x + 5 =2(x - 3)

Answer:

The answer is: w  =  − 30

Answer:

3.200×107 ​h​

Step-by-step explanation:

The function for the points are  y = -15x - 5

From the information given, we have that;

The points are;

(1/3,0) (-2 3/4,0) and (0,-5)

Using the point-slope form of a linear equation, we have;

y - y₁ = m(x - x₁)

Such that;

Using (1/3, 0) and (0, -5), we have that the slope is;

m = (0 - (-5))/0 -1/3)

expand the bracket

= 5 / (-1/3)

= -15

Now, take any of the given points and substitute the values

Using (1/3, 0), we get;

y - 0 = -15(x - 1/3).

y = -15x - 5.

The function for the points solved by  (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)

We have given the points:

(1/3,0) (-2 3/4,0) and (0,-5)

Using the formula of linear equation

\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)                                                          

Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)

that is 1/3 = \(a\), 0 = \(a_{1}\) and

0 = \(b\), -5 = \(b_{1}\)

\(x\) refers to the slope of line (take any variable)

Now for finding the value of \(x\),

\(x=a-a_{1}/b-b_{1}\)

inserting the values,

\(x=[0-[-5]]/[0-1/3]\\x= -15\)

Substitute the value of \(x\) in the equation

\(a-0=-15[b-1/3]\)

By simplifying the equation, we get

\(a=-15b-5\)

Answer:

16/63

Step-by-step explanation:

Given problem,

→ (8/9) × (2/7)

Let's solve the problem,

→ (8/9) × (2/7)

→ (8 × 2)/(9 × 7)

→ 16/63

Hence, answer is 16/63.

It's - b + a

Because we're going down the arrow on b or the opposite direction of b. Then, up to C where its vector is a as it lies half way on AC with half of the line labelled a. So, the other half must be also a.

Answer: Rational

Step-by-step explanation:

The number -0.8 is rational if it is an integer or decimal

A rational number is a number that can be represented as a/b where a and b are integers and b is not equal to 0.

Since -0.8 is an integer or decimal from above, -0.8 is also a rational

An irrational number is a number that cannot be expressed as a ratio between two integers and is not an imaginary number.

Answer:

It is a rational number

Step-by-step explanation:

An irrational is a number that repeats in a sequence or not.

It is a number that never stops. ex. pi, 2/3.

Since $30 is 3 times the $10 then you multiply the 5 by 3 and it comes out to 15lb of meat

Answer:

A, B, ad C

In order to find the ratio of something you must:

Add the parts of the ratio to find the total number of parts.

Find the value of each part of the ratio by dividing the number by the total number of parts calculated in step 1.

Multiply each part of the original ratio by the value of each part calculated in step 2.

Answer:

10cm

Step-by-step explanation:

If you want to find one of the heights of the triangle, you need to use some math magic. The magic spell is:

A = (1/2) * b * h

where A is the area, b is the base, and h is the height. Don't ask me why, it just works.

Now, we know that the area of triangle ABD is 50 cm and one of its sides is 10 cm. We can pretend that this side is the base of the triangle. Why? Because it makes our life easier. Trust me.

Then we put these numbers into the magic spell and we get:

50 = (1/2) * 10 * h

Now we need to solve for h, which is the height we want. To do that, we need to do some algebra. Don't worry, it's not that hard. Just follow these steps:

- Multiply both sides by 2. This gives us:

100 = 10 * h

- Divide both sides by 10. This gives us:

10 = h

- Celebrate! We found the height!

So, one of the heights of the triangle is 10 cm. Isn't math fun?

Answer:

Step-by-step explanation:

Each Exterior angle = 180° - Interior angle.

(3m + 12)° = 180° - (5m − 16)°

Then solve algebraically:

\(3m+12=180-5m-16\)

\(3m+12=-5m+164\)

\(8m+12=164\)

\(8m=152\)

m = 19

The value of m will be 23.

What is mean by Triangle?

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

Given that;

In triangle XYZ,

⇒ m ∠Z = (5m − 16)°

And, the exterior angle to ∠Z measures (3m + 12)°.

Now,

Since, The sum of angle and its exterior angle in a triangle will be 180°

Hence, We can formulate;

(5m − 16)° + (3m + 12)° = 180

Solve for m as;

5m - 16 + 3m + 12 = 180

8m - 4 = 180

8m = 180 + 4

8m = 184

m = 23

Thus, The value of m will be 23.
