### Answers

$12.75 divided by 15 pens = $0.85 per pen

$17.40 divided by 20 pens = $0.87 per pen

the first store has the lower price for pens. when you calculate the price of one singular pen, the first store sells them for $0.85 however the second store sells them for $0.02 more ($0.87)

Does the equation y=x reporestent a function. Explain why

first person to solve gets brailiest

### Answers

**Answer:**

yes because When you are given an equation and a specific value for x, there should only be one corresponding y-value for that x-value. For example, y = x + 1 is a function because y will always be one greater than x. Equations with exponents can also be functions.

**Step-by-step explanation:**

The notation y = f(x) defines a function named f. This is read as “ y is a function of x.” The letter x represents the input value, or independent variable. The letter y, or f(x), represents the output value, or dependent variable.

Alex and Jordan asked some friends about their favorite colors. Alex found that 4 out of 6 people prefer blue, and Jordan found that 8 out of 12 people prefer green. Is the ratio of friends who chose blue to the total asked equivalent to the ratio of friends who chose green to the total asked? Explain.

### Answers

**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:**

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

find the area and height of a triangle 20cm 20cm 14cm

### Answers

**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.

what is the y- intercept of a line that passes through the point (1,-7) and (5, -25)

### Answers

**Answer:**

-32 I THINK

**Step-by-step explanation:**

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

What is y-intercept?

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.

A clothing shop is offering a 12 percent discount for senior citizens. Which equation represents the discount price?

discount price = 1 - (original price)(0.88)

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

discount price = (original price)(0.12)

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

### Answers

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

How to determine the discount price?

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: B**

**Step-by-step explanation:**

Solve the equation.

g/4 =3.2

g=?

### Answers

4g/4 = 3.2(4)

g = 12.8

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.
