The value of total cost to buy school supplies is,

⇒ 25x dollars

The process or combination to combining two or more numbers is called the Addition.

Given that;

Notebooks cost 5x dollars, bottles of glue cost 2x dollars packs of markers cost 7x dollars and pens cost 3x dollars.

Here, Kent buys 2 notebooks, 3 bottles of glue 2 packs of markers and 3 pens.

Hence, Total cost is,

= 2 × 5x + 3 × 2x + 3 × 3x

⇒ 10x + 6x + 9x

⇒ 25x dollars

Thus, The value of total cost to buy school supplies is,

⇒ 25x dollars

Answer:

(5,0),(6,0)

Step-by-step explanation:

The x-intercept occurs when h(x) = 0

∴ let                  0 = (x – 5)(x – 6)                [using the knowledge that for the  

                                                                      produc to be 0, one of terms  

                                                                      must be zero]

⇒                 x - 5 = 0       ;      x - 6 = 0       [solve for x in each case]

⇒                      x = 5        ;           x = 6

Check:

If we graph the line we can see whether the intercepts are truly (5, 0) and (6,0). As seen below in the Desmos graph, it is.

Answer:

The total change in the helicopter's altitude is [tex]-58.3[/tex].

Step-by-step explanation:

Create an equation.

[tex]-42.9 +(-15.4)[/tex]

Adding two negative numbers is always negative, so simply add the absolute values and make the answer a negative.

[tex]42.9+15.4 = 58.3[/tex]

Now, change the answer to a negative.

[tex]-58.3[/tex]

Thus, [tex]-58.3[/tex] is the answer.

The answer is = 1 + sin x

Explanation

we need

a^2 - b^2 = (a+b) (a-b)

we use

cos^2 x + sin^2 x = 1

cos^2 x = 1 - sin^2 x = ( 1 + sin x) ( 1 - sin x )

therefore

cos ^2 x over 1 - sin x = 1+ sin x

Answer:

(x - 5)(x + 5)

Step-by-step explanation:

x² - 25 is a difference of squares and factors in general as

a² - b² = (a - b)(a + b) , then

x² - 25

= x² - 5²

= (x - 5)(x + 5)

10 year: $1000000

20 years: $2000000

Answer:

10 years = 8,900.00.

20 years = 23,200.00.

Step-by-step explanation:

Hey, let me tell you how to solve this; I had trouble as well.

Since the policy is worth 100,000, you divide this by 1,000.

That gives us 100.

Now, multiply 100 by the 10 yr cash value, which is 89.

That results in 8,900.00.

Taking 100 again, multiply it by the 20 yr cash value, 232.

That gives us 23,200.00.

Answer:

they is no answer because x-+20 is not applicable to math

Answer:

x = -20

Step-by-step explanation:

because there is no quadratic equation there

Answer:

313°

Step-by-step explanation:

No matter what number you substitute for the variable, the simplification will result is a false statement.

To isolate x, we will first subtract 0.8 from both sides.

0.6x + 0.8 = 1.4

-0.8 -0.8

0.6x = 0.6

Now all we have to do is divide both sides by 0.6, because it is the number besides x.

0.6x/0.6 = 0.6/0.6

x = 1

So you get the answer of x = 1.

Answer:

Well, you first want to find out what it is in decimal form, which in this case is 0.124. Then once you do that, you can convert it to an improper fraction, which would be 124/100, you then can simplify it to convert it into a mixed number, which lands you the final answer of 1 6/25 I hope this helps you! :)

Answer:

y = -1/5x

Step-by-step explanation:

Using the 'y=mx+c' form for the equation:

Find the slope (m):

Since the product of both slopes should be -1 (if they are perpendicular),

s₁s₂  = -1

5*s₂ = -1

s₂ = -1/5x

Hence, the slope (m) is -1/5x.

Substituting the slope value into 'y=mx+c':

y = -1/5x+c -----(1)

Substituting the point (-5,1) into the equation (1):

1 = -1/5 * (-5) + c

1 = 1 + c

c = 0

Substitiuting 'c=0' into 'y = -1/5x+c':

y = -1/5x

Hence,

y = -1/5x

Answer:

I'll assume "position 7" refers to distance and not to the order of other people.  

Step-by-step explanation:

We want an equation of the form y=mx+b, where m is the slope and b is the y-intercept (the value of y when x=0).  We can assume that "claps" is a new measure of distance.  0 claps is the finish.

Let's express the information provided in point format.

"At 2 claps, Joe is in position 7"  is (2,7)  2 is the distance (claps) and 7 is the time (minutes)

And we can say the rate is also the slope of a line.  "rate of 3 claps per minute" is 3c/m, where c is claps and m is minutes.

We can start a line equation by stating y = 3x + b, where we're using the rate, 3 c/m, as the slope, m.

We need to determine the value of b.  We can use the given point (2,7) and solve for m:

y = 3x + b

7 = 3*(2) + b

b = 1

The equation becomes y = 3x + 1

y is the distance in claps and x is the time in minutes.

At a time of 2 claps he is at position of 7.  b = 1 means he started 1 clap further from the finish at 0 claps.

To find the time required to reach the finish, we need to know the total distance, in claps.

Answer:

4 inches

Step-by-step explanation:

the middle number is 6 and the distance from 99.7 from the middle is 3 standard deviations. 12/3 =4

The value of 99.7% is the closest to the percentage of these heights that is within 3 standard deviations of the mean. The correct option is e.

If your distribution follows a normal distribution, the standard deviation and mean can tell you where the majority of the data are.

It is given that the heights of a large population of ostriches are normally distributed. The percentage of these heights is within 3 standard deviations of the mean.

As we know from the empirical rule:

It is the rule of 68-95-99.7.

From the data given in the question: The height of a large population of ostriches is normally distributed.

X ~ (u, б²)

Normal distribution.

P{u - 3б < X < u + 3б}

From the distribution table:

P{u - 3б < X < u + 3б} = 99.7%

Thus, the value of 99.7% is the closest to the percentage of these heights that is within 3 standard deviations of the mean.

#SPJ2

Step-by-step explanation:

A+B+C = 14

B+1 +B + B-2 = 14

3B -1 = 14

3B = 14+1

3B =15

B = 5

Therefore, A = 5+1 = 6 ft (option A)

__________

[tex] \: [/tex]

14 = A + B + C

14 = (B + 1) + B + (B - 2)

14 = 3b - 1

14 + 1 = 3b

15 = 3b

b = 15 ÷ 3

b = 5

A = B + 1

A = 5 + 1

A = 6✔ (A.)

Answer:

Step-by-step explanation:

1) f(x)=1/3(x+1)^2

so if we use the equation f(x)=a(x-h)^2+k then we can plug in the different things.  a would represent the compress/stretches, so in order to move horizontally, we would need to do 1/3

for h: that is the horizontal translations so, left and right. BUT remember it's the opposite. so if you want to go left <-- you would have to put a + sign and to go right you would have to put a - sign.

Using Cramer's rule it is found that Dx = -34.

In Cramer's rule, we have three matrices.

In this problem, the system is:

It's determinant is given by:

[tex]Dx = 6(-1) -(-4)(-7) = -6 - 28 = -34[/tex]

Thus, Dx = -34.
