Answer:

x= - [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Given

- 6x + 9 - 4x = 14, that is

- 10x + 9 = 14 ( subtract 9 from both sides )

- 10x = 5 ( divide both sides by - 10 )

x = [tex]\frac{5}{-10}[/tex] = - [tex]\frac{1}{2}[/tex]

Answer:

coordinates of R(x,y) is R(6,-2).

Step-by-step explanation:

A. we know that

The rectangle has coordinates P (-1,2), Q(2,4), R(x,y) and S(3,-4)

using a graph tool

see the attached figure

Step 1

Find the slope of the line PS

the slope is equal to

m=(y2-y1)/(x2-x1)

mPS=(-4-2)/(3+1)=-6/4=-3/2

Step 2

Find the equation of the line QR

we know that

PS and QR are parallel lines

so

their slopes are the same

mQR=-3/2

with mQR and the point Q(2,4) find the equation of the line

y-y1=m*(x-x1)

y-4=(-3/2)*(x-2)

y=(-3/2)*x+3+4--------> y=7-(3/2)*x

Step 3

Find the equation of the line SR

we know that

SR and QR are perpendicular lines

so

the product of their slopes is equal to minus one

mSR*mQR=-1

mSR=2/3

with mSR and the point S(3,-4) find the equation of the line SR

y-y1=m*(x-x1)

y+4=(2/3)*(x-3)

y=(2/3)*x-2-4---------> y=-6+(2/3)*x

Step 4

Find the intersection of the lines QR and SR

we know that

the intersection of the lines QR and SR is the point R

y=7-(3/2)*x------> equation 1

y=-6+(2/3)*x------> equation 2

equate equation 1 and equation 2

7-(3/2)*x=-6+(2/3)*x

7+6=(2/3)*x+(3/2)*x

13=(2/3)*x+(3/2)*x

Multiply by 6 both sides

6*13=4*x+9*x

13*x=6*13

x=6

find the value of y

y=-6+(2/3)*x------> y=-6+(2/3)*6---------> y=-6+4

y=-2

therefore, the coordinates of point R are (6,-2)

Answer:

They are equal

Step-by-step explanation:

If you do 2 plus 4 in the parentheses then that equals 6 and 6t time 2 is 12t because the t doesnt have a value therefore it sticks onto the answer and if you convert the 3/4 into .75 then you can subtract the 24 by 8t and get 16 then when you multiply the 16 by 3/4 it will take .75 off of 16 and the answer is the same therefore they are equal equations.

Answer:

need to solve the equation 150 = -6x2 + 100x - 180. I can subtract 150 from both sides and use the quadratic formula to find x = 4.53 and 12.13. This means that if the store sells soccer balls for $4.53 or $12.13, it will earn a daily profit of $150.

Answer:

7.2

Step-by-step explanation:

The distance of FG is 7.211

Distance between two points (x1,y1) and (x2,y2) is given by:

PQ = √( x2 − x1 )² + ( y2 − y1 )². It is known as distance formula.

Given coordinates:

F(0, – 7) and G (-6, -3).

Using distance formula

= √(-6-0)² + (-3 +7)²

=√36+ 16

=√52

=7.211 units

Hence, the distance of FG is 7.211 units

Step-by-step explanation:

here is the answer with the solution.

Answer:

The answer is all real numbers

Step-by-step explanation:

Simpify both sides of the equation: 14−(2y+5)=−2y+9

14+−1(2y+5)=−2y+9(Distribute the Negative Sign)

14+−1(2y)+(−1)(5)=−2y+9

14+−2y+−5=−2y+9

(−2y)+(14+−5)=−2y+9(Combine Like Terms)

−2y+9=−2y+9

−2y+9=−2y+9

Then add 2y to each side. −2y+9+2y=−2y+9+2y

9=9. Then subtract 9 from each side. 9-9=9-9=0. That means that all real numbers is the answer.

Hey there!

[tex]Answer:\boxed{\text{All are solutions}}[/tex]

[tex]Explanation:[/tex]

[tex]14-(2y+5)=-2y+9[/tex] Equation

14−(2y+5)=−2y+9 Simplify both sides

14 + -1(2y + 5) = −2y + 9 Distribute Negative

14 + -1(2y) + (-1)(5) = -2y + 9

14 + −2y + −5 = −2y + 9

(−2y) + (14 + −5) = −2y + 9 Combine the like terms

−2y + 9 = −2y + 9

-2y + 9 + 2y = -2y + 9 + 2y Add 2y to both sides

9 = 9

9 - 9 = 9 - 9 Subtract 9 from both sides

0 = 0

All are solutions.

Hope this helps!

Answer:

See below

Step-by-step explanation:

Point A (-4,3)

Point A is in quad 2

So, . . . Point A' will be in quad 4 (+,-)

Therefore, you switch the signs.

Point A' (4,-3)

The new position of the point (-4,3) will be (4,-3) after rotation.

The process of changing the location of the image on the coordinate system will be known as the translation. An object is rotated by turning it around the center of rotation, which is a point.

Given that point A is located at coordinates (-4,3). The new coordinates of A' after a rotation of 180 degrees using (0,0) as the center of rotation.

As it is given point A is rotated about the origin at 180 degrees. Then the new coordinates of the points will be at the same magnitude but with the opposite sign.

Point A (-4,3)

Point A' will be in quadrant 4 ( +,- )

Point A' = ( 4, -3).

Therefore, the new position of the point (-4,3) will be (4,-3) after rotation.

Answer:

[tex]x_1=-\frac{3}{2} \\\\x_2=-1[/tex]

Step-by-step explanation:

the general fromula is

[tex](ax+b)(cx+)d)\\\\=acx^{2} +(ad+bc)x+bd[/tex]

so we need that

[tex]ac=2\\\\ad+bc=5\\\\bd=3[/tex]

for ac = 2

we only have 2 and 1

so let's say

[tex]a=2\\\\c=1[/tex]

so we now have

[tex](2x+b)(x+d)\\\\2x^{2} +(2d+b)x+bd\\\\[/tex]

and for bd = 3

we only have 3 and 1

but we need to

2d +b = 5

so we can have

b=3

and

d=1

so the factorized form is

[tex](2x+3)(x+1)[/tex]

so we come back to

[tex](2x+3)(x+1)=0[/tex]

so here we have two cases

Case 1

[tex](2x+3)=0\\\\2x+3=0\\\\2x=-3\\\\x=-\frac{3}{2}[/tex]

Case 2

[tex](x+1)=0\\\\x+1=0\\\\x=-1[/tex]

Answer:1. 0.35. 0.35

Step-by-step explanation:

I did the question on edgenuity

The change for each consecutive time given is: 1

The change of each consecutive height given is: 0.35

The rate of change for the relationship between time and height is: 0.35

The table that displays the height of water when a pool is being filled against time is shown in the image attached. (See attachment).

Recall:

Rate of change can be calculated as: change in output / change in input

Change in output = difference between consecutive outputs

Change in input = difference between consecutive inputs

In the question given,

Time is input

Height is output

Thus:

Change for each consecutive input (time):

Therefore, the change of each consecutive input (time) is: 1

Change for each consecutive output (height):

Therefore, the change of each consecutive output(height) is: 0.35

Rate of change of the relationship between time and height:

Rate of change = change in height / change in time

Rate of change = 0.35/1 = 0.35

In summary:

The change for each consecutive time given is: 1

The change of each consecutive height given is: 0.35

The rate of change for the relationship between time and height is: 0.35
