So the given angles are supplementary (add to 180). You take the two and add them. 21x+5+37x+1. This gets set to equal 180. 58x+6=180. Subtract 6 from both then divide by 58. You get x=3
Answer:
y=-2x^2-4
Step-by-step explanation:
The parabola is wider than it's parent function, y = x^2. Therefore the coefficient, of x^2 (when you refer to quadratic equations it's a) should be greater than 1. Let's take 2.
y = 2x^2
Now it is reflected across the x-axis, so the equation turns to y = -2x^2. The vertex is shifted down 4. Note that it is shifted down, along the y-axis. This makes 'c' (again quadratic equations) -4.
Final Equation: y=-2x^2-4
Answer:
27
Step-by-step explanation:
127 decrease to 10 is 27
Answer:
y = -2x-7/9
Step-by-step explanation:
Slope-intercept form is y=mx+b where m is the slope and b is the y intercept. Start by solving for y.
-18x-9y=7
-9y=18x+7 (divide through by -9)
y=-2x-7/9
Answer:
8
Step-by-step explanation:
4/6 out of 12 is 8,so There are 8 black birds.
Hope this helps
