Which statements are true about the graph of the function f(x) = x2 – 8x + 5? Select three options.
The function in vertex form is f(x) = (x – 4)2 – 11.
The vertex of the function is (–8, 5).
The axis of symmetry is x = 5.
The y-intercept of the function is (0, 5).
The function crosses the x-axis twice.
The equation is f(x) = x² – 8x + 5. Then the y-intercept is at (0, 5) and the function crosses the x-axis twice. Then the correct options are A, D, and E.
What is the equation of the parabola?Let the point (h, k) be the vertex of the parabola and a be the leading coefficient.
Then the equation of the parabola will be given as,
y = a(x - h)² + k
The quadratic equation is given below.
f(x) = x² – 8x + 5
Convert the equation into vertex form, then the equation will be
f(x) = x² – 8x + 5
f(x) = x² – 8x + 16 – 16 + 5
f(x) = (x – 4)² – 16 + 5
f(x) = (x – 4)² – 11
The graph of the function is given below.
From the graph, the y-intercept is at (0, 5) and the function crosses the x-axis twice.
Then the correct options are A, D, and E.

Quadrilaterals are shapes that have a total of four sides. Rectangles, parallelograms, squares, and rhombuses all have a total of four sides. Therefore, they are quadrilaterals.
Rectangle, Parallelogram, Square and Rhombus are Quadrilaterals.
We know,
A quadrilateral is a polygon with four sides. It is a geometric shape that is characterized by having four straight sides and four vertices. The interior angles of a quadrilateral add up to 360 degrees.
As, Rectangle have four sides then it is a quadrilateral.

1. You start a biology experiment with 4,500 cells. The cells are continuously growing and 2 minutes later
there are about 22583 cells. What is the rate of growth per minute?
Answer:
80.65% per minute
Step-by-step explanation:
For continous growth :
A = Pe^rt
A = amount after time, t
P = initial amount
r = growth rate
22583 = 4500 * e^r*2
22583 = 4500 * e^2r
22583 / 4500 = e^2r
5.0184444 = e^2r
Take the In of both sides
1.61312 = 2r
r = 1.61312 ÷ 2
r = 0.80656
0.80656 * 100% = 80.65%

d is correct 180-43=137
Answer:
D) m<4 = 137
Step-by-step explanation:
m<3 + 56 = 180
m<3 = 124
m<1 + 43 + 56 = 180
m<1 + 99 = 180
m<1 = 81
m<4 + 43 = 180
m<4 = 137
m<2 + <1 = 180
m<2 + 81 = 180
m<2 = 99

Answer:
10=-2x+20
Step-by-step explanation:
Above line is incorrect. It should be 10=10x+20 . You add +6x to get 10x, not -6x.
then solve
10=10x + 20
-10=10x
-1=x
if you substitute -1 for x in the original problem, it equals:
-2(3(-1)-5)=4(-1+3)+8
-2(-8)=4(2)+8

Answer:
[tex]2x+3y\geq 60\\x>10[/tex]
Step-by-step explanation:
We know that she will be selling bracelets for $2 each and earrings for $3 each. That means we will have 2x+3y, where x is the number of bracelets she sells and y is the number of earrings she sells. Then we will have [tex]\geq 60[/tex] because she wants to sell at least $60 worth of earrings and bracelets. That means the amount she makes from bracelets and earrings combined has to equal 60 or more, thus we use the greater than or equal to sign.
Now we have [tex]x>10[/tex], where x is still the number of bracelets sold. She said she will sell more than 10, which means we will just have [tex]>10[/tex]. If she said she wanted to sell at least 10, then it would be [tex]\geq10[/tex].
Therefore the system of inequalities is:
[tex]2x+3y\geq60\\x>10[/tex]

Which diagram shows a pair of angle measure that proves lines c and d are parallel?
Answer:
C
Step-by-step explanation:
At first glance, it seems like all the answers work. But some careful thinking allows us to find the correct answer.
For this question, we will be using the process of elimination.
First, we can eliminate D, because it does not provide any angles on line d, so we cannot prove that line c is parallel to line d.
Second, we can eliminate A. It seems that the 2 angles makes it so that lines c and d must be parallel, however, that is only true if lines a and b are parallel. Since we don't know whether or not lines a and b are parallel, we cannot prove that lines c and d are parallel, so we can eliminate this choice.
Third, we can eliminate B. Like the diagram in A, this diagram can only prove lines c and d are parallel if lines a and b are parallel, and since we don't know whether or not lines a and b are parallel, we cannot prove tat lines c and d are parallel, so we can eliminate this choice.
We are left with C, so the answer must be C.
Of course, just to make sure, we will also check diagram C. Because the 2 angles provided in the diagram are on line a and none are on line b, we do not need line a to be related to line b in any way, as such we can pretend that line b does not exist in this diagram. We can then see that lines c and d must be parallel for this diagram, or else the angles would not work, so C is correct.
Two angles whose sum is 180° are called supplementary angles. The correct option is C.
What are supplementary angles?Two angles whose sum is 180° are called supplementary angles. If a straight line is intersected by a line, then there are two angles form on each of the sides of the considered straight line. Those two-two angles are two pairs of supplementary angles. That means, that if supplementary angles are aligned adjacent to each other, their exterior sides will make a straight line.
When two parallel lines are cut by a transverse. The angles formed on the exterior of the parallel lines are known as the Exterior Angle.
Now, For two lines two be parallel in the given diagram the measure of the angle the exterior angle on the same side of the transverse should be supplementary to each other.
The diagram shows a pair of angle measure that proves lines c and d are parallel in option c. This is because lines c and d are parallel and a is transversal to the two lines. And the measure of the exterior angles formed on the same side of the transversal is supplementary.
Hence, the correct option is C.

In the equation: (16)^3=2^3/2x how could you solve for x?
Answer:
x = 8
Step-by-step explanation:
16 is the same as 2^4
(2^4)³ = 2^3/2x
2^12 = 2^3/2x
as long as bases are both the same then set exponents equal
12 = [tex]\frac{3}{2}[/tex]x
3x = 24
x = 8
Anchor: If you start with 50 g of a material, how much is half of that? How much is half of half? How much is half of that?
Answer:
Step-by-step explanation:
1/2 of 50 grams is the same thing as 50 divided by 2 which is 25
Now you take 1/2 of 25 grams. That's 25 divided by 2. Use your calculator if you're not sure 25 divided by 2 = 12 and 1/2 or 12.5
I think we're down to 1/2 of 12.5
1/2 of 12.5 is 6 and then 0.5/2 which is 0.25
So 1/2 of 12.5 is 6.25
If I left one out, leave a comment.
Just in case 1/2 of 6.25 = 6/2 = 3
1/2 of 0.25 = 0.25/2 = 0.125
so the answer here is 3.125
