Step-by-step explanation:
Set g(x)=y
y=-2/5x+3
5y=-2x+3
2x=3-5y
x=3-5y/2
So g^-1(x)=

Find the perimeter. Simplify your answer.
Answers
Answer:
6z-30 :D
Step-by-step explanation:
Step-by-step explanation:
The perimeter of a square is just all the sides added up together. To do this we can make an equation.
2(z-5) + 2(2z - 10)
This represents two sides with different lengths two times. To solve, you first use the distributive property to multiply z-5 by 2.
2z - 10 + 2(2z - 10)
We then use the distributive property by multiplying 2z - 10 by 2.
2z − 10 + 4z − 20
We then combine 2z and 4z to get 6z.
6z − 10 − 20
Subtract 20 from 10 to get -30.
6z-30.
Why rectangular coordinates are better than polar.
Answers
Answer:
Rectangular coordinates, or cartesian coordinates, come in the form (x,y).. Polar coordinates, on the other hand, come in the form (r,θ). Instead of moving out from the origin using horizontal and vertical lines, we instead pick the angle θ, which is the direction, and then move out from the origin a certain distance r.

A staff gauge measures the height of the water level in a river compared to the average water level. At one gauge the river is 1 ft below its average water level of 10 ft. It begins to rise by a constant rate of 1.5 ft per hour.
Will the river reach a level of 7 ft above normal after 5 hours? Explain.
Answers
The river will not reach a level of 7 ft. after 5 hours.
A linear equation is in the form:
y = mx + b
where y, x are variables, m is the rate of change and b is the initial value of y.
Let y represent the height of the water level after x hours.
Since the river is 1 ft below its average water level and begins to rise by a constant rate of 1.5 ft per hour. Hence:
b = -1, m = 1.5. The equation becomes:
y = 1.5x - 1
To reach a level of 7 ft. That is y = 7:
7 = 1.5x - 1
1.5x = 8
x = 5.3 hours
The river will not reach a level of 7 ft. after 5 hours.

Answer:
6.5, will not
Step-by-step explanation:
The water level is 6.5 ft above normal after 5 hours, so it

Make x the subject of the formula:
t=w+(q/x)
Answers
Answer:
q
-------- = x
t - w
Step-by-step explanation:
Isolate (q/x) on the right side of this equation, by subtracting w from both sides. Then:
t - w = q/x, or
t - w q
------- = -----
1 x
Next, invert this equation. We get
1 x
--------- = -----
t - w q
Finally, multiply both sides by q:

Answer:
Obtuse scalene triangle
Step-by-step explanation:
1. Angles:
-> Acute triangle: all angles less than 60° -> Right triangle: one angle is 90° -> Obtuse triangle: one angle is greater than 90°- Given the information above, we can see that the triangle has one angle that's greater than 90° (129°), so this triangle is obtuse.
2. Sides:
-> Scalene triangle: all sides have different lengths-> Isosceles triangle: two sides have same length-> Equilateral triangle: all sides are the same- Given the information above, we can see that all the sides in the triangle are different, so this triangle is scalene.
Therefore, the answer is an obtuse scalene triangle.

Rearrange the equation so y is the subject.
1. Add 8 to both sides
2y = 6x + 8
2. Divide both sides by 2
y = 3x + 4
Voilà, you got your answer in the line format, y = mx + c, where m is the slope and c is the y intercept.

5(6a +1) = 7(4x + 3) w/steps
Answers
Answer:
[tex]\frac{15a- 8}{14} = x[/tex]
Step-by-step explanation:
Step 1 - Divide both sides of the equation by 7:
[tex]5(6a + 1) = 7(4x + 3)\\[/tex]
[tex]\frac{5(6a + 1)}{7} = \frac{7(4x + 3)}{7} \\\\\frac{5(6a + 1)}{7} = 4x + 3[/tex]
Step 2 - Subtract 3 from both sides to isolate the 4x:
[tex]\frac{5(6a + 1)}{7} - 3 = 4x + 3 - 3\\\frac{5(6a + 1)}{7} - 3 = 4x[/tex]
Step 3 - Expand equation:
[tex]\frac{5(6a + 1)}{7} - 3 = 4x \\\\\frac{30a + 5}{7} - 3 = 4x[/tex]
Step 4 - Translate -3 into a fraction and add it:
[tex]\frac{30a + 5)}{7} - 3 = 4x\\\frac{30a + 5 + (7 * -3)}{7} = 4x\\\frac{30a + 5 + (-21)}{7} = 4x\\[/tex]
[tex]\frac{30a - 16}{7} = 4x[/tex]
Step 5 - Divide both sides of the equation by 4:
[tex]\frac{\frac{30a - 16}{7}}{4} = \frac{4x}{4}[/tex]
Multiply the two fractions together to simplify:
[tex]\frac{30a - 16}{4 * 7} = \frac{4x}{4}[/tex]
[tex]\frac{30a - 16}{28} = x[/tex]
Step 6 - Simplify by dividing the fraction by 2:
[tex]\frac{(30a \div 2)- ( 16 \div 2)}{28 \div 2} = x[/tex]
[tex]\frac{15a- 8}{14} = x[/tex]
