solve by factoring
x^2 -10 = 9x

Answers

Answer 1

Answer:

(10,0)(-1,0)

Step-by-step explanation:

x^2 - 9x - 10 = 0

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

The two solutions are

x - 10 = 0

x = 10

or

x+1 = 0

x = - 1

Answer 2

Answer:

x=10, x=-1

Step-by-step explanation:

Hi there!

We are given this equation:

x²-10=9x

And we want to solve it by factoring

Factoring is easier to do when all of the terms are on the same side, so let's subtract 9x from both sides

x²-9x-10=0

Now we must think of two numbers that add up to -9, but multiply to get -10

Those numbers are -10 and 1

So factor the polynomial using FOIL:

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

Now split and solve via the zero product property:

x-10=0

Add 10 to both sides

x=10

x+1=0

Subtract 1 from both sides

x=-1

Hope this helps!

B. y=1/8x; 1.25 feet
C. y=8x; 80 feet
D. y=6x; 60 feet

Answers

The answer to this question is letter C

We can approach this by first finding the rate of feet per second traveled.

240(feet)/30(seconds)= 8 feet per second.

This answer resembles the slope for answer choice C.

To find the distance traveled in 10 seconds we do 10*8= 80 feet.

Answer:

28800 apples in 2 hours

Step-by-step explanation:

20 apples / 5 seconds

Divide the top and bottom by 5

4 apples/ second

A few hours is 2 or 3

There are 3600 seconds in 1 hour

4 apples/ second * 3600 seconds / 1 hour = 14400 apples / hour

14400 apples/ hour

14400apples / hour * 2 hours

28800 apples in 2 hours

Answer:

4 apples per second; about 14400-43200 apples

Step-by-step explanation:

First, to find the unit rate, you need to divide the number of apples with the number of seconds...

20/5= 4 apples per second

Then, to find the number of apples being packed after a few hours, you multiply the unit rate of apples by the total amount of seconds...

(4)(3600) = 14400 apples

(4)(10800) = 43200 apples

And so on and so forth depending on the number of hours they need (remember to convert the hours into seconds and multiply by 4)

Answer:

-3r + 15 ---> answer

Step-by-step explanation:

r < 5

You are going to multiply both sides with 3. The reason being is that 3 is a positive number and the equality sign will not change if you use +3.

3r < 15

Now, subtract 15 from both sides, you will get this:

3r < 15

-15   -15

-------------

3r — 15 < 0

Lastly, using the Modulus function, we are going to add a negative sign to the content of our previous step because it's already negative.

So, -3r + 15 is the final solution if r < 5 in the given equation of l3r-15l

What is algebra?

A part of mathematics in which letters and other general symbols are used to represent numbers and quantities in formulae and equations.

Given that:

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

4 1/5 ÷ 1 1/5 = 11 - 1 7/18x

convert into simple fraction form, we get

21/5 ÷ 11/5=11-17x/18

convert  divide into multiply

21/5*5/11=11-17x/18

cancel out 5 from numerator and denominator, we get

21/11=11-17x/18

same form are in same side

17x/18=11-21/11

after simply, we get

17x/18=121-21/11

17x/18=100/21

cross multiplication on both sides and find x,we get

x=100*18/21*17

x=5.04

So, the solution of given equation is 5.04.
