If f(x )= 2x - 3 find the value of f(3) + f(0)
Nana76 [90]

Answer:

0

Step-by-step explanation:

Let's find f(3) first

All we need to do is plug 3 in the place of x

2(3) - 3

6 - 3 = 3

Now let's find f(0)

Do the same thing for the first one, plug the new number in the place of x

2(0) - 3 = -3

A department store sells yellow and purple shirts. Each yellow shirt is the same price. Each purple shirt is the same price. How
Aleksandr [31]

Answer:

The Cost of  yellow shirts is $15 and the cost of purple shirt is $ 60

Step-by-step explanation:

Let cost of one yellow shirt be x

and the cost of one purple shirt be y

On Monday

5x + 7y = 165--------------------(1)

On Tuesday

4x + 11y = 213----------------------(2)

To solve (1) and (2)

multiplying eq(1) with 4

20x + 28y = 660--------------------(3)

multiplying eq(2) with 5

20x + 55y = 1056-------------------(4)

Subtracting (3) from (4)

20x + 55y = 1056

20x + 28y = 660

(-)

-----------------------------------

0x  +27y = 405

-----------------------------------

y = \frac{405}{27}

y = 15

Substituting y value in eq(1)

5x + 7(15) = 165

5x + 105 =405

5x =405 -105

5x =300

x = \frac{300}{5}

x =60

Ubehebe crater in Death Valley has a diameter of a little more than 1/2 mile. If latisha walks around it's rim at a rate of 2 mi
Yuri [45]
Let's say that the diameter was 1/2 mile. So the diameter is 1/2,  then you need to find the circumference, aka perimeter of the circle. So 1/2 times 3.14 = 1.57 miles So then you would do 1.57/2 = .785 of an hour If you round to nearest tenth The answer is .8 of an hour.
