Answer:

y = - $\frac{1}{3}$ x + 1

Step-by-step explanation:

The equation of a line is: y = mx + c where m is the slope of the line and c is the y-intercept. I will be calculating the slope using the points (3, 0) and (0, 1).

Slope = $\frac{0-1}{3-0}$

= $\frac{-1}{3}$

Thus, the slope of the line is - $\frac{1}{3}$ .

Based on the graph, the y-intercept is 1.

Thus, the equation of the line is: y = - $\frac{1}{3}$ x + 1.

How do you find the base area of a rectangular prism and a cylinder? Please help

Pani-rosa [81]

Answer:

See explanation.

Step-by-step explanation:

The 'base' of a rectangular prism refers to only one side of the rectangular prism, which is a rectangle.

The formula for the area of a rectangle is as follows:

$A=lw$

Where A = area, l = length, and w = width.

The 'base' of a cylinder refers to only one side of the cylinder, which is a circle.

The formula for the area of a circle is as follows:

$A=\pi r^2$

Where A = area and r = radius.

Just in case you typed your question incorrectly and were asking for surface area, here is the formula for surface area for both as well:

Rectangular prism: $A=2(wl+hl+hw)\\$

Cylinder: $A=2\pi rh+2\pi r^{2}$

Alex, Bob and Carl go for a walk every day. If Alex doesn't wear a hat, then Bob wears

bazaltina [42]

Answer:

Carl and Alex are wearing hats.

Step-by-step explanation:

If Bob doesn't isn't wearing a hat, then Carl is, so Carl clearly is wearing a hat.

Now let's look at Alex. If he wasn't wearing a hat, then Bob would be wearing one. (If Alex doesn't wear a hat, then Bob wears

a hat). The logical conclusion is that Alex must be wearing a hat as well.

What is the value of a in the equation 5a – 10b = 45, when b = 3?

LenKa [72]

5a - 10*3 = 45
5a - 30 = 45
5a = 45 + 30
5a = 75
a = 15

kogti [31]

Answer:

67.5

Step-by-step explanation:

I've learned this multiple ways but in my opinion this is the easiest. Just times everything together so, 40 x 2.5 x 1.2 which equals 135 and then divide 135 by 2 which equals your answer of 67.5 which is rounded to the nearestt tenth already.
