H(x) = 17 + x/6 h(-18) = ___ x/6 is a fraction please helpp

1 answer:

6 0

Simply plug in the value for x.

If x is equal to -18, then plug in -18 for x.

Example:

f(x) = 15 + x/5.
f(5) = 15 + 5/5.

Then solve the equation.

A function is just something that receives some value and then barfs a value out. This is an IO relationship. (Input/Output).

The width of a rectangle is 5 centimeters less than the length . The area of the rectangle is 36 centimeters.find the length?

Iteru [2.4K]

Answer:

9 centimeters

Step-by-step explanation:

Let the width be represented by l - 5, where l is the length.

Use the area formula, A = lw, and plug in l - 5 as w, and 36 as the area. Then, simplify and factor

A = lw

36 = l(l - 5)

36 = l² - 5l

0 = l² - 5l - 36

Factor:

(l - 9)(l + 4)

Set equal to zero and solve for both solutions:

(l - 9)(l + 4) = 0

l - 9 = 0

l = 9

l + 4 = 0

l = -4

The length cannot be negative, so the answer has to be 9.

The length is 9 centimeters

A total of $2100 for a house painting job is to be divided between two painters in the ratio of 3 to 4. How much does each paint

kakasveta [241]

$\bf 2100\qquad 3:4\qquad \cfrac{3}{4}\implies \cfrac{3\cdot \frac{2100}{3+4}}{4\cdot \frac{2100}{3+4}}\implies \cfrac{3\cdot 300}{4\cdot 300}\implies \cfrac{900}{1200}$

The vertices of a triangle are A(0, 0), B(3, 8), and C(9, 0). What is the area of this triangle?

Harlamova29_29 [7]

Answer: 36 units squared.

Explanation:
Area of a traingle is given by,

| 0.5{x1(y2-y3) + x2(y3-y1) + x3(y1-y2)} |

Accepting the values of the coordinates in x's and y's,

x1 =0, y1=0

x2=3, y2=8

x3 =9, y3=0

= | 0.5 × (-72)|
= 36 unit squared.
