a. Explain in words what is done to the input value (20) to produce the output value (y).
b. Write the rule you described in part (a) with algebraic symbols.
Answer:
(a) Rule: Multiply the input (x) by 2 and add 5 to the result of the product
(b) [tex]y =2x +5[/tex]
Step-by-step explanation:
Given
The attached table
Solving (a): The rule of the table in words
First, we calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Using:
[tex](x_1,y_1) = (2,9)[/tex]
[tex](x_1,y_1) = (10,25)[/tex]
So, we have:
[tex]m = \frac{25 - 9}{10 - 2}[/tex]
[tex]m = \frac{16}{8}[/tex]
[tex]m=2[/tex]
The equation is calculated using:
[tex]y - y_1 =m(x - x_1)[/tex]
Using:
[tex](x_1,y_1) = (6,17)[/tex]
We have:
[tex]y - 17 =2(x - 6)[/tex]
[tex]y - 17 =2x - 12[/tex]
Make y the subject
[tex]y =2x - 12+17[/tex]
[tex]y =2x +5[/tex]
Hence, the rule is:
Multiply the input (x) by 2 and add 5 to the result of the product
(b): The rule, in algebra
As solved in (a), the rule is:
[tex]y =2x +5[/tex]

Find the area of the trapezoid with bases 5cm and 2cm and height 1/5 cm.
(Simplify your answer)
Answer:
1
Step-by-step explanation:
[tex]\frac{(5 + 2) * \frac{1}{5} }{2}[/tex] = [tex]\frac{\frac{7}{5}}{2}[/tex] = [tex]\frac{1.4}{2}[/tex] = 0.7, rounded to the nearest ones is 1.
Answer:
0.7
Step-by-step explanation:
The formula for the area of a trapezoid is (A+B)÷2×H
So our formula is (5+2)÷2×1/5
1.
5+2=7
2.
7÷2=3.5
3.
3.5×1/5=0.7
That's why the answer is 0.7

Help!! Find the area of the triangle.
Answer:
Area = 60.0 units²
Step-by-step explanation:
First, let's find the height of the triangle using Pythagorean Theorem:
Height = √(11² - 8²)
= √57
Height = 7.5 (nearest tenth)
✔️Find the area:
Area = ½*base*height
Base = 2*8 = 16
Height = 7.5
Plug in the values
Area = ½*16*7.5
Area = 60.0 units² (nearest tenth)

A painter leans a ladder up against a wall. The ladder is 25 feet long and the wall is 15 feet high. How far from the wall is the base of the ladder?
Answer:
12 feet
Step-by-step explanation:
The ladder is 12 feet up the wall.
The ladder forms a right triangle with the wall and the ground. You want to use Pythagorean theorem to solve the problem. a2+b2 = c2
Use the Pythagorean Theorem (a2+b2=c2) where b=9 and c=15. Solve for a.

Answer:
h = 26cm
Step-by-step explanation:
V = (l w h)/3
so the volume of the first one is
20*12*13 /3= 1040
1040 = 12*10*h/3
3120 = 120h
h = 26
The answer is C. 23 cm

Answer: y-1=-1/2(x-5)
Step-by-step explanation:
[tex]\frac{2-1}{3-5}[/tex]
-1/2 slope
y-[tex]y_{1}[/tex]=m([tex]x-x_{1}[/tex])
y-1=-1/2(x-5)

y=-1/2x+7/2
A car travels 136 miles using 7 gallons of gas. At that rate, how far can the car travel using 42 gallons of gas?
Answer:
in 136 miles=7 gallons
?=42 gallon
= 136=7
?=42
cross multiply
136×42=5,712
=5,712÷7=816
Answer:
816 miles
Step-by-step explanation:
136miles/7 g =19.43
19.43 x 42 ≅ 816.06
or
136/7 = X/42
solve for X
42/7 =6, then 136 x6= 816
x = 816 miles

Find the greatest common factor of 7x and 4x?.
Answer:
GCF = x
Step-by-step explanation:
The factor decomposition is:
7 * x for the first term
2 * 2 * x for the second term.
The ONLY common factor is "x", and the maximum power at which it appears in BOTH terms is "1" (one)
Therefore GCF = x
