find the values of x and z.​

Answer:

y = -5x-19

Step-by-step explanation:

Use the point-slope formula to plug in the x1 and y1 and the slope -5 to get the equation y = -5x-19.

Formula: y-y1 = m(x-x1)

m = slope

x1 = x-value

y1 = y-value

Answer:

y=-5x-15

Step-by-step explanation:

starts off in point-slope form:

y+4=-5(x+3)

distribute the 5:

y+4=-5x-15

subtract 4 from each side:

y=-5x-20

^that answer is in slope intercept form.

Answer:

Step-by-step explanation:

The given statement is the scale factor:

  [tex]\dfrac{\text{scale distance}}{\text{actual distance}}=\dfrac{1\text{ cm}}{2\text{ m}}[/tex]

This can be rearranged to the formula ...

  [tex]\text{actual distance}=\text{(scale distance)}\dfrac{2\text{ m}}{1\text{ cm}}[/tex]

Filling in the given scale distances, you find the actual distances to be ...

  [tex]\textbf{(a) }(14\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=14\cdot2\text{ m}=28\text{ m}\\\\\textbf{(b) }(7.5\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=7.5\cdot2\text{ m}=15\text{ m}\\\\\textbf{(c) }(12.4\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=12.4\cdot2\text{ m}=24.8\text{ m}\\\\\textbf{(d) }(0.5\text{ cm})\dfrac{2\text{ m}}{1\text{ cm}}=0.5\cdot2\text{ m}=1.0\text{ m}\\\\[/tex]

(-8/3)/(-2/6)

negative times negative equals positive

simplify -2/6 to -1/3 AND FLIP THE -1/3 TO -3/1

-8/3*-3/1

cancel out the 3s and make them 1s

cancel out the negatives and make them positive

8/1 = 8

answer:

72

step-by-step explanation:

your question doesn't make mathematical sense how can 12 = 6 then subract 90?

maybe you meant 12 + 6 - 90

if so

the answer is

72

(my work)

12 + 6 = 18

18 - 90 = 72

Answer: 13x -8y

Hey there!

To get started we need to figure out what the equation is by remembering the sum is addition.

6x-y + 7x-7y

Then we need to combine like terms

(6x+7x) (-7y-y)

to get...

13x-8y

Answer:

x = -5/4

Step-by-step explanation:

3x= 5+7x    (subtract 7x from both sides)

3x - 7x = 5

-4x = 5    (divide both sides by -4)

x = 5/(-4)

x = -5/4

The vertex form of an equation of the parabola with vertex (-1,-3) is:

where a  could be any number, also -2,

Step-by-step explanation:

The vertex form of an equation of the parabola:  

                                                        y = a(x - h)² + k

vertex is (-1, -3)  so  h = -1,  k = -3

so:

   y = a(x - (-1))² + (-3)

   y = a(x + 1)² - 3

Answer:

- (x - 4)(x - 11)

Step-by-step explanation:

Given

- x² + 15x - 44 ← factor out - 1 from each term

= - 1 (x² - 15x + 44) ← factor the quadratic

Consider the factors of the constant term (+ 44) which sum to give the coefficient of the x- term ( - 15)

The factors are - 4 and - 11 , since

- 4 × - 11 = + 44 and - 4 - 11 = - 15 , thus

x² - 15x + 44 = (x - 4)(x - 11) and

- x² + 15x - 44 = - (x - 4)(x - 11)

Answer:

if -5n+7<57, then n>-10.

if 6n+2<8, then n<1.

Step-by-step explanation:

-5n+7<57

1. subtract 7 from both sides:

-5n+7 -7< 57 -7

-5n<50

2. divide both sides by -5 (remember to flip the sign whenever you divide by a negative number):

-5n ÷-5<50 ÷-5

n>-10

6n+2<8

1. subtract 2 from both sides:

6n+2 -2<8 -2

6n<6

2. divide both sides by 6:

6n ÷6<6 ÷6

n<1

Step-by-step explanation:

The population of town A is 4.5 times greater than the population of town B.

The power of a number describes how many times a number is multiplied by itself.

Given are the population of two towns A and B.

Town A has a population of 1.26×10⁵ and the population of town B is 2.8×10⁴.

To find how many times greater is the population of Town A than the population of Town B we have divide the population of town A by the population of town B which is,

= ( 1.26×10⁵)/(2.8×10⁴) times greater.

= (12.6)/(2.8).                                       ( 10⁵ divided by 10⁴ is 10¹ which is 10)

= 4.5 times greater.

Answer:

identity property of multiplication (multiplying a number by one will result in that number)

Step-by-step explanation:

Answer:

1) = 180 degree reason = being AB is a straight line or supplementary

2) = angle AOB reason = being all the angles are of a straight line AB

3) = x + 2x+34 + 20 = 180 degree. reason being supplementary angle

4) = 42 degree

1) fill 180° in the blank

Reason :

Because AOB angles is half a page so it equals 180°

_________________________________

2)fill 180° in the blank

Reason :

AOE + EOF + FOB = AOB

And we have found that AOB angles is half a page so it equals 180°

A pentagonal prism is a prism having two pentagonal bases and five rectangular sides. It is a heptahedron.

The regular right pentagonal prism is uniform polyhedron . Its dual polyhedron is the pentagonal dipyramid.

The surface area and volume for the right regular pentagonal prism of unit edge length are

V = 1/4sqrt(5(5+2sqrt(5))).

v < −5  or  v > 5

We know either v+8<3 or −8v<−40

Possibility 1

v+8<3

v+8−8<3−8

Subtract 8 from both sides

v<−5

Possibility 2

−8v<−40

−8v  −8  <  −40  −8

Divide both sides by -8

Answer:

-2 =a

Step-by-step explanation:

6-4(a+2)=8+a

Distribute

6 - 4a - 8 = 8+a

Combine like terms

-2 -4a = 8+a

Add 4a to each side

-2-4a+4a=8+a+4a

-2 = 8+5a

Subtract 8 from each side

-2-8 = 8+5a -8

-10 = 5a

Divide each side by 5

-10/5 = 5a/5

-2 =a
