93 ÷ 1000
= 9.3 ÷ 100
= 0.93 ÷ 10
= 0.093 ÷ 1
= 0.093
Y - 4 x = 7 - x²
y = - x ² + 4 x + 7 ( this is a quadratic function )
x = - b / 2 a, where: a = - 1 and b = 4
x = - 4 / ( - 2 ) = 2
Answer:
The axis of symmetry for the graph is x = 2
To solve this problem you must follow the proccedure below:
1. You have the following information:
<span>
- April put gasoline in 4 of her 5 gallons cans.
- She put gasoline in 6 of her 2 gallons cans.
2. Let's call "x" to the number of gallons of gas that she bought. Therefore, you have:
x=(4x5 gallons)+(6x2 gallons)
x=20 gallons+12 gallons
3. Finally, the result is:
x=32 gallons
</span><span>
How many gallons of gas did she buy?
</span><span>
The answer is: 32 gallons</span>
Good evening
Answer:
<h2>measure of Angle 1 = 81°</h2><h2>Measure of angle 2 = 9°</h2>
Step-by-step explanation:
we need to solve this system
x + y = 90 (1)
x = y + 72 (2)
If we substitute x by y+72 into the equation (1) we will get
(y+72) + y = 90 ⇔ 2y + 72 = 90 ⇔ 2y = 90 - 72 = 18 ⇔ y = 9
then x = 90 - 9 = 81
