The diagram above, not drawn to scale,shows a triangle, ABC, with area 28units². Show workings.

Valentin [98]

A. (0,-6)
plug in the area to the area formula for a triangle (A=1/2bh). so 28=1/2b(4) [since the height is 4]. divide by 4 (7=1/2b). multiply by 2/divide by 1/2 (14=b). the base equals 14 units long.
B. y=2/3x+4
find the slope of the line (2/3)
the y-intercept is 4

F(x) = -4x + 15 g(x) = 7x^3 Find (f-g)(2)

djyliett [7]

$(f-g)(2)=f(2)-g(2)$

Therefore, find f(2) and g(2) first before subtracting.

$f(x)=-4x+15$

Therefore,

$f(2)=-4(2)+15\\f(2)=-8+15\\f(2)=7$

Then find g(2)

$g(x)=7x^3\\g(2)=7(2)^3\\g(2)=7(8)\\g(2)=56$

Then put f(2) to subtract g(2)

$f(2)-g(2)=7-56\\f(2)-g(2)=-49$

Therefore, the answer is (f-g)(2) = -49.

If f(x)=x^2 - 3 and f(a)=46, what is the value of a? explain

dem82 [27]

You are trying to find what x to put into f(x) to get out 46. To do this, solve the following equation.
$x^{2} -3 = 46$
$x^2 = 49$
$x^2 = \sqrt{49}$
Therefore x = 7 or x = -7

-7, 7
