solve the system of linear equations by substitution. x+4y=18 y=-x+9

Answers

Using the substitution method, the solution to the system of linear equations, is: (6, 3).

System of Linear Equations

Using substitution method, we can make one of the variables the subject of the formula for one of the equations, then find the other variable by substituting.

Given:

x + 4y = 18 --> eqn. 1y = -x+9 --> eqn. 2.

Substitute y = -x + 9 into equation 1.

x + 4(-x + 9) = 18

x - 4x + 36 = 18

-3x + 36 = 18

-3x = 18 - 36

-3x = -18

x = 6

Substitute x = 6 into equation 2 to find y

y = -6 + 9

y = 3

Therefore, using the substitution method, the solution to the system of linear equations, is: (6, 3).

Please help me with this

Answers

Answer:

  see attached

Step-by-step explanation:

The grid show the non-possibilities in red, with each number corresponding to the statement that eliminates that choice. The green square (with black text) shows the one combination that is specified already (by statement 4). The lighter green numbers show possible alternatives: first period may be Schiller or English, and room 113 will be the other one. Similarly, Art may be 3rd period or Thomlinson.

__

These choices (light green 5, light green 6) give rise to four possibilities. Working through them, you run into inconsistencies if you choose Schiller for first period. (Art must be, but can't be, in room 112.) That leaves two possibilities.

Again, you run into inconsistencies if you choose Thomlinson as the Art teacher. (The class in 112 is 2 periods after Xavier's class, not 1.)

Hence, the only viable pair of remaining choices is Schiller in room 113 and art in 3rd period.

The final schedule is shown in the attachment.

_____

Additional comment

When I'm working these on paper, I use an X to mark any impossible combinations, and a circle (O) to mark a known combination. In any given 4×4 square of the grid, the remaining cells of the row and column containing a O must be Xs. Consistency must be maintained between rows and columns. This often means filling a circle in one place may result in a circle being filled in another place. Of course, once 3 of the squares in a row or column have Xs, the remaining one must be O.

How do you determine the value of the unknown exponent in the
equation 9,700 divided by 10 to the power of what equals 0.97?

Answers

Answer:

?=4

Step-by-step explanation:

First, we have to tell how we got from 9700 to 0.97. so we know that it is divided by 10^?. When you divide by 10, it is the same as moving the decimal point one space to the left. SO all you have to do is count how many times the decimal point got moved to get from 9700 to 0.97. This number is 4 so the question mark is 4 because 9700/10^4 will move the decimal place 4 to the right and give you 0.97.

The English expression is ambiguous in that we cannot tell if the number is decreased by 10 before becoming part of the product (9(n-10)), or if the correct interpretation is the one shown above. The order of operations is used as a guide, telling us that the multiplication is done before the subtraction since there is no indication of grouping.

For x-intercepts, y is zero y = x² - 12x + 32 then x-intercept is (8,0) and (4,0)

For x-intercepts, y is zero y = x² - 10x + 24 then x-intercept is (6,0) and (4,0)

For x-intercepts, y is zero y = x² + 10x + 16 then x-intercept is (-2,0) and (-8,0)

For x-intercepts, y is zero y = x² - 25 then x-intercept is (5,0) and (-5,0)

For x-intercepts, y is zero y = x² + 8x + 12 then x-intercept is (-2,0) and (2,0)

What is x-intercepts?

X- intercepts is "x coordinates of a point where a line, a curve or surface intersects at x- axis".

According to the question,

a) y = x² - 12x + 32 (Put y=0)

x² - 12x + 32 = 0

(x-8) (x-4) = 0

x - 8 =0: x - 4 = 0

x = 8 and 4

x - intercept is (8,0) and (4,0)

b) y = x² - 10x + 24 (Put y=0)

x² - 10x + 24= 0

(x-6) (x-4) = 0

x - 6 = 0: x - 4 = 0

x = 6 and 4

x - intercept is (6,0) and (4,0)

c) y = x² + 10x + 16 (Put y=0)

x² + 10x + 16 = 0

(x+2) (x+8) = 0

x + 2=0: x + 8 = 0

x = -2 and -8

x - intercept is (-2,0) and (-8,0)

d) y = x² - 25 (Put y=0)

x² - 25 = 0

x² = 25

x = ± 5

x - intercept is (+5,0) and (-5,0)

e) y = x² + 8x + 12 (Put y=0)

x² + 8x + 12 = 0

(x+2) (x+6) = 0

x + 2=0: x + 6 = 0

x = 2,6

x - intercept is (2,0) and (6,0)
