-3(3)-8

-9-8=-17

Answer:

f(3) = - 17

Step-by-step explanation:

To evaluate f(3), substitute x = 3 into f(x) , that is

Answer:

23[tex]\frac{1}{3}[/tex]m/s

Step-by-step explanation:

We can change the km to m first. 1km = 1000m.

84km/h = 84 000m/h

Then, we can change the h to s. 1h = 3600s.

84 000m/h = 23[tex]\frac{1}{3}[/tex]m/s

Answer:

ounces

Step-by-step explanation:

moat likely ounces because of the size of the ring

The correct answer from the choices listed above is the first option, ounces.

Weight is the measure of the force of gravity acting on a body.

The weight of a gold ring most likely is expressed in ounces. The weight of gold is measured in troy ounces (1 troy ounce = 31.1034768 grams), but its purity, or "fineness" has been measured in a few different ways: "parts fine," "% gold", and carats.

Hence, the answer is ounces.

Answer:

$0.85

Step-by-step explanation:

Given that,

Price of 10 tacos for $8.50

We need to find the charge for 1 taco.

We can find it using the unitary method.

10 tacos = $8.50

1 taco = [tex]\dfrac{8.5}{10}[/tex] = $0.85

Hence, restaurant A charge $0.85 for 1 taco.

Answer:

3 < x < 7

Step-by-step explanation:

From the diagram; |AB| = |AC|

The length AB is calculated as;

[tex]Sin\ 52^o = \frac{|BD|}{|AB|} \\\\|AB| = \frac{|BD|}{Sin\ 52^o} \\\\|AB| = \frac{12}{Sin\ 52^o} \\\\|AB| =15.228 \ m[/tex]

The length CD is calculated as;

[tex]Sin \ 31^o = \frac{|CD|}{|AC|} \\\\|CD| = |AC| \ \times \ Sin \ 31^o \\\\|CD| = 15.228 \ \times \ 0.515\\\\|CD| = 7.84[/tex]

|CD| = 2x - 6

2x - 6  = 7.84

2x = 7.84 + 6

2x = 13.84

x = 13.84 / 2

x = 6.92

x ≅ 7

Thus, 3 < x < 7

Answer:

-15%

Step-by-step explanation:

percentage change is calculated by

(new price - old price) / old price

(850 - 1000) / 1000

please give thanks by hitting heart button! :)

Answer:

15%

Step-by-step explanation:

1. Subtract the sale price from the normal price.

$1000 - $850 = $150.

2. Divide this amount by the original price.

$150/$1000 = 0.15

3. Multiply by 100 to get the %.

0.15 x 100 = 15%

Answer:

12

Step-by-step explanation:

I am assuming you are asking for f(x)=x^2-3x+8? You plug (-1) in for all portions of x. This means you get (-1)^2-3(-1)+8. (-1)^2 is simply 1 because -1 x -1=1. 3*-1 is -3. This makes the equation 1 - (-3) + 8. The middle section simplifies down to +3 making it 1+3+8, or 12.

Answer:

so the equation would be

u+t+h=12

lets break it down

we know that t is equal to

h+ 2

and we know that u is equal to

h+t

okay so first we need to focus on finding one of the units then we can find the next ones

so lets find h first,

with the equations we found h is involved in all of them so we can use them in the equation that equals 12 ( ill make it easier for you and make all of the units equal to their equation including h)

u= h+t

h+2=t

t= h+2

h=h

u= h+h+2

so lets put it together

(h+h+2)+(h)+(h+2)=12

4h+4=12

    -4  -4

4h=8

/4   /4

h=2

okay now using our other equations lets find t and u

h+2=t

2+2=t

4=t

h+t=u

2+4=u

6=u

now lets check our answers

u+t+h

6+4+2=12

10+2=12

12=12

so now that we know the values lets put them into their places in the number

uth

u=6

t=4

h=2

642 is your number

Answer:

Joe worked 3 hours overtime.

Step-by-step explanation:

Let t = number of hours overworked

425 + 20 × t = 485

425 + 20t = 485

20t = 485 - 425

     = 60

[tex]\frac{20t}{20} = \frac{60}{20}[/tex]

t = 3

Answer:

what

Step-by-step explanation:

The Slope of line (1, 1) and (3, 9) is 4.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the

change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

The Figure of the graph is attached below.

We have the Coordinates as (1, 1) and (3, 9).

So, the slope of line

= (9- 1)/ (3-1)

= 8/ 2

= 4

Thus, the slope of line is 4.
