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 =
1.8333333 or 11/6
Solve the equation.

apply the Pythagorean Theorem
Answer:
Tom wont need a longer ladder.
Step-by-step explanation:
Answer:
No the ladder is long enough.
Step-by-step explanation:
30x30=900
4x4=16
Sq. Root of (900+16)= 30.27ft distance from the ground to the roof, 4 ft away from the house.
Which of the following statements about the graph of y= 34x −1 are true? Select all that apply.
A.) The slope of the line is 3/4.
B.) The slope of the line is 1.
C.) The line intersects the point (0,3/4).
D.) The line intersects the point (0, -1).
E.) The y-intercept is -1.
F.) The y-intercept is 3/4.
9514 1404 393
Answer:
A, D, E
Step-by-step explanation:
Assuming your graph is of the equation ...
y = 3/4x -1
The slope is 3/4. The line intersects (0, -1). The y-intercept is -1.
A, D, E are true
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

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°
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.

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
the way i did it was if it was on the bottom (y) i did 2.5 times the number. if on the top (x) i did the number divided by 2.5. 2.5 was the rate of change (is that the word i think it is but if it isnt just blame me im sorry).

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
