Answer:
Equation: y + 1 = -2(x - 0) OR y + 3 = -2(x - 1)
Slope: -2
Y-intercept: (0, -1)
Step-by-step explanation:
First, create an equation in point-slope form using ONE point. Using (0,-1):
y - y1 = m(x - x1)
y + 1 = m(x - 0)
Then, use both points to find slope:
[tex]\frac{y2-y1}{x2-x1} =m[/tex]
[tex]\frac{-1-(-3)}{0-1}[/tex]
[tex]\frac{2}{-1}=m=-2[/tex]
Then, plug the slope into the equation and rewrite in the form of y=mx+b:
y + 1 = (-2)(x - 0)
y + 1 = -2x
y = -2x - 1
-1 = b OR (0, -1)
Final answers:
Equation: y + 1 = -2(x - 0) OR y + 3 = -2(x - 1)
Slope: -2
Y-intercept: (0, -1)

Randall wants to buy a pizza. He can select from 5 different sizes, 4 types of crust, and 12 toppings for his pizza. Which of the following shows how to find all the different possible choices of 1 size, 1 crust, and 1 pizza topping Randall can buy?
Answers
Answer:
240
Step-by-step explanation:
5x4x12=240
if you multiply the amount of sizes he can get times the amount of crust sizes he can get you get the pizza it's self (20)
now including the toppings (12) this means 20x12 gets you the amount of toppings on those induviduale pizza's.

Answer:
109
Step-by-step explanation:
the sum of 37 and 72 is equal to x
proof:
37+72 = 109
three angles of a triangle form 180 degree
to find the angle which is not given,
180 - 109 = 71
as you can see, angle with the measure 71 degree and angle x form a straight line, which means their sum is 180
so,
x = 180 - 71
x = 109
that means ,
=> 37+72 = x
=> 109 = 109 [ 37+72 = 109, x = 109]
hope this helps :)
Answer:
Option D is correct answer that is 109° .Step-by-step explanation:
Question : -Find the value of x in this triangle .
Given : -Angle 1 = 37°Angle 2 = 72°Angle 3 = y° ( We are assuming it as y )Angle 4 = x°To Find : - We have to find the value of x .Solution : -We know that sum of all the interior angles of triangle is equal to 180° . Then ,
Angle 1 + Angle 2 + Angle 3 = 180°37° + 72° + Angle 3 = 180°109° + Angle 3 = 180°Angle 3 = 180° - 109°Angle 3 = 71°Therefore , Angle y = 71° .
Now , We know that Angle 3 and Angle 4 is equal to 180° because they are Linear pair . So ,
Angle 3 ( y )+ Angle 4 ( x ) = 180°71° + x° = 180°x° = 180° - 71°x° = 109°Therefore , value of Angle x is 109° .
#[tex] \rm{Keep \: Learning}[/tex]You want to rent a car. The cost is $120 per day. You are allowed 100 miles per day--but any mileage above that amount will cost $0.35 per mile. You rent the car for 5 days, and drive 925 miles. The car gets 25 miles to the gallon, and a gallon of gas costs $4.
pls help im so confused
Answers
Answer:
600$ rent for 5 days,
around 185 miles a day, meaning you are paying 0.35$x85=29.75 extra a day.
adding up to 120 a day+29.75=149.75 a day.
149.75x5=748.75 for 5 days not including gas prices.
925/25=185 gallons of gas. 4 dollars per gallon, meaning that 185x4=740 extra dollars in gas
748.75+740=1488.75$ for the entire trip.

Marco picked 8 1/2
pounds of apples at an orchard last weekend. He used
1/4
of the apples to make a pie for a party. Then, he used 3 1/8
pounds of apples to make applesauce. How many pounds of apples does Marco have left?
Answers
Answer:
3 1/4 pounds
Step-by-step explanation:
Marco starts with 8 1/2 pounds, to make things easier rewrite it as 8.5.
He uses 1/4 (or .25) of the apples. 8.5 * .25 = 2.125. Subtract this 2.125 from the 8.5 since it's what's being used. 8.5 - 2.125 = 6.375
Then he uses 3 1/8 (or 3.125) pounds. Subtract 3.125 from the 6.375 we got previously to get 3.25.
Marco has 3.25 pounds left which can be rewritten as 3 1/4 pounds.

Dante is solving the system of equations below.
r+S-=-4
2r-35+=1
3r-2s+21= 3
He writes the row echelon form of the matrix. Which matrix did Dante write?
Answers
Answer:
The answer is the first matrix. Image attached.
Step-by-step explanation: Given that Dante is solving the system of equations:
In solving the above system of equations, Dante writes the row echelon form of the matrix. We are to select the correct row echelon of the matrix that he wrote.
We know that a matrix is said to be in row echelon form if the leading entry in each nonzero row is a 1 and each column containing a leading 1 has zeros everywhere else.
In the given options, these conditions are satisfied by the first option only. And also, if we write the solution from this matrix, we will have
r = -1, s = 0 and t = 3.
If we substitute these values in the given system, it will get satisfied.
Thus, the first matrix, attached herewith, is the correct matrix.
