2 answers:

6 0

For these ones I just play around with what I can divide 84 by to equal -33 in the middle. I decided to divide 84 by 4 because it was an even number.

84/4=21

21+ (3*4)= 33

Answer: (x-4)(3x-21)

Answer: The factors of the given expressions are 3, (x-7) and (x-4).

Step-by-step explanation: We are given to find the factors of the following quadratic expression :

$E=3x^2-33x+84~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

To find the factors of the given expression, we need to find two integers with sum -33 and product 252.

From (i), we have

$E\\\\=3x^2-33x+84\\\\=3x^2-21x-12x+84\\\\=3x(x-7)-12(x-7)\\\\=(x-7)(3x-12)\\\\=3(x-7)(x-4).$

Thus, the factors of the given expressions are 3, (x-7) and (x-4).

If the vertices of the triangle are J(-3,-5), K(-2,2) and L(1,-4) then its reflection in y axis are J(3,-5), K(2,2) and L(-1,-4)

Given,

The vertices of the triangle = J(-3,-5), K(-2,2) and L(1,-4)

We know,

In reflection in y axis (x,y) will become (-x,y)

Then the vertices of the reflection in y axis = J(3,-5), K(2,2) and L(-1,-4)

Draw the triangle using the vertices.

Hence, if the vertices of the triangle are J(-3,-5), K(-2,2) and L(1,-4) then its reflection in y axis are J(3,-5), K(2,2) and L(-1,-4)

Matthew earned $75 in interest on

tensa zangetsu [6.8K]

Answer:

Step-by-step explanation:

The formula for simple interest is

I = Prt,

where I is the interest earned,

P is the initial investment amount,

r is the interest rate in decimal form, and

t is the time in years. For us,

I = 75,

P = ?

r = .05

t = 1

Filling in what we were given:

75 = P(.05)(1) and

.05P = 75 so

P = 1500

20x - (-2x) + (-16) = 6 Solve for X

lianna [129]

Answer:

Step-by-step explanation:

x = 1

Step 1: Simplify both sides of the equation.

20x−−2x−16=6

20x+2x+−16=6

(20x+2x)+(−16)=6(Combine Like Terms)

22x+−16=6

22x−16=6

Step 2: Add 16 to both sides.

22x−16+16=6+16

22x=22

Step 3: Divide both sides by 22.

22x

Find the z-score that has 62.8% of the distribution's area to its right.

horrorfan [7]

The best and easiest way to get it is by using a TI calculator and i hope you can have it, then you can type in the next: invnorm(1 - 0.628) What you are doing is that you are subtracting the probability from 1 because the invnorm function finds the z-score given the probability to the left of the z-score. I think that can help you.
