Answer:

x< -17/6

Step-by-step explanation:

This is actually quite easy

all you have to do is divide -6 from both sides to isolate X

-6x/-6 > 17/ -6 (but here is the thing, when it is an inequality and you are dividing by a negative number, you flip the sign, so ">" turns to "<."

so, the answer is x< -17/6 (you cannot simply it!)

Answer:

The slope is -2

Step-by-step explanation:

(0,4) (3,-2)

remeber the equation is Y2-Y1/X2-X1

Y2 = -2

Y1 = 4

X2=3

X1=0

Plug it in the euqation to see if it works

The law of cosines is used to find the measure of Z.

Shtirlitz [24]

Answer:

C. $Z=51^{\circ}$

Step-by-step explanation:

We have been given a triangle. We are asked to find the measure of angle Z using Law of cosines.

Law of cosines: $c^2=a^2+b^2-2ab\cdot \text{cos}(C)$ , where, a, b and c are sides opposite to angles A, B and C respectively.

Upon substituting our given values in law of cosines, we will get:

$16^2=19^2+18^2-2(19)(18)\cdot \text{cos}(Z)$

$256=361+324-684\cdot \text{cos}(Z)$

$256=685-684\cdot \text{cos}(Z)$

$256-685=685-685-684\cdot \text{cos}(Z)$

$-429=-684\cdot \text{cos}(Z)$

$\frac{-429}{-684}=\frac{-684\cdot \text{cos}(Z)}{-684}$

$0.627192982456=\text{cos}(Z)$

$\text{cos}(Z)=0.627192982456$

Now, we will use inverse cosine or arc-cos to solve for angle Z as:

$Z=\text{cos}^{-1}(0.627192982456)$

$Z=51.1566718^{\circ}$

$Z\approx 51^{\circ}$

Therefore, the measure of angle Z is approximately 51 degrees.

7n2 + 5 = 453<br> Solve the quadratic function

Reptile [31]

7n^2 + 5 = 453

Subtract 5 from both sides:

7n^2 = 448

Divide both sides by 7:

N^2 = 64

Take the square root of both sides:

N = 8

The car you want cost 25,750. If the sales tax rate is 6.5% the how much sales tax will be added? What is the total cost for the

lilavasa [31]

Answer:The total cost for the car including tax is $27423.75

Step-by-step explanation:

The initial price of the car that you want is 25,750. If the sales tax rate is 6.5%, it means that the amount of sales tax would be

6.5/100 × 25750 = 0.065 × 25750 = 1673.75

The total cost for the car including tax would be the sum of the initial cost of the car and the amount of tax. It becomes

25750 + 1673.75 = $27423.75
