Answer:
slope = - 2
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 5) and (x₂, y₂ ) = (4, 1)
m = [tex]\frac{1-5}{4-2}[/tex] = [tex]\frac{-4}{2}[/tex] = - 2
: ( 3, 10 ) and ( 4, 6 )
Answer:
the slope is M=-4
Step-by-step explanation:
Answer:
to find slope you need to
Step-by-step explanation:
first the slope formula
[tex]\frac{y2}{y1}\frac{x2}{x1}[/tex]
then you replace them with the numbers
[tex]\frac{-10-6}{4-3}[/tex]
solve equasion
[tex]-10-6=-16\\4-3=1[/tex]
[tex]\frac{-16}{1}[/tex]
slope=-16
Find the slope that passes through (4,9) and (6,8)

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

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.

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.
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

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.
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
"This summer, the water level of Lake Conroe changed by a rate of -1.5 feet per month. The water level at the beginning of May was 187 feet above sea level. What was the water level at the end of four months?" heelpppp asaapp
Answer:
181 feets
Step-by-step explanation:
Given that:
Rate of change in water level = - 1.5 feets per month
Water level at beginning of May = 187 feets above sea level
Water level at the end of 4 months =?
Total change after four months = rate of change per month * number of months
= - 1.5 * 4 = - 6 feets
Hence water level after 4 months :
187 feets + (-6 feets)
187 feets - 6 feets
= 181 feets

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]
I hope this helps!
I’ll give 10 points if you help!

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
3x3=9

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
Samantha plays a trivia game. She earns 3 points for each
correct answer and loses 0.75 points for each incorrect
answer. She gets 11 correct answers and 4 incorrect
answers.
What is her score for the game?
Answer:
33/36
Step-by-step explanation:
take 0.75 x 4 = 3
then take
11 x 3 = 33
total score = 36
36 - 3 = 33
so the answer is 33/36
Answer:
Samantha would score 30 points
Step-by-step explanation:
If we multiply 11 x 3 we would get 33, the 11 represents the correct awnsers and the 3 represents the points
If we multiply 0.75 and 4 we get 3, this represents the incorrect
Next I subtracted 33 and 3 to get the answer of 30.

find the product if the sum of two numbers is 131 and the difference is 35
Please help: this is due in one hour. Please write let statements and equations.
Answer:
Step-by-step explanation:
let the two numbers be : x and y
x +y =131 , x-y= 35
by omitting :
x+y=135
x-y=35
cancel the ys with each other and add each side together
2x=135+35 = 170
to get x
x=170/2 =85
now u have the x time to get the y u can get it for any equation u like
85+y=135
y=135-85 = 50
the product = 85 x 50 = 4250
