All of the statements has the qualifier "can be".
This means that we need just one single in each example to make the statement true.
In an equilateral triangle, medians, angle bisectors, altitudes and perpendicular bisectors are all coincident, which makes the first three statements true. This in turn makes the fourth statement true.
So there are no false statements.
Answer:
The equation of this line would be y = 3x - 1
Step-by-step explanation:
In order to find this equation we must first find the slope of the original line. The original slope (the coefficient of x) is 3, which means the new slope will also be 3 because parallel lines have the same slope. Now, we can use this slope along with the point in point-slope form to find the equation of the line.
y - y1 = m(x - x1)
y + 7 = 3(x + 2)
y + 7 = 3x + 6
y = 3x - 1
Answer:
The function graphed is f(x) = 3x + 1
See that the y=intercept is at (0,1). That's where the +1 comes from.
Note that the graph goes up 3 spaces every time it goes 1 to the right. 3/1 = 3 is the slope.
The answer to 12 is C.
The answer to 13 is B. Neither is a function. For a function of x to exist, for every x, there must be only one y. In both tables, there's a number for x that gives two different y's.
Step-by-step explanation:
Answer:
7(2+9)
It says the sum of 2 and 9 so I added them both together. It says product so I multiplied 7 to the sum of 2 and 9.
Answer:
c =3.9375 hours
Step-by-step explanation:
The formula to determine time to finish the job together is
1/a + 1/b = 1/c
Where a and b are the times to complete the job separately and c is the time to complete the job when working together
1/7 + 1/9 = 1/c
Multiply by 63c to get rid of the fractions
63c*(1/7 + 1/9) = 1/c *63c
9c + 7c = 63
Combine like terms
16c = 63
Divide each side by 16
16c/16 = 63/16
c =3.9375 hours
