Answer:
y=6x-76
Step-by-step explanation:
the information given is really nice because in order to write a linear equation linear we need 4 information:
at least one coordinate pair satisfy the line(if slope wasn't given then we need at least two)
The rate of change (slope)
And lastly the initial value(y-int)
in this case:
x:11 y:-10 slope(m):6 b=?
so I plug to solve to b
-10=6(11)+b
clearly b is -76
put it back into y=mx+b form
our final answer is going to be
y=6x-76
Answer:
The solution for the given expression is 0 , 2
Step-by-step explanation:
Given expression as :
- x² + x = 0
or, - 2 x² + 4 x = 0
or, 2 x ( -x + 2 ) = 0
or, ( - x + 2 ) ( 2 x ) = 0
or, 2 x = 0
∴ x = 0
and ( - x + 2 ) = 0
Or, - x = - 2
∴ x = 2
Hence The solution for the given expression is 0 , 2 Answer
So dad is represented by x
son is represented by y
so x is (x=) 7 times his son (7y)
our first sentence is x=7y
10 years later (x+10, y+10) he will be 3 times as old as his son (x+10=3(y+10))
or 10+x=3(y+10)
so our sentences are
x=7y
and
x+10=3(y+10)
first we subsitute x=7y for x in the second equation
(7y)+10=3(y+10)
7y+10=3(y+10)
we distribute
7y+10=3y+30
subtract 3y from both sides
4y+10=30
subtract 10 from both sides
4y=20
divide both sides by 4
y=5
the son is currently 5 years old
x=7y
subsitute y=5 for y in equation
x=7(5)
x=35
the dad is currently 35 years old
in 10 years
dad is 45 and son is 15
dad=35
son=5
Answer:
40%
Step-by-step explanation:
According to the given description of the 10 by 10 grid, 40 out of 100 squares are shaded.
Convert into a Fraction:
Convert the fraction into a decimal:
Convert the decimal into a percent:
<u>40%</u>
<u></u>
So, the grid should represent 40%.
