Answer:
the slope would be 17
Step-by-step explanation:
he earns $17 per hour
you find this by dividing the amount earned by the hours worked
102 / 6 = $17 per hour
187 / 11 = $17 per hour

Which polynomial is in standardare form?
Answer:
[tex]x^5y^5-3xy-11x^2y^2+12[/tex]
Step-by-step explanation:
What does a polynomial being in standard form mean?
It means that the terms are ordered from highest degree to lowest.
In this case, it would be the 3rd option ([tex]x^5y^5-3xy-11x^2y^2+12[/tex]) since it's the only option where all of the terms have a descending order of degrees.
Good luck!

What's the GCF of 8bc and 17abc?
The GCF of "8bc" and "17abc" would be "bc" which is determined by prime factorization.
What is Prime Factorization?Prime Factorization is defined as any number that may be expressed as a product of prime numbers that has been said to be prime factorized. Any integer with exactly two factors 1 and the number itself. is said to be a prime number.
We have to determine the GCF of 8bc and 17abc
We need to write 8bc and 7abc as the product of their prime factors
Prime factorization of the given numbers:
⇒ 8bc = 2 × 2 × 2 × b × c
Here 8 is 2 × 2 × 2
⇒ 7abc = 7 × a × b × c
GCF (8bc, 7abc) :
= b × c
= bc
Therefore, the GCF of "8bc" and "17abc" would be "bc" which is determined by prime factorization.

-x2 - 4x + 21
Factorise
9514 1404 393
Answer:
-(x -3)(x +7)
Step-by-step explanation:
Apparently, you're supposed to match the given expression with the parts of the identity ...
(x + a)(x + b) = x² +(a +b) +ab
First of all, we notice that the sign of x² in our given expression is negative. So, we factor -1 out of the expression first.
-x² -4x +21 = -(x² +4x -21)
Now, matching the coefficients of x, and the constant to those in our identity, we see ...
a + b = 4 . . . . . coefficients of x
ab = -21 . . . . . . constants
It is relatively easy to find the factors of -21. We are interested in those factor pairs such that the sum is positive:
-21 = -1(21) = -3(7) = -7(3) . . . . at this point the sum -7+3 becomes negative
The factor pair a=-3, b=7 will satisfy ...
a + b = -3 + 7 = 4
ab = (-3)(7) = -21
So, our factorization is ...
-x² -4x +21 = -(x² +4x -21) = -(x -3)(x +7)

Brayden and Aubrey are both driving along the same highway in two different cars to a stadium in a distant city. At noon, Brayden is 280 miles away from the stadium and Aubrey is 340 miles away from the stadium. Brayden is driving along the highway at a speed of 30 miles per hour and Aubrey is driving at speed of 40 miles per hour. Let
B
B represent Brayden's distance, in miles, away from the stadium
t
t hours after noon. Let
A
A represent Aubrey's distance, in miles, away from the stadium
t
t hours after noon. Graph each function and determine the number hours after noon,
t
,
t, when Brayden and Aubrey are the same distance from the stadium.
Answer:
B(t) = -30t + 280
A(t) = -40t + 340
(Screenshot of graph is attached below)
They will be the same distance away from the stadium after 6 hours.

The makers of a soft drink want to identify the average age of its consumers. A sample of 25 consumers was taken. The average age in the sample was 31 years with a standard deviation of 3.8 years. The Margin of error of the 99% confidence interval for the average age of the consumers is
Step-by-step explanation:
d_f=25-1=24
critical t value=tinv (0.05,24)=2.064
Margin of error=2.064×(3.8/sqrt(25))=1.86
99% confidence interval for mean
=22.5+/-1.86

g(x) = -1/2x+k. If g(4)=11, what is the value of k?
Answer:
89/8
Step-by-step explanation:
Given,
g(x)=-1/2x+k
g(4)=11
k=?
now,
g(x)=-1/2x+k
or,g(4)=-1/2×4+k
or,11=-1/8+k
or,11+1/8=k
or,k=89/8.ans
Write the equation in slope intercept form
Answer: y = -5x + 6
Step-by-step explanation:
(1, 1), (2, -4), and (0, 6) are the points on your graph
slope (m) = (y2 - y1) / (x2 - x1)
m = -4 - 1 / 2 - 1 = -5/1 = -5
y = mx + b
y = -5x + b
(0,6) would be your y-intercept because it is on the y-axis
in y = mx + b, b is always the y-intercept
y = -5x + 6
* you can also plug (1, 1) or (2, -4) into y = -5x + b and solve for b
what are the equation in poiny slope form for the line parrelle to y=3x-4 that contains j(-9,2)
Answer:
y-2=3(x+9)
Step-by-step explanation:
ok, first of all, parallel lines have the same slope.
point slope form is y-y1=m(x-x1) (m is the slope)
so we know the slope is 3
and the point is (-9,2)
plug everything in
y-2=3(x+9)
Hope this helps! Sorry for my mistake earlier
