Answer:
EZ Excavation: y = 24.5x
Happy Hauling Service: y = 25x
Step-by-step explanation:
✔️Equation for EZ Excavation:
This can be written in slope-intercept form, y = kx
Where k is the unit rate/slope/constant of proportionality
y = cost
x = dirt
Thus,
k = y/x
Using any given pair of values from the table, say, (8, 196),
k = 196/8
k = 24.5
To write the equation, substitute k = 24.5 into y = kx
Thus:
y = 24.5x
✔️Equation for Happy Hauling Service:
This can be written in slope-intercept form, y = kx
Where k is the unit rate/slope/constant of proportionality
y = cost
x = dirt
Thus,
k = y/x
Using the coordinate of any point on the line, say (1, 25),
k = 25/1
k = 25
To write the equation, substitute k = 25 into y = kx
Thus:
y = 25x

Cuánto tiempo debe transcurrir para que un capital de $3,000.00 alcance un monto de $7,000.00, si la inversión se hizo con 5% de interés simple mensual?
Answer:
27 years approx
Step-by-step explanation:
Given data
Principal P= $ 3,000
Final amount A= $ 7000
Rate r= 5%
The simple interest expression is
A=P(1+rt)
substitute and solve for t
7000=3000(1+0.05t)
7000=3000+150r
7000-3000=150r
4000=150t
t= 4000/150
t= 26.66
Hence, the time is 27 years approx

What type of real numbers are these.
Mr Jack thinks that ⅘ is equivalent to 9/10 because 4+5=9 and 5+5=10 Explain what was incorrect about this. Please use the terms numerator and denominator in your explanation, below.
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]\frac{4}{5} = \frac{9}{10}[/tex] --- Jack's thought
Because:
[tex]\frac{4+5}{5+5} = \frac{9}{10}[/tex]
Jack's thought is incorrect.
This is so because, to get an equivalent fraction; you don't add common terms to the numerator and the denominator but instead you multiply the numerator and the denominator by a common term.
Take for instance, the common term is: 2
The fraction becomes:
[tex]\frac{4 * 2}{5 * 2} = \frac{8}{10}[/tex]

Answer: 90
Step-by-step explanation:
Answer:
90m
Step-by-step explanation:
you have to cross multiply.
1) multiply (12 * 15) and multiply 2 * X)
2) you get 180 = 2x
3) to get X alone divide 180 by 2 and you will get 90meters

A hostel has food for 600
students for 50 days. After 15 days, if 180 students leave
the hostel, how long will the food last?
Answer:
Answer is 35
Step-by-step explanation:
After 15 days, 600-180=420.
After 15 days, 600-180=420.Therefore, 600 : 50
After 15 days, 600-180=420.Therefore, 600 : 50 420 : X
Let X represent the number of days.
So now, X. × 50
X. × 50 ----. ----. Or Simply 50/ 600= 1/12
X. × 50 ----. ----. Or Simply 50/ 600= 1/12 420. 600.
No u cross multiply this fraction.
Which is, X × 12= 12X
X × 12= 12X 420 × 1 = 420
U have to let X stand alone.
12X = 420
12X = 420 ------. -------
12X = 420 ------. ------- 12. 12
So now u cancel out, 12 will cancel 12 so X will stand alone.
So now 12 will cancel 420 which means 12 will go into 420, 35times.
Therefore X = 35
Meaning the hostel will feed the rest of the students for 35days.
the point-slope for mhm of a line that has a slope of -2 and passes through point (5,-2) is shown below y+2=-2(x-5)
A. y=-2x+12
B. y=-2x+8
C. y=-2x-7
D. y=-2x-3
Answer:
y = -2x + 8 (B)
Step-by-step explanation:
Just expand y + 2 = -2(x-5)
y + 2 = -2x +10
y = -2x +8 (minus both sides by 2)

Circle A is defined as (x-5)^2+(y-6)^2=16, and circle B is defined as (x+3)+(y+2)^2=9. Which transformation of circle A shows that circle B is similar?
Answer: The answer is D
Step-by-step explanation:
Circle A has translated 2 units to the right and 8 units up to produce circle B ad circle B was reduced by a factor of 3/4

Which quadratic function in vertex form has a vertex at (−5 , −4) and passes through the point (−2 , −1)?
y=−13(x+5)^2−4
y=−13(x−5)^2+4
y=13(x−5)^2−4
y=13(x+5)^2−4
Answer:
y = 1/3(x + 5)^2 - 4
Step-by-step explanation:
The general vertex form is;
y = a(x-h)^2 + k
From the question, (h,k) are the coordinates of the vertex which is (-5,-4)
So we have
y = a(x + 5)^2 -4
So we need to get the leading coefficient
Simply substitute the point it passes through
x = -2 and y = -1
-1 = a(-2 + 5)^2 - 4
-1 = a(3)^2 -4
-1 = 9a -4
9a = 4-1
9a = 3
a = 3/9
a = 1/3
So the equation is;
y = 1/3(x + 5)^2 - 4
