What is the value of s in the equation 3r = 10 + 5s, when r = 10
Bad White [126]
3r = 10 + 5s , <span>r = 10
plug in the value of "r" into the equation:
3(10) = 10 +5s
30 = 10 + 5s
subtract 10 from both sides:
20 = 5s
divide both sides by 5:
4 = s
s = 4</span>

What is the vertex of the quadratic function f(x) = (x – 8)(x – 2)?
LekaFEV [45]
Something funny is that the x value of the vertex lies directl in the middle of the x intercepts
so
we see the x intercepts or 0's at x=8 and 2
the average is x=5
so find f(5) to find the y value of the vertex
f(5)=(5-8)(5-2)
f(5)=(-3)(3)
f(5)=-9

vertex is at (5,-9)

the actual way the teacher wants is to expand then compltete the square to get into the form f(x)=a(x-h)^2+k where the vertex is (h,k)
but whatever


verrtex is at (5,-9)

Help i give 5 stars and a crown​
REY [17]

Answer:

See below.

Step-by-step explanation:

1a)

<u>Angles:</u>

  • 48, 90, 90, a.

<u>Add:</u>

  • 48 + 90
  • = 138 + 90
  • = 228

<u>Subtract:</u>

  • 360 - 228
  • = 132.

Angle a: 132.

1b)

To get angle h above 180°, <u>We need to add h + 164:</u>

  • h + 164
  • = 110 + 164
  • = 274.

h = 110.

This is how to get h over 180°.
