Answer: -2-8= -10

4+1 = 5 (the negative switches to a positive)

Your slope equals -10/5. You can look at this in a fraction for when you might use it later in point slope or slope intercept form, or you can just simplify it to -2. It might also be helpful to remember the numerator as the rise and the denominator as run, or “rise over run” if you need to graph it.

Slope = -10/5 or -2

Step-by-step explanation:

Slope, often referred to as the variable “m” can be found by solving y2-y1/x2-x1. You can do it the opposite way, though make sure the y-values are on the top.

Answer:

-5/6

Step-by-step explanation:

-1-4=-5

8-(-2)=-6

the slope is m=-5/6

m=rise/run=y₂-y₁/x₂-x₁

An angelfish was 1 1/2 inches long when it was bought. Now it is 2 1/3 inches long.
____ [38]

A)

Earlier, The length of the angelfish  = 1 \frac{1}{2} inches

Now, the length of angelfish = 2 \frac{1}{3} inches

We have to determine the grown length of angelfish

=  2 \frac{1}{3} -  1 \frac{1}{2}

= \frac{7}{3}- \frac{3}{2}

LCM of '2' and '3' is '6',

= \frac{14-9}{6}

= \frac{5}{6} inch

Therefore, the angelfish has grown by \frac{5}{6} inch.

B)

We have to determine the increased length of angelfish in feet.

Since 1 inch = \frac{1}{12} foot

So, \frac{5}{6} inch = \frac{5}{6} \times \frac{1}{12} = \frac{5}{72}

= 0.069 foot.

Please help! I need the surface area for both. Absurd answer are not tolerated. Thanks if you help!
Natasha_Volkova [10]

Answer:

<h3>Figure 1</h3>
  • Perimeter of base = 5 + 5 + 8 = 18 ft
  • Height = 7 ft
  • Base area = 1/2(8)(3) = 12 ft²

<u>Surface area:</u>

  • S = 18*7 + 2*12 = 150 ft²
<h3>Figure 2</h3>

<u>Surface area of cube:</u>

  • S = 6a² = 6(2.5)² = 37.5 m²

<u>Surface area of prism:</u>

  • S = 2(11 + 9)(7) = 280 m²

<u>Overlapping area:</u>

  • S = 2.5² = 6.25 m²

<u>Surface area of composite figure:</u>

  • S = 280 + 37.5 - 2(6.25) = 305 m²
