given the function g(x)=3x-7, determine when g(x)=-4
Answers
You have the following function:
g(x) = 3x - 7
In order to determine th value of x when g(x) = -4, you equal the previous expression to -4 and solve for x, just as follow:
g(x) = 3x - 7 replace g(x) = -4
-4 = 3x - 7 add 7 both sides
-4 + 7 = 3x simplify
3 = 3x divide by 3 both sides
3/3 = x
x = 1
Hence, the anser is x = 1
A student earned grades of C, A, B, and A in four different courses. Those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. The grading system assigns quality points to letter grades as follows: A = 4, B = 3, C = 2, D = 1, and F = 0. Compute the grade point average (GPA) and round the result to two decimal places.2.183.408.753.50
Answers
Given:
Grades the student earned = C, A, B, A
Corresponding credit hours = 4, 5, 1, 5
The grading system assigns quality points to letter grades as follows: A=4, B=3, C=2, D=1, and F=0.
Required: Grade point average (GPA)
Explanation:
Points earned = Earned grades x Corresponding credit hours
For C, points earned = 2 x 4 = 8 points
For A, points earned = 4 x 5 = 20 points
For B, points earned = 3 x 1 = 3 points
Total points earned = 8+20+3+20 = 51 points
Total credit hours = 4+5+1+5 = 15 hours
Find GPA.
[tex]\begin{gathered} \text{Grade point average\lparen GPA\rparen=}\frac{\text{ Total points of the student}}{\text{ Total credit hours}} \\ =\frac{51}{15} \\ =3.40 \end{gathered}[/tex]Final Answer: The grade point average of the student is 3.40.
6 cm 4 cm 10 cm What is the area of the figure in square centimeters? TOTAL AREA= find the area of all the shapes and ADD together. To find the area 1/2 of a circle , you need the area of a circle and divide by 2. USE YOUR FORMULA CHART.
Answers
Notice that since the bottom side of the figure has a length of 10cm while the part that corresponds to the rectangle is only 6cm long, then the base of the triangle is 4cm long. The height of the triangle is 4cm long, since it is the same as the height of the rectangle. Additionally, the diameter of the semicircle turns out to be equal to 4cm, then its radius (which is half the diameter) must be 2cm long.
Use these data to find the area of each figure:
Semicircle
The area of a semicircle is half the area of a circle:
[tex]\begin{gathered} A=\frac{1}{2}\pi r^2 \\ =\frac{1}{2}\pi(2cm)^2 \\ =2\pi cm^2 \\ \approx6.28cm^2 \end{gathered}[/tex]Rectangle

In order to solve this equation for w, we can do the following steps:
[tex]\begin{gathered} 15w-4=41 \\ 1.\text{ Add +4 to both sides of the equation:} \\ 15w-4+4=41+4 \\ 15w=45 \\ 2.\text{ Divide both sides of the equation by 15:} \\ \frac{15w}{15}=\frac{45}{15} \\ w=3 \end{gathered}[/tex]So we have that the value of w is 3.

Since the triangle of the Image is greater than the triangle of the pre-image (original figure), then the area of the pre- image will be less than the new image
e) For two triangles to be congruent, the sides and angles for both triangles will be equal
For two triangles to be similar, the ratio of their corresponding sides will be equal
The image A'B'C' is a scaled triangle of ABC. This mean the sides can't be equal but the ratio fo their corresponding sides will be equal.

Answer:
1. P = 0.269 or 26.9%
2. P = 0.372 or 37.2%
Step-by-step explanation:
First, let's calculate the total number of students:
So, we know that the number of students is 662.
Now, let's evaluate the probabilities:
1. Student will begin college during summer AND attend an in-state college.
P = 178/662
P = 0.269 or 26.9%
2. Student will begin college in summer GIVEN THAT he is attending an in-state college.
In this case, the total number of students will be the number of students who will attend an in-state college.
P = 178/479
P = 0.372 or 37.2%

2. Write the GCF: 1
3. Rewrite expression factor out the GCF: 16y + 5
4. Write the final factored expression: 16y + 5

The initial expression is:
16y + 5

The factors of these terms are:
16y: 1, 2, 4, 16, y, 2y, 4y, 16y
5: 1, 5

Determine the initial investment, PV, for a future value of 6500 dollars if the nominal rate of interest is 5.9 percent compounded quarterly for 12 years? FV = PV(1 + r/n) ^ntPv = ________ (Be sure to give 2 decimal places of accuracy.)
Answers
Answer: PV = 3218.69
Explanation:
The formula for calculating compound interest is expressed as
FV = PV(1 + r/n) ^nt
Where
FV is the future value
PV is the initial value
r is the interest rate
n is the number of compounding periods in a year
t is the number of years
From the information given,
FV = 6500
r = 5.9% = 5.9/100 = 0.059
n = 4 because it was compounded quarterly
t = 12
By substituting these values into the formula,
6500 = PV(1 + 0.059/4)^4 * 12
6500 = PV(1.01475)^48
PV = 6500/(1.01475)^48
PV = 3218.69

A classmate claims that the function g(x)=-4ex+6 is the parent function f(x)=ex reflected across the Y axis, vertically compressed by a factor of four, translated to the left five units, and translated up six units.A) explain what the classmate described incorrectly.B) describe g(x) as a series of transformations of f(x)
Answers
Based on the function g(x), the function f(x) is multiplied by a negative number. Hence, there is a reflection across the x-axis.
If it was the "x" variable that was multiplied by a negative number for example, y = e^-x, it would have been reflection across the y-axis.
Since the number multiplied to the function f(x) is not between 0 and 1, we are stretching the function. Hence, the function is vertically stretched by a factor of 4.
Moving to the number -5 that was subtracted from the variable x, we have moved/shifted the function 5 units to the right instead of left.
Lastly, 6 was added to the entire function, therefore, we have translated the functions 6 units up.
To summarize, f(x) = e^x had undergone the following series of transformation: reflection across the x-axis, vertically stretched by a factor of 4, translated 5 units to the right, and translated 6 units up to form g(x).
