Answer:

x = 2, y = -1/3

Step-by-step explanation:

I'm pretty sure the question is asking for the values of x and y. By finding these values you will need to use elimination.

Equations given:

5x + 3y = 9

2x - 3y = 5

To find x:

5x + 3y + 2x - 3y = 9 + 5  (add to eliminate y to solve for x)

7x = 14

x = 2

To find y:

5(2) + 3y = 9

10 + 3y = 9

3y = -1

y = -1/3

Therefore, x = 2 and y = -1/3

Answer:

Extrapolation

Step-by-step explanation:

Given the regression equation :

pushups = 0.72 + 7.62 miles

Determining the Number of miles a person who does 24 push-ups should be able to run is an example of extrapolation, this is because we are making a prediction into the the future or outside our data based on the available information. Regression equations are used for extrapolation (making future predictions). Interpolation on the other hand makes estimation within the limit of the data usually between two known values.

Answer:

The percentage decrease in the number candid student pictures for the yearbook from 2015 to 2016 is approximately 9.3 percent

Step-by-step explanation:

The given data can be presented as follows

Year           [tex]{}[/tex]                      Number of Photos

2015           [tex]{}[/tex]                      236

2016           [tex]{}[/tex]                      214

The percentage decrease in the number of candid pictures is give by the following formula

[tex]Percentage \ Decrease = \dfrac{Original \ Value- New \ Value}{Original \ Value} \times 100[/tex]

Where;

Original value for the number of pictures = 236

New value for the number of pictures = 214

Substituting the values into the equation for the percentage decrease gives;

[tex]Percentage \ Decrease = \dfrac{236- 214}{236} \times 100 = \dfrac{550}{59} \ percent\approx 9.3 \%[/tex]

The percentage decrease is approximately 9.3 percent.

Answer:

The answer is 9.3%.

Answer:

Step-by-step explanation:

f(x) = a(x - h)² + k      - the  vertex form of the equation of the parabola with vertex (h, k)

[tex]f(x) = -16x^2+ 64x + 80\\\\f(x) = -16(x^2- 4x) + 80\\\\f(x) = -16(\underline {x^2-2\cdot2x\cdot2+2^2}-2^2) + 80\\\\f(x) = -16\big[(x-2)^2-4\big] + 80\\\\f(x) = -16(x-2)^2+64 + 80\\\\\bold{f(x)=-16(x-2)^2+124\quad\implies\quad h=2\,,\quad k=124}[/tex]

The vertex is (2, 124)

Answer:

10

Step-by-step explanation:

1 2 3 4 5

1 shakes hands with 2,3,4,5

2 shakes hands with 3,4,5 but not with 1 because they already shook hands once

similarly, 3 only shakes hands with 4 and 5, same reason as abov

4 with 5 only, same reason

Answer:

10

Step-by-step explanation:

Let the people be represented by numbers (1,2,3,4,5)

-- now 1 shakes hands with the remaining 4, (i.e 2,3,4,5)

-- 2 shakes hands with the remaining 3 (i.e 3,4,5) as it has already shaken hands with 1

-- 3 shakes hands with the remaining two  and so on

If you recognize the pattern there are 4+3+2+1 handshakes that have taken place, or 10 handshakes

Given :

To find the product of 183.5 and 10², move the decimal point in 183.5 _____ places to the right because 10² has _____ zeros.

To Find :

We need to fill the spaces.

Solution :

We know, when number with positive power of 10 is multiplied with another number we need to shift the number to the right hand side by the number of zeroes.

So, To find the product of 183.5 and 10², move the decimal point in 183.5 to right places to the right because 10² has two zeros.

Hence, this is the required solution.

Answer:

4

Step-by-step explanation:

As, the measure of one congruent side is = 2x + 3

So, bc there are 2 congrent sides, =( 2x + 3) + (2x +3) = 4x + 6

Now perimeter= the length of the 2 sides + third side

Perimeter = (4x + 6) + (7x) = 50 cm

So, 11x + 6 = 50

So, 11x = 50 - 6 = 44

11x = 44

x = 44/11

x = 4cm.

Answer:

C

Step-by-step explanation:

When talking about multiplication two negatives do, in fact, make a positive but if there is only one negative in the equation, the product(answer) will be negative. Therefore, C 31(-10)=-310 is the only problem that is correct.

Answer:

C.[tex]31\left(-10\right)=-310[/tex]

Step-by-step explanation:

Answer:

63/5 in improper form and 12 and 3/5 in mixed form

Step-by-step explanation:

f(x) = 2/5x + 11

Substitute in value of x for the equation

f(4) = 2/5(4) + 11

f(4) = 8/5 + 11

f(4) = 8/5 + 55/5

f(4) = 63/5 or 12 and 3/5

So, the answer should be 63/5 in improper form and 12 and 3/5 in mixed form.

Answer:

Step-by-step explanation:

f(x) = [tex]\frac{2}{5}x + 11[/tex]

f(4) = [tex]\frac{2}{5}*4 +11\\[/tex]

     [tex]=\frac{8}{5}+11\\\\=\frac{8}{5}+\frac{11*5}{1*5}\\\\=\frac{8}{5} + \frac{55}{5}\\\\=\frac{63}{5}\\\\=12\frac{3}{5}[/tex]

Answer:

The answer C  earn it

Answer:

1.5 years

Step-by-step explanation:

Simple Interest I = PRT

Principal = 2500, Rate R= 8.5%, SI = 318.75, T = ?

Now, substituting the above value

318.75 = 2500*0.085 * T

T = 318.75 / 2500*0.085 years

T = 318.75 / 2500*0.085 years

T = 318.75 / 212.5 years

T = 1.5 years

Answer:

Deana's claim is correct that the heart beats 4.8*10^3 times per hour.

Step-by-step explanation:

Given that human heart beats 80 time per minute.

In order to check Deana's claim we have to calculate number of beats in one hour.

As we know that

1 hour = 60 minutes

So the heartbeats in 60 minutes:

[tex]= beats\ per\ minute * 60\\=80*60\\=4800\ beats[/tex]

Converting the result into scientific notation gives us:

[tex]4800 = 4.8 * 1000 = 4.8*10^3\ beat[/tex]

Hence,

Deana's claim is correct that the heart beats 4.8*10^3 times per hour.

Answer:

Step-by-step explanation:

AD = DC and BE=EC ⇒

DE = 1/2AB

DE = 4*9 + 1 = 36 + 1 = 37

AD = DC

BE = EC

It gives that 2(DE) = AB

The length of DE.

According to the question,

2(DE) = AB

By putting the respected values, we get

2( 4x + 1 ) = 11x - 25

or, 8x + 2 = 11x - 25

or, 25 + 2 = 11x - 8x ( transposition method )

or, 27 = 3x

or, x = 27/3 = 9

The value of x is 9.

DE = 4(9) + 1 = 36 + 1 = 37

DE = 37
