Use the distributive property
5*2x + 5*3y
10x + 15y
Answer:
two quadratic functions combined by addition
a linear function and a quadratic function combined by addition
two linear functions combined by multiplication
Step-by-step explanation:
-3x² + 5
(-4x² + 4) + (x² + 1)
-3x² + 5
(-3x² - x) + (x + 5)
-3x² + 5
(sqrt(5) - sqrt(3)x)(sqrt(5) + sqrt(3)x)
Answer:
x=2 1/4
Step-by-step explanation:
Let's swap it around so its 1/3(8x+3)=7
Now you multiply both sides by 3 to make it 1(8x+3)=21
That means its 8x+3= 21
Subtract both sides by 3 to get rid of it
Now you have 8x=18
Which equals to x= 18/8
Which equals 2 1/4
Answer: data set a= 4.5
Data set b= 5
Step-by-step explanation:
data set a: 3+4+4+4+5+5+5+6=36
36÷8= 4.5
Data set b: 3+3+3+4+4+5+5+6+6+7+7+7=60
60÷12=5
