Answer:  B. 12

Step-by-step explanation:

f(x) = 3x2 – 7x + 2

f(- 1) = ?

f(-1)=3(-1)^2-7(-1)+2

     =3(1)+7+2

     =3+7+2

      =12

1. The diagram shown is two intersecting lines. The measure of <5is 47°.
Savatey [412]

The measure of ∠7 is 47°. Angle 7 is a vertical angle to angle 5

Suppose the measure of ∠6 is represented represented by (2x - 5), the equation that can be use to solve for x is 42 + 2x = 180

The value of x is 69

<h3>Vertical opposite angles</h3>

Vertically opposite angles are angles that are opposite one another at a specific vertex and are created by two straight intersecting lines.

Vertical opposite angles are congruent. Therefore,

a. ∠5 ≅ ∠7 (vertical angles)

Therefore, angles 5 and 7 are congruent angles.

∠7 = 47°

b. Suppose ∠6 = 2x - 5 . let's find x

Therefore,

∠5 + ∠6 = 180(angle on a straight line)

The equation to solve the above is as follows:

47 + 2x - 5 = 180

42 + 2x = 180

2x = 180 - 42

2x = 138

x = 138 / 2

x = 69

You are at a restaurant and your bill comes to $31.18. The sales tax is 6% and you give the waitress a 20 percent tip on the tot
Vanyuwa [196]

Answer:

$ 0.34   or 34 cents

Step-by-step explanation:

Bill amount = $31.18

sales tax = 6%  of $31.18

             =  0.06 ($31.18)

             = $1.8708

Bill with tax = $31.18+$1.8708

                  = $33.0508

value of tip = 20% of 33.0508

                   =  6.61016

Total  payment  = 33.0508+ 6.61016

                           = $39.66096

                          or $39.66

                         We get change of $40 - $39.66

                                                = $ 0.34        

We shall get back in  cents that will be 34   cents
