Answer:
c)
Step-by-step explanation:
The way I solve these is...
First, you look at where the line crosses the y-axis because that's your b in the y=mx+b equation. Which is 9
Then I find a point where the line passes thru so for example, (-6,5) Remember that x point is always before the y.
From there I determine if the line is positive or negative, this one's positive because the line goes up from left to right, if it were going up from right to left, then it'd be negative.
So knowing it's positive we count the points up and to the right until reaching the next point. So first go up 2 points and then right 3.
Knowing this, remember that it's always rise over run for the slope, so we rose 2, and ran 3. so, the slope is 2/3
This gives us our equation of
Answer:
The amount that Obi initially had was £20
Step-by-step explanation:
Let
x ----> amount that Obi initially has
y ----> amount that Rudy has
we know that
----> equation A
----> equation B
Solve the system by substitution
substitute equation A in equation B
solve for y
Find the value of x
therefore
The amount that Obi initially had was £20
Answer:
Yes
Step-by-step explanation:
You can find the answer to this question by finding the value of x in both equations.
Let's start off with the first equation:
To find the value of x, you're going to have to subtract 4 from both sides. This is because you're looking for the value of only x, not x + 4. To leave x alone, you'd have to subtract 4, leaving that side with just x.
The answer to the first equation is x = 1.
Now let's start on the second equation:
Like before, you're looking for x alone and in this equation, 8 is being added to 2x. Although x itself isn't alone, you'll first start off with 2x since you can simplify it thrughout the process. In this equation, you're going to subtract 8 from both sides to leave the variable x alone.
Now you're left with 2x = 2. Since you're looking for the value of x alone, you're going to divide both sides by 2. Because x is being multiplied by 2(2 times x = 2x) you're going to divide(opposite of multiply), which will cancel out the 2(in 2x).
The answer to the second equation is x = 1.
<em> Since both equations have the same solution, the answer to your question would be </em><em>yes</em><em>.</em>
