graph the solution to this inequality on the number line. -4x+7>x-13

Answer:

4:13

Step-by-step explanation:

Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).

8 : 26

divide each number by 2

4 : 13

Answer:

81.3 feet

Step-by-step explanation:

A shark is swimming 28 feet below sea level. If the angle of depression from a boat on the water is 19 degrees What is the distance between the boat and the shark?

We solve the above question using Trigonometric function of Tangent

tan θ = Opposite/Adjacent

θ = Angle of depression = 19°

Distance between the boat and the shark = Adjacent = ? = x

Opposite = 28 feet

Hence:

tan 19 = 28/x

Cross Multiply

tan 19 × x = 28

x = 28/tan 19

x = 81.317904575 feet

Approximately = 81.3 feet

The distance between the boat and the shark is 81.3 feet

Answer:

2

Step-by-step explanation:

when x is 2 y = 0.

lets start with writing the function's equation;

it has a slope of 2 so 2x + k = y

given in the question when x = -3, y = -10

so k = -4

y = 2x - 4, 0 = 2x-4 then x = 2

Answer:

Step-by-step explanation:

x-2

Answer:

y = 9/120 or y = 0.24

Step-by-step explanation:

[tex]y=-\frac{2}{5} x+\frac{3}{8}\\\\y=-\frac{2}{5}(\frac{1}{3})+\frac{3}{8} \\\\y=-\frac{2}{15} +\frac{3}{8} \\\\y= \frac{29}{120}[/tex]

Answer:

d1 = 192

d2 = 192

Step-by-step explanation:

step 1

From the imformation given, the distance is the same

so from the table

d1 = 64t

d2 = 48(7-t)

the distance is the same, it means

d1 = d2

therefore we can get the time(t) from here

64t = 48(7-t)

64t = 336 - 48t

collect like terms

64t+48t = 336

112t = 336

t = 336/112

t = 3

substitute t into d1 to get the distance

d1 = 64t

d1 = 64 × 3

d1 = 192

Note, d1 = d2

d2 = 192 too

Step-by-step explanation:

yes it possible to find the length of tu

Answer:

Step-by-step explanation:

Answer:

B

Step-by-step explanation:

Line H is represented by the equation:

[tex]2x+2y=8[/tex]

And we want to find Line K such that the set of equations has infinitely many solutions.

Remember the three solution sets for linear equations:

From Line H, we can divide both sides by two. This yields the equivalent equation:

[tex]x+y=4[/tex]

Therefore, the new equation and Line H are the same line. Thus, they will have infinitely many solutions.

The answer is B.

Answer:

Change in price = 0.154

Step-by-step explanation:

Given that,

The price on Monday = 24.85

The price on Friday = 25.004

We need to find the change in price from Monday to Friday. It can be calculated as follows :

Change = 25.004 - 24.85

= 0.154

So, the required change in the price is equal to 0.154 .

Answer:

The sum will be whichever number has the greater value.

Step-by-step explanation:

Let's say you have (-2) + 4 = ?

The number with the greater value is 4.

So the sum of your answer would be a positive, since the greater number has a positive sign.

Answer:

a) x and 2x are complementary angles.

b) x = 30

Step-by-step explanation:

x + 2x = 90 (Complementary angles)

3x = 90

x = 30

Answer

4 6/12 or 2 3/4 cups of total ingredients

Step-by-step explanation:

There are 2 1/2 cups of butter, 1/3 cups of brown sugar, and 1/2 cups of baking powder.

You'd want to make the denominators the same numbers so it would be easier to divide.

So I multiplied 2 1/2 times 3, 1/3 times 2, and 1/2 times 3.

Then all the numbers would have a denominator of 6. Don't multiply the whole numbers or the numerators. Just the denominator.

''THE NUMBERS'' would change to 2 1/6, 1/6, and 1/6.

If I were to add that it would be 2 3/6.

BUT, You need to multiply by 2 after because it says in the question "How many ingredients in cups will Daniel make the cake twice as large".

What is 2 3/6 times 2 =  4 6/12 total.

If it says to simplify the answer. It would be "'2 3/4 total'' or both answers are correct

Answer:

The inverse of this expression is the multiplication of 4. Answer: 4r, or 4 times r

Step-by-step explanation:

So first off, multiplication is the inverse of division, therefore, dividing r by 4 is the inverse of multiplying r by 4, so the answer is 4r.
