The linear function g is defined by g(x) = 4x.
a. Determine g(3).
b. Determine g(2).
c. Determine g(3) - g(2)
Answer:
the answer is D.
Step-by-step explanation:
well, the y-intercept for f(x) is at
as you can see from the slope-intercept form is at 4, and it has an slope of 2/3.
for g(x), well an y-intercept is when x = 0, what is it from that table? well, is at 0,3, so when x = 0, y = 3, so no dice on that one.
c)
whenever an x-intercept occurs, y = 0, for f(x) that's at
what about the x-intercept for g(x)? well, let's check, when is y = 0? aha! at -9, 0, so when y = 0, x = -9, so no dice on that one either.
d)
well, what is the slope of g(x) anyway? well, let's pick two points off the table to get it hmmm the first two let's use,
and from a), using the slope-intercept form, we know f(x) has a slope of 2/3.
well, 2/3 is larger than 1/3, so no dice.
b)
well, you already know.

c) $500 is earned for every 8 hours worked 0 d) $300 is earned after working 4 hours
Answer:
C.
Step-by-step explanation:
❌Option A is incorrect
Rationale: from the graph, 1 hr on the x-axis doesn't correspond to $100 on the y-axis
❌Option B is incorrect
Rationale: from the graph, 2 hrs on the x-axis doesn't correspond to $200 on the y-axis. It can't also be the unit rate because unit rate would be the amount of dollars per 1 hr.
✅Option C is CORRECT
Rationale: from the graph, 8 hrs on the x-axis corresponds to $500 on the y-axis
❌Option D is incorrect
Rationale: from the graph, 4 hr on the x-axis doesn't correspond to $300 on the y-axis
Which shows a graph of a linear equation in standard form Ax + By = C, where A = 0, B is positive, and C is negative? A coordinate plane with a vertical line passing through (1, negative 4), (1, 0) and (1, 4). A coordinate plane with a vertical line passing through (negative 2, negative 4), (negative 2, 0) and (negative 2, 4). A coordinate plane with a horizontal line passing through (negative 4, 4), (0, 4) and (negative 4, 4). A coordinate plane with a horizontal line passing through (negative 4, negative 3), (0, negative 3) and (4, negative 3).
Answer:
A coordinate plane with a horizontal line passing through (negative 4, negative 3), (0, negative 3) and (4, negative 3).
Step-by-step explanation:
Ax + By = C, where A = 0, B is positive, and C is negative
By= C or y= C/B which is negative
Since A is zero and C is negative, the line is parallel to x- axis and has negative value for y, so it is a horizontal line below zero
---------------
A coordinate plane with a vertical line passing through (1, negative 4), (1, 0) and (1, 4).
no, the line is horizontal
A coordinate plane with a vertical line passing through (negative 2, negative 4), (negative 2, 0) and (negative 2, 4).
no, the line is horizontal
A coordinate plane with a horizontal line passing through (negative 4, 4), (0, 4) and (negative 4, 4).
no, the y-values should be negative
A coordinate plane with a horizontal line passing through (negative 4, negative 3), (0, negative 3) and (4, negative 3).
yes, this is horizontal line below zero

While watching the Kentucky Derby horse races, you decide to guess who will win 1st, 2nd, and 3rd place. There are 17 horses in the race. What is the probability you choose all three places correctly
Answer:
1/17
Step-by-step explanation:
I he had even got 1 out of the 3 places the probability would be 3/17
But as he is guessing all three places it becomes 1/17
The probability of getting the 1st,2nd, and 3rd position will be 1/17.
What is the probability?Probability is defined as the ratio of the number of favorable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Given that while watching the Kentucky Derby horse races, you decide to guess who will win 1st, 2nd, and 3rd place. There are 17 horses in the race.
The probability is calculated by the formula,
Probability = Number of favorable outcomes / Number of sample
Number of favorable outcomes = 1
Number of samples = 17
Probability = Number of favorable outcomes / Number of sample
Probability = 1/17
Therefore, the probability of getting the 1st,2nd, and 3rd position will be 1/17.

Analyze the diagram below and complete the instructions that follow.
Find a, b, and c.
Answer:
Step-by-step explanation:
for side a
take 60 degree as reference angle
using tan rule
tan 60 =opposite /adjacent
[tex]\sqrt{3}[/tex] = a/6
do cross multiplication
6*[tex]\sqrt{3}[/tex] =a*1
[tex]6\sqrt{3} = a[/tex]
for b
using pythagoras theorem
a^2 + b^2 =c^2 (here a nd b are the legs of a right triangle and c is hypotenuse)
6^2 + [tex](6\sqrt{3})^2 = b^2[/tex]
36 + 6*6*3 = b^2
36 + 108 = b^2
144 = b^2
[tex]\sqrt{144}[/tex] = b
14 = b
for angle c
take 45 degree as reference angle
using cos rule
cos 45 = adjacent/hypotenuse
[tex]\frac{1}{\sqrt{2} } = \frac{c}{12}[/tex]
do cross multoplication
[tex]c*\sqrt{2} = 12*1[/tex]
[tex]c = \frac{12}{\sqrt{2} } \\\\c = 6\sqrt{2[/tex]

Simplify: [3(2a)^3/2]^2
A: 34^4√2a^9
B: 72a^3
C: 216a^3
D: 24a^3
==================================================
Explanation:
We have something of the form [M*N]^2 where M = 3 and N = (2a)^(3/2)
Squaring the M leads to M^2 = 3^2 = 9
Squaring the N leads to N^2 = (2a)^3 = 8a^3
Notice how the fractional exponent goes away. The denominator '2' cancels with the '2' from the squaring operation
In other words, the rule is [tex]\left(x^{1/2}\right)^2 = x[/tex] where x is nonnegative.
A more general form of the rule is [tex]\left(x^{p/2}\right)^2 = x^p[/tex]
-------------
After squaring M and N, we then get to
[MN]^2 = M^2*N^2 = 9*8a^3 = 72a^3

Amber is solving the inequality X+61- 12 < 13 by graphing. Which equations should Amber graph?
O Y1 = +6 Y2 - 25
O y1= x+6y2 = 25
O Y1 = X+61.72 = 13
O Y1 = X+6.82 = 13
Therefore, Amber should graph the equation Y1 = X+61.
What is inequality?An inequality is a mathematical statement that compares two values or expressions using one of the inequality symbols: < (less than), > (greater than), ≤ (less than or equal to), ≥ (greater than or equal to), or ≠ (not equal to). Inequalities are used to describe a range of possible values for a variable, rather than a single value. Inequalities can be solved by performing operations on both sides of the inequality symbol, just like equations. However, there are some important differences between solving equations and solving inequalities. For example, if we multiply or divide both sides of an inequality by a negative number, we need to reverse the direction of the inequality symbol.
Here,
To graph the inequality X+61- 12 < 13, we need to rearrange it to the form Y < MX + B, where Y is on the left-hand side and X is on the right-hand side. This gives:
Y < -X + 64
Now we can graph the line Y = -X + 64 and shade the region below it, since we want Y to be less than this expression.
Out of the equations given, Y1 = X+61 is the closest to the inequality we are trying to graph. However, the coefficients of X and Y are reversed, so we need to rearrange it to the desired form:
Y - X < 61
Y < X + 61
