Step-by-step explanation:

original: 1

Increase 25%: 1.25  if this number becomes 1

1 : 1.25 = x : 1

x = 1 / 1.25 = 0.8   (80%)

Q' = (1, -3) R' =(3,3) S' = (0,2)T' = (-2,-1)

Answers

Answer:

The ordered pair for the vertices for r₍₁₈₀ ₀₎(QRST), is given as follows;

Q' = (-1, -3) R' = (-3, 3) S' = (0, 2) T' = (2, -1)

Step-by-step explanation:

The coordinates of he vertices of the triangle QRST are;

Q(1, 3), R(3, -3), S(0, -2), T(-2, 1)

A rotation of a point with coordinates (x, y) 180° about the origin gives;

The coordinate of the point of the preimage before the rotation = (x, y)

The coordinate of the point of the image after the rotation = (-x, -y)

Therefore we have;

The image of point Q(1, 3) after 180° rotation = Q'(-1, -3)

The image of point R(3, -3) after 180° rotation = R'(-3, 3)

The image of point S(0, -2) after 180° rotation = S'(0, 2)

The image of point T(-2, 1) after 180° rotation = T'(2, -1)

The ordered pair for the vertices for r₍₁₈₀ ₀₎(QRST), is therefore, Q'(-1, -3), R'(-3, 3), S'(0, 2), and T'(2, -1);

Q' = (-1, -3) R' = (-3, 3) S' = (0, 2) T' = (2, -1).

Given that x=6 and y=-4, evaluate each of the following expressions:

A. 5x/3y+x
B. 2x (square) - y (cube)

Answers

Answer:

A. 5x/3y+x=5×6/(3×-4)=30/-12=-10/4=-5/2

B. 2x (square) - y (cube)=2×6²-(-4)³=72--64=72+64=136

A: (5(6))/(3(-4)+(6)) = -5
B: 2(6)^2-(-4)^3 = 136

Substitute the value given as x and y into your expression. For A. , order of operation matters. I assumed the “+x” is part of the denominator.

f(-4); f(x) = x2 + x - 4

Answers

Answer: 8

Step-by-step explanation: In this problem,

we're asked to find f(-4) or the value of the function when x = -4.

To find the value of the function when x = -4,we simply plug in a -4 for

the x in our function and we have (-4)² + (-4) - 4 or 16 + -4 - 4 which is 8.

So f(-4) = 8.

PLEASE HELP ILL GIVE BRAINLESS IM GOING TO FAIL

Answers

x=20
AD= 23
DC= 23
AC= 46


The median means both sides of the line AC are equal.

Therefore: x+ 3 = 2x-17
and we can solve this for x

Subtract x from both sides
x-x = 2x-x -17
3 = x -17

Add 17 to both sides
3 +17 = x -17+17
20 = x

The length of AD is x + 3, replace x with 20:
20 + 3 = 23



The length of DC is the same as AD (because they’re separated by the median) so DC= 46

AC is the length of AD + DC,
23+23= 46.
AC= 46

Solve for x. Round to the nearest tenth.

Calculate the rate of interest if principle is 6000 time is two years and interest 3000

Answers

Answer:

We conclude that the interest rate required to  accumulate simple interest of $3,000 from a principal of $ 6,000.00  over 2 years is 25% per year.

Step-by-step explanation:

Given

Principle P = 6000

Time period t = 2 years

Interest I = 3000

To determine

Interest rate r = ?

Using the formula

I = Prt

r = I / Pt

substituting P = 6000 , t = 2, and  I = 3000

r = 3000 / ( 6000 × 2 )

r =  3000 / 12000

r = 0.25

convering the decimal into percentage: 0.25×100 = 25%

r = 25%

Therefore, we conclude that the interest rate required to  accumulate simple interest of $3,000 from a principal of $ 6,000.00  over 2 years is 25% per year.

Equation used- ($ * 0.15)+$

solve: |2x-1| ≥ 4x+3

Answers

Step-by-step explanation:

consider the sign as equals then

move 2x right side 3 on left

solve it

answer is 2

Question is: 2x - 1 >= 4x + 3

First, join the like terms together.

-> So 2x moves into 4x, meaning it becomes negative -2x on the other side.

-> The number 3 moves into the other side which also becomes negative.

Now the equation will look like this:

- 3 - 1 >= 4x - 2x

- 4 >= 2x

Put 2 on the other side with - 4, and it will divide (not plus or minus as 2 was combined with an unlike term).

It looks like this now:

- 4/2 >= x

- 2 >= x

WORK:

2x + 4y = -16  =

-2x + 2y = -2  =

(^ you need to divide 6 on both sides to get just y) =

6y/6 = -18/6  =

(^ the six’s cancel out) =

y = -3  =

(^ now you have to plug this in to get x) =

2x + 4(-3) = -16  =

2x - 12 = -16  =

(^ you need to add 12 on both sides to get rid of it on the left side to add it to -16 on the right side) =

2x = -4  =

2x/2 = -4/2  =

(^ now you divide 2 on both sides again to get just y, and they will cancel out) =

x = -2  =
