The dashed-line triangle is a dilation-reduction, and the scale factor is (1/3). Note how the former triangle is 1/3 the size of the larger one.

40Points? CORRECT answer please

Answer:

Step-by-step explanation:

$f(t)=2(0.4)^t$

f(-2) → put t = -2 to the equation of the function:

$f(-2)=2(0.4)^{-2}=2\left(\dfrac{4}{10}\right)^{-2}=2\left(\dfrac{2}{5}\right)^{-2}$

Use $a^{-n}=\left(\dfrac{1}{a}\right)^n$

$f(-2)=2\left(\dfrac{5}{2}\right)^2=2\left(\dfrac{25}{4}\right)=\dfrac{25}{2}=12.5$

(4,7), (x,19); slope = 3 the pair points lies on the same line with the given slope. Find x

Andrew [12]

So we are given two points, say P1(4,7), P2(x,19).

Slope is given by
m=3=(y2-y1)/(x2-x1)=(19-7)/(x-4)
solve for x
3=(19-7)/(x-4)
cross multiply
3(x-4)=12
3x-12=12
3x=12+12=24
x=8
