y = abˣ
20 = ab¹
20 = ab
b b
20/b = a
y = abˣ
4 = (20/b)b²
4 = 20b
20 20
¹/₅ = b
y = abˣ
20 = ¹/₅b¹
20 = ¹/₅b
¹/₅ ¹/₅
100 = b
y = abˣ
y = 100(0.2)ˣ
How can I send you the drawn representation on number line ?
25)
z + 4 >= 2z
-z >= -4
z <= 4 (you flip the sign when you divide over negative number)
on number line: from 4 to -infinity
you use normal arithmetic like equations
29)
-9 + 2a < 3a
-9 < a (just one step done)
on number line from -9 to infinity
41 and 43 ? not in the page
Answer:
2
Step-by-step explanation:
<u>Let's see what information we get from this picture</u>:
<u>First information</u>
⇒ <em>triangle is an isosceles triangle</em>
⇒ meaning that the 'unlabeled angle' adjacent to 'angle of measure x'
⇒ are equal
<u>Second information:</u>
⇒sum of all the angle's measure of a triangle is 180 degrees
⇒ 
<u>Let's solve</u>:

<u>Answer: 55</u>
Hope that helps!
