This isn't true because the exact answer of a system is where the lines cross each other, not where they cross a grid.

Answer:

The correct option is A

Step-by-step explanation:

Since (1, 3) are the solutions to the function g(x), then

g(x) = (x – 1)(x – 3) = x² –3x – x + 3 = x² – 4x + 3

We know that f(x) is on the same plane and f(1) = 1.

Let's take g(1) = (1 – 1)(1 – 3) = 0

Therefore, when x = 1; f = 1 and g = 0. Hence

g(1) = f(1) – 1

In order words, g(x) could be f(x) – 1.

The correct option is A

If the ratio of the arc length to r is 1, then the measure of is 1 radian.
bixtya [17]
Well the radian is the measure of the radius
this line measure is then ligned up to the circumference
mearuse of 1 raidan is always equal to the measure of the radius therfor the true statements are

ratio of arc legnth to r is always equal to 1

I'm not sure what 'if the measure of is'

but I think the answer is
if the measure of is 1 radis, than the arc legnth is r since r reaprensents radius

so first and third choice are correct

Determine the number of cement blocks needed to put up a wall measuring 20 meters in length and 1.5 meters in height. Each block
Montano1993 [528]

calculate area of wall

20 x 1.5 = 30 square meters

 now calculate area of 1 block

12 x 18 =216 square centimeters

 convert cm to meters  1 cm^2 = 0.0001m^2

 so 216 x 0.0001 = 0.0216 sq meter for 1 block

 divide area of wall by area of block

30/0.0216 = 1388.88 so 1389 blocks are required.
