This is false, since moving the decimal point to the left makes the number smaller. Therefore, the number on the exponent should be negative.
Answer:
9a^2sqrt(ab)
Step-by-step explanation:
The first noticable thing is that 81 has a perfect square of 9.
So it is now 9sqrt(a^5b)
you can split the a^5, to a^4 × a.
you can now take the sqrt of a^4, which is a^2, and pull it out from the sqrt
You are now left with 9a^2sqrt(ab)
To solve this equation, we have to use the distributive property to multiply 5y through the parentheses.
-45y - 15y^2 = 13
-15y^2 - 45y - 13 = 0
15y^2-45y-13=0
<span>y=<span><span>32</span>+<span><span><span><span>130</span><span>√2805</span></span><span> or </span></span>y</span></span></span>=<span><span>32</span><span><span><span>−1</span>30</span><span>√<span>2805, when you use the quadratic formula.</span></span></span></span>
You have the equation, now you need two points to graph, using the intercept method, "(0,?), (?,0)"
When x is 0 (substitute x with 0 in the equation, to find y)...y = 40
When y is 0 (substitute y with 0 in the equation, to find x)...x = 0.67
You have your 2 points (0,40) and (0.67,0), now graph them and draw a line connecting the 2 points..and u have your graph!
