Answer:
Rate of change = -0.2
Step-by-step explanation:
Given:
(-3, 3.6) and (5, 2)
Required:
Rate of change
Solution:
Formula for rate of change = change in y/change in x = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let,
(-3, 3.6) = (x_1, y_1)
(5, 2) = (x_2, y_2)
Plug in the values into the equation:
Rate of change = [tex] \frac{2 - 3.6}{5 -(-3)} [/tex]
Rate of change = [tex] \frac{-1.6}{8} [/tex] = -0.2

Solve the following quadratic equation for all values of x in simplest form (x+4)²+38=47
Answer:
- 1
Step-by-step explanation:
( x + 4 )² + 38 = 47
( x + 4 )² = 47 - 38
( x + 4 )² = 9
( x + 4 )² = 3²
Square root on both sides,
x + 4 = 3
x = 3 - 4
x = - 1

Find the length of the radius of the circle.
a. r = 3 d. r = 5
b. r = 4 e. r = 6
c. r = 4.5
Answer:
D) r=5
Step-by-step explanation:
Any triangle formed with one side of the triangle being the diameter of the circle it’s inscribed in will be a right triangle.
6²+8²=c²
36+64=c²
100=c²
√100=c
c=10
So the diameter is 10. That makes the radius 5.

Answer:
X=3
Step-by-step explanation:
Since all the sides of a square are equal, hence;
5x-2 = x+10
Collect like terms
5x-x = 10+2
4x =12
X = 12/4
X =3
Hence the value of x is 3

Rewrite each fraction with a denominator of 10 7/2= 3/5=
Answer:
7/2 = 35/10
3/5 = 6/10
Step-by-step explanation:
To get a common denominator of 10, simply multiply the current denominator by any number to equal 10. The first fraction has a denominator of 2. If we divide 10 by 2, we get the answer 5. This means 2 can be multiplied by 5 to get a denominator of 10. However, what we do to the denominator we must also do to the numerator (multiply by 5).

3/5 = 6/10
Step-by-step explanation:
[tex]\frac{7}{2}\cdot \frac{5}{5}=\frac{35}{10}[/tex]
[tex]\frac{3}{5}\cdot \frac{2}{2}=\frac{6}{10}[/tex]
At the math store, one circle costs one amount, and each square costs another amount. 5 circles plus one square is 20 cents. How much would 12 circles plus 5 squares cost?
Answer: 61 cents
Step-by-step explanation:
Let’s assume a circle is X and a square is Y.
The problem states:
5x + 1y = 20
2x + 3y = 21
Taking the 1st equation we can see that
1y = 20-5x which is the same as
y = 20–5x
If we replace y in the 2nd equation with the above we get:
2x + 3(20–5x) = 21
which is the same as
2x + 60 - 15x = 21
we can rearrange to get
2x -15x = 21 -60
which is the same as:
-13x = -39
therefore x = -39/-13 or
x = 3
We can then calculate y
If y = 20–5x, then y = 20 -15
There y = 5
So to answer you question, 12 circles plus 5 squares =
12x + 5y = 12(3) + 5(5) = 36 + 25 = 61 cents
hope this helps

explain how sandbars in the ocean are formed.
Answer:
Sandbars begin forming underwater. As waves break, this pulls material from the shoreline, migrating further into the ocean. During heavy storms, large waves can build sandbars far from shore, until they rise above the water's surface.
Step-by-step explanation:
Water brings sand and other sediment to the surface and creates a strip of land that lays between water.

Answer:
15: Yes, no, yes, yes, no; 16A: C = ($0.29)X + ($1.45)Y + ($2.50)Z; 16B: Yes
Step-by-step explanation:
For question 15: We need to multiply the widths and lengths given to see if they equal the area we are trying to achieve. Therefore, some of them work, and some do not.
For question 16:
Part A: We'll set a variable for the number of each supply she can buy. Pencils will be represented by X, pens by Y and Notebooks by Z, and we'll represent total cost by C. The total cost will therefore be represented by C = ($0.29)X + ($1.45)Y + ($2.50)Z.
Part B: We'll plug the numbers of items she wants to buy into our formula and see if it comes out to less than $20. So in this case C = ($0.29)(3) + ($1.45)(4) + ($2.50)(2). Therefore, C = $11.67, which is less than $20, so she can afford her school supplies.
