The graph of $y = f(x)$ is symmetric across the line $x = 5$. The graph also passes through the point $(8,-7).$ Find another point that must lie on the graph of $y = f(x).$
Because we know one point and an axis of symmetry, we know that the point (2, -7) must lie on the graph.
Which other point must lie on the graph?If a function has a line of symmetry at x = x₀, then we know that:
f(x₀ + x) = f(x₀ - x).
So we have symmetry around that line.
Then, if the line of symmetry is at x = 5 and we know that:
f(8) = f(5 + 3) = -7
We also must have:
f(2) = f(5 - 3) = -7
Then the point (2, - 7) must be on the graph.

How do I prove if EFGH is a rhombus in this paragraph proof?
Explanation:
There are many approaches you can take. Perhaps one of the easiest is to show the sides of the rhombus are all the same length. This can be done several ways. Here are a couple of them.
__
1.A square has degree 4 rotational symmetry, so will map to itself when rotated by any multiple of 90°. This means the midpoints of adjacent sides will map to themselves, and any segment joining the midpoints of adjacent sides will map to itself. When segments map to themselves, they are congruent, hence the four sides of EFGH are congruent, and the figure is a rhombus.
__
2.The sides of a square are the same length and all corner angles are right angles. Midpoints of the sides divide the sides into congruent parts, so all of the segments PF, FQ, QG, GR, and so on are congruent. This means all of the triangles PFE, QGF, RHG, and SEH are congruent by the LL postulate. Corresponding sides of congruent triangles are congruent, so the sides of EFGH are congruent, and the figure is a rhombus.

PLS HELP ME FRENDS I NEED HELP HELP THIS IS MY LAST CHANCE What is the area of the real object that the scale drawing models?
Answer:
D. 16 square cm
Step-by-step explanation:
To solve this problem, we will have to look at the Scale factor.
1 : 8 = 1 cm (in the scale drawing) = 8cm (in the real object)
Since the area of the scale drawing is 2 cm, the equation will be 2 x 8 = 16.
Therefore, 16 will be the area of the real object.

A baker makes 75 muffins and
puts them in boxes of 4. He fills
as many boxes as he can. How
many boxes does he need to
hold all the muffins
Answer:
19 boxes, but only 18 of them will be completely full
Step-by-step explanation:
Divide 75 by 4 to see how many boxes you can completely fill. You get 18 and 3/4, so there will be 18 boxes of four muffins (completely full), and one box with 3 muffins in it.

A teacher puts five packages of craft paper into a cabinet each package has 80 sheets of paper what is the total number of sheets of craft paper that the teacher put into the cabinet and wears a.40 b.85 c.400 d.450
Answer:
C
Step-by-step explanation:
If we have 5 packages and each contains 80, we are basically doing 80+80+80+80+80 (5 TIMES) which is referred to as 80×5=400
Answer:
1 package contain 80 sheets of paper.
If there is 5 packages, there will be 'x' sheets of paper.
We replace the sheets of paper with 'x', because the value of x is unknown.
Now we set up the equation:
Sheets 80 x__________ _________ = _________, solve for x;
Packages 1 580/1 = x/5
*5 *5
400 = x

Angle α is drawn on the unit circle in standard position. The terminal side of angle α intersects the unit circle at point (-0.292, 0.956). What is the approximate decimal value of tan(α)?
The approximate decimal value of tan(α) is -3.274, α intersects the unit circle at point (-0.292, 0.956)
What is a unit circle?
A circle is the locus of a point such that its distance from a fixed point (center) is always constant.
A unit circle is a circle with a unit radius.
Given that:
The terminal side of angle α intersects the unit circle at point (-0.292, 0.956).
Hence:
tan(α) = (0.956 / -0.292) = -3.274
The approximate decimal value of tan(α) is -3.274, α intersects the unit circle at point (-0.292, 0.956)

Ron and harry have ages that are consecutive odd integers. The product of their ages is 783. Which equation could be used to find ron’s age, r, if he is the younger man?
Answer:
The answer is (3).
Step-by-step explanation:
Ron and Harry have ages that are consecutive odd integers. The product of their ages is 783. So, the ron's age r is 27.
What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
Ron and harry have ages that are consecutive odd integers. The product of their ages is 783.
r is younger
r + 2 = s
product is 783
783 = rs
s = r +2
783 = r(r+2)
So, the quadratic equation form
783 = r^2 + 2r
0 = r^2 + 2r -783
0 = (r -27)(r +29)
set to zero
r-27 = 0
r = 27
and
r + 29 = 0
r = -29
thus, The age of ron is 27 years old.
