So hmm check the picture below

the height or altitude is CD
and the base is AB

how long are those? well \bf \textit{distance between 2 points}\\ \quad \\
\begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%  (a,b)
A&({{ 6}}\quad ,&{{ 0}})\quad 
%  (c,d)
B&({{ 1}}\quad ,&{{ 5}})\\\\
C&({{ 2}}\quad ,&{{ 0}})\quad 
%  (c,d)
D&({{ 4}}\quad ,&{{ 2}})
\end{array}\qquad 
%  distance value
d = \sqrt{({{ x_2}}-{{ x_1}})^2 + ({{ y_2}}-{{ y_1}})^2}
\\\\\\
AB=\sqrt{(1-6)^2+(5-0)^2}\qquad \qquad CD=\sqrt{(4-2)^2+(2-0)^2}

Which ordered pairs make both inequalities true? Check all that apply.
Thepotemich [5.8K]
All others did not satisfy the inequality simultaneously except #4 and #6
For #4:
2 < 5(1) + 2 i.e. 2 < 7 (true)
2 >= 1/2(1) + 1 i.e. 2 >= 3/2  (true)
For #6
2 < 5(2) + 2 i.e. 2 < 12 (true)
2 >= 1/2(2) + 1 i.e. 2 >= 2

Which tables represent constant functions?
Alona [7]

A function is a law that tells you how to associate inputs (x values) and outputs (y values).

In the case of constant functions, it doesn't matter which input you choose, the ouput must always be the same.

So, a constant function has always the same output (y values) for every input (x values) you feed.

Divide £250 in the ratio 3:6:1
Nina [5.8K]

Answer:

Step-by-step explanation:

The numbers in the ratio add up to 10. So divide 250 by 10. One part is £25. Multiply by the given numbers: 3x25=75. 6x25=150. 1x25=25. So you have £75:£150:£25.

Bonnie ran 1/4 mile, Olga ran 3/4 mile, Gracie ran
Ainat [17]

Answer:

2/4

Step-by-step explanation:

Bonnie and  Maria combined = 1/4 + 2/4 = 3/4

Gracie run = 5/4

=> How much  farther, f, did Gracie run than Bonnie and  Maria combined

= 5/4 - 3/4 = 2/4

So Gracie run 2/4 more than Bonnie and  Maria combined

you have a bottle with a leak . after 2 seconds there are 28 ounces left in the bottle. after 6 seconds , there are 20 ounces le
Arte-miy333 [17]
We determine first the rate of flow of water out of the bottle by dividing the difference in the volume with the difference in time. 
                           r = (28 - 20) / (6 - 2)
                             r = 2 ounce/s
We calculate the first term by adding 2 ounce/s to the 2nd term, giving us the answer which is equal to 30 ounce/second.
