Answer:
Think about it this way:
triangle KDI is supplementary to EHK. SO if we find the angles of KDI we can do the same for EHK. Additionally, the m<H in the triangle HKF is 90 degrees and since it is supplementary to EHK then the measure of h in EHK is also 90 degrees. So m<h is 90. All three angles will equal to 180 since the interior angles of any triangle equal 180°
Now, lets find the measures of KDI so we can solve for the measure of K in the triangle EHK
D in KDI is 19 degrees and the square on I in KDI indicates its a 90 degree angle. Those add up to 109 degreess meaning measure of k must equal 71 degrees (180=109=71) since the interior angles of any triangle equal 180. Therefor in the triangle EHK, h is 90, and k is 71 degrees by vertical angles theorem. 90 and 71 add up to 161 degrees meaning angle E is going to be equal to 19 (180-161=19). this, therefore means 17x-7=19
solve:
17x-7=19
17x=26
x=26/17
x=1 9/17
You can write it as a decimal, improper fraction or mixed number.

A credit card company uses your average daily balance to compute your finance charge. You charge $100 on May 2 and $200 on May 20. What is your average daily balance?
Answer:
$5.56Step-by-step explanation:
On may 2, charge = $100
On may 20, charge = $200
To get the average daily balance, we will use the concept of calculating slope;
let d be day of the month and c be the amount charged
when d1 = 2, c1 = 100
when d2 = 20, c2 = 200
average daily balance = c2-c1/d2-d1
average daily balance = 200-100/20-2
average daily balance = 100/18
average daily balance ≈ 5.56
Hence your average daily balance is approximately $5.56

Sarah pained her birdhouse this weekend. She painted 1/5 of her birdhouse with 2/3 cans of paint. How many cans of paint will she need to complete her birdhouse
Answer:
8/3 or 2.666666..........
Step-by-step explanation:
20% = 2/3
100 / 20 = 5
so it will take 5 * 2/3 or (10/3) to paint the whole house
but use had used 2/5
so the Answer is (10/3) - (2/5) = 8/3
work out the inverse function
y=x-2
Answer:
x + 2
Step-by-step explanation:
Replace the x with y.
Making is x = y -2
Solve for x=y-2
and you get x+2
Answer:
x+2
Step-by-step explanation:
When doing inverse functions, you switch the x and y.
x = y-2
Then you solve for y (add the 2 to the other side to get "y" by itself)
y = x+2

Find the slope and y-intercept. Also, determine if it is Proportional or Non Proportional
Answer:
Step-by-step explanation:
Slope of a line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
From the table attached,
Two points lying on the graph are (1, 12) and (2, 24).
Slope of the line will be,
m = [tex]\frac{24-12}{2-1}[/tex]
Slope = 12
Since equation of a line passing through a point (x', y') and slope 'm' is,
y - y' = m(x - x')
Therefore, equation of the line passing through (1, 12) and slope 12 will be,
y - 12 = 12(x - 1)
y = 12x - 12 + 12
y = 12x
By comparing this equation with the equation,
y = mx + b
where 'b' = y-intercept = 0
Since, y-intercept is zero, table will represent the proportional relation between x and y.
Proportional or non proportional → Proportional

Answer:
y = (-7/3)x +3
Step-by-step explanation:
The line has a negative slope (eliminating choices B and C) that is steeper than a line with a slope of -1, The only answer choice with a negative slope less than -1 is choice D.
__
The slope is the coefficient of x. It is "rise"/"run". Here, the line goes through grid points (0, 3) and (3, -4), so drops 7 units (rise=-7) for each 3 units to the right (run=3). Then the slope is rise/run = -7/3.
The line crosses the y-axis at y=3, so the slope-intercept equation is ...
y = mx + b . . . . . . . . slope = m; y-intercept = b
y = (-7/3)x +3

Xavier can paint the average house in 4 hours, while Mohamad can do it in 12 hours. Find the number of hours, $$, that it would take to paint a house if they both worked together.
Answer:
3 hours
Step-by-step explanation:
Xavier can paint the average house in 4 hours
This means that in 1 hour, Xavier paints 1/4 of the house
Mohamad can do it in 12 hours
That means in 1 hour, Mohamad paints 1/12 of the house
Hence,
Together the amount of the house they can paint in 1 hour is
1/4 + 1/12
The Least common denominator is 12
(3 × 1 + 1 × 1)/1#
= 3 + 1/12
= 4/12
= 1/3
Together they can paint 1/3 of the house
The number of hours, that it would take to paint a house if they both worked together is
= 1/3 = 1
Cross Multiply
= 3 × 1
= 3 hours

Sheila has 10 1/2 pounds of potato salad. She wants to divide the potato salad into containers, each of which holds 2 1/4 pounds. How many containers does she need? Complete the explanation.
Answer: 5 containers
Step-by-step explanation:
Step 1
Given that
Total amount of potato salad = 10 1/2
amount of salad in each container = 2 1/4
Total number of containers = ?
Step 2
Divide the total amount of potato salad by the amount of salad each container can hold
Total number of containers=10 1/2 / 2 1/4 = 21/2 x 4/9= 84/18 = 4 3/5
which can also be written as 10.5 / 2.25= 4.6
Sheila will need 5 containers because 4 will be filled and additional 1 will be partially filled.

Write the standard form of the equation of a line with a slope of 3 passing through the point (-1, -5).
Select one:
a. -x + 3y + 14 = 0
b. x - 3y - 14 = 0
c. 3x - y - 2 = 0
d. -3x + y + 2 = 0
Step 1: We start by writing the equation of the line in slope-intercept form by solving for b.
[tex]-5 = 3(-1) + b\\\\-5 = -3 + b\\\\-2 = b\\[/tex]
Step 2: Now we set up the equation of the line in slope-intercept form.
[tex]y = 3x - 2[/tex]
Step 3: We can now convert the above equation from slope-intercept form to standard form.
[tex]y = 3x - 2\\\\-3x + y = -2\\\\-3x + y + 2 = 0[/tex]
The equation of the line in standard form is: D: -3x + y + 2 = 0.

Instructions: Write and solve an equation to find the measure or angle x.
Answer:
x = 30
Step-by-step explanation:
Okay the triangle should add up to 180.
The square represents a right angle = 90°
So just do this
60° + 90° + x = 180 (collect like terms)
150° + x = 180 (subtract 150 on both sides)
x = 30
Hope this helps ya!
Answer:
x = 30
Step-by-step explanation:
the trinagle has an angle of 180.
and the trainage has a 90° next to the 60
So
60° + 90° + x = 180 (there are term)
150° + x = 180
subtract 150 on both sides
150 - 150 180-150 = x = 30

X+y=8
Y=3x
Solve with substitution
Correct answer gets Brainliest!!
Answer:
x=2, y = 6
Step-by-step explanation:
We see that y = 3x so we can substitute the y in x + y = 8.
x + 3x = 8.
Combine like numbers:
4x = 8.
Divide both sides by 4.
x = 2
Now plug in x to find y
2 + y = 8
Subtract 2 from both sides.
y = 6
