Answer:
a) y = -7x +1
Step-by-step explanation:
Slope-intercept form is ...
y = mx + b
The other forms shown are various ways this can be rearranged, but they are not slope-intercept form.
Answer:
x = 132°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
A hexagon has 6 sides, thus n = 6
sum = 180° × 4 = 720°
Sum the given interior angles and equate to 720
x + 108 + 113 + 132 + 75 + 160 = 720, that is
x + 588 = 720 ( subtract 588 from both sides )
x = 132°
I believe its 4/5 because when you isolate y, you have to divide 5 and 4 but you Can just leave it in its decimal form.
Answer:
16.2
Step-by-step explanation:
A trick to remember for right triangles is SOH-CAH-TOA:
Sine = Opposite / Hypotenuse
Cosine = Adjacent / Hypotenuse
Tangent = Opposite / Adjacent
Here, we have the side adjacent to the angle and the hypotenuse. So we should use cosine.
cos 22° = 15 / x
x = 15 / cos 22°
x ≈ 16.2
