Is the ordered pair (1, 2) a solution to this system
of equations?
y=-2x +4
7x - 2y = 3

answer need answer i will giveest, sos !

Yes

Step-by-step explanation:

To determine is an ordered pair is a solution to the system of equations, substitute its coordinates into each of the equations.

An ordered pair is written in the form (x, y), so x=1 and y=2.

y = -2x +4

2 = -2(1) + 4      <=simplify this by multiplying (-2)(1)

2 = -2 + 4        <= add

2 = 2         <= same answers

LS = RS

7x - 2y = 3

7(1) - 2(2) = 3     <=simplify this but multiplying 7(1) and 2(2)

7 - 4 = 3           <= subtract

3 = 3          <= same answers

LS = RS

Since (1, 2) satisfies both of the equations, it is a soltuion to the system of equations.

we have the parent function given by,

1. the function is translated 5 units to the left.

so, we get,   becomes

2. the function is translated 5 units to the right.

so, we get,   becomes

3. the function is translated 5 units upwards.

so, we get,   becomes

4. the function is translated 5 units downwards.

so, we get,   becomes

5. the function is reflected across x-axis.

so, we get,   becomes

6. the function is reflected across y-axis.

so, we get,   becomes .

region b will make the inequalities y < 2x + 1 and y > -x - 2 true ⇒ answer a

step-by-step explanation:

* lets study the graph and the inequality to solve the question

- the inequality y > -x - 2

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = -2 that means the line intersect the y-axis at point (0 , -2)

∵ the sign of the inequality is >

∴ we shad the part over the line

  region a and b

- the inequality y < 2x + 1

∵ the form of the inequality is y > mx + c , m is the slope of the line

  and c is the y-intercept (the line intersect y-axis at point (0 , c)

∴ c = 1 that means the line intersect the y-axis at point (0 , 1)

∵ the sign of the inequality is <

∴ we shad the part under the line

  region b and c

∵ the common region between the two lines is region b

∴ region b will make the inequalities y < 2x + 1 and y > -x - 2 true
