The greatest common factor of 60, 24, and 84 is 12
Answer:
equation is y= 50 + 3f
57F
15 Minutes
Step-by-step explanation:
a) the equation above because 50 is the starting temp and every 3 minutes is another degree F
b) if the temp rises 1 degree every 3 minutes, then 21/3 is 7 degrees hotter plus 50, which is 57 F.
c) if 50 plus 3f is the equation, then 3 times 5 will make 55 degrees. After 15 minutes, the temp will be 55 F.
Answer:
d) x-intercept
Step-by-step explanation:
The zeros of a function are the values of x that make y = 0.
Thus, they are the points where the graph crosses the x-axis, that is, the x-intercepts.
a) is wrong. the y-intercept is simply the value of y when x = 0.
b) and c) are wrong. A quadratic can have only one maximum or one minimum; it can't have both. And they are not zeros except in the special case of y = ±ax².
The diagram below is the graph of y = x² + 3x - 46. It shows the zeros at x = -23 and x = 20. The minimum and the y-intercept are not zeros of the function.
Answer:
Let 5 consecutive no's be x,x+1,x+2,x+3,x+4
90 = x+ x+1+x+2+ x+3+x+4
90 = 5x+10
18 = x+2
x= 16
so smallest is 16
greatest = 16+4 = 20
sum = 16 +20 = 36
