5x + 2 = 3(x + 14)
Step 2: Solve for x
Distribute 3: 5x + 2 = 3x + 42Subtract 3x on both sides: 2x + 2 = 42Subtract 2 on both sides: 2x = 40Divide 2 on both sides: x = 20Step 3: Find m∠KNL
Define: m∠KNL = 3(x + 14)°Substitute: m∠KNL = 3(20 + 14)°Add: m∠KNL = 3(34)°Multiply: m∠KNL = 102°Related Questions

Step-by-step explanation:
Grant finds the difference of 360 and 127 as shown. What is Grant's
mistake?
Grant should have subtracted the ones first and
the hundreds last.
Grant did not regroup the 2 hundreds when he
subtracted 7.
360
- 100
260
20
240
7
243
Grant should have subtracted 120 instead of 20.
Grant did not regroup the 4 tens when he
subtracted 7
Done
Hey
Answers
Answer:
D. Grant did not regroup the 4 tens when he subtracted 7.
Step-by-step explanation:
In the process of subtraction, regrouping is important so that each digit in the given numbers are placed appropriately before the required arithmetic operation is performed.
The correct step to Grant's solution are:
360 - 100 = 260
260 - 20 = 240
240 - 7 = 233
Grant's final answer ought to have been 233.
Going through his solution, he made a mistake while subtracting 7 from 240. He failed to regroup the 4 tens when he subtracted 7 from 240. Thus the essence of his wrong answer.

In the diagram below, what is the equation that represents the relationship between the number of triangles and the perimeter of the figure they form? Use this table to help you create an equation.
Answers
Answer:
The perimeter of the figure as a function of the number of triangles is [tex]y = 6 + 4\cdot x[/tex].
Step-by-step explanation:
According to the diagram, we get the following facts:
i) For one triangle ([tex]x=1[/tex]), the total perimeter is ([tex]y=2\cdot 3 + 1\cdot 4 = 10[/tex]).
ii) For two triangles ([tex]x = 2[/tex]), the total perimeter is ([tex]y = 2\cdot 3 +2\cdot 4 = 14[/tex])
iii) For three triangles ([tex]x = 3[/tex]), the total perimeter is ([tex]y = 2\cdot 3 +3\cdot 4 = 18[/tex])
iv) For four triangles ([tex]x = 4[/tex]), the total perimeter is ([tex]y = 2\cdot 3 +4\cdot 4 = 22[/tex])
From these information we conclude that the equation that determines the perimeter of the figure as a function of the number of triangles is [tex]y = 6 + 4\cdot x[/tex].

Find f^-1(x) (the inverse)
Answers
9514 1404 393
Answer:
does not exist
Step-by-step explanation:
The notation f^-1(x) usually refers to the inverse function. That is, if we have the functional relation
y = f(x)
Then the inverse function f^-1(x) will give you ...
x = f^-1(y)
__
In order for an inverse function to exist, the original function must pass the "horizontal line test." That is, any horizontal line can intersect the function's graph in, at most, one point.
Here, the function f(x) = 245 is a horizontal line, so the horizontal line test fails. The horizontal line at y=245 will intersect f(x) in an infinite number of points.
So, f(x) = 245 does not have an inverse function. f^-1(x) does not exist.
_____
Alternate interpretation of the question
Sometimes, an exponent is applied to a function name when the intended operation is application of the exponent to the function value. For example, you may see sin²(x) when the intended meaning is sin(x)². The application of an exponent to the function name could be confused with multiple applications of the function: sin²(x) = sin(sin(x)), as the notation is sometimes used for this purpose, too.
If what you intend by f^-1(x) is really f(x)^-1, then you can say ...
f(x)^-1 = 1/245
by 8:00 a.m., the snack bar had made $3,256 in sales. By noon, the snack bar's total sales were $8,821. On average how much money did the snack bar take in each hour between 8:00 a.m. and noon?
Answers
Answer:
$1,391.25
Step-by-step explanation:
Noon would be 12:00 PM which would be 4 hours ahead of 8:00 AM
We subtract $8,821 by $3,256 to get the amount earned between 8:00 AM and 12:00 PM
$8,821 - $3,256
= $5,565
The find the average taken in within those 4 hours we will have to divide the money earned by the hours
$5,565/4
= $1,391.25

X-3y=9 into a slope intercept form
Answers
Answer:
y=1/3x-3
Step-by-step explanation:
Slope intercept form is: y=mx+b
so you need to leave y on one side and the others on the other side:
First, you need to move the x to the other side by subtracting x on both sides:
x-x-3y=-x+9
Simplify:
-3y=-x+9
Now you divide -3 on both sides to eliminate the -3 on -3y:
y=1/3x-3
Hope this helps!
- Slope is m which is the gradient.
- the gradient formula is y=mx+b
-I.e mx represent the gradient and b is y-intercept.
- x-3y=9–> 3y=x-9
Then divide 3 to both side to cancel the 3y=y.
—> y=x/3-3
I hope this helps!
