Answer:
6x²-25x-9
Step-by-step explanation:
(2x-9)(3x+1)
1) Distribute the 2x to 3x and 1:
6x²+2x
2) Distribute the -9 to 3x and 1
-27x-9
3) Combine both expressions:
6x²-25x-9
Answer:
50°
Step-by-step explanation:
Recall that an inscribed angle is half the arc length. Since Angle A measures 50°, this means that the arc length of BC (the intercepted arc) is 100°.
Arc BC is also representative of Angle D. In other words, the measure of angle D is half of 100°.
Angle D = 50°.
Step-by-step explanation:
Hey there!
<u>Note</u><u>:</u><u> </u><u>Use</u><u> </u><u>double</u><u> point</u><u> formula</u><u> for</u><u> finding</u><u> </u><u>the</u><u> eqaution</u><u> which</u><u> </u><u>pass</u><u>es</u><u> through</u><u> </u><u>two</u><u> </u><u>points</u><u>.</u>
Given;
The points are; (1,-3) and (3,1).

Therefore, the eqaution is y = 2x-5.
Alternative:
<u>Steps</u><u>:</u>
- Find slope using slope formula and use one point formula.
- Simplify in the form of y = mx+c form.
Formula:
- Slope = (y2-y1)/(x2-x1)
- One point formula= (y-y1)= m(x-x1)
The points are; (1,-3) and (3,1).
Now;
Slope= (1- (-3))/(3-1)
= (1+3)/2
= 2
Again;
Using one-point formula.
(y+3) = 2(x-1)
y+3= 2x-2
y = 2x -5
Therefore, the equation is y = 2x-5.
