Answer:
42.5
Step-by-step explanation:
It equals 90 degrees because it's a right angle, so:
3 + 2 = 5
90 - 5 = 85
Since there is space at the top, you need to have the correct amount for both sides. So:
85 ÷ 2 = 42.5
Here is how you solve for y:
The answer to your query is
y = -3/2x + 4. Hope this helps!
1) m-5= -18 (add 5 to both sides)
m= -13
2) m-11= -4 (add 11 to both sides)
m= 7
3) x+10=22 (subtract 10 from both sides)
x= 12
4) n-19= -16 (add 19 to both sides)
n= 3
Answer:
Step-by-step explanation:
Answer:
y = - 2x - 4
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y-intercept )
To calculate m use the gradient formula
m = ( y₂ - y₁ ) / ( x₂ - x₁ )
with (x₁, y₁ ) = (- 2, 0) and (x₂, y₂ ) = (0, - 4) ← 2 points on the line
m = = = - 2
not the line crosses the y-axis at (0, - 4) ⇒ c = - 4
y = - 2x - 4 ← equation of line
