Answer:
Step-by-step explanation:
(x²+4)²-11(x²+4)+24=0
put x²+4=y
y²-11y+24=0
y²-3y-8y+24=0
y(y-3)-8(y-3)=0
(y-3)(y-8)=0
y=3,8
so x²+4=3
x²=-1=i²
x=±i
or x²+4=8
x²=4
x=±2
Domain - [-3,3] - What x values there are
Range- [-3,1] - What y values there are
Answer:
<h2>The percentage of the people invited attended the fundraising event is <u>6</u><u>9</u><u>.</u><u>3</u><u>3</u><u>%</u>.</h2>
Step-by-step explanation:
To find the percentage of those who attended the fundraising event, simply divide the number of attendees to the total number invited.
![\frac{416}{640} = 0.69333333 = \boxed{69.33\%}](https://tex.z-dn.net/?f=%20%5Cfrac%7B416%7D%7B640%7D%20%20%3D%200.69333333%20%3D%20%5Cboxed%7B69.33%5C%25%7D)
Answer:
t > 82
Step-by-step explanation:
Given that,
The dance committee of Pine Bluff Middle School earns $72 from a bake sale and will earn $4 for each ticket they sell to the Spring Fling dance.
The dance will cost $400.
We need to find an inequality to determine the number, t, of tickets the committee could sell to have money left over after they pay for this year's dance.
The committee earns $4 for each ticket. It means they will earn $4t.
$72 is constant as they earn it from bake sale.
The total earning must be greayer than $400.
ATQ,
4t + 72 > 400
We can solve the above inequality to find the value of t.
4t > 328
t > 82
Hence, the committee could sell more than 82 tickets to have money left over after they pay for this year's dance.
