Consider the function f(x) = x2 + 2x – 15. What are the x-intercepts of the function?

Answer:

y = (1/3)x - 7/2

Step-by-step explanation:

Slope intercept form is y=mx+b, where m is the slope and b is the y intercept.

Lets transform this equation into that form using algebra rules.

-2/3x +2y = -7

get y alone

2y = (2/3)x - 7

divide everything by 2

y = (2/6)x - 7/2

simplify

y = (1/3)x - 7/2

Answer:

4L + 8 m = $40

5L + 2m = $28

Step-by-step explanation:

L = cost of a large plant

m = cost of a medium plant

4L + 8 m = $40

5L + 2m = $28

System of Equations : 8 M + 5 L = 40 ; 5 M + 2 L = 28

Given :  Cost of 4 large plants 'L' & 8 medium plants 'M' = 40

Cost of 5 large plants 'L' & 2 medium plants 'M' = 28

So, as per total cost, the equations are :

Answer:

Step-by-step explanation:

Hi there!

Given;

Total surface face (TSA)= 660cm²

Radius (r) = 5cm

Now;

TSA= 2πr( r + h)

   660cm²= 2*(22/7)*5 (5+h)

 660cm² = [tex]\frac{220}{7}[/tex](5+h)

[tex]\frac{660}{\frac{220}{7} }[/tex]= 5+h

h = 21-5

Therefore, the height of 16 cm.

Answer:

give me the brainliest

Step-by-step explanation:

Let x is the ones digit

Let y is the tens digit

Given that:

You use a total of 15 base ten blocks to show this number:

<=> x + y = 15 (1)

One of the digits is 6, so substitute into (1) we have another digit equals to: 9

Because the number of ones block is greater than the number of ten blocks

<=> y > x

<=> y = 9 and x= 6

So that number is: 69.

A Galileo thermometer (or Galilean thermometer) is a thermometer made of a sealed glass cylinder containing a clear liquid and several glass vessels of varying density. The individual floats rise or fall in proportion to their respective density and the density of the surrounding liquid as the temperature changes.

Answer:

t = 7

Step-by-step explanation:

[tex]t - 6 \times 2 + 5 = 0 \\ t - 12 + 5 = 0 \\ t - 7 = 0 \\ t = 7[/tex]

First, let's get the unit rate.

1.5 hours for 915 miles, so

[tex]\frac{1.5 hours}{915 miles} = \frac{1 hour}{x.miles}[/tex]

Cross multiplying gives us 1.5x = 915, divide by 1.5, and we get 610 miles. This is the answer for the top left. This means the plane was going 610 mph.

The speed will be constant because it tells us this.

     Then, we multiply 610 by the time to fill in the rest of the distances.

For t, we can figure out the distance is 610 times t, as you can see I have written down.

Answer:

m = -3/2

Step-by-step explanation:

Given the following points on the graph, (0, 9) and (2, 6):

Let (x₁, y₁) = (0, 9)

     (x₂, y₂) = (2, 6)

Plug these values into the following slope formula:

m = (y₂ - y₁)/(x₂ - x₁)

m = (6 - 9)/ (2 - 0)

m = -3/2

Therefore, the slope of the graph is -3/2. It has a negative value (hence, a negative slope) because the line is declining from the left side of the graph towards the right.

Rosa put an antiseptic cream on the cut on her finger to keep germs out of it.

An antiseptic is a substance that prevents the growth and development of microorganisms, such as bacteria, on living tissues.

When Rosa applied antiseptic cream to her cut finger, she aimed to create an environment hostile to germs. This action helps prevent infections and promotes the healing process.

The term antiseptic is derived from the Greek words "anti," meaning against, and septikos, meaning putrefying. Antiseptics are commonly used for cleaning wounds, disinfecting surfaces, and maintaining personal hygiene. They are milder than disinfectants, which are typically used on inanimate objects.

Rosa's choice of an antiseptic cream demonstrates her understanding of the importance of wound care. The cream likely contained substances that inhibit bacterial growth, such as hydrogen peroxide or iodine. By applying the antiseptic cream, Rosa effectively created a barrier against potential infections. It's crucial to clean and treat cuts promptly, as untreated wounds can lead to more severe health issues.

In summary, the use of an antiseptic cream by Rosa showcases her responsible approach to wound care. Antiseptics play a vital role in preventing infections and supporting the body's natural healing process. By applying an antiseptic cream, Rosa took a proactive step in safeguarding her health and ensuring the well-being of her injured finger.
