Answer:
B. x ≥ 1
Step-by-step explanation:
Step 1: Subtract 6x from both sides
4x + 16 ≥ 20
Step 2: Subtract 16 from both sides
4x ≥ 4
Step 3: Divide both sides by 4
x ≥ 1
And we have our answer!
The answer is: (2x+3) (3x+1)
Answer:
x=1, y=-4. (1, -4).
Step-by-step explanation:
y=-7x+3
y=-x-3
-------------
-7x+3=-x-3
-7x-(-x)+3=-3
-7x+x=-3-3
-6x=-6
6x=6
x=6/6
x=1
y=-1-3=-4
Answer:
-6g
Step-by-step explanation:
First, we are given that the inscribed angle of arc CB which is angle D is equal to 65°. This is half of the measure of the arc which is equal to the measure of the central angle, ∠O.
m∠O = 2 (65°) = 130°
Also, the measure of the angles where the tangent lines and the radii meet are equal to 90°. The sum of the measures of the angle of a quadrilateral ACOB is equal to 360°.
m∠O + m∠C + m∠B + m∠A = 360°
Substituting the known values,
130° + 90° + 90° + m∠A = 360°
The value of m∠A is equal to 50°.
<em>Answer: 50°</em>
