PLEASE HELP ME!!!Will mark brainlyist if right!!!

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).

I think it 10

Hope that helps

The answer for this question is 40

Answer:

Answer:

20:18 30:27 40:36 etc..

Step-by-step explanation:

To find equivalent ratios you multiply both 10 and 9 by the same number to find equivalent ratios.

Answer:

2.5 hours

Step-by-step explanation:

4 - 1.5 = 2.5

You must subtract 1.5 from the amount of hours he plays piano, which is 4. This is because he spends 1.5 hours less playing drums than he does playing piano.

Answer:

-43

Step-by-step explanation:

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".

Answer:

n=-20

Step-by-step explanation:

Answer:

n = -20

Step-by-step explanation:

n/-4 = 5

n/-4 (-4) = 5(-4)

n = -20

-20/-4 = 5

Step-by-step explanation:

The above sentence contains 30 letters, including 3 "e"s, so the frequency of e is 3/30 = 0.1 = 10%

Answer:

≈ 268 or 85.3π

Step-by-step explanation:

V = 1/3πr²h

V = 1/3 x 3.14 x 4² x 16

V ≈ 267.9467 or 268

also can be considered 85.3π

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

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

Answer:

y= -2x+ 5

Step-by-step explanation:

parallel with y= -2x+ 1 means the lines have the same slope m= -2

from point (-1, 7) we go with a slope of -2 until we find the y-intercept (0, 5)

y= mx+b is the general formula

y= -2x+ 5

Answer:

Height = 2 yards

Longer base = 8 yards

Step-by-step explanation:

From the figure attached :

The length of the shorter base of the Trapezoid = 4 yards

Hence, if height of Trapezoid is half the length of the shorter base ;

Then ;

Height of Trapezoid = shorter base/2 = 4 /2 = 2 yards

Longer base is twice the length of shorter base :

Longer base = 2 * shorter base = 2 * 4 = 8 yards

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

Hope this helps you ;)

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.
