Answer: -rad7, +rad7

Explanation:
- Divide the equation by 6 (x^2-7=0)
- Add 7 (x^2=7)

For questions 8 – 10, answer the questions about tangent-tangent angles.

Answer:

m(arc ZWY) = 305°

Step-by-step explanation:

8). Formula for the angle formed outside the circle by the intersection of two tangents or two secants is,

Angle formed by two tangents = $\frac{1}{2}(\text{Difference of intercepted arcs})$

= $\frac{1}{2}(220-140)$

= $\frac{1}{2}(80)$

= 40°

9). Following the same rule as above,

Angle formed between two tangents = $\frac{1}{2}(\text{Difference of intercepted arcs})$

125 = $\frac{1}{2}[m(\text{major arc})-m(\text{minor arc})]$

250 = $[m(\text{arc ZWY})-m(\text{arc ZY})]$

250 = m(arc ZWY) - 55

m(arc ZWY) = 305°

Therefore, measure of arc ZWY = 305° will be the answer.

10). m(arc BAC) = $\frac{1}{2}([m(\text{arc BDC})-m(\text{arc BC})])$

= $\frac{1}{2}(254-106)$

= $\frac{148}{2}$

= 74°

What is the slope of the line that passes through the points (-2, -3), and (5, 4)?

fomenos

Hi!

<h3>To find the slope, use this formula</h3>

$\frac{y2-y1}{x2-x1}$

<h3>Put in the values</h3>

$\frac{4-(-3)}{5-(-2)}=\frac{7}{7}simplify=1$

<h2>The slope is 1 </h2>

Hope this helps! :)
