Answer:
(3x - (3x - 5y))(3x + (3x - 5y))
Step-by-step explanation:
We use difference of squares to help factor.
Answer:
<h2>C. x = 6</h2>
Step-by-step explanation
since we have a right triangle then we can apply the Pythagorean theorem:
x² + 8² =10²
⇒ x² = 10² - 8²
⇒ x² = 36
⇒ x² = 6²
⇒ x = 6 (because x is positive)
Step-by-step explanation:
a)
For each value of x, we need to solve for y.
Our equation is x² -2. This means that we multiply x by itself ( x * x = x²), and then subtract that value by 2.
Here is a list of the unfilled answers:
x = -2:
-2²-2 = -2 * -2 -2 = 4-2 = 2. -2 * -2 = 4 because two negatives multiplied together makes a positive.
x=-1:
-1²-2 = 1 -2 = -1
x=1
1²-2 = 1-2= -1
x=3:
3²-2 = 9-2 = 7
b)
In this graph, the y represents the vertical part and x represents the horizontal. For each value of y, there is a horizontal line that can be drawn. For example, when y=0, the bolded horizontal line near the bottom of the graph represents that. We then need to find the points on the line representing x²-2 where it touches the horizontal line of y=0. This happens when x=-1.5 and x=1.5, as it is between the positive/negative 1 and 2 values of x
