Answer:

Step-by-step explanation:

X-intercepts mean y=0 so we have

y = x³ - 9x² + 18x = 0

Factoring

x³ - 9x² + 18x = 0

x*(x² - 9x +18) = 0

x*(x-3)*(x-6) = 0

So x-intercepts are at x=0, x=3 and x=6

5 (- 3 x - 2) - (x - 3) = - 4 (4 x + 5) + 13
Montano1993 [528]
PEMDAS
parentheses, exponent, multiplication/division, addition/subtraction
first, start with what is inside the parentheses that is solvable.
5(6) - (x-3) = -4(4x+5) + 13
multiply what you can
30 - (x-3) = -16x - 20 + 13
simplify
30 - (x-3) = -16x - 7
subtract 30 on both sides
- (x-3) = -16x - 37
let’s separate -(x-3).
-x - 3 = -16x - 37
add 16x to both sides
15x - 3 = -37
add 3 to both sides
15x = -34
x = -34/15 or -2.2667

Use the distributive property to rewrite each expression. I need help with number 7.
ExtremeBDS [4]
The distributive property is when the coefficient in front of the parentheses is applied to both terms inside.
a. distribute the 6 to make 6xa+6x5. simplify to make 6a+30
b. distribute the 12 to make 12x4+12x3a. simplify to make 48+36a
c. distribute the c to make (1/2)xb-(1/2)x12. simplify to make (b/2)-6

The table shows a linear function.
FinnZ [79.3K]

Answer:

B) f(x) = -3/5x +5

Step-by-step explanation:

There are several ways you can write the equation of a line from a list of points. When you look through the list and see that one of them is the y-intercept, then the problem can be easier. When you look through the list of answers and see that the required answer is in slope-intercept form, then you know all you need to do is find the slope to go with the intercept you've located.

The point (x, f(x)) = (0, 5) tells you the y-intercept is 5.

The slope, the change in y divided by the change in x for two points, is ...

... (-1 -2)/(10 -5) = -3/5

This is the slope and the coefficient of x in the linear equation.

Now, we know the y-intercept (b=5) and the slope (m=-3/5), so we can fill in the slope-intercept form of the equation of a line:

... y = mx + b

... y = (-3/5)x + 5
