Please find the fully simplified intercept form!!!! Will mark Brianliest !!!!!!!!!!!
photoshop1234 [79]

Answer:

  • y = -1/3x  - 8

Step-by-step explanation:

<u>Slope intercept form:</u>

  • y = mx + b

<u>Use two points from the graph:</u>

  • (0, -8) and (3, -9)

<u>The first point is the y-intercept: </u>

  • b = -8

<u>Find the slope using the slope formula:</u>

  • m = (y2 - y1)/(x2 - x1)
  • m = (-9 - (-8))/3 = -1/3

<u>The equation is:</u>

  • y = -1/3x  - 8

Solve for a: a(a-3) =100
marissa [1.9K]
a(a-3) =100\\&#10;a^2-3a-100=0\\&#10;\Delta=(-3)^2-4\cdot1\cdot(-100)=9+400=409\\&#10;\sqrt{\Delta}=\sqr{409}\\&#10;a_1=\dfrac{-(-3)-\sqrt{409}}{2\cdot1}=\dfrac{3-\sqrt{409}}{2}\\&#10;a_2=\dfrac{-(-3)+\sqrt{409}}{2\cdot1}=\dfrac{3+\sqrt{409}}{2}

Find the values of m and b that make the following function differentiable.
Sonbull [250]
The derivative of f(x) at x=3 is 2x=6 approaching from the left side (apply power rule to y=x^2). The derivative of f(x) at x=3 is m approaching from the right side. In order for the function to be differentiable, the limit of derivative at x=3 must be the same approaching from both sides, so m=6. Then, x^2=mx+b at x=3, plug in m=6, 9=18+b, so b=-9.

Who had a head start, and how many miles was the head start? Rita had a 28-mile head start. Roger had a 26-mile head start. Roge
serg [7]

Complete question is;

Roger and Rita each drive at a constant speed between Phoenix and San Diego. Each driver’s distance for the same section of the trip is displayed below. Who had a head start, and how many miles was the head start?

A) Rita had a 28-mile head start.

B) Roger had a 26-mile head start.

C) Roger had a 25-mile head start.

D) Rita had a 22-mile head start.

Answer:

A) Rita had a 28-mile head start.

Step-by-step explanation:

Let's assume that Roger travelled a distance of 60 miles

And that;

Rita travelled a distance of 32 miles

We are told that they travelled between Phoenix and San Diego.

Thus, it means that if they have different distances but covered same section of the trip, it means the one with higher distance started before the section of the trip.

Thus, it means that Rita had a head start of Roger since she covered only 32 miles.

Thus;

Rita had a head start of; 60 - 32 = 28 miles
