Answer:
HCF of 120 and 180 is 60 and hence a measuring tin of 60 litre volume should be bought.
Answer:
An equation of the line with the given information with
m = 4 and point A(-1, -5) is:
Step-by-step explanation:
As the equation of a line in point-slope form is given by:
where m is the slope.
Given:
Substituting the values in the equation of a line in point-slope form
subtract 5 from both the sides
Therefore, an equation of the line with the given information
with m = 4 and point A(-1, -5) is:
Answer:
i think . it is c
Step-by-step explanation:
First, we have to realize that this is factored form, so we have to put this in standard quadratic form using FOIL, which is a rule mandating how we multiply the numbers here. F stands for First, which means the first number inside the parentheses for both of them, then O means the first number in the first quantity(fancy word for parentheses) multiplied by the last number of the second quantity, and so forth. When you are done, you combine like terms
anyway, you end up with x²-12x-189, but you have to inverse all numbers because of the parentheses in front, so it becomes -x²+12x+189.
Now you can find the axis of symmetry uisng the equation -b=2a (oh yeah, I forgot to mention: the standard quadratic form is a(x)²+b(x)+c already). So you do -12 / -2, which then becomes 6.
The axis of symmetry is 6
