The equation is y=-2x ^ 2 + 4 x + 30 that’s the equation thru the proabola but if you do point slope form then it is y=18x+54 so it depends what your working on in class

Answer:
B) 40
Step-by-step explanation:
Vertical angle XZU has the same measure as the given angle, 130°. It is equal to the sum of right angle XZV and unknown angle UZV. So, ...
∠UZV +90° = 130°
∠UZV = 40° . . . . . . . . . subtract 90°
2x - 17y = 13
Since we don't have the the value of x we would set x = 0
2(0) - 17y = 13
And solve
-17y = 13
y = -13/17
You would do the same if you're solving for x
2x - 17(0) = 13
2x = 13
x = 13/2
(I'm not sure if you are missing anything but based on the information provided this is how I would solve it.)
Answer:
c. 3.2
Step-by-step explanation:
5(x+2)=7(4-x)
5(x+2)=7(-x+4)
5x+5*2=-7x+7*4
The equation representing the real-world scenario is linear as shown io the graph.
Generally, a linear equation takes the form:
The slope (m) is calculated using the formula:
On the line, we have the points: (0, 1600), (4, 1200)
Substituting we have:
The y-intercept is the value of the y-axis when the line cuts the y-axis
y-intercept : (0, 1600)
Hence, the equation is:
