Answer:
doing the inverse operationStep-by-step explanation:
You can tell how to isolate a variable by listing the operations done to it, as prescribed by the order of operations. Then, you work backwards up the list performing inverse operations as you go.
__
Additional comment
Where mixed powers of the variable are involved, as in polynomials of degree higher than 1, there is generally not an inverse operation you can use to isolate the variable. Rather, special forms are used that facilitate isolating the variable. The variable in a quadratic, for example, can be isolated by "completing the square." Similar procedures are available for solving cubic and quartic equations, though those tend to be somewhat more complicated.
There are many kinds of equations in which there are no methods for isolating the variable. In general, any mix of polynomial terms and logarithmic, exponential, or trigonometric function terms are in that category: x +sin(x) -3 = 0, for example. (A graphing calculator shows the solution is near x=2.18, where the angle is in radians.)

Beatrice traveled the last 220 miles of the trip at 55 miles per hour. The entire trip
covered 430 miles and took 7 hours. What was her rate for the first 210 miles?
Answer:
Beatrice traveled the last 220 miles of the trip at 55 miles per hour. The entire trip covered 430 miles and took 7 hours. What was her rate for the first 210 mile?
Let Beatrice's average speed for the first 210 miles = S
220/55 + 210/S
Solve for S:
4 + 210/S = 7
Bring 4 + 210/S together using the common denominator S:
(2 (2 S + 105))/S = 7
Multiply both sides by S:
2 (2 S + 105) = 7 S
Expand out terms of the left hand side:
4 S + 210 = 7 S
Subtract 7 S + 210 from both sides:
-3 S = -210
Divide both sides by -3:
Answer: |S = 70 - miles per hour, her speed for the first 210 mStep-by-step explanation:

In what ratio is the line joining the points.
(-1,8) and (5,2) divided by the point (3,4)
Answer:
2:1
Step-by-step explanation:
use k:1 as ratio, and then apply the section formula.
let's use the x co-ordinate pf the point in between the other two which is=(3)
section formula says,
x=mx2 + nx1/(m+n)
m=k , n=1
substitute all the values,
3=5k+(-1)/(k+1)
take k+1 to left side,
3(k+1)=5k-1
3k+3=5k-1
5k-3k=3+1
2k=4
(÷2)
k=2
hence, the ratio = 2:1
x²+x-56=0 quadratic equations
Step-by-step explanation:
To solve the equation, factor x
2
+x−56 using formula x
2
+(a+b)x+ab=(x+a)(x+b). To find a and b, set up a system to be solved.
a+b=1
ab=−56
Since ab is negative, a and b have the opposite signs. Since a+b is positive, the positive number has greater absolute value than the negative. List all such integer pairs that give product −56.
−1,56
−2,28
−4,14
−7,8
Calculate the sum for each pair
−1+56=55
−2+28=26
−4+14=10
−7+8=1
The solution is the pair that gives sum 1.
a=−7
b=8
Rewrite factored expression (x+a)(x+b) using the obtained values.
(x−7)(x+8)
To find equation solutions, solve x−7=0 and x+8=0.
x=7

_____=_____
Answer:
[tex]131=6w[/tex]
Step-by-step explanation:
[tex]l=length\\\\w=width\\\\\Longrightarrow l=2w\\\\\Rightarrow Perimeter=l+l+w+w\\\\P=2l+2w\\\\P=2(2w)+2w\\\\P=4w+2w\\\\P=6w\\\\P=131\\\\131=6w\\\\w=\frac{131}{6}\\\\w=21.8\overline{3}\\\\l=43.\overline{6}[/tex]
Answer:
A) l = 2 * w
B) 131 = 2l + 2w
B) 2l = 131 -2w
B) l = 65.5 -w
Substituting this into A)
65.5 -w = 2w
3w = 65.5
width = 21.8333333333
length = 43.6666666666
Double - Check
131 = 2 * 21.833333333 + 2 * 43.6666666666
131 = 43.6666666 + 87.33333333

An emperor penguin dives down into the ocean at a constant rate. From the surface, he dives 1,760 feet in 8 minutes. The number -1760 represents the location of the penguin in relation to the surface. What number represents the location of the penguin in relation to the surface 2 minutes after beginning his dive?
Answer:
location after 2 minutes dive from the surface = -440 feet
Step-by-step explanation:
We are told that he dives 1,760 feet in 8 minutes.
Now, we are told that he dives down at a constant rate.
Thus means that the distance he dives per minute can be gotten.
Distance dived per minute = 1760/8 = 220 feet/minutes
Now, we want to find the location of the penguin in relation to the surface 2 minutes after beginning his dive.
Thus;
Distance after 2 minutes = 220 feet/minutes × 2 minutes = 440 feet
Now, because the dive is below the surface, the location will be negative.
Thus, location after 2 minutes dive from the surface = -440 feet

Answer:
Less Than
Step-by-step explanation:
Given;
The equation of one exponential function is
[tex]g(x)=-9(0.1)^x[/tex]
Solve for (y-intercept of g(x))
⇒ [tex]g(x) = -9(0.1)^x[/tex]
⇒ [tex]y = -9(0.1)^0[/tex]
⇒ [tex]y = -9[/tex]
Note;
The y-intercept is when x = 0
y-intercept of h(x) = 6
Hence, knowing that -9 < 6.
Thus, y-intercept of g(x) is less than the y-intercept of h(x).
~Learn with lenvy~
Answer:
less than
Step-by-step explanation:
The y-intercept is when x = 0
Function g(x)
[tex]g(x)=-9(0.1)^x[/tex]
Input x = 0 into the equation and solve:
[tex]\implies g(0)=-9(0.1)^0=-9[/tex]
Therefore, the y-intercept of g(x) is (0, -9)
Function h(x)
From inspection of the table, the y-intercept of h(x) is (0, 6)
As -9 < 6, the y-coordinate of the y-intercept of g(x) is less than the y-coordinate of the y-intercept of h(x)

Sam's Club has a special that charges $2.49 per case of water. Vinny wants to pay that price, but needs to purchase a membership first, which costs $50. If Vinny spent $67.43, which equation represents how many cases of water Vinny bought at Sam's club?
Answer: $50 + $2.49x = $67.43
Step-by-step explanation:
Let the case of water bought be represented by x.
We are informed that Sam's Club has a special that charges $2.49 per case of water and that Vinny wants to pay that price, but needs to purchase a membership first, which costs $50 and that Vinny eventually spent $67.43.
The equation that represents the number of cases of water that Vinny bought at Sam's club will be:
$50 + $2.49x = $67.43
Which graph represents the inequality 3y−5x>−6?
Answer:Top Left
Step-by-step explanation:
Graph A represents the given inequality 3y−5x>−6. Option A is correct.
From the graphs, the graph is to choose which best describes the inequality 3y−5x>−6
What is inequality?Inequality can be defined as the relation of an equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.
Given inequality,
3y−5x>−6.
Since the inequality contains only greater than sign, so options B and C will be omitted because both the graphs show boundary conditions that are wrong for the given inequality.
Now, graph A and D show now boundary condition and shaded portions
3y−5x>−6
Since the inequality is shown greater than -6 so the inequality will start from a negative y toward the positive y i.e.
3y−5x > −6
3y > 5x - 6
y > (5x - 6)/3
The above expression shows the value of y lies above the line y =5x/3-2 which implies graph A is correct.
Thus, Graph A represents the given inequality 3y−5x>−6. Option A is correct.
