If you want 2 numbers, you have: 1+10, 2+9, 3+8, and so on. If you need 3 numbers you have 1+1+9, 1+2+8, 2+2+7, and so on.
Answer:
A
Step-by-step explanation:
1) y = -x + 6
2) y = x - 6
The line with a positive slope (2) crosses the y-axis (vertical line) at - 6 (positive slope line goes uphill)
The line with the negative slope (1) crosses the y-axis at 6. (Negative slope goes downhill)
We will expand the factored form of (x − 9)(x − 1) into the same form as x² − 10x + 9 to show they are equal.
Distribute and multipy out:
(x − 9)(x − 1)
x * x = x²
x * -1 = -x
x * -9 = -9x
-9 * -1 = 9
Add together:
x² + -x + -9x + 9
x² − 10x + 9
Use the Reflexive property:
x² − 10x + 9 = x² − 10x + 9 ✓
Answer:
<u>x = 120°, y = 20°</u>
Step-by-step explanation:
Let's recall that the four interior angles in any rhombus must have a sum of 360 degrees. In addition, the opposite interior angles must be equivalent, and the adjacent angles have a sum of 180 degrees.
∠ ABC and ∠ ADC are opposite interior angles, so they must have equivalent measurements, therefore x = 120 degrees.
To find the value of y, we use this equation because the interior angles of the Δ ADC add up to 180:
y = 180 - 120 - 40
y = 180 - 160
y = 20 degrees ⇒ z = 40 degrees
