Answer:

i dont know

Step-by-step explanation:

Answer: 5;12;13

Step-by-step explanation:

let's call the shortest leg

[tex]x[/tex]

and then the longer leg and the hypotenuse

[tex]2x + 2[/tex]

[tex]2x + 3[/tex]

respectively, and then apply pythagorean theorem to the triangle:

[tex]x^2+(2x+2)^2=(2x+3)^2[/tex] at this point is simple number crunching;

[tex] x^2+4x^2+8x+4=4x^2+12x+9 \\ x^2-4x-5=0 \rightarrow (x-5)(x+1)=0[/tex]

the only valid solution is obviously x=5 since its a length of a segment.

Answer:

y - 1 =  -2(x - 3)

Step-by-step explanation:

Given the point, (3, 1) and the slope of –2:

Let  (x₁, y₁) = (3, 1)

slope: m = -2

Substitute these values into the following point-slope form:

y - y₁ = m(x - x₁)

y - 1 = -2(x - 3)  ⇒ This is the point-slope form.

Answer:

8x + 4y

Step-by-step explanation:

3(x + y) + 5x + y

3x + 3y + 5x + y....... distribute 3 to both variables in the parenthesis

8x + 4y....................... combine like terms

Answer

8x+4y

Step-by-step explanation:

First you expand the 3(x+y) by multiplying 3 with x+y

So it becomes 3x+3y

Now your new expression will be 3x+3y+5x+y

After that, you combine the like terms, 3x and 5x are like terms, 3y and y are like terms.

So it will become 3x+5x+3y+y

You can add the like terms up, so 3x+5x=8x and 3y+y =4y

The simplified expression will be 8x+4y

The size of angle x from the figure is 16 degrees

The sum of the interior angle of a triangle is 180 degrees, hence to get the value of X, we will take the sum of all the given angles and equate them to 180 degrees.

127 + 37 + X = 180

164 + x = 180

Subtract 164 from  both sides

164 + x - 164 = 180 - 164

x =16 degrees

Hence the size of angle x from the figure is 16 degrees

Answer:

As we know that the sum of interior angles of triangle is 180⁰.

Accounting to the question :

[tex]\implies[/tex] Sum of angles = 180⁰

[tex]\implies[/tex] 127⁰ + 37⁰ + X = 180⁰

[tex]\implies[/tex] 164⁰ + X = 180⁰

[tex]\implies[/tex] X = 180⁰ - 164⁰

[tex]\implies[/tex] X = 16⁰

Hence, the size of angle is 16⁰.

Answer:

Step-by-step explanation:

To solve this, what you first should do is make one of the variables equal, that way you can eliminate that variable and only have to solve one of them. Let's eliminate y, since that one is easier. As you can see, the y in the first equation is 3 times less than the y in the second, so you would multiply everything the first equation by 3 to help eliminate y. After doing this, you would have -6x + 3y = 48, with which you will add to the second equation, which leaves you with -10x = 50. Since you have a negative x, multiplying both sides by a negative sign will make it much easier to find x's value, which gives you -5 as x's value, so x = -5. Now keep this aside, because it will help you solve.

     Now that you have the value of x (-5), you should replace one of the equations with x's value, so let's just do this to the second equation. Now you have 20 - 3y = 2. Here, you should take the 20 to the right side to isolate 3y from the numbers, which leaves you with -3y = -18. This gives tells you, after simplifying, that y = 6.

     And since the order pair is always (x,y), your answer would be (-5, 6). STILL EDITING ANSWER!

Answer:

2x - y = - 8

Step-by-step explanation:

y - 4 = 2(x + 2) ← distribute

y - 4 = 2x + 4 ( subtract y from both sides )

- 4 = 2x - y + 4 ( subtract 4 from both sides )

- 8 = 2x - y , that is

2x - y = - 8 ← in standard form

with A = 2, B = - 1 and C = - 8

Step-by-step explanation:

Since the monthly fee is $4.25

so

● $4.25 + ( 2.75 × Number of hours) = 40

The equation, 35=n/7 represents this sentence "35 is the quotient of a number and 7".Option D is correct.

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that, sentence 35 is the quotient of a number and 7.

The number being divided is referred to as the dividend, and the number being divided by it is referred to as the divisor. The quotient is the outcome of the division.

35 is the quotient of a number and 7.

Quotient = 35

Number = n

Another number = 7

The equation represents this sentence is,35 = n/7

Thus, the equation, 35=n/7 represents this sentence "35 is the quotient of a number and 7."Option D is correct.

Answer:

0.75x-3

Step-by-step explanation:

If Athlete J continues at that speed, it will take 12 minutes to run 1 mile

It will take Athlete J 60 minutes to run 5miles

Since the speed of Athlete H is greater than that of J, hence Athlete H runs faster.

The formula for calculating the speed of the athlete is expressed as:

Speed = Distance/Time

1) If Athlete J runs 2/3 of a mile in 8 minutes, this can be expressed as:

2/3 miles = 8 minutes

If the athlete runs for 1 mile, then;

1 mile = x

Divide both expressions

2/3 = 8/x

2x = 24

x = 12 minutes

Hence If Athlete J continues at that speed, it will take 12 minutes to run 1 mile

2) if athlete J run 5 miles, the time taken will be expressed as;

2/3(5) = 8/x

2/15 = 8/x

2x = 120

x = 60minutes

Hence it will take Athlete J 60 minutes to run 5miles

3) If Athlete H runs 2 3/4 miles in 1/2 hour, then the speed of athlete H will be expressed as:

Speed = (2 3/4)/0.5

Speed = 2.75/0.5

Speed = 5.5miles/hr

For Athlete J;

Speed = 5/1

Speed = 5 miles/hr

Since the speed of Athlete H is greater than that of J, hence Athlete H runs faster.

Step-by-step explanation:

To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. For example, lets find the intercepts of the equation y = 3 x − 1 \displaystyle y=3x - 1 y=3x−1. To find the x-intercept, set y = 0 \displaystyle y=0 y=0.

1.To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y.

2.To find the x-intercept, set y = 0 \displaystyle y=0 y=0.

3.To find the y-intercept, set x = 0 \displaystyle x=0 x=0.

Equivalent Expression:  [tex]\displaytext\mathsf{\frac{a^7}{b^8}}[/tex]

Step-by-step explanation:

Given the exponential expression,  [tex]\displaystyle\mathsf{\frac{a^{12}\:b^{-3}}{a^{5}\:b^{5}}}[/tex]:

We could use the Quotient Rule of Exponents where it states that:

[tex]\displaystyle\mathsf{\frac{a^m}{a^n}\:=\:a^{(m\:-\:n)}}[/tex]

Since we have the variables, a and b as the base, we could simply apply the Quotient Rule and subtract their exponents.

[tex]\displaystyle\mathsf{\frac{a^{12}\:b^{-3}}{a^{5}\:b^{5}}\:=\:a^{(12\:-\:5)}\:b^{(-3\:-\:5)}}[/tex]

[tex]\displaytext\mathsf{=\:a^{7}\:b^{-8}}[/tex]

Next, we must transform the negative exponent of base, b, into positive by applying the Negative Exponent Rule, where it states that:

[tex]\large\text{$ a^{-n}\:=\:\frac{1}{a^{n}} $}[/tex]

Applying the Negative Exponent Rule will result in the following exponential expression:

[tex]\LARGE\text{$ a^{7}\:b^{-8}\:=\:[a^{7}\:\times\:\frac{1}{b^8}]\:=\:\frac{a^7}{b^8} $}[/tex]

Therefore, the equivalent expression is:  [tex]\LARGE\text{$ \frac{a^7}{b^8} $}[/tex].

Answer: 8

Step-by-step explanation:

Rewriting input as fractions if necessary:

1/8, 1/4

For the denominators (8, 4) the least common multiple (LCM) is 8.

LCM(8, 4)

Therefore, the least common denominator (LCD) is 8.

Calculations to rewrite the original inputs as equivalent fractions with the LCD:

1/8 = 1/8 × 1/1 = 1/8

1/4 = 1/4 × 2/2 = 2/8
