b is equal to 1
Step-by-step explanation:
I guessed and it came to be the right answer.
6+7b-7 = 5+b.
6+6b-7 = 5
6+6b=12
6b = 6
B= 1
Answer: 1 so it’s B
what is the slope of (12,22) (-20,19)
Answer:
3/32
Step-by-step explanation:
The slope is found by
m = ( y2-y1)/(x2-x1)
= ( 19-22)/(-20-12)
= -3/-32
= 3/32

The true statements are:
Angle KHE is congruent to angle KFG.Segment EH is congruent to segment FGSegment GH is congruent to segment EF.Given:
Triangle HEF is the image of triangle FGH after a 180-degree rotation about point KAnd Six statementsTo find:
The true statements out of given sic statements.
Solution:
ΔHEF is the image of ΔFGH after a 180°rotation about point K.
This simply implies that ΔFGH is congruent to ΔHEF. As no dilation is done while rotation of the ΔFGH.
In congruent ΔFGH and ΔHEF
HF = HF (common)GH = EFFG = EH∠FGH=∠HEF∠GFH=∠EHFCan also be written as:
⇒ ∠KFG=∠KHE
∠GHF=∠EFHCan also be written as:
⇒ ∠GHK=∠EFK
So, from the given statements the true statements are:

Which list contains all of the factors of the number 48? (1 point)
O1, 2, 3, 4, 6, 8, 12, 16, 24
O2, 3, 4, 6, 8, 12, 16, 24, 48
O1, 2, 3, 4, 6, 8, 12, 16, 24, 48
O1, 2, 3, 4, 6, 8, 9, 12, 16, 24. 48
Answer:
1,2,3,4,6,8,12,24,48.
Step-by-step explanation:
To Find A Factor Of A Number You'll Need To Find Two numbers by which you multiply to get the number you're looking for.SO TO FIND THE FACTOR OF 48 YOU WILL NEED TO FIND TWO NUMBERS THAT CAN MULTIPLY EACH OTHER AND GIVE A PRODUCT OF 48
1×48=48(Any number multiplied by 1 is the number itself and 1 multiplied by 48 is 48 so it makes it a factor)
2×24=48(Here you can clearly see that when 2 is multiplied by 24 the product is 48 so 2 and 24 becomes a factor of 48)
3×16=48(So getting the product 48 by multiplying 3 and 16 3 and 16 becomes a factor of 48)
4×12=48(You can see that when you multiply 4 by 12 the product is 48 so 4 and 12 becomes a factor of 48)
5×?=48(You can't get any number to multiply by 5 to get 48 so the number 5 is not a factor of 48)
6×8=48(With this you can see that when 6 is multiplied by 8 its product is 48 so it becomes a factor of 48)
So The Factors We Got After We Multiplied The Two Numbers Are As Follows;
1 and 48
2 and 24
3 and 16
4 and 12
So the above numbers becomes the factor of 48
So the factors of 48 are: 1,2,3,4,6,8,12,24,48.

• Someone bought 1 pounds of ham for $14.50.
• Someone bought 23 pounds of turkey for $25.25.
• Someone bought i pounds of roast beef for $5.50.
Which meat is the least expensive per pound? Which meat is the most expensive per
pound? Explain how you know.
Answer:
1. Which meat is the least expensive per pound? HAM
2. Which meat is the most expensive per pound? ROAST BEEF
Step-by-step explanation:
I know this because when fractions look smaller people think it's actually a smaller portion but it's actually the bigger number.
HOPE THIS HELPED! <33 .
Answer:The least expensive per pound is ham. and the most expensive is the roast beef.
Step-by-step explanation:
Ham: ($14.50)/(1 3/4 lb) = $14.50/(1.75 lb) = $8.29/lb
Turkey: ($26.25)/(2 1/2 lb) = $26.25/(2.5 lb) = $10.50/lb
Roast beef: ($5.50)/(3/8 lb) = $5.50/(0.375 lb) = $14.67/lb
The least expensive per pound is ham.

Fueleconomy.gov gives the city and highway fuel economy for all makes and models of vehicles back to 1984. The table
gives the city and highway fuel economy (mpg) for a random sample of ten 2021 vehicles
a. Find the equation of the LSRL. Write it below.
b. Find and interpret s.
C. Find and interpret the value of m2
The equation of the Least Square Regression Line which models the data for the city and highway fuel economy and interpreted values of it's parameters are :
Ŷ = 1.264X + 6.084The slope, s = 1.264, per unit increase in miles per gallon of 2021 car models. The intercept Value = 6.084, which is the least value of highway fuel economy a 2021 car model could have.The Least Square Regression Line produces a fitted model of the linear relationship between a given set of data.
Using technology such as Excel or a linear regression calculator, the linear model in the form y = a + bx produced by the data in the table attached is Ŷ = 1.264X + 6.084 ;
Where ; Ŷ = Predicted value of highway fuel economy. X = predictor variable, City Fuel economy. 1.264 = slope value; which is the rate of change in highway fuel economy per unit change in City Fuel economy. 6.084 = Intercept, which is the value of, highway Fuel economy when the city fuel economy is Zero.Therefore, the Least Square Regression Line shows that the there is a positive linear association between City and highway Fuel economy.

The graph of linear function k passes through the points(-7,0) and (1,8). Which statement must be true
Answers
The slope of the graph of k is -4/3.
The graph of k passes through the point (-1,-8).
The zero of k is 7
The x-intercept of the graph of k is -7.
Answer:
✅The x-intercept of the graph of k is -7.
Step-by-sep explanation:
Graph the equation of the line that passes through the points, (-7, 0) and (1, 8) by first generating an equation, and then using the equation of the function to plot the graph.
To find the equation, we need to calculate the slope, m, and y-intercept, b.
✅Using points (-7, 0) and (1, 8), the slope of the line is:
[tex] m = \frac{y_2 - y_1}{x_2 -x_1} = \frac{8 - 0}{1 -(-7)} = \frac{8}{8} = 1 [/tex]
Substitute x = 1, y = 8, m = 1 into [tex] f(x) = mx + b [/tex] to find the y-intercept, b, of the function. (Note: f(x) is same as variable y).
[tex] 8 = 1(1) + b [/tex]
[tex] 8 = 1 + b [/tex]
Subtract 1 from each side
[tex] 8 - 1 = b [/tex]
[tex] 7 = b [/tex]
[tex] b = 7 [/tex]
Substitute m = 1 and b = 7 into [tex] f(x) = mx + b [/tex]
The equation of the function is:
[tex] f(x) = (1)x + 7 [/tex]
[tex] f(x) = x + 7 [/tex]
The graph of the function, k, is shown in the attachment below.
❌Now, we know that the slope of the function, m, is 1. Therefore, option A is not correct.
We also know that the graph of the function, k, does not pass through the points (-1, -8). We can confirm this looking at the graph. ❌The point (-1, -8) is not on the line of the graph. Therefore, option B is not correct.
❌The zero of k, is the value of x for which the function, f(x) or y = 0. From our graph, y = 0, when x = -7. This can also be referred to as the x-intercept. The zero of k is -7, not 7.
Therefore, option C is not correct.
✅The x-intercept is where the line of the function of intercepts the x-axis. From our graph, the line intercepts the x-axis at x = -7.
So, the x-intercept of the graph of k is -7.
Therefore, option D is the only statement that is TRUE.

find the perimeter of the isosceles triangle
Answer:
98 feet
Step-by-step explanation:
divide 48 by 2.
Then do pythag
c2=a2+b2, which is the formula to find c2 = 25
then add all together which is perimeter
Answer: 98 feet
Step-by-step explanation:
First, you need to find the hypotenuse, which is always opposite from the right angle.
Because this isosceles triangle consists of 2 right triangles, they are congruent which means that you can simply just divide 48 by 2 to find the base of one of the triangles, 24.
Next, use a^2 + b^2 = c^2
7^2 + 24^2 = c^2
49 + 576 = c^2
625 = c^2
25 = c
Now, you can find the perimeter.
48 + 25 + 25 = 98 feet
