To solve for <em>x</em>, we must first isolate the term containing <em>x</em> which in this problem is 5x.
Since 10 is being added to 5x, we subtract 10 from both sides of the equation to isolate the 5x.
On the left, the +10 and -10 cancel out and on the right, 20 - 10 is 10 and we have 5x = 10.
Now we can finish things off by just dividing both sides of the equation by 5. On the left the 5's cancel and on the right, 10 divided by 5 is 2 so <em>x = 2</em>.
Answer:
b) EF = GF , as both of them are at equal distance from the center
Step-by-step explanation:
Here we are given a ΔEFG inscribed in a circle. We have to determine whether EF = Gf and why ?
Here we see that the center is A
And EF and GF forms the chords of this circle.
The distance of these chords from the center is given as AD and DH . It is also given that both are equal.
The property of a circle says that
When chords are drawn at equal distance from the center , the chords are equal to each other. Hence we have EF and GF equal to each other.
Answer:
The measurement of the ∠7 is 132°
Step-by-step explanation:
we are given that angle 3 and angle 7 are consecutive interior angles. The sum of consecutive interior angles is always 180°.
Hence
∠3+∠7=180°
48°+∠7=180°
Subtracting 48° from each side
∠7=132°
Plug in -3 for x
f(-3) = 8(2^-3)
2^-3 = 1/2^3 = 1/6
f(-3) = 8(1/6)
f(-3) = 8/6
Simplify. Divide 2 from both numerator and denominator
f(-3) = (8/6)/(2/2)
f(-3) = 4/3
f(-3) = 4/3 , or 1 1/3
hope this helps
