Answers

Answer:

Step-by-step explanation:

Consecutive differences in Table A are constant (9−6=12−9=15−12=3), indicating a linear function. Consecutive quotients in Table B are constant (147=2814=5628=2) indicating an exponential function. Similarly the constant quotient for Table D is 1/2. Neither consecutive differences nor quotients are constant in Table C, and its ordered pairs are related by the equation y=x2+5. So, Table A should be labeled "linear", Table B and D, "exponential", and Table C, "quadratic".


2. What is a line of symmetry?
(1 Point)

Answers

Answer:

Step-by-step explanation:

I believe you're refering to an "axis of symmetry."  This is most often seen in quadratic equations.  If the parabolic graph opens up or down, the axis of symmetry is the vertical line passing through the vertex, and the graph is symmetrical about this axis.  The same applies to a parabolic graph that opens left or right.

If y = ax^2 + bx + c, the equation of the axis of symmetry is x = -b / (2a).

Will mark brainliest

Answers

Answer:

D)

Step-by-step explanation:

x² + 3x + (3/2)² = 6 - 8 + (3/2)²

(x + 3/2)² = -2 + 9/4

(x + 3/2)² = -8/4 + 9/4

(x + 3/2)² = 1/4

Answer:

D is the answer

Step-by-step explanation:

x² + 3x + (3/2)² = 6 - 8 + (3/2)²

(x + 3/2)² = -2 + 9/4

(x + 3/2)² = -8/4 + 9/4

(x + 3/2)² = 1/4

A rectangular flower bed has a width of (2x+5) and a length of (x+10). Find the area of the flower bed when the length is 25 ft

Answers

Answer:

875 ft

Step-by-step explanation:

Length is 25 feet so we can solve x with the equation x+10=25 so x=15

We can plug in 15 to find out the width. 2(15)+5=w, so w(width) is 35.

Area is length x width, length=25 and width=35 so 35 x 25= 875

875 ft

What is the equation of a circle with a radius of 6 and a center at ( -2 , 3 )?

Answers

The formula for a circle is:

(x-p)^2+(y-q)^2=r^2

The radius is given (r=6), as well as the centre of the circle (-2;3).

"p" and "q" represent the coordinates of the centre of the circle.

So it would look like this -

(x-p)^2+(y-q)^2=r^2

p=x-coordinate (-2)
q=y-coordinate (3)
r=6

(x-(-2))^2+(y-(3))^2 =6^2
(x+2)^2 + (y-3)^2 = 36

***"^" means "to the power of"

Hope this helped~

Answer:

Solution given:

centre(h,k)=(-2,3)

radius(r)=6 units

we have

equation of a circle is:

(x-h)²+(y-k)²=r²

(x+2)²+(y-3)²=6²

(x+2)²+(y-3)²=36 is required equation of a circle.

find the radius of the circle with center (2,2) that passes through (-9,-4)

Answers

Answer:

√157 units or about 12.53 units

Step-by-step explanation:

Equation of circle: (x-h)²+(y-k)²=r²

Center: (h,k) -> (2,2)

Equation so far: (x-2)²+(y-k)²=r²

Plug in (-9,-4) to find r: (-9-2)²+(-4-2)²=r² -> 121+36=r² -> 157=r² -> √157=r

Therefore, the radius of the circle is √157 units or about 12.53 units

Which could be the first step in solving this system of equations by substitution?

y = 7x

y - x = 15

Answers

Answer:

The first step is to replace the y in y-x=15 with 7x (we can do this because the first equation tells us that they're equal)

solve and get

(2.5,17.5)

or x= 2.5 y=17.5

Step-by-step explanation:

The first step is to recognize that y=7x which means that we can just replace the y in the second equation with 7x

7x-x=15

6x=15

x=2.5

Then we can solve for y

y=7(2.5)

y=17.5
