(5y - 3)(2y + 5) = 10y² + 25y - 6y - 15
= 10y² + 19y - 15

Answer:
32.63 F
Step-by-step explanation:
The function:
represents sound travels s at feet per second, where t is the temperature at Fahrenheit degrees.
We know that sound traveled at a rate of 1121 ft/sec. To find the temperature we need to replace with s value and isolate t for the above function.
Answer:
90
Step-by-step explanation:
2 presents per 4 minutes is 30 presents per hour multiplied by 6 hours is 90 presents
A number line ranges from minus 5 to 5 with increment of 1 unit. Left, Point F is plotted on the number line at minus 3. Right, point G is plotted on the number line at 1.50, then the distance between F and G is 4.50.
Calculating the Distance between F and G:
It is given that, on a number line,
Point F is located at -3
Point G is at 1.50
Since, 1.5 > (-3) and each number is at a 1 unit difference form the adjacent number on the number line,
The difference between F and G = 1.50 - ( -3 )
This implies that the distance between F and G = 1.50 + 3
= 4.50 units
The numbers lying between the points F and G on the number line are: -2, -1, 0, and 1
