How do I rewrite the linear expression by factoring out the coefficient of the variable

1 answer:

3 0

so your example can work as -1(x+10), factoring out coefficients usually pertains to finding the highest number (and variable) that an equation can be multiplied by, note that a variable can work the same 2x^2(x+2) is the same as 2x^3+4x^2

How do you find the square root of 2809

Hunter-Best [27]

If this is greater than the first part of the number called by the spectator (i.e., ignoring the last two digits), then the last digit of your answer is the lower of the two possible values. Otherwise the last digit is the higher value. For example if the number called is 2809, the square root could be either 53 or 57.

Pavlova-9 [17]

Answer: y is the dependent variable

Step-by-step explanation:

In mathematics, a function is a rule for taking an input and providing an output.

A symbol that stands for an arbitrary input is called an independent variable.

A symbol that stands for an output that depends on the value of a independent variable is called a dependent variable.

y = 12x } Function

x is the independent variable = arbitrary number of hours worked.

y is the dependent variable because depends on the value of x.

(9x+13)^2=49<br> Solve the quadratic equation given below.

Varvara68 [4.7K]

Answer:

x=(-2/3)

Step-by-step explanation:

(9x+13)^2=49

√(9x+13)^2=√49

9x+13=7

9x+13-13=7-13

9x=-6

9x÷9=-6/9

x=-6/9

-6/9=-2/3

Serena has attached a 10 inch ribbon to the corners of a frame to hang it on the wall. The frame 9 inches wide. How far above th

kherson [118]

Answer: The hook would be 2.2 inches (approximately) above the top of the frame

Step-by-step explanation: Please refer to the picture attached for further details.

The top of the picture frame has been given as 9 inches and a 10 inch ribbon has been attached in order to hang it on a wall. The ribbon at the point of being hung up would be divided into 5 inches on either side (as shown in the picture). The line from the tip/hook down to the frame would divide the length of the frame into two equal lengths, that is 4.5 inches on either side of the hook. This would effectively give us two similar right angled triangles with sides 5 inches, 4.5 inches and a third side yet unknown. That third side is the distance from the hook to the top of the frame. The distance is calculated by using the Pythagoras theorem which states as follows;

AC^2 = AB^2 + BC^2

Where AC is the hypotenuse (longest side) and AB and BC are the other two sides

5^2 = 4.5^2 + BC^2

25 = 20.25 + BC^2

Subtract 20.25 from both sides of the equation

4.75 = BC^2

Add the square root sign to both sides of the equation

2.1794 = BC

Rounded up to the nearest tenth, the distance from the hook to the top of the frame will be 2.2 inches
