Mathematics
1 answer:
xxTIMURxx [149]3 years ago
3 0

Answer:

b^2 - 6b - 55

Step-by-step explanation:

(b + 5)(b - 11)

Use FOIL

First

Outside

Inside

Last

F:  b * b = b^2

O:  b * -11 = -11b

I:  5 * b = 5b

L:  5 * -11 = -55

b^2 - 11b + 5b - 55

Combine like terms

-11b + 5b = -6b

b^2 - 6b - 55

What is the equation of the following line? Be sure to scroll down first to see
topjm [15]

Answer: (f)

Step-by-step explanation:

Given

Line that passes through (-\frac{1}{2},3) and (0,0)

Using two point form, equation of a line is given by

\Rightarrow \dfrac{y-y_1}{x-x_1}=\dfrac{y_2-y_1}{x_2-x_1}

Insert the values

\Rightarrow \dfrac{y-0}{x-0}=\dfrac{3-0}{-\frac{1}{2}-0}\\\\\Rightarrow \dfrac{y}{x}=-6\\\\\Rightarrow y=-6x

Thus, option (f) is correct

Which ordered pair would form a proportional relationship with the point graphed below? On a coordinate plane, a line with negat
avanturin [10]

Answer:

Answer:

(5, 20)  

Step-by-step explanation:

We can find the slope of the line

m = (y2-y1)/(x2-x1)

   = (40-0)/(10-0)

   = 40/10

   =4

Since the line goes through (0,0) the y intercept is 0

y = mx+b

y = 4x

Lets check the points  by substituting into the equation

40, 10)     10 = 4*40   10 =160  no

(–5, –10)    -10 = 4*-5    10 = -20   no

(5, 20)       20 = 4*5    20 = 20  yes

(–10, –20)    -20 = 4*-10    -20 = -40   no

Step-by-step explanation:

Which ordered pair would form a proportional relationship with the point graphed below? On a coordinate plane, a line with negative slope goes through points (negative 20, 10), (0, 0), and (20, negative 10). (10, –20) (–30, 20) (–10, 5) (35, –20)
