Y - y₁ = m(x - x₁)
y - 6 = 7(x - (-4))
y - 6 = 7(x + 4)
y - 6 = 7(x) + 7(4)
y - 6 = 7x + 28
<u> + 6 + 6</u>
y = 7x + 34
Answer:
Option C.
Step-by-step explanation:
we know that
If a system of two linear equations has an infinite number of solutions, then both equations must be identical
The given equation is
<u><em>Verify each case</em></u>
Option A. we have
apply distributive property
Compare with the given equation
Option B. we have
remove the parenthesis
Compare with the given equation
Option C. we have
apply distributive property
Compare with the given equation
therefore
This equation with the given equation form a system that has an infinite number of solutions
Option D. we have
Compare with the given equation
Answer:
x=53
Step-by-step explanation:
pythagoras theorem
a^2 + b^2 =c^2
here a and b are two small sides and c is hypotenuse (longest side)
28^2 + 45^2 = c^2
784 + 2025 =x^2
2809 =x^2
=x
53 =x
$48/x 25%/100
48 x 100= 4800
4800 / 25= 192
answer: $192
It is 600
