Answer:
(1, -8)
y= -8
x= 1
Step-by-step explanation:
7x-3y= 31
7x+y= -1
solve the equation
7x-3y=31
7x= -1-y
substitute the value of 7x into an equation
-1-y-3y=31
subtract -y to -3y
-1-4y=31
add both sides by 1
-4y=32
divide both sides by -4
y= -8
substitute the value of y into an equation
7x= -1-(-8)
distribute
7x=7
divide both sides by 7
x=1
(1, -8)
Answer:
-11, 11
Step-by-step explanation:
You have to find when the function crosses the x-axis. You could find this using algebra by solving for x in the equation but I prefer to simply graph it using something like desmos and see when it crosses the x-axis. Doing that I can see the answers would be -11 and 11
You can multiply a fraction with the same numerator and denominator like 2/2, which is also one (does not change original fraction).
6/9*2/2= 12/18
or any other number
6/9*3/3=18/27
8 strawberries : 32 strawberries
1:4
This is the Ratio so
5 bananas : 20 bananas
6 apples : 24 apples
2 pears : 8 pears
He should use 20 bananas , 24 apples and 2 pears.
