Which phrase best describes the translation from the graph y = 2(x – 15)2 + 3 to the graph of y = 2(x – 11)2 + 3?
4 units to the left
4 units to the right
8 units to the left
8 units to the right
The translation of the function y = 2(x - 15)² to y = 2(x - 11)² + 3 is; 4 units to the left.
How to Interpret Graph Translations?
We are given the graph function;
y = 2(x - 15)²
Now, the function above was translated to get;
y = 2(x - 11)² + 3
Now, when we translate a graph to the right, we subtract from the x-value, but if we move the graph to the left, we subtract from the x-value. Thus;
The translation was 4 units to the left.

Please help me with the problem below.
Answer:
67.5 cm^2
Step-by-step explanation:
we know the length and width of the rectangle and the triangle in the compound shape.
The area of the rectangle is 10 times 5 = 50
the area of the triangle is
17-10 = 7
7 times 5 is 35
35/2 = 17.5
50 plus 17.5 = 67.5 cm^2
Answer: 67.5
Step-by-step explanation: Since this is a irregular shape, you have to split the two shapes. The rectangles area is 50, and the triangles is 17.5.
To find the area of a triangle multiply 1/2 × base × height
To find the area of a rectangle multiply base × height

You purchase 100 shares of ravioli den for $45/share. One year later, you sell the shares for $52/share. What was your total gain for your investment in ravioli den?
Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. The total gain for your investment in ravioli den is $700.
What is multiplication?Multiplication is the process of multiplying, therefore, adding a number to itself for the number of times stated. For example, 3 × 4 means 3 is added to itself 4 times, and vice versa for the other number.
The cost of a single share was $45, while the number of shares where 100, therefore, the total cost of purchasing shares is:
Total Cost = $45×100 = $4,500
The selling price of a single share is $52, while the number of shares is the same, therefore, the total selling price is,
Total Selling Price = $52×100 = $5,200
The total gain for your investment in ravioli den is the difference between Total cost and total selling price. Therefore,
The total gain = $5,200 - $4,500 = $700
Hence, The total gain for your investment in ravioli den is $700.

IQ scores are normally distributed with a mean of 100 and a standard deviation of 15.
Out of a randomly selected 2200 people from the population, how many of them
would have an IQ less than 115, to the nearest whole number?
Using the normal distribution, it is found that 1851 people would have an IQ less than 115.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The mean and the standard deviation are given, respectively, by:
[tex]\mu = 100, \sigma = 15[/tex]
The proportion of IQ scores less than 115 is the p-value of Z when X = 115, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{115 - 100}{15}[/tex]
Z = 1
Z = 1 has a p-value of 0.8413.
Out of 2200 people:
0.8413 x 2200 = 1851.

Metal A has a density of 12.7 g/cm3.
55 g of metal A is combined with metal B to create an alloy with mass 90 g and density 10.7 g/cm3.
What is the density of metal B?
Round your answer to 2 decimal places.
Using the given information, the density of metal B is 8.58 g/cm³
Calculating densityFrom the question, we are to determine the density of metal B
From the given information,
55 g of metal A is combined with metal B to create an alloy with mass 90 g
∴ Mass of metal B in the alloy = 90 g - 55 g = 35 g
Now, we will determine the volume of metal A in the alloy
Using the formula,
Density = Mass / Volume
∴ Volume = Mass / Density
Volume of metal A in the alloy = 55/12.7
Volume of metal A in the alloy = 4.33 cm³
Then, we will determine the volume of the alloy
Volume of the alloy = 90/10.7
Volume of the alloy = 8.41 cm³
∴ Volume of metal B in the alloy = 8.41 cm³- 4.33 cm³
Volume of metal B in the alloy = 4.08 cm³
Now, for the density of metal B
Density = mass / volume
Density of metal B = 35 / 4.08
Density of metal B = 8.58 g/cm³
Hence, the density of metal B is 8.58 g/cm³.

Work out the size of angle a and angle b
Answer:
a = 120°
b = 60°
Step-by-step explanation:
Angle a and 60° are suplementary. The sum of supplementary angles is 180° (straight angle).
a + 60° = 180°
a = 180° - 60°
a = 120°
The sum of angles in the quadrilateral is 360°. Notice how two of the angles in the quadrilateral are marked as right angles (angles marked with a square). Each of them is 90°.
b + 90° + a + 90° = 360°
Substitute a with the value calculated in the previous step.
b + 90° + 120° + 90° = 360°
Solve for b.
b + 300° = 360°
b = 60°
Which equation can pair with x 2y = 5 to create an inconsistent system?
The equation that can be paired with x + 2y = 5 to create an inconsistent system is given by:
2x + 4y = 3.
What is a system of equations?A system of equations is when two or more variables are related, and equations are built to find the values of each variable.
An inconsistent system is a system that has no solutions, and it happens when the coefficients of x and y are multiples, and the independent terms are not.
Hence:
x + 2y = 5.
2x + 4y = 3.

In the first table, the first differences are:
3-6 = -3;
2-3 = -1;
3-2 = 1;

We are asked to write the verbal phrase "r decreased by 3" as an algebraic expression.
[tex]\triangle~\fbox{\bf{KEY:}}\star[/tex]
Think about it. "decreased by". If we decrease a number by another number, what happens to the first number?Here we decrease the variable "r" by 3.
Remember, variables always represent some number.
Let's think about it this way...
///\\\////\\\\////\\\///\\\///\\\///\\\///\\\///\\///\\///\\///\\///\//\\///\\\///\\\///\\\///\\///\\\///\
So we have a number r, and we decrease it by 3.
Now its value is less than the original value.
We subtracted 3 from the original value of r, and now its value is less than the original one.
Thus, "decreased by" is the same as "subtracted" in mathematics.
r decreased by 3 ⇒ [tex]\star\large\pmb{r-3}[/tex]
