Answer:
y <= 7/9
Step-by-step explanation:
1. Take -2/9 to the other side by adding.
2. You get y <= 7/9
3. Hopefully you know how to plot inequalities on a graph!
- use the FILLED IN dot (because it <u>includes 7/9</u>) and the arrow FACING LEFTWARDS (because it is <u>less than/equal to 7/9</u>) put the point on 7/9 and make the arrow go leftwards.
Good Luck on your test!!
Answer:
y = √(3² + 3²)
9 = √(5² + x²)
Step-by-step explanation:
Diagram 1:
Hypotenuse = y
Opposite = 3
Adjacent = 3
y² = 3² + 3²
y = √(3² + 3²)
y = √(9 + 9)
y = √18
Diagram 2:
Hypotenuse ² = known leg² + unknown leg²
Hypotenuse = 9
Known leg = 5
Unknown leg = x
9² = 5² + x²
9 = √(5² + x²)
9² = 5² + x²
9² - 5² = x²
x² = 81 - 25
x = √ 56
Answer:
B (-1 , -4)
Step-by-step explanation:
A (3 , 4)
M (1 , 0)
M is the midpoint of segment AB means :
Then
Then
Then
Given that a car averages 32 miles per gallon of gasoline.
That means in 1 gallon of gasoline, car will travel 32 miles.
Now we have to find the distance travelled by car in one fluid ounce of gasoline.
We know that 1 US liquid gallon = 128 US fluid ounce
So that means car travels 32 miles in 128 fluid ounce of gasoline
So to find the distance travelled by car in one fluid ounce of gasoline, we just need to divide 32 miles by 128
Hence answer will be 32/128 or 0.25 miles.
7x+2=23
Move 2 to the other side
7x=23-2
7x=21
To isolate the x divide both sides by 7
x=3
To check plug the value of x back in
7(3)+2=23
21+2=23
23=23
