Answer:
y = -7/4x
Step-by-step explanation:
This is correct because to find the perpendicular, you need to find the opposite reciprocal of the slope. In this case, the slope is 4/7, so the opposite reciprocal is -7/4.
Answer:
Step 2 has error and step 4 has error.
Step-by-step explanation:
Here we can see that elimination method is applied to solve the system of equations for which -2 is multiplied both sides of equation first
-2(x+2y)=-2(10 which is correct
but in step 2
left side is -2x-4y and the right side is -10 which has to be -20 which makes this step wrong and this is the error made by student.
in Step 4 also ,value of the y has to be 5 but student plugged y =1 which is also error by student.
Correct solution is
-2x-4y= -20
2x+ 5y= 15
on adding ,we get
y = -5
plugging y =5 in equation x+2y= 10 ,we get x+2(-5) =10 ,we get x = 20
therefore (20,-5) is the solution
Answer:
In each of the 4 smoothies there will be 
of orange juice.
Step-by-step explanation:
Given:
Number of gallons of orange juice = 
Number of friends = 4
We need to find the gallon of orange juice will be in each of the 4 smoothies.
Solution:
To find the gallon of orange juice will be in each of the 4 smoothies we will divide Number of gallons of orange juice with Number of friends.
framing in equation form we get;
gallon of orange juice will be in each of the 4 smoothies = 
Hence in each of the 4 smoothies there will be of orange juice.
You should multiply 0.33 by 6 and it should equal 1.98 liters.
Answer: y = - 3 
x + 500
Step-by-step explanation:
First, we will start off with y = since y is the amount of money left to spend.
Next, we see that three invitations cost $10. $10 / 3 = 3 . One invitation will cost $3
Lastly, we will create our final equation in slope-intercept form:
y = - 3 x + 500
<em> Side Note: We also could write something like y = -10(</em>
<em>) + 500 if we did not want to change the cost.</em>
