Solve the system by graphing. It is REQUIRED to check your solution. Show work for this problem on your work page.
y = x -1
y = -2x -4
Answer:
y=x-1
y=-2x-4
although I cant summon a graph for this one, I can give cords
for first graph (-2,-3),(-1,-2),(0,-1), (1,0),(2,1)
For second graph the slope is down 2 over 1, and begins at (0,-4).
(-2,0)(-1,-2),(0,-4),(1,-6),(2,-8)
Let's solve for x.
y=x−1
Step 1: Flip the equation.
x−1=y
Step 2: Add 1 to both sides.
x−1+1=y+1
x=y+1
Answer:
x=y+1
---------------------------------
Let's solve for x.
y=−2x−4
Step 1: Flip the equation.
−2x−4=y
Step 2: Add 4 to both sides.
−2x−4+4=y+4
−2x=y+4
Step 3: Divide both sides by -2.

Based on the cone shown, which statements are correct?
A)
B)
If the volume is 47 cm”, then the height of the cone is approximately 5 cm.
If the height is 10 cm, then the volume of the cone is approximately 74
cm?
If the height is 20 cm, then the volume of the cone is approximately 289
cm?
The equation v = {1x3)?h can be used to find the volume of the cone.
C)
D)
E)
The equation -
3V
7(3)
can be used to find the height of the cone.
Answer:
A,c,d
Step-by-step explanation:
The solution is Option A.
If the volume is 47 cm³ , then the height of the cone is approximately 5 cm and volume of cone is given by ( 1/3 ) πr²h
What is a Cone?
A cone is a three-dimensional shape in geometry that narrows smoothly from a flat base (usually circular base) to a point(which forms an axis to the center of base) called the apex or vertex.
The volume of a cone is given by the equation
Volume of Cone = ( 1/3 ) πr²h
where r is the radius of the cone
h is the height of the cone
Given data ,
Let the radius of the cone be = r
Now , the value of r = 3 cm
So , the equation will be
The volume of the cone is given by the formula ,
Volume of Cone = ( 1/3 ) πr²h
where r is the radius of the cone
h is the height of the cone
a)
If the volume is 47 cm³, then the height of the cone is approximately 5 cm
So , substitute the values in the equation , we get
Volume of Cone = 47 cm³
So ,
( 1/3 ) πr²h = 47 cm³
Radius of cone r = 3 cm
Height of cone h = 5 cm
( 1/3 ) πr²h = 47 cm³
( 1/3 ) x 3.14 x 3 x 3 x 5 = 47
3.14 x 15 = 47
47 = 47
Therefore , the solution is true
Hence , If the volume is 47 cm³, then the height of the cone is approximately 5 cm and the volume of cone is given by ( 1/3 ) πr²h

A gardener is planting two types of trees: Type A is 36 inches tall and grows at a rate of 15 inches per year. Type B is 48 inches tall and grows at a rate of 10 inches per year. a. Model the situation as a system of linear equations. Use x to represent the number of year and y to represent the height of each tree. b. Determine exactly how many years it will take for these trees to be the same height. You can check in Desmos for the answer, but you must show all algebraic work. c. What is the height of the tree at that point?
Answer:
A.
type A: Y= 15x +36
type B: Y= 10x + 48

A new homeowner needs to determine the length of his rectangular backyard before he goes to the store for fencing. He knows that the area of
the yard is 51 square meters and that the width is 5.2 meters longer than the length. Which equation could be solved to determine the
dimensions of the backyard, where the length is / and the width is w?
0=w/2+5.2w -51
0=/2+5.2/-51
4w +10.451
4/+10.4 = 51
Answer:
0=w^2-5.2w-51
Step-by-step explanation:
51=width x length
length=width-5.2
substitute for length
51=width x (width-5.2)
51=w^2-5.2w
0=w^2-5.2w-51

a) a train leaves westchester at 6.30. What time should it arrive at middlewich? b) Kate lives in Northton. She works in southam and starts works at 9am. What is the time of the latest train that she can catch to get to work on time? C) how long does the train take to travel from the westchester to east wick?
Answer:
a). 6:51
b). 6:30 am
c). 34 minutes
Step-by-step explanation:
a). Train leaves Westchester at 6:30.
From the arrival - departure table in column (2),
Arrival time of the train at middlewich = 6:51
b). Kate has to reach Southam before 9:00 am
Therefore, time of the latest train that she can catch to get to work on time is 6:30 am
By this train she can reach at 07:19 at Southam.
c). Duration of journey from Westchester to Eastwick = 06:34 - 06:00
= 00:34

PLEASE HELP! ITS A DECENTLY EASY QUESTION BUT I CANT FIGURE IT OUT!
Answer:
3,4 and 5 are correct........☺
Answer:
3,4,5
Step-by-step explanation:
To answer, we must go through all the expressions shown, solve them, and make sure that they are exactly like 3xy + 6yz.
1. We must distribute 3 to whatever is in the parentheses, but if you look, you can see that we have to multiply 3 by 6yz, which would come out to 18yz, and that is not in the original expression, so this one is FALSE
2. For this expression, we can rule it out because the first part of the expression would be 3xyz, and that is not a part of the original expression, this is one is FALSE
3. This expression, if you distribute the 3y, you get 3yx + 6zy, which is the same as the original expression, even if the variables are a bit jumbled, they all have the same value, so this one is TRUE
4. If you distribute y for this expression, you get y3x + y6z, which is the same as the original expression, because as I said before, the variables can be jumbled, but as long as all the values are there, we can safely say that this expression is TRUE
5. As you can see, this expression is the same as 4, so this one is also TRUE
Hope this helps :)

Find the slope of the line with f(6) = -2 and f(-4) = 3
Answer:
m=-1/2
Step-by-step explanation:
f(6)=-2 is (6,-2) and f(-4)=3 is (-4,3)
the equation for slope (m) is (y2-y1)/(x2-x1)
label the points:
x1=6
y2=-2
x2=-4
y2=3
now substitute into the equation:
m=(3--2)/(-4-6)
m=5/-10
m=-1/2
the slope is -1/2

Actually Welcome to the Concept of the Similarities.
Since here, first figure is a Triangle, hence similarity of a triangle is given by ratio of it sides and make them equate,
hence for,
1.) 16/12 = x/9 ===> 4/3 = x/9 ===> x = 9*4/3 ==> x = 36/3
hence the value of x is 12 , ===> x = 12 .
2.) here,in the case of a Reactangle the relation is such that, length = 2* breadth,
hence we apply the relation,
x = 2*4.5 ===> x = 9 units.
Write the equation of a line with an undefined slope that passes through the point (-6,3)
Answer:
x = -6
Step-by-step explanation:
A line with an undefined slope is vertical and is always represented by the equation x = a number. That number, whatever it may be, represents the x-value of all the points it intersects. Thus, take the x-value of the point (-6,3) and put it into the equation. So, the equation must be x = -6.
