Mathematics

First because it's a broken line we know it's an inequality.

next we find the slope we can take points (0,4) and (2,0) thus (y2-y1)÷(x2-x1)

substituting any value of x for either x1 or x2 and any value of y for y1 and y2 we can get

slope is -2

so now we can take either points to find the equation by the formula

y-yo=m (x-xo) where m is slope

after substitution we can get

y-4=-2 (x-0)

y=-2x+4

The answer is B because if you think about it for example if the number is 4 and 4 it would give you 8 but that’s even and if you take 3 and 3 will give you 6 also another even so if you have the same two number you can always divide it by two
Hope this helps

More help, im still confused
nevsk [136]

Answer:

a) \frac{1}{3}

b) \frac{4}{5}

Step-by-step explanation:

a) the exponent is 2, therefore the value of \sqrt[2]{9} would go in the place of the base.

b) the exponent is 2, therefore the value of \sqrt[2]{\frac{16}{25} } would go in the place of the base => \frac{\sqrt{16}}{\sqrt{25}} = \frac{4}{5}

How do you solve it A(x+b)-c=d
Vsevolod [243]
Move all the terms to the left side and set equal to zero. Then set each factor equal to zero. 

A= c+d/b+d
