Step-by-step explanation:
-4(4x-9)=2x
-16x+36= 2x
-16x - 2x = -36
-18x = -36
x = 2
Answer:
x = 2
Step-by-step explanation:
-4 (4(2)-9)=2x
-4 (8-9) = 2x
-4 (-1) = 2x
4 = 2x
divide by 2
2 = x
Express the statement "A rectangular field with an area of 120m' has it length 12mn longer than the width" as quadratic equation.
Answer:
The quadratic equation is x^2 -12x -120 = 0
where x represents the length of the field
Step-by-step explanation:
We want to make an expression in terms of a quadratic equation;
Let the length of the field be x mm , then the width will be (x-12) mm
Mathematically , the area of the field will be L * B
Thus;
x * (x-12) = 120
That gives;
x^2 -12x = 120
x^2 -12x -120 = 0

How does the side length of the square relate to the square root?
Answer:
The sides can be found by taking the square root of the area. , where = side.
Step-by-step explanation:
Answer:
the area of any quadrilateral can be determined by multiplying the length of its Base by its height. since we know the shape here is square we know that all sides are of equal length. from this we can work backwards by taking the square root of the area to find the length of one side.

Which of the following tables represents the rule, y equals seven less than four times a number?
Answer:
the second table.
Step-by-step explanation:
I used process of elimination to determine which one fits.
here's how I know I'm correct:the rule is, y = 4x - 7
if you put in the numbers from table 2
-3 = 4(1) - 7
-3 = 4-7
-3 = -3
13 = 4(5) - 7
13 = 20 - 7
13 = 13

Step-by-step explanation:
Mr. and Mrs. Wagner are getting ready to drive across the USA from Philadelphia, PA to Los Angeles, CA in five days. The distance is approximately 3,000 miles. The average price of gasoline is about $2.10 per gallon. They plan to stay in a hotel for four nights and budget the cost of meals be about $45 per day per person.
Answer:
(a) $ 84.
Step-by-step explanation:
Given that, the distance between the PA to CA = 3000 miles.
Time of travel, t = 5 days.
The average price of gasoline, r = $ 2.10/ gallon
Cost of meal for one person, c = $ 45/ day
Total number of persons, n = 2 (Mr. and Mrs. Wagner)
(a) The average of van = 75 mpg.
So, to cover 75 miles, the amount of gasoline required = 1 gallon
By using the elementary method, the amount of gasoline required to cover 1 mile = 1/75 gallons.
So, the amount of gasoline required to cover 3000 miles
= (1/75)x 3000= 40 gallons.
Now, cost for gasoline = 40 x 2.10=$84
Hence, the total cost of the gas for the trip is $84.
Identify the equation of the graph.

What is the slope of the line that passes through the
points (-4, 10) and (2, 22).
Answer:
2
Step-by-step explanation:
slope= (y2-y1)/x2-x1)
= (22-10)/(2--4)
= 12/(2+4)
= 12/6
=2
If 2x + 11 = 3x + 4, then x

Reduce: -8/40 (pls answer)
Answer:
-1/5
Step-by-step explanation:
The first step you do is to find what are the numbers GCF which in this case it is 8
which now with the GCF you divide -8 by 8 and 40 by 8
which -8 divided by 8 is -1
and 40 divided by 8 is 5
so the fraction is -[tex]\frac{1}{5}[/tex]
HELP PLEASE! 50 POINTS AND WILL MARK BRAINLIEST.
While on vacation, your family traveled 2660 miles in 7 days. Your average speed was 380 miles per day.
a. Find the independent and the dependent variables.
b. Write a linear function that models the distance that your family traveled each day.
c. Use the model to find the distance traveled after 1.5 days of travel
Answer:
see below
Step-by-step explanation:
a. The independent variable is the speed
The dependent variable is the number of miles traveled because it depends on your speed
b. miles = s *day
miles = 380 * days
c. miles = 380 * 1.5
=570 miles
if a line has a slope of 2/3 a line that is perpendicular has a slope of what
Answer: -3/2
Step-by-step explanation:
The slope of this line is 2/3, so the slope of the line perpendicular will have the opposite reciprocal as a slope, which is -3/2.
10 POINTS PLEASE HELP ASAP!!! What is the length of the altitude of the equilateral triangle below?
Step-by-step explanation:
Hey there!
Looking on figure we find that triangle ABC is a Right angled triangle.
Taking reference angle as C, we get;
Perpendicular (p) = a
Base(b) = 5
And hypotenuse (h)= 10
Now;
Using Pythagoras relation, we get;
[tex]p = \sqrt{ {h}^{2} - {b}^{2} } [/tex]
Put all values.
[tex]a = \sqrt{ {10}^{2} - {5}^{2} } [/tex]
[tex]a = \sqrt{100 - 25} [/tex]
[tex]a = \sqrt{75} [/tex]
[tex]a = 5 \sqrt{3} [/tex]
Therefore, answer is Option E.
Hope it helps..
