The value of equation 4-2(x+7)=3(x+5) is that x=-5/7.

Given equation 4-2(x+7)=3(x+5)

We are required to  solve the equation for the value of variable x.

Equation is relationship between two or more variables expressed in equal to form.Equation of two variables looks like ax+by=c. It can be a linear equation,quadratic equation, cubic equation. It can be solved for finding the value of variables.

The given equation is 4-2(9x+2)=3(x+5)

It is a linear equation.

We have to first remove the brackets by multiplying the numbers to inside numbers.

4-18x-4=3x+15

Now collect variable x at one end and constant at other end.

-18x-3x=15-4+4

-21x=15

x=-15/21

x=-5/7

Hence the solution of equation 4-2(x+2)=3(x+5) is that x=-5/7.

Answer:

slope = - 1 , y- intercept = 2

Step-by-step explanation:

calculate the slope m using the slope formula

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with ( x₁, y₁ ) = (0, 2) and (x₂, y₂ ) = (2, 0) ← 2 points on the line

m = [tex]\frac{0-2}{2-0}[/tex] = [tex]\frac{-2}{2}[/tex] = - 1

the y- intercept is the point on the y- axis where the line crosses , so

y- intercept = 2

Answer:

Slope: -1

Y-intercept: 2

Step-by-step explanation:

The line crosses the y-axis at 2. and the slope would be -1 since going down by one unit, and the line going down would mean that it is negative.

Step-by-step explanation:

In the case above, the correct vectors are:

The solution for the Ship's vector are:

Note that the Horizontal aspect = 30 cos 30  

                                                   = 25.98.

For the  Vertical aspect = 30 sin(-30)

                                        = -15.

Hence it will be  <25.98, -15>.

In regards to the current's vector:

The Horizontal aspect=  5 sin 20

                                       = 1.71.

The Vertical aspect = 5 cos 20

The total number of light bulbs the company will make in weeks 9.36 × 10² is 4.27 × [tex]10^{6}[/tex] bulbs.

Work completed in a certain length of time is referred to as productivity (power). One hour, one minute, or one second makes to a unit.

Calculation for the total number of bulbs produced in given week;

Number of bulbs produced per week = 4.56 × 10³

Now, estimate how many bulbs will be produced in 9.36 × 10² weeks.

To estimate how many light bulbs were created in the allotted period, we will simply multiply both values.

Number of light bulbs the company will make in 9.36 × 10² weeks is;

= 4.56 × 10³ × 9.36 × 10²

= 4.27 × [tex]10^{6}[/tex]

Therefore, the total number of bulbs produced in weeks 9.36 × 10² is 4.27 × [tex]10^{6}[/tex] bulbs.

Step-by-step explanation:

the functional graph is the line.

a functional graph is always showing the direct relationship between a value on one coordinate axis with a value in the other coordinate axis

here it is between the price in dollars (as we can understand it : per unit) and the number of units sold.

clearly, the more units we sell, the cheaper we have to make the price per unit.

the question is how many units can be sold for a given price ($60).

so, I find the given price on the price axis (in this case the vertical axis), go then along that price all the way to the right until I hit the function line, and then go straight down to the unit axis and see what value I am hitting there : 80. which means 80,000 units.

so, I can sell 80,000 units for $60 per unit.

Using the Pythagorean Theorem, the perimeter of the triangle is of 58.7 cm.

The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:

[tex]h^2 = l_1^2 + l_2^2[/tex]

From your description, I will suppose that the legs are of 6 cm and 26 cm, hence the hypotenuse is:

[tex]h^2 = 6^2 + 26^2[/tex]

[tex]h = \sqrt{6^2 + 26^2}[/tex]

h = 26.7.

The perimeter is the sum of the lengths of the three sides, hence:

P = 26.7 + 26 + 6 = 58.7 cm.

The speed of the cart begin to decrease at approximately: 3.5 minutes.

A typical time-speed graph shows the time on the x-axis and the speed on the y-axis. When the slope is rising, it means the speed is increasing. When the slope is horizontal, it means the speed is constant. When the slope falls or decline, it means speed is decreasing.

We are given a time-speed graph that shows the speed of a cart over a period of several minutes. Time in minutes is on the x-axis (horizontal axis) while speed in miles per hour is on the y-axis (vertical axis).

From the graph given, the speed of the cart started increasing up to about 3 minutes, since the line slopes upwards. Then, between 3 and 4 minutes, we have a horizontal line which starts to decline at approximately 3.5 minutes.

Therefore, we can conclude that the speed of the cart begin to decrease at approximately: 3.5 minutes.

Answer:

1.) The slope is 2

2.) The y-intercept is (0,1)

3.) y = 2x + 1

Step-by-step explanation:

1.) you can either use rise over run or the slope formula. rise over run is quicker, but here's the formula:

you can use any two points on the line, i chose (2, 5) and (1, 3)

[tex]\frac{(y_{2}-y_{1})}{(x_{2}-x_{1})} \\[/tex]

[tex]\frac{3-5}{1-2} \\\\\frac{-2}{-1} \\\\\frac{2}{1} \\\\2[/tex]

2.) for the y-intercept, you just look for the point where the graph crosses the y-axis and x = 0

3.) using the formula y = mx + b, m being the slope and b being the y-intercept, you take the information above and plug it in to get y = 2x + 1

Dimensional analysis is the analysis of the relationships between different physical quantities by identifying their base quantities and units of measure and tracking these dimensions as calculations or comparisons are performed.

We can convert qt/min to gal/h as shown below:

1 qt = 0.25 gallon

1 min = 1/60 hour

4.5 qt/min = (4.5*0.25)/ (1/60) gal/h

= 4.5*0.25*60 gal/h

The number of campers this year (23) is equal to 2 times the number of last year (x), minus 11.

23 + 11 = 2x

Answer:

y=-2x+3

Step-by-step explanation:

Use the slope formula

[tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

According to the table, x=1 and y=1. There is another point x=2 and y=-1.

We can say that [tex]x_{1}=1[/tex] and [tex]y_{1} =1[/tex]. We can also say that [tex]x_{2}=2[/tex] and [tex]y_{2}=-1[/tex]. Plugging this into the equation we get:

[tex]m=\frac{-1-1}{2-1}=-2[/tex].

This means that the slope of your equation is -1/2

Point intercept form is y=mx+b

So plugging the slope in we have [tex]y=2x+b[/tex]

We can plug in one of the values from the value table for x and y, but to keep things simple, I’m going to just use x=1, and y=1, the first values on the table. Plugging these into the equation we get:

[tex]1=-2(1)+b\\ 1=-2 +b\\b=1+2 \\b=3[/tex]

So our equation is [tex]y=-2x+3[/tex]

Answer: A,C,D

Step-by-step explanation:

The equivalent equation of the given equation is 39x - 45 = 15x - 24.

Hence, option C) is the correct answer.

Given the equation; 3[x + 3(4x – 5)] = 15x – 24

We expand and collect like terms

3[x + 3(4x – 5)] = 15x – 24

3( x + 12x - 15 ) = 15x - 24

3x + 36x - 45 = 15x - 24

We add the like terms on both sides

39x - 45 = 15x - 24

Therefore the equivalent equation of the given equation is 39x - 45 = 15x - 24.
