A neighborhood is having a community garage sale, where all items cost the same amount. If you buy 7 items, the price is $2.45, and if you buy 11 items, the price is $3.85. If you graphed the relationship between x, the number of items sold, and y, the total price in dollars, what would be the slope of the line?
The slope of the line is 0.35
x = number of items sold
y = total price in dollars
Therefore,
using slope formula,
The slope is rise over run. The slope of a line is the measure of its steepness.
Slope equation:m = y₂ - y₁ / x₂ - x₁where
y₂ = 3.85
y₁ = 2.45
x₂ = 11
x₁₁ = 7
Therefore,
m = 3.85 - 2.45 / 11 - 7
m = 1.4 / 4
m = 0.35

Answer:
1)2x -y+2=0
2)-x +4y +8 = 0
Step-by-step explanation:
Here two equations are given to us and we need to write them in Standard form . The given equations are linear equation in two variables and their Standard form is ,
[tex]\implies ax + by + c = 0 [/tex]
Where a , b and c are constants .1) y - 4 = -2(x +3)
Open the brackets on RHS ,
[tex]\implies y - 4 = -2x -6 [/tex]
Transpose all the terms to LHS ,
[tex]\implies 2x - y -4 +6 = 0[/tex]
Add the constant terms ,
[tex]\implies \boxed{ 2x - y +2 =0} [/tex]
Hence the equation in standard form is 2x -y +2=0.
2) y = ¼x -2
Add 2 on both sides ,
[tex]\implies y + 2 = \dfrac{1}{4}x [/tex]
Multiply both sides by 4 ,
[tex]\implies 4y +8 =x [/tex]
Subtract x on both sides,
[tex]\implies \boxed{ -x + 4y + 8 =0}[/tex]
Hence the equation in standard form is -x +4y +8=0 .
3. If a store had a 20% discount on a coat that was $29.99, how much would you have to pay for the coat?

Answer:
b=10
h=8
area of triangle=1/2b×h
=1/2×10×8
=40
hope it helps you
make me brainliest plz
Answer:
40 units²
Step-by-step explanation:
Formula to find the area of a triangle is :
Area = [tex]\frac{1}{2}[/tex] × base × height
Given that,
Base = 10 units
Height = 8 units
Let us solve now.
Area = [tex]\frac{1}{2}[/tex] × base × height
Area = [tex]\frac{1}{2}[/tex] × 10 × 8
Area = [tex]\frac{1}{2}[/tex] × 80
Area = 40 units²
Hope this helps you :-)

Expand 2(q+3) please
Answer:
2q + 6Step-by-step explanation:
Expand the expression with the help of distributive property.
2(q + 3)=> (2 x q) + (2 x 3)=> 2q + 6Hence, the expanded expression is 2q + 6.
Answer:
2q +6
Step-by-step explanation:
The distributive property is used for this purpose. The factor outside parentheses (2) multiplies each of the terms inside parentheses (q, 3).
2(q +3) = 2·q +2·3 = 2q +6
_____
Additional comment
It might help to think of the parentheses as a "bag" containing one "q" and 3 tokens. The number outside parentheses tells you how many "bags" you have. Expanding the expression is equivalent to dumping out the bags and describing the total contents:
2(q +3) = (q +3) +(q +3) . . . . multiplication is the same as repeated addition
= (q +q) +(3 +3)
= 2q +6

Helga teaches dance classes. She charges for the classes as shown below. Option 1: $80 per month for five classes Option 2: $900 per year for 60 classes Option 3: $174 for 12 classes Calculate the constant of proportionality for each class. Then select the true statements below. Option 1 and option 3 cost the same amount per class. Option 3 costs the least amount per class. Option 2 and option 3 cost the same amount per class. Option 1 costs $1 more per class than option 2 costs per class. Option 3 costs $1 more per class than option 1 costs per class.
Answer:Option 3 costs the least amount per class.
Option 1 costs $1 more per class than option 2 costs per class.
Step-by-step explanation:blah blah blah
Using the constant of proportionality that is determined, the true statements are:
B. Option 3 costs the least amount per class.
D. Option 1 costs $1 more per class than option 2 costs per class.
How to Find Constant of Proportionality?The constant of proportionality, k, between variables y and x is, k = y/x.
Amount = y
Number of classes = x
Constant of proportionality = y/x.
Option 1:
Constant of proportionality = 80/5 = $16 per class
Option 2:
Constant of proportionality = 900/60 = $15 per class
Option 3:
Constant of proportionality = 174/12 = $14.5 per class
The lowest cost per class is Option 3.
Option 1 is $1 more costlier than Option 2.

C. 0.7 yd³Step-by-step explanation:
Find the volume of cylinder:
V = πr²hConvert the dimensions into yards:
d = 24 inches = 24/36 yards = 2/3 yards ⇒ r = 1/2d = 1/2*2/3 = 1/3 yardsh = 6 feet = 6/3 yards = 2 yardsFind the volume by substituting the values:

Step-by-step explanation:
The legs of the right triangles are drawn along the grid lines. You can count the grid lines to see how long they are. Use the given formula to find the square of the hypotenuse, then take the square root. The hypotenuse of each triangle is the straight-line distance between its end points.
It should be no surprise that 3^2 +4^2 is more than 3^2 +3^2, so the length from B to C will be longer than from A to C.

if a 12 ounce box of cereal costs $3.84, how many ounces should be in a box marked $2.49?
answer quick I will mark brainliest..
Answer:
7.78 ouncesStep-by-step explanation:
We know that:
12 ounce box of cereal = $3.84Work:
12/3.84 ounce box of cereal = $1=> 12/3.84 x 2.49 box of cereal = $2.49=> 7.78 ounces (Rounded to nearest hundredth) = $2.49Hence, 7.78 ounces cost $2.49.
7.8125 ounces
Step-by-step explanation:
Based on given conditions,
[tex] \frac{2.49 \times 12}{3.84} \\ = > \frac{ \frac{249}{100} \times 12 }{ \frac{384}{100} } [/tex]
[tex] = > \frac{ \frac{249}{25} \times 3 }{ \frac{96}{25} }[/tex]
[tex] = > \frac{249}{25} \times 3 \times \frac{25}{96}[/tex]
[tex] = > 83 \times 3 \times \frac{1}{32} [/tex]
[tex] = > \frac{83 \times 3}{32} [/tex]
[tex] = > \frac{249}{32}[/tex]
[tex] = > 7.78125ounces[/tex]
By rounding off,
[tex] = > 7.9ounces[/tex]
