Tom made $171 for 9 hours of work. At the same rate, how many hours would he have to work to make 323 ?
Answer:
Your answer would be 17 because 171 divided by 9 is 19, so 323 divided by 19 would be 17.
Answer:
17 hoursStep-by-step explanation:
Tom made $171 for 9 hours of work. At the same rate, how many hours would he have to work to make 323 ?
we can solve with an equation171 : 9 = 323 : x
x = 9 * 323 : 171
x = 2907 : 171
x = 17

The y circle contains the numbers 2, negative 2, and 1. Arrows map numbers from x to numbers from y. There are arrows going from 6 to negative 2, from negative 2 to 2, from 4 to 1, and from negative 1 to 1. Yes, because each output value has only one input value Yes because each input value has only one output value No, because there is an input value with more than one output value No, because there is an output value with more than one input value
each input is mapped into only one output, so this is in fact a function.
Is the following relation a function?A relation is a function if and only if each input is mapped into only one output.
Remember that an ordered pair is of the form (x, y), where x is the input and y the output.

solve these simultaneous equations
2x+3y=13
and 4x+6y=26
Answer:
2x + 3y = 13
4x - y = -2
In the second equation, subtract 4x from both sides.
-y = -2 - 4x
Divide both sides by -1.
y = 2 + 4x
Put this into the first equation in place of y.
2x + 3(2 + 4x) = 13
Multiply everything in the parenthesis by 3.
2x + 6 + 12x = 13
Combine like terms.
14x + 6 = 13
Subtract 6 from both sides.
14x = 7
Divide 14 on both sides.
x = 7 / 14
x = 0.5
Put this into the second equation in place of x.
4(0.5) - y = -2
2 - y = -2
Subtract 2 from both sides.
-y = -4
Divide both sides by -1.
y = 4
So x = 0.5 and y = 4.

A parabola opening up or down has vertex (0, 1) and passes through (12, -17). Write its
equation in vertex form.
Simplify any fractions.
The equation of the parabola is y = (-3/2)x + 1.
The general vertex form of the equation of a parabola is y = a(x - h)2 + k
where (h, k) are the coordinates of the vertex
Here, we are given that vertex = (0, 1)
Thus, the equation of the parabola is-
y = a(x - 0)2 + 1
y = 2ax + 1
Also, we are given that the parabola passes through (12, -17).
Thus, (12, -17) must satisfy the equation of the parabola
⇒ -17 = 2a(12) + 1
-17 = 24a + 1
24a = -17 -1
24a = -18
a = -18/24
a = -3/4
Thus, the equation of the parabola becomes-
y = 2(-3/4)x + 1
y = (-3/2)x + 1

Solution of the equation [tex][\frac{1}{5(10x-5)} =(5x-1)][/tex] is [x = (-0.512788205961), (-0.187211794039)].
As per the question statement, our concerned equation is [tex][\frac{1}{5(10x-5)} =(5x-1)][/tex].
We are required to find the value of "x" that satisfied the equation. First, we will have to convert the given equation to the form of quadratic equation.
[tex][\frac{1}{5(10x-5)} =(5x-1)]\\or, 1=5(10x-5)*(5x-1)\\or, 1=5*5(2x-1)*(5x-1)\\or,1=25[(2x-1)(5x-1)]\\or,1=25(10x^{2} -2x-5x+1)\\or,1=25(10x^{2} -7x+1)\\or,1=250x^{2} -175x+25\\or,250x^{2} -175x+24=0\\[/tex]
Now, [(250x² - 175x + 24) = 0] is in the form of a quadratic equation.
Also, the formula to calculate the solutions of a standard quadratic equation [ax² + bx +c = 0] goes as [tex][x=(\frac{-b+\sqrt{(b^{2}-4ac) } }{2a}), (\frac{-b-\sqrt{(b^{2}-4ac) } }{2a}) ][/tex]
Comparing [ax² + bx +c = 0] with [(250x² - 175x + 24) = 0], we get
(a = 250), (b = 175) and (c = 24), and using these values in the above mentioned formula to calculate the solutions of quadratic equations, we get, [x = (-0.512788205961), (-0.187211794039)].

How to determine the solution to the inequality?The given parameters are:
Perimeter < 18.7 feet
Side lengths: 4.1 ft 4.9 ft 6.4 ft x ft
The perimeter of a shape is the sum of the side lengths
So, we have
Perimeter = 4.1 ft + 4.9 ft + 6.4 ft + x ft
Remove the unit
So, we have
Perimeter = 4.1+ 4.9 + 6.4 + x
Evaluate the sum
Perimeter = 15.4 + x
Recall that
Perimeter < 18.7 feet
So, we have
15.4 + x < 18.7
Subtract 15.4 from both sides
x < 3.3

As t increases the curve is changing according to the plot points given by the parametric equations.
Define parametric equations?The coordinates of the points that make up a geometric object, such as a curve or surface, are frequently expressed using parametric equations; in this case, the equations are collectively referred to as a parametric representation or parameterization (alternatively spelled as parametrisation) of the object. It describes a collection of numbers that represent functions with one or more independent variables. The parameters used here are the independent variables. For the representation of the coordinates that make up geometric objects like curves and surfaces, parametric equations are used.

Type A car has the highest number of miles per gallon.
Given that the miles driven by a Type A car is 106 miles for 5 Gallons of Gasoline.
⇒ miles per gallon for a Type A car = 106/5 = 21.2 miles/gallon
Given that the miles driven by a Type B car are 204 miles for 10 Gallons of Gasoline.
⇒ miles per gallon for a Type B car = 204/10 = 20.4 miles/gallon
Given that the miles driven by a Type C car are 298 miles for 15 Gallons of Gasoline.
⇒ miles per gallon for a Type A car = 298/15 = 19.87 miles/gallon
(approximate to the two places of decimal value)
Given that the miles driven by Type D car are 392 miles for 20 Gallons of Gasoline.
⇒ miles per gallon for a Type D car = 392/20 = 19.6 miles/gallon

Answer:
Equation is 15(x-20) = 945
x = $83
Step-by-step explanation:
The cost of each lesson is $x
The discounted cost = x-20
Since 15 lessons cost 945,
the equation is
15(x-20) = 945
Simplifying by multiplying the term in brackets by 15:
15x - 15(20) = 945
15x - 300 = 945
Adding 300 on both sides isolates the 15 x term
15x = 945 + 300 = 1245
15x = 1245
Dividing both sides by 15 ,
x = 1245/15 = 83
So cost of lesson before discount is $83
