Answer:
z's exponent = 5
Step-by-step explanation:
the degree of monomial is basically all of the exponents added up
so:
x's exponent + y's exponent + z's exponents = the degree
So:
1+2+z's exponent = 8
(since x to the power of 1 = x)
3+z's exponent = 8
Subtract 3 from each side:
z's exponent = 5

x = 3
Step-by-step explanation:
x + 4 = 7 ( isolate x by subtracting 4 from both sides )

Pls, mark it as the brainliest. I need it.Which of the following functions best describes this graph?
A. y = (x - 3)(x + 1)
B. y = x - x +5
C. y = x? -5x + 6
D. y = (x - 1)(x - 1)
Answers
Answer: D: Y=(x-1)(x-1)
Step-by-step explanation:
The function described by the graph is [tex](x-1)^2[/tex].
Therefore, the correct answer is Option D. y = ( x - 1 ) ( x - 1 )
Given data:
The function is represented as f(x) = y
Now, the value of f(x) is plotted below:
To plot the graph, start by determining some key points and then connecting them.
When x = 0:
f(0) = 1
So, the point is (0, 1).
When x = 1:
f(1) = 0
So, the point is (1, 0).
When x = 2:
f(2) = 1
So, the point is (2, 1).
The graph of [tex]f(x) = (x - 1)^2[/tex] is a parabola that opens upwards. The vertex of the parabola is at the point (1, 0), which corresponds to the minimum value of the function.
As x moves further away from 1 in either direction, the function increases.
Hence, the parabolic function is [tex]f(x) = (x - 1)^2[/tex].

y = 5x - 1 and
-5x = -1-y put in you first!
Point of Intersection:
Answers
Answer: (0; - 1)
Step-by-step explanation:
y = 5x - 1 and 5x = - 1 - y
y = - 1 - 5x
5x - 1 = - 1 - 5x
5x = -5x
5x + 5x = -5x + 5x
10x = 0
x = 0
y = 5x - 1
y = 5 × 0 - 1 = - 1
9.5=25/t+(-8) helppppppppp
Answers
Answer:
437.5Step-by-step explanation:
I will REALLY answer your question :)
9.5 = 25/t + -8
The first step here is to simplify t + -8. If you add a negative of something, you also subtract. This can be rewritten as:
9.5 = 25/t - 8
Now, we need to add 8 to undo the subtraction.
17.5 = 25/t
Now, to undo the division, we will multiply the whole equation by 25.
17.5 x 25 = 437.5
In the triangle ABC , Angle A = 46° and Angle B = 83°. How large is the exterior angle at C?
This is a problem with no diagram
Answers
Answer:
180 - 46 - 83 = 51 is the measure of angle C
the exterior angle at angle C, and angle C, are supplementary. since angle C is 51 because of the interior angle triangle sum theorem, then the exterior angle is: 180 -51 = 129 degrees.

On Thursday, a local hamburger shop sold a combined total of 417 hamburgers and cheeseburgers. The
number of cheeseburgers sold was two times the number of hamburgers sold. How many hamburgers were
sold on Thursday?
Answers
Let H represent Hamburgers.
Let cheeseburgers represent 2H .
H + 2H = 417
3H = 417
H = 417/3
H = 139 hamburgers
2H = 2 * 139 = 278 cheeseburgers
Therefore, there were 139 hamburgers sold on Thursday.

) Luci Lulu opened a cookie store in the mall. She found that the relationship between the price of a cookie, p, and the number of cookies sold, x, is given by the linear relationship x = −2000 p + 4000 . Find the maximum revenue Luci can make selling cookies in one day
Answers
Answer:
The maximum revenue Luci can make selling cookies in one day is $4,004,000.
Step-by-step explanation:
Given;
x = −2000 p + 4000 ..................... (1)
Revenue = xp
Revenue = (−2000 p + 4000)p =
Revenue = −2000p^2 + 4000p .................... (2)
The price at which Luci will the maximum profit can be calculated by finding the derivative of equation (2), equating to 0, and then solve for p as follows:
−4000p + 4000 = 0
4000 = 4000p
p = 4000 / 4000
p = 1
This implies that the price at which Luci will the maximum profit is $1.
Substituting p = 1 into equation (2) to obtain the maximum revenue Luci can make selling cookies in one day, we have:
Revenue = (−2000 * 1)^2 + (4000 * 1)
Revenue = −2000^2 + 4000
Revenue = 4,000,000 + 4000
Revenue = 4,004,000
Therefore, the maximum revenue Luci can make selling cookies in one day is $4,004,000.

The length of a rectangle is 3x-4 and the width is x. The perimeter is 72 feet. What is the measure of the length?
Answers
First, you would have to set an equation to find the value of x. To find this equation you would multiply both expressions for length and width by two. You would get the expression (6x-8) for length and the expression (2x) for width. You would then add these and make them equal to the perimeter, 72. You would get the equation 8x-8=72. Solving this equation would give you x=10. You just plug this value of x into the expression for length, which gives you the answer 26 ft.
Answer:
26 is your answer. I hope this helps!

A bag contains cards numbered from 1 to 14 one card is drawn at random find the probability of
a.) Selecting a prime number of a multiple of four
b.) selecting a multiple of two or a multiple of three
Answers
Answer:
One: P = 1/2 = 0.5
Two: P = 8/14 = 4/7 = 0.714
Step-by-step explanation:
One
I take it that the question is a prime number or 4.
P(four) = 1/14
The primes are 2,3,5,7,11,13. There are 6 of them
P(prime) = 6/14
P(prime or four) = 6/14 + 1/14 = 7/14 = 1/2
Two
Multiple of 2 := 2 4 6 8 10 12 14
Multiple of 3 := 9 in addition to 6 and 12 which cannot be counted twice.
P(2 or 3) = 8/14 = 4/7 = 0.714
