The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

The coordinates that we can plot on the graph are:

(1, -1/2), (2, 0), (3, 1/2), and (4, 1)

The graph is given below

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

We have,

The equation of a line y = (1/2)x - 1

We will find some coordinates from the equation.

When x = 1,

y = 1/2 - 1

y = -1/2

When x = 2,

y = 1/2 x 2 - 1

y = 1 - 1 = 0

When x  = 3,

y = 1/2 x 3 - 1

y = 3/2 - 1

y = 1/2

When x = 4.

y = 4/2 - 1

y = 2 - 1

y = 1

The coordinates that we can plot on the graph are:

(1, -1/2), (2, 0), (3, 1/2), and (4, 1)

The graph is given below

Thus,

The coordinates that we can plot on the graph are:

Answer:

7x - 3y = -12

Step-by-step explanation:

5(0-1) + 3y = 7(x + 1)

using BODMAS to solve

5(-1) + 3y = 7(x + 1)

-5 + 3y = 7x + 7

7x - 3y = -5 - 7

7x - 3y = -12

Answer:

D) 132

Step-by-step explanation:

y + 3x  =  180    {Co interior angles}

        y = 180 - 3x    ------------(I)

7x + 20 = y       {Vertically opposite angles}

7x + 20 = 180 - 3x   {From equation (I)}

7x + 3x +20 = 180

       10x + 20 = 180

            10x  = 180 -20

              10x = 160

                 x = 160/10

                x = 16

Plug in x = 16 in equation (I)

y = 180 - 3x

  = 180 - 3*16

  = 180 - 48

y = 132

Answer:

Dalisay

Step-by-step explanation:

3/5=0.6 (Kendra)

5/7≈ 0.75 (Dalisay)

5/7>3/5, so Dalisay hits the target more.

The probability of Dalisay hitting the target is more.

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

According to the given problem,

Kendra hits target 3 times for 5 misses

Probability = [tex]\frac{3}{5}[/tex]

                  = 0.6

Dalisay hits target 5 times for every 7 misses

Probability = [tex]\frac{5}{7}[/tex]

                  = 0.71

Hence, we can conclude that Dalisay hits the target more.

Answer:

48'11'' or 587''

Step-by-step explanation:

First convert to inches

5ft= 12 times 5 = 60 then plus 6=66in.= Jen's height

The ratio of the Jen height to Jen's shadow heightis 5'6'' : 9' which is equal to 66in.:108in.

To find the ratio we do 108/66 = 1.636...

Then we do 80' which is equal to 960"

Lastly we do 960/1.636... to get 586.797in for the height of the tree

48'11'' or 587''

Answer:

y + 4 = - (x - 5)

Step-by-step explanation:

The equation of a line in slope- intercept form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

Here m = - 1 and (a, b) = (5, - 4) , then

y - (- 4) = - 1 (x - 5) , that is

y + 4 = - (x - 5)

Answer:

[tex]y+4=-(x-5)[/tex]

Step-by-step explanation:

Point-slope form equation is written as:

[tex]y-y_1=m(x-x_1)[/tex]

where m is the slope and [tex](x_1,y_1)[/tex] is the point which the line passes through  so to to find the equation of line which passes through the point

(5 , -4) it means the point should satisfy the equation which furthermore means that the point lies on the lie so we can replace y1 with -4 and x1 with 5 and since we have m = -1 we can thus find b and rewrite the equation like this:

[tex]y-y_1=m(x-x1)\\y-(-4)=-1(x-5)\\y+4=-x+5[/tex]

since we need it point-slope form we leave it like this

[tex]y+4=-(x-5)[/tex]

Answer:

The band must sell at least 113 tickets to make a net profit of at least $ 1,925.

Step-by-step explanation:

While the band charges $ 25 for each entrance ticket to their performances, and the venue charges them $ 900 for the use of the place, the number of tickets that must be sold for the band to obtain a profit of at least $ 1,925 arises from the following calculation:

1,925 + 900 = Costs plus profit

2,825 / 25 = Number of tickets needed to cover costs and profit

113 = Number of tickets needed to cover costs and profit.

Therefore, the band must sell at least 113 tickets to make a net profit of at least $ 1,925.

Answer:

D.

Step-by-step equation:

I don't know but i think this is the answer.

The roots of the equation are x = 0.5205 and x = -0.8538. These roots are real, rational and unequal, thus option (B) is the correct answer.

A quadratic equation is a polynomial which has the highest degree equal to two. It is a second-degree equation of the form ax² + bx + c = 0, where a, b, are the coefficients, c is the constant term, and x is the variable.

For the given situation,

The equation is 9x^2 + 3x – 4 = 0

The roots of the equation can be found by the formula,

[tex]x=\frac{-b+\sqrt{b^{2}-4ac } }{2a}[/tex] or [tex]x=\frac{-b-\sqrt{b^{2}-4ac } }{2a}[/tex]

here, a = 9, b = 3 and c = -4

Substitute the above values,

⇒ [tex]x=\frac{-3+\sqrt{3^{2}-4(9)(-4) } }{2(9)}[/tex] or  [tex]x=\frac{-3-\sqrt{3^{2}-4(9)(-4) } }{2(9)}[/tex]

⇒ [tex]x=\frac{-3+\sqrt{9+144 } }{18}[/tex]          or  [tex]x=\frac{-3-\sqrt{9+144 } }{18}[/tex]

⇒ [tex]x=\frac{-3+\sqrt{153 } }{18}[/tex]             or  [tex]x=\frac{-3-\sqrt{153 } }{18}[/tex]

⇒ [tex]x=\frac{-3+12.36 }{18}[/tex]             or  [tex]x=\frac{-3-12.36 }{18}[/tex]

⇒ [tex]x=\frac{9.37}{18}[/tex]                    or  [tex]x=\frac{-15.37}{18}[/tex]

⇒ [tex]x=0.5205[/tex]                or  [tex]x=-0.8538[/tex]

Hence we can conclude that the roots of the equation are x = 0.5205 and x = -0.8538. These roots are real, rational and unequal, thus option (B) is the correct answer.

We need to solve the expression: [tex]\frac{2}{5}K-3\frac{1}{2}K =15[/tex] and find value of k

Solving:

[tex]\frac{2}{5}K-3\frac{1}{2}K =15[/tex]

She added incorrectly

Step-by-step explanation:

Answer should be (22, -26) but Kelcy got wrong because she has taken -1 in third step instead of taking 1 because -4 +5 is 1.

A vector is a quantity or phenomenon that has two independent properties: magnitude and direction.

Let  u = ⟨9, –2⟩, v = ⟨–4, 3⟩, and w = ⟨5, 1⟩

3u – 5(v + w)

3(9, -2)-5(⟨–4, 3⟩+⟨5, 1⟩)

Multiply 3 to (9, -2) and add v and w

(27,-6)-5(1,4)

(27, -6)-(5, 20)

Subtract the vectors

(27-5, -6-20)

(22, -26)

The answer should be (22, -26) but Kelcy got wrong because she has taken -1 in third step instead f taking 1 because -4 +5 is 1.

Hence,  answer should be (22, -26) but Kelcy got wrong because she has taken -1 in third step instead f taking 1 because -4 +5 is 1.
