Answer:
(x+5y)(x+6y)
Step-by-step explanation:
Answer:
3x-4y=15
7x+y=4
Solve7x+y=4 for y:
7x+y=4
7x+y+−7x=4+−7x (Add -7x to both sides)
y=−7x+4
Step: Substitute −7x+4 for y in 3x−4y=15:
3x−4y=15
3x−4(−7x+4)=15
31x−16=15 (Simplify both sides of the equation)
31x−16+16=15+16 (Add 16 to both sides)
31x=31
(Divide both sides by 31)
x=1
Step: Substitute 1 for x in y=−7x+4:
y=−7x+4
y=(−7)(1)+4
y=−3(Simplify both sides of the equation)
Answer: x=1 and y=−3
Answer:
The answer is
Step-by-step explanation:
To find an equation of a line when given the slope and a point we use the formula
From the question we have
We have the final answer as
Hope this helps you
Answer:
C
Step-by-step explanation:
We have the equation:
Let's expand both sides. Distribute on the left:
Distribute on the right:
Combine like terms on the right:
Add 16x to both sides:
This is not true.
So, our equation has no solutions.
This would mean that our two linear equations are parallel to each other.
Our answer is C
Answer: top triangle = 10 x 4 = 40cm^2 / 2 = 20cm^2
Rectangle = 10 x 6 = 60cm^2
Right hand triangle = 6 x 4 = 24cm^2 / 2 = 12cm^2
Step-by-step explanation:
For top triangle we do 10 - 6 to get shortest side
Rectangle - ignore 14 and use top 10 cm
Finally triangle on right hand - do 14cm - 10 to get base side. Base side is 4cm.
Formula for area of triangle = b x h / 2
Note: ^2 is just to the power of 2 or squared
I hope u found this answer beneficial.
Have a nice day and Christmas holidays m8 :-)
