Answer:y = 1.5x + 2.5
Step-by-step explanation:
1 radios: 24, 22, 20, 18, 16, 14, 12
2. hours independent, radios dependent
3. (0, 24); (2, 22); (4, 20); (6, 18); (8, 16); (10, 14); (12, 12)
4. 2 radios sold 2 hours
5. goes down by 2
6. n = -h + 24
7. the amount is decreasing every hpur
We know that
in the triangle ACB
∠ACB+90+34=180-----> ∠ACB=180-(90+34)----> ∠ACB=56°
∠ACD and ∠ACB-----> are supplementary angles
so
∠ACD+∠ACB=180-----> ∠ACD=180-56----> 124°------> x=124°
the answer Part 1) is x=124°
Part 2)
∠ACB+∠BCF+80=180-----> ∠BCF=180-(∠ACB+80)---> 180-(56+80)
∠BCF=180-136----> 44°-----> y=44°
the answer Part 2) is y=44°
Answer:
6 numbers satisy the inequality:
x = -1, 0, 1, 2, 3, 4
Step-by-step explanation:
x is greater than -2 and 5 is greater than x.
-2 < -1 < 5
-2 < 0 < 5
-2 < 1 < 5
-2 < 2 < 5
-2 < 3 < 5
-2 < 4 < 5
Answer:
1.5
Step-by-step explanation:
the slope is regarded as :
= ![\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
this is also known as the <em>gradient </em>, meaning the differences of two y values divided by the differences of the two corresponding x values
take two values on the slope and put in the form ( x,y)
we shall use two points A and B
A = (80 , 100)
B = (20 , 10)
now use the formula:
![\frac{10-100}{20-80}](https://tex.z-dn.net/?f=%5Cfrac%7B10-100%7D%7B20-80%7D)
=![\frac{-90}{-60}](https://tex.z-dn.net/?f=%5Cfrac%7B-90%7D%7B-60%7D)
= ![\frac{3}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B2%7D)
also can be represented into an integer form
answer is <u>1.5</u>
