9.5=25/t+(-8) helppppppppp
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
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.

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)
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].

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
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

y = 5x - 1 and
-5x = -1-y put in you first!
Point of Intersection:
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

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?
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
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.
Please help me anyone I’m kinda stuck
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
