translated left 7, down 3 from f(x)
Step-by-step explanation:
When the graph of function f(x) is translated right h units and up k units, the new graph is of the function ...
g(x) = f(x -h) +k
Comparing this to the given g(x), we see h=-7, k=-3.
The graph of g(x) is the graph of f(x) translated left 7 units and down 3.

What is the value of k such that x - 7 is a factor of f(x) = 2x3 - 13x2 - kx + 105?
Show all computation and justify your answer.
Answers
2x³ - 13x² -kx + 105
since x - 7 is a factor, therefore x - 7 = 0 ; x = 7
Substitute the value for x in the equation.
i.e f(x) = 2x³ - 13x² -kx + 105
f(7) = 2(7)³ - 13(7)² - k(7) + 105
0 = 2(343) - 13(49) - 7k + 105
0 = 686 - 637 - 7k +105
0 = 154 - 7k
7k = 154
k = 154/7
k = 22
2x³ - 13x² -kx + 105
since x - 7 is a factor, therefore x - 7 = 0 ; x = 7

Graph and solve x+2y=4, x-2y=-8
Answers
Answer:
(x, y) = (-2, 3)
Step-by-step explanation:
In this form, it is easy to determine the x- and y-intercepts of each equation. That makes it easy to graph the first one, but not so easy to graph the second one on the given form.
The x-intercept is found by solving for x when y=0. In the two equations, the x-intercepts are ...
x = 4
x = -8 . . . . . . not shown on the given grid
__
The y-intercepts are found by solving for y when x=0. In the two equations, the y-intercepts are ...
y = 4/2 = 2
y = -8/-2 = 4
__
For the second equation, you can solve for y to put it in slope-intercept form.
x -2y = -8
x +8 = 2y . . . . . add 2y+8
y = 1/2x +4 . . . . . . . slope = 1/2, y-intercept = 4 (which we already knew)
This means the graph of the second equation will have a rise of 1 for each run of 2 units to the right. Working to the left from the y-intercept, we find another point to be (-2, 3), a point 2 left and 1 down from the y-intercept. This point is also on the line produced by the first equation, so (-2, 3) is the solution to the system.
Jason is a salesperson who sells computers at an electronics store. He
makes a base pay amount each day and then is paid a commission as a
percentage of the total dollar amount the company makes from his
sales that day. The equation P = 100 + 0.03% represents Jason's
total pay on a day on which he sells x dollars worth of computers.
What is the y-intercept of the equation and what is its interpretation in
the context of the problem?
Answers
Answer:
y-intercept: 100
100 is Jason's base pay amount
Step-by-step explanation:
In the given equation, the term 100 does not depend on x, the value of computers sold. The pay is said to consist of base pay plus commission that depends on sales. The term that has a dependence on sales is 0.03x, so the other term in Jason's pay equation must be his base pay.
The y-intercept is $100, Jason's daily base pay.

There are 165 counters in a bag. Each counter is either black or white.
There are twice as many black counters as white counters in the bag. Martine takes 40% of the black counters from the bag.
Work out the ratio of the number of black counters to the number of white counters now in the bag.
Give your ratio in its simplest form.
Answers
6:5
there are 165 counters in the bag.
let the white counter be x
the black counter = 2x2x + x = 165
3x=165divide both sides by 3
x=55there are 55 white counters in the bag
165-55=110
OR
2x= 165
divide both sides by 2
x= 110
there are 110 black counters in the bagMartine takes 40%of the black counter40%= 40/100×110
= 44.
44 black counters was taken out of the bagthen there would be 66 black counters left I.e(110-44=66)▪︎ there would be 66 black and 55 white counters in the bag.
ratio of black counters to the white counter = 66:55reduced to the lowest term = 6:5 ( 11 divides 66 and 55 Into 6 and 5)• the answer is 6:5

What is a linear function?The question is an illustration of a linear function; a linear function is a function that has a constant rate/slope
A linear function is represented as:
[tex]y=mx+c[/tex]
Where
m represents slopec represents the y-interceptThe slope is calculated as:
[tex]m = \frac{y_2 -y_1}{x_2 -x_1}[/tex]
So, we have:
[tex]m = \frac{576 - 64}{18-2}[/tex]
[tex]m = \frac{512}{16}[/tex]
[tex]m = 32[/tex]
The linear equation is then calculated as:
[tex]y =m(x -x_1) + y_1[/tex]
So, we have:
[tex]y =32(x -2) + 64[/tex]
[tex]y =32x -64 + 64[/tex]
[tex]y =32x[/tex]
Hence, the equation that represents the linear function is y =32x

in a bag, there are 4 green balls, 6 brown balls and 8 white balls. What is the probability that a child picks a brown ball?
Answers
Answer:
6/18 or 1/3
Step-by-step explanation:
there are 18 balls and 6 brown balls so it will be 6/18 or 1/3
Answer:
6/18 or 1/3 if simplified
Step-by-step explanation:
In order to find this, all you have to do is add up all the numbers and then write it as a fraction.
So since 4+6+8= 18 and there are only six brown balls, the probability would be written as 6 (number of brown balls) over 18 (total number of balls)
