How does graphing help you solve a system of linear equations? i need the answer asap please

Answers

Answer 1
Its simply helps you visualizing what part is negative/positive. For inequations (ex: 3x+9>10), its super important to let you know from where to where the equation is, in my example, higher than 10.

What is the point-slope equation of a line if the slope is 3 and it passes through the point (-9, 2

Answers

Answer:

The point-slope equation of the line is y - 2 = 3(x + 9)

Step-by-step explanation:

The form of the point-slope equation is y - y1 = m(x - x1), where

m is the slope of the line(x1, y1) is a point on the line

∵ The slope of a line is 3

m = 3

∵ The line passes through point (-9, 2)

x1 = -9

y1 = 2

→ Substitute the values of m, x1, and y1 in the point-slope form

y - y1 = m(x - x1)

∴ y - 2 = 3(x - (-9))

→ Remember (-)(-) = (+)

∴ y - 2 = 3(x + 9)

The point-slope equation of the line is y - 2 = 3(x + 9)

Do the rates charged for life insurance remain the same throughout your life? Give some reasons why they may fluctuate or why they may remain the same.

Answers

Answer:

Yes

Step-by-step explanation:

Yes, when you purchase a life insurance policy you will be charged a certain rate but this can change if there are sudden changes in your health or as you get older. In some cases, you may purchase an insurance policy for a certain amount of years in which the rate is guaranteed to remain the same during that time. This type of policy's rate depends on the period of time you choose to be insured but once the time period is over the rate can increase a lot depending on your age and health at that time.

Marla's test scores were 93, 81, 77, and 97. What is Marla's test average?

Answers


Her test average was 87%

93 + 81 +77+97 = 348

348/4= 87

Answer:

87

Step-by-step explanation:

Hi!

First you add all of the numbers up together:

77+81+93+97= 348

Next, you divide the answer you got above by how many numbers are in your data set:

348/4 = 87

4 because 77,81,93,97 thats four numbers :)

Therefore, Marla's test average is 87!

So anytime you need find the average of any data set, you just add all the numbers together, then divide by the quantity of numbers there are.

Solve for x.
A
3x - 6
130°
8x+4

Answers

Answer:

x = 12

A = 30

Step-by-step explanation:

Here, we want to solve for the value of x

The angle at the top of the triangle is 8x + 4

The reason for this is because vertically opposite angles are equal

Mathematically;

8x + 4 + 3x - 6 = 130

The reason for this is that opposite interior angles equal the exterior angle

Thus;

8x + 3x + 4- 6 = 130

11x -2 = 130

11x = 130 + 2

11x = 132

x = 132/11

x = 12

The value of A is 3x - 6

A = 3(12)-6

A = 36-6

A = 30

Mr. Selan loves the 99-cent menu at Wendy's (sadly prices went up a few years ago). He used to buy two chicken sandwich at 99-cents each. With a tax of 8.5%, how much would he pay for the two sandwiches? Round your answer to the nearest cent​

Answers

Answer:

Mr. Selan would pay $2.15 for the sandwiches with tax.

Step-by-step explanation:

Given that:

Cost of each sandwich = 99 cents

Cost of two sandwiches = 99*2 = 198 cents

Sales tax = 8.5%

Sales tax = [tex]\frac{8.5}{100}*198=16.8\ cents[/tex]

Sales tax = 17 cents

Total cost = 198 + 17 = 215 cents

Total cost = $2.15

Hence,

Mr. Selan would pay $2.15 for the sandwiches with tax.

Step-by-step explanation:

1. a = ?   b = 16  c = 18

a² + b² = c²

a² + (16)² = (18)²

a² +  256 = 324

     - 256   -256

a² = 68

√a² = √68

a ≈ 8.25

2. a = 4     b = 8     c = ?

a² + b² = c²

(4)² + (8)² = c²

16 + 64 = c²

80 = c²

√c² = √80

c ≈ 8.94

Answer:

4187 cubic units

Step-by-step explanation:

According to the question;

radius (r) = 10 units

 π = 3.14

Volume of a sphere = 4/3*π*r^3

Substituting values;

V = 4/3*(3.14)*(10)^3

V = 4186.67 cubic units

pls show a graph, theres 4 to choose from.

Answers

Answer:

The required graph is shown below.

Step-by-step explanation:

Consider the given system of linear equations.

[tex]y=x+4[/tex]

Put x=0 in the above equation.

[tex]y=0+4[/tex]

[tex]y=4[/tex]

Now, put y=0 in [tex]y=x+4[/tex].

[tex]0=x+4[/tex]

[tex]x=-4[/tex]

The coordinates are (0,4) and (-4,0). Draw the line by using the points.

Similarly,

Consider the equation [tex]y = 3x - 1[/tex]

Put x=0 in the above equation.

[tex]y=3(0)-1[/tex]

[tex]y=-1[/tex]

Now, put y=0 in [tex]y = 3x - 1[/tex].

[tex]0=3x-1[/tex]

[tex]x=\frac{1}{3}[/tex]

The coordinates are (0,-1) and ([tex]\frac{1}{3}[/tex],0). Draw the line by using the points.

Consider the polynomial function g(x)=10x^9-50x^6-500x^2
What is the end behavior of the graph of g?

Answers

Answer:

It falls to the left and rises to the right.

Step-by-step explanation:

The polynomial function is given as;

g(x) =10x^(9) - 50x^(6) - 500x²

In this polynomial, the leading coefficient is 10. This is positive and also an even number and thus it means the graph will rise to the right.

Also, the degree of the polynomial is 9 since that's the highest degree of x. This degree is odd and it means the graph will point in the opposite direction to that of the leading coefficient. Thus, we can say it falls to the left.

So in summary, the end behavior of the graph of g is that it falls to the left and rises to the right.

The end behavior of the polynomial is:

When x ⇒ ∞, g(x) ⇒ ∞When x ⇒ -∞, g(x) ⇒ -∞What is the end behavior of the graph of g(x)?

The first thing you need to notice is that the degree of the polynomial is odd. This means that the function will have two opposite end behaviors.

Also, the leading coefficient is positive (is 10). So, when x tends to positive infinity, the end behavior of the function will tend to positive infinity.

When x tends to negative infinity, because the exponent is odd, the outcome will also be negative. Then here the end behavior of the function will tend to negative infinity.

Concluding, we can write:

When x ⇒ ∞, g(x) ⇒ ∞When x ⇒ -∞, g(x) ⇒ -∞

Graham spent a total of $15.05 on 10 apples and a packet of strawberries. If a packet of strawberries cost $2.55, how much did each apple cost? 15.05*10 + 2.55

Answers

Answer: $1.25

Step-by-step explanation:

Given

Graham spends a total of $15.05 on 10 apples and a packet of strawberries

Cost of strawberries packet $2.55

Suppose the cost of each apple is x

So, [tex]10x+2.55=15.05[/tex]

On solving

[tex]\Rightarrow10x=15.05-2.55\\\Rightarrow10x=12.5\\\Rightarrowx=\frac{12.5}{10}=\$1.25[/tex]

The cost of each apple is $1.25
