Answer:
So find the what?
Step-by-step explanation:
9514 1404 393
Answer:
- ∠BCA = 30°
- ∠FHC = 125°
- ∠A = 45°
- ∠GBC = 75°
- arc EBC = 260°
Step-by-step explanation:
Angle BCA intercepts arc FB, so is half its measure: 60°/2 = 30°.
Angle FHC is half the sum of the angles intercepted by its chords: (60°+150°+40°)/2 = 125°.
Angle A is half the difference of the arcs it intersects: (150° -60°)/2 = 45°.
Angle GBC is half the measure of the arc it intercepts: 150°/2 = 75°.
arc EBC is the sum of arcs EF, FB, and BC: 50° +60° +150° = 260°.
Answer:
It's the the 4th one. 6.3.3
f(x) = 2(x^2 + 14x + ) - 5 2 is taken out of first 2 terms.
f(x) = 2(x^2 + 14x + (14/2)^2 ) - 5 - 2(14/2)^2
<em><u>2 steps </u></em>
- Inside the brackets: Linear term's coefficient (14) divided by 2 and squared
- Outside the brackets: (14/2)^2 multiplied by 2 and subtract so that there is no change in the value of the quadratic.
f(x) = 2*(x + 7)^2 - 103
The graph is of the original quadratic.
<em>Answer:</em>
<em>For the first question the answer is : x = -10</em>
<em>And for the second question the answer is : x = 4</em>
<em>Step-by-step explanation:</em>
<em>For the first Equation :</em>
<em> 5(3x+2)-2 = -2(1-7x)</em>
<em> 15x +10-2 = -2 +14x</em>
<em> 15x + 8 = -2 + 14x</em>
<em>15x + 8 - 14x = -2 + 14x - 14x</em>
<em> x + 8 = -2</em>
<em> x+8-8 = -2 -8</em>
<em> x = -10</em>
<em>Answer : x = -10</em>
<em />
<em>For the second Equation :</em>
<em> 3x+2 = 14</em>
<em> 3x+2-2 = 14-2</em>
<em> 3x = 12</em>
<em> 3x/x = 12/3</em>
<em> x = 4</em>
<em>Answer : x = 4</em>
