Help i dont remember dis stuff from last year
1 answer:
See below for the solution to the systems of equations
<h3>How to solve the systems of equations?</h3><u>System of equations 1</u>
Here, we have
3x - 4y = -16
3x + 4y = 8
We start by plotting the graph of both equations
Next, we write out the point of intersection of the equations
See attachment for the equation of the system
From the attached graph, the point of intersection of the equations is (-4/3, 3)
Hence, the solution to the system is (-4/3, 3)
<u>System of equations 2</u>
Here, we have
-x = - 6 + 2y
-18 + 6y = -3x
We start by plotting the graph of both equations
Next, we write out the point of intersection of the equations
See attachment for the equation of the system
From the attached graph, both lines are on each other
This means that the system of equations have infinite many solutions

Answer:
<h2>17/35</h2>Step-by-step explanation:
We need to get all the fractions with a common denominator before we can solve the problem.
The only fractions that have a common multiple are 1/7 and 3/21, so we'll add these first and then add 1/5.
1/7 = 3/21
Add
6/21 = 30/105
1/5 = 21/105
Simplify
I'm always happy to help :)
Answer:
4 pounds of strawberries and 5 pounds of apples are bought.
Step-by-step explanation:
Given:
Total number of pounds of fruit = 9 pounds
Total money spent = $16.35
Cost of 1 pound of strawberry = $1.60
Cost of 1 pound of apple = $1.99
Let 'x' pounds of strawberries and 'y' pounds of apples are bought.
So, <u><em>as per question:</em></u>
<em>The sum of the pounds is 9. So,</em>
Now, total sum of the fruits is equal to the sum of 'x' pounds of strawberries and 'y' pounds of apples. So,
Now, plug in the 'y' value from equation (1) in to equation (2). This gives,
Now, from equation 1, we have:
Therefore, 4 pounds of strawberries and 5 pounds of apples are bought.
