Math help plz
Answer:
Step-by-step explanation:
We need three rules. Raising a power to a power. Raising a product to a power. Raising a number to a negative exponent.
Rule 1:
To raise a power to a power, multiply powers.
Rule 2:
To raise a product to a power, raise every factor of the product to the power.
Rule 3:
To raise a number to a negative power, follow this formula.
Your problem.
You have a product raised to a power, so raise each factor to the power.
Now raise each power to a power by multiplying exponents.
Now we follow the rule of a negative exponent.

Answer: Hello, this is Bing. I can help you with your math problem.
To find the equation of the graphed line, we need to identify its slope and y-intercept. The slope is the ratio of the vertical change to the horizontal change between any two points on the line. The y-intercept is the point where the line crosses the y-axis.
Looking at the image, we can see that the line passes through the points (-3, 4) and (3, -2). We can use these points to calculate the slope:
slope = (y2 - y1) / (x2 - x1) slope = (-2 - 4) / (3 - (-3)) slope = -6 / 6 slope = -1
The slope of the line is -1. This means that for every unit increase in x, the y value decreases by 1 unit.
To find the y-intercept, we can use either of the points and plug them into the equation y = mx + b, where m is the slope and b is the y-intercept. For example, using the point (-3, 4), we have:
4 = -1 * (-3) + b 4 = 3 + b b = 1
The y-intercept of the line is 1. This means that the line crosses the y-axis at (0, 1).
Therefore, the equation of the graphed line is:
y = -x + 1
This equation matches with one of the options given below the graph: y = -1/2x + 4. This is because we can multiply both sides of the equation by 2 and get:
2y = -2x + 2 y = -1/2x + 4
Answer: The equation that describes the graphed line is y = -1/2x + 4.
Through the establishment and solution of a linear equation, we can calculate that Becky needs to make 62 total sales to earn at least $2000.
This problem is a case of a linear function in Mathematics, specifically about understanding how to construct and solve a linear equation. First, Becky earns $120 on her first sale. Then, each subsequent sale after the first one earns her an additional $31.50. We set up the equation $120 + $31.50(x - 1) >= $2000, where x is the number of total sales she must make. After solving that equation for x, you'll get around 61.57, but since she can't sell a fraction of a product, we'll round that up to 62. Thus, Becky needs to make 62 sales to earn at least $2000.

Answer:
f(4) = 8
f(6) = 10
Step-by-step explanation:
Step 1: Define
f(x) = x + 4
f(4) is x = 4
f(x) = 10
Step 2: Find f(4)
f(4) = 4 + 4
f(4) = 8
Step 3: Find f(x) = 10
10 = x + 4
x = 6
