Answer:

A and C

Step-by-step explanation:

A

when x = 2 , that is x > 1 then f(x) = x² , that is

f(2) = 2² = 4 ← True

B

when x = 5, that is x > 1 then f(x) = x² , that is

f(5) = 5² = 25 ≠ 1 ← not true

C

when x = 1 then f(x) = 5 , that is

f(1) = 5 ← True

D

when x = - 2 , that is x < 1 , then f(x) = 2x , that is

f(- 2) = 2(- 2) = - 4 ≠ 4 ← not true

Answer:

y = 14/3 and 2

x = -13/3 and 1

(-13/3, 14/3) and (1, 2)

Step-by-step explanation:

[tex]x + 2y = 5 - - - (a) \\ {x}^{2} - {y}^{2} = - 3 - - - (b)[/tex]

for equation (a)

make x the subject of the formular:

[tex]x = 5 - 2y - - - (c)[/tex]

for equation (b)

[tex] {x}^{2} - {y}^{2} = - 3[/tex]

substitute for x as 5 - 2y in equation (b):

[tex] {(5 - 2y)}^{2} - {y}^{2} = - 3 \\ (25 - 20y + 4 {y}^{2} ) - {y}^{2} = - 3 \\ 25 - 20y + 3 {y}^{2} = - 3 \\ {3y}^{2} - 20y + 28 = 0 \\ (3y - 14)(y - 2) = 0[/tex]

therefore,

[tex]y = \frac{14}{3} \: \: and \: \: 2[/tex]

substitute for all values of y in equation (c):

for y = 14/3:

[tex]x = 5 - 2( \frac{14}{3} ) \\ \\ x = 5 - \frac{28}{3} \\ \\ x = - \frac{13}{3} [/tex]

for y = 2:

[tex]x = 5 - 2(2) \\ x = 5 - 4 \\ x = 1[/tex]

Answer:

(1, 2)

(-13/3, 14/3).

Step-by-step explanation:

x + 2y = 5

x² - y² = -3​

From the first equation x = 5 - 2y

Substitute for y in the second equation:

(5 - 2y)^2 - y^2 = -3

25 + 4y^2 - 20y - y^2 = -3

3y^2 - 20y + 28 = 0

Factoring:-

(3y - 14(y  -  2)   = 0

y = 2, 14/3.

So when y = 2, x = 5 - 2(2) = 1.

When y = 14/3, x = 5 - 2(14/3) = -13/3.

Checking the results in the second equation:

(1, 2):-

1^2 - 2^2 = -3    Correct.

(-13/3, 14/3):-

(-13/3)^2 - (14/3)^2 = -3   Correct.

Answer:

answer is the pic down below

Step-by-step explanation:

Answer:

TU = 29

Step-by-step explanation:

TU + UV = TV , substitute values

9x + 2 + 5 = 14x - 8 , that is

9x + 7 = 14x - 8 ( subtract 14x from both sides )

- 5x + 7 = - 8 ( subtract 7 from both sides )

- 5x = - 15 ( divide both sides by - 5 )

x = 3

Then

TU = 9x + 2 = 9(3) + 2 = 27 + 2 = 29

Answer:

A

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c

Given

3x - y = 4 ( subtract 3x from both sides )

- y = - 3x + 4 ( multiply through by - 1 )

y = 3x - 4 → A

The component form of the vector that translates will be 11i - 17j.

A spatial transformation is each mapping of feature space to itself and it maintains some spatial correlation between figures.

The translation does not change the shape and size of the geometry. But changes the location.

The point A(-4, 8) is translated to the point A'(7, -9). Then the rule of the transformation is given as,

(7, - 9) = (- 4 + x, 8 + y)

Compare the abscissa, then we have

7 = - 4 + x

x = 7 + 4

x = 11

Compare the ordinate, then we have

y + 8 = - 9

y = - 8 - 9
y = - 17

The component form of the vector that translates will be 11i - 17j.

More about the transformation of a point link is given below.

Step-by-step explanation:

2x+2y=....

So you substitute x for 4 and y for -3.

Which would will give you 2(4)+2(-3). 2·4+2·3 which would give you 8+-6

Then you would add 8 and -6.

8+-6

That should give you 2.

Answer: Square root of negative 7 is greater than -3.12345

Step-by-step explanation: Since the square root of -7= 2.64575131 i (A positive number) Then it's greater, since the positive number is always greater than the negative numbers, because the negative numbers are further below zero than the positive number, if there is a number below the zero and a number above the zero, the one above the zero is greater,  because it's a positive number, the one below 0 is negative.
