Answer:
(5, 2)
Step-by-step explanation:
Lets substitute y = -x + 7 into 4x-5y=10
Then we can write 4x-5y=10 as 4x-5×(-x+7)=10,
4x-(-5x)-35=10
9x-35=10
9x=45
x=5, therefore, y= -5+7=2
From the description we can see that Lines EF and GH are the bases.
The median = the sum of the bases divided by 2.
median = (7 + 24) / 2 = 31/2 = 15.5 cm
We need to write the given statement in math terms:
y increased by 4
Recall that increased means that we are adding 4 to the previous number.
Then the mathematical expression is:
y + 4
The quantity y has been increased by 4 units.
