Answer:

x= -4

Step-by-step explanation:

so you add 2 to both sides because on one side it's -2, and remember you need to get x by itself, then you solve for x and get the answer which is -4, here are the steps:

x- 2 = -6

x-2+2= -6 + 2

x - 0 = -4

x = -4

Plot the zeros of this function:<br><br> f(x) = (x – 1)(x – 7).

vredina [299]

Answer:

$\boxed{\mathrm{view \: attachment}}$

Step-by-step explanation:

The zeros of a function is where the function crosses the x-axis. The x-intercepts are the zeros of a function.

$f(x) = (x - 1)(x - 7)$

Let output equal to 0.

$0 = (x - 1)(x - 7)$

Set factors equal to 0.

$x-1=0\\x=1$

$x-7=0\\x=7$

The zeros of the function are $x=1$ and $x=7$ .

Michael: (a)(b)(c)

irinina [24]

Answer:

Ladonna: a + c + b

Step-by-step explanation:

-The commutative property in addition states that the order of arrangement of the integers to be added has no effect on their sum such that:

$x+y=y+x$

-Since the alphabet follows the order a,b, c....

Only Ladonna rearranged to change this order to show the commutative property.

-Hence, Ladonna wrote the expression correctly.

*The commutative property should not be confused with the associative property.

-The latter allows you to change the order and terms within the closed parentheses while retaining the answer.

Help me divide this radical

melisa1 [442]

The 4's will cancel out, then we have to get rid of the sqrt(16) on the bottom

sqrt(15) / sqrt(16)

sqrt(16) = 4

final answer = sqrt(15) / 4.

the answer is C

the original plan for mr Harris's house is a rectangle that measures 40ft by 50ft. because of the increase and cost of materials

Sloan [31]

Answer: The dimesions will be decreased by 13.05%.

Step-by-step explanation:

Hi, we have to calculate the original area.

Area of a rectangle = Length x width

Replacing with the values given:

A = 40x50 = 2000 ft2

Since is reduced to 1739. if we multiply the original area by a the percentage decrease, and subtract that value to the original area, we obtain 1739 ft2.

2000 - (2000x) = 1739

Solving for x

-2000x = 1739 -2000

-2000x = -261

x =-261/-2000

x = 0.1305

Multiply by 1000 to obtain the percentage:

0.1305 x 100 = 13.05%
