Answer:
y = 4/3x + 1
Hope this helps :)
Step-by-step explanation:
The slope-intercept form is y = mx + b.
m = the slope which is 4/3
b = the y-intercept which is 1
So to substitute the numbers in, the final equation would be y = 4/3x + 1
what is the greatest common factor of 18 and 24 with 18/24 in the simplest form i do not understand how to do this
Answer:
Greatest common factor: 6
The simplest form of 18/24 = 3/4
Explanation:
First, we need to identify the factors of 18 and 24. The factors are the numbers that divide 18 and 24.
Factors of 18: 1, 2, 3, 6, 9, 18
Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24.
Then, the common factors are: 1, 2, 3, and 6
Finally, the greatest common factor is 6.
On the other hand, if we want to write 18/24 in the simplest form, we need to divide both numbers by the greatest common factor, so:
[tex]\frac{18\div6}{24\div6}=\frac{3}{4}[/tex]So, 18/24 in the simplest form is 3/4
For a standard normal distribution, given:
P(z < c) = 0.9663
Find c.
The value of c for a standard normal distribution, P(z < c) = 0. 9663 is 0.47.
What is standard normal distribution?
The standard normal distribution table gives the probability of a regularly distributed random variable Z, whose mean is equivalent to 0 and difference equal to 1, is not exactly or equal to z. The normal distribution is a persistent probability distribution.
What is z score?
Z score is used to determine by how many standard deviations the raw score is above or below the mean. It is given by
z = (x - μ)/σ
Where x is the raw score, μ is the mean and σ is the standard deviation.
Given that P(z < c) = 0. 9663; hence:
From the normal distribution table, c = 0.47
The value of c for a standard normal distribution, P(z < c) = 0. 9663 is 0.47.

Find the x-and y-intercepts.3x – 2y =-6The x-interceptisThe y-intercept is
The x-intercept -2 is and the y-intercept is 3
Here, we are tasked by finding the x-intercept and the y-intercept of the given straight line
The x-intercept is the point on the graph where we have the coordinates as (x,0)
What this mean is that at the x-intercept, the value of y = 0
Thus by substituting y = 0 into the equation, we can get the value of the x-intercept
Making the substitution, we have
3x - 2(0) = -6
3x = -6
x = -6/3
x = -2
The y-intercept is the point on the graph where we have the coordinates as (0,y)
What this mean is that at the y-intercept, the value of x = 0
Thus by substituting x = 0 into the equation, we can get the value of the y-intercept
Making the substitution, we have
3(0) - 2y = -6
-2y = -6
divide both sides by -2
y = -6/-2
y = 3
For the curve, estimate the instantaneous rate of change at x=5 without the use of derivatives
Answer: -0.733
Step-by-step explanation:
To estimate the instantaneous rate of change, we can take the slope of the secant through two points on the curve that are close to x=5.
In this case, we will consider [tex](4.9, f(4.9))[/tex] and [tex](5.1, f(5.1))[/tex].
[tex]\frac{f(5.1)-f(4.9)}{5.1-4.9} \approx -0.733[/tex]

Explanation
The slope of the line can be calculated with:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]where (x₁, y₁) and (x₂, y₂) are the two points given. Then:
• x₁ = 9
,• y₁ = –4
,• x₂ = 1
,• y₂ = –5
Thus, replacing the values and simplifying:
[tex]m=\frac{-5-(-4)}{1-9}[/tex][tex]m=\frac{-5+4}{-8}[/tex][tex]m=\frac{1}{8}[/tex]Which choice is equivalent to the fraction below? (Hint: Rationalize the denominator and simplify.)A.B.C.2D.
Given: A fraction

Explanation: The given fraction can be simplified by rationalizing the denominator of the fraction. The rationalizing factor is
[tex]2-\sqrt{2}[/tex]Hence,
[tex]\begin{gathered} \frac{(2-\sqrt{2})}{2+\sqrt{2}}\times\frac{(2-\sqrt{2})}{(2-\sqrt{2})} \\ \frac{(2-\sqrt{2})^2}{(2)^2-(\sqrt{2}^{)2}} \end{gathered}[/tex]Which gives
[tex]\begin{gathered} \frac{4+2-4\sqrt{2}}{4-2} \\ \frac{2(3-2\sqrt{2})}{2} \\ 3-2\sqrt{2} \end{gathered}[/tex]Final Answer: Option A is correct.
At an aquarium, researchers are preparing a mixture of salt water. The desired ratio is 90 grams of salt per liter of water.1 ounce= 28.35 grams1 gallon= 3.8 literswhat is the ratio in ounces per gallon
Based on the question, the ratio of the salt mixture is:
[tex]\frac{90grams}{1\text{liter}}[/tex]So, if we have 3.8 liters in 1 gallon, we would need 90grams x 3.8 = 342 grams of salt in 1 gallon.
[tex]\frac{90grams}{1\text{liter}}\times\frac{3.8liters}{1\text{gal}}=\frac{342grams\text{ }}{1gal}[/tex]The next step is to determine how many ounces are there in 342 grams. If 1 ounce = 28.35 grams, then 342 grams divide 28.35 grams = 12.06. Hence, in 342 grams, there are 12.06 ounces.
Thus, we can say that:
[tex]\frac{342\text{grams}}{1\text{gal}}=\frac{12.06\text{ounces}}{1\text{gal}}[/tex]The ratio of the salt mixture is 12.06 ounces per gallon.

The Rodriguez family has a fixed incomeof $4,000 a month. Their fixed expensesare $1,800 a month. They save at leastone fourth of the remaining income eachmonth. What is the minimum amountsaved by the Rodriguez family in a year?
we know that
The Rodriguez family has a fixed income of $4,000 a month.
Their fixed expenses are $1,800 a month
so
The remaining amount in a month is
4,000-1,800=$2,200
The one fourth of the remaining income is
(1/4)(2,200)=$550
To find out the minimum amount in a year, multiply $550 by 12
550*(12)=$6,600
therefore
the answer is$6,600Find the zeros by using the quadratic formula and tell whether the solutions are real or imaginary. F(x)=2x^2+6x–16

[tex]\begin{gathered} 16=a\cdot b^1 \\ so \\ 16=a\cdot b \end{gathered}[/tex]and by substituting point (5,1296), we get
[tex]1296=a\cdot b^5[/tex]Then, we have 2 equations in 2 unknonws:
[tex]\begin{gathered} a\mathrm{}b=16 \\ a\mathrm{}b^5=1296 \end{gathered}[/tex]By isolating a from the first equation and substituting this result into the second one, we get

The value of k is 4 , the line through (-1,k) and (-7, -2).
Given,
The line through (-1, k) and (-7, -2) is parallel to the line y = x + 1.
To find the value of k
Now, According to the question is:
For Parallel lines, We know that
It has same slope as y = x + 1
Also, We know y = x +1 has slope of 1.
Using the formula for the slope :
m = [tex]\frac{y_{2} - y_{1} }{x_{2} - x_{1} }[/tex]
Now, For value k
We have, 1 = (-2-k)/(-7-1)

Mai works a total of 31 hours per week at two jobs. The number of hours she works at a coffee stand is 5 less than 2 times the number of hours she works at the animal shelter. How many hours does Mai work at the animal shelter?
Show the equation you use and your work solving the equation.
Answer:
12
Step-by-step explanation:
Let x = number of hours at the shelter
"The number of hours she works at a coffee stand is 5 less than 2 times the number of hours she works at the animal shelter."
The number of hours at the coffee stand is
2x - 5
The total number of hours is 31, so x added to 2x - 5 must equal 31.
2x - 5 + x = 31
3x - 5 = 31
3x = 36
x = 12
She works 12 hours at the shelter.

How many units can be obtained from f(x) =|x+7|−6 if the graph has been shifted down and left?
The translation we need to get f(x) is a translation of 7 units to the left and 6 units down.
Which shift do we have here?I assume we want to identify the transformation that we need to apply to the parent absolute value function |x| in order to get f(x).
Remember that a horizontal translation of N units and a vertical translation of M units is written as:
y = |x - N| + M
In this case we have:
f(x) = |x + 7| - 6
Comparing it with the formula above, we get:
N = -7
M = -6
