Equation A: y = -9x + 14

Equation B: y = x - 6

What is the solution ( , ) to the given set of equations?

Answers

Answer:

compare both the equation we get,

X-6 = -9x+14

or, 10X =20

or, X= 2

Y=X-6

or, Y= 2-6

or, Y= -4

hence the solution is (2,-4)

Benjamin has 16 coins in his wallet consisting of quarters and dimes. The total worth of
the coins is $3.10. Benjamin created two linear equations to model this scenario, where
q represents the number of quarters in his wallet, and d represents the number of
dimes.

Answers

Answer:

6 dimes & 10 quarters

Step-by-step explanation:

Here are the two equations. The first one deals with the numbers of coins. The second one deals with the values of the coins.

d + q = 16

0.1d + 0.25q = 3.1

Solve the first equation for d and plug into the second equation.

d = 16 - q

0.1(16 - q) + 0.25q = 3.1

1.6 - 0.1q + 0.25q = 3.1

0.15q = 1.5

q = 10

d + q = 16

d + 10 = 16

d = 6

Answer: 6 dimes & 10 quarters

Benjamin has 6 dimes and 10 quarters.

What is linear equation?

A linear equation is  defined as an equation in which the highest power of the variable is always one.

Given that two equations,

d + q = 16

0.1d + 0.25q = 3.1

Where q represents the number of quarters in his wallet, and d represents the number of dimes.

d = 16 - q

0.1(16 - q) + 0.25q = 3.1

1.6 - 0.1q + 0.25q = 3.1

0.15q = 1.5

q = 10

d + q = 16

d + 10 = 16

d = 6

Hence Benjamin has 6 dimes and 10 quarters.

Automobiles traveling on a road with a posted speed limit of 65 miles per hour are checked for speed by a state police radar system. The following is a frequency distribution of speeds. Speed (miles per hour) Frequency 45 up to 55 50 55 up to 65 325 65 up to 75 275 75 up to 85 25 picture Click here for the Excel Data File The mean speed of the automobiles traveling on this road is the closest to ____.

Answers

Answer:

The mean speed of the automobiles traveling on this road is the closest to 64 miles per hour

Step-by-step explanation:

Given

[tex]\begin{array}{cc}{Speed} & {Frequency} & {45-55} & {50} & {55-65} & {325} & {65-75} & {275} & {75-85} & {25} \ \end{array}[/tex]

Required

Calculate the mean

First, calculate the midpoint (x)

For 45 - 55: [tex]x = \frac{1}{2}(45+55) = 50[/tex]

For 55 - 65: [tex]x = \frac{1}{2}(55+65) = 60[/tex]

For 65 - 75: [tex]x = \frac{1}{2}(65+75) = 70[/tex]

For 75 - 95: [tex]x = \frac{1}{2}(75+85) = 80[/tex]

So, we have:

[tex]\begin{array}{ccc}{Speed} & {Frequency} & {x} & {45-55} & {50} & {50} & {55-65} & {325} & {60} & {65-75} & {275} &{70} & {75-85} & {25} &{80}\ \end{array}[/tex]

The mean is then calculated as:

[tex]\bar x = \frac{\sum fx}{\sum f}[/tex]

[tex]\bar x = \frac{50*50+325*60+275*70+25*80}{50+325+275+25}[/tex]

[tex]\bar x = \frac{43250}{675}[/tex]

[tex]\bar x = 64.07[/tex]

[tex]\bar x = 64[/tex] --- approximated

Answer:

90 mm^2

Step-by-step explanation:

split into two rectangles.

First rectangle: 5 x 6 = 30 mm^2

Second rectangle: 10 x 6 = 60 mm^2

30 + 60 = 90 mm^2

Answer:

90 [tex]mm^{2}[/tex]

Step-by-step explanation:

Hi!

What we have over here is a composite figure.

Basically, it's made up of different shapes

We can either make a rectangle by making a horizontal line from the point in between 6 mm and 5 mm

Or we can make a rectangle by going verticle from the point in between        6 mm and 5 mm

Either way, we have two rectangles now, and we can use our formula [tex]l*w[/tex] to find the area.

For the first example, we would do:

[tex]6*5[/tex] [tex]=30[/tex]

[tex]6*10=60[/tex]

Then we add the two areas of the two rectangles:

[tex]60+30=90[/tex] [tex]mm^{2}[/tex]

For the second example, we would do:

[tex]5*6=30[/tex]

[tex]5*12=60[/tex]

[tex]60+30=90[/tex] [tex]mm^{2}[/tex]

Just cut the figure into shapes you can calculate the area of and you should be good to go!

LM; 13-12/13-6 = 1/7

MN: 8-13/9-13 = 5/4

Since angles and sides opposite one another on a parallelogram are congruent, we can say this is a parallelogram because there are congruent.
