Answer:
y = 2x - 9
Step-by-step explanation:
y2 - y1 / x2 - x1
9 - (-1) / 9 - 4
10 / 5
= 2
y = 2x + b
-1 = 2(4) + b
-1 = 8 + b
-9 = b

What is the distance between the points X(-4,3) and Y(2, -7) rounded to the nearest tenth? show your work.
O 11.7 units
O 8.0 units
O 16.0 units
O 4.5 units
Answer:
11.7 units
Step-by-step explanation:
sq root(2--4)^2+(-7-3)^2
sq root(6)^2 + (-10)^2
sq root (36)+(100)
sq root 136
equals 11.66 which rounds up to 11.7
Beatrice has a rectangular swimming pool in her backyard. The dimensions are 16 feet by 8 feet. She decides to build a deck of uniform
width around the pool. Together the pool and the deck will have an area of 384 square feet.
a) write the expression to represent the length and the width of the swimming pool with the deck around it
b) find x, the width of the deck
Rose is fishing from a small boat. A fish swimming at the same depth as the hook at the end of her fishing line is 8 meters away from the hook.
The question is incomplete, as the depth of the hook isn't given in the question. However, using a proposed depth for the hook, we could give a stepwise solution to the exercise.
Answer:
Kindly check explanation
Step-by-step explanation:
If given a hook depth of 6 meters, and a distance of 8 m(fishing line from hook) at the the Same depth, then the distance between rose and the fish, x can be calculated, using the relation.
Hypotenus² = opposite² + adjacent²
(refer to attached picture)
x² = 6² + 8²
x² = 36 +. 64
x² = 100
x = sqrt(100)
x = 10 meters
You can use the actual depth value to obtain the actual solution to your question.

Each boy in a class has 11 pockets and each girl in the class has 13 pockets. How many boys and how many girls are in this class if all 21 students have a total of 251 pockets? Please answer ASAP and please no links.
Answer:
10 girls
11 boys
Step-by-step explanation:
set up a system of equations:
b represents boys, g represents girls
b+g=21 (since there is a total of 21 students)
11b+13g=251 (since each boy has 11 pockets, each girl has 13, total of 251)
i chose the method of substitution, so i solved the first equation to get
b=21-g
then i substitute 21-g for b in the second equation, and solve:
11(21-g)+13g=251
231-11g+13g=251
2g+231=251
2g=20
g=10
then, i solved for boys (by choosing the top equation and substituting 10 for g, since we now know that g=10)
b+g=21
b+10=21
b=11
so there are 10 girls and 11 boys in this class
There are 10 girls and 11 boys in the class.
What is an equation?"It is a statement which consists of equal symbol between two mathematical expressions."
What is system of equations?"It is a finite set of equations for which we find a common solution."
For given example,
Let 'x' be the number of girls and 'y' be the number of boys.
Each boy in a class has 11 pockets and each girl in the class has 13 pockets.
And in this class if all 21 students have a total of 251 pockets.
So, we have system of equations,
⇒ x + y =21 .......................(1)
⇒ 13x + 11y = 251 .......................(2)
From equation (1),
x = 21 - y ......................(3)
Substitute this value of 'x' in the equation (2),
⇒ 13(21 - y) + 11y = 251
⇒ 273 - 13y + 11y = 251
⇒ 273 -2y - 273 = 251 - 273
⇒ -2y = -22
⇒ y = -22 / -2
⇒ y = 11
This means, there are 11 boys in the class.
Substitute the value of 'y' in equation (3),
⇒ x = 21 - 11
⇒ x = 10
This means there are 10 girls in the class.
Therefore, there are 10 girls and 11 boys in the class.

Find the volume of the prism.
1.2 cm
1.8 cm
2 cm
2.3 cm
The volume is
cubic centimeters.
Answer:
Volume of prism = 6.3 cm³
Step-by-step explanation:
Given:
Dimensions of parallels line = 2.3 and 1.2 cm
Height of prism = 1.8 cm
Width of prism = 2 cm
Find:
Volume of prism
Computation:
Volume of prism = Area of base x Width
Volume of prism = [(1/2)(sum of parallels line)(Height)]Width
Volume of prism = [(1/2)(2.3 + 1.2)(1.8)]2
Volume of prism = [(1/2)(3.5)(1.8)]2
Volume of prism = [(3.5)(1.8)]
Volume of prism = 6.3 cm³

Answer:
a=10.8; c=4.3
Step-by-step explanation:
The sum of all the angles in a triangle is 180 degrees.
Two of the angles are given as 40 deg and 120 deg.
Subtract the measures of both from the sum to get the last angle:
180-40-120=20; ∠C=20°
Using Law of Sines: [tex]\frac{a}{sinA}=\frac{b}{sinB}=\frac{c}{sinC}[/tex]

The perimeter of a rectangle is 54cm. If the length of rectangle is 18cm,find its area
Answer:
162cm squared
Step-by-step explanation:
The perimeter of a rectangle can be calculated by length+length+width+width.
We know the length is 18, so our equation of finding the width is:
54-(18*2) divided by 2.
54-36=18.
18/2=9.
The area of a rectangle can be calculated by length * width. We already have the length, and now we have the width.
18*9=162

Complete the square to write each equation in vertex form. Then, state whether the vertex is a minimum or a maximum and give its coordinates.
Answer:
vertex form: y = (x + 1)² - 3 the vertex is minimum coordinates of the vertex: (-1, -3)Step-by-step explanation:
[tex]y=x^2+2x-2\\\\y=x^2+2x+1-1-2\\\\\bold{y=(x+1)^2-3}[/tex]
a = 1 > 0 ← it means the parabla opens up, so, the vertex is minimum
The vertex form is y = a(x - h)² + k, where (h, k) is the vertex
So, from y = (x + 1)² - 3 the vertex is: (-1, -3)
