PLEASE HELP ME WITH THIS I WILL MARK BRAINLIEST!! Classify each system of equations as having a single solution, no solution, or

Wewaii [24]

Answer:

see the explanation

see the attached figure

Step-by-step explanation:

Part 1) we have

$y=11-2x$ ----> equation A

$4x-y=7$

Isolate the variable y

$y=4x-7$ ----> equation B

Compare the slope of both lines

The slopes are different

That means

The lines intersect at one point

therefore

The system has one solution

Part 2) we have

$x=12-3y$

isolate the variable y

$y=-(1/3)x+4$ -----> equation A

$3x+9y=24$

isolate the variable y

$y=-(1/3)x+(8/3)$ ----> equation B

Compare equation A and equation B

The slopes are equal

The y-intercept are different

That means

we have parallel lines with different y-intercept

The lines don't intersect

therefore

The system has no solution

Part 3) we have

$2x+y=7$

isolate the variable y

$y=-2x+7$ -----> equation A

$-6x=3y-21$

isolate the variable y

$y=-2x+7$ ----> equation B

Compare equation A and equation B

The equations are identical

That means

Is the same line

The system has infinitely solutions

Part 4) we have

$x+y=15$

isolate the variable y

$y=-x+15$ -----> equation A

$2x-y=15$

isolate the variable y

$y=2x-15$ ----> equation B

Compare the slope of both lines

The slopes are different

That means

The lines intersect at one point

therefore

The system has one solution

Part 5) we have

$2x+y=7$

isolate the variable y

$y=-2x+7$ -----> equation A

$-4x=2y+14$

isolate the variable y

$y=2x-7$ ----> equation B

Compare the slope of both lines

The slopes are different

That means

The lines intersect at one point

therefore

The system has one solution

Part 6) we have

$x+4y=6$

isolate the variable y

$y=-0.25x+1.5$ -----> equation A

$2x=12-8y$

isolate the variable y

$y=-0.25x-1.5$ ----> equation B

Compare equation A and equation B

The slopes are equal

The y-intercept are different

That means

we have parallel lines with different y-intercept

The lines don't intersect

therefore

The system has no solution

A (-3,-2), B(12,3);3 to 2

Archy [21]

O evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.

Write the first five terms of the arithmetic sequence whose first term is 7, and whose common difference is 3.

melisa1 [442]

An arithmetic sequence is one where each term is the sum of the previous number and some constant. we are given the first term is 7 and the common difference is 3. this means our sequence is
7, 10, 13, 16, 19, 21 etc.
