Answer:

1) x = -1 or x = -10 (either of them are both correct)

2) x = 3 or x = -5

Step-by-step explanation:

Let's solve your equation step-by-step.

x2 + 11x + 10 =0

Step 1: Factor left side of equation.

(x + 1)(x + 10) = 0

Step 2: Set factors equal to 0.

x + 1 = 0 or x +10 = 0

x = −1 or x = −10

Answer:

x = −1 or x = −10

2x^2 + 4x − 30 = 0

Answer:

x = 3 or x = −5

Answer:

Interpreting as: 2(a+b)=-8.1

Input:

2 (a + b) = -8.1

In Given the expression

                               2( a + b) = 8.1  ..........................(1)

now divide both sides of the first equation by 2 ,

                         2 (a + b) /2 = 8.1 /2

                        (a + b) = 4.05

expression    -0.5(a + b) ................(2)

 simply put the value of (a + b) in (2),

                          - 0. 5( 4.05) = -0.5 * 4.05

                                          = 2.025

Value of expression is 2.025.

An expression is a set of terms combined using the operations +, – , x .

For example - 4 x − 3 or x 2 – x y + 17 .

Answer:

( 0,-8) is the y intercept

Step-by-step explanation:

y = -3x -8

This is in slope intercept form

y = mx+b where m is the slope and b is the y intercept

-3 is the slope and -8 is the y intercept

( 0,-8) is the y intercept

Answer:

Missing value is -4/3 and whole solution can be written as  ( 8,-4/3)

Step-by-step explanation:

Given equation 2x+3y=12

solution ( 8,)

solution is form (x,y) hence in (8,) x is given as 8 while y  is missing to find y

we will plug 8 as value of x in equation  2x+3y=12. From this equation we will find the missing value.

2x+3y=12

=> 2*8+3y=12

=> 16 + 3y = 12

=> 3y = 12-16= -4

=> y = -4/3

Thus, missing value is -4/3 and whole solution can be written as  ( 8,-4/3)

Answer:

98

Step-by-step explanation:

(2a + [tex]\frac{1}{2a}[/tex] )² = 4a² + 2 + [tex]\frac{1}{4a^2}[/tex] , thus

10² = 4a² + 2 + [tex]\frac{1}{4a^2}[/tex] ( subtract 2 from both sides )

100 - 2 = 4a² + [tex]\frac{1}{4a^2}[/tex] , that is

4a² + [tex]\frac{1}{4a^2}[/tex] = 98

Answer:

x = 24.

Step-by-step explanation: given lines s and t are parallel and line m is a bisector, we can conclude that (2x+27) is an opposite exterior angle and congruent to the angle adjacent to (4x+9).  Defining those 2 angles are supplementary, they = 180 degrees.  Therefore, 2x+27+4x+9=180.  Subtract 36 (27+9) from the left side of the equation as well as from the right side (180-36) you get 2x+4x=144.  Add the x's you get 6x.  So, 6x=144.  Divide both sides by 6 and you get x=24.

The next step is to find the point on the circle which makes a tangent line that passes through the outside point.

Step-by-step explanation:

A tangent line to a circle is a line that touches the circle at exactly one point. You need two points to draw a line. You already have one point and the circle, then you need the other point, which lies on the circle. These two points have to lie on the same line. Notice that there are two possible tangent lines.

Answer:

connect the center of the circle to the point outside the circle

Answer:

D.

Step-by-step explanation:

area of a square = side^2

area of a cube = 6 x side^2

let the side be a .

6a^2 = 600

=> a^2 = 600/6

=> a^2 = 100

Hence the area of one of its faces is 100 square inches.

or in plain terms without using those formulas,

6 faces of the cube have 600 square inches

=> 1 face of the cube has 600/6 = 100 square inches

Answer: 20 servings

Step-by-step explanation:

From the question, Sara is having a dinner party for four friends and she needs to reduce the serving size of the meatloaf recipe. Sara used the equation x/4=5 . To get the number of servings the recipe originally made, we have to find the value of x.

x/4 = 5

x = 4 × 5

x = 20

This means that the recipe that was used originally made 20 servings.

y>1.5x+3

Step-by-step explanation:

All you need to do is isolate y, no coefficients, using basic algebra.

3x-2y<-6

-3x both sides

-2y<-3x-6

divide by -2 and switch the comparing sign to the other direction.

y>1.5x+3

Answer:

y > 3/2x +3

Step-by-step explanation:

3x-2y<-6

Subtract 3x from each side

3x-3x-2y<-3x-6

-2y< -3x-6

Divide each side by -2, remembering to flip the inequality

-2y/-2 > -3/-2x -6/-2

Step-by-step explanation:

Answer:

w⁴ - 36

=> ( w² )² - ( 6 )²

=> ( w² + 6 ) ( w² - 6 )

=> w² + 6 = 0 and w² - 6 = 0

=> w = √-6 and w = √6

The value of w is √-6 and √6 .

An identity is an equation that is true for all values of the variables.

For example:

The above equation is true for all possible values of x and y, so it is called an identity.

According to question one such identity will be used

[tex]a^{2} - b^{2} = (a+b)(a-b)[/tex]

w⁴ - 36

= ( w² )² - ( 6 )²

= ( w² + 6 ) ( w² - 6 )

= w² + 6 = 0 and w² - 6 = 0

= w = √-6 and w = √6

Hence, w is a quadratic term so it have two value √-6 , √6 .
