Answer:
x= -1, y= 6
Step-by-step explanation:
9x + 7y =33---a
-6x = y---b
Put b into a,
9x + 7(-6x) = 33
9x - 42x = 33
-33x = 33
x = -1----c
put c into b,
-6(-1) = y
y=6
Answer:
The answer is (-1, -6)
Step-by-step explanation:
To get y by itself, you switch sides of the Y and the -6x
9x+7y=33
y= -6x
You then put the -6x where the y is
9x+ 7(-6x) = 33
9x -42x =33 9 -42 = -33
-33x = 33
It's now a one-step equation
x= -1
Now you put the x value (-1) where the x is in y= 6x
y= 6 (-1) y=-6

Answer:
The measure of the outside angle is the sum of the two inside angles:
68+52=120
Or you could do it the long way and find the third angle inside the triangle then do 180 minus that but this is easier.
Step-by-step explanation:
An airplane is flying in the direction of 30 degrees South of East at 500 mph. A wind is blowing in the direction of 45 degrees North of East at 55 mph. Find the direction angle of the airplane’s path, adjusted for the wind.
Answer:
B
Step-by-step explanation:
The angle of the airplane’s path is = [tex](\frac{250\sqrt{2}+55}{\sqrt{2}} )[/tex]î +[tex](\frac{250\sqrt{6}-55 }{2})[/tex]ĵ
what is vector?A vector is defined as a quantity which has two independent properties magnitude and direction.
î & ĵ denote two unit vectors along East & North directions respectively.
V1 denotes velocity vector direction of airplan of 30 degrees South of East at 500 mph
V2 denotes velocity vector wind the direction of 45 degrees North of East at 55 mph
V denotes the actual velocity vector of the given plane.
Hence from above data we get following descriptions,
V1 = 500.(sin 30°).î + 450.(cos 30°).ĵ
= 500.(1/2).î + 500(√3/2.ĵ
= 250î + 250√3ĵ
V2 = 55(sin 45°).î - 55(cos 45°).ĵ
= 55[1/√2].î - 55[1/√2]ĵ
V = V1 + V2
= 250î + 250√3ĵ +55[1/√2].î - 55[1/√2]ĵ
= 250î +55[1/√2].î + 250√3ĵ - 55[1/√2]ĵ
= [tex](\frac{250\sqrt{2}+55}{\sqrt{2}} )[/tex]î +[tex](\frac{250\sqrt{6}-55 }{2})[/tex]ĵ
Hence the angle of the airplane’s path is = [tex](\frac{250\sqrt{2}+55}{\sqrt{2}} )[/tex]î +[tex](\frac{250\sqrt{6}-55 }{2})[/tex]ĵ

1. f(x) = x^2 + 2
It is a quadratic function as in the format of y = ax^2 + bx + c2. f(x) = 2x - 10
It is linear function, not quadratic3. It is linear function as y- is an arithmetic sequence

The data represents the number of cars on a single day.
Find the relative frequency;
It is the number of times an event occurs.
Here the time frame is within a day;
Relative frequency = [tex]\frac{number of cars + number of vans + others}{number of days}[/tex]
Relative frequency = 60 + 21 + 3 = 84vehicles per day
ii.
Number of vans in a week;
Number vans in a week = 21van per day x 7 days = 147vans

Answer:
Parallel line - y=6x+9
Perpendicular line - y=-1/6x +4
Step-by-step explanation:
Parallel lines have a slope that is equal to the origninal equation. You use the y-y1=m(x-x1) equation. In this case, your y1 is 3 and your x1 is -1. Plug these into the equation along with your slope of 6.
y-y1=m(x-x1)
y-3=6(x-(-1))
y-3=6(x+1)
y-3=6x+6 - Distribute
+3 +3 - Add 3 to both sides
y=6x+9
For perpendicular lines, the slope is the negative reciprocal of the given slope. In this case, the slope is -1/6. Your y1 is 4 and your x1 is 0.
y-y1=m(x-x1)
[tex]y - 4 = - \frac{1}{6} (x - 0)[/tex]
Distribute:
[tex]y - 4 = - \frac{1}{6} x[/tex]
+4 +4
Add 4 to both sides:
[tex]y = - \frac{1}{6} x + 4[/tex]

Bernardo is converting a fraction, StartFraction a Over b EndFraction, to a percent. Both a and b are whole numbers and not equal to zero. Which expression represents the percent?
Answer:
[tex]Percent = \frac{100a}{b}\%[/tex]
Step-by-step explanation:
Given
[tex]\frac{a}{b}[/tex]
Required
Convert to fraction
To do this, we simply multiply the fraction by 100%
This gives:
[tex]Percent = \frac{a}{b} * 100\%[/tex]
[tex]Percent = \frac{a * 100}{b}\%[/tex]
[tex]Percent = \frac{100a}{b}\%[/tex]
The expression cannot be further simplified.
Take for instance the fraction is: [tex]\frac{2}{5}[/tex]
Using the same analysis, the percentage would be:
[tex]Percent = \frac{2}{5} * 100\%[/tex]
[tex]Percent = \frac{2 * 100}{5}\%[/tex]
[tex]Percent = \frac{200}{5}\%[/tex]
[tex]Percent = 40\%[/tex]
