The equation that represents the road is y= ______
Answers
Answer:
[tex] y = \frac{1}{6}x - 5 [/tex]
Step-by-step explanation:
The equation that represents the road can be written as [tex] y = mx + b [/tex]
Find, m = slope, and b = y-intercept of the line.
Using two points on the line, (-6, -6) and (6, -4), find the slope:
[tex] slope(m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{-4 -(-6)}{6 -(-6)} = \frac{2}{12} = \frac{1}{6} [/tex]
Substitute x = -6, y = -6, and m = ⅙ into [tex] y = mx + b [/tex] to find b.
[tex] -6 = \frac{1}{6}(-6) + b [/tex]
[tex] -6 = -1 + b [/tex]
Add 1 to both sides
[tex] -6 + 1 = b [/tex]
[tex] -5 = b [/tex]
Substitute m = ⅙, and b = -5 into [tex] y = mx + b [/tex].
✅The equation that represents the road would be:
[tex] y = \frac{1}{6}x + (-5) [/tex]
[tex] y = \frac{1}{6}x - 5 [/tex]

Laura has to three cats: The ratio of Socks weight to princess weight is 4:5 The ratio of princesses weight to Luna's weight is 6 :7. What is the ratio of socks weight to Luna's weight?
Answers
Answer:
s : l = 24 : 35
Step-by-step explanation:
Let
Socks weight = s
Princess weight = p
Luna's weight = l
The ratio of Socks weight to princess weight is 4:5
s : p = 4 : 5
s / p = 4 / 5
The ratio of princesses weight to Luna's weight is 6 :7
p : l = 6 : 7
p / l = 6 / 7
What is the ratio of socks weight to Luna's weight
Multiply both given ratios
s / p * p / l = 4 / 5 * 6 / 7
p cancel out
s / l = 24 / 35
s : l = 24 : 35
Ratio of socks weight to Luna's weight is 24 : 35
Write an equation in slope-intercept form for the line with slope -6 and y-intercept 6.
Answers
Answer:
y = -6x + 6
Step-by-step explanation:
y = mx + b
y = -6x + 6
The equation in slope-intercept form for the line with slope -6 and y-intercept 6 is y = -6x+6
What is the slope-intercept form of a line?The slope intercept formula y = mx + c is used when you know the slope of the line to be examined and the point given is also the y intercept (0, c).
Given that, a line has slope -6 and y-intercept 6.
The general form of the slope-intercept form for the line is y = mx+c, where m is the slope and c is the y-intercept.
Therefore, the required equation will be =
y = -6x+6
Hence, the equation in slope-intercept form for the line with slope -6 and y-intercept 6 is y = -6x+6

Bath and 1 yard of ribbon. She is 1/2 yard for project. She wants to divide the rest of the ribbon into pieces 1/4 yards long. How many 1/4 pieces of ribbon can she make
Answers
Answer:
2
Step-by-step explanation:
Given:
Total length of ribbon = 1 yard
Length of ribbon used for project = [tex]\frac{1}{2}[/tex] yard
Length of ribbon the rest of ribbon is to be divided = [tex]\frac{1}{4}[/tex] yard
To find:
The number of ribbons of length [tex]\frac{1}{4}[/tex] yard that can be made = ?
Solution:
Length of ribbon left after the 1 yard ribbon is used for project can be calculated by subtracting the length of ribbon used from the initial length of ribbon.
i.e.
Length of ribbon left = [tex]1-\frac{1}{2} =\frac{1}{2}[/tex] yard
Now, number of ribbon of length [tex]\frac{1}{4}[/tex] yard can be found be dividing the length of ribbon left with the length of ribbon pieces to be cut.
i.e.
Number of ribbons:
[tex]\dfrac{\frac{1}{2}}{\frac{1}{4}}\\\Rightarrow \dfrac{1}{2}\times 4 = 2[/tex]

The class will meet each week and your friend will charge each student the same fee for the whole course. Your friend's profit depends on how many students enroll in the course and how much she charges each student.
If your friend charges each student D dollars for the course, define a function, p, that relates the number of students who take the dance course, n, to the profit, p(n).

Yeast , a key ingredient bread , thrives within the temperature range of 90° F to 95°F . Write and graph an inequality that represents the temperatures where yeast will NOT thrive .
Answers
Answer:
Please find attached the required graph of the inequality representing the temperatures yeast will NOT thrive
Step-by-step explanation:
The given parameters are;
The temperature range, y, in which yeast thrives is 90°F ≤ y ≤ 95°F
Therefore, the temperature range, y', in which yeast will not thrive is 90°F > y and y > 95°F
The graph of the inequality that represents the temperature is therefore given as shown in the attached drawing.
Answer:
Picture shown below
Step-by-step explanation:
Yeast thrives in temperatures within the temperature range of 90°F to 95°F. Any temperature above or below those limits hinders yeast production. An inequality to represent where yeast will not thrive is shown, where x represents the temperatures where the yeast will not thrive.

Answers
The slope that passes through the points (–2, 1) and (–4, –7) is 4.
The slope formula can be represented below:
m = y₂ - y₁ / x₂ - x₁Therefore, the slope that passes through the points (–2, 1) and (–4, –7) can be found below
m = - 7 - 1 / -4 - (-2)
m = - 8 / -4 + 2
m = -8 / -2
m = 4.
Therefore, the slope is 4.
