Answer:
n = 6
Step-by-step explanation:
Answer:
The answer is (4,2)
Step-by-step explanation:
in the point (-4,5) X=-4 AND Y=5
so if you move 8 units right, the X increases by 8(because the the x axis is left and right) so X transform into 4= -4+8=4
With Y(the y axis is up and down) whe u go 3 units down un decrease the number so Y transforms into 2== 5-3=2
The new coordiantes are(4,2)
Answer:
The answer is on point (3,1)
Answer:
(
, 
Step-by-step explanation:
Given the 2 equations
- 2x = 16 - 8y → (1)
x + 4y = 25 → (2)
Rearrange (2) expressing x in terms of y by subtracting 4y from both sides
x = 25 - 4y → (3)
Substitute x = 25 - 4y into (1)
- 2 (25 - 4y) = 16 - 8y ← distribute left side
- 50 + 8y = 16 - 8y ( add 8y to both sides )
- 50 + 16y = 16 ( add 50 to both sides )
16y = 66 ( divide both sides by 16 )
y = 
=
Substitute this value into (3) for corresponding value of x
x = 25 - 4 × )
= 
- 
=
Solution is ( , )
They are similar. Set the proportions equal to each other
(x + 8)/8 = (x+14)/12
Cross multiply
(x + 8)/8 (8)(12) = (x + 14)/12 (12)(8)
12(x + 8) = 8(x + 14)
Distribute the 12 and 8 to the corresponding monomials inside the parenthesis
12(x + 8) = 12x + 96
8(x + 14) = 8x + 112
12x + 96 = 8x + 112
Isolate the x. Subtract 8x from both sides and 96 from both sides
12x (-8x) + 96 (-96) = 8x (-8x) + 112 (-96)
12x - 8x = 112 - 96
4x = 16
Isolate the equal sign. Divide 4 from both sides
4x/4 = 16/4
x = 16/4
x = 4
