find slope of the graph 9x-3y=15

Answers

ExplanationConvert the equation into slope-intercept form.

[tex]y = mx + b[/tex]

where m = slope and b = y-intercept.

What we have to do is to make the y-term as the subject of equation.

[tex]9x - 3y = 15 \\ 9x - 15 = 3y \\ \frac{9x - 15}{3} = y[/tex]

Simplify

[tex] \frac{9x}{3} - \frac{15}{3} = y \\ 3x - 5 = y \\ y = 3x - 5[/tex]

From y = mx+b, the slope is 3.

Answer

[tex] \large \boxed {slope = 3}[/tex]

ASAP determine whether the polygons are similar

Answers

Answer:

Not similar

Step-by-step explanation:

For two triangles to be similar , their sides should be in the same ratio. Here the sides are ,

First ∆ = 5 , 5 & 3 Second ∆ = 6 , 6 & 4

Ratio of first sides :-

= 6/5 = 1.2

Ratio of second sides :-

= 6/5 = 1.2

Ratio of third sides :-

= 4/3 = 1.33

Since the ratio of all three sides are not same , Hence the two triangles are not similar.

Hence the two triangles are not similar .

Find three consecutive integers such that the sum of twice the second integer and 4 times the third integer is two less than seven times the first integer.

Answers

Answer:

12,13 and 14

Step-by-step explanation:

Let the three consecutive integers be n, n+1 and n+2

ATQ,

The sum of twice the second integer and 4 times the third integer is two less than seven times the first integer.

[2(n+1)+4(n+2)] = 7n-2

or

2n+2+4n+8=7n-2

Taking like terms together,

6n-7n = -2-8-2

n = 12

So,

First integer = 12

Second integer = 12+1 = 13

Third integer = 12+2 = 14

Hence, three consecutive integers are 12,13 and 14.

Answers

Answer:

12

Step-by-step explanation

PEMDAS is key to solving. First you multiply 4*5 because its the first parenthesis we see, to get 20. Next we see that 1-2 is in a different parenthesis, so we get -2. So our current equation is 20-10-2-1+5. You just add/subtract in that order. 20-10=10 10-2=8 8-1=7 7+5=12 So your final answer is 12.

Step-by-step explanation:

Under her cell phone plan, Lily pays a flat cost of $55.50 per month and $4 per
gigabyte. She wants to keep her bill at $63.10 per month. Write and solve an equation
which can be used to determine x, the number of gigabytes of data Lily can use while
staying within her budget.
equation:
answer x=

Answers

Answer:

Equation : y = 4x + 55.50

x = 1.9 gigabytes

Step-by-step explanation:

Given that:

Flat fee per month = $55.50

Cost per gigabyte = $4

Let,

x be the number of gigabytes.

y be the total cost

y = 4x + 55.50

Lily wants to keep her bill $63.10

63.10 = 4x + 55.50

63.10 - 55.50 = 4x

4x = 7.60

Dividing both sides by 4

[tex]\frac{4x}{4} = \frac{7.60}{4}\\x=1.9[/tex]

Hence,

Equation : y = 4x + 55.50

x = 1.9 gigabytes

Answer:

Equation: 4x+55.5=63.1

Answer: x=1.9

Make 1/5 a fraction with a denominator of 45

Please show work

Answers

To make the denominator (5) 45, you need to multiply it by 9. If you multiply the denominator by 9, you also have to multiply the numerator by 9.

Therefore 1/5 = 9/45

Step-by-step explanation:

1/5

45÷5=9

so if 9 ×5 is 45 we need to times the whole fraction by 9.

1/5 ×1/9=1/45

James and Bethany Morrison are celebrating their 10th anniversary by having a reception at a local reception hall. They have budgeted $3500 for the reception. If the reception hall charges a $50 cleanup fee plus $34 per person find the greatest number of people that they may invite and still have within their budget.

Answers

Answer: See Below

Step-by-step explanation:

Create the equation:

$34 times the number of people plus the $50 cleaning fee has to be less than or equal to $3500

Or

34p + 50 <= 3500

34p <= 3450

p <= 101.470588....

We can have a part of a person attending the reception so we have to drop the remainder/decimal. Therefore the most amount of people that can attend the party and stay within budget is 101.

The number of bees in a hive doubles every year. A farmer starts a hive with 100 bees. After y years, the hive will contain B bees, where B = 100 · 2ʸ. How many bees will be in the hive after 3 years, assuming the hive continues to grow at this rate? (Answer must be in a complete sentence). *

Answers

Answer:

800 bees.

Step-by-step explanation:

If he starts with 100, after a year, it's 200, after another year, it's 400, and after a third year, it's 800.

It will be 800 bees in the hive after 3 years, assuming the hive continues to grow at this rate.

What are exponents?

The exponents of a number are defined as the representation of a number that shows how many times a number is multiplied by itself.

We are given that number of bees in a hive doubles every year. A farmer starts a hive with 100 bees.

After y years, the hive will contain B bees, where;

B = 100 · 2ʸ.

Therefore, after 3 years,  it will be;

B = 100 · 2³

B = 100 x 8

B = 800

Hence, It will be 800 bees in the hive after 3 years, assuming the hive continues to grow at this rate.
