Write the equation for the line of best fit in the slope-intercept form and use it to predict the number of matches that could be won after 13 months of practice Show your work and include the points used to calculate the slope. (5 points)
Answers
The slope-intercept is y=mx+b where m= the slope and b= the y-intercept. it looks like the y-intercept is about 3.5 or 3 1/2. One way to find M is that you take 2 points, ill do (1,5) and (5,12), and then subtract the x's with the x's and the y's with the y's and you would get (1-5, 5-12) which equals -4,-7. then you put the y's on top of a fraction and the x's on the bottom. so you would get -7/-4 when both numerator and denominator are both negative then they cancel out. making the total M= 7/4 which also equals 1 and 3/4, since you want to know after 13 months, the number of months =x so you can substitute and this is your equation: y= 7/4x+ 3.5 substituting the number of months: y= 7/4(13) + 3.5. 7/4 * 13 = 22.75 then you add the 3.5 which equals 26.25 so.
after 13 months of practice, the number of matches won would be about 26.

A boat travels at constant speed. After 20 minutes the boat had traveled 2.5 miles. How long does it take the boat to reach the bridge which is 15 miles away?
Answers
Answer:120 minutes
Step by step:
you have to divide 20 by 2.5 to find how many minutes it takes to drive 1 mile. lastly, multiply that by 15 miles
20 divided by 2.5
20mins - 2.5 miles
2.5 • 3= 7.5 miles in 1hr
7.5+7.5=15 miles in 2hrs
answer: it takes 120 minutes or 2 hours to reach the bridge

Answer:
x = 55°
Step-by-step explanation:
The angles are complementary. That means that they add to 90.
x + x - 20 = 90 Combine like terms
2x - 20 = 90 Add 20 to both sides
2x - 20 + 20 = 90 + 20
2x = 110 Divide both sides by 2
x = 55
Helping in the name of Jesus.
Answer:
x = 55 degrees; the angles are complementary
Step-by-step explanation:
First of all, the angles are complementary. I say this because complementary angles add up to 90 degrees and the square symbol identifies the angle as being a 90-degree angle.
Next, you add [tex]x-20+x[/tex] and set it equal to 90. With some quick addition and some properties of equality, you get the answer of 55 degrees.

Answers
Answer:
B. 335.5 in.²
Step-by-step explanation:
The pencil decoration can be broken down into a rectangle and a triangle.
The area of the pencil decoration is the sum of the areas of the rectangle and triangle.
The rectangle has length b and width a.
The triangle has base a and height a.
total area = area of rectangle + area of triangle
total area = length × width + base × height / 2
total area = b × a + a × a / 2
From the given information, we see that a = 11 in., and b = 25 in.
total area = b × a + a × a / 2
total area = (25 in.) × (11 in.) + (11 in.) × (11 in.) / 2
total area = 275 in.² + 60.5 in.²
total area = 335.5 in.²
Mary has 400 slices of pizza. She gives 30 to Cambri,96 to Maria,99 to Falli,43 to Sam and 32 to Callin. How many slices does she have left?
Answers
Answer:
The answer to your problem is, 100 slices.
Step-by-step explanation:
First lets add up all the numbers that she gives away
30+96+99+43+32 =
300.
If she gave out 300 slices of pizza then here left over is:
400 - 300 = 100.
Thus the answer to our problem is, 100 slices.
30+96+99+43+32=300
400-300=100

C.0.25 + 4.50
D.0.25 -3.00
I would love an explanation to help me understand how to solve the other problems like this one
Answers
it is A. 0.25x - 6.50
You use distributed property first so the equation will be 3x - 1 - 2.75x - 5.50
Then you combine like terms so 3x - 2.75 will equal 0.25x
The subtraction symbol will stick with 1 making it -1 so the second part will be -1 - 5.50 will equal 6.50
And finally, the expression will be 0.25x - 6.50

How do I graph y = -1 = 2x and y = -4 + 2x?
Answers
Answer:
Slope = Rise/Run
To graph, you first need the y-intercept.
In y = -1 + 2x, the y-intercept is -1. Start in -1 and then go two units up, and 1 unit to the right which will represent the slops, 2.
In y = -4 + 2x, the y-intercept is -4, so you'll start at -4, then go 2 u its up, and 1 to the right which will represent the slope, 2.
To find y-intercept:
y = mx + b | main things: m = slope b = y-intercept
