Step-by-step explanation:

b = what Bernie earns per day = Php 1000

m = what Mitch earns on a given day

e = what Eugene earns on a given day

r = what Rowan earns on a given day

t = the total earnings of Bernie and Mitch on a given day

t = m + 1000 (or m + b)

e = m/2

r = 2×(m + 1000) or 2×t

On the grid draw a scaled copy of quadrilateral ABCD with a scale factor 2/3

Tamiku [17]

Answer:

Attached diagram A'B'C'D'

Step-by-step explanation:

Given is a quadrilateral ABCD. It says to draw a dilated version with a scale factor 2/3.

We see that scale factor is less than 1 which means it shrinks the image to a smaller one.

To draw a scaled copy, we need to find the lengths of its sides.

To do so, we can draw the diagonals AC & BD, and they intersect at origin O(0,0) such that OA= -2, OB= 2, OC= 4, OD= -4.

Applying a scale factor of 2/3, we get OA' = -4/3, OB' = 4/3, OC' = 8/3, OD' = -8/3.

So we have attached a scaled copy A'B'C'D' of quadrilateral ABCD with a scale factor 2/3.

What is f[g(3)] for the following function? <br> f(x) = 4x2 − 3<br><br> g(x) = 5x − 2

lukranit [14]

Answer:

673

Explanation:

f(x) = 4(x)² − 3

g(x) = 5(x) − 2

solve:

f[g(3)]

f(5(3) − 2)

f(13)

4(13)² − 3

What are the coordinates of the orthocenter of △JKL with vertices at J(−4, −1) , K(−4, 8) , and L(2, 8) ?

kompoz [17]

Answer:

K(-4,8) is the ortho center.

Step-by-step explanation:

In a right angled triangle, The vertex of the right angle is the ortho center.

Here we are given

J(-4,-1), K(-4,8) & L(2,8)

Using distance formula we get

$JK^{2}= (-4+4)^{2}+ (8+1)^{2}=0+81=81$

$KL^{2}= (-4-2)^{2}+ (8+-8)^{2}=36+0=36$

$JL^{2}= (-4-2)^{2}+ (8+1)^{2}=36+81=117$

So we can say that

$JK^2 + KL^2=JL^2$

By converse of pythagorean theorem we get

Hence the Vertex of the right angle is K(-4,8)

K(-4,8) is the ortho center.
