how many solutions does this have 2x + 2 = 2(x + 1)
Answer:
Infinitely Many Solutions
Step-by-step explanation:
You distribute 2 into x+1
2x+2=2x+2
Subtract 2x from both sides.
2=2
Since 2 does equal 2, there are infinitely many solutions.
Graph the equation y= -x^2 +10x-21 on the accompanying set of axes. You must plot 5 points including the roots and vertex. Using the graph, determine the vertex of the parabola
Answer:
The properties of the parabola equation are
Vertex = (-5, -4)
Roots = (-7, 0) and (-3, 0)
Points = (-2, 5) and (-4, -3)
What are parabola equations?
Parabola equations are second-order polynomial equations and they have the form y = ax^2 + bx + c or y = a(x - h)^2 + k
How to plot the graph of the parabola?
The equation is given as
y = x^2 + 10x + 21
Next, we plot the graph on the coordinate plane
On the graph, we can see the following properties

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30

Solve each of the following equations
1-|3p+1|=-3
Answer:
p=1 p = -5/3
Step-by-step explanation:
1-|3p+1|=-3
Subtract 1 from each side
1-|3p+1| -1=-3-1
-|3p+1|=-4
Divide by -1
|3p+1|=4
The absolute value has two solutions one positive and one negative
3p+1 = 4 3p+1 = -4
Subtract 1 from each side
3p+1-1 = 4-1 3p+1-1 = -4-1
3p = 3 3p = -5
Divide by 3
3p/3 = 3/3 3p/3 = -5/3
p=1 p = -5/3
Answer:
p=-5/3,1
Step-by-step explanation:
Subtract 11 from both sides.
-|3p+1|=-3-1
−∣3p+1∣=−3−1
2 Simplify -3-1−3−1 to -4−4.
-|3p+1|=-4
−∣3p+1∣=−4
3 Multiply both sides by -1−1.
|3p+1|=4
∣3p+1∣=4
4 Break down the problem into these 2 equations.
3p+1=4
3p+1=4
-(3p+1)=4
−(3p+1)=4
5 Solve the 1st equation: 3p+1=43p+1=4.
p=1

Answer:
35, 100, 1.4
Step-by-step explanation:
Each value of 10 would equal 7. This would mean that 50 would equal 35 since 7x5=35. This would also mean that 100 would equal 70 since 7x10=70. This would also make sense for the last one since 10÷3=1.4
Answer:35, 100, 1.4

Which number has a 9 that is 1/10 the value of the 9 in 296?
195
409
981
1,956
Answer:
409
Step-by-step explanation:
This is very easy. First of all you need to workout out 1/10 of the value of the 9 in 296. The value of the 9 in 296 is 90.
1/10 of 90 is 9 (since 1/10 x 90 = 90/10 = 9)
The only number which has 9 as its final digit is 409

Find the mean of the integers: 17, -25, 3, -29, -15, 7
Answer: -7
Step-by-step explanation: To find the mean, here is the equation =
Divide the sum of all values in a data set ÷ the number of values = mean (average)
Step 1 :
So we do =
17 + -25 + 3 + -29 + -15 + 7 = -42
So the sum of the integers is -42
Step 2 :
We divide the sum by the number of values.
17, -25, 3, -29, -15, 7
1 2 3 4 5 6
So there are 6 values.
We do =
-42 ÷ 6 = -7
So the mean (average) of these integers is -7

In this problem, the question asks us for 3 parts
a) the predicted hourly pay rate for a cashier who doesn't have any experience.
In this problem, the scatterplot was reduced into a linear function modeled by the equation y=0.94x+7.86 where y is the pay in $ per hour and x is years of experience indicating pay is dependent on the independent factor of years of experience. 0 years when plugged into the equation yields this through substitution. 0.94(0)+7.86=7.86$ which is the y-intercept
b)this is simply substitution as one can plug in 7 as x 0.94(7)+7.86=14.44$ or appx. 14$
c) for this problem it asks us the predicted difference in the hourly pay rate however the equation y=0.94x+7.86 tells us for every x year pay goes up an average of 0.94$, therefore, the increase is 0.94$.
Overall, this problem challenges the student's understanding of linear equations and the meaning of x and y in relation to one another in a graph.
Use the best-fit line below to predict the value of y when x = 7
Answer:
the answer is 6 because when x=7 on the line it is also equal to 6 on the y axis
