Can someone please help me please?
Explanation:
For now, let's ignore the blue curve.
If we kept the red curve completely fixed in place, and only moved the xy axis, then we can move the xy axis 5 units to the right to give the illusion the red curve is moving (even though it's fixed in place).
Moving the xy axis 5 units to the right means each x input is 5 units larger. So x jumps up to x+5
In other words, going from f(x) to f(x+5) will shift the f(x) curve 5 units to the left. So that's why we go from x^2 to (x+5)^2 which is what choice D shows.

The length of a football field should be measured in yards
Hi! I'm happy to help!
We know that a football field is separated into 100 (numbers marked on the field.) A football field is also 100 yards, so it would be reasonable to measure it in yards.

Shelly has 7/8 cup of lemonade. She pours 1/4 cup of lemonade in each glass. How many glasses can Shelly fill?
=============================================================
Explanation:
We can think of a similar problem involving [tex]8 \div 4[/tex] which could answer the question "if she has 8 cups and pours 4 cups per glass, then how many glasses can she fill?" (that answer being 2 glasses).
Then we replace the 8 with 7/8, and we also replace the 4 with 1/4. It's the same idea but now things have gotten a bit more complicated since we're dividing two fractions.

What pattern can you see in the graph of y = 10x for x ≥ 0?
Graphs are used to show the relationship between two variables. In the given graph, as the value of x increases, the value of y decreases.
Given that:
[tex]y = \frac{10}{x}[/tex]
The above function is an inverse function.
This means that:
As the value of x increases, the value of y decreases
Take for instance:
[tex]x= 1[/tex]
[tex]y = \frac{10}{1} = 10[/tex]
Now, [tex]x = 2[/tex]
[tex]y = \frac{10}{2} = 5[/tex]
Notice that:
As x increases from 1 to 2, the corresponding values of y decreases from 10 to 5
Hence, (b) is correct

The correct option is (a) i.e. Regression equations are usually used to predict values of unavailable data. If the data do not closely model a particular type of function, then that type of function is not appropriate to use in statistical regression. The more closely data fit a model, the more accurate predicted values will be.
What is Regression analysis?
A collection of statistical techniques known as regression analysis is used to estimate the associations between a dependent variable and one or more independent variables. It can be used to simulate the long-term link between variables and gauge how strongly the relationships between them are related.
Although there are non-linear regression techniques for more complex data and analysis, simple linear regression and multiple linear regression are the two fundamental types of regression. While multiple linear regression employs two or more independent factors to predict the outcome, simple linear regression just uses one independent variable to explain or predict the outcome of the dependent variable Y. (while holding all others constant).
Professionals in other industries, including banking and investment, might benefit from regression. Regression can also aid in predicting sales for a business based on external factors like the weather, past sales, GDP growth, and other variables. A popular regression model in finance for valuing assets and calculating capital expenses is the capital asset pricing model (CAPM).

Write an equation in Point-Slope Form with a slope of 23and passes through the point (−4,3).
Answer:
y = 23x + 95
Step-by-step explanation:
y = mx + b, where m is the slope and b is the y-intercept
The equation of line with a slope of m = 23
y = 23m + b
Since the point (-4,3) is on the line, it will satisfy the equation.
3 = 23(-4) + b
b = 3 - 23(-4)
b = 95
y = 23x + 95

4)
(x + 3)² + (y – 4)² =√44
Answer:
Formula used :
x²+2xy+y² = (x+y)² x²-2xy+y² = (x-y)²[tex] →{x}^{2} + 6x + {y}^{2} - 8y = 19 \\ ({x}^{2} + 2.3.x + {3}^{2} ) +({y}^{2} - 2.4.y + {4}^{2} ) = 19 + {3}^{2} + {4}^{2} \\ {(x + 3)}^{2} + {(y - 4)}^{2} = 19 + 9 + 16 \\ \boxed{ {(x + 3)}^{2} + {(y - 4)}^{2} = 44}✓[/tex]

Can someone help me understand number 5 plz!!!!
=================================================
Explanation:
The picture is shown below of what's going on.
The location of point C isn't really important. What is important is the idea that if BC = 3x-8, then AB is also this length as well. The midpoint B cuts segment AC into two equal pieces AB and BC. So that's why AB = BC.
Let's find the distance from A to B
We'll use the aptly named distance formula to get this done (the pythagorean theorem is an alternative route you can take)
[tex]A = (x_1,y_1) = (8,0)\\\\B = (x_2,y_2) = (0,6)\\\\d = \text{distance from A to B} = \text{length of segment AB}\\\\d = \sqrt{(x_1 - x_2)^2 + (y_1 - y_2)^2}\\\\d = \sqrt{(8-0)^2 + (0-6)^2}\\\\d = \sqrt{(8)^2 + (-6)^2}\\\\d = \sqrt{64 + 36}\\\\d = \sqrt{100}\\\\d = 10\\\\[/tex]
Therefore, segment AB is 10 units long. Segment BC is also 10 units long.
From here, we can say this:
BC = 3x-8
3x-8 = BC
3x-8 = 10
3x = 10+8
3x = 18
x = 18/3
x = 6 which is the final answer
Throughout this whole process, we never needed to know the location of point C. However, if you're curious about how to find it, then you basically would apply the midpoint formula in reverse.
