Answer: y + 4 = 1/2(x - 1)

Step-by-step explanation:

The form of a straight line quation is y=mx+b, where m is the slope [(1/2) in this case] and b is the y-intercept (the value of y when x=0).  We can already eliminate two of the options (2nd and 4th) since those slopes are 2.

To decide between y - 4 = 1/2(x +1) and y + 4 = 1/2(x - 1), we can see which equation is true for the point (1,-4):

Does y - 4 = 1/2(x +1) work for (1,-4)?  [i.e., will y = -4 when x=1?]

y-4 = 1/2(1+1)?

y = 5         NO

-----------------------------

Does y + 4 = 1/2(x - 1) work for (1,-4)?    [i.e., will y = -4 when x=1?]

y+4 = 1/2(1-1)

y = -4       YES  

The equation is y + 4 = 1/2(x - 1)

Answer:

well in algebra we work with slope. we do other things but you use this the most.

Step-by-step explanation:

the equation for slope is y=mx+b. mx is the slope and b is the y-intercept. example: y=2x+6. the slope is 2 and the y-intercept is 6.

Answer:

y = x - 2

Step-by-step explanation:

Using any two points to find the slope.    I will using (3, 1) and (7, 5)

Slope = (change in the y values)/(change in the x values)

Slope =  (5 - 1)/(7 - 3) = 4/4  = 1

Next find the y -intercept "b", using the table to find the value of y when x is zero. That point is (0, -2) . So the y-intercept ("b")  is -2

or  use one of the point (7, 5) and substitute into the slope- intercept formula and solve for "b'

y = mx + b

5 = 1(7) + b

5 = 7 + b

-2 = b

Write the equation in the slope-intercept form y = x - 2

Answer:

It looks like its being reflected across y = x, so the rule would be

(x, y) —> (y, x)

Answer:

the answer is 1 & 32/99 (131/99)

Given that we have the slope and a point on the graph we can use the point slope formula to find the equation of the line.

Point-Slope Formula:

y−y1=m(x−x1), where m is the slope of the line and x1 and y1 are x and y coordinates of a given point

2 3/7= 17/7

21/5×17/7= 357/35

357/35= 10 1/5

Step-by-step explanation:

Step-by-step explanation:

Two intersecting lines form 4 angles. Each angle is equal to its opposite as  vertically opposite angles are congruent.

Now, if 3 angles are equal it means 2 adjacent angles are equal too. It makes all 4 angles equal.

Since the sum of all 4 angles is 360°, each of angles is 90°.

This proves the lines are perpendicular.

Answer:

5/6.

Step-by-step explanation:

Because 1/2 + 1/3 = 3/6 + 2/6 = 5/6. It doesn't matter that the rest were carrots, the question is asking how many were peppers and 5/6 were.

Answer:

210

Step-by-step explanation:

6 times 3.5=210

The second part of the trip lasted 0.54 hours

Average speed is the ratio of total distance travelled to total time taken. It is given by:

Average speed = total distance / total time

Since the total distance is 62.5 miles and the average speed is 50 miles per hour, hence:

Average speed = total distance / total time

60 = 62.5 / total time

Total time = 25/24 hours

The first part of the journey takes 0.5 hours, hence:

Time for second part = 25/24 - 0.5 = 0.54 hours

Therefore the second part of the trip lasted 0.54 hours

Answer:

0.4

Step-by-step explanation:

x=2/5

2/5=0.4

Answer:

x=0.4

Step-by-step explanation:

5x=2

Divide 5 on both sides of the equation.

The 5 should be canceled out by its self

And drop the x down, and you should have left

over the 2 divided by 5, which should give you

x=0.4

And 0.4 is already rounded so that should be your final answer.

Step-by-step explanation:

an x-axis reflection negates non-zero y values

Explanation:-

★(i).

A = { 1,2}

⇛ n (A ) = 2

B = { 3,4,5,6}

⇛ n (B) = 4

n(A)+n(B) = 2+4 = 6

★(ii).

The symbol ⇛ means Implies

★(iii).

A = Phi = {}

B = phi = {}

AUB = { } U { } = { }

AUB = phi = { }

(iv).

AUB = BUA is called Commutative law in sets uner union .

★(v).

Null set = Void set = Empty set = { }

Number of elements in the empty set = 0

⇛ Cardinal number of null set is zero (0)

★(vi). If AUB = B then B is the super set and A is the sub set of B

★(vii). A = { 1,2,3,4}

B = {2,4,6,8}

A-B = {1,2,3,4} - { 2,4,6,8}

=> A-B = { 1,3}

★(viii). n(AUB) = 8

n(A) = 6

n(B) = 4

We know that

n(AnB) = n(A)+n(B)-n(AUB)

⇛ n(AnB) = 6+4-8

⇛n(AnB) = 10-8

⇛ n(AnB) = 2

or n(AUB)+n(AnB) = n(A)+n(B)

⇛ 8+ n(AnB) = 6+4

⇛ 8+ n(AnB) =10

⇛ n(AnB) = 10-8

⇛ n(AnB) = 2

Therefore, n(AnB) = 2

Step-by-step explanation:

Hi how u doin ?

[tex]8( - 3d + 2) = 88[/tex]

Let's see what we got here ....

First of all Divide both sides by 8

[tex] \frac{8( - 3d + 2)}{8} = \frac{88}{8} \\ [/tex]

Simplification

[tex] - 3d + 2 = 11[/tex]

Subtract both sides 2

[tex] - 3d + 2 - 2 = 11 - 2[/tex]

[tex] - 3d = 9[/tex]

Divide both sides by - 3

[tex] \frac{ - 3d}{ - 3} = \frac{9}{ - 3} \\ [/tex]

Simplification

[tex]d = - 3[/tex]

And we're done...

The answer of x^3+3^2-10x-30 is - 18

Considerando la definición de una ecuación, la edad actual de Claudia es 60 años.

Una ecuación es la igualdad existente entre dos expresiones algebraicas conectadas a través del signo de igualdad en la que figuran uno o varios valores desconocidos, llamadas incógnitas, además de ciertos datos conocidos.

Los miembros de una ecuación son cada una de las expresiones que aparecen a ambos lados del signo igual.

En este caso, "dentro de 10 años Claudia tendrá el doble de la edad que  tenía hace 25 años," puede ser expresado mediante una ecuación, donde consideras que "x" es la incógnita, que representa la edad actual de Claudia.

Teniendo en cuenta que el doble de un número se calcula multiplicando el número por 2, entonces:

Entonces, la ecuación queda expresada como:

x+10=2(x-25)

Resolviendo:

x+10=2x-50

10 + 50= 2x - x

60= x

Finalmente, la edad actual de Claudia es 60 años.
