Answer:

y=1/2x+1

Step-by-step explanation:

you need x1 y1 and x2 y2

In your problem x1 is -8

In your problem y1 is -3

In your problem x2 is 10

In your problem y2 is 6

you need to do y2-y1/x2-x1 so basically

6-(-3)/10-(-8)

which is 9/18 or 1/2x

Answer:

the unit rate is $2.25

Answer:

Step-by-step explanation:

Divide cost by length

The equation of the discount is (b) discount price = (original price)(1 – 0.12)

The discount is given as:

Discount = 12%

The equation of the discount price is then calculated as:

discount price = (original price)(1 – discount)

This gives

discount price = (original price)(1 – 12%)

Express 12% as 0.12

discount price = (original price)(1 – 0.12)

Hence, the equation of the discount is (b) discount price = (original price)(1 – 0.12)

Answer:

The ratio of side lengths is 4:15

The ratio of areas as a fraction is 16/225

Step-by-step explanation:

We can probably assume the triangles are similar. If that is the case, the smaller triangle is 4/15s the size of the blue triangle. That makes the ratio 4:15.

As for the ratio of areas, areas are expressed in length^2. Inches squared, centimeters squared, meters squared, or whatever length. It is always a length squared.

Similarly, the ratio of the length can be squared to give the ratio of the areas. The ratio of the areas is 4^2 / 15^2 = 16/225

Simplified Answer: 1/3 Non-Simplified Answer: 5/15

Step-by-step explanation:

Make every fraction have a common denominator:

4/5 * 3/3 = 12/15

3/15 = 3/15

2/3 * 5/5 = 10/15

Add and/or Subtract the numerator(s):

12 + 3 = 15

15 - 10 = 5

Place the final numerator over the denominator (Non-simplified Answer):

5/15

Simplify (What can you divide the numerator and the denominator by to make the fraction into it's simplest from without any remainders?):

5 goes into both 5 and 15.

5/15 divided by 5 = 1/3

Answer:

Yes, the ratio of friends who chose blue to the total asked is equivalent to the ratio of friends who chose green to the total asked.

Step-by-step explanation:

This can be determined as follows:

For Alex, we have:

Number of people who prefer blue = 4

The total asked = 6

Therefore, the ratio of friends who chose blue to the total asked can be calculated as follows:

Ratio of friends who chose blue to the total asked = Number of people who prefer blue / The total asked = 4 / 6 = 0.67

For Jordan, we have:

Number of people who prefer green = 8

The total asked = 12

Therefore, the ratio of friends who chose green to the total asked can be calculated as follows:

Ratio of friends who chose green to the total asked = Number of people who prefer green / The total asked = 8 / 12 = 0.67

Conclusion

From the calculations above, we have:

Ratio of friends who chose blue to the total asked = Ratio of friends who chose green to the total asked = 0.67

Since the ratio of friends who chose blue to the total asked is equal to the ratio of friends who chose green to the total asked is equal to 0.67, it therefore implies that the ratio of friends who chose blue to the total asked is equivalent to the ratio of friends who chose green to the total asked.

Answer:

-32 I THINK

Step-by-step explanation:

The y-intercept of the line passing through the given points is -5/2.

An intercept is a point on the y-axis, through which the slope of the line passes.

Given that, a line that passes through the point (1,-7) and (5, -25)

The equation of a line passing through two points is given by,

y-y1 = (y2-y1)/(x2-x1)(x-x1)

y+7 = -18/4(x-1)

y+7 = -9/2x+9/2

y = -9/2x+9/2-7

y = -9/2x-5/2

Hence, The y-intercept of the line passing through the given points is -5/2.

Answer:

A = 131.145 cm^2

Step-by-step explanation:

For this problem, we can see that this is an isosceles triangle.  This can be observed from two equal lengths.  Using this, let's apply the formula for the area of a triangle.

A = ( 1/2 ) * b * h

Note, we can say the base, b, is equal to 14 cm.  We simply need to find the height.  Using the idea of splitting the triangle into two right triangles, we can say the following based on the pythagorean theorem:

20^2 = (14 / 2)^2 + h^2

400 = 49 + h^2

400 - 49 = h^2

351 = h^2

18.735 = h

A = ( 1/2 ) * 14cm * 18.735cm

A = 131.145 cm^2

Hence, we have found the area of the triangle.

Cheers.

Undefined Slope

Step-by-step explanation:

If we look at the points given, then we can see that the X coordinates are the same. Putting this into (y2-y1)/(x2-x1), we can see that the denominator would be 0, meaning the slope would be undefined.

the value of g is 12.8.

To solve the equation g / 4 = 3.2 and find the value of g, we can multiply both sides of the equation by 4 to isolate g.

By multiplying both sides of the equation by 4, we have:

( g / 4 ) * 4 = 3.2 * 4

This simplifies to :

g = 12.8

Therefore, the value of g is 12.8. In the original equation, dividing g by 4 yields a quotient of 3.2, confirming that g = 12.8 is the solution that satisfies the equation g / 4 = 3.2.
