4 times as much as 3 is

Answer:

A

Step-by-step explanation:

-4u - w = u + 6w

-4u = u + 7w  (Add w to both sides)

-5u = 7w (Subtract u from both sides)

w = [tex]-\frac{5u}{7}[/tex] (Divide both sides by 7)

Answer:

w=(-5u)/7

Step-by-step explanation:

-4u-w=u+6w

Combine like terms

-4u-u=6w+w

-5u=7w

Divide both sides by 7 to cancel it out on the right side and isolate w

(-5u)/7=(7w)/7

(-5u)/7=w

w=(-5u)/7

I hope this helps! If it did, a brainliest would be much appreciated :)

Answer:

Step-by-step explanation:

The sum of two complementary angles is 90.

Let the two angles be x and y.

If x and y are complementary, then x+y = 90

If the larger of two complementary angles is 6 degrees less than 7 times the smaller then y = 7x-6 (y is the larger and x is the smaller)

Substituting y = 7x-6 into the formula above;

x+7x-6 = 90

8x - 6 = 90

8x = 90+6

8x = 96

x = 96/8

x = 12°

Hence the measure of the smaller angle is 12°

Answer:

[tex]x=-11[/tex]

Step-by-step explanation:

So we have the equation:

[tex]5+(x-2)=-8[/tex]

Let's subtract 5 from both sides:

[tex](5+(x-2))-5=(-8)-5[/tex]

The left side will cancel. Subtract on the right:

[tex]x-2=-13[/tex]

Now, add 2 to both sides:

[tex](x-2)+2=(-13)+2[/tex]

Again, the left side will cancel. Add the right:

[tex]x=-11[/tex]

And we're done!

Answer:

it should be x=5

Step-by-step explanation:

5+(x-2)= -8

3+x=8

-3    -3

answer is x=5

Answer:

f^-1(x)=x-3/2

Step-by-step explanation:

we have f(x)=2x+3

let

y=f(x)

y=2x+3

Exchanges the variables x for y and y for x

x=2y+3

isolate the variable y

2y=x-3

y=x-3/2

let

f^-1(x)=y

f^-1(x)=x-3/2

Answer:

Step-by-step explanation:

The answer is B on Edgenuity

f^-1 (x) = 1/2x - 3/2

Answer:

[tex] { \boxed{ \bold{ \huge{ { \boxed{ \sf{ \frac{1}{2} }}}}}}}[/tex]

Step-by-step explanation:

Let the missing fraction be x

[tex] \star \: \: \: \sf{x - \frac{3}{10} = \frac{1}{5}} [/tex]

Solve for x.

L.C.M of 1 and 10 = 10

[tex] \longmapsto{ \sf{ \frac{x \times 10 - 3}{10} = \frac{1}{5} }}[/tex]

[tex] \dashrightarrow{ \sf{ \frac{10x - 3}{10} = \frac{1}{5} }}[/tex]

Do cross multiplication

[tex] \longmapsto {\sf{5(10x - 3) = 10 \times 1}}[/tex]

Distribute 5 through the parentheses

[tex] \longmapsto{ \sf{50x - 15 = 10}}[/tex]

Move 15 to right hand side and change it's sign

[tex] \longmapsto{ \sf{50x = 10 + 15}}[/tex]

Add the numbers: 10 and 15

[tex] \longmapsto{ \sf{50x = 25}}[/tex]

Divide both sides by 50

[tex] \longmapsto{ \sf{ \frac{50x}{50} = \frac{25}{50}}} [/tex]

[tex] \longmapsto{ \purple{ \boxed{ \sf{ x = \frac{1}{2} }}}}[/tex]

The missing fraction is [tex] \sf{ \frac{1}{2} }[/tex]

Hope I helped!

Answer:

8.8387 (round to 8.84)

Step-by-step explanation:

To find the percentage of something, convert the percent into decimal form by moving the decimal two places to the left. In this case, the decimal form of 13% is 0.13

Then, multiply this decimal by the number you need to find the percentage of. In this case, that number is 67.99

The result of .13x67.99 is 8.8387.

Answer:

$8.84

Step-by-step explanation:

1.) Start with the 13%

2.) You have 13.

3.) Move the decimal point 2 places to the left.

4.) Now you have 0.13

5.) Multiply 0.13 and 67.99

6.) This equals $8.84

Answer: B

(2.5, ∞)

Step-by-step explanation:

The solution set of the given logarithm inequality will be (2.5,∞).

The exponent indicates the power to which a base number is raised to produce a given number called a logarithm.

In another word, a logarithm is a different way to denote any number.

As per the given logarithm function,

log₂(2x - 1) > 2

By log property

2x - 1 > 2 x 2

2x > 4 + 1

x > 5/2

x > 2.5 so the solution set will be 2.5 < x < ∞ or (2.5,∞).

Hence "The solution set of the given logarithm inequality will be (2.5,∞)".

I think it's the third choice :)) the one you currently have

Answer:

y = 3/4 or y = -3/5

Step-by-step explanation:

Solve for y:

(8 y - 6) (10 y + 6) = 0

Hint: | Find the roots of each term in the product separately.

Split into two equations:

8 y - 6 = 0 or 10 y + 6 = 0

Hint: | Look at the first equation: Factor the left hand side.

Factor constant terms from the left hand side:

2 (4 y - 3) = 0 or 10 y + 6 = 0

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides by 2:

4 y - 3 = 0 or 10 y + 6 = 0

Hint: | Isolate terms with y to the left hand side.

Add 3 to both sides:

4 y = 3 or 10 y + 6 = 0

Hint: | Solve for y.

Divide both sides by 4:

y = 3/4 or 10 y + 6 = 0

Hint: | Look at the second equation: Factor the left hand side.

Factor constant terms from the left hand side:

y = 3/4 or 2 (5 y + 3) = 0

Hint: | Divide both sides by a constant to simplify the equation.

Divide both sides by 2:

y = 3/4 or 5 y + 3 = 0

Hint: | Isolate terms with y to the left hand side.

Subtract 3 from both sides:

y = 3/4 or 5 y = -3

Hint: | Solve for y.

Divide both sides by 5:

Answer: y = 3/4 or y = -3/5

Answer:

The y-intercept of the line would be (C) 8

Step-by-step explanation:

The slope of the line with the equation y = -3x - 5 is -3. When figuring out a slope perpendicular to another line you would use the negative reciprocal of the slope which would lead to the slope of the line to be 1/3.

We know it passes through the point (-3,7), substituting x and y, we would then get our new equation, [tex](7) = \frac{1}{3}( -3) + b[/tex].

Solve the equation by multiplying -3 with 1/3 and the product would be -1. Add negative one on both sides and you would get 8 = b.

Given :-

A line having a slope of 3/2 passes through (2,-1) .

To Find :-

The equation of the line .

Answer :-

According to the question ,

m = 3/2

Point = (2,-1)

We know Point slope form of the line as ,

y - y¡ = m ( x - x ¡ )

Substitute ,

y - (-1) = 3/2 ( x - 2 )

y + 1 = 3/2x - 3/2*2

y +1 = 3/2x - 3

2( y +1) = 3/2x *2 - 3*2

2y + 2 = 3x - 6

3x -2y -8 = 0

  The train is not moving

Step-by-step explanation:
