Answer:

  • y = 2x + 3
  • y = -6x
  • y = -x + 2
  • y = 2x - 7

Step-by-step explanation:

<u>Slope-intercept form:</u>

  • y = mx + b

<em>Hint. if we have x = 0, then the y-coordinate is the same as b</em>

<u>Slope</u>

  • m = (y2 - y1)/(x2-x1)

33.

  • m = (9 -(-3))/(3 - (-3)) = 12/6 = 2
  • b = 3 as per table (0, 3)
  • y = 2x + 3

34.

  • m = (0-12)/(0 - (-2)) = -12/2 = -6
  • b = 0, as per table (0, 0)
  • y = -6x

35.

  • m = (2 - (-2))/(0 - 4) = 4/-4 = -1
  • b = 2, as per table (0, 2)
  • y = -x + 2

36.

  • m = (-5 - (-1))/ (1 -3) = -4/-2 = 2

Using point (3, -1)

  • -1 = 2*3 + b
  • b= -1 - 6= - 7
  • y = 2x - 7

Points F(3, 3), K(6, 5), J(8, 2) and L(5, 0) lie in a coordinate plane. Which lines are perpendicular?
Romashka-Z-Leto [24]
To determine if a line is perpendicular to another, you must first determine the slope...
m = y1-y2/x1-x2
m of FK = 3-5/3-6 = -2/-3 = 2/3
m of FJ = 3-2/3-8 = 1/-5
m of FL = 3-0/3-5 = 3/-2
m of KJ = 5-2/6-8 = 3/-2
m of KL = 5-0/6-5 = 5
m of JL = 2-0/ 8-5 = 2/3

In order for two lines to be perpendicular, their slopes must be opposite reciprocals...
FK is perpendicular to FL
FK is perpendicular to KJ
JL is perpendicular to FL
JL is perpendicular to KJ
FJ is perpendicular to KL

Use long division to find the quotient​ Q(x) and the remainder​ R(x) when​ P(x) is divided by​ d(x) and express​ P(x) in the for
lilavasa [31]

Answer:

P(x)=(x+9)(x^2-7x+52)+3

Step-by-step explanation:

We are given that

P(x)=x^3+2x^2-11x+471

d(x)=x+9

We have to find the value of Q(x) and Remainder R(x).

Quotient, Q(x)=x^2-7x+52

Remainder,R(x)=3

We know that

Dividend=Divisor\times Quotient+Remainder

P(x)=(x+9)(x^2-7x+52)+3

Determine the equation of the graph.
ruslelena [56]

Answer: C

y=-5cos(x) is the graphed equation. Cos(x) starts at (0,0) and one period is 2pi or 6.28 and by cos(x) multiplied by -5 starts the cosine wave at (0,-5) and thus corresponds to the graphed equation shown.

Any questions please feel free to ask. Thanks

What is 12.55 to the nearest 1 decimal place
yaroslaw [1]
One decimal place means one place after the decimal point, therefore you should round appropriately to get to one place after the decimal point.

The answer would therefore be 12.6 <span />
