Step-by-step explanation:
<u>Given equation</u>
2^x = -2x + 4
To solve graphically, following steps required
1.<u> Graph the function</u>
2. <u>Graph the function</u>
3. <u>Identify any intersection of the lines</u>
4. <u>Take the x-coordinates of the intersection points and record as solution</u>
<em>See attached, the answer and the solution of the given equation</em>
<u>The solution is </u>
Answer: ![(-9, 16]](https://tex.z-dn.net/?f=%28-9%2C%2016%5D)
This is the interval from -9 to 16. Exclude -9 but include 16.
=====================================================
Work Shown:
The idea is to multiply all sides by 5, then add 1 to all sides
This converts to the interval notation
note: a curved parenthesis means "do not include this value in the solution set"; while a square bracket has us include the value. So we exclude -9 and include 16.
It is not because a right triangle needs one right angle, and a right angle is 90 degrees
Step-by-step explanation:
Represent as
w=wally
a=ashan
so wally has 2 more marbles than ashan
w=2+a
together they have 88
w+a=88
since w=2+a, subsitute (2+a) for w in the w+a=88 equation
2+a+a=88
add like terms
2+2a=88
subtract 2 from both sides
2a=86
divide by 2
a=43
ashan has 43 marbles
