Emmanuel is starting a cycling training program. He will start cycling a short distance and increase his distance over time. Emmanuel will cycle 5 miles during the first week and increase his distance by 2 miles each week for 12 weeks.
Answers
Answer:
29milesStep-by-step explanation:
We can use the equation of a straight line as a concept to solve this problem
that is y=mx+c
at the end of the 12 weeks we can estimate the total distance that Emmanuel must have covered.
Given data.
the total distance is y
the number of weeks is x
and the starting distance is c (based on the equation of line)
starting distance= 5 miles,
increment = 2miles each week
number of weeks =12
substituting we have
y=2(12)+5
y=24+5
y=29miles
the total distance covered after 12 weeks is 29miles

The mapping does not represent y as a function of x, because 1 x-value is related to 2 y-values.
The mapping does not represent y as a function of x, because there are more x-values than related y-values.
The mapping represents y as a function of x, because each x-value is related to exactly one y-value.

D. Step 4: -8x=2x
E. Step 5: -4=x
Also explain why answer B is wrong. <3
Answers
Answer:
C. Step 3: 2x + 18 = 4x + 26
Step-by-step explanation:
Step 1: Write equation
2(x + 9) = 4(x + 7) + 2
Step 2: Solve for x
Distribute: 2x + 18 = 4x + 28 + 2Combine like terms: 2x + 18 = 4x + 30Here we see that Emily made a mistake here. Instead of adding 2 to 28 and getting 30, Emily subtracted 2 from 28 to get 26. Hence, our answer should be C.

Ivan works as a tutor for $8 an hour and as a waiter for $7 an hour. This month, he worked a combined total of 89 hours at his two jobs. Let t be the number of hours Ivan worked as a tutor this month. Write an expression for the combined total dollar amount he earned this month.
Answers
Answer:
t+623
Step-by-step explanation:
If t is the number of hours Ivan worked as a tutor this month, you can say that the number of hours that Ivan worked as a waiter would be the result of subtracting the amount of hours he worked as a tutor this month from the combined total of hours he worked, which is:
89-t
After this, you can say that the combined total dollar amount Ivan earned this month is the result of adding up what he earned as a tutor plus the amount he earned as a waiter which is equal to 89-t. So, you would have:
8t+7*(89-t)
=8t+623-7t
=t+623
This means that the expression for the combined total dollar amount he earned this month is: t+623

Answers
Answer:
a) -60
b) -450
c) Esta es una secuencia aritmética
La fórmula se da como:
an = a1 + (n -1) d
Donde a1 = primer término
d = diferencia común
n = enésimo término
d) -1584
Step-by-step explanation:
De la secuencia: -3, -6, -9, -12, -15, ...
Esta es una secuencia aritmética
La fórmula se da como:
an = a1 + (n -1) d
Donde a1 = primer término
d = diferencia común
La diferencia común para la secuencia anterior es:
Segundo término - Primer término
= -6 - (-3)
= -6 +3
= -3
Primer término = -3
a) ¿Cuál es el número que se encuentra en la posición 20?
Se nos pide que encontremos el término 20
a20 = -3 + (20 - 1) -3
= -3 + (19) -3
= -3 -57
= -60
b) ¿Cuál es el número que se encuentra en la posición 150?
Debemos encontrar el término 50
= a150 = -3 + (150 - 1) -3
= -3 + (149) -3
= -3 -447
= -450
c) ¿Cuál es la regla general de sucesión?
Esta es una secuencia aritmética
La fórmula se da como:
an = a1 + (n -1) d
Donde a1 = primer término
d = diferencia común
n = enésimo término
d) ¿Cuál es el número que se encuentra en la posición 528?
Debemos encontrar el término 528
= a528 = -3 + (528 - 1) -3
= -3 + (527) -3
= -3 - 1581
= -1584

A pool has a walkway around it that is a width of 4 1/2 feet all the way around! The length is 100 feet and the side length is 30 feet, what is the area of the walkway? Work must be shown if there is more than one answer. :)
Answers
Answer: OK two different answers.
If the dimensions of the pool are 100 × 30, and the sidewalk is outside that, the area of the sidewalk is 1251 square feet.
If the outside dimensions of the sidewalk are 100 × 30, and the pool is inside that, the area of the sidewalk is 1089 square feet.
Step-by-step explanation: Solution #1: Sidewalk outside 100×30 pool.
The sidewalk is 4 1/2 feet wide, so twice as wide all together.
The outside ends of the sidewalk are added to the pool dimensions.
100 + 9 = 109 30 + 9 = 39
The overall area: Multiply 109 × 39 = 4251 ft²
Find the area of the pool 100 × 30 = 3000 ft²
Subtract the area of the pool from the overall area 3000 - 2451 = 1251
1251 square feet is the area of this sidewalk
Solution #2: Pool inside 100×30 sidewalk.
The sidewalk is 4 1/2 ft wide so the pool will be 9 feet shorter in length and width,
100- 9 = 91 and 30 - 9 = 21 The area of this pool is 91 × 21 = 1911 ft²
The overall area is 100 × 30 = 3000 ft²
Subtract the pool's area from the overall area
3000 - 1911 = 1089
The area of this sidewalk is 1089 square feet

x = 10
x = 27
Step-by-step explanation:
53 and 5x + 3 are vertical angles.
vertical angles are equal.
using that, you can make this equation:
53 = 5x + 3
subtract 3 from both sides of the equation
53 - 3 = 5x + 3 - 3
50 = 5x
divide both sides of the equation by 5
50/5 = 5x/5
10 = x
82 and 3x + 1 are vertical angles.
vertical angles are equal.
using that, you can make this equation:
82 = 3x + 1
subtract 1 from both sides of the equation
82 - 1 = 3x
81 = 3x
divide both sides of the equation by 3
81/3 = 3x/3
27 = x

Triangle D'E'F' was formed after triangle DEF was translated 2 units to the right and 4 units up. Before the translation, what was the location of vertex E?
Answers
Answer:
The answer is below
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. Types of transformation are reflection, rotation, dilation and translation
If a point X(x, y) is translated b units up and a units right, the new location is X'(x +a, y + b).
Let us assume the coordinates of the vertex of triangle D'E'F' is at D'(-1, 5), E'(3, 2), F'(5, 8).
Since triangle DEF was translated 2 units to the right and 4 units up, the coordinate of vertex E is at E(1, -2)

Given that y is directly proportional to x.
[tex] \sf y \propto x[/tex]
[tex]\longrightarrow \sf y = k \times x[/tex]
[tex]\\[/tex]
At first, we must find the value of k.
We have a relation given between 'x' and 'y' (that is, when 'x' is 75, 'y' is 60). We can call that Case - 1.
[tex]\sf 60 = k \times 75[/tex]
[tex]\longrightarrow \sf k = \dfrac{60}{75}[/tex]
[tex]\longrightarrow \sf k = \dfrac{4}{5}[/tex]
[tex]\\[/tex]
Now, we have to find 'x' when 'y' is 480. We can call that Case - 2.
[tex]\sf y = k \times x [/tex]
We are having the value of 'y' and 'k'.
[tex]\longrightarrow \sf 480 = \dfrac{4}{5} \times x[/tex]
[tex]\longrightarrow \sf x = 480 \times \dfrac{5}{4}[/tex]
