Therefore -2m + 6 = 14

Answer:

y - 2 = 3(x + 5)

Step-by-step explanation:

The given equation has slope -1/3.  Any line perpendicular to the given line has a slope which is the negative reciprocal of -1/3, which comes out to +3.

Use the point-slope formula y - k = m(x - h):

y - 2 = 3(x + 5)

The two Integers are  [tex]10,10.[/tex]

An Integer number that can be written without a fractional component.

We have,

Sum of two Integers [tex]=20[/tex]

Product of two Integers [tex]=100[/tex]

Now,

Let,

One integer [tex]=x[/tex]

Another integer [tex]=y[/tex]

So,

According to the question,

[tex]x+y= 20[/tex]     [tex].....(i)[/tex]

[tex]x*y=100[/tex]

⇒ [tex]x=\frac{100}{y}[/tex]     [tex].....(ii)[/tex]

Now,

Putting value of x in equation (i),

We get,

[tex]\frac{100}{y}+y= 20[/tex]

[tex]100+y^2=20y[/tex]

[tex]y^2-20y+100=0[/tex]

Using middle term split method,

[tex]y^2-10y-10y+100=0[/tex]

[tex]y(y-10)-10(y-10)=0[/tex]

[tex](y-10) (y-10)=0[/tex]

We get,

[tex](y-10)=0[/tex] and [tex](y-10)=0[/tex]

So, [tex]y=10[/tex]

Now, putting value of y in in equation (i),

[tex]x+10=20[/tex]

[tex]x=10[/tex]

So, two integers are [tex]10,10.[/tex]

Hence, we can say that the two Integers are  [tex]10,10.[/tex]

Answer:

12/25=48%

Step-by-step explanation:

total=denominator=12+13=25

numerator=no of cherries=12

12/25=x/100

1200=25x

x=48%

A percentage is a number or ratio that represents a fraction of 100. 

Percentage formula = (Required number / Total number) x 100

The percentage of cherries is 48%.

A percentage is a number or ratio that represents a fraction of 100. 

Example:

50% = 50 /100 = 1/2

25% = 25/100 = 1/4

We have,

Number of cherries = 12

Number of strawberries = 13

The total number of fruits:

= 12 + 13

= 25

Percentage formula = (Required number / Total number) x 100

The percentage of cherries:

= (Number of Cherries / Total number of fruits) x 100

= (12 / 25) x 100

[ 25 x 4 = 100 ]

= 12 x 4

= 48%

Thus,

The percentage of cherries is 48%.

Answer:

12

Step-by-step explanation:

We know that 8x3=24, so we have to find what would equal 3 in the parenthesis.

12-9=3

The correct equation would be 8 (12-9) =24, or to be very simple, 8x3=24.

So y=12.

Answer:

133.33g

Step-by-step explanation:

Let the:

Mass of 1.2g/cm³ of liquid = x

Mass of 1.8g/cm³ of liquid = y

From our Question above, our system of equations is given as:

x + y = 400........ Equation 1

x = 400 - y

1.2 × x + 1.8 × y = 1.6 × 400

1.2x + 1.8y = 640..... Equation 2

We substitute, 400 - y for x in Equation 2

1.2(400 - y) + 1.8y = 640

480 - 1.2y + 1.8y = 640

- 1.2y + 1.8y = 640 - 480

0.6y = 160

y = 160/0.6y

y = 266.67 g

Solving for x

x = 400 - y

x = 400 - 266.67g

x = 133.33g

Therefore, the mass of the liquid of density 1.2g/cm³ is 133.33g

Answer:

Equation D, y = 1.75x + 6.25

Step-by-step explanation:

We know that the common ratio is 1.75 which means that the data would go up by $1.75 each time and then an additional of 6.25 is also there. Hence, 1.75 would be the slope and 6.25 would be the intercept of the equation.

Step-by-step explanation:

find the volume

find 80% of whats left

divide by 1.75 (gas price)

sorry if its wrong but im human

will give you the steps but try to do the problem by yourself.  

Start by finding the volume of the tank

Multiply 1.75 ft and 1.25 ft then covert the sum to inches by multiplying it by 12.

Then multiply that amount by the ll inches and you have the volume.

Since the tank is 20% full divide the volume by five, take the number you get from that and subtract it from the origanl volume.

Now you have the amount you need to fill.

Since it is 3.

Divide the amount you need to fill by 77 and you get the cost to fill the tank.

Answer:yˆ=−0.175x2−3.786x+121.119

look at picture

Step-by-step explanation:

The quadratic regression equation for the data set is:

y^ = -0.175x²-3.786x+121.119

Quadratic regression is the process of determining the equation of a parabola that best fits a set of data. This set of data is a given set of graph points that make up the shape of a parabola. The equation of the parabola is y = ax² + bx + c, where a can never equal zero.

According to the given problem,

Let us choose any value of x,

x = 10

For this value of x we can see that the respective value of y= 50

Substituting the value of x in the equations to see which equation satisfies the value of y as 50.

Substituting the value of x in the equation:

y^ = -0.175x²-3.786x+121.119

y^ = 50

Hence, we can conclude that y^ = 0.175x² - 3.786 + 121.119 is the quadratic regression equation for the given data set.
