The amount of the tip is approximately $
$7.00
O $7.20
0 $7.25
$7.50
Step-by-step explanation:
-0.64=-0.06x divide both sides by -0.06
x=10.66667 oz---------------amount of pure water that must evaporate
CK
0.04(32)=0.06(21.33333)
1.28~1.28

<u><em>Answer:</em></u>
The missing term is 3x²
<u><em>Explanation:</em></u>
Addition and subtraction can only take place between like terms.
<u>For two terms to be like</u>, both the variable and its degree must be the same in both terms
<u>Now, consider the given terms:</u>
First term is 7x² has the variable x with degree 2
The resulting term is 10x² has the variable x with degree 2
This means that the missing term is ax²
We need to get the value of "a"
<u>This is done as follows:</u>
ax² + 7x² = 10x²
x²(a+7) = 10x²
a+7 = 10
a = 10-7
a = 3
Therefore, the missing term is 3x²
Hope this helps :)
Answer:
Step-by-step explanation:
[4 2] * -2 5 = [ 4*-2 + 2*7 4*5+2*-1]
7 -1
= [-8+14 20-2]
= [6 18]
Answer:
A.
Step-by-step explanation:
A quadratic function may only intercept the y-axis once. This is because the definition of a y-intercept tells us that it is the point where x = 0. If there are multiple points where x = 0, then the expression cannot be a function. As such, a quadratic function can only have one.
Choice B contradicts the previous statement.
Choice C is wrong because the x-intercept is the zero of the function. This is because at a given x-coordinate that touches the x-axis, the y-coordinate will be 'zero'.
Choice D is wrong because the y-intercept is where x = 0.
I hope this helps!
