X^4=256
x^4-256=0
(x^2)^2-(16)^2=0
(x^2+16)(x^2-16)=0
either x^2+16=0
it gives complex roots.
or x^2-16=0
or x^2-4^2=0
(x+4)(x-4)=0
either x+4=0,x=-4
or x-4=0
x=4
Answer:
option 2nd
Step-by-step explanation:
You've selected wrong one
it's first row, last one
to find the graph is a function or not, it should pass vertical line test.
Draw a vertical line through each graph. It should not cut your graph more than once.
2nd graph from first row is passing vertical line test. so it is a function b
9x+15=8x
subtract 15 and 8x from both sides to get
x=-15
Okay. So 25 cents is expressed as 0.25. it is $0.25 for a square foot of grass seed. To find the cost for 55,000 square feet of grass seed, all you have to do is multiply the cost per square foot by the amount of square feet total. In this case, we would multiply 55,000 by 0.25. 55,000 * 0.25 is 13,750. There. The total cost would be $13,750.
