Answer:
k = 10
Step-by-step explanation:
180° - 115° = 65°
(4k + 5) + (6k + 10) + 65 = 180
4k + 5 + 6k + 10 + 65 = 180
10k + 80 = 180
10k = 100
k = 10

Answers
Answer:
-294
Step-by-step explanation:
f(3) = 6(3) + 3
f(3) = 18 + 3
f(3) = 21
g(-4) = 3(-4) - 2
g(-4) = -12 - 2
g(-4) = -14
f(3) * g(-4) = 21 * -14 = -294

Fill in the known values!
2(2)* (5+ W) = 90
Solve for W!
4*(5+W)=90

Find the midpoint of the segment with the following endpoints.
(8,9) and (4,3)
Answers
Answer:
The midpoint of the segment is (6,6).
Step-by-step explanation:
To solve this problem, we are going to use the midpoint formula, which is shown below:
( (x1+x2)/2, (y1+y2)/2 )
If we plug in the values that we are given in the question, we get:
( (8+4)/2, (9+3)/2)
We should add together the two numbers in the numerator of each fraction to begin the simplification process:
(12/2, 12/2)
Now, we can perform the division to find our final answer.
(6,6)
Therefore, the correct answer is (6,6).

Lin has a drawing with an area of 20 in²
If she increases all the sides by a scale factor of 4, what will the new area be?
Answers
Answer:
320 in²
Step-by-step explanation:
Given that Lin has a drawing that has an area of 20 in², since Lin used a scale factor of 4 to increase all sides, therefore the new area would be increased by the following:
Square of scale factor of the side = scale factor of area
4² = scale factor of area
16 = scale factor of area
Multiply the original area by 16
20 × 16 = 320 in²

Kayla thinks that the slope of a vertical line is undefined, while Joshua
argues that the slope of a vertical line is zero. Who is correct?
a. Kayla b. Joshua
Answers
Answer:
Kayla
Step-by-step explanation:
Vertical lines are always undefined because if your answer has to be divided by zero, the answer is an undefined operation.
Horizontal lines always have the slope of zero!
The slope of a vertical line is undefined.
Kayal is correct.
The rate of change in the table is -6.
The slope of the graph is 3/2.
What is a slope?The slope of a is the change in the y coordinate with respect to the change in the x coordinate.
We have,
A vertical line means there is no change in the x-coordinate.
i.e slope = change in y-coordinates / change in x-coordinate
slope = change in y-coordinate / 0
slope = undefined
The slope of a vertical line is undefined.
Now,
From the given table we see that there is a change of 1 for the x-values and a change of -6 in the y-values so,
Rate of change in the table:
= change in y values/change in the x values
= -6 / 1
= -6
Now,
Take any two points on the graph such as:
(a, b) = (4, 6) and (c, d) = (-4, -6)
The slope of the graph:
= (d - b) / (c - a)
= -6 - 6 / -4 - 4
= -12 / -8
= 3 / 2
Thus,
The slope of a vertical line is undefined.
Kayal is correct.
The rate of change in the table is -6.
The slope of the graph is 3/2.

Can someone help me with this??
Answers
Answer:
Step-by-step explanation:
Let the number of weeks = x
4*2.54 + 4x = growth for A
10*2.54 + 1*x= growth for B
So they will be the same when the 2 left sides are equated.
10.16 + 4x = 25.5 + x Subtract 10.16 from both sides
4x =25.5-10.16 + x Combine
4x = 15.34 + x Subtract x from both sides.
4x-x = 15.34
3x = 15.34 Divide by 3
x = 15.34/3
x = 5.11
So the answer is just a little over 5 weeks.
Karen used a birthday check her mother gave her to start a savings account. She plans to save $25 per
month as well. After 8 months, Karen has $250. Write and solve a linear equation to find the original check
amount from Karen's mother.
Answers
Answer:
Explanation:
Lets just say the amount her mom gave her is c
and the months is a
the equation would be
c + 25a = 250
we can plug in 8 for a, cause we know its been 8 months,
c + 25(8)= 250
then do the parentheses
c + 200 = 250
subtract the 200 to isolate the variable c
c = 50
then you get c = 50,
Karen's mom gave her a check for $50.
(why karen btw. i would never give $50 to a karen)
The linear equation to calculate the amount from Karen's mother is
A + 25x = 250
where A is the amount and x is the number of months
The amount from Karen's mother is $ 50
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the amount given to Karen by her mother be = A
Let the total number of months be = x
The value of x is = 8 months
The total amount Karen has after 8 months = $ 250
The amount Karen saves per month = $ 25
Now , the equation will be
Total amount Karen has after 8 months = amount given to Karen by her mother + ( amount Karen saves per month x total number of months )
Substituting the values in the equation , we get
250 = A + 25x
On simplifying the equation , we get
A + 25x = 250
when x = 8
A + 25 ( 8 ) = 250
A + 200 = 250
Subtracting 200 on both sides of the equation , we get
A = $ 50
Therefore , the value of A is $ 50
Hence , The linear equation to calculate the amount from Karen's mother is A + 25x = 250
where A is the amount and x is the number of months
The amount from Karen's mother is $ 50
