Answer:
[tex]y=2x+4[/tex]
Step-by-step explanation:
You can solve this two ways: insert the values into point-slope form and simplify to solve for y, converting it to slope-intercept form, or insert the values into slope-intercept form, solve for b, and insert b. We'll do both :)
Point-slope form:
[tex]y-y_{1}=m(x-x_{1})[/tex]
Where:
[tex]m[/tex] is the slope[tex]x_{1}[/tex] and [tex]y_{1}[/tex] are corresponding coordinate points [tex](x,y)[/tex]Insert the given values:
[tex]m=2\\\\(-5_{x_{1}},-6_{y_{1}})\\\\y-(-6)=2(x-(-5))\\\\y+6=2(x+5)[/tex]
Solve for y. Expand the right sie using the distributive property:
[tex]y+6=2(x)+2(5)\\\\y+6=2x+10[/tex]
Isolate the variable. Subtract 6 from both sides, canceling out the 6 on the left:
[tex]y+6-6=2x+10-6\\\\y=2x+4[/tex]
OR
Slope-intercept form:
[tex]y=mx+b[/tex]
Where:
[tex]m[/tex] is the slope[tex]b[/tex] is the y-intercept[tex]x[/tex] and [tex]y[/tex] are corresponding coordinate points [tex](x,y)[/tex]Insert the given values:
[tex]m=2\\\\(-5_{x},-6_{y})\\\\-6=2(-5)+b[/tex]
Simplify the multiplication:
[tex]-6=-10+b[/tex]
Solve for b. Add 10 to both sides, canceling out the 10 on the right:
[tex]-6+10=-10+10+b\\\\4=b[/tex]
The value of b is 4. Insert the appropriate information into the equation. When using slope-intercept form, you don't plug in the coordinate points:
[tex]y=2x+4[/tex]

Write the phrase "9 increased by a number x" as an algebraic expression
Answer:
9+x
Step-by-step explanation:
To write 9 increased by a number x, you need to know that when it says "increased by" it means adding.
So it is saying 9 is being added by x, or 9+x as an algebraic expression.
The phrase "9 increased by a number x" as an algebraic expression would be; 9+x
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Five friends attend a matinee movie and spend $8 per ticket. They also purchase a small bag of popcorn each. The friends spend a total of $62.50. Let x be the price of a small bag of popcorn.
Part A
Which equation represents the situation?
62.50 + 8x = 40
40 + 8x = 62.50
40 + 5x = 62.50
62.50 + 5x = 40
Part B
How much does each small bag of popcorn cost?
$
Answer:
Formula: (cost of ticket + cost of popcorn) * # of friends = total cost
Which would give us (8 + x) * 5 = 62.5
Solve for x.
8 + x = 12.5 {divide each side by 5}
x = 12.5 - 8
x = 4.5
Each small bag of popcorn costs $4.50.
hope this helps!
The equation representing the given situation is 40 + 5x = 62.50 and the price of a small bag of popcorn will be $ 4.5. Option C is correct.
What is the equation?An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.
It is given that, five buddies each pay $8 for a ticket to the matinee. Additionally, they each buy a little bag of popcorn. The pals spend $62.50 altogether.
Suppose x represent the price of a small bag of popcorn.
(cost of ticket + cost of popcorn) × number of friends = total cost
⇒ (8 + x) 5 = 62.5
Simplify the equation to obtain the value of x as
⇒ (8 + x) = 62.5/5
⇒ 8 + x = 12.5
⇒ x = 12.5 - 8
⇒ x = 4.5
Thus, the equation representing the given situation is 40 + 5x = 62.50 and the price of a small bag of popcorn will be $ 4.5. Option C is correct. Option C is correct.

4 painters can paint a room in 6 hours how long will it take 3 painters to paint the same room
Answer:
the answer is that it will take 3 panters 3.5 hours to pant that room
Step-by-step explanation:
The number of hours taken by the painter to paint the room will be 4.5 hours .
Given,
4 painters can paint a room in 6 hours .
Now according to the method of unitary,
If 4 painters can paint the room in 6 hours ,
Then
1 painter will paint the room in
6/4 hours
= 3/2 hours .
Now the number of painters are 3
So if 1 painter paints the room in 3/2 hours then,
3 painters will paint the room in
3*3/2
= 4.5 hours
Thus the number of hours required are 4.5 hours .

27x + 15y = ? (9x + ? y)
Please help! I don't understand!
Answer:
3;5
Step-by-step explanation:
One side of the equation is 27x + 15y, the number of the first blank times 9x needs to be 27x, so it has to be 3. And 3 times {blank} y needs to be 15y, so the second blank has to be 5.
Hope this helps! :)
Answer:
27x + 15y = 3(9x + 5y)
Step-by-step explanation:
27x + 15y = ?(9x + ?y)
3 times 9 = 27
so the first ? would be 3
27x + 15y = 3(9x + ?y)
15/3 = 5
so the 2nd ? would be 5
27x + 15y = 3(9x + 5y)
Simplify to check your work.
27x + 15y = 3(9x + 5y)
27x + 15y = 3(9x) + 3(5y)
27x + 15y = 27x + 15y

A pyramid has a square base with sides that measure 10cm and a height of 14cm. What is the slant height of the pyramid?
A)17.2 cm
B)14.9 cm
C)13.2 cm
D)12.1 cm
The solution is, the slant height of the pyramid is 14.9 meters.
What is Pythagorean theorem?Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a2 + b2 = c2.
here, we have,
we know that,
The slant height is the height of a triangle making up the base of the pyramid.
We can imagine a right triangle with one leg being a vertical line from the peak of the pyramid going down to the center of the base, and the other leg going from the center of the base to the center of one edge of the base.
And finally, the hypotenuse will join the ends of those 2 lines together and will also be the slant height of the pyramid.
Then we can easily use the Pythagorean theorem to determine the slant height.
So, S = sqrt((10/2)^2 + 14^2)
S = sqrt(5^2 + 14^2)
S = sqrt(25 + 196)
S = sqrt(221)
S = 14.9
So the slant height of the specified pyramid is 14.9 meters.
