Answer:
y=2x-14
Step-by-step explanation:
Gradient as m(for 1st line m1 and m2 for 2nd line)
m1/m2=-1
m1=(-1)*(-2)=2
y-(-2)/x-6=2
y+2/x-6=2
y+2=2x-12
y=2x-14
Answer:
B
Step-by-step explanation:
Given the 2 equations
4x + 3y = 16 → (1)
7x + 6y = 31 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate the term in y
- 8x - 6y = - 32 → (3)
Add (2) and (3) term by term
- x = - 1 ( multiply both sides by - 1 )
x = 1
Substitute x = 1 in either of the 2 equations and solve for y
Substituting in (1)
4(1) + 3y = 16
4 + 3y = 16 ( subtract 4 from both sides )
3y = 12 ( divide both sides by 3 )
y = 4
Solution is (1, 4 ) → B
90 degrees
cuz if you look closely it says isosceles RIGHT triangle
A right triangle has a measure of 90 degrees
The answer is this:
y = 4/5x - 1
Only add 1 and 5 first, then your denominator would be 32 because 8 times 4 is 32.
