Can someone please tell me the answers but also explain how to do it? Thank you

Answer:

26

Step-by-step explanation:

f(x) = -9x + 8

f(-2)

______________

When we have a function f(x), x can be plugged in with anything, when plugged, the equation the function f(x) is tied too will also have x replaced with the value.

Therefore, if f(x) equals f(-2), -9(-2) + 8

Multiply :

-9(-2) + 8

18 + 8

Answer:

18.84

Step-by-step explanation:

Since the radius is 3 mili then we have to multiply 3 by 2 to get the diameter. Then multiple the diameter and pie 6×3.14 is 18.84.

answer is B. varna because it is a religious chant ok f India from the Vedas in ancient cultures of Hinduism

Answer:

the area of the shape is 7.14

Step-by-step explanation:

First, find the area of the square:

2 in x 2 in = 4 in

then to find the area of the semi- circles add them together to make a circle

To find the area of the circle, use:

pi x radius^2  

Since the diameter is 2 divide the diameter by 2 to get radius  

3.14 x 1^2 = 3.14

The circle is 3.14 plus 4 ( the square ) = 7.14

Actually Welcome to the Concept of the linear equations.

so we solve here as,

==> -4(-2y+3)=20

==> 8y -12 = 20

==> 8y = 20+12

==> 8y = 32

==> y = 4

hence value of y = 4 .

Answer:

c // 20 inch

Step-by-step explanation:

edg 2021 ^u^

The diameter of the cushion is 20 inch, the correct option is C.

The standard equation of a circle is given by

(x -h)² + (y-k)² = r²

The equation is x² +y² = 100

When this equation is compared to the standard equation

r² = 100

r = 10 inch

Diameter = 2 * radius

Diameter = 2 * 10

Diameter = 20 inch

Answer:

It's answer C, as in the numbers below goes below the dividing point

The minimum number of degrees in the rotation such that the hexagon will coincide with itself is 60°

Hexagons are six-sided polygons in geometry. A hexagon is said to be a regular hexagon if all of its sides and angles have identical lengths. To put it another way, a regular hexagon's sides are congruent.

Given that, Around its center, a regular hexagon is rotated counterclockwise.

We are aware that a hexagon has six sides.

There are also 360 degrees.

According to the data given, the calculation is as follows:

= 360 /60

= 60 degrees.

Therefore, we may say that the rotation must be at least 60 degrees in total.

Step-by-step explanation:

Question 1 (answer is C)

6 4

5 2

y=mx+b

4= 6m+b

2=5m +b

by subtracting the two equations

m= 2

4= 6(2)+b

b= 4-12

b= -8

y= 2x- 8

then the answer is C

Question 2

the answer is C

the answer is Cbecause the linear function has a power of (1)

Question 3(B)

m= -2

3 5

y=mx+b

5= 3(-2)+b

Answer:

95

Step-by-step explanation:

12th square number

= 12 × 12

= 144

7th square number

= 7 × 7

= 49

Difference between the 12th square number and the

7th square number

= 12th square number - 7th square number

= 144 - 49

= 95

Difference between the 12th square number and the

7th square number = 95

Answer:

f (8) = ( -161 )

Step-by-step explanation:

[tex]f(x)=-3x^{2} +3x+7[/tex]

To find f(8) sub 8 for x in the equation and simplify:

[tex]f(8)=-3(8^{2} )+3(8)+7[/tex]

= -192 + 24 + 7

= -168 + 7

= -161

so f(8) = -161

Answer:

The simplyfied version would be 19/4

Show of work:

(1/4)^-2 = 4^2

3 × 8^2/3 × 1 = 12
