I need to know if these two graphs are a function, is one a function? is two a function?
Question 7
Answer:
The graph in question 7 is a function.
Step-by-step explanation:
In order to check whether the graph in question 7 is a function or not, we need to draw a vertical line anywhere on the graph, and if does not hit the graph more than once, it is a function.
It is observable that the vertical line will always intersect the graph in question 7 at the only place.
From the graph, it is clear the green vertical line intersects the graph at the only place. Hence, the graph in question 7 is a function.
Therefore, the graph in question 7 is a function.
Question 8
Answer:
The graph in question 8 is not a function.
Step-by-step explanation:
In order to check whether the graph in question 8 is a function or not, we need to draw a vertical line anywhere on the graph, and if does not hit the graph more than once, it is a function.
It is observable that the vertical line intersects the graph in question 8 at more than one place.
From the graph, it is clear the green vertical line intersects the graph at x=-3 at more than one place. We can not have the same x values for the two output values in order to be a function. Hence, the graph in question 8 would NOT be a function.
Therefore, the graph in question 8 is not a function.

Which system of equations is satisfied by the solution shown in the graph?
Answer:
(-2, 8) does not satisfy any system of the equation. In other words, no system of the equations satisfies the solution as shown in the graph.
Thus, not a single given option of the system of the equations satisfies the solution as shown in the graph.
Step-by-step explanation:
We know that the point of intersection of two lines on a graph is the solution of the system of equations.
From the graph, it is clear that the two lines intersect at x=-2 and y=8.
Thus, the point of intersection of the two lines is (-2, 8)
Putting the (-2, 8) in the first system of equations
x+2y=10 and x-y = 6
-2+2(8)=10 and -2-8=6
14 = 10 and -10 = 6
L.H.S ≠ R.H.S and L.H.S ≠ R.H.S
L.H.S and R.H.S of both the system of equations are not equal, It means (-2, 8) does not satisfy the system of the equations x+2y=10 and x-y = 6.
Putting the (-2, 8) in the second system of equations
x+2y=6 and x-y = 10
-2+2(8)=6 and -2-8=10
14 = 6 and -10 = 10
L.H.S ≠ R.H.S and L.H.S ≠ R.H.S
L.H.S and R.H.S of both the system of equations are not equal, It means (-2, 8) does not satisfy the system of the equations x+2y=6 and x-y = 10.
Putting the (-2, 8) in the third system of equations
x+y=6 and x-y = 10
-2+8=6 and -2-8=10
6 = 6 and -10 = 10
L.H.S = R.H.S and L.H.S ≠ R.H.S
L.H.S and R.H.S of x-y = 10 is not equal, It means (-2, 8) does not satisfy the system of the equations x+y=6 and x-y = 10.
Putting the (-2, 8) in the second system of equations
x+y=6 and x-2y = 10
-2+8=6 and -2-2(8)=10
14 = 6 and -18 = 10
L.H.S ≠ R.H.S and L.H.S ≠ R.H.S
L.H.S and R.H.S of both the system of equations are not equal, It means (-2, 8) does not satisfy the system of the equations x+y=6 and x-2y = 10.
In a nutshell, (-2, 8) does not satisfy any system of the equation. In other words, no system of the equations satisfies the solution as shown in the graph.
Thus, not a single given option of the system of the equations satisfies the solution as shown in the graph.

Answer:
Slope-1/4 Y-intercept--2 Equation-y=1/4x+-2 and choose any point on the line.
Step-by-step explanation:
To find slope, you will have to make a slope triangle with two intersecting points. Divide h/v witch is 1/4. The y-intercept is just the point on the y-axis so that is -2. For the fourth question, just choose any coordinate on the oblique line.
Hope that helps!

At the beginning of the year, Sadie had $70 in savings and saved an additional $18 each week thereafter. Jack started the year with $90 and saved $14 every week. Let S S represent the amount of money Sadie has saved t t weeks after the beginning of the year and let J J represent the amount of money Jack has saved t t weeks after the beginning of the year. Write an equation for each situation, in terms of t , t, and determine the amount of money Sadie and Jack have saved in the week that they have the same amount of money saved.
Answer:
$160Step-by-step explanation:
Step one:
For Sadie
initial savings balance= $70
weekly savings = $18
Let S represent the amount of money Sadie has saved
and t the number of weeks after the beginning of the year
The total amount in savings after t weeks is
S=18t+70-------1
For Jack
initial savings balance= $90
weekly savings = $14
Let J represent the amount of money Jack has saved
and t the number of weeks after the beginning of the year
The total amount in savings after t weeks is
J=14t+90---------2
Step two
equation 1 and 2 to find t
18t+70=14t+90
18t-14t=90-70
4t=20
divide both sides by 4
t=20/4
t=5 weeks
so after 5 weeks Sadie and Jack will have the same amount of money
For Sadle t=5
S=18(5)+70-------1
S=90+70
S=$160
For Jack t=5
J=14(5)+90---------2
J=70+90
J=160
The two equations above shows that after 5 weeks their savings will be $160

There is a castle with a million dollars for anyone who can get to it first. The castle is surrounded by a moat that is square (4 equal sides) and the moat is 12ft wide at all areas. You have two 10' wooden planks, but no nails, rope, clothing or any other materials or means to put the planks together. Also, you cannot toss one to the other side, and lay one in on the shoreline and walk down into the moat and back up to the other side. think of the moat as charged with a bazillion volts of electricity. Can you get to the million dollars and the castle?
Answer:
12ft

4) The table below shows the price of paper plates at the grocery store. Find the unit price of
each brand, rounded to the nearest cent. Which is the best buy? Explain your reasoning.
Sturdy Plates 24 pack for $3.28
No Spill Plates 10 pack for $1.79
Compartment Plates 50 pack for $6.00
Answer:
Compartment plates is the best buy
Step-by-step explanation:
To find unit price, you can just divide the price by the number of plates
Sturdy plates: 3.28÷24= $0.14/plate
No spill plates: 1.79÷10 = $0.18/plate
Compartment plates: 6.00÷50 = $0.12/ plate
Out of all of the prices, $0.12 is the cheapest

Answer:
ok this triangle is an isosceles triangle because when you tell sit and look at the base sides that is 55° and be those are the base angles so if one is 55 the other one is also 55 So B is 55
Answer:
B=55°
Step-by-step explanation:
That is an isosceles triangle TS and US are the same size. So the 2 angles at the base (TU) will be the same. so b=55°

3. A geometric sequence g starts at 500 and has a growth factor of 0.6. Sketch a graph of g
showing the first 5 terms.
Answer:
Here you go! Sorry if its not in the correct format.
Hope this helps!
All five terms of GP are 500, 800, 1280, 2048, and 3276.8.
What is geometrical progression series?A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.
For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.
Given the first term 500
And it is growing by 0.6 factor
It means,
Second term = first term + 0.6 of first term
Second term = 500 + 0.6(500)
Second term = 500 + 300 = 800
And similarly, all three terms are 1280, 2048, and 3276.8.
Hence "All five terms of GP are 500, 800, 1280, 2048, and 3276.8".

Answer:
11/6 or 1.8333333333
Step-by-step explanation:
[tex]\frac{2x + 1}{6}[/tex] = [tex]\frac{7}{9}[/tex]
Cross Multiply:
7 x 6 = 42
9 (2x+1)
42 = 9(2x+1)
42 = 18x + 9
Then, isolate the variable. In order to do so, subtract 9 from both sides.
33 = 18x
Now, divide by 18 (to find x)
33/18 =

what is true about the number of sides in any regular polygon that has at least one line of symmetry passing through two vertices
Step-by-step explanation:
A regular n-sided polygon has n lines of symmetry. If n is odd, each line of symmetry passes through only one vertex. If n is even, half the lines pass through two vertices, and half pass through none.
So if a line passes through two vertices, the polygon must have an even number of sides.

Answer:
x=5
Step-by-step explanation:
Answer:
x = 5
Step-by-step explanation:
Original Equation:
2(x + 2) = 14
Use distributive property
2 · x = 2x
2 · 2 = 4
Your equation should look like this now:
2x + 4 = 14
Subtract 4 from both sides.
2x = 10
Divide both sides by 2
x = 5
