Use the point and the slope to graph each line. Write the equation of the line. The line contains point (2, –2) and is perpendicular to a line with slope –1.
Answers
Answer:
y = x - 4
Step-by-Step Explanation:
Perpendicular lines have slopes that are negative reciprocals—multiplying their slopes result in -1.
Given the slope of a line m = -1, then it means that the slope of the other line must be 1 (because multiplying the slope of line 1 (m1 = -1), and the slope of the other line (m2 = 1) results in: -1 × 1 = -1).
Therefore, given the slope of line 2 (m2 = 1), and the point (2, -2), we could plug these values into the slope-intercept form and solve for the y-intercept (b):
y = mx + b
-2 = 1(2) + b
-2 = 2 + b
Subtract 2 from both sides to solve for b:
-2 - 2 = 2 - 2 + b
-4 = b
Therefore, the y-intercept (b) = -4.
Hence, the equation of the perpendicular line is: y = x - 4

Answers
The graph of the equation y = -0.75x + 6 is shown in figure.
And, The correct statement about the graph is,
d. The graph will have a slope of -0.75.
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The equation is,
⇒ y = -0.75x + 6
Now,
The graph of the equation y = -0.75x + 6 is shown in figure.
Clearly, It is not passing through the origin.
And, It cannot cross the x-axis at (6,0).
Since, The standard form of the equation of line is,
⇒ y = mx + c
Where, m is the slope of the line.
So, By comparing we get;
The slope of the line (m) = - 0.75
Thus, The correct statement about the graph is,
d. The graph will have a slope of -0.75.

Roxie is a show dog her trainer wants her to have a beautiful and brilliant coat. The veterinarian suggested a special diet for the trainer to follow each feeding Roxie eats 2/3 of a can of wet dog foods 1/8 of a bag of dry food and 3/5 a patty of special meat the special meat comes in a package of 6 patties Roxie has two meals a day
Answers
Answer: the answers are below
Step-by-step explanation:
1 meal = 2/3 of a can of wet dog food, 1/8 of a bag of dry dog food, and 3/5 a patty of special meat
Food for 1 day: 2 meals = 2(2/3) = 4/3 of a can of wet dog food, 2(1/8) = 1/4 of a bag of dry dog food, and 2(3/5) = 6/5 a patty of special meat
The trainer goes to the store and buys 24 cans of wet food, 4 bags of dry food and 3 packages of meat (3*6 = 18 patties)
He has:
there is wet food for: 24/(4/3) = 24*3/4 = 18 days
there is dry food for: 4/(1/4) = 4*4 = 16 days
there is special meat food for: 18/(6/5) = 18*5/6 = 15 days
since the minimum for 15, 16 and 18 is 15 the dog will have food for 15 days and first he will run out of special meat.
1. Roxie will be fed for 15 days before the trainer needs to buy more food.
2. The trainer will run out of the special meat first, as it will last for 15 days.
3. After the special meat runs out, there will be 3 cans of wet food and 1 bag of dry food left.
4. The trainer needs to buy 96 more cans of wet food, 19 more bags of dry food, and 36 more patties of special meat to last 90 days.
5. The minimum amount of food the trainer could buy is 80 cans of wet food, 15 bags of dry food, and 72 patties of special meat, which would last for 60 meals (30 days).
Step 1: Calculate the daily consumption of each type of dog food.
Wet food: 2/3 can per meal * 2 meals per day
= 4/3 cans per day.
Dry food: 1/8 bag per meal * 2 meals per day
= 1/4 bag per day.
Special meat: 3/5 patty per meal * 2 meals per day
= 6/5 patties per day.
Step 2: Calculate the total food available for Roxie.
Wet food: 24 cans purchased.
Dry food: 4 bags purchased.
Special meat: 3 packages (3 * 6 patties = 18 patties) purchased.
Step 3: Calculate the number of days the food will last.
Days of wet food: 24 cans / (4/3 cans per day)
= 24 * 3/4
= 18 days.
Days of dry food: 4 bags / (1/4 bag per day)
= 4 * 4
= 16 days.
Days of special meat: 18 patties / (6/5 patties per day)
= 18 * 5/6
= 15 days.
Step 4: Determine which type of dog food will run out first.
The special meat will run out first, after 15 days.
Step 5: Calculate how much of the other two types of dog food will be left after the first type runs out.
After 15 days, Roxie will still have
= 18 - 15
= 3 cans of wet food left.
After 15 days, Roxie will still have
= 16 - 15
= 1 bag of dry food left.
Step 6: Plan for 90 days.
The total number of patties needed for 90 days
= (6/5 patties per day) * 90 days
= 108 patties.
and, the trainer needs to buy
= 108 / 6 = 18 packages
- For wet food, Roxie needs
= (4/3 cans per day) * 90 days
= 120 cans.
The trainer already has 24 cans, so she needs to buy
= 120 - 24 = 96 more cans.
- For dry food, Roxie needs
= (1/4 bag per day) * 90 days = 22.5 bags.
Since the trainer can't buy half a bag, she needs to round up to 23 bags.
Step 7: Minimum amount of food to buy to finish all of it after a certain number of meals.
Minimum amount of wet food to buy:
= (4/3 cans per day) * 60
= 80 cans.
Minimum amount of dry food to buy:
=(1/4 bag per day) * 60
= 15 bags.
Minimum amount of special meat to buy:
=(6/5 patties per day) * 60
= 72 patties.
Therefore, the trainer could buy a minimum of 80 cans of wet food, 15 bags of dry food, and 72 patties of special meat, and Roxie would finish all of it after 60 meals (30 days).

find x I guess. (I don't know what to say)
Answers
Answer:
x = 28
Step-by-step explanation:
1. ∠AOD and ∠COB are equivalent because they're vertical angles (opposite pair of angles that are formed from the intersection of two lines). That means that 3x + x + x + 12 = 152.
2. (Solving 3x + x + x + 12 = 152)
Step 1: Simplify both sides of the equation.
[tex](3x+x+x)+(12)=152[/tex] [tex]5x + 12 = 152[/tex]Step 2: Subtract 12 from both sides.
[tex]5x + 12 - 12 = 152 - 12[/tex] [tex]5x = 140[/tex]Step 3: Divide both sides by 5.
[tex]\frac{5x}{5} = \frac{140}{5}[/tex] [tex]x = 28[/tex]Step 4: Check if solution is correct.
[tex]3(28)+(28)+(28)+12 = 152[/tex] [tex]84 + 28 + 28 + 12 = 152[/tex] [tex]112 + 28 + 12 = 152[/tex] [tex]140 + 12 = 152[/tex] [tex]152 = 152[/tex]Therefore, x = 28.
Answer:
x = 28
Step-by-step explanation:
Based on the vertical angles theorem, ∠AOD ≅ ∠COB.
• ∡AOD = 152°
• ∡COB = 3x + x + x + 12
To find the value of x, set up the equation that can be formed from the given information:
3x + x + x + 12 = 152 First, combine like terms.
5x + 12 = 152 Subtract 12 from both sides to isolate the variable.
5x = 140 Divide both sides by 5 to find the value of x.
x = 28
The value of x is 28°.
