Answer: A
Explanation:
Step 1: Use the linear graph to create an equation using slope-intercept form. The y-intercept is (0,-6) because that's where the line passes the y-axis. The slope is 1/2 and that's pretty self-explanatory if you know how to find slope. The equation would be y=1/2x-6.
Step 2: Because we are looking for a line perpendicular to the linear graph, the y-intercept and slope needs to be different. If they're perpendicular, they need to intersect, so the slope needs to be the reciprocal of the original slope, 1/2. The reciprocal is -2. Your equation would be y=-2x+b, and since we don't know the y-intercept, we would leave it as b.
Step 3: Plug in the given ordered pair, (-3,-2), to get -2=-2(-3)+b. You would result with -2=6+b. Subtract 6 to both sides and you would get b=-8.

Step-by-step explanation:
You and your friend walk to school together every day. You meet at the halfway point between your houses first and then walk to school. Each unit in the coordinate plane corresponds to 50 yards. A) What are the coordinates of the midpoint of the line segment joining the two houses? B) What is the distance that the two of you walk together?
Please show the steps
Answer:
no se
Step-by-step explanation:
The coordinate of the midpoint joining the two houses, since each unit on the coordinate is 50 units is (150, 250) and the distance walked to school is 254.95 yards
From the graph given :
The x - coordinate of the midpoint is 3 units from the origin = (3 × 50) = 150 yards
The y-coordinate of the midpoint is 5 units from the origin = (5 × 50) = 250 yards
Hence, the coordinate of the midpoint is (150, 250)
The distance walked to school :
Distance = √(y2 - y1)² + (x2 - x1)²
Distance = √(400 - 150)² + (300 - 250)²
Distance = √250² + 50²
Distance = 254.95 yards
Therefore, the distance the boys walk to school is 254.95 yards.

2X+20 and X+60 I have to solve for X
Answer:
x = 40
Step-by-step explanation:
I don't understand, but I think you mean 2x + 20 = x + 60
So that's what I'm going to solve for if that's wrong tell me what you mean.
2x + 20 = x + 60 (subtract 20 on both sides)
2x = x + 40 (subtract x on both sides)
x = 40

Answer:
a) 6.1 feet
b) 12.6 feet
Step-by-step explanation:
Using trigonometric ratios we know that:
[tex]sin = \frac{opp}{hyp}\\cos = \frac{adj}{hyp}\\tan = \frac {opp}{adj}[/tex]
AKA SohCahToa.
To find the height, we will use sine.
[tex]sin(26^o)= \frac{x}{14}\\14*sin(26^o)=\frac{x}{14}*14\\14sin(26^o)=x\\x=6.14[/tex]
To find the length we will use cosine.
[tex]cos(26^o) = \frac{x}{14}\\14*cos(26^o)=\frac{x}{14}*14\\14cos(26^o)=x\\x=12.6[/tex]

Find the value of n that makes DEF-XYZ when
DE = 4, EF = 5, XY = 4(n + 1). YZ = 7n - 1, and
Answer: n=3
Step-by-step explanation:
Understand that you need to set up a proportion before you can try to solve the question through guessing. In this case, YZ would be proportional to XY as EF is proportional to DE. You would write this as: EF/DE=YZ/XY.
Now you want to write an equation. In order to do this remember to multiply by your proportion. Here’s my equation:
5/4(4n+4)=7n-1. Now distribute:
5n+5=7n-1. Now simplify:
6=2n. Now simplify again:
n=3
Hope this helps you with your big ideas math hw!
The value of is n=3
Important information:DEF-XYZ whenDE = 4, EF = 5, XY = 4(n + 1). YZ = 7n - 1.The calculation is as follows:5/4(4n+4)=7n-1.

The average depth of the Artic Ocean is 3.953 x 10^5 feet while the average depth of the Atlantic Ocean is 1.2851 x 10^4 feet. Approximately how many times more deep is the Atlantic Ocean that the Artic Ocean?
Answer:
Hence the artic depth is approximately 31 times deeper than atlantic
Step-by-step explanation:
Given the following;
Average depth of the Artic Ocean = 3.953 x 10^5 feet
Average depth of the Atlantic Ocean = 1.2851 x 10^4 feet.
Taking the ratio of both depth;
Ratio = Depth of Artic/Depth of Atlantic
Ratio = 3.953 x 10^5/1.2851 x 10^4
Ratio = 3.076 * 10^1
Ratio = 30.76
Depth of artic/depth of atlantic = 30.76
Depth of artic = 30.76 * depth of atlantic
Hence the artic depth is approximately 31 times deeper than atlantic

A small moving box has a volume of 2304 inches cubed and length of 16 inches. The box's width and height are the same. Write the equation that models the volume of the box. Let x represent the width. Solve the equation. Find the width and height of the box.
Answer:
V = 16x²
Width = 12in
Height = 12in
Step-by-step explanation:
Volume of the box is expressed as;
V = Length *Width * height
Given
Length = 16in
Width = x
Height = x
The volume of the box will be expressed as;
V = 16 * x * x
V = 16x² (This gives the required equation)
To get x:
We are given
V = 2304in³
Substitute;
2304 = 16x²
x² = 2304/16
x² = 144
x= √144
x = 12
Hence the width and the height are both 12inches since they are the same.
