Step-by-step explanation:
Simplify the expression
0.5, 0.9, 1.3, 1.7, 2.1, 2.5, 2.9, 3.3, 3.7, 4.1
Now you can add them all
which is equal to 23
The equation of the quadratic function f whose graph is shown below is x² + 6.1x + 8.2
Find the diagram attached.
First, we need to get the zeros of the required function. The point where the curve cuts the x-axis is the zeros.
According to the graph, the curve cuts the x-axis at x = -2 and x = -4.1
The required factors will be (x+2) and (x+4.1)
Taking the product of the factors
f(x) = (x+2)(x+4.1)
f(x) = x²+4.1x+2x +8.2
f(x) = x² + 6.1x + 8.2
Hence the equation of the quadratic function f whose graph is shown below is x² + 6.1x + 8.2

Hi there! I can help you! The slope-intercept formula is y = mx + b, where m = slope, b = y-intercept, and y and x remain unfilled. The formula for finding slope is y2 - y1 / x2 - x1, where you subtract the values of the first coordinate from the second coordinate. Let's use the points (26, -12) and (30, -24). Set it up like this:
-24 - (-12)/ 30 - 26
-24 + 12 is -12. 30 - 26 is 4. -12/4 is -3. The slope is -3. Now, let's solve for the y-intercept. 0 will be filled in as the x value. We will use one of the points on the line to help answer this question. Let's use the point (26, -12). The problem becomes -12 = -3(26) + b. Now, let's solve. -3 8 26 is - 78. Now, we add 78 to isolate the b. -12 + 78 is 66. There. b = 66. The formula for the table in y-intercept form is y = -3x + 66.
Answer:
B(2;4) C(1;0)
Step-by-step explanation:
the shift is (x+3)-1....meaning 3 units to the left and 1 unit downwards
