15(25-5a)=4-a
375-75a=4-a
Add 75a to both sides
375= 4+74a
Subtract 4 from both sides
371=74a
Divide both by 74
5.01=a

Answer:

The value of the equation for a is 371/74 or 5.0135.  

Step-by-step explanation:

Consider the provided equation.

15(25-5a)=4-a

We need to solve the provided equation for a.

Open the parentheses.

375-75a=4-a

Add a to both side.

375-75a+a=4-a+a

375-74a=4

Subtract 375 from both the sides.

375-375-74a=4-375

-74a=-371

Divide both the sides by -74.

a=\frac{371}{74}

Hence, the value of the equation for a is 371/74 or 5.0135.

Which should equal 105 to prove that f // g ? <br><br> A<br> B<br> C<br> D <br> Please hurry !!
frosja888 [35]

since you have the 75, we know that a would equal 105 for line g , since a line = 180 degrees

 so to make line f parallel with g it needs the same angles with line n as line g has

so if a = 105, then angle d would also need to be 105

 The answer is D

Write an equation of the form y=a sin bx or y= a cos bx to describe the graph below.
kakasveta [241]

we conclude that the graphed equation is:

y = 4*cos(pi*x)

<h3></h3><h3>Which trigonometric equation is the one in the graph?</h3>

First, we can see that the graphed function is even, so we know that it wiill be a cosine.

We also can see that the maximum is 4 and the minimum is -4, so the amplitude is 4.

Then we have something like:

y = 4*cos(b*x)

To find the value of b, we can use the fact that the zeros of the function are at x = ±1/2

Then:

b*1/2 = pi/2

b = pi

Finally, we conclude that the graphed equation is:

y = 4*cos(pi*x)

omeli [17]

Answer:

y =  \frac{1}{8} x - 3

Step-by-step explanation:

Formula for straight lines:

y = mx + b

where m = slope, b = constant

Given:

y-intercept = -3 (0, -3)

m = ⅛

Substitute into formula to find b.

- 3 =  \frac{1}{8} (0) + b \\  - 3 = 0 + b \\ b =  - 3

Substitute b into original formula

y = mx + b \\ y =  \frac{1}{8} x + ( - 3) \\ y =  \frac{1}{8} x - 3
