[tex] \implies \sf{x = 2 \times 15}[/tex]
[tex] \implies \sf{x = 30}[/tex]
Answer:
x=30
Step-by-step explanation:
3/5x+2=2/3x
So for solving for x you are going to first try to get x on the same side so move 2/3x to the left side of the equal sign. so it becomes 3/5x-2/3x+2=0 then you are going to combine like terms and subtract 2/3x from 3/5x so it becomes 9/15x-10/15x since they have least common denominater which is 15 so it becomes 9/15 and 10/15 then you subtract them so it is -1/15x+2=0 then you are going to move the 2 to the other side of the equal sign so it is -1/15x=-2 then you are going to divide multiply -15 to both sides to get rid of it from the x side so you can isolate it so therefore the answer is x=30

Answer:
0, 1, and 4
Step-by-step explanation:
Since the denominator of a fraction must not be 0 or it would be undefined, when the denominator is 0 is where you will find your restrictions:
[tex]x^3-5x^2+4x=0 \\\\x(x^2-5x+4)=0 \\\\x(x-1)(x-4)=0[/tex]
Therefore, by the zero product property, the restrictions are 0, 1, and 4. Hope this helps!
Answer:
X cannot equal 0,1,4
Step-by-step explanation:
The restrictions are when the denominator goes to zero
x^3 -5x^2 +4x
Factor an x
x( x^2 -5x+4)
x( x-4) (x-1)
Set each term to zero
x=0 x-4 =0 x-1=0
x=0 x=4 x=1
X cannot equal 0,1,4

Triangle EFG is dilated by a scale factor of one half centered at (1, 1) to create triangle E'F'G'. Which statement is true about the dilation?
- The slope of segment EF is the same as the slope of segment E prime H prime.
- segment E prime G prime will overlap segment EG.
- segment GF and segment G prime F prime both pass through the center of dilation.
- segment EF ≅ segment E prime F prime.
Answer:
- segment GF and segment G prime F prime both pass through the center of dilation.
Step-by-step explanation:
The center of dilation (1, 1) is the same point that vertex F, then, both F and F' are located at (1, 1).
G is located at (-2, 1). After the dilation by a scale factor of one half, G' is located at (-0.5, 1), so that the distance between G' and F' is half the distance between G and F. Therefore, segment GF and segment G'F' both pass through the center of dilation.
Answer:
segment GF and segment G prime F prime both pass through the center of dilation.

A number cube with the numbers 1 through 6 is rolled. What is the theoretical probability, as a decimal, of the number cube showing a 1? Round the decimal to the nearest hundredth.
Answer:
The probability of the number cube showing a 3 = 0.1667
Step-by-step explanation:
A number cube with the numbers 1 through 6 is rolled.
So, The numbers which are marked on the cube : 1, 2, 3, 4, 5, 6
Total no. of numbers which are marked on the number cube = 6
No. of times the number cube is rolled = 1
We need to find the theoretical probability, as a decimal, of the number cube showing a 3.
Therefore, The probability of the number cube showing a 3 is given by :

Solve for x in the diagram below.
(2x + 30°
40°
40°
т
Answer:
x = 35°
Step-by-step explanation:
assuming that the straight line at the bottom of the figure is actually a straight line, that means all the angles along that straight line must add up to 180 °
i.e.
40 + (2x+30) + 40 = 180
40 + 2x+30 + 40 = 180
110 + 2x = 180 (subtract 110 from both sides)
2x = 180 - 110
2x = 70
x = 35
Answer:
x=35
Step-by-step explanation:
The 3 angles are on a straight line. A straight line is equal to 180 degrees. Therefore, the 3 angles are supplementary and add to 180 degrees.
40+2x+30+40=180
Combine like terms. Add all the terms on the left side without a variable.
2x+(40+30+40)=180
2x+110=180
We want to find out what n is. In order to do this, we have to get n by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.
110 is being added to 2x. The opposite of addition is subtraction. Subtract 110 from both sides.
2x+110=180-110
2x=180-110
2x=70
x is being multiplied by 2. The opposite of multiplication is division. Divide both sides by 2.
2x/2=70/2
x=70/2

Three functions are given below: f(x), g(x), and h(x). Explain how to find the axis of symmetry for each function, and rank the functions based on their axis of symmetry (from smallest to largest).
Answer:
three functions are
f(x) = 3(x + 4)^2 + 1
g(x) = 2x^2 - 16x + 15
h(x) = a(x - 1) - 3
Axis of symmetry for f(x) is x=-4 For g(x)
by taking the derivative
g'(x) = 4x - 16
= 4(x - 4)
The Axis of symmetry for g(x) is x=4
The Axis of symmetry for h(x) is x=1

A line passes through (-5, -3) and is parallel to -3x - 7y= 10. The equation of the line in slope-intercept form is
Y=-3/7x-36/7
Y=-3/7x-6/7
Y=-7/3x-36/7
Y=-7/3x-6/7
Answer:
A.
Step-by-step explanation:
-3x-7y = 10
In slope - intercept form
y = -3/7x - 10/7
Since the lines are parallel so the slopes will be equal
m = -3/7
Now
Point = (x,y) = (-5,-3)
So, x = -5, y = -3
Putting in slope intercept form to find b
y = mx+b
-3 = (-3/7)(-5) + b
-3 = 15/7 + b
7b = -21-15
7b = -36
b = -36/7
Now the slope intercept form for the line is
y = -3/7x-36/7
Write each statement as an algebraic expression. The quotient of the number that is 1 greater than a number b and the number that is twice as large as b. RMS NEED BY 3:58 today 6/20/2020
Answer:
Quotient = (1 + b)/2b
Step-by-step explanation:
The term quotient implies the result after dividing a number or expression by another number or expression.
In other words,
Quotient = Dividend/Divisor
From the question, we understand that
Dividend = Number that is 1 greater than a number b
So,
Dividend = 1 + b
And
Divisor = Number that is twice as large as b...
So, Divisor = 2 * b
Divisor = 2b
Recall that:
Quotient = Dividend / Divisor
Quotient = (1 + b)/2b

Use additive inverses and their properties to find the equivalent expressions.
Answer:
Equivalent expression:
a) -9
b) 3
c) 9
d) -3
Step-by-step explanation:
The Property of Additive Inverse states that the summation of a number and it's Additive inverse = 0
An Additive inverse of a positive integer is a negative integer and vice versa.
For example:
5 -5 = 0
The additive inverse of 5 = -5
For the question above, we are asked to use the additive inverses and their properties to find the equivalent expressions.
a) 6 -(-3)
Additive inverse = - 6 + (-3)
= -6 - 3 = - 9
b) -6 -3
Additive inverse = 6 +(-3)
= 6 - 3 = 3
c) 6 - 3
Additive inverse = 6 + 3
= 9
d) -6 - (-3)
Additive inverse = -6 + 3
= -3

On a coordinate plane, triangle A B C is shifted 4 units to the right and 2 units up to form triangle A prime B prime C prime. Identify the rule for the transformation shown in the figure that translates triangle ABC into triangle A'B'C'. (x, y) Right-arrow (x – 4, y – 2) (x, y) Right-arrow (x + 4, y – 2) (x, y) Right-arrow (x – 4, y + 2) (x, y) Right-arrow (x + 4, y + 2)
Answer:
(x, y) ⟶ (x + 4, y + 2)
Step-by-step explanation:
If you shift a point four units to the right, x ⟶ x + 4.
If you shift it up two units, y ⟶ y + 2.
If you combine the two shifts into one transformation, the rule becomes
(x, y) ⟶ (x + 4, y + 2)
