Step-by-step explanation:
(3,2) is the solution to both equations because if you substitute the the x and y values you get a true statement for example
6(3) + 7(2) =32
18 + 14 = 32
32=32
that is a true statement
you can do the same with system B
8(3) +8(2)=40
24 + 16 = 40
40 =40
which is a true statement

Sakura's house is at an elevation between 113 m and 120 m above sea level. Her friend Ted lives about 15 m below her. Choose the compound inequality that describes the elevation x of Ted's house. Part B Ted lives between _____m and _______m above sea level.
The compound inequality to describe the elevation of Ted's house is 135 > x > 128.
Ted lives between 128m and 135m above sea level.
How to explain the inequality?Now it is given that,
Sakura's house is at an elevation between 113 m and 120 m above sea level.
Let x be the elevation of Sakura's house.
So, 120 > x > 113
Now Ted lives about 15 m below her
Ted's house elevation = x - 15
So, the compound inequality to describe the elevation of Ted's house,
120 > x - 15 > 113
Adding 15 to the inequality we get,
120 + 15 > x - 15 + 15 > 113 + 15
Solving we get,
135 > x > 128
This is the required compound inequality.
Thus, the compound inequality to describe the elevation of Ted's house is 135 > x > 128.

2. A rocket is launched from rest, at ground level. The graph of the rocket's velocity with respect to
time looks as follows: y= 0.15x2
How fast is the rocket traveling after 15 seconds?
Insert the graph picture here:
Graph please
Answer:
y = 33.75 m/s.
Step-by-step explanation:
The graph of the rocket's velocity with respect to time looks as follows :
[tex]y=0.15x^2[/tex] ...(1)
Where x is time in seconds
We need to find the velocity of rocket after 15 seconds. Put x = 15 in equation (1).
[tex]y=0.15\times (15)^2\\\\=33.75\ m/s[/tex]
Hence, the speed of the rocket after 15 seconds is 33.75 m/s.

Find the equation of a line parallel to y = 12 that contains the point (3, 2).
Answer:
y = 2
Step-by-step explanation:
Let's first write the equation of y = 12 in slope-intercept form. Slope-intercept form is represented as:
y = mx + b
Where...
m: slope
b: y-intercept (the y-value at where the line intercepts the y-axis)
(x, y): any coordinate on the line
This line has a slope of 0 and a y-intercept of 12, therefore its equation is:
y = 0x + 12.
Parallel lines have the same slope. Therefore the equation of the parallel line can be represented as:
y = 0x + b
We need to find b, or the y-intercept.
Let's substitute the point given to us into the equation.
Solve for the y-intercepty = 0x + b
2 = 0(3) + b
2 = 0 + b
b = 2
Therefore the equation of a line parallel to y = 12 that contains the point (3, 2) is y = 2.
find the slope of the line.

-1/2

Answer:
This

Slope (m) =

-1
= -2
θ =
arctan( ΔY ) + 180°
ΔX
= 116.56505117708°
ΔX = -3 – 0 = -3
ΔY = 0 – -6 = 6
Distance (d) = √ΔX2 + ΔY2 = √45 = 6.7082039324994
Equation of the line:
y = -2x – 6
When x=0, y = -6
When y=0, x = -3

Answer:
D) 41.81 degrees
Step-by-step explanation:
In this problem, we are given a leg length (a=12) and the hypotenuse (c=18).
We need to select which trigonometric identity to use with the acronym SOHCAHTOA:
SOH -> sine=opposite/hypotenuse
CAH -> cosine=adjacent/hypotenuse
TOA -> tangent=opposite/adjacent
Given side a is opposite of angle A and side c is the hypotenuse, we clearly need to use the sine function.
Set up an equation based on the information you have:
sin(A)=12/18
Now take the inverse:
sin^-1(sin(A))=sin^-1(12/18)
A=41.8103149
So the best option is answer D) 41.81 degrees
