Answer:
B
Step-by-step explanation:
4x + 2y = 3
(send 2y to the right and 3 to the left)
4x - 3 = -2y
(divide everything by -2)
(4x)/(-2) - 3/(-2) = y
So now we have a function which is like
y = ax + c
c = the y value of intersection point of the equation and the y-axis
a = amount of increase in y values per x value
so in this example:
(4x/(-2)) = (4/(-2))x -> a = 4/(-2) = -2
and
c = -3/-2 = 3/2
So the graph that we're searching for is increasing (-2) y values (so decreasing 2 y values) per 1 x value and has an intersection with the y-axis where y = 3/2
Answer:
<h2>(x + 7)² + (y + 2)² = 49</h2>
Step-by-step explanation:
The standard form of an equation of a circle:
(h, k) - center
r - radius
We have:
center (-7, -2) → h = -7 and k = -2
radius r = 7.

Step-by-step explanation:</h3>
The solid dot on the right-hand portion of the curve means the function is defined for x ≥ 2. Choices A and C have that condition.
The function is linear for x ≥ 2, so matches selection C, not A.
There are 3 questions and 4 choices.
So she has 1/4 of a chance of getting each question right.
Now if you multiply all her odds 1/4 x 1/4 it would become 1/16. Therefore she has 1/16 of a chance of getting a 2/3
