Answer:
x = 5
Step-by-step explanation:
-4x + 2 = -18
subtract 2 from both sides
-4x + 2 - 2 = -18 - 2
simplify
-4x = -20
divide both sides by -4
-4x/-4 = -20/-4
simplify
x = 5

Answer:
4289 kilometers squared
Step-by-step explanation:
This is an example of compounding. We start with the basic 4800 kilometers of land. We then find seven percent of the 4800 kilometers and subtract that same seven percent. If we are trying to find the area after twelve years, we must repeat this process twelve times. This does not mean that we find seven percent of 4800 then repeat subtracting the same amount. We need to fix the seven percent so that we can get seven percent of the amount we currently have.
With this in mind, we need to write a equation:
[tex]cv = cv/107[/tex]*
*Note that we are trying to find 93% of the current value (cv). We need to divide by 107%, not 7% (would be an illogical divisor). Then, when we divide by 107%, we have the 7% that we need to subtract by. There, we find the needed 93%
Now we can solve.
4800/107 = 45**(1)
4800 - 45 = 4755
4755***/107 = 44**(2)
***As mentioned earlier, we do not continue to subtract 45. We need to adjust to a new current value (cv).
4755 - 44 = 4711
4711/107 = 44**(3)
4711 - 44 = 4667
4667/107 = 44**(4)
4667 - 44 = 4623
4623/107 = 43**(5)
4623 - 43 = 4580
4580/107 = 43**(6)
4580 - 43 = 4537
4537/107 = 42**(7)
4537 - 42 = 4495
4495/107 = 42**(8)
4495 - 42 = 4453
4453/107 = 42**(9)
4453 - 42 = 4411
4411/107 = 41**(10)
4411 - 41 = 4370
4370/107 = 41**(11)
4370 - 41 = 4329
4329/107 = 40**(12)****
****Meaning that this is the last year
4329 - 40 = 4289
Your answer is 4289 kilometers squared.
Hope this helped.

The administration decided to do a census of all students at Blake Middle School by giving a survey to all students about the school lunches. http://frac.org/federal-foodnutrition-programs/school-breakfast-program/school-meal-nutrition-standards a. Name some questions that you would include in the survey. Explain why you think those questions would be important to ask. b. Read through the paragraph below that describes some of the survey results. Then, identify the population characteristics and the sample statistics. About 3 4of the students surveyed eat the school lunch regularly. The median number of days per month that students at Blake Middle School ate a school lunch was 18 days. 36% of students responded that their favorite fruit is bananas. The survey results for Tanya’s seventh-grade homeroom showed that the median number of days per month that her classmates ate lunch at school was 22, and only 20% liked bananas. The fiesta salad was approved by 78% of the group of students who tried it, but when it was put on the lunch menu, only 40% of the students liked it. Of the seventh graders as a whole, 73% liked spicy jicama strips, but only 2 out of 5 of all the middle school students liked them.

Find the missing dimension of the triangle.
Answer:
4.66 or 14/3
Step-by-step explanation:
Area of a triangle is (base × height)/2. They have given you the height and the area already, so:
14 = ( b × 6 ) / 2
28 = b × 6
4.66 = b
The base of the triangle is B = 4.667 feet or 14/3 feet
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the area of the triangle be represented as A
Now , the value of A is A = 14 feet²
Let the height of the triangle be H = 6 feet
Let the base of the triangle be B
And , area of the triangle = ( 1/2 ) x Length x Base
Substituting the values in the equation , we get
14 = ( 1/2 ) x 6 x B
On simplifying the equation , we get
14 = 3B
Divide by 3 on both sides of the equation , we get
B = 14/3 feet
Therefore , the base of the triangle is B = 4.667 feet
Hence , the base of triangle is 4.667 feet

Here is the graph for one equation in a system of equations:
a. Write a second equation for the system so it has infinitely many solutions.
b. Write a second equation whose graph goes through (0,1) so the system has no solutions
c. Write a second equation whose graph goes through (0,2) so the system has one solution at (4,1)
1) The equation that has infinitely many solution is y = -8/11·x + 4
2) The equation of the graph that has no solution is y = -8/11·x + 1
3) The equation of the line that has only one solution is y = -1/4·x + 2
Step-by-step explanation:
1) The points on the graph are;
(0, 4), and (5.5, 0)
The slope of the line defined by the given two points, we have;
(0 - 4)/(5.5 - 0) = -40/55 = -8/11
the equation of the straight line graph in point and slope form, we have;
y - 4 = -8/11 × (x - 0)
y - 4 = -8/11·x
For the equation for the system that has infinitely many solution, we have;
y = -8/11·x + 4
2) For the equation whose graph foes through the point (0, 1) and the system has no solution, we have;
An equation that has no solution with the equation y = -8/11·x + 4, is parallel to y = -8/11·x + 4, and therefore, the slope are equal
Therefore, the equation whose graph foes through the point (0, 1) and the system has no solution, in point and slope form is given as follows;
y - 1 = -8/11 × (x - 0)
y - 1 = -8/11·x
The equation of the graph that has no solution is therefore;
y = -8/11·x + 1
3) For the equation of the graph that goes through the point (0, 2), and has a common solution with the system at (4, 1), we have;
The slope of the graph is (1 - 2)/(4 - 0) = -1/4
The equation of the line that has only one solution with the system in point and slope form is given as follows;
y - 2 = -1/4×(x - 0)
y - 2 = -1/4·x
The equation of the line that has only one solution in standard form is therefore;
y = -1/4·x + 2
The second equation for the system so it has infinitely many solutions is [tex]y=-\dfrac{3}{4}x+1[/tex] and the second equation whose graph goes through (0,2) so the system has one solution at (4,1) is [tex]\rm y = -\dfrac{1}{4}x+2[/tex] and this can be determined by using the point-slope form of the line.
Given :
The graph of the line that passes through the points (4,1) and (0,4).
The equation of the line that passes through the points (4,1) and (0,4) is given by:
[tex]\dfrac{y-1}{x-4}=\dfrac{4-1}{0-4}[/tex]
Cross multiply in the above equation.
-4(y - 1) = 3(x - 4)
-4y + 4 = 3x - 12
3x + 4y = 16
[tex]\rm y = 4-\dfrac{3x}{4}[/tex] --- (1)
a) The second equation for the system so it has infinitely many solutions is given by:
Multiply equation (1) by 2 in order to determine the second equation.
[tex]\rm 2\times \left(y = 4-\dfrac{3x}{4}\right)[/tex]
[tex]\rm 2y = 8 - \dfrac{3x}{2}[/tex]
b) The second equation that passes through (0,1) and has a slope of -3/4 is given by:
[tex](y-1)=-\dfrac{3}{4}(x)[/tex]
[tex]y=-\dfrac{3}{4}x+1[/tex]
c) The second equation whose graph goes through (0,2) so the system has one solution at (4,1) is given by:
[tex]\dfrac{y - 2}{x-0}=\dfrac{1-2}{4-0}[/tex]
Cross multiply in the above equation.
4(y - 2) = -1(x)
4y - 8 = -x
[tex]\rm y = -\dfrac{1}{4}x+2[/tex]
