Your first step is C. Find a common denominator
Answer:
C
Step-by-step explanation:
y》0.5x + 1.8
x = 4, y = 4.5
4.5》0.5(4) + 1.8
4.5》3.8 (true)
Answer:
The slope is -1/3
Step-by-step explanation:
We can find the slope of a line using the formula
m = (y2-y1)/(x2-x1)
= (2-3)/(3-0)
= (-1/3)
=-1/3
Answer:
<em>D = 41</em>
Step-by-step explanation:
y = ax² + bx + c
The discriminant D = b² - 4ac tells the types of roots the equation has.
If D < 0 , then quadratic equation has no real roots, has two imaginary roots.
If D = 0 , then quadratic equation has one real root.
If D > 0 , then quadratic equation has two distinct real roots.
~~~~~~~~~~~~
x² + 5x - 4
a = 1, b = 5, c = - 4
<em>D </em>= 5² - 4(1)(- 4) = 25 + 16 =<em> 41</em>
Answer:
80, 70 and 87
Step-by-step explanation:
-Range is mathematically defined as the difference between the largest and smallest data point in a data set.
-Given the mean=79, median=80 and the range is 17.
#let a be the largest score and b be the smallest score:
The sum of the 3 scores is equivalent to the 237.
#we subtract the given median and equate using range to solve for a and b;
Hence, the test scores are 80, 70 and 87
