Answer 2

9514 1404 393

Answer:

  -24

Step-by-step explanation:

We can simplify this to ...

  b^2 +3(b -b^2) -2a

  = b^2 +3b -3b^2 -2a

  = -2b^2 +3b -2a . . . . . . . simplified form

This can be made easier for evaluation by factoring out b.

  = (-2b +3)b -2a

Using the given values, this is

  = (-2(4) +3)(4) -2(2)

  = (-5)(4) -4

  = -24 . . . . value of the expression

The points (-3, -3) and (5, r) lie on a line with slope 3/2
Find the missing coordinate r.

Answers

Answer:

The missing coordinate [tex]r[/tex] is 9.

Step-by-step explanation:

Given the points [tex]P(x,y) = (-3,-3)[/tex] and [tex]Q(x,y) = (5,r)[/tex], the slope of a line passing the two points ([tex]m_{PQ}[/tex]) is determined by equation of secant line:

[tex]m_{PQ} = \frac{y_{Q}-y_{P}}{x_{Q}-x_{P}}[/tex] (1)

[tex]m_{PQ} = \frac{r-(-3)}{5-(-3)}[/tex]

If we know that [tex]m_{PQ} = \frac{3}{2}[/tex], then the value of [tex]r[/tex] is:

[tex]\frac{3}{2} = \frac{r+3}{8}[/tex]

[tex]12 = r + 3[/tex]

[tex]r = 9[/tex]

The missing coordinate [tex]r[/tex] is 9.

the answer for it is 58/35

Answer:

[tex]\frac{58}{35}[/tex] is the answer.

Step-by-step explanation:

1) Use this rule: [tex]\frac{a}{b} * c = \frac{ac}{b}[/tex]

[tex]\frac{4}{5} + \frac{3*2}{7}[/tex]

2) Simplify 3 * 2 to 6.

[tex]\frac{4}{5} + \frac{6}{7}[/tex]

3) Simplify.

[tex]\frac{58}{35}[/tex]

Therefor, the answer is 58/35 and if you need it on decimal form it would be, 1.657143.

b + a +  87 -87 = 180-87

b + a  = 180-87

b + a  = 93

b = 93 -a
