Step-by-step explanation:
You have done the hard part: finding the vertex.
__
The leading coefficient is the coefficient of the x^2 term. It is +1, a positive number, so the parabola <em>opens upward</em>.
__
The x-coordinate of the vertex for a parabola described by ...
f(x) = ax² +bx +c
is ...
x = -b/(2a)
For this parabola, a=1, b=6, c=2, and the x-coordinate of the vertex is ...
x = -6/(2(1)) = -3
The value of the function at that point is ...
f(-3) = (-3)² +6(-3) +2 = 9 -18 +2 = -7
The coordinates of the vertex are ...
(-3, -7)
__
The axis of symmetry is the vertical line through the vertex. Its equation will be ...
x = -3
__
Some points on the graph can be found by choosing x-values near the vertex value. They will be symmetrical about the axis of symmetry. When the leading coefficient is 1, the y-values will increase above the vertex point by the square of the x-distance from the vertex. The point at x= (-3 +2) will be at y = (-7 +(2²)), or (x, y) = (-1, -3). The symmetrical point is (-5, -3).
Answer:
ok, so 46 times 4 is 184.
Step-by-step explanation:
46
x 4
-------
184
So 6 times 4 is 24 and then you carry over the 2. 4 times 4 is 16. You add 2 to 16 and you get 18. So the total would be 184.
It's kinda hard to explain over brainly
She did sell the newspapers for $.25 each at age 80. The equation is referred to as a linear equation in one variable if only one variable is present in the linear equation.
<h3>A linear equation is what?</h3>
It is described as the relationship between two variables, and a straight line results from plotting the graph of the linear equation.
The information provided in the issue is;
One newspaper will set you back $.25.
Other newspapers are $.40 each.
The 100 newspapers were purchased for $28.00.
x is the quantity of newspapers sold for $.25 each.
Y stands for the other newspaper's number.
The total of both newspapers is one hundred.
x+y=100
y=100-x
25x+ 40y=28.00
25x+40(100-x)=2800
25x+4000-40x=2800
-15x+4000=2800
-15x=-1200
x=80
She therefore sold 80 newspapers for $.25 each.

Answer:
10
Step-by-step explanation:
If J + K = 90 degrees and K = 45 degrees, J has to be 45 degrees.

Vertical lines are perpendicular to horizontal lines.
So the equation of the line is a vertical line that pass through (3,4).
(3,4) has an x-value of 3.
So the line, x=3 will go through it.
answer: x=3
