Answer:
7+(x+5) (original equation)
x+12 (simplified)
Step-by-step explanation:
So we know the number is x
Since its just an expression we can’t make x equal to anything so the best we can do is simplify the expression given.
so 7 plus the sum of x and 5
7+(X+5)
Mow just simplify it
x+5 is x+5
x+5+7 is 12+x becuase 5+7 is 12 and I combined like terms
x+12
Answer:
Expression: 7+x+5
Simplified: 12+x

Please help out, what is the slope here? This question is worth 20 points
Answer:
the slope is 1
you find two points that are directly on an intersection of the grid. and then count rise/run
rise is going up and down and run is left and right
start at the point you found furthest to the left and count to the next point that's to the right.
if you have to go down to find it or left to find it, the slope is negative
in this case. theres a point at (-1,0) and (0,1)
you have to count up one and right one, making the slope 1/1 or simplified to 1

factories 54m3n + 81m4n2 b) 15x2y3z + 25x3y2z + 35x2y2z
Part a)
Given the expression
[tex]54m^3n\:+\:81m^4n^2[/tex]
Apply exponent rule: [tex]a^{b+c}=a^ba^c[/tex]
[tex]54m^3n\:+\:81m^4n^2=54m^3n+81m^3mnn[/tex] ∵ [tex]m^4n^2=m^3mnn[/tex]
Rewrite 81 as 3 · 27
Rewrite 54 as 2 · 27
[tex]=2\cdot \:27m^3n+3\cdot \:27m^3mnn[/tex]
Factor out the common term: 27m³n
[tex]=27m^3n\left(2+3mn\right)[/tex]
Therefore,
[tex]54m^3n\:+\:81m^4n^2=54m^3n+81m^3mnn=27m^3n\left(2+3mn\right)[/tex]
Part B)
Given the expression
[tex]15x^2y^3z+25x^3y^2z+35x^2y^2z[/tex]
Apply exponent rule: [tex]a^{b+c}=a^ba^c[/tex]
[tex]15x^2y^3z+25x^3y^2z+35x^2y^2z=15x^2y^2yz+25x^2xy^2z+35x^2y^2z[/tex]
Rewrite as
[tex]=3\cdot \:5y^2x^2zy+5\cdot \:5y^2x^2zx+7\cdot \:5y^2x^2z[/tex]
Factor out common term 5y²x²z
[tex]=5y^2x^2z\left(3y+5x+7\right)[/tex]
Therefore,
[tex]15x^2y^3z+25x^3y^2z+35x^2y^2z=5y^2x^2z\left(3y+5x+7\right)[/tex]
The cost of manufactured goods is rising at the rate of inflation, or at about 2.3% 2.3 % . Suppose an item costs $12 $ 12 today. How much will it cost five years from now due to inflation? Round the answer to the hundredth.
Answer: $13.44
Step-by-step explanation:
Inflation is causing the manufactured goods to rise at 2.3% per year. The price in 5 years can be calculated using compound interest formula:
= 12 * ( 1 + 2.3%)⁵
= 13.444956907696116
= $13.44

Percents
Michael is leaving a 15% tip for his waitress. What percent of the
original price will he pay? Write your answer as a percent, decimal,
and fraction.
Answer:
As a percent: 115%
As a decimal: 1.15
As a fraction: [tex]\frac{23}{20}[/tex]
Step-by-step explanation:
Percentages
Suppose Michael spends some amount of money on food, and that money is set at 100%. He leaves a 15% tip for the waitress.
Thus, he is really paying 100%+15% = 115% of the original price.
To express a percentage as a decimal, we just divide by 100:
115% = 115/100 = 1.15
The same division should be simplified instead of operated to express the percentage as a fraction:
115% = [tex]\frac{115}{100}[/tex]
Simplifying by 5:
115% = [tex]\frac{23}{20}[/tex]
Summarizing:
As a percent: 115%
As a decimal: 1.15
As a fraction: [tex]\frac{23}{20}[/tex]

Identify the coefficient of x.
Equation
Answer:
A coefficient is a number in front of a variable. For example, in the expression x 2-10x+25, the coefficient of the x 2 is 1 and the coefficient of the x is -10. The third term, 25, is called a constant.
Step-by-step explanation:
−9x+y= \,\,71 71 -x-y= −x−y= \,\,-1 −1 \mathbf{Add}\text{ to eliminate }\mathbf{y.}Add to eliminate y. \mathbf{Subtract}\text{ to eliminate }\mathbf{x.}Subtract to eliminate x. \mathbf{Subtract}\text{ to eliminate }\mathbf{y.}Subtract to eliminate y. \mathbf{Add}\text{ to eliminate }\mathbf{x.}Add to eliminate x.
Answer:
Add to eliminate y.Step-by-step explanation:
Given the equations
-9x + y = 71.... 1
-x - y = -1 .... 2
Using elimination method we can eliminate y first since they have the same coefficient.
To do that we will need to add up both equations. We are adding because the coefficient of y in both equations has different signs. If they have the same sign, we would have subtracted.
Hence the correct option in this case is to add to eliminate y.

Select the graph for the solution of the open sentence. Click until the correct graph appears.
IX - 1l <4
Answer:
Here we can not see the options, so i will find the graph by the equation alone.
We start with:
Ix - 1I < 4
We could rewrite this as:
-4 < (x - 1) < 4
Now we can add 1 in the 3 parts, to get:
-4 + 1 < x - 1 + 1 < 4 + 1
-3 < x < 5
This means that the graph will be such that:
x > -3 (this is a dashed line at x = 3, and we shade the part in the right of that line)
and:
x < 5 (this is a dashed line at x = 5, and we shade the part in the left of that line)
The graph would look something like the one below
(If the graphs are only in one axis, you should see a white dot at x = -3, than a colour line that goes to the right until the point x = 5, where we have another white dot)

Find the length of side x in the simplest radical form with a rational denominator
Answer:
The value of x = 1
Step-by-step explanation:
Given
hypotenuse = √2 angle Ф = 45°To determine
x = ?
Using the trigonometric ratio
cos Ф = adjacent / hypotenuse
here
Ф = 45°
adjacent of 45° = x
hypotenuse = √2
so substituting Ф = 45° adjacent = x and hypotenuse = √2 in the equation
cos Ф = adjacent / hypotenuse
[tex]\cos \left(45^{\circ \:}\right)=\frac{x}{\sqrt{2}}[/tex]
switch sides
[tex]\frac{x}{\sqrt{2}}=\cos \left(45^{\circ \:}\right)[/tex]
Multiply both sides by 2
[tex]\frac{2x}{\sqrt{2}}=2\cos \left(45^{\circ \:}\right)[/tex]
[tex]\sqrt{2}x=\sqrt{2}[/tex] ∵ [tex]\cos \left(45^{\circ \:}\right)=\frac{\sqrt{2}}{2}[/tex]
Divide both sides by √2
[tex]\frac{\sqrt{2}x}{\sqrt{2}}=\frac{\sqrt{2}}{\sqrt{2}}[/tex]
[tex]x=1[/tex]
Therefore, the value of x = 1

The vertices of a triangle are P[4.1). Q(2.-8), and R(-8.1). What are the vertices of the image reflected across the y-axis?
O A P14.-1), Q12,8), and RX-8.-1)
B. PY-4. 1). Q1-2.-8), and R(8.1)
OC. P(-4,-1). QT-2,8), and R18.-1)
OD. P14.1). Q12.-8), and R1-8.1)
Given:
The vertices of a triangle are P(4,1), Q(2,-8), and R(-8,1).
To find:
The vertices of the image reflected across the y-axis.
Solution:
The vertices of a triangle are P(4,1), Q(2,-8), and R(-8,1). It is reflected across the y-axis.
If a figure is reflected across the y-axis, then
[tex](x,y)\to (-x,y)[/tex]
Using this rule, we get
[tex]P(4,1)\to P_1(-4,1)[/tex]
[tex]Q(2,-8)\to Q_1(-2,-8)[/tex]
[tex]R(-8,1)\to R_1(8,1)[/tex]
So, the vertices of the image are [tex]P_1(-4,1), Q_1(-2,-8), R_1(8,1)[/tex].
Therefore, the correct option is B.
Note: Options are not in proper form.
Answer:
P'(–4, 1), Q'(–2, –8), and R'(8, 1)
