Answer:

[tex]\huge\boxed{-13, 21}[/tex]

Step-by-step explanation:

The most common way to solve for the roots of a polynomial is to use the Quadratic formula, which will return us with two values of x that make the equation equal 0.

...however, this form of the equation is already in root form. If we multiplied these two terms, we'd get [tex]x^2 - 8x -273[/tex], and when we factor that, we'd get -13 and 21.

Roots are usually written in the form [tex](x-a)(x-b)[/tex], where the zeroes will be the value of x that makes each binomial equal 0 - aka, the opposite of a and b.

The opposite of 13 is -13, and the opposite of -21 is 21.

Therefore, the solutions of this equation are -13 and 21.

Hope this helped!

Answer:

819

Step-by-step explanation:

We solve the above question using simple interest

The formula for the total amount in a bank amount when it earn simple interest annually is:

A = P(1 + rt)

When

P = Initial amount in the account = 780

r = Simple Interest rate = 2.5% = 0.025

t = 2 years

A = 780(1 + 0.025 × 2)

A = 780(1 + 0.050)

A = 780(1 .050)

A = 819.00

The amount of money that will be in her account if she does not make any deposits or withdrawals in 2 years is 819.

Answer:

[tex]\frac{m}{6}[/tex] = -9            6 × (-9) = -54

Step-by-step explanation:

Answer:

m<1 = 79°

Step-by-step explanation:

12x + 19 + 22x - 9 = 180

add the numbers

34x + 10 =180

minus 10

34x = 170

divide by 34

x = 5

plug 5 into the equation of angle 1

12(5) + 19 =

Answer:

Approximately 45%.

Step-by-step explanation:

We know that Steve's team played in total 33 games. Out of the 33, they won 15 of them.

So, as a fraction of the total won over the total games, we can write:

[tex]\displaystyle\frac{15}{33}[/tex]

So, by dividing, the percent the team won is:

[tex]\displaystyle\frac{15}{33}=0.\overline{45}=0.454545...\approx0.45=45\%[/tex]

The team won approximately 45% of its games.

Answer:

I believe the answer would be 4 :) hope this helps

the answer is definitely 4

Answer:

If you're multiplying them: 34x * 30x = 1020x^2

If you're adding them: 34x + 30x = 64x

If you're subtracting them: 34x - 30x = 4x

Answer:

4m-8

Step-by-step explanation:

answer

Answer:

4m - 8

Step-by-step explanation:

Given expression,

→ m - (8 - 3m)

Simplifying the expression,

→ m - (8 - 3m)

→ m - 8 + 3m

→ 4m - 8

→ 4(m - 2)

Hence, answer is 4m - 8.

Answer:

f=gx−3/x−5

Step-by-step explanation:

Step 1: Flip the equation.

fx−5f+3=gx

Step 2: Add -3 to both sides.

fx−5f+3+−3=gx+−3

fx−5f=gx−3

Step 3: Factor out variable f.

f(x−5)=gx−3

Step 4: Divide both sides by x-5.

f(x−5)/x−5=gx−3/x−5

Answer:

x = 4

Step-by-step explanation:

2x − y = 11      ⇒    -y = - 2x +11     ⇒      y = 2x - 11

x + 3y = -5

x + 3(2x - 11) = -5

x + 6x - 33 = -5

      +33       +33  

7x = 28

x = 4

The solution of x in the system of linear equations is x = 4

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

2x - y = 11   be equation (1)

x + 3y = -5   be equation (2)

Multiply equation (1) by 3 , we get

6x - 3y = 33   be equation (3)

Adding equation (2) from equation , we get

7x = 28

Divide by 7 on both sides , we get

x = 4

Hence , the equation is solved and x = 4

Answer:

y = 2x-4

all the equations are the same as the slope-intercept form is the same for all the equations

Step-by-step explanation:

slope-intercept form:

[tex]y = mx + b[/tex]

2x-3 = y+1

-y+2x-3 = 1

-y = 1-2x+3

-y = (1+3)-2x

-y = 4-2x

y = -4+2x

( commutative property: the number on which we operate can be moved or swapped from their position without making any difference to the answers )

y = 2x-4

Answer:

0.2-0.05=0.15

Step-by-step explanation:

0.2=0.20

0.20-0.05=0.15

The required difference between 0.2 and 0.05 is 0.15, which is determined by the subtraction operation.

To find the difference between 0.2 and 0.05, we subtract 0.05 from 0.2:

0.2 - 0.05 = 0.15

The difference between 0.2 and 0.05 is 0.15.

When subtracting decimals, we align the decimal points and subtract each place value. In this case, both numbers have one decimal place, so we subtract the tenth place.

Starting from the right, we have 0 in the tenth place of 0.2 and 0 in the tenth place of 0.05. Subtracting 0 from 0 gives us 0.

Therefore, the difference in the tenth place is 0.

Since there are no other place values to subtract, the resulting difference is 0.15.
