Answer:
(x,y) = (2,3) so C?
Step-by-step explanation:
=> y = x/2+2
=> y = x + 1
from that info, you can tell y = y, meaning x/2 + 2 = x+1
solving:
=> x/2 + 2 = x + 1
=> 1/2x +2 = x + 1
=> -x -x
=> - 1/2x + 2 = 1
=> -2 -2
=> -1/2x = -1
=> * 2/-1 * 2/-1
=> x = 2
solve using substitution now:
(let's plug it in to the easiest y = statement)
=> y = x+1
=> y = 2 +1
=> y = 3
(2,3) is your answer
if line a is perpendicular to line b and the slope of line a is 7 whats the slope of line b
Answers
Answer:
If a line is perpendicular to another line, that means that the slope is completely opposite that of the original line. The first thing that we do to the slope is we negate the number which means that if we have a slope of [tex]-7[/tex] our slope because [tex]7[/tex] in this step. In our case our slope is [tex]7[/tex] so in this step it becomes [tex]-7[/tex].
Moving onto the second part which is to get the reciprocal of the number which means that if we have [tex]\frac{1}{2}[/tex] then we would switch it to [tex]2[/tex]. In our case our number is [tex]-7[/tex] so we would make that into a fraction like this [tex]-\frac{1}{7}[/tex].
In conclusion, our final slope of the perpendicular line is [tex]-\frac{1}{7}[/tex].
Hope this helps! Let me know if you have any questions
Answer: " [tex]-\frac{1}{7}[/tex] " .
_____________
Step-by-step explanation:
Assume we have a two-dimension Cartesian plane graph;
in which equations of straight lines can be expressed in the form of:
" y = mx + b " ;
in which:
"m" is the slope; as well as the "coefficient" of "x" ;
and: "b" is the y-intercept; that is, the value "y" value of the "(x, y)" coordinate at the point which "x = 0" ; that is, where the graph crosses the "y-axis".
Given the ^aformentioned conditions:
Note that if we select a line that can be written in the format:
" y = mx + b " ; then another line that is "perpendicular" to that
[selected line] will have the slope, "m"; of the value that is the "negative reciprocal value" of the slope, "m" ; of the other line.
Note that is our problem, we select a line—in our given problem:
"Line a" —with a slope, "m = 7 " ;
which is perpendicular to the slope of "Line b" ;
→ then: the slope of "Line B" ; would be the "negative reciprocal value"
of "7" .
Note: " [tex]7 = \frac{7}{1}[/tex] " ; the recriprocal would be: " [tex]-\frac{1}{7}[/tex] " .

Find the maximum value on (0, infinity) for f(x)=7x-2xlnx
Answers
f'(x)>0 for all x>0. Therefore f(x) is strictly increasing on the inverval (0,∞).
How to obtain the maximum value of a function?To find the maximum of a continuous and twice differentiable function f(x), we can firstly differentiate it with respect to x and equating it to 0 will give us critical points.
f(x) = max{0,x} then f(x)=0 if x<0 and f(x)=x if x≥0.
f(x)=7x-2xlnx
When x tends to -∞, f is the constant function zero, therefore limit n tends to infinity f(x) = 0.
When x tends to ∞, f(x)=x and x grows indefinitely. Thus limit n tends to infinity f(x) = infinity.
f is differentiable if x≠0. If x>0, f'(x)=1 (the derivative of f(x) = x and if x<0, f'(0)=0 (the derivative of the constant zero).
In x=0, the right-hand derivative is 1, but the left-hand derivative is 0, hence f'(0) does not exist,
f'(x)>0 for all x>0. Therefore f(x) is strictly increasing on the inverval (0,∞).

Find the area of the shaded region.
Use 3.14 for pi.
Answers
The area of the shaded region is 994.74 square in if the area of the circle is 1384.74 square in and the area of the triangle is 390 square in.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
As we know, the area of the circle is given by:
A = πr²
r = 21 in
A = 3.14(21)² = 1384.74 square in
Area of the triangle:
a = (39)(20)/2 = 390 square in
The area of the shaded region = 1384.74 - 390 = 994.74 square in
Thus, the area of the shaded region is 994.74 square in if the area of the circle is 1384.74 square in and the area of the triangle is 390 square in.

The radius of the circular mouse pad is 3.91 inches if the area of a circular mouse pad is 48 square inches.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have:
The area of the circular mouse pad = 48 square inches
The area of the circle:
[tex]\rm A = \pi r^2[/tex]
[tex]\rm 48 = \pi (r)^2[/tex]
Take π = 3.14

(4, 0) and (-2, 0)(1, -9)(0, -8)Step-by-step explanation:
Finding the x-intercepts :
y-value of the x-intercept is 00 = (x - 4)(x + 2)x - 4 = 0 ⇒ x = 4x + 2 = 0 ⇒ x = -2The x-intercepts are : (4, 0) and (-2, 0)Finding the vertex :
Expanding the function ff(x) = (x - 4)(x + 2)f(x) = x² - 4x + 2x - 8f(x) = x² - 2x - 8Vertex = (h, k)h = -b/2a = -(-2)/2(1) = 1k = (1)² - 2(1) - 8k = 1 - 2 - 8 = -9The vertex is : (1, -9)Finding the y-intercept :
Substitute x = 0 in the functionf(0) = 0² - 2(0) - 8f(0) = -8The y-intercept is : (0, -8)In order to find x-intercept, the f(x) or y will be 0
=================
(x-4)(x + 2) = 0
(x-4) = 0, (x + 2) = 0
x = 4, x = -2
x intercepts: (4, 0) and (-2, 0)
2) What is the ordered pair of the vertex?In order to find vertex use the formula: x = -b/2a
y = (x-4)(x + 2)
y = x² -4x + 2x -8
y = x² - 2x -8
Now find x-coordinate of vertex:
x = -(-2)/2(1)
x = 2/2
x = 1
y coordinates: (1-4)(1 + 2) = -9
Ordered pair of vertex: (1, -9)
3) What is the y intercepts of the graph?In order to find y intercept, insert x = 0
y = (0-4)(0 + 2)
y = -8
y intercept: (0, -8)

This is a set of rules for order of expressions that is taught to a large number of students at the advance arithmetic and early algebra phases of their schooling. For the expression given in the question it directs:
6/2(1 + 2) = 6/2(3) —Do what is in the parentheses first.
= 6/2(3) — No change because next come handling exponents, of which there are none.
= 3(3) —Do multiplications and divisions in order from left to right.
= 9. —Repeating previous step since there is one division and one multiplication.
There are problems with this set of rules because they were designed for advanced arithmetic and early algebra. They do not handle more advanced expressions. For advanced arithmetic, typically all operations are expressed explicitly, so that 6/2(1 + 2) would not be given, but instead 6/2 × (1 + 2). We will see in the next convention how this distinction can be important, and standard PEMDAS/BODMAS do not distinguish the two expressions

B. What is the probability that one of the balls selected is the number 5?
Answers
Answer:
A=1000

A. The total numebr of ways or permutaion selecting three balls from the bag without replacement is 720.
B. The probability of getteing a ball or selecting a ball marked with number five is [tex]\frac{1}{5}[/tex].
What is permutation?A permutation is a mathematical technique that determines the number of possible arrangements in a set when the order of the arrangements matters.
What is th eformula for permutation?The formula for the permutation is
[tex]^{n} P_{r} = \frac{n!}{(n-r)!}[/tex]
Where,
n is the total number of objects
r is the total number of selected students
[tex]^{n} P_{r}[/tex] is the total number of permuations
What is probability?The probability is the measure of the likelihood of an event to happen. It measures the certainty of the event. The formula for probability is given by; P(E) = Number of Favourable Outcomes/Number of total outcomes.
According to the given question.
Total number of balls in a bag = 10
A. Three balls are selected at a randow.
Since, repetition is not allowed or replacement is not allowed.
So, the number of ways selecting the first ball is 10
Number of ways selectiong the second ball is (10-1)
Number of ways selecting the third ball is (9-1)
Therefore,
The total number of ways or permutation selecting three balls from a bag
= [tex]^{10} P_{3}[/tex]
[tex]= \frac{10!}{(10-3)!}[/tex]
[tex]= \frac{10!}{7!}[/tex]
[tex]=\frac{10\times 9\times 8\times 7!}{7!}[/tex]
[tex]= 10\times 9\times 8[/tex]
[tex]= 720[/tex] ways
Hence, the total numebr of ways or permutaion selecting three balls from the bag without replacement is 720.
B.
Total number of ball in a bag = 10
Total number of ball in a bag marked with 5 = 1
Thereofre,
the probability of selecting a ball marked with number 5
= [tex]\frac{total\ number\ of \ balls\ marked\ with \ number\ five\ }{total\ number\ of\ balls\ in\ a \ bag}[/tex]
[tex]= \frac{1}{5}[/tex]
Hence, the probability of getteing a ball or selecting a ball marked with number five is [tex]\frac{1}{5}[/tex].
