What is the value of a + bc when a=7, b = 4 and c = 1/2

1 answer:

5 0

The value is 7 + 4(1/2), which equals 9.

7 + 4(0.5) = 7 + 2 = 9

The line of best-fit that represents the relationship between velocity and time is:

v = 2.19t + 6.7.

<h3>How to find the equation of linear regression using a calculator?</h3>

To find the equation, we need to insert the points (x,y) in the calculator.

For this problem, the points (t,v) are given as follows:

(0, 6.1), (2.1, 12.2), (5.3, 17.4), (8.2, 26.4), (10, 28.1), (12.1, 32.8).

Hence, inserting these points into a calculator, the equation is given by:

v = 2.19t + 6.7.

Solid is if x is greater/less than or equal to (there isn’t a symbol for it) the line and the line would be dashed if x is < or > something

You should actually have

$-x^2-4x-10=-(x^2+4x+10)=-(x^2+4x+4+6)=-((x+2)^2+6)=-(x+2)^2-6$

Now, remember that $x^2$ is always non-negative, so $(x+2)^2\ge0$ for any value of $x$ . This means $-(x+2)^2\le0$ for any $x$ , and so

$-(x+2)^2-6\le0-6=-6$

i.e. f(x) is at most -6, and hence negative for all $x$ .
