BRAINLIEST! PLS HELP! Solve the following system of equations: (5 points)

x − 2y = 5
2x − 4y = 10

Infinitely many solutions
No solutions
(0, 0)
(5, 10)

And please give explanation so I know how to do it. Thank you! :)

A: Infinitely many solutions

Step-by-step explanation:

Use the formula a1/ a2 = b1/ b2 = c1/c2. If all of them equal to each other, then they are an infinitely many solutions.

Here I will apply that:

a1 = 1 or x

a2 = 2

b1 = -2

b2 = -4

c1 = 5

c2 = 10

1/2 = -2/-4 = 5/10

1/2 = 1/2 = 1/2.

All of them give and equal the same answer which is 1/2. Therefore, they are infinitely many solutions.

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
