What is the angles mSRW?

Scilla [17]

Answer:

126°

Step-by-step explanation:

(2x +18)° = (3x)°

2x + 18 = 3x

18 = 3x - 2x

18 = x

therefore, (3x)° = (3*18)°= (54)°

$m\angle SRW + (3x)\degree = 180\degree \\m\angle SRW + 54\degree = 180\degree \\m\angle SRW = 180\degree - 54\degree \\\huge\red{\boxed{m\angle SRW = 126\degree}}$

Find the x-intercepts of the parabola with vertex (-4,2) and y-intercept (0,-30). Write your answer in this form: (x1, y1),(x2,

Ainat [17]

Vertex form of a parabola
<span>y = a (x - h)^2 + k </span>

<span>where (h, k) is the vertex </span>
Substituting the values of h and k.
we get,

<span>y = a(x + 4)^2 + 2 </span>

<span>substituting in the point (0, -30) for x and y
</span><span>-30 = a (0 + 4)^2 + 2

</span>solve for a,

<span>-30 = 16 a + 2 </span>
<span>-32 = 16 a </span>
<span>-2 = a </span>

<span>y = -2(x + 4)^2 + 2 </span>

<span>Put y = 0 </span>

<span>-2 x^2 - 16 x - 30 = 0 </span>
<span>-2(x^2 + 8 x + 15) = 0 </span>
<span>x^2 + 8 x + 15 = 0 </span>
<span>(x + 3)(x + 5) = 0 </span>

<span>x = -3
x = -5</span>
