which of the following represents the equation of the line with an x- intercept of 6 that passes through the point (4,4)?

luda_lava [24]

Answer:

$y=-2x+12$

Step-by-step explanation:

To write the equation of a line, find the slope between two points. Substitute two points into the slope formula. If the equation has an x-intercept of 6 then the line passes through the point (6,0). Use (6,0) and (4,4) in the formula.

$m = \frac{y_2-y_1}{x_2-x_1} =\frac{4-0}{4-6} =\frac{4}{-2} =-2$

Since m = -2, substitute its value and the point (6,0) into the point slope form. Then simplify.

$y-y_1 = m(x-x_1)\\y-0 = -2 (x-6)\\y=-2x+12$

Let f(x)=x+2 and g(x)=2x+1 .

gogolik [260]

Step-by-step explanation:

Given g(x) = x+2 and f(x) = $2^x+1$

If f(x) = g(x)

⇔ $2^x+1$ = x+2

⇔ $2^x= x +1$

Only x= 1 and x=0 will be satisfy the above equation.

If x= 1, it gives and x=0 gives

$2^1= 1+1$ $2^0=0+1$

⇔2=2 ⇔1=1
