(5+2)^2 -40 +3 =

PEMDAS

Parentheses first

(7)^2 -40 +3 =

Exponents

Answer:

see explanation

Step-by-step explanation:

Given the zero x = a of f(x) then f(a) = 0

(5)

f(9) =9³ - 8(9)² - 2(9) - 63 = 729 - 648 - 18 - 63 = 0

Hence x = 9 is a zero of the polynomial

(6)

2 $(-3)^{4}$ - 3(- 3)³ - 36(- 3)² - 37(- 3) - 26 = 162 + 81 - 324 + 111 - 26 = 4 ≠ 0

Hence x = - 3 is not a zero of the polynomial

You have the set (0,5) (2,7) (3,11) (7,4) (10,5). If you added (2,1) to the set, why would it no longer be a function?

brilliants [131]

Answer:

No, it would no longer be function.

Step-by-step explanation:

Because then there would be two different y values for the x value 2.

Answer:

18 and 20, 4

Step-by-step explanation:

Math reasoning 1:

Set the first number as x and the other one as x+2 because it is a consecutive even number.

x+x+2=38

2x=36

x=18

18+2=20

The 2 consecutive numbers are 18 and 20

Problem solving 1:

Write out equation first, set the unknown number as x

5+x=9

x=4

Write an equation in slope intercept form that passes through -2, 3 and Is parallel to the line with equation 3X +2y=6

soldier1979 [14.2K]

The equation of line is: $y=-\frac{3}{2}x$ as the y-intercept is zero

Step-by-step explanation:

Given

(-2,3)

Equation of line => 3x+2y=6

Converting the equation in slope intercept form

$3x+2y=6\\2y=-3x+6\\Dividing\ both\ sides\ by\ 2\\\frac{2y}{2}=-\frac{3}{2}x+\frac{6}{2}\\y=-\frac{3}{2}x+3$

The co-efiicient of x is the slope of the fiven line

So,

m=-3/2

The line parallel to given line will have the same slope as slopes of two parallel lines are equal

Now,

Slope-intercept form is:

$y=mx+b$

Putting the value of slope

$y=-\frac{3}{2}x+b$

to find the value of b, put (-2,3) in the equation

$3=-\frac{3}{2}(-2)+b\\3=3+b\\b=0\\$

Putting the value of b and m

$y=-\frac{3}{2}x+0\\y=-\frac{3}{2}x$

Hence,

The equation of line is: $y=-\frac{3}{2}x$ as the y-intercept is zero
