x^2+9x+18=238
x=11
11+3=14
11+6=17
A jet ski that holds 10 gallons of gas
moves across a lake at a constant speed.
When it starts, it is 45 miles from the shore.
After 30 minutes, it is 30 miles from the
shore. Which function describes the jet ski's
distance from the shore?
A. y = x/2 + 45
B. y = - x/2+45
C. y = 2x – 30
D. y = -2x – 15
Answer:
Step-by-step explanation: the answer is b
angle A and angle B are vertical angles. If m_A = (7x – 6) and m B = (8x – 27), then find the measure of angle b
Answer:
A = B; 7x - 6° = 8x -27°; x = 21°. So B = 8·21° - 27° = 141°

Find 2a for a = 3 1/4. 23 1/4 6 1/4 6 1/2 5 1/2
Answer:
6 [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
you are adding 3 1/4 to 3 1/4 which is 6 2/4 or 6 1/2
or you can multiply 13/4 by 2 to get 26/4 or 13/2 which, again, is 6 1/2
Elise says, "If you subtract 18 from my number and multiply the difference by - 3, the result is
- 33." What is Elise's number?
Elise's number is 29.
If you think of multiplying a value by -3 to get -33, it would obviously be 11.
So in this case, you would want to add 18 to 11 to get Elise's number, which is 29. Subtracting 18 from 29 would get you back to the value of 11, which you can then multiply it by -3 again to get -33.
What is the value of x in the diagram below?

The value of x in the diagram is 7 (D) because 2 * 7 = 14 and 7 * 7 = 49.
The value of x in the given diagram will be 7.
What are similar triangles?Similar triangle are those which have two pairs of interior corresponding angles are equal.
We have,
Two triangles as shown in the given figure,
Now,
Both the given triangles have 90° corresponding angles and also the opposite angle of 90° of both triangles is equal.
So,
Using triangle similarity rule,
i.e.
Sides are in equal proportion,
i.e.
[tex]\frac{49}{x} =\frac{14}{2}[/tex]
⇒
14x = 49 × 2
14x = 98
[tex]x=\frac{98}{14}[/tex]
x = 7
Hence, we can say that the value of x in the given diagram will be 7.

A subset of values of the function g(x) is shown in the following table.
Answer:
Option (4)
Step-by-step explanation:
x g(x) Ist difference IInd difference Ratio
1 13 - - -
2 3 3 - 13 = -10 - [tex]\frac{3}{13}[/tex]
3 -3 -3 - 3 = -6 -6 - (-10) = 4 [tex]\frac{-3}{3}=-1[/tex]
4 -5 -5 - (-3) = -2 -2 - (-6) = 4 [tex]\frac{-5}{-3}=\frac{5}{3}[/tex]
5 -3 -3 - (-5) = 2 2 - (-2) = 4 [tex]\frac{-3}{-5}=\frac{3}{5}[/tex]
This table depicts,
1). Ist difference is not common
2). IInd difference is common
3). Ratio is not common
Therefore, this table represents a quadratic function because the second difference are all the same value.
Option (4) will be the answer.
Graph linear equations
Answer:
y = -3x-2
Step-by-step explanation:
Well, the linear equation of a line is: y = mx + b
Where m is the slope and b is your y-intercept
So, you can just plug the numbers into the equation
m = -3 and b = - 2
y = -3x - 2
