So the question is what does the point (-3, -5) correspond to on the graph of the function. If we have a point on a graph in the Cartesian coordinate system then that point consists of coordinates (x, y). In other words, y=f(x) and x so (x, f(x)) where x is a x-coordinate and y=f(x) is y-coordinate. So if we have a point (-3, -5) the corresponding coordinates are x=-3 and y=f(x)=-5. So it must be true that y=f(-3)=-5. So the correct answer is a. f(-3)=-5.

A group of 100 students took a quiz. Their average score was 76 points. If the average score for the boys was 80 points and the

sveta [45]

Answer:

The number of girls participated in quiz is 40 .

Step-by-step explanation:

Given as :

Total number of students took quiz = 100

Average score of 100 students = 76 points

The Average score of boys = 80 points

The Average score of girls = 70 points

Let The number of boys participated in quiz = b

Let The number of girls participate in quiz = g

Now, According to question'

Total number of students took quiz = number of boys participated in quiz + number of girls participated in quiz

Or, b + g = 100 ........A

Again

∵ Average score of 100 students = 76 points

∴ Total score of 100 students = 76 × 100 = 7600

So, Average score of boys × number of boys participated + Average score of girls × number of girls participated = Total score of 100 students

Or, b × 80 + g × 70 = 7600

Or, 80 b + 70 g = 7600 .........B

Now, Solving equation A and B

(80 b + 70 g ) - 70 ×( b + g ) = 7600 - 70 × 100

I.e (80 b - 70 b) + (70 g - 70 g) = 7600 - 7000

Or, 10 b + 0 = 600

∴ b = $\dfrac{600}{10}$

i.e b = 60

So, The number of boys participated in quiz = b = 60

Put the value of b into eq A

∵ b + g = 100

So, g = 100 - b

Or, g = 100 - 60

i.e g = 40

So, The number of girls participated in quiz = g = 40

Hence, The number of girls participated in quiz is 40 . Answer

Please can someone help me with both questions. Thank you. Work is due tomorrow.

So let's begin!
So the length is 25 and the entire perimeter is 106. Lets put these both of these numbers as information we know.

We know the length is 25.
We know the full perimeter is 106.
We also know a rectangle has 2 pairs of congruent sides.

Okay so, the length is 25.
Since there are two sides that are the same we would multiply 25 by 2 to get 50.

Now we know 2 sides out of the four sides on a rectangle.

106 is the final perimeter, if we subtract 50 from 106, we get 56. That is the measurement for both sides we're missing but we need to know the width for just one side.
So we divide 56 by 2 to get 28.
The width is 28.

Heres the show your work part:

25 x 2 = 50
Gets both lengths for rectangle.

106 - 50 = 56
Gets the product for the widths.

56 / 2 = 28
Gets the width of just one side.

Your final answer: 28

G(x) = -x^3+4 f(x)=4x-2 find (f-g) (3x)

sukhopar [10]

Answer:

(f-g) (3x)=27x^3+12+2

Step-by-step explanation:

First lets write the following:

(f-g) (3x)= f(3x)-g(3x)

Now we need to find equivalent expression for f(3x) and for g(3x), we will obtaine them by evaluating 3x instead of x in every 'x' appearance.

Wi have>

g(3x)= -27x^3+4

f(x)=12x-2

Now, lets perfomr the desired operation.

f(3x)-g(3x)=27x^3+12+2
