Answer: Hi!

First, we should combine like terms:

4b + 5b = 8b − 1 +3b + 15 =

9b = 11b + 14

Now, we should subtract 11b from both sides.

-2b = 14

Now, we should divide both sides by -2.

b = -7

Hope this helps!

Answer:

$\Huge \boxed{b=-7}$

Step-by-step explanation:

$4b+5b=8b-1+3b+15$

Combining like terms.

$9b=11b+14$

Subtracting 9b and 14 from both sides.

$-14=11b-9b$

$-14=2b$

Dividing both sides by 2.

$-7=b$

The point (-7, -24) is on the terminal ray of angle θ which is in standard position. A student found the six trigonometric value

Delicious77 [7]

Answer:

The $\sin \theta, \tan \theta, \csc \theta, \cot \theta$ have the wrong values.

Step-by-step explanation:

The point (-7,-24) lies in the third quadrant, where the only tangent function will have a positive value and all the other trigonometric functions are negative.

The origin has a distance from the point is $\sqrt{(- 7)^{2} + (- 24)^{2}} = 25$ .

If the point makes an angle $\theta$ with the negative x-axis, then

$\sin \theta = - \frac{24}{25}$

$\cos \theta = -\frac{7}{25}$

$\tan \theta = \frac{24}{7}$

$\sec \theta = - \frac{25}{7}$

$\csc \theta = - \frac{25}{24}$

$\cot \theta = \frac{7}{24}$

Therefore, the $\sin \theta, \tan \theta, \csc \theta, \cot \theta$ have the wrong values. (Answer)

natulia [17]

Step-by-step explanation:

0.40 ___0.04

We are given with two decimal numbers. Compare the numbers and complete the blank by < or > or =

To compare the decimals , compare each digit from left to right

0 is equal to 0

4 is greater than 0

so we can say 0.40 is greater than 0.04

0.40 > 0.04

Both decimal numbers are not equal

Answer:

0.40 > 0.04

At a supermarket, the price of a Thanksgiving turkey is determined by how many pounds the turkey weighs. The price of a 12.4 pou

Lelu [443]

Answer:

The expression is: $p = 1.25*t$

Step-by-step explanation:

Since the price is determined by the weight of the turkey, we need to find the value of one pound in order to create the expression, to do that we will apply the point given.

$\text{price per pound} = \frac{\text{price}}{\text{weight}}\\\text{price per pound} = \frac{15.5}{12.4} = 1.25$

Each pound costs $1.25, therefore the expression used to calculate the price of the turkey must be the weight of the turkey in pounds multiplied by the price of each pound.:

$p = 1.25*t$

1. x = 20 , x² = 400 and x³ = 8000

2. x = 7 , x² = 49 and x³ = 343

Step-by-step explanation:

Given values are;

2000, 7, 400, 20, 4000, 200

We have to find x, x² and x³.

Part 1:

$x^3=8000$

We will take cube root to find x.

$\sqrt[3]{x^3} =\sqrt[3]{8000}$

$x=20$

Now, we will take square;

$(x)^2=(20)^2\\x^2=400$

Therefore;

x = 20 , x² = 400 and x³ = 8000

Part 2:

x² = 49 , x³ = 343

Taking square root on x²

$\sqrt{x^2}=\sqrt{49}\\x=7$

Therefore;

x = 7 , x² = 49 and x³ = 343
