Answer:

Original: -4x - 10y = -7

10y = 4x - 7

5y = 2x - 7

Answer: y = 2/5x - 7

Cosine is a trigonometric function. The value of cos(x+π), when the value of cos(x)=-(√3)/2 is √3/2. The correct option is A.

<h3>What is a cosine?</h3>

Cosine is the trigonometric function equal to the ratio of the side next to an acute angle to the hypotenuse in a right-angled triangle.

Given the value of cos(x)=-(√3)/2, therefore, the value of x can be written as,

cos(x) = -(√3)/2

(x) = cos⁻¹ [-(√3)/2]

x = 5π/6 = 150°

Now, the value of cos(x+π) will be,

cos(x+π)

= cos[(5π/6)+π]

= cos(11π/6)

= √3 / 2

Hence, the value of cos(x+π), when the value of cos(x)=-(√3)/2 is √3/2.

6-8x=7x-10x-24 solve for x
lana66690 [7]

Answer:

x = 6

Step-by-step explanation:

Let's solve your equation step-by-step.

6−8x=7x−10x−24

Step 1: Simplify both sides of the equation.

6−8x=7x−10x−24

6+−8x=7x+−10x+−24

−8x+6=(7x+−10x)+(−24)(Combine Like Terms)

−8x+6=−3x+−24

−8x+6=−3x−24

Step 2: Add 3x to both sides.

−8x+6+3x=−3x−24+3x

−5x+6=−24

Step 3: Subtract 6 from both sides.

−5x+6−6=−24−6

−5x=−30

Step 4: Divide both sides by -5.

−5x/-5 = -30 /-5

x=6

What equation represents an exponential function that passes through the point (2, 80)?
Marina86 [1]

Answer:

f(x) = (4\sqrt{5})^{x}

Step-by-step explanation:

The exponential function looks like the following: f(x) = b^{x}.

If the function passes through the point (2, 80), then:

f(x) = b^{x} → 80 = b^{2}

Solving for 'b':

b = \sqrt{80} →b=4\sqrt{5}

Then, the equation of exponential function that passes through the point (2, 80) is: f(x) = (4\sqrt{5})^{x}

3.Maggie drives three times the number of
RUDIKE [14]

Answer:

Step-by-step explanation:

Let the number of hours driven by Maggie be x and that of Alan be y

If Maggie and Alan drive for a total of 32 hours, then;

x+y = 32 ..... 1

Also if Maggie drives three times the number of  hours that Alan drives on their vacation, then x = 3y ...... 2

Substitute eqn 2 into 1;

x+y = 32

3y+y = 32

4y = 32

y = 32/4

y = 8 hours

Since x = 3x

x = 3(8)

x = 24 hours

Hence Maggie drives for 24 hours and Alan drives for 8 hours
