The line is given by equation y–1.5x = c. What is the value of c if the line passes through the point K (2, –3).
aleksandr82 [10.1K]

Answer:

c = -6

Step-by-step explanation:

To find the value of c to make the line pass through the point K = (2, -3), we just need to use the values of x = 2 and y = -3 in the equation, then we find the value of c.

So, we have that:

y - 1.5*x = c

(-3) - 1.5 * (2) = c

-3 - 3 = c

c = -6

So the value of c is -6

To check if the value is correct, we can use the value x = 2 and see if the value of y is -3:

y - 1.5*x = -6

y - 1.5*2 = -6

y - 3 = -6

y = -6 + 3 = -3

So it's correct.

what is the value of a for the exponential function in the graph represented in the form of f(x)=a(b^x)? Zoom in the photo bcz i
nekit [7.7K]

Answer:

a = 3

Step-by-step explanation:

To determine the value of a, we want b^x to be 1, so that f(x) = a \times 1. Notice that if x = 0, then f(0) = a \times (b^0) = a, so the value of a is simply f(0). From the graph, it appears that f(0) = 3, so therefore a = 3.
