is .8x+1.5y=-6 a linear function?
Answers
Answer:
Yes, it is a linear function
Step-by-step explanation:
The given equation, .8x + 1.5y = -6, is a linear function.
It is in the format of the linear equation Ax + By = C.
In this equation, 0.8 is A, 1.5 is B, and -6 is C.
So, it is a linear function.
Answer:
yes
Step-by-step explanation:
[tex]0.8 x= 1.5y = -6\\0.8x + 6 = 1.5y\\\frac{0.8}{1.5}x + \frac{6}{1.5} = y\\\\y = \frac{8}{15}x + \frac{60}{15}\\\\y = \frac{8}{15}x + 4[/tex]
Therefore y is an equation of a line with slope 8/15 and y - intercept = 4

Esther is getting balloons for her father's birthday party. She wants each balloon string to be 6 feet long. At the party store, string is sold by the yard. If Esther wants to get 65 balloons, how many yards of string will she need? 1 foot = 1 3 yard
Answers
Answer: She needs 130 of string .
Step-by-step explanation:
Given: Length of each ballon string = 6 feet
Total number of ballons = 65
Total string required = ( Length of each ballon string) x (Total number of ballons)
= 6 x 65
= 390 feet
Since 1 foot = [tex]\frac 13[/tex] yard
So, [tex]390\ feet = 390\times\frac13\ yards[/tex]
= 130 yards
Hence, She needs 130 of string .

Answer:
$0.20
Step-by-step explanation:
We need to find the unit rate in order to find the price of 1 pencil.
Divide the price by the amount.
7/35=1/5
A dollar is 100 cents, so the price is 1/5 of 100, or 20 cents.

Calculate the volume of the cylinder
Answers
Answer:
4^4 = 16 (we square our radius when finding area)
16 x 3.14(we then multiply the squared radius with pi so we could get the complete area) = 50.24
Now we multiply the area of one circle by the height to get the PRISM'S volume.
50.24(area) x 13(height) = 653.12 cm^3 is your answer.

At the end of each week, an employer gives some vacation hours to a few randomly selected employees. There are 25 employees in her department—11 males and 14 females. The employer wants to know how many ways there are to give vacation hours to 6 of the employees. How many possible groups of 6 employees can the employer choose?
Answers
Answer: There are 177100 possible groups.
Step-by-step explanation:
Given: Total employees = 25
Number of employees wants to choose = 6
The combination of n things taken r at a time is given by:-
[tex]^nC_r=\frac{n!}{r!(n-r)!}[/tex]
Put n = 25 and r= 6, we get
[tex]^{25}C_6=\frac{25!}{6!(25-6)!}\\\\=\frac{25\times24\times23\times22\times21\times20\times19!}{6!19!}\\\\=177100[/tex]
Hence, there are 177100 possible groups.

The prime cost of an article was four times the value of material used. The cost of raw materials was increased in the ratio 3 : 4 and the productive wage was decreased in the ratio 4 : 5. Find the present prime cost of an article, which could formerly be made for Rs. 540
Answers
Answer:
Step-by-step explanation:
The prime cost = 4 times the value of material used
Former Prime cost = 540
Value of material = 540 / 4 = Rs. 135
Since ;
Prime cost = raw material + wages
540 = 135 + wages
Wages = 540 - 135
Wages = 405
Increase in raw material ; 3 : 4
New cost of raw materials = (4/3) * 135 = 180
Decrease in wage ; 4 : 5
New wage = 4/5 * 405 = 324
New prime cost :
180 + 324
= 504
Cherry pies cost $12 each. Apple pies cost $9 each. You sold 20 pies and brought in $198. How many apple pies did you sell? How many cherry pies did you sell?
Answers
Answer:
You sold 6 cherry pies and 14 apple pies.
Step-by-step explanation:
It's a system of equations problem.
12C + 9A = 198
A + C = 20
A = 20 - C
12C + 9(20 - C) = 198
12C + 180 - 9C = 198
3C + 180 = 198
3C = 18
C = 6
A + 6 = 20
A = 14
Answer:
Cherry Pie=$12 per 1
Apple pie= $9 per 1
Let x represent number of Cherry Pies sold.
let y represent number of Apple pie sold
x + y = 20---------------1
12x + 9y = 198---------2
From eqn 1
x=20-y
Substitute into eqn 2
12x + 9y = 198
12(20-y) + 9y=198
240 - 12y + 9y = 198
240 - 3y =198
3y = 240 - 198
3y=42
y=14.
x + y =20
x + 14=20
x=20-14
x=6.
So...
Its means that I SOLD 6 CHERRY PIES AND 14 APPLE PIES
Miguel bikes 23 km per hour and starts at mile 10. Gabby bikes 28 km per hour and starts at hour 0. Which system of linear equations represents this situation
Answers
Answer:
Miguel: d = 23t + 10
Gabby: d = 28t
Step-by-step explanation:
We can write the equation for each case in slope-intercept form, d = mt + b
Where,
d = total distance
t = time
m (rate) = distance/hr
b = initial value
✔️ Miguel:
m = 23 km/hr
b = 10 mile
Equation: subtitle the values into d = mt + b
d = 23t + 10
✔️ Gabby:
m = 28 km/hr
b = 0 mile
Equation: subtitle the values into d = mt + b
d = 28t + 0
d = 28t

Answers
Step-by-step explanation:
(B) L = 182.9 cm +- 0.1 cm
W = 152.4 cm +- 0.1 cm
(C)
Smallest dimensions possible:
L = 182.9 cm - 0.1 cm = 182.8 cm
W = 152.4 cm - 0.1 cm = 152.3 cm
A = (182.9 cm)(152.3 cm)
= 27840.44 cm^2
To find the uncertainty for the area ∆A, we use the formula
[tex] \frac{da}{a} = \frac{dl}{l} + \frac{dw}{w} [/tex]
where da = ∆A, dl = ∆L, dw = ∆W
[tex] \frac{da}{27840.44 {cm}^{2} } = \frac{0.1cm}{182.8cm} + \frac{0.1cm}{152.3cm} [/tex]
[tex] = 0.000547 + 0.000657[/tex]
[tex] = 0.001204[/tex]
Therefore
∆A = 0.001204 × 27840.44 cm^2
= 33.52 cm^2
Rounding off the numbers to their significant figures,
A = 27840 cm^2 +- 33 cm^2
(D)
For the largest possible area,
L = 183.0 cm
W = 152.5 cm
A = 27905.5 cn^2
[tex] \frac{da}{27907.5 {cm}^{2} } = \frac{0.1cm}{183.0cm} + \frac{0.1cm}{152.5cm} [/tex]
[tex] = 0.001202[/tex]
∆A = 0.001202 × 27907.5 cm^2
= 33.55 cm^2
Therefore, the largest possible area is
A = 27910 cm^2 +- 33 cm^2
