Answer:
CD = 48
Step-by-step explanation:
Find the value of x using the two equations
9x - 15 = 7x - 1
9(7) - 15 = 7(7) - 1
63 - 15 = 49 - 1
48 = 48
Answer: x = 7
Then get the result of both equations
CD = 48
The length of CD is 48 units.
What is Isosceles Triangle?Isosceles triangles are those triangles which has the length of two sides or angles are equal to each other.
Given triangle ABC is an isosceles triangle since the length of sides AB and BC are given to be equal.
BD is the altitude of the triangle from the vertex B.
We know that, altitude of an isosceles triangle from the non equal angle bisect the opposite side, which is base.
So, AC is bisected at D.
AD = CD
9x - 15 = 7x - 1
Solving,
9x - 7x = -1 + 15
2x = 14
x = 7
Length of CD = 7x - 1 = 49 - 1 = 48
Hence 48 units is the length of CD.

Ray is constructing a flowerbed for the zoo and wants to
know if he has enough edging. A sketch of the flowerbed
is shown below. What is the perimeter of the triangle?
Round to the nearest whole number.
72 ft
41 ft
12 ft
24 ft
12 H
48 ft
Answer:
Option (3)
Step-by-step explanation:
Since, flowerbed is in the shape of a right triangle,
By applying Pythagoras theorem in the given right triangle,
(Hypotenuse)² = (leg 1)² + (leg 2)²
(Hypotenuse)² = (12)² + (12)²
(Hypotenuse)² = 144 + 144
Hypotenuse = √288
Hypotenuse = 16.97
≈ 17 ft
Perimeter of the triangle = Sum of the measures of three sides of the triangle
= 12 + 12 + 17
= 41 ft
Therefore, Option (3) will be the correct option.
Answer:
41ft

if you do the problem 5 and 11 with that multiply and but dont forgoet to divide that number its B
the table below does not represent a function why?
Answer:
Because X (10) repeats
Step-by-step explanation:
A function has no repeated X but here in your x variable 10 is there twice so therefore it is NOT a function
You can use the pencil test also in a graph, align your pencil vertically and see if there are multiple points that have the same X and if there isn't any repeated its a function.
Answer:
The function is a relation between two sets that associates to each element of the first set exactly one element of the second set.
We have x = 10 twice with different f(x) associated, 5 and 20.
If we plot those points they will be on same vertical line, thus the vertical line test is failed.

For every person who actually has the flu, there are 6 people who have flu-like symptoms resulting from a cold. If a doctor sees 40 patients, write and solve a proportion to determine how many of these you would expect to have a cold
Answer: The number of people can be expected to have cold = 34
Step-by-step explanation:
Given: The ratio of people who actually have the flu to the people who have flu-like symptoms is 1:6.
If a doctor sees 40 patients, then the number of people can be expected to have cold = [tex]40\times\dfrac{6}{1+6}[/tex]
[tex]=40\times\dfrac6{7}[/tex]
[tex]=\dfrac{240}{7}\\\\=34.29\approx34[/tex]
Hence, the number of people can be expected to have cold = 34
Write an equation of the line that passes through (5,0) and is parallel to the line
y = -3x + 2
Answer:
y=-3x+15
is the equation that passes through the point (5,0) and is the parallel line to y=-3x+2
Step-by-step explanation:
find the slope of the original line and use the point-slope formula y-y₁=m(x-x₁) to find the parallel line of y=-3x+2, which if done correctly you should end up with y=-3x+15.

For the triangles to be congruent by HL, what must be the value of x?
2
3
4
7
We have been given two right triangles. We are asked to find the value of x, which will make both triangles similar by Hypotenuse-Leg congruence.
Hypotenuse-Leg theorem states if one leg and hypotenuse of a right triangle is congruent to the one leg and hypotenuse of other right triangle, then both triangles are congruent.
So we can set an equation as:
2x + 1= 9
Upon subtracting 1 from both sides we will get,
2x+1 -1 = 9-1
2x=8
Dividing both sides of our equation by 2 we will get,
x= 4
For the triangles to be congruent by the HL Congruence Theorem, the value of x must be: C. 4.
What is the HL Congruence Theorem?If a leg and the hypotenuse of one right triangle are congruent to a corresponding leg and the hypotenuse of another right triangles, the HL Congruence Theorem states that the triangles are congruent to each other.
Therefore, the two corresponding parts of the right triangles are given as:
2x + 19Thus:
2x + 1 = 9 (HL Congruence Theorem)
Solve for x2x = 9 - 1
2x = 8
x = 4
Therefore, for the triangles to be congruent by the HL Congruence Theorem, the value of x must be: C. 4.

2 passing through the point (-2,9).
Answer:
y = 7/2 x+16
Step-by-step explanation:
The equation for a line is y = mx+b where m is the slope and b is the y intercept
y = 7/2 x+b
Substitute the point into the equation
9 = 7/2(-2)+b
9 = -7+b
9+7 = b
16 = b
y = 7/2 x+16
