y=mx+b is the standard function for any straight line
y and x are constants, so they never change in the final form
m is the slope, which is given
b is the y intercept, which is not given
we have to plug in the values to find the solution, so plug in the (x,y) coordinates for their respective places in the equation
-8 = (-3/5)(-3) + b
-8 = 1.8 + b
-9.8 = b
now that we have b, we can just put the slope back in for m and get the answer
y= -3/5x -9.8
Answer:
So, the coefficient of the x^2 -term is 80
Step-by-step explanation:
so we need to simplify it:
#10(x^2)(2^3) = 10(x^2)(8) = 80x^2
Answer:
You could show them by using different set of blocks for different placements.
such as a cetain type of block for the ones place, a different kind for the tens place.
You can color code it so that they could distinguish the different numbers.
Answer:
)x + 5)(x - 5)
Step-by-step explanation:
x² - 25 ← is a difference of squares and factors in general as
a² - b² = (a + b)(a - b), thus
x² - 25 = x² - 5² = (x + 5)(x - 5)
