Answer:
(y-(-3))=4(x-(-1))
Step-by-step explanation:
formula for point slope form is:
y-y1=m(x-x1)
just plug in numbers from the point (-1, -3) for x1 and y1. The slope 4, would plug into m.
Answer:
9 cookies per dollar
Step-by-step explanation:
This is a fraction equal to
36 cookies ÷ 4 dollars
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 4
36 cookies ÷ 4
--------------------------
4 dollars ÷ 4
=
9 cookies
---------------
1 dollar
=
9 cookies
-----------------
dollar
= 9 cookies per dollar
Answer: i believe it would be (-3 , 5)
Step-by-step explanation:
Correct me if im wrong
The unit rate is 2/3 because in the line y=2/3x, 2/3 is the slope (y=mx+b). The slope of the line is pretty much the definition of a unit rate because the unit rate is a constant addition or subtraction over and over. In addition, it is a straight line(y=mx+b) and the values are going up at a constant rate of 2/3.
Answer:
d and e
Step-by-step explanation:
To factor 4x² + 17x - 15
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term, that is
product = 4 × - 15 = - 60 and sum = + 17
The factors are + 20 and - 3
Use these factors to split the middle term
4x² + 20x - 3x - 15 ( factor by grouping the first/second and third/fourth terms )
= 4x(x + 5) - 3(x + 5) ( take out the common factor (x + 5) )
= (x + 5)(4x - 3) → d/e
