Answer:
The linear equation is y = -5/8x+15 - Part A
15in - Part B
x = 24 - Part C
Step-by-step explanation:
Part A:
x = number of hours since she filled it
y = amount of ketchup remaining in the bottle
and knowing that we get the points (5, 11[tex]\frac{7}{8}[/tex]) and (8, 10)
Now get the slope of these points.
1. Slope formula
m = y2-y1/x2-x1
2. plug it in and you should get:
m = -5/8
3. Then substitute m = -5/8 and (x1, y1) into the point slope formula then solve for y to write the equation in slope intercept form
4. Point Slope Form = y-y1 = m(x-x1)
y-10 = -5/8(x-8) - substitute
y-10 = -5/8x+5 - distribute
y = -5/8x+15 - add 10 on both sides
The linear equation is y = -5/8x+15
Part B:
x represents the hours since she filled it, x = 0 is when she filled the dispenser
= 15in
Part C:
y = -5/8x+15
0 = -5/8x+15
5/8x = 15
x = 24

Answer:
D. y + 5 = 9/2(x + 7); –9x + 2y = 53
Step-by-step explanation:
The equation:
y - y 1 = ( y2 - y1 ) / ( x2- x1) * ( x - x1 )
y - ( - 5 ) = ( 4 + 5 ) / ( - 5 + 7 ) * ( x - ( - 7 ) )
y + 5 = 9/2 ( x + 7 )
y + 5 = 9/2 x + 63 /2 / * 2
2 y + 10 = 9 x + 63
- 9 x + 2 x = 53
Answer:
C ) y + 5 = 9/2 ( x + 7 ) ; - 9 x + 2 y = 53

I'll give you the brain thing if your right. plz help me
Answers
Answer: -0.8, 1/6, 1/4, 5/18
The negative number is the smallest. To find the order for the fractions, find a common denominator and then order them. The common denominator of 18, 4, and 6 is 36.
So, 5/18 becomes 10/36, 1/4 becomes 9/36, and 1/6 becomes 6/36.
So, the final order is -0.8, 1/6, 1/4, 5/18.

9, 18, 27, 36, 45, 54, 63, 72, 81, 90.
A:63
the next five multiples of 9 are 45, 54, 63, 72, and 81, and the LCM of 7 and 9 is 63.
Here are the first ten multiples of 7 and the first four multiples of 9:
Multiples of 7: 7, 14, 21, 28, 35, 42, 49, 56, 63, 70
Multiples of 9: 9, 18, 27, 36
Next five multiples of 9:
45, 54, 63, 72, 81
To find the least common multiple (LCM) of 7 and 9, we can identify the smallest multiple that both numbers share. From the lists, we see that the least common multiple of 7 and 9 is 63.
Therefore, the next five multiples of 9 are 45, 54, 63, 72, and 81, and the LCM of 7 and 9 is 63.

graph f(x)=3x+5 and g(x)=3x-2
Answers
Answer:
Two parallel lines
Step-by-step explanation:
the slopes are the same: slope = 3
f(x) 3x + 5 g(x) = 3x - 2
Pick at least three x values and find their corresponding values for y. Remember the f(x) and g(x) represent y
f(x) = 3x + 5 g(x) = 3x - 2
y = 3x + 5 y = 3x - 2
let x = 0 y = 3(0) + 5 y = 3(0) - 2
y = 5 y = -2
Ordered pair (0, 5) (0, -2)
Let x = 1 y = 3(1) +5 y = 3(1) - 2
y = 8 y = 1
ordered pair (1, 8) (1, 1)
Let x = -1 y = 3(-1) + 5 y = 3(-1) - 2
y = 2 y = -5
ordered pair (-1, 2) ( -1, -5)
Locate the ordered pairs and draw the graph on the lines.
you will graph two parallel lines

Answer:
4.
Step-by-step explanation:
Slope = (y2-y1)/(x2-x1)
- that is rise / run.
We use the points (2, 8) and (2,0) ( - the last point is vertically below (2,8) and is on the x axis)
Here y2 = 8, y1 = 0, x2 = 2 and x1 = 0.
So the slope = (8-0)/(2-0)

Mia
Step-by-step explanation:
The slope is 6 using y = mx + b where m is the slope
Ordered pair (0, 4) and (-1, -2) are points on the blue line. Check to see if the slope = 6.
Slope = (change in the y-values)/(change in the x-values)
Slope = (-2 - 4)/(-1 - 0)
Slope = -6/ -1
Slope = 6

The length of a rectangle is 3 ft longer than its width.
If the perimeter of the rectangle is 70 ft, find its length and width.
Answers
Answer:
The length is 16 and the width is 19.
Step-by-step explanation:
We'll represent width with the letter w, and length with l.
w = l + 3
The perimeter is all four sides, so perimeter = 70ft = (2w) + (2l)
We will replace w with l + 3.
70 = 2(l + 3) + (2l)
2 (l + 3) = (l + 3) + (l + 3)
and 2l = l + l, so
70 = l + 3 + l + 3 + l + l = 4l + 6
We subtract 6 from both sides.
64 = 4l
then we divide both sides by 4
16 = l
Remember width = length + 3, so
16 + 3 = w
19 = w
Just to check:
2(length) + 2(width) = perimeter
2(16) + 2(19) = 70
32 + 38 = 70
