What properties can be used to solve 7y-15=-29. Identity property of multiplication,addition property of equality ,distributive property,inverse property of mulplication,commutative property of addition
Answer:
Addition Property of Equality.
Inverse property of multiplication.
Step-by-step explanation:
Given the equation:
[tex]7y-15=-29[/tex]
First of all, let us use Addition Property of Equality.
According to the property, if we add a number on both sides of an equality, there is no change in the equality.
In other words, the equality will be same if we add the same number on Left Hand Side and Right Hand Side of the equality.
First of all, let us add 15 on both sides of the equality:
[tex]7y-15+15=-29+15\\\Rightarrow 7y=-14[/tex]
Now, let us Inverse property of multiplication.
i.e. Multiplication of a number with its inverse is equal to 1.
[tex]a\times \frac{1}{a} = 1[/tex]
So, let us multiply the given equation with [tex]\frac{1}7[/tex]
[tex]7y \times \dfrac{1}{7}=-14 \times \dfrac{1}{7}\\\Rightarrow 1y =-2\\\Rightarrow y=-2[/tex]
The properties used are:
Addition Property of Equality.
Inverse property of multiplication.
Solve the equation for X.
4+2(x-4)=-7(x+7)
x=5.9
x=-5
x=5
x=-7.4
Answer:
x = -5
Step-by-step explanation:
4 + 2(x - 4)= -7(x + 7)
4 + 2x - 8 = -7x - 49
2x - 4 = -7x - 49
2x + 7x = -49 + 4
9x = -45
x = -45/9
x = -5

Find the point-slope equation for
the line that passes through the
points (1,-9) and (-10, 101). Use
the first point in your equation.
y + 9 = [ ? ](x-[ ])
Answer:
Below in bold.
Step-by-step explanation:
The slope of the line = (101 - -9) / (-10 - 1)
= 110/ -11
= -10
The required equation is y + 9 = -10(x - 1)
Write the phrase as an expression.
the difference of a number t and 9
Answer:
[tex] t - 9 [/tex]
Step-by-step explanation:
Given that t represents a number which is unknown to us, the difference of the number and 9 can be expressed algebraically as:
[tex] t - 9 [/tex].
The difference of t and 9 = [tex] t - 9 [/tex].
When should you use the distributive property?
The distributive property is used when you have a value multiplied by 2 values separated by an operation.
For example, if you have x (y + z), then you would use the distributive property to get x (y + z) = xy + xz.
solve for x 1/4(4x-1)=-1/7-5/7
Answer:
[tex]x=-\frac{17}{28}[/tex]
Step-by-step explanation:
[tex]\frac{1}{4}(4x-1)=-\frac{1}{7}-\frac{5}{7}[/tex]
[tex]x-\frac{1}{4}=-\frac{6}{7}[/tex]
[tex]x = -\frac{6}{7} + \frac{1}{4}[/tex]
[tex]x = -\frac{17}{28}[/tex]
plug [tex]x[/tex] in the equation to make sure of your answer:
[tex]\frac{1}{4}(4x-1)=-\frac{1}{7}-\frac{5}{7}\\\frac{1}{4}(4(-\frac{17}{28}) -1)=-\frac{1}{7}-\frac{5}{7}\\-\frac{17}{28} -\frac{1}{4}=-\frac{6}{7}\\-\frac{6}{7}=-\frac{6}{7}[/tex]

What simple interest rate would allow $6000 to grow to an amount of $14550 in 10 years?
Answer:
[tex] \boxed{ \bold{ \huge{ \boxed{ \sf{ \: 14.25 \: \% \: }}}}}[/tex]
Step-by-step explanation:
Given,
Principal ( P ) = $ 6000
Amount ( A ) = $ 14550
Time ( T ) = 10 years
Rate ( R ) = ?
Finding the Interest
The sum of principal and interest is called an amount.
From the definition,
[tex] \boxed{ \sf{Amount = \: Principal + Interest}}[/tex]
plug the values
⇒[tex] \sf{14550 = 6000 + Interest}[/tex]
Swap the sides of the equation
⇒[tex] \sf{6000 + Interest = 14550}[/tex]
Move 6000 to right hand side and change its sign
⇒[tex] \sf{Interest = 14550 - 6000}[/tex]
Subtract 6000 from 14550
⇒[tex] \sf{Interest = \: 8550 \: }[/tex]
Interest = $ 8550
Finding the rate
[tex] { \boxed{ \sf{Rate = \frac{Interest \times 100}{Principal \times Time}}}} [/tex]
plug the values
⇒[tex] \sf{ Rate = \frac{8550 \times 100}{6000 \times 10} }[/tex]
Calculate
⇒[tex] \sf{Rate = \frac{855000}{60000} }[/tex]
⇒[tex] \sf{Rate = 14.25 \: \% \: }[/tex]

If you only have a compass and straightedge, how would you construct an equilateral triangle so segment AB is one of the sides?
Describe the steps, be very specific.
A
•B
Need help ASAP
Answer:
Step-by-step explanation:
To construct an equilateral triangle so that segment AB is one of the sides of the triangle we will follow the following steps.
1). Set a distance equal to the segment AB in the compass and draw two arcs on the same side of AB.
2). Join the point of intersection of these arcs to A and B with the help of a straightedge.
3). Hence an equilateral triangle (with all equal sides) is constructed.

Which figure represents an undefined term?
Answer: 4th figure , where XY is a line.
Step-by-step explanation:
There are 3 undefined terms : 1) point 2) line 3 ) planeFrom up to down, The first figure is representing ray( end point at X ) which is an defined term and it is defined as "A ray is a line with one end point."
The second figure is representing a line segment with 2 end-points at X and Y and it is and defined term and it is defined as "A line segment is a line with 2 end points."
The third figure is a joint of two rays and they are making an angle which is again an defined term.
The last figure is representing a line which has no endpoints and is an undefined term.
Hence, the last figure is representing an undefined term "line".

Answer:
The answer is A, 19/49
Step-by-step explanation:
normally you would do the equation as usual, but if you notice the words (without replacing the first) then that means there will be 24 marbles left.
that means it can't be B C or D because 24 can't be simplified into the denominators 5, 20, or 15

Point Coordinate
A 0.31
B 0.33
C 0.38
D 0.29
Which number line shows the correct placement of the points in the table above?
A
B
C
D
Step 1:
First, let's order the number from least to greatest.
A. -0.31
B. -0.33
C. -0.38
D. -0.29
We could see that A, B, and C's numbers are already from least to greatest, so all we have to do is to move -0.29 (D) up to the top, since -0.29 is the number with the lowest value.
C. -0.38
B. -0.33
A. -0.31
D. -0.29
Step 2:
Let's look at the four number lines. Remember that we already organized the numbers from least to greatest, so the order they go in on the number line is: C, B, A, and D. Since Line C and D Don't follow that rule, we know those are not our answers. Also on line B, C is on the left of -0.4, but C's value is less than -0.4, so B is wrong. We are left with line A.
Line A: C. -0.38, B. -0.33, A. -0.31, D. -0.29
Our answer: Line A
Answer:
B: -0.3
