What is x2+10x=0 with completing the square

Mathematics
1 answer:
KengaRu [80]3 years ago
7 0
x^2 + 10x = 0 \\ 
x(x+10) = 0 \\ 
x = 0, -10
You can't complete the square here. You would have to separate an x out to get two values of 0 and 10.

Y = mx + b

m is your slope AKA rate of change
b is the y intercept.

from the graph we can see that the y intercept (b) is 15. (look at the y axis and see what point the line crosses on the y, here it is 15, in-between 10 and 20)

slope is rate of change. to figure this out remember slope = rise over run:

slope = \frac{rise}{run}

so pick two points. how much does one point rise after the other point you picked? In the graph it rises 1 square so rise = 1

Now looking at the same two points, how far away from each other are they on the x axis? Looking at the graph they are 2 squares away from each other. so run = 2

Now plug these numbers into the rise over run formula:

slope \: = \frac{1}{2}

Now we have everything we need to put into our formula for a line:

y = mx + b
y = \frac{1}{2} x + 18

For number 16 you should get:

y = \frac{1}{5} x + 3

after you do the same steps again yourself

Roland says the number of cups of iced tea t depends on the number of tea bags b. He says the equation represents the relationsh
nika2105 [10]

Answer:

I think Roland is correct in his statement.

Step-by-step explanation:

Roland says the number of cups of iced tea t depends on the number of tea bags b and he says the equation represents the relationship between the number of tea bags b and the cups of iced tea t = \frac{b}{1.5}.

I think Roland is correct in his statement and this is because here t is a function of b i.e. t = f(b) and hence, the number of cups of iced tea t depends on the number of tea bags b. (Answer)

Use inverse operations to solve the following:<br> 4.9 + z = -9
ale4655 [162]

The answer is z = -13.9

In order to solve this, you need to use inverse operations. The inverse operation of addition is subtraction. So, this is the function we'll use

4.9 + z = -9 ----> subtract 4.9 from both sides

z = -13.9
