(1,3) means that x = 1 and y = 3. Let's make substitutions to see what happens with the inequality

5*x + y < -3
5*1 + y < -3 ... replace x with 1
5*1 + 3 < -3 ... replace y with 3
5 + 3 < -3
8 < -3

This is false. The number 8 is NOT smaller than -3.

So (1,3) is NOT a solution

Answer: Choice A) No

Construct 3 linear equation starting with qiven solution z = 1/3

Andreyy89

Answer:

(a) $9z+2=5$

(b) $21z-11=-4$

(c) $4z=2-2z$

Step-by-step explanation:

We are required to construct 3 linear equations starting with the given solution z = 1/3.

<u>Equation 1</u>

<u /> $z=\frac{1}{3}$ <u />

Multiply both sides by 9

$9z=\frac{1}{3}\times 9\\9z=3$

Rewrite 3 as 5-2

9z=5-2

Add 2 to both sides

Our first equation is: $9z+2=5$

<u>Equation 2</u>

<u /> $z=\frac{1}{3}$ <u />

Multiply both sides by 21

$21z=\frac{1}{3}\times 21\\21z=7$

Rewrite 7 as 11-4

21z=11-4

Subtract 11 from both sides

Our second equation is: $21z-11=-4$

<u>Equation 3</u>

<u /> $z=\frac{1}{3}$ <u />

Multiply both sides by 6

$6z=\frac{1}{3}\times 6\\6z=2$

Rewrite 6z as 4z+2z

4z+2z=2

Subtract 2z from both sides

Our third equation is: $4z=2-2z$

Answer:

(13,-23)

Step-by-step explanation:

Comparing the image coordinates to the transformation rule, you see that ...

(x -4, y +15) = (9, -8)

Adding (4, -15) to these coordinates, we get ...

(x -4, y +15) +(4, -15) = (9, -8) +(4, -15)

(x-4+4, y+15-15) = (9+4, -8-15)

(x, y) = (13, -23) . . . . coordinates of D

Which function has the greater maximum value: f(x) = -2x2 + 4x+3, or g(x),

Zepler [3.9K]

Answer:

B

Step-by-step explanation:

f(x) maxmum value is

$\frac{ - 4}{ - 4} = 1$

$- 2( {1}^{2} ) + 4(1) + 3 = 5$

G(x) minimum value is 6.

B is the answer.
