Answer:
A -7 - (4)
Step-by-step explanation:
Answer:
y = 7
Step-by-step explanation:
The straight line which is perpendicular to the y-axis will be either x-axis or parallel to the x-axis.
Now, the general equation for all straight line which is either x-axis or parallel to x-axis are given by y = c ........... (1), where c is any constant.
For c = 0 the line will be x -axis. therefore, y = 0, is the equation of x-axis.
Now, if the line (1) passes through the point (-2, 7), then the equation will be y = 7. (Answer)
{Since, the point (-2,7) will satisfy the equation (1) and then c will be equal to 7.}

Answer:
f(3) = -13
Step-by-step explanation:
To answer this question, we plug 3 into the place of x, so the equation now looks like;
f(3) = -5(3) + 2
We simply apply PEMDAS by multiplying -5 and 3, then adding 2 to get;
f(3) = -13
Hope this helps!

Answer:
(c) (4, 3)
Step-by-step explanation:
The next step in the solution of System B is to divide by 15 1/2. This will result in the equation ...
x = 4
The only answer choice that has x = 4 is the ordered pair (4, 3). That ordered pair is the solution to the system.
__
(15 1/2)x = 62 ⇒ (31/2)x = 124/2 ⇒ x = (124/2)/(31/2) = 124/31 = 4
