Answer:
y < 5
Step by step:Step 1: Subtract 5y from both sides.
7y+2−5y<5y+12−5y
2y+2<12
Step 2: Subtract 2 from both sides.
2y+2−2<12−2
2y<10
Step 3: Divide both sides by 2.
[tex]\frac{2y}{2}[/tex] < [tex]\frac{10}{2}[/tex]
= y < 5
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

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.

it's about proportion and stuff but I'm confused on this one can someone please explain?
Answer:
the one clue you have is "30,12" on the left. try to understand how they relate to each other. maybe how many times 12 goes into 30. or maybe how many times it goes into 32 with no decimal so what number do you have to add (sometimes work doesnt mean it like that so that might be wrong). but if you want the answers, they are:
35/5/15/30
14/2/6/12

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 =

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

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".

Help me please
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
