Answer:

21.67

Step-by-step explanation:

look at the number next to 7 to determine how it will change.

The number is 3 which is under 5 so the 7 stays the same while 3 is gotten rid of

Answer:

14 is a function, 15 is also a function

Step-by-step explanation:

You can use the vertical line test to see if a curve is a function. If the vertical line intersects the graph more tha one time, it not a fuction. If only one time, it is a function.

Answer:

14. Yes

15. No

Step-by-step explanation:

14. Passes vertical line test.

15. Does not pass vertical line test.

Answer:

X is 18 degrees

A ciricle total is 360 degrees so you add up all of the degrees that you have subtract it from 360 then divide that number by 17 to get x

9514 1404 393

Answer:

  about 2.1

Step-by-step explanation:

The slope of the secant line is given by the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (121/100 -1)/(11/10 -1) = (21/100)/(1/10) = 2.1

The slope of the tangent is about 2.1.

_____

Additional comment

We can refine our estimate by choosing a secant line between the points (9/10, 81/100) and (11/10, 121/100). That is, points either side of x=1.

That slope is ...

  (121/100 -81/100)/(11/10 -9/10) = (40/100)/(2/10) = 2.0

We expect the slope of the tangent at x=1 to be exactly 2.0.

Answer:

y=x+500

Step-by-step explanation:

y=x+500

Answer:

every pair is being multi by the next number

Step-by-step explanation:

2 x 3 =6

3 x 4 = 12 so the second number goes up one every time

Answer:  25%

Answer:

7x+80

Step-by-step explanation:

7 times everything in the () and get

56+7x+24

combine like terms

7x+80

Answer:

70+7X

Step-by-step explanation:

7(8+X+2)

7(8)+7(X)+7(2)

=56+7X+14

=70+7X

Answer:

7p+7q+63

Step-by-step explanation:

Distributive property is basically just multiplying the outside number with the things that are in the parentheses. so 7*p is 7p, 7*q is 7q, and 7*9 is 63, so that makes your answer 7p+7q+63

Answer:

D and E

Step-by-step explanation:

-5 and -6.1 are the only ones less than -4.8

Answer:

I think 3 because the it is the positive side of y

and the other should be -3 because it is the negative side

Answer:

13)  [tex]\frac{3m}{2n^2}[/tex] (answer (C))

14)  [tex]\frac{4b}{3}[/tex] (answer (A))

Step-by-step explanation:

Problem 13)

Cancel  out in PAIRS the common factors in numerator and denominator

[tex]\frac{3m^4n^2}{2m^3n^4} =\frac{3m}{2n^2}[/tex]

which agrees with answer C

Problem 14)

Cancel  out in PAIRS the common factors in numerator and denominator

[tex]\frac{4a^2b^2}{3ba^2} =\frac{4b}{3}[/tex]

which agrees with answer A

Answer:

5/16 Got a C

Step-by-step explanation:

A = 1/4 x 32

B = (32 - A)/2

D = 2

A = 8

B = (32 - 8)/2

B = 24/2

B = 12

D = 2

8 + 12 + 2 = 22

22/32 did not get a C

32/32 - 22/32 = 10/32

10/32 - > 5/16

Answer: C

Step-by-step explanation:

Standard form for multi-variable expession( quadratic, trinomial, polynomial, etc) are represented by something like this.

ax^2+ bx+c, which means the stating term is the degree or exponet  with the highest number then as we go right the degree go smaller.

So that means 5x^4 will be the starting term so a and b are ruled out. The next term will be x squared o x^2 so the only answer that has it second is C

Answer:

The answer is C

Step-by-step explanation:

The solution is, The value of x is 8. so, the correct answer is option C.) 8.

Here, we have,

from the given diagram, we get,

In the diagram, LW is parallel to ST.

RL = 6 centimeters, LS = 3 centimeters, and WT = 4 centimeters.

as, we know that,

if, LW is parallel to ST , by property of triangle,

we get,

LW divides RT & RS proportionally.

i.e. RW: WT = RL : LS

now, here, RW = x

so, we have,

x: 4 = 6 : 3

or, x = 6 *4 / 3

or, x = 8

Hence, The value of x is 8.
