100 200 300

400

Number of US dollars

I

**Answer:**

The constant of proportionality of the graph is 0.75

**Step-by-step explanation:**

The coordinates of the points on the lines are;

(400, 300), (250, 187.5), and (120, 90)

Which can be written in a tabular form as follows;

Number of US dollars [tex]{}[/tex] Number of euros

120 [tex]{}[/tex] 90

250 [tex]{}[/tex] 187.5

400 [tex]{}[/tex] 300

Given that the graph is a straight line graph, we can represent the graph with the straight line equation, y = m·x + c

Where;

c = The y-intercept (where the graph meets the y-axis) = 0

m = The slope = The constant of proportionality

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

[tex]m =\dfrac{300-90}{400-120} = \dfrac{210}{280} = 0.75[/tex]

We have, y = m·x = 0.75·x.

Therefore, the constant of proportionality of the graph = 0.75.

Evaluate the given question.

**Answer:**

In this case since you have fraction you must make sure the limit x value does not make the denominator 0. In this case it **does**, so you have to factor the expressions to try to cancel out like terms when dividing. Use the method of factoring polynomials to find the solution. It is too late for me but I told you how you can answer it. Once you can plug in 2 into the denominator and not get 0, you can evaluate the limit.** Keep practicing! **

On Saturday, Kim's softball team will be having a family picnic. Hamburger patties

are sold at the local store with 12 patties in a package. Hamburger buns, however,

are only sold in packages of 9 hamburger buns. Kim's team wants to buy the exact

same number of packages for patties and buns

What is the least number of packages of patties and hamburger buns that Kim's

team should buy to have exactly the same number of patties as hamburger buns? If a

package of hamburger patties cost $4.98 and a package of hamburger buns cost

$2.16, what was the total expense?

**Answer:**

See below

**Step-by-step explanation:**

The patties (3 packs)

12x3= 36

The buns (4 packs)

9x4= 36

cost:

3x$4.98= $14.94

4x$2.16= $8.64

Add them to equal the total cost

= $ 23.58

solve the equation x²+11=36

**Answer:**

x=5

**Step-by-step explanation:**

Equation:

x^2 + 11=36

1.Subtract 11 on both sides

x^2 = 25

2. Square root 25

**x=5**

a printer can print 12 pages in 9 seconds what is the closest estimate of the number of pages it can print in 1 min

**Answer:**

estimated number of pages it can print will 80 in 1 min.

**Step-by-step explanation:**

If 12 pages/9 Seconds then by multiplying by 60 secs as there are 60 secs in 1 min.

we get

12/9 then multiply by 60 you will get 80 pages in 1 minute.

Number of pages a printer can print in 9 seconds = 12 pages

Number of pages than can be printed in 1 second =

= 12/9

= 1.3 pages

Number of pages that can be printed in 1 second = 0.75 page

Number of pages that can be printed in 1 minute =

= 1 minute = 60 seconds

Number of pages that can be printed in 60 seconds =

= 1.3 × 60

= 78 pages

Rounding off 78 , we get 80 .

Therefore , **8****0**** ****pages** can be printed in 1 minute .

can you solve this? :-5x =25

**Answer:**

**Step-by-step explanation:**

**-5x =25x **

Which equation shows a proportional relationship between x and y?

Answer: y = 4x

Step-by-step explanation:

A proportional relationship is function that is a means of ratio.

Say, x equals 12, then y would equal 48. Or x = 5, then y = 20. Etc

how do i graph 2x+4y=12

**Answer:**

(0,3) (6,0)

**Step-by-step explanation:**

What is an equation of the line that passes through the point (- 8, 0) and is parallel to the line x - 2y = 10 ?

4x+2y+10 = 0 can be rewritten as 2y = -4x-10 and dividing by 2 yields the slope/intercept form of y = mx+b

y = -2x-5

where -2 is the slope (m) and -5 the y-intercept (b)

the line we seek has that same slope, will pass through (7,3), but will have a different y-intercept. Plugging in 7 and 3 for x and y gives us

3 = -2(7)+b => 3 = -14+b => 17 = b making our new line’s equation:

y = -2x+17

An **equation** of the line that passes through the point (- 8, 0) and is **parallel** to the line x - 2y = 10 is y = -2x+17.

If the **slope** of a line is m and the y-**intercept **is c, then the **equation **of that **straight **line is given as:

y = mx +c

To find the **slope** of a line, we find the rate at which the value of 'y' is **increasing **as we **increase** the value of 'x' by one unit.

We know that 4x+2y+10 = 0 can be rewritten as 2y = -4x-10

Thus, dividing by 2 yields the **slope**/**intercept **form of y = mx+b

y = -2x-5

where, -2 is the **slope **(m) and -5 the y-**intercept **(b)

Now the **line **we has that same **slope**, will pass through (7,3), but will have a different y-**intercept**.

Then **Plugging** in 7 and 3 for x and y gives us;

3 = -2(7)+b

3 = -14+b

17 = b

Therefore, our new line’s **equation**:

y = -2x+17

in the school there is 1 boy for every 4 girls. there is a total of 11 boys how many girls are in choir

**Answer:**

There are 33 girls in choir

**Step-by-step explanation:**

4 x 11 = 44 (we get four from the 1 boy for every **4 **girls)

assuming that we have 44 kids in the class, 1/4 will be boys. 44/4 = 11 which means that we subtract 11 from 44 which will get you 33.

If there is a **total **of 11 boys. Then the **number **of girls in the **choir **will be 44 **girls**.

Find the slope of the table

**Answer:**

The slope should be -5/8

**Step-by-step explanation:**

The equation used to find the slope using a table is:

[tex]\frac{y2-y1}{x2-x1}[/tex]

To get the values, take two points from the table. For example:

(8, -5) and (16, -10)

Write and classify them as (x1, y1) and (x2, y2). Knowing that these values equal the numbers, put the numbers in the equation above, and you should find the slope.

Find the vertex of x²+18x+85

This is written of the form ax²+bx+c

a=1, b=18, c=85

The axis of symmetry is -b/2a

The axis of symmetry is the x term of your vertex (h,k)

So we have

h=-(18)/2

h=-9

k=f(-9) given that f(x) is x²+18x+85

(-9)²+18(-9)+85

81-162+85

-81+85

4

So your k value is 4

So because you’re vertex is (h,k) and since we found that h=-9 and k=4, your vertex is (-9,4)

Find the vertex of x²+18x+85

This is written of the form ax²+bx+c
