What’s the answer to this

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:

$200

Step-by-step explanation:

Change 15% into decimal notation, that will give you 0.15

Divide $30 by 0.15

$30/0.15 = $200

Answer:

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)

Step-by-step explanation:

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

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".

x=13

Step-by-step explanation:

Switch sides:

2x−9=17

Add 9 to both sides:

2x−9+9=17+9

Simplify

2x=26

Divide both sides by 2:

2x/2 =26/2

Simplify to get the result.

x=13

Answer:

x=13

Step-by-step explanation:

[tex]\sf 2x-9=17[/tex]

[tex]\sf 2x-9+9=17+9[/tex]

[tex]\sf 2x=26[/tex]

[tex]\sf \cfrac{2x}{2}=\cfrac{26}{2}[/tex]

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:

[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:

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)
