Answer:
Taking (x,y) into account, here's the math.
Step-by-step explanation:
We know x is the horizontal line, so it will be moving to the left or right, while y is the vertical, meaning it will move up or down.
If we do x-7, that means we're moving towards the left 7 times, or in other words, closer to the negative side.
If y is +1, then that means we'll be moving up 1, closer to the positives.
So, your answer would be,
<u>Left 7 units and up 1 unit.</u>
Answer:
option 4
Step-by-step explanation:
using the sine/ cosine ratios in the right triangle and the exact values
cos30° = 
, sin30° = 
, then
cos30° = 
= 
= ( cross- multiply )
2x = 20
× = 20 × 3 = 60 ( divide both sides by 2 )
x = 30
and
sin30° = 
= 
= ( cross- multiply )
2y = 20 ( divide both sides by 2 )
y = 10
Simplifying
7x + 2y = 16
Solving
7x + 2y = 16
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
7x + 2y + -2y = 16 + -2y
Combine like terms: 2y + -2y = 0
7x + 0 = 16 + -2y
7x = 16 + -2y
Divide each side by '7'.
x = 2.285714286 + -0.2857142857y
Simplifying
x = 2.285714286 + -0.2857142857y
Answer:
x=8, y=25. As a point it's (8,25)
Step-by-step explanation:
here is the system:
y=x+17
y=3x+1
notice how both of the equations equal y. Therefore, we can substitute one expression as y in the other expression. (It'll equal y=y, which is a true statement)
so it'll be:
3x+1=x+17
subtract 1 from both sides
3x=x+16
subtract x from both sides
2x=16
divide by 2
x=8
now, substitute 8 as x into one of the equations and solve for y
let's take the first one for example
y=8+17
y=25
so the answer is x=8, y=25. As a point it's (8,25)
Hope this helps!
