The axis of symmetry can be calculated using this formula: x = ------
2a
-(-12)
which in this case is x = ---------- = 1. The axis of symmetry is the vertical
2(6) line x = +1
Thus, x = 1 is the x-coordinate of the vertex. Normally we'd find the y-coordinate by evaluating the function at x = 1. Unfortunately your
6x²-12x-25=-7 does not have the form of a quadratic function; such a function does not have the " = " sign in it.
Example: Suppose we have 6x²-12x-25 = f(x) and we evaluate this function at x = 1: f(1) = 6(1)^2 - 12(1) - 25 = -31, which (in this example)
leads to the vertex (1, -31).

Step-by-step explanation:
is this table proportional?
explain
Answer:
yes because the hours to distance is moving at a constant rate and if you were to graph it, it would also go through the origin
Step-by-step explanation:
Answer:
No.
Step-by-step explanation:
This table is not proportional because the outputs do not get their answer using the same equation. The first to inputs and outputs ([tex]\frac{1}{2}[/tex] and [tex]\frac{1}{4}[/tex]; 1 and [tex]\frac{1}{2}[/tex]) are proportional. You multiply the input (distance) by [tex]\frac{1}{2}[/tex] to get the output (hours). The final option of input and output ([tex]2\frac{1}{2}[/tex] and [tex]1\frac{1}{4}[/tex]) is not proportional.

6x - 8y = 12 and 5x + 8y = -1 Solve using elimination
Answer:
Step-by-step explanation:
6x-8y=12
5x+8y=-1
add them
11x=11
x=1
y=-3/4
Answer:
(1,-3/4)
Step-by-step explanation:
Luckily, y is already opposites, so it should be easier:
6x-8y=12
5x+8y=-1
Combine; This should end up with y eliminated -
11x = 11
x = 1
Now we can plug 1 in for x in one of the equations to find y. I'm going to use the second one.
5(1) +8y = -1
5+8y=-1
8y=-6
y=-6/8 (you can simplify)
The point at which the lines intersect is (1,-3/4)
there were 62 people in the movie theater for the matinee. ticket sales for that showing were $364. if adult tickets cost $7 and children tickets cost $3.50, how many of each were at that show. please solve with systems of equations.
Answer:
Step-by-step explanation:
a+c=62, c=62-a
7a+3.5c=364, using c found above gives you
7a+3.5(62-a)=364 expand left side
7a+217-3.5a=364 group like terms on left side
3.5a+217=364 subtract 217 from both sides
3.5a=147 divide both sides by 3.5
a=42, since c=62-a
c=62-42=20
So 20 children and 42 adult tickets were sold.

Answer:
[tex]x=4[/tex]
Step-by-step explanation:
By the Triangle Proportionality Theorem:
[tex]\displaystyle \frac{x}{12}=\frac{x+1}{15}[/tex]
By cross-multiplication:
[tex]\displaystyle 12(x+1)=15(x)[/tex]
Distribute:
[tex]12x+12=15x[/tex]
Subtract 12x from both sides:
[tex]12=3x[/tex]
Hence:
[tex]x=4[/tex]
Answer:
4
Step-by-step explanation:
The first thing you should notice is that the triangles (the smaller one and the larger one) are similar due to angle-angle similarity (the top angle equals itself, and because the bases are parallel lines cut by a transversal, the base angle of the bigger triangle is equal to the corresponding base of the smaller triangle.
Similar triangles' corresponding sides have equal ratios to one another. That means we can set up an equation: side of smaller triangle ÷ corresponding side of larger triangle = other side of smaller triangle ÷ corresponding side of larger triangle. We plug the values given to us and can change this equation to:[tex]\frac{x}{x + 12} = \frac{x + 1}{x + 16}[/tex] **
We now multiply both sides of the above equation by [tex](x + 12)(x + 16)[/tex] to get: [tex]x(x + 16) = (x + 1)(x + 12)[/tex]
[tex]x^{2} + 16x = x^{2} + 13x + 12[/tex]
[tex]3x = 12[/tex]
[tex]x = 4[/tex]
That means our answer, for the value of x, is 4
** Make sure you don't say [tex]\frac{x}{12} = \frac{x + 1}{15}[/tex], because those aren't the sides of the larger square.

The constant rate of change is 3
Step-by-step explanation:
Given
x y
2 6
4 12
6 18
8 24
Required
Determine the constant rate of change
Represent the constant rate of change with k.
k is calculated using:
[tex]k = \frac{y}{x}[/tex]
When y = 24; x = 8
So, we have:
[tex]k = \frac{24}{8}[/tex]
[tex]k = 3[/tex]
Bonnie is n years old.
Clara is three times as old as Bonnie.
Danesh is seven years older than Bonnie.
The total of Bonnie's age, Clara's age and Danesh's age is T years.
Find a formula for T in terms of n.
Answer:
T = 5n + 7
Step-by-step explanation:
Bonnie : n
Clara : 3n
Danesh : 7 + n
T = n + 3n + 7 + n
T = 5n + 7

50 points!! I will mark brainliest to the correct answer :) please don’t put random answers... they will be reported. Thanks!
Step-by-step explanation:
Answer for the first question.
since the triangles are congruent so angles and sides are also congruent I.e. sides and angles are equal then,
3x - 3 = 12
3x = 12 + 3
3x = 15
x = 5
55° = 7x + y
55° = 7 * 5 + y
35° + y = 55°
y = 55° - 35°
y = 20°
Answer for the second question,
x + 70° = 2x - 2° {Exterior angle of a triangle is equal to the sum of two opposite interior angles }
2x - x = 70° + 2°
x = 72°
Now
<WXY = 2x - 2°
= 2 * 72° - 2
= 142 °

Answer:
the third one
Step-by-step explanation:
Answer:
[tex]\boxed {\boxed {\sf 2. \ y= -2x+17}}[/tex]
Step-by-step explanation:
We are given a point and a slope, so we can use the point-slope formula.
[tex]y-y_1=m(x-x_1)[/tex]
where m is the slope and (x₁, y₁) is a point the line passes through.
For this problem, the slope is -2 and the point is (5,7). Therefore:
[tex]m= -2 \\x_1= 5\\y_1= 7[/tex]
Substitute the values into the formula.
[tex]y-7= -2(x-5)[/tex]
We want to solve for y, because the standard form of a line is y=mx+b (where m is the slope and b is the y-intercept).
Distribute the -2.
[tex]y-7= (-2*x ) + (-2*-5)[/tex]
[tex]y-7= -2x+10[/tex]
7 is being subtracted from y. The inverse of subtraction is addition, so add 7 to both sides.
[tex]y-7+7=-2x+10+7\\y= -2x+17[/tex]
The equation of the line is y= -2x+17
