If your grade is a 93% and you got 20 points taken off your grade, what will your new grade be?

Answer: Choice A) The value of s(x) depends on the value of x, since s is a function of x.

The outer letter s tells us what the function's name is. It's the dependent variable and it might be handy to tie it to the y variable. The x is the independent variable. It changes freely without relying on what s happens to be.

Answer:  A. The value of s(x) depends on the value of x, since s is a function of x.

Step-by-step explanation: s(x) is the output of the function when a given value of x is calculated according the operations in the function.

Answer:

$40 and $72, see below :)

Step-by-step explanation:

One way we can do this is to add the total ratios and then divide that from 112.

10x + 18x = 28x = 112

28x = 112

x = 4

That means, for every ratio, you just have to multiply the amount by 4.

so for example, 10 is just 10 * 4 = 40

So, your answer would be you share the money into $40 and $72

Answer:

x=-3

Step-by-step explanation:

x+8=5

subtract 8 from 5 to get x on its own

x=-3

Answer:

y=36

Step-by-step explanation:

using that 63° angle there on the right, we know that the other angle for a 180° total is 117°.

Now we have to figure out y using that total of 117

(4y-27)=117

4y-27=117

4y=144

y=36

Now if we substitute y...

(4y-27)=117

(4(36)-27)=117

(144-27)=117

(117)=117

Answer:

a)

x      -3         -2         -1         0          1            2         3

y       0          8          6         0         -4           0        18

b)

see in the table, at x = {-3; 0; 2}, y = 0

=> x = {-3; 0; 2} is the solutions of the equation x³ + x² - 6x = 0

Step-by-step explanation:

a) 0 and 6  will be written in the given blank spaces.

b) The value of x for the given equation is 0, -3 and 2.

It is a method for finding the values of variable, by substituting the value of one variable to get the another.

To solve a polynomial equation, first write it in standard form. Once it is equal to zero, factor it and then set each variable factor equal to zero.

a). We have, an equation

[tex]y = x^{3}+x^{2} -6x[/tex]

so, at x = -3

[tex]y = -3^{3} +(-3)^{2} -6(-3)[/tex] =  -27+9+18 = 0   (substitute x = -3 in the given equation)

at x = -1

y = [tex]-1^{3} +(-1)^{2} -6(-1) = -1+1+6 = 6[/tex]

Hence, 0 and 6 will we written the blank spaces of the given table.

b). We have an equation

[tex]x^{3} +x^{2}-6x = 0[/tex]

⇒ [tex]x(x^{2} +x-6)=0[/tex]

⇒ [tex]x (x^{2} +3x-2x-6)=0[/tex]

⇒ [tex]x(x(x+3)-2(x+3))=0[/tex]

⇒ [tex]x(x+3)(x-2)=0[/tex]

⇒ [tex]x = 0,-3 and 2[/tex]

Hence, 0, -3 and 2 are the solutions of the given equation.

Answer:

a) (i) 1200

b) (ii) 3750

c) (i) [tex]\frac{3}{20}[/tex]

Step-by-step explanation:

a) Total number of students = 5000

Ratio of teachers to students = 6 : 25

i) Number of teachers = ?

By the given ratio, we can let the number of teachers = 6[tex]x[/tex]

and we can let the number of students = 25[tex]x[/tex]

[tex]25x = 5000\\\Rightarrow x = 200[/tex]

Therefore, number of teachers = 6 [tex]\times[/tex] 200 = 1200

b) A Quarter of the students own i-phone classic 20.

ii) Number of students who do not own an i-phone classic?

As per question statement,

Number of students who own i-phone classic 20 = [tex]\frac{1}{4}\times 5000[/tex] = 1250

Number of students who do not own i-phone classic 20 = 5000 - 1250 = 3750

c) Number of students who own samsung galaxy a80s = 60% of students who own i-phone classic 20 = [tex]\frac{60}{100}\times 1250[/tex] = 750

Fraction of students who own samsung galaxy a80s = Number of students having samsung a80s divided by total number of students

[tex]\dfrac{750}{5000} = \dfrac{3}{20}[/tex]

Answer:

A. The slope is  [tex]\frac{3}{2}[/tex]

B.  the slope of the tangent line at x = 1 is also the instantaneous rate of change at that point.

Step-by-step explanation:

PART A: Slope

Given tangent line;

[tex]y = \frac{3x}{2} + \frac{9}{2}[/tex]

The slope of the tangent line is equal to the derivative of the function;

[tex]\frac{dy}{dx} =\frac{3}{2}[/tex]

the slope = [tex]\frac{3}{2}[/tex]

PART B: Correct statement that describe the slope of a tangent line:

A secant line is a straight line joining two points on a function and the slope of the function is equal to average rate of change of the function between the two points.

A tangent line is a straight line that touches a function at only one point, and the slope of the function is equal to the instantaneous rate of change of the function at that one point.

Thus, the correct statement is " the slope of the tangent line at x = 1 is also the instantaneous rate of change at that point".
