Answer:
Step-by-step explanation:
Use the slope-intercept form
y=mx+b
to find the slope m and y-intercept b.
Slope: −13
y-intercept: (0,−9)
A = 1/2[(7)(19) + (12)(19)]
A = 1/2[133 + 228]
A = 361/2
A = 180.5
answer
D. 180.5 square inches
Answer:
No
Step-by-step explanation:
Apply the distributive property to 5(2x - 3y):
Multiply 5 by each term inside the parentheses.
5(2x - 3y) = 10x - 15y
The other expression is 10x - 10y.
The terms 10x in both expressions are equal.
Since the term -15y is not equal to the term -10y, the expressions are not equivalent.
Answer:
1/2
Step-by-step explanation:
Let's pick two points and find the slope inbetween them.
I'll pick (2,1) and (0,0).
Remember that slope = change in y / change in x.
slope = 1-0 / 2-0 = 1/2
Answer: The required number of boys in the class is 18.
Step-by-step explanation: Given that in math class, the girl to boy ratio is 8 to 6 and there are 24 girls in the class.
We are to find the number of boys in the class.
Let 8x and 6x represents the number of girls and boys in the class.
Then, according to the given information, we have
Therefore, the number of boys in the class is given by
Thus, the required number of boys in the class is 18.
