1) 52 + 33= 85
2) 26 + 42 = 68 or 26 - 42 = - 16
3) 72 - 2015 = =1943
4) 32 x 22 = 704
Answer:
y = -2sin(x) + 2
Step-by-step explanation:
The sin(x) function is zero at x=0, so you want a sine function of some sort. The slope of your graph at x=0 is negative so you want a sine function with a negative multiplier. The appropriate choice is the one shown above.
__
The cos(x) function is 1 at x=0, so any graph involving the cosine will not go through the point (0, 2) the way your graph does.
Answer:
She lives 1/5 miles away from the library
Step-by-step explanation:
Here, we want to get the distance that Sheila
lives from the library
From the question, we are told she lives 1/3 as far as Doreen
So what we have to do in this case is to simply multiply the distances
we have this as:
1/3 * 3/5 = 1/5
26 + 35 + 37 + 46 = 144
Every 3 feet is one yard, so 144/3 = 48
48 Yards
Answer:
Mom === 10.25
Daughter === 3.25
Step-by-step explanation:
Let’s the mom age be 7+x and the daughters age be x. Put it in a linear equation 7+x=5(4+x).
open the bracket which will give you 7+x=20+5x.
collect like terms which will give you 5x-x=20–7 and you will get 4x=13 where x is 3.25 the mom is 10.25 and the daughters age is 3.25
