HELP PLEASE. which equation describes a line parallel to line g that has a y-intercept at (0, -1)

Work Shown:

x^2 - 9 = 0

x^2 - 3^2 = 0

(x-3)(x+3) = 0 ..... difference of squares rule

x-3=0 or x+3=0

x = 3 or x = -3

Answer:

FALSE

Step-by-step explanation:

We are assuming that t is a real number.

Thus, cos(t) is a real number greater than or equal to -1 and less than or equal to +1.  

Thus, cos(t) = 3 is false for all real t, and so in particular it is false for the value(s) of t such that tan(t) = 2/3.

Answer:

45m

Step-by-step explanation:

you have to find the diagonal by using the pitagora's theoreme.

it uses the formula [tex]\sqrt a^{2} +b^{2}[/tex] when you have to find the lenght of the longer side of a triangle with an angle of 90°. So the diagonal will be [tex]\sqrt27^{2} +36^{2}[/tex] =[tex]\sqrt729+1296[/tex] =  [tex]\sqrt2025[/tex] = 45

Answer:

-2 [tex]\frac{1}{2}[/tex] = -2.5 and 3[tex]\frac{1}{3}[/tex] = -3.33333333

Step-by-step explanation:

The cost of each 1 pound candy is $30, 1 box of cookies is $5 and 1 can of popcorn is $10.

We have the church youth group is selling snacks to raise money to attend their convention.

We have to determine the cost of each item they sold.

The mathematical equation representing the above statement is -

2x + 5y = 50

According to question -

Assume that the cost of :

1 pound candy = $x

1 box of cookies = $y

1 can of popcorn = $z

Now, write down the mathematical equation representing their total sales -

Amy -      2x + 3y + z = 85

Brian -     4x + 4y + 3z = 170

Paulina -     8x + 8y + 5z = 330

We will use the Cramer's rule to solve these equations -

The 3 x 3 coefficient matrix is -

[tex]\left[\begin{array}{ccc}2&3&1\\4&4&3\\8&8&5\end{array}\right][/tex]

Find its determinant -

D = 2(4 x 5 - 3 x 8) - 3(4 x 5 - 8 x 3) + 1(4 x 8 - 4 x 8) = 4

Create the X- matrix (X - matrix is formed by replacing the x-column values with the answer-column values) as follows -

[tex]\left[\begin{array}{ccc}85&3&1\\170&4&3\\330&8&5\end{array}\right][/tex]

Find th determinant of this X - matrix same as done above -

D(X) = 120

Similarly create a Y - matrix and Z - matrix and find their respective determinants. On solving you will get -

D(Y) = 20

D(Z) = 40

According to the Cramer's rule -

[tex]$x = \frac{D_{x} }{D}[/tex]

[tex]$y = \frac{D_{y} }{D}[/tex]

[tex]$z = \frac{D_{z} }{D}[/tex]

Therefore -

x = 120/4 = 30

y = 20/4 = 5

z = 40/4 = 10

Hence, the cost of each 1 pound candy is $30, 1 box of cookies is $5 and 1 can of popcorn is $10.

Answer: Option A.

Step-by-step explanation: Draw a number line from negative 5 to positive 5 with increments of 0.5. Make an empty circle on the first mark to the left of 0. It means mark an open circle at -0.5.

The region to the left of the empty circle is shaded. It means all the points lie on the left side of -0.5 at in the shaded region.

We need to find a statement that explains whether −1.5 can be a value in the shaded region.

Since −1.5 lies to the left of −0.5 , therefore -1.5 is in the shaded region.

Therefore, the correct option is A.
