Question #1

Part A:
The y-intercept can be found when x = 0. If you look at your table, when x = 0, y = 5. So the y-intercept is 5.

Part B:
$\sf Slope = \frac{27-5}{1-0} = \frac{22}{1} = \boxed{22}$
The slope is 22.

Part C:
y = mx + b
y = 22x + 5

We are given 225 as the range, or in place of y.
225 = 22x + 5
220 = 22x
x = 10

The domain is 10.

Question #2

Part A:

(2,255)
(5,480)

Standard form is Ax + By = C

$\sf Slope = \frac{y_2-y_1}{x_2-x_1} = \frac{480-225}{5-2} = \frac{255}{3} = \boxed{85}$

Let's plug this into this form first:
$y - y_1 = m(x-x_1)\\\\y -225 = 85(x-2)\\\\y - 225 = 85x - 170\\\\y = 85x + 55$

Now, let's make it into Standard Form.
$y = 85x + 55\\\\y - 85x + 55\\\\ -85x + y = 55\\\\ -1(-85x +y) = -1(55)\\\\\boxed{85x - y = -55}$
What, which is in the box, is your final answer. :)

Part B:
Function notation simply means replacing y with f(x).
We had y = 85x + 55
So your answer is:
$\boxed{f(x) = 85x + 55}$

Part C:
Using the final answer which we got in Part A, we would know that the y-intercept is (0,55) and the x-intercept is (-55/85, 0). We would plot these 2 points, and then draw a line between them. :)

Answer:

Step-by-step explanation:

We know it is not SSS or AAS or ASA

On one triangle we have SAS but we don't see the same congruent markings so we cannot tell.

In a fifth grade class 4/5 of the girls have brown hair. Of the brown-haired girls, 3/4 of them have long hair. Of the girl with

Aleks [24]

lets say there are 100 girls.
4/5 of 100 is 80, so 80 girls have brown hair.
3/4 of the 80 who have brown hair have long hair.
3/4 of 80 is 60.
so we know that out of 100, 60 have long brown hair.
in simplest fraction form, 60/100= 3/5

Answer:

222.7 cm³ of paper to wrap this.

Step-by-step explanation:

The rectangular prism is SA=2(wl+hl+hw)

Where:

w=5 l=5 h=4

SA= 2((5*5)+(4*5)+(4*5))

SA=2(25+20+20)

SA=2(65)=130cm³

The square base pyramid is $A= lw+l\sqrt{x} (w/2)^2+h^2+w +w\sqrt{x} (1/w)^2+h^2$

$SA= 6*5+6*\sqrt{x} (5/2)^2+5^2+5*\sqrt{x} (6/2)^2$

≈92.69578 cm³

Add the two together 130+92.70 =222.7 cm³
