Answer:
[tex]x=-\frac{11}{18}[/tex]
Step-by-step explanation:
[tex]-1\frac{7}{9}=(-2\frac{5}{6} + \frac{1}{3})x[/tex]
Solve parenthesis first
[tex]-2\frac{5}{6} + 1/3[/tex]
Find a common denominator.
The common denominator would be 6.
Because the first expression already has a denominator of 6 it stays the same.
[tex]\frac{1}{3} = \frac{2}{6}[/tex]
[tex]-2\frac{5}{6} + \frac{2}{6} = -2\frac{7}{6} = -1\frac{1}{6}[/tex]
Put that into the original equation.
[tex]-1\frac{7}{9}=(-1\frac{1}{6} )x[/tex]
Isolate the x. Add [tex]1\frac{1}{6}[/tex] to each side.
[tex]-1\frac{7}{9}+ 1\frac{1}{6}=x[/tex]
Find a common denominator.
we can use 18 as the common denominator.
[tex]-1\frac{7}{9}+ 1\frac{1}{6}= -1 \frac{14}{18} +1\frac{3}{18}= x[/tex]
Add.
[tex]-\frac{11}{18} =x[/tex]
We cannot simplify so our answer stays the same.

Setup a proportion to answer the problem.
$27.50

1.50 * 3 = 4.5 (cost 1 pound)
4.5 * 5 = 22.5 (total cost)
The cost of 5 pounds of beef for a cookout given the cost of 1/3 pounds is $22.50
How to find the cost of beef1/3 pounds = $1.505 pounds = $xEquate the ratio
1/3 : 1.50 = 5 : x
1/3 ÷ 1.50 = 5/x
1/3 × 1/1.50 = 5/x

find (f-g)(x) for f(x)=x^2+8x and g(x)=3x-5
Answers
Answer:
(f-g)(x)= f(x) - g(x)
= x^2 + 8x - ( 3x - 5)
= x^2 + 8x - 3x + 5
= x^2 + 5x + 5
(f-g)(x)= x^2 + 5x + 5
The required expression of (f-g)(x) = x^2+5x+5.
f(x) = X^2+8x; g(x) = 3x - 5
(f-g)(x) to determine.
It is defined as the number of composition, constitute the whole.
Here, (f-g)(x)= f(x)-g(x)
= x^2+8x-3x+5
= x^2 + 5x + 5
Thus, the required expression of (f-g)(x) = x^2+5x+5.

State if each triangle is a right triangle.
Answers
Answer:
Yes.
Step-by-step explanation:
To find if a triangle is a right triangle or not, we use the Pythagorean theorem. The Pythagorean theorem states that [tex]a^{2} + b^{2} = c^{2}[/tex].
a and b are the triangle legs. The c is the hypotenuse of the triangle.
Now, to find if a triangle is a right triangle, we plug in 9 for a and b and 9root2 for c.
[tex]9^{2} + 9^{2} = (9\sqrt{2})^{2}[/tex]
81 + 81 = 81 * 2
162 = 162
So the given triangle, is indeed a right triangle.

Let 1995 correspond to x=0. Let b be the ratio between the population in 1995 and 1996. Determine an exponential function of the form y=a(b)^x to represent the population symbolically. Round to 3 decimal places.
Answers
The table is an illustration of an exponential function
The equation of the table is [tex]y = 148 * 0.997^x[/tex]
How to determine the equation of the tableGiven that 1995 corresponds to x = 0, then
The initial value (a) of the function is:
a = 148.0
The equation of the function is:
[tex]y = ab^x[/tex]
When x= 1, we have:
[tex]147.6 = ab^1[/tex]
[tex]147.6 = ab[/tex]
This gives
[tex]147.6 = 148b[/tex]
Divide both sides by 148
[tex]b = 0.997[/tex]
Hence, the equation of the table is:
[tex]y = 148 * 0.997^x[/tex]

What is the average speed of a car that travels 440 km in 15.4 hours?
Answers
A car travels 440km in 15.4 hours -> In 1 hour, the car travel 1/(15.4) the distance.
So in an hour, the car travel : 440 x 1/(15.4) = 28.5714285714... (round to 29)

-The dimensions of a rectangular garden were 2 m by 4 m. Each dimension was
Increased by the same amount. The garden then had an area of 48 m2. Find the
dimensions of the new garden. (Hint: let x be the amount of increase.)
Answers
Answer: 4 m
Step-by-step explanation:
Let the amount each dimension was increased by be x.
Now we can set up a equation.
(2+x)(4+x) = 48
8 + 2x + 4x + x^2 = 48
x^2 + 6x - 40 = 0.
We can factor the left side of the equation.
(x+10)(x-4) = 0.
Therefore, x equals either -10 or 4. Since you can't increase a dimension by a negative amount, x must equal to 4.
Answer:The new garden is 7m by 8m.
