Step-by-step explanation:
find the equation of the straight line passing through P -2,1and parallel to the line with equation 2x - 3y=1
Answer:
[tex]y=\frac{2}{3} x+\frac{7}{3}[/tex]
Step-by-step explanation:
Parallel lines have the same slope. Therefore, the line we're trying to find the equation for and the given line 2x-3y=1 must have the same slope.
1) Find the slope of 2x-3y=1
To do this, rewrite this equation in slope-intercept form: [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept (the value of y when the line crosses the y-axis)
[tex]2x-3y=1[/tex]
Subtract 2x from both sides
[tex]2x-3y-2x=1-2x\\-3y=-2x+1[/tex]
Divide both sides by -3 to isolate y
[tex]\frac{-3y}{-3}=\frac{-2}{-3}x+(\frac{1}{-3} )\\y=\frac{2}{3}x-\frac{1}{3}[/tex]
Now, we can easily identify that [tex]\frac{2}{3}[/tex] is in the position of m, the slope. Plug this into [tex]y=mx+b[/tex]:
[tex]y=\frac{2}{3} x+b[/tex]
2) Find the y-intercept
[tex]y=\frac{2}{3} x+b[/tex]
To find the y-intercept, plug the given point P(-2,1) into the equation and solve for b
[tex]1=\frac{2}{3} (-2)+b\\1=\frac{-4}{3}+b[/tex]
Add [tex]\frac{4}{3}[/tex] to both sides of the equation
[tex]1+\frac{4}{3}= \frac{-4}{3} +b+\frac{4}{3} \\\frac{3}{3} +\frac{4}{3}= b\\\frac{7}{3}[/tex]
Therefore, the y-intercept of the line is [tex]\frac{7}{3}[/tex]. Plug this into our original equation:
[tex]y=\frac{2}{3} x+b\\y=\frac{2}{3} x+\frac{7}{3}[/tex]

Caleb is designing a new board game, and is trying to figure out all the possible outcomes. How many different possible outcomes are there if he flips a coin and spins a spinner with three equal-sized sections labeled Walk, Run, Stop?
Answer:
6
Step-by-step explanation:
number of ways to flip coin-2
number of ways to spin the spinner-3
2*3=6
6 different possible outcomes are there if he flips a coin and spins a spinner with three equal-sized sections.
What is Combination?A combination is a mathematical technique for determining the number of potential arrangements in a set of objects where the order of the selection is irrelevant. You can choose the components in any order in combinations. Permutations and combinations are often mistaken.
Caleb is designing a new board game, and is trying to figure out all the possible outcomes.
Outcome of Flipping a coin = 2 (Head or Tail)
and, Spinner had three equal sized section.
So, the number of possible outcomes
= 2 x 3
= 6
Thus, there 6 outcomes.

1. Find the angle between the vectors:
i-23 + 5k and 3i+j - 2k
Answer:
The angle between the two vectors
∝ = 64°
Step-by-step explanation:
Step(i):-
Given that the vectors
[tex]a^{-} = i^{-} - 2j^{-} +5k^{-}[/tex]
and
[tex]b^{-} = 3i^{-} +j^{-} -2k^{-}[/tex]
[tex](a^{-} . b^{-} ) = (i^{-} - 2j^{-} +5k^{-} ) . (3 i^{-} + j^{-} - 2k^{-} )[/tex]
= 3 (i⁻ . i⁻) - 2(j⁻.j⁻) -10(k⁻.k⁻)
= 3 - 2 -10
= -9
Step(ii):-
Let '∝' be the angle between the two vectors
[tex]cos\alpha = \frac{a^{-}.b^{-} }{|a||b|}[/tex]
[tex]cos\alpha = \frac{|-9| }{\sqrt{1+4+25}\sqrt{9+1+4} }[/tex]
[tex]cos\alpha = \frac{|-9| }{\sqrt{30}\sqrt{14} }[/tex]
[tex]\alpha =cos^{-1} ( \frac{|-9| }{\sqrt{30}\sqrt{14} })[/tex]
∝ = cos⁻¹(0.4392) = 63.947
Final answer:-
The angle between the two vectors
∝ = cos⁻¹(0.4392) = 63.947
∝ = 64°

This line plot shows the daily rainfall amounts during the month of May.
On June 1, the rainfall amount was 1/2 of the greatest daily rainfall that fell in May.
What was the rainfall amount on June 1?
Enter your answer in the box as a fraction in simplest form.
Answer:
Rainfall amount on June 1 = ¾ inch
Step-by-step explanation:
Greatest daily rainfall in May = 1½
Rainfall amount in June 1 = ½ of 1½
Thus:
rainfall amount in June = ½ × 1½
= ½ × ³/2
= (1*3)/(2*2)
= ¾
Rainfall amount on June 1 = ¾ inch

The way you solve this is you transform it until one side of the equation is just "y"
3y + 2 = 8 ; subtract 2 from both sides
3y = 6 ; divide both sides by 3
y = 2
What is the other shape in the composite figure besides the rectangular prism?
triangular pyramid
square pyramid
triangular prism
cube
Answer:
cube
Step-by-step explanation:
The shape in the middle of the two rectangular prism would be a cube. This is the case since the angle at the base of the rectanglular prism forms a 90-degree angle. This indicates that the line is a straight line and would also form a 90-degree angle with the bottom angles as well. This would ultimately indicate that it forms a square, and since the shape is a 3-Dimensional shape it would be classified as a cube in this image.
Answer:
Triangular Prism
Step-by-step explanation:
The middle shape is a rectangular prism.
The top and bottom is a Triangular Prism.

For Tammy's wedding she wants to
purchase $80 flower centerpieces to put on
tables. The flower shop will also charge her
$35 for delivering the centerpieces. If Tammy
has a budget of $1000 to decorate the tables,
how many centerpieces can she buy?
Answer:
She can only buy 12 centerpieces.
Step-by-step explanation:
To solve this question, we must first create an expression. We know that the total would be $1000. The delivery is included in that budget and it is a constant. EACH centerpiece is $80. From that information, you can build an expression.
80c + 35 = 1000
-------------------------------------
Next, you will need to solve for c, or any variable you choose. If you solve it, you will be left with:
c= 12.06
--------------------------------------
Since you cannot buy a fraction of a centerpiece, this concludes that the answer would be 12.
Good Luck!!

A rectangle has a length of 5 cm and a
width of 4 cm. Every dimension is
tripled to form a second rectangle.
What is the ratio of the areas of the two
rectangles?
Answer:
1:9
Step-by-step explanation:
First Rectangle:
width x height = area
4 * 5 = 20
Second Rectangle:
(4*3)*(5*3)=x
12 * 15 = 180
Ratio:
180/20 = 90
1:9
Answer:
1:9 or 1/9
Step-by-step explanation:
if a rectangle is 5cm × 4cm
Area of rectangle= length ×width
= 5 × 4
=20cm²
if we triple dimensions of a rectangle we get the second rectangle
therefore, (5×3)cm × (4×3)cm
Area of second rectangle= 12 ×15
=180cm²
ratio is 20/180= 1/9 (Ans.)
