qaws [65]4 years ago
6 0

Answer:

Step-by-step explanation:

Prove that

sec(x) - sin(x)tan(x)=cosx

sec(x)=1/cos(x) tan(x)=sin(x)/cos(x)

1/cos(x) - sin(x) x sin(x)/cos(x)

(1-sin(x) x sin(x))/cos(x)

(1-sin^2(x))/cos(x) 1-sin^2(x)=cos^2(x)

Cos^2(x)/cos(x)

(Cos(x) x cos(x))/cos(x)

cos(x) proved

WRITE THE EQUATION BELOW IN SLOPE-INTERCEPT FORM;<br><br> 14x=6Y-12
valentinak56 [21]

The sllope-intercept form:

y=mx+b


6y-12=14x          <em>add 12 to both sides</em>

6y=14x+12      <em>divide both sides by 6</em>

y=\dfrac{14}{6}x+\dfrac{12}{6}\\\\\boxed{y=\dfrac{7}{3}x+2}

What is the vertex of the quadratic function f(x)=(x-8)(x-2)
stich3 [128]
F(x)=(x−8)(x−2)

y=(x−5)2−9
(Pretend the 2 is an exponent)

Use the vertex form, y=a(x−h)2+ky=a(x-2+k, to determine the values of a,h, and k.

a=1
h=5
k=-9

Find the vertex (h, k).
(5, -9)
