Answer:

[tex]x > 8[/tex]

Step-by-step explanation:

1. Simplify the expression

Expand the parentheses:

[tex]-2*2x-2*-3<-26[/tex]

Simplify the arithmetic:

[tex]-4x+6<-26[/tex]

2. Group all constants on the right side of the inequality

Subtract 6 from both sides:

[tex]-4x+6-6<-26-6[/tex]

Simplify the arithmetic:

[tex]-4x<-26-6[/tex]

Simplify the arithmetic:

[tex]-4x<-32[/tex]

3. Isolate the x

Divide both sides by-4:

When dividing or multiplying by a negative number, always flip the inequality sign:

[tex]\frac{-4x}{-4} >\frac{-32}{-4}[/tex]

Cancel out the negatives:

[tex]\frac{4x}{4} >\frac{-32}{-4}[/tex]

Simplify the fraction:

[tex]x>\frac{-32}{-4}[/tex]

Cancel out the negatives:

[tex]x>\frac{32}{4}[/tex]

Find the greatest common factor of the numerator and denominator:

[tex]x>\frac{8*4}{1*4}[/tex]

Factor out and cancel the greatest common factor:

[tex]x>8[/tex]

4. Solution on a coordinate plane

Solution:

[tex]x>8[/tex]

Interval notation:

Step-by-step explanation:

104         x

----      =  ---

50          60

Cross multiply 104 by 60. 6240 is your answer.

Your new equation is 6240 = 50x.

Divide both sides by 50. 6240/50 = x

x = 124.8 mph (miles in one hour)

Answer:

Step-by-step explanation:

-39 = 18 + 4m

4m + 18 = -39

Subtract 18 from both sides

4m = -39 - 18

4m = -57

Divide both sides by 4

m = -57/4

Step-by-step explanation:

$1250 x (1-15%) = $1,062.50 Discounted Price

$1,062.50 x 6.5% = $69.06 Sales Tax

$1,062.50 + $69.06 = $1,131.56

Answer:

X, Y, Z are collinear

Step-by-step explanation:

X,Y,Z lie on the same straight line

The slope of the lines are the same thus line m and n both passes through X, Y, and Z points and thus all three points will be colinear.

A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.

Slope = Tanx where x will be the angle from the positive x-axis at that point.

Given that line m is passing →

Points X and Y

Line n passing →

Points X, Z

The slope of m = slope of n

If the slope same then the line will be parallel and since both lines are passing through the same point X thus they will be a colinear line.

All points that lie on the colinear line are colinear points.

Hence "X, Y, and Z all three points will be colinear".

Open circle at 10 and shade to the left.

Using a system of equations, it is found that the number of blue M&Ms in the package is of:

D. 105

In this problem, the variables are:

There are 305 M&Ms, hence:

[tex]x + y + z = 305[/tex]

There are three times as many red as white, hence:

[tex]x = 3y[/tex]

[tex]x + y + z = 305[/tex]

[tex]3y + y + z = 305[/tex]

[tex]4y + z = 305[/tex]

The blue are five more than twice the white, hence:

[tex]z = 5 + 2y[/tex]

Then:

[tex]4y + z = 305[/tex]

[tex]4y + 5 + 2y = 305[/tex]

[tex]6y = 300[/tex]

[tex]y = \frac{300}{6}[/tex]

[tex]y = 50[/tex]

[tex]z = 5 + 2y = 5 + 2(50) = 105[/tex]

Hence option D is correct.

Answer:

(X+1) (x - 4) (x+2)

Step-by-step explanation:

All the coefficients are integers so apply the rational zeros theorem.

The coefficient of x^3 is 1.

Divide (x^3-x2-10x-8)(x+1) = x^2-2x-8 with remainder = 0

The remainder is 0. (x+1) is a factor.

(x + 1) ( x^2 - 2x - 8)

x^2 - 2x - 8 (-4 * 2= 8) and -4 + 2 = -2)

= (x -4) (x+2)

Step-by-step explanation:

Answer:

not factorable

Step-by-step explanation:

[tex]x^{2} - 9x +10\\[/tex]

The easiest way to factor is to find two numbers of the "a" value (the coefficient before [tex]x^{2}[/tex]) and the factors of the c value (10) that ADD up to give you -9, in this case it would be:

1          -10  --> 1(-10) gives you -10

1           -1    --> 1(-1) gives you -1

adding these together -10 + (-1) = -11 which does not equal -9.

You could stop here and conclude that this is not factorable by inspection.

Another method: using the quadratic formula to find its roots.

Roots: [tex](\frac{9-\sqrt{41} }{2}, 0)[/tex] and [tex](\frac{9+\sqrt{41}}{2}, 0)[/tex]

Answer:

20

Step-by-step explanation:

Assuming you are referring to the day that both teams would play on the same day, it would be the 20th.

There are two ways you can do it.

1. List out the multiples of each number

2. multiply the two days together

If you want to do it the first way it would look like this...

5 10 15 20

4 8 12 16 20

When you do it like this it shows you that the 20th day is the day they would both play together

If you want to do it the second way it would look like this...

4th day X  5th day = 20th day

Either way you solve the problem you get the same answer, this may not work for every problem like this, but it works for this particular one
