Answer:
3x -4y = 12
Step-by-step explanation:
There are a number of different forms of the equation of a line. A few are ...
y = mx + b . . . . slope-intercept form
y -k = m(x -h) . . . . point-slope form
x/a +y/b = 1 . . . . intercept form
ax +by +c = 0 . . . . general form
ax +by = c . . . . standard form
In "standard form", the coefficients a, b, c are mutually prime integers (have no common factors) and the leading coefficient (usually, 'a') is positive.
__
Given this graph, there are several ways to get to a standard form equation. Perhaps the quickest is to start with intercept form. We can see from the graph that the x-intercept is 4 and the y-intercept is -3. So, we can write the equation of the line in intercept form as ...
x/4 +y/(-3) = 1
Multiplying this by 12 clears the fractions and gives us standard form:
3x -4y = 12

PLEASE HELPPP Divide both sides by 16: 16x/16=20/16
Answer:
x = 5/4
Step-by-step explanation:
16x / 16 = 20 / 16
x = 5/4
Answer:
x = 5/4 or 1.2
Step-by-step explanation:
20/16 can be simplified to a smaller fraction, which is 5/4 because 20 and 16 have a common multiple of 4. 5/4 turned into a decimal is 1.2.
A restaurant has 9 3/5 pounds of onions. The restaurant's manager ordered 4 4/5 more pounds of onions. The onions then were mixed and kept in 2 baskets with each basket having equal pounds on onions. How many pounds of onions does each basket contain?
Answer:
7 1/5 pounds in each basket
Step-by-step explanation:
Original pounds of onion = 9 3/5
New pounds of onion = 4 4/5
The onions then were mixed and kept in 2 baskets with each basket having equal pounds on onions
Total onions = Original pounds of onion + New pounds of onion
= 9 3/5 + 4 4/5
= 48/5 + 24/5
= 48+24/5
= 72 / 5 pounds
How many pounds of onions does each basket contain?
Pounds in each basket = Total pounds /2 basket
= 72/5 ÷ 2
= 72/5 × 1/2
= 72 / 10
= 7 2/10
= 7 1/5 pounds in each basket

Tom can inflate 20 basketballs in 16 minutes . He concludes that if the total number of basketballs he can inflate, b, is proportional to the number of minutes
Answer:
Step-by-step explanation:
Step one:
given
we are told that tom can inflate 20 basketballs in 16 minutes
hence in one minute, he can inflate 20/16
= 10/8= 5/4 basketballs per minute
the rate at which he inflate the ball is 5/4 ball per minute.
The total number b is proportional to the number of minute

School fundraiser Amy sold 28 bags of popcorn and 40 candy bars and made to 282. Sarah sold 17 bags of popcorn 20 candy bars and made 160.50 the cost for a bag of popcorn in
Answer:
cost of popcorn bag is 6.5
Step-by-step explanation:
Here, we want to find the cost of a popcorn bag
let the cost of a bag of popcorn be p
let the cost of a bag of candy bar be c
Mathematically;
28p + 40c = 282
17p + 20c = 160.50
Multiply ii by 2 and subtract from i
28p + 40c = 282
34p + 40c = 321
34p-28p = 321-282
6p = 39
p = 39/6
p = 6.5

how to rewrite 3/4 with a denominator of 12
Answer:
it would be 9/12
Step-by-step explanation:
if you want to get a denominator of 12 you would have to multiply by 3 from both and you should get 9/12. 3*3=9 and 4*3=12.
Answer:
9/12
Step-by-step explanation:
4x3=12
because we are multiplying the denominator we also have to multiply the numerator by the same number

Answer:
SAS
Step-by-step explanation:
Answer:
SAS
Step-by-step explanation:
I think it is SAS because it stands for Side-Angle-Side. The segment AD is congruent to itself because of reflexive property, so now you have two sides congruent and one angle congruent.
A scientist uses a submarine to study ocean life.
• She begins at sea level, which is at an elevation of o feet
• She travels straight down for 90 seconds at a speed of
3.5 feet per second
• She then travels directly up for 30 seconds at a speed of
2.2 feet per second
After this 120 second period, how much time, in seconds, will it take for the scientist to
travel back to sea level at the submarine's maximum speed of 48 feet per second?
Round your answer to the nearest tenth of a second.
Show your work
Answer:
5.2 seconds
Step-by-step explanation:
Traveling straight down: 90 * 3.5 = 315 feet down
Traveling up: 30 * 2.2= 66
315-66= 249
249/48= 5.1875 seconds
5.2 seconds <- rounded

Answer:
x= 2
Step-by-step explanation:
12. Using the equation y = -4(x + 2) give the:
a. x intercept
b. y intercept
Answer:
Step-by-step explanation:
y = -4(x + 2)
y = -4x + 2 *(-4)
y = -4x - 8
a) At x intercept, y= 0
-4x - 8 = 0
-4x = 8
x = 8/-4
x = (-2)
X intercept = -2
b) y- intercept = -8

un rectangulo tiene 28 cm de perimetro y unos de sus lados mide 4 cm ¿cuantos cuadrados de 2 cm por lado se mecesitan para armar ese rectangulo
Answer:
10 cuadrados
Step-by-step explanation:
Si uno de los lados de rectangulo es de 4cm entonces el lado parallelo tambien es de 4cm. Eso nos da 8cm del perimetro y nos quedan los otros dos lados que tienen la misma medida. Entonces dividimos el resto del perimetro por 2.
28 - 8 = 20cm
20cm / 2cm = 10cm
Ahora que tenemos todas las medidas podemos multiplicar el largo por el ancho para calcular el area del rectangulo
10cm * 4cm = 40[tex]cm^{2}[/tex]
el cuadrado de 2cm tendra un area de
2cm * 2cm = 4[tex]cm^{2}[/tex]
Ahora simplemente dividimos el area del rectangulo por el area del cuadrado para saber cuantos cuadrados necesitamos para armar ese rectangulo
40[tex]cm^{2}[/tex] / 4[tex]cm^{2}[/tex] = 10 cuadrados
Which ones make rectangles?
Answer:
b.
Step-by-step explanation:
To figure this out, you just need to fold those nets in your head and see if the edges line up and it forms the figure you want it to. From what I can tell, net b is the only one that would form a rectangular prism.

Joseph's lunch at a restaurant costs $13.00 without tax. He leaves the waiter a tip of 17% of the cost of the lunch, without tax. What is the total cost of the lunch, including the tip
Answer:
The total cost of the lunch including the tip is $15.21.
Step-by-step explanation:
To find the total cost of the lunch including the tip, first, you need to calculate 17% of the price of the lunch as the statement indicates that that is the tip Joseph leaves the waiter:
$13*17%=$2.21
Now, you need to add that amount to the price of the lunch:
$13+$2.21=$15.21
According to this, the answer is that the total cost of the lunch including the tip is $15.21.

Answer:
number 3 maybe . sorry if wrong
Answer:
Slope is 20 and y-intercept is 40.
Step-by-step explanation:
First, let's find slope. I'll be using the points (1,60) and (3,100).
[tex]m=\frac{y2-y1}{x2-x1}=\frac{100-60}{3-1}=\frac{40}{2}=20[/tex]
So the slope is [tex]m=20[/tex]. Now we need to find y-intercept. We can do this by using our slope and a point in the point-slope equation, [tex]y=mx+b[/tex]. I'll use the point (1,60).
[tex]y=mx+b\\60=20(1)+b\\60=20+b\\b=40[/tex]

A company that makes hair care products at 7000 people trying to shampoo of the 7000 people 28 had a mild allergic reaction what percent of the people had a mild allergic reaction
Answer:
0.4%
Step-by-step explanation:
Given that:
Number of people with mild allergic reaction = 28
Total number of people = 7000
To find:
Percentage of people who have a mild allergic reaction to the shampoo = ?
Solution:
First of all, let us understand how can we calculate percentage of a particular amount.
Percentage of a particular amount can be calculated by dividing the amount with the total amount and then multiplying it with 100.
Percentage of [tex]p[/tex] from [tex]q = \frac{p}q\times 100[/tex]
Here,
[tex]p = 28\\q =7000[/tex]
Therefore, the percentage of people who have mild allergic reaction:
[tex]\dfrac{28}{7000}\times 100\\\Rightarrow \dfrac{2800}{7000} \\\Rightarrow 0.4\%[/tex]
