Answer: Slope is undefined. x=0
slope calculation: -3-4/0-0 = -7/0 and anything divided by 0 is undefined
the x value in the coordinates is 0 so it’s x=0 line.
vertical lines always have undefined slopes
Answer:
[tex]x=0[/tex]
Step-by-step explanation:
So first of all we need the slope of the line we are trying to findWe get the slope by using the following formula [tex]slope=\frac{y_2-y_1}{x_2-x_1}[/tex] So when you have two pairs of points, it will be [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] so our points are; (0,4) the first point, so [tex]x_1=0,y_1=4[/tex] and(0.-3) the second point, so [tex]x_2=0,y_2=-3[/tex] Put this in our equation [tex]slope=\frac{(-3)-(4)}{(0)-(0)}=\frac{-7}{0}[/tex] Oh no, that can't be right, any number divided by zero is undefined, meaning can't be answered. So this line has no slope So how do we know the equation? Remember, (a) if the line is horizontal, then the slope is 0,(b) if the line is vertical then the slope is undefinedSo our line is vertical, meaning it is an equation of xIf it were horizontal it would be an equation of ySo vertical, it is [tex]x=??[/tex] How do we know what x equals? Just look at our points (0,4) and (0,-3)For both of them [tex]x=0[/tex] and this is our equation!In which choice are all four points on the same straight line?

Given the answer for part D, write an expression that will tell you the direction the robot is going if, in the course of its journey, it turns left 21 times and turns right 22 times. Does the order the robot makes the turns in matter for the purpose of knowing the direction it is finally facing?
The answer to part D is in the picture...
Answer:
[(i^21) - (i^22)]d
the direction will not matter because the direction will always be the same no matter what order you choose
Step-by-step explanation:
This is the answer
The expression that will tell you the direction the robot is going will be ((i)²¹*(-i)²²)d i.e. right to the initial direction. And the order does not matter for the direction it is finally facing.
What is rotation in complex plane?When in the complex plane, the line is rotated clockwise, then the line is multiplied by -i and when the line is rotated anti-clockwise, then the line is multiplied by i.
A right turn is the clockwise rotation of the direction vector by the angle of 90°. It is equivalent to multiplying the complex number by -i.
A left turn represents a counterclockwise rotation of the direction vector by the angle of 90°. It is equivalent to multiplying the complex number by i.
Here assume the initial direction vector of the robot is d
the robot is turned to the left 21 times. so now the direction vector will be di²¹. Then it is rotated right 22 times, now the direction vector will be (di²¹)*(-i)²²=d((i)²¹*(-i)²²).
So, now the direction that the robot is going= d((i)²¹*(-i)²²)= di²¹⁺²²=di⁴³= d(-i)= -di
means the robot is the right of the initial direction.
Now the expression that shows the direction that the robot is going is d((i)²¹*(-i)²²).
The order does not matter as the direction will always be the same irrespective of the order.
Therefore The expression that will tell you the direction the robot is going will be ((i)²¹*(-i)²²)d i.e. right to the initial direction. And the order does not matter for the direction it is finally facing.

Half the value of 3x-9 is x+37. What is the value of x?
Answer:
x = 83
Step-by-step explanation:
You know that half of 3x-9 is x+37. That means 2(x+37) = 3x-9. Solve the left side of the equation. You will get 2x+74. Now the whole equation is 2x+74=3x-9. Well, move the like terms to each of their sides. You will now have 74+9 = 3x-2x. Simplify and you will get 83 = x.
Hope this helps! Please mark me as brainliest!
Answer:
x=83
Step-by-step explanation:
Since we know that half of 3x-9 is x+37, that's the same as saying the double of x+37 or 2(x+37) is equal to 3x-9. So, we can write this equation: 3x-9=2(x+37). Now, all we have to do is use simple algebra to solve the problem:
Steps Justification
3x-9=2(x+37) Original Equation
3x-9=2x+74 Distributive Property of Equality
x-9=74 Subtraction Property of Equality (Subtract 2x from both sides)
x=83 Addition Property of Equality (Add 9 to both sides)

A. the set of real numbers less than 0
B. the set of real numbers less than 4
C. the set of real numbers greater than 4
D. the set of real numbers greater than 0
The range of the function f(x) = -3x + 4 is all real numbers
None of the options is correct
The given function is:
f(x) = -3x + 4
The range of a function is the set of its valid output values
The function f(x) = -3x + 4 does not have any constraint, neither does it have any value that will make the function f(x) to be undefined.
Therefore, both the domain and the range of the function is a set of all real numbers

Mr. Smith has an online cooking show. Before he films an episode about baking the perfect pound cake, he prepares his ingredients. His recipe calls for 2 1 /2 cups of sugar for the cake and 1 1/ 4 cups of sugar for the vanilla glaze. How many 1 /4 -cup scoops of sugar does he need? Write your answer as a whole number, fraction, or mixed number. Simplify any fractions.
Answer:
15
Step-by-step explanation:
We are given
Mr. Smith's recipe calls for 2 1/2 cups of sugar for the cake and 1 1/4 cups of sugar for the vanilla glaze.
The total amount of sugar he would need
2 1/2 + 1 1/4
= (2 + 1) + (1/2 + 1/4)
= 3 3/4 cups of sugar.
We need this amount of sugar in 1/4 cup scoops.
This is calculated as:
let x be the number of scoops needed
x * 1/4 = 3 3/4
x* 1/4 = 15/4 ( 3 3/4 = 15/4)
x= 15
Therefore, he would be needing 15 , 1/4 cup scoop of sugar

26) Hailey is 3 times as old as Maverick.
The sum of their ages is 48 years. How
old is Maverick?
Let H = Hailey's age and M = Maverick
Hailey is 3 times as old as Maverick: H = 3M
The sum of their ages is 48 years: H + M = 48
Since H = 3M, substitute 3M in place of H in the second equation:
H + M = 48
3M + M = 48
4M = 48
M = 12
Maverick is 12 years old. Hailey = 3M = 3(12) = 36 years old.

A store sells mugs Each mugs cost the same amount. During a sale the store reduces of each mug by $1.75 Wen spends $28.20 on 5 mugs at the sale price what was the price of one mug before the sale
Answer: $7.39
Step-by-step explanation:
From the question, we are informed that a store sells mugs and that each mugs cost the same amount. We are further told that during a sale the store reduces of each mug by $1.75 and that Wen spends $28.20 on 5 mugs.
Since the store reduced $1.75 on each mugs, the amount that When would have paid without the discount will be:
= $28.20 + ($1.75 × 5)
= $28.20 + $8.75
= $36.95
The price of one mug before the sale will then be:
= $36.95 / 5
= $7.39
