3x-91>-87 AND 17x-16>18

Mathematics

Answer:

( 2, ∞ )

Step-by-step explanation:

Given compound inequality,

3x-91 > -87 and 17x-16 > 18,

3x > -87 + 91 and 17x > 18 + 16

3x > 4 and 17x > 34

x > \frac{4}{3} and x > 2

Since, if x > \frac{4}{3}

x ∈ ( \frac{4}{3}, ∞ )

If x > 2

x ∈ ( 2, ∞ )

Now, x > \frac{4}{3} and x > 2

\implies (\frac{4}{3}, \infty)\cap (2, \infty)

= ( 2, ∞ )

Hence, the possible solution of the given compound inequality is (2, ∞)

Which side lengths form a right triangle? Choose all answers that apply: Choose all answers that apply: (Choice A) A 3, 6, \sqrt
dlinn [17]

Answer:

A, B and C

Step-by-step explanation:

Given any three side lengths of a right triangle, the longest side is the hypotenuse.

The side lengths  of a right triangle must satisfy the <u>Pythagorean Theorem. </u>

Pythagorean Theorem: Hypotenuse^2=Opposite^2+Adjacent^2

<u>Option A:</u> 3, 6, \sqrt{45}

(\sqrt{45})^2=3^2+6^2\\45=36+9\\45=45

True

<u>Option B:</u> 2.5, 6, 6.5

6.5^2=6^2+2.5^2\\42.25=36+6.25\\42.25=42.25 (TRUE)

<u>Option C:</u> 4, 8, \sqrt{80}

4, 8, \sqrt{80}\\( \sqrt{80})^2=4^2+8^2\\80=16+64\\80=80 (TRUE)

Since all are true, the side lengths in Options A, B and C forms a right triangle,

Someone please help :(

Answer:

y = -0.2x + 8

Step-by-step explanation:

To write a linear function, calculate the rate of change of the gallon of water leaving the tank and the starting level.

The function will describe the number of gallons over time or (time, gallons).

This means the function has data points (1, 7.8) and (9, 6.2).

Use the rate of change or slope formula to calculate it.

m = \frac{7.8 - 6.2}{1 - 9} =\frac{1.6}{-8} = -0.2

This means that for the formula y = mx+b then m = -0.2.

This also means that after losing 0.2 gallons the first hour it was at 7.8. So the starting value is 8 gallons.

The equation is y = -0.2 x + 8.
