Answer:
22+4x=90
x=17
Step-by-step explanation:
From the picture, we can see that the two angles form a right angle.
The equation will be 22+4x=90
Then use that equation to solve for x.
4x=68
x=17

Answer:
m∠x = 119°
m∠y = 61°
m∠z = 119°
Step-by-step explanation:
Angle x:
m∠x = 180° - 61° (sum of angles in a straight line)m∠x = 119°Angle y:
m∠y = 61° (Alternate interior angles)
Angle z:
m∠z = 119° (Sum of angles in a line, corresponding angles)

Over which interval is the graph of the parent absolute value function decreasing?.
The graph of the parent absolute value function decreases over (–∞, 0) interval.
What is the parent absolute value function?An absolute value function is a function that contains an algebraic expression within absolute value symbols.
Recall that the absolute value of a number is its distance from 0 on the number line.
The absolute value function is f(x) = |x| is defined as,
[tex]\rm f(x)= x \ if\ x > 0\\\\f(x)= 0 \ if\ x=0\\\\ f(x)=- x \ if\ x < 0\\[/tex]
Observe that the graph is V-shaped.
The vertex of the graph is (0,0).The axis of symmetry (x =0 or y-axis) is the line that divides the graph into two congruent halves.The domain is the set of all real numbers.The range is the set of all real numbers greater than or equal to 0. That is y ≥0.The x-intercept and the y-intercept are both 0.Hence, the graph of the parent absolute value function decreases over (–∞, 0) interval.

Complete the table to determine the cost assigned to ending inventory and cost of goods sold using specific identification
The ending inventory that van be gotten from the table will be $9905 and the cost of goods sold is $5083.
What is ending inventory?It should be noted that the ending inventory simply means the goods that are still available for sale at the end of an accounting period.
From the complete question, the ending inventory will be:
= $3190 + $2295 + $4420
= $9905
Also, the cost of goods sold will be:

Joe will rent a car for the weekend. He can choose one of two plans. The first plan has an initial fee of $51.98 and costs an
additional $0.17 per mile driven. The second plan has an initial fee of $59.98 and costs an additional $0.13 per mile driven. How
many miles would Joe need to drive for the two plans to cost the same?
Answer:
200
Step-by-step explanation:
This problem is about linear equations. We assume Joe drive X miles, and the total cost is $Y, then we can get:
Plan I: Y=51.98+0.17X
Plan II: Y=59.98+0.13X
When both plans cost the same, 51.98+0.17X=59.98+0.13X. We will get X = 200

[tex]\bold{\huge{\blue{\underline{Solution}}}}[/tex]
[tex]\bold{\underline{ Given :- }}[/tex]
Customer 1 bought 2 hamburgers and 4 drinks at a cost of $13.00Customer 2 bought 3 hamburgers and 7 drinks at a cost of $21.00[tex]\bold{\underline{ To \: Find :- }}[/tex]
We have to find the total cost of 8 drinks and 9 hamburgers[tex]\bold{\underline{ Let's \: Begin :- }}[/tex]
Let the cost of hamburgers and drinks be x and y
According to the question,
[tex]\sf{ 2x + 4y = 13.00 ...eq( 1 ) }[/tex]
[tex]\sf{ 3x + 7y = 21.00 ...eq(2) }[/tex]
Solving eq( 1 ) we get :-
[tex]\sf{ 2x + 4y = 13 }[/tex]
[tex]\sf{ 2x = 13 - 4y }[/tex]
[tex]\sf{ x = (13 - 4y)/2 ...eq(3)}[/tex]
Subsituting eq(3) in eq( 2 ) :-
[tex]\sf{ 3( 13 - 4y)/2 + 7y = 21 }[/tex]
[tex]\sf{ 39 - 12y/2 + 7y = 21 }[/tex]
[tex]\sf{ 39 - 12y + 14y = 42}[/tex]
[tex]\sf{ 2y = 42 - 39 }[/tex]
[tex]\sf{ 2y = 3 }[/tex]
[tex]\sf{ y = 3/2 }[/tex]
Subsituting value of y in eq(3) :-
[tex]\sf{ x = 13 - 4(3/2)/2}[/tex]
[tex]\sf{ x = 13 - 2(3)/2}[/tex]
[tex]\sf{ x = 13 - 6/2}[/tex]
[tex]\sf{ x = 7/2 }[/tex]
Therefore,
[tex]\sf{ Cost\: of \:8 \:drinks}[/tex]
[tex]\sf{ = 8 * 3/2 }[/tex]
[tex]\sf{ = 4 * 3 }[/tex]
[tex]\sf{ = 12.00 dollars}[/tex]
And
[tex]\sf{ Cost\: of \:9 \:hamburgers }[/tex]
[tex]\sf{ = 9 * 7/2 }[/tex]
[tex]\sf{ = 63/2}[/tex]
[tex]\sf{ = 31.50 dollars}[/tex]
Total cost of the 8 drinks and 9 hamburgers
[tex]\sf{ 12.00 + 31.50}[/tex]
[tex]\sf{\red { = 43.50 \:dollars}}[/tex]
Hence, The total cost paid by you for 8 drinks and 9 hamburgers is $43.50 .

Answer:
(0, -7) and (5, 0)
Step-by-step explanation:
y-intercept is when x = 0, therefore (0, -7)
x-intercept is when y = 0, therefore (5, 0)
Answer:
X intercept: (5,0) Y intercept: (0,-7)
Step-by-step explanation:
So you want to look at where you have an x value (input) and it's output (y) is 0 for x intercept, and you want to look at the y value (output) and it's input (x) to be 0 for the y intercept, so on the left we see that 5 = 0, and on the right we see that -7 = 0, and then write them as is, so (5,0) and (0,-7)

what is the 43rd term for 260,255,250
Answer:
43rd term = 50
Step-by-step explanation:
[tex]43rd \: term = 50[/tex]
The required 43rd term will be 50 in the given arithmetic sequence.
What is an arithmetic sequence?An arithmetic sequence is defined as an arrangement of numbers that is in a particular order.
The arithmetic sequence is given in the question as:
260, 255, 250...
This above sequence has:
The first number a₁ = 260
Common difference d = 255 - 260 = -5
The formula to find the general term of an arithmetic sequence is,
Tₙ = a₁ + (n-1)d ...(i)
Substitute the value of d = -5 and a₁ = 260 in the above formula
43rd term = 260 + (43-1)(-5)
43rd term = 260 - 42(5)
43rd term = 260 - 210
43rd term = 50
Therefore, the required 43rd term will be 50.

One equation in a system of equations is y=2x+10. Which equation below would have to be the second equation so that the system has infinitely many solutions?
Answer:
D
Step-by-step explanation:
y = 2x + 10 is the same thing as y = 2(x + 5) because 2 x x = 2x and 2 x 5 = 10
Simplify Option D
y=2(x+5)y=2x+2(5)y=2x+10As everything is same
i.e
A1/A2=B1/B2=C1/C2Hence infinitely many solutions are present
PLEASE HELP: find the minimum and maximum values for the function with the given domain interval
Answer:
I think that it's the third one.
Step-by-step explanation:
Answer:
minimum value = 0.001
maximum value = 10
Step-by-step explanation:
To find the minimum and maximum values for the function, substitute the endpoints of the domain into the function:
when x = -3:
[tex]\implies k(-3)=10^{-3}=0.001[/tex]
when x = 1:
[tex]\implies k(1)=10^{1}=10[/tex]
Therefore,
minimum value = 0.001
maximum value = 10
(5x2 + 23x - 7) - (x2 - 4x + 21) is equivalent to expression
4x² - 27x - 28 is the answer
Step-by-step explanation:
As per question,
(5x² + 23x - 7) - (x² - 4x + 21)
Removing the parentheses,
→ 5x² + 23x - 7 - x² + 4x - 21)
Now reorder and gather the like terms,
→ (5x² - x²) + (23x + 4x) + ( -7-21 )
Collecting the coefficients of like terms,
→ (5-1)x² - (23+4)x + ( -7-21 )
Calculating them now, we get,
→ 4x² - 27x - 28
So, (5x² + 23x - 7) - (x² - 4x + 21) = 4x² - 27x - 28
Match the terms to their definition.

Given the function f(x)=4x2−3x+4f(x)=4x2-3x+4. Calculate the following values:

f(−1)=f(-1)=
f(0)=f(0)=
f(1)=f(1)=
f(2)=f(2)=
Answer:
26, 11, 4, 5, 14
Step-by-step explanation:
To find the value of the function, replace the variable with the number and do the arithmetic.
f(-2) = 4(-2)² -3(-2) +4 = 16 +6 +4 = 26
For doing repetitive calculations, it is convenient to write the formula into a calculator or spreadsheet and let it work from the list of values. That is what we did in the attached. It shows a table of x and f(x) for the values of x you are interested in.
The function values are ...
f(-2) = 26f(-1) = 11f(0) = 4f(1) = 5f(2) = 14_____
Additional comment
For evaluating polynomials, either by hand or machine, it is often convenient to rewrite the polynomial in Horner Form. The total number of math operations tends to be reduced. When doing this by hand, the arithmetic tends to be easier.
f(x) = (4x -3)x +4
That is, the powers of x accumulate as each layer in parentheses is multiplied by x and the next coefficient added to the result.
Using this form, ...
f(-1) = (4(-1) -3)(-1) +4
f(-1) = (-7)(-1) +4 = 11

2. In a two-digit number, twice the tens digit is less than the units digit by 3. If the two digits are reversed, the new number is greater than twice the original number by 18. Find the original number
1) The pairs of numbers are:
19 and 91, which do not satisfy the condition
28 and 82, which do not satisfy the condition
37 and 73, which satisfy the condition
45 and 54, which do not satisfy the condition
The number is 37.
Another method:
10x+y+36 = 10y+x, or
9x+36 = 9y, or
x+4= y …(1)
x+y = 10, or
y = 10-x …(2)
Equate (1) and (2)
x+4 = 10-x
2x = 10–4 = 6, or x = 3 so y = 10–3 = 7.
So the number is 37
