Solve the inequality and enter your solution as an inequality comparing variable to solution-31>x-48

Answers

Answer:

solving the inequality [tex]-31>x-48[/tex] we get: [tex]\mathbf{x<17}[/tex]

Step-by-step explanation:

We need to solve the inequality [tex]-31>x-48[/tex]

Solving the inequality and finding value of x:

[tex]-31>x-48[/tex]

First we will be switching sides i.e. left hand side will become right hand side and right hand side will become left hand side. In doing so, the inequality sign i.e. > will be reversed and changed with <

[tex]x-48<-31[/tex]

Now, for finding value of x, we will be adding 48 on both sides

[tex]x-48+48<-31+48\\x<17[/tex]

The value of x is less than 17 i.e. [tex]\mathbf{x<17}[/tex]

So, solving the inequality [tex]-31>x-48[/tex] we get: [tex]\mathbf{x<17}[/tex]

[tex]\huge\boxed{\tt{x = -5 , y = 2}}[/tex]

Step-by-step explanation:

x = y - 7 ---------------------(1)

-y - 2x = 8 --------------------(2)

Put Equation (1) into (2)

- y - 2 ( y-7 ) = 8

-y - 2y + 14 = 8

-3y = 8 - 14

-3y = -6

Divide -3 to both sides

y = -6 / -3

y = 2

Put y = 2 in (1)

x = 2 - 7

x = -5

So,

x = -5 , y = 2

Answers

Answer:

C (0.9)

Step-by-step explanation:

Key skills needed: Solving one variable equations

1) we have the equation --> 12.72 = 5.52 + 8x

2) We need to solve for x.

To get x by itself, we subtract 5.52 from both sides. (12.72 - 5.52 = 7.2)

This means 8x = 7.2

3) Divide by 8 from both sides, and you will get x = 0.9 (7.2/8 = 0.9)

The vertex of a quadratic function is (6, 2), and the y-intercept of the function is (0, −70). The equation of the function in vertex form, f(x)=a(x−h)2+k, is shown.−70=a(0−6) squared+2

Answers

Answer:

The equation of the function in vertex form is represented by [tex]y = -2\cdot (x-6)^{2}+2[/tex].

Step-by-step explanation:

Let [tex](h,k) = (6,2)[/tex] and [tex](x,y) = (0, - 70)[/tex], now we substitute on the equation of the quadratic function and solve for [tex]a[/tex]:

[tex]y = a\cdot (x-h)^{2}+k[/tex]

[tex]-70 = a\cdot (0-6)^{2}+2[/tex]

[tex]-70 = 36\cdot a + 2[/tex]

[tex]36\cdot a = -72[/tex]

[tex]a = -2[/tex]

Therefore, the equation of the function in vertex form is represented by [tex]y = -2\cdot (x-6)^{2}+2[/tex].

The length of which line segment is equal to the exact value of the sine if theta?

Option 3: line segment OR
Option 4: line segment OS

Answers

Answer: Option 2. Segment TS

====================================================

Explanation:

Recall that the sine of an angle is equal to the ratio of opposite over hypotenuse.

In other words,

sin(angle) = opposite/hypotenuse

With respect to reference angle theta, the side TS is opposite this angle. It is the leg furthest from the angle. The hypotenuse is the longest side segment TO. The hypotenuse is always opposite the 90 degree angle.

For a unit circle, the radius is 1, so segment TO is 1 unit long.

Therefore,

sin(angle) = opposite/hypotenuse

sin(theta) = TS/TO

sin(theta) = TS/1

sin(theta) = TS

Answer:

B. 40, 51.5, 88.5

Step-by-step explanation:

(5x - 4) + (2x + 3) + (3x- 4) = 180

10x - 5 = 180

10x = 185

x= 18.5

Substitute

5(18.5) - 4 = 88.5

2(18.5) + 3 = 40

3(18.5) - 4 = 51.5
