
So , substituting the values , we get
Area of the Triangle = ( 1/2 ) x 36 x 63
= 18 x 63 m²
= 1134 m²
Therefore , the area is 1134 m²
Hence , the area of the triangle is 1134 m²
