Answer:
x = -2.5
x = 2
Step-by-step explanation:
Hello!
We can remove the denominators by multiplying everything by it.
Solve:
Let's make one side equal to 0.
Solve by factoring, and then the zero product property.
Multiply 2 and -10. You get -20. Think of two number that multiply to -20, and add to 1. If we think about the standard form of a quadratic, , think two numbers that equal "ac" and add up to "b".
Using the zero product property, set each factor to 0 and solve for x.
- 2x + 5 = 0
2x = -5
x = -5/2 = -2.5 - x - 2 = 0
x = 2
The two answers are x = -2.5, and x = 2.
A+b+c=28x+40=180
—>28x=140
—>x=140/28=5
c=9x-3
—>c=42

<em>5 to the 2nd power times 5 to the 2nd power is equivalent to 625</em>
<h2>
Explanation:</h2>
In this case, we have the following statement:
<em>5 to the 2nd power times 5 to the 2nd power. </em>In a mathematical language:
From product rules, we know that:
Applying this rule to our problem:
<em>5 to the 2nd power times 5 to the 2nd power is equivalent to 625</em>

Answer:
They have the same slope
Step-by-step explanation:
The standard equation of a line in point-slope form is expressed as;
y-y0 = m(x-x0)
We can see that both equations given are written in this form with a slope of 1.2. For two lines to be equal, they must have the same slope no matter the point on the lines. Hence the two equations are equal since they have different slopes.
