Find the greatest odd integer value of x that satisfies the inequality -3x > -105.​

Answer:

The image if the point is (-7, -9)

Step-by-step explanation:

∵ The given point is (9, -7)

∴ x = 9 and y = -7

∵ The given point is rotated 270° counterclockwise about the origin

→ By using the third rule above

∴ The image of the point is (y, -x)

→ That mean change the sign of x-coordinate, then switch them

∵ x = 9 and y = -7

∴ The image if the point is (-7, -9)

Answer:

B. [tex]y= \left \{ {{x^{2}+4,\,x< 2 } \atop {-x+4,\,x \ge 2}} \right.[/tex]

Step-by-step explanation:

The piecewise function consists in two functions:

(i) A vertical parabola directed in the +x direction and centered at [tex]V(x,y) = (0, 4)[/tex] for all [tex]x \in (-\infty, 2)[/tex]. That is:

[tex]y = x^{2}+4[/tex], [tex]x < 2[/tex]

(ii) A line with negative slope for all [tex]x \in [2, +\infty)[/tex].

[tex]y = -x+4[/tex], [tex]x \ge 2[/tex]

The correct answer is B.

Answer:

The length of the first piece is 0.51 m

The length of the second piece is 0.31 m

The length of the third piece is 0.28 m

Step-by-step explanation:

The question is a simultaneous equation with word problem

The total length of the wood = 0.9 m

The number of pieces the wood is cut into = 3

The length of the first piece = 0.2 m + The length of the second piece

The length of the third piece = The length of the second piece - 0.23 m

Let "y" represent the length of the second piece, let "x" represent the length of the first piece, and let "z" represent the length of the third piece, we have;

x = 0.2 + y...(1)

z = y - 0.23...(2)

x + y + z = 0.9...(3)

Therefore, by substitution, we have;

0.2 + y + y + y - 0.23 = 0.9

3·y - 0.03 = 0.9

3·y = 0.9 + 0.03 = 0.93

y = 0.93/3 = 0.31

y = 0.31

The length of the second piece = y = 0.31 m

From equation (1), we have;

x = 0.2 + y = 0.2 + 0.31 = 0.51

x = 0.51

The length of the first piece = x = 0.51 m

From equation (2), we have;

z = y - 0.23

z = 0.51 - 0.23 = 0.28

z = 0.28

The length of the third piece = z = 0.28 m.

Answer:

Choice 2 and 4 should be the answer

Step-by-step explanation:

For choice 2: both started away from home and finished at home.

For choice 4, Peter is farther away from home than Camilla, but they reached home at the same time which proves that Peter is faster.

Answer:

[tex]y=1/3x[/tex]

Step-by-step explanation:

It's positive, and it goes up once for every three times it goes to the right.

Domain is basically an input while Range is an output. Domain is the set of all x-values while Range is the set of y-values.

[tex]\large \boxed {domain} = > \large \boxed{range}[/tex]

From input to output. That means from if we substitute domain in the equation, we would get range.

[tex]f(x) = 4x + 2 \\ f(0) = 4(0) + 2 = 0 + 2 = 2 \\ f(3) = 4(3) + 2 = 12 + 2 = 14 \\ f(6) = 4(6) + 2 = 24 + 2 = 26[/tex]

We input the value of x that are given and we get the value of f(x) which is the output at the specified domain.

[tex] \large \boxed{2, 14, 26}[/tex]

Answer:

The smallest angle is the angle shown by 3x - 17 which ends up being 49°.

Step-by-step explanation:

The angles of a triangle add up to 180 degrees. We can write an equation and solve for x.

75 + (2x + 12) + (3x - 17) = 180

~Combine like terms

70 + 5x = 180

~Subtract 70 to both sides

5x = 110

~Divide 5 to both sides

x = 22

Using what we found for x, solve for the missing angles.

2x + 12

2(22) + 12

44 + 12

66

3x - 17

3(22) - 17

66 - 17

49

Answer:

65-n

Step-by-step explanation:

"less than" means you will subtract the second number by the first, therefore 65 less than a number is 65-n.

Answer:

x-intercept: -1/7

y-intercept: 1/4

Step-by-step explanation:

change equation into standard form:  7x - 4y = -1

set 'x' to zero and solve for y:  0 - 4y = -1

                                                        y = 1/4

set 'y' to zero and solve for x:  7x - 0 = -1

                                                        x = -1/7

Answer:

x = -0.22   or x = -2.28

Step-by-step explanation:

2x^2 + 5x + 1 = 0

You use the quadratic formula: -b ±√5² - 4 x 2 x 1 ÷ (2 x 2)

-5 +√17 ÷ 4 = -0.22

-5 - √17 ÷ 4 = -2.28

Answer:

mark of the fifth exam = 60

Step-by-step explanation:

Mean = sum of all marks / number of exam

Mean = 70

Number of exam = 5

Let x =

Mean = sum of all marks / number of exam

70 = (65 + 80 + 76 + 69 + x) / 5

Cross product

70 × 5 = (290 + x)

350 = 290 + x

350 - 290 = x

x = 60

mark of the fifth exam = 60

Answer:

Step-by-step explanation:

b/c this is an isosceles triangle  we know that either leg is the same length.. so we can use many trig functions  :)

SOH CAH TOA to remember how trig functions fit on the triangle...

we know the hypotenuse and the angle and we want to find the adjacent leg ( which for this triangle is also the opposite leg )

use Cos = Adj / Hyp

Hyp*Cos(45) = adj

16* [tex]\sqrt{2}/2[/tex] = adj

8*[tex]\sqrt{2}[/tex] = adj

each leg is the same  [tex]8\sqrt{2}[/tex]
