How do I solve equations with a variable to the power of something (give steps please)
Like these.
[tex]2x^2+5x=0[/tex]
Answer:
Step-by-step explanation:
Factoring will reveal the solution. So we divide the equation by the greatest common factor of the terms and use that factor as the coefficient. In this case the greatest common factor is just x.
2x^2+5x
x(2x+5) so the equation will equal zero when either of those expressions is zero because zero times anything is zero. x=0 and x=-5/2
Answer:
[tex]x = 0, -\frac{5}{2}[/tex]
Step-by-step explanation:
First move all terms to one side of the equation to set them equal to 0
That is already done in your problem
The try to factor, if possible. In your case, factor out x
x(2x + 5) = 0 Now, use the property that says if AB = 0, then A = 0 or B = 0 or both A and B equal 0
So, x = 0 or 2x + 5 = 0
2x = -5
x = [tex]-\frac{5}{2}[/tex]
Always check your results in the original equation to see if they work
[tex]2(0^{2} + 5(0) = 0 + 0 = 0\\[/tex]
and [tex]2(-\frac{5}{2} )^{2} + 5(-\frac{5}{2} )\\ = 2(\frac{25}{4} ) - \frac{25}{2} \\ = \frac{25}{2} - \frac{25}{2} = 0[/tex]
Both results make the equation true, so [tex]x = 0, -\frac{5}{2}[/tex]

Answer:
The equation is:
y = -15*x + 1200
and:
a = 120
b = 70
c = -1500
Step-by-step explanation:
This seems to be a linear relationship.
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Here we know that our line passes through the points (60, 300) and (20, 900)
Then the slope of this line is:
a = (900 - 300)/(20 - 60) = 600/(-40) = -15
Then this line is something like:
y = -15*x + b
To find the value of b, we know that this line passes through the point (60, 300) then when x = 60, we have y = 300.
Replacing these values in the above equation we get:
300 = -15*60 + b
300 + 15*60 = b = 1200
Then:
y = -15*x + 1200.
Now that we have this equation, we can complete the table.
a is the value for y, when x = 72
Then we can replace x by 72 in the above equation:
a = -15*72 + 1200 = 120
a = 120
b is the value of x when y = 150, then we need to replace y by 150
150 = -15*b + 1200
150 - 1200 = -15*b
(150 - 1200)/-15 = b = 70
then:
b = 70
c is the value of y when x = 180, then we need to replace x by 180.
c = -15*180 + 1200
c = -1500

Answer:
Angles in a triangle are sum up to 180 degrees.
35 + 110 + (x+12)=180

What’s the equation? Please answer! Will give brainliest!!!
Answer:
y=x+10
Step-by-step explanation:
it's a guess. it goes up 1 over 1 so the "m" in y=mx+b has to be 1. so x stands alone. the line looks like it begins at 10 so the b will equal 10
Answer:
y = 5x + 10
Step-by-step explanation:
Line is passing through the points (2, 20) & (4, 30)
Slope of line (m) = (30 - 20)/ (4 - 2) = 10/2 = 5
y - 20 = 5(x - 2)
y = 5x - 10 + 20
y = 5x + 10

Which of the filling units are units of length
Answer:

Given that log_{a}(3) = 0.477 and
log_{a}(5) = 0.699, evaluate log_{a}(0.6) .
*The answer is -0.222 but I'm not sure how to do the steps.
Given:
[tex]\log_{a}(3) = 0.477,\log_{a}(5) = 0.699[/tex]
To find:
The value of [tex]\log_{a}(0.6)[/tex].
Solution:
We need to find the value of:
[tex]\log_{a}(0.6)[/tex]
It can be written as
[tex]\log_{a}(0.6)=\log_a\left(\dfrac{6}{10}\right)[/tex]
[tex]\log_{a}(0.6)=\log_a\left(\dfrac{3}{5}\right)[/tex]
By using the property of logarithm, we get
[tex]\log_{a}(0.6)=\log_a(3)-\log_a(5)[/tex] [tex][\because \log \dfrac{a}{b}=\log a-\log b][/tex]
[tex]\log_{a}(0.6)=\log_a(3)-\log_a(5)[/tex]
On substituting the given values, we get
[tex]\log_{a}(0.6)=0.477-0.699[/tex]
[tex]\log_{a}(0.6)=-0.222[/tex]
Therefore, the values of [tex]\log_a(0.6)[/tex] is -0.222.

Find the slope
Answer:
slope = 4/11
Step-by-step explanation:
To find the slope, use delta y/ delta x
(4,6) (-7,2)
(2-6)/(-7-4)
(-4)/(-11)
slope = 4/11
Let m = slope
m = difference of y-values divided by the difference of x-values.
m = (2 - 6)/(-7 - 4)
m = -4/-11
m = 4/11

If gas costs $2.85 per gallon, how many whole gallons of gas could you buy with $30.00?
Answer:
11
Step-by-step explanation:
We can buy 10 gallons of gas with $30, whose unit price is $2.85.
What is unit rate?The rate calculated for one quantity of something is called unit rates.
Given that, the gas costs $2.85 per gallon, we need to find how many whole gallons of gas could you buy with $30.00.
Let the x gallons cost $30.00
Therefore,
2.85x = 30
x = 30 / 2.85
x = 10.52
x ≈ 10
Hence, we can buy 10 gallons of the gas from $30.

Answer:
the answer is c 1.2
Step-by-step explanation:
to calculate the iqr you have to do the following:
q3 - q1 = answer
4.5 - 3.3 = 1.2
The IQR(interquartile range) for the distribution of the song length is 1.2.
What is interquartile range(IQR)?Interquartile range gives information on the spread of the middle half of your distribution.
Mathematically, the interquartile range can be represented as follows:
IQR = Q₃ - Q₁
where
Q₃ = 4.5
Q₁ = 3.3
Therefore,
IQR = 4.5 - 3.3
IQR = 1.2
Therefore, the interquartile range is 1.2.
