3. Find the slope of the line that passes through (8, 1) and (3, 2). *
Answer:
your learning about slopes too :(
Step-by-step explanation:
Slope = change in y over change in x.
Slope = (2-1) / (3-8) = 1/-5 = -1/5
The answer is -1/5
A cookie delivery company charges $0.90 per cookie plus a $3 delivery fee. If an
order costs $11.10, how many cookies were ordered?
Answer:
9 cookies
Step-by-step explanation:
The equation is 11.1 = 0.9x + 3. First, we need to isolate the variable so we subtract 3 from both sides. 8.1 = 0.9x. Next we divide both sides by 0.9 which gives us 9 = x or x = 9.
4y-4x=16
slope intercept form
Answer:
y = x + 4
Step-by-step explanation:
Slope intercept form, y = mx + b, y = x + 4
Write an equation of the line that passes through (1,5) and is parallel to the line y=-4x+2.
9514 1404 393
Answer:
y = -4x +9
Step-by-step explanation:
The same slope-intercept equation can be used, but with a different y-intercept. That new y-intercept can be found from the given point (x, y) using the formula ...
b = y -mx
b = 5 -(-4)(1) = 9
So, the equation with the new y-intercept is ...
y = -4x +9

The length of the rectangular field is two times its breadth. If the perimeter of the field is 300m, find the length and breadth.
Answer:
Youu can call the breadth x and then, as the length is two times the breadth, it would be 2x.
So now when we call x to the breadth and 2x to the length we can do an equation, as we know the sum of the four sides is 300 meters, so
2x + 2x + x + x = 300
6x = 300
x = 300/6 = 50
We know that the breadth is 50m, and, the length, which is twice the breadth, would be 100m in this exercise.
SO in this case, the breadth is 50 meters and the length is 100 meters..
(40 POINTS) Let x = price of a standard ticket, y = price of a matinee ticket, and z = price of a senior ticket.
150x + 80y + 12z = 2,466
380x + 95y + 48z = 5,419
210x + 130y + 60z = 3,960
220x + 225y = 4,445
540x + 270y = 8,370 → y = −2x + 31
x = 11
The solutions to the system mean:
A.) Eleven tickets were sold on Friday. Nine tickets were sold on Saturday. Eight tickets were sold on Sunday.
B.) Eleven standard tickets were sold. Nine matinee tickets were sold. Eight senior tickets were sold.
C.) The price of a standard ticket is $11. The price of a matinee ticket is $9. The price of a senior ticket is $8.
Answer:
C. The price of a standard ticket is $11. The price of a matinee ticket is $9. The price of a senior ticket is $8.
Answer:
The answer is C

BE and CE are twoequal alltitudes of triangle ABC using RHS congurence rule prove that triangle ABC is isoloes
Answer:
The answer is below
Step-by-step explanation:
BE and CF are two equal altitudes of triangle ABC using RHS congruence rule prove that triangle ABC is isosceles.
Solution:
A triangle is a polygon with three sides and three angles. Types of triangles are right angled triangle, scalene triangle, equilateral triangle and isosceles triangle.
The RHS congruence rule states that if the hypotenuse and one leg of one triangle is equal to the hypotenuse and leg of another triangle; then the two triangles are equal. Two triangles are equal if they have three equal angles and three equal sides.
We have right angle triangles BEC and BFC
BE = CF (given)
CB = BC (both triangles have the same hypotenuse)
Hence ΔBEC = ΔBFC (RHS congruence rule)
Therefore; ∠BCE = ∠FBC (congruence theorem)
Since two angles of triangle ABC are equal (∠B = ∠C), therefore triangle ABC is an isosceles triangle and AB = AC

[tex] \frac{7}{9} \times \frac{5}{6} [/tex]
what is the answer to this?
Answer:
[tex]\frac{35}{54}[/tex]
Step-by-step explanation:
When multiplying two fractions, you multiply across always. We have two fractions :
7/9 and 5/6
So multiply across :
[tex]\frac{7 * 5}{9 * 6}[/tex]
[tex]\frac{35}{54}[/tex]

(e) A cable customer feels that the monthly cost of cable TV increased the most. A grocery customer feels that the cost of a dozen eggs increased the most. Is it possible for both customers to be correct? Explain your response in one or two complete sentences.
Answer and explanation:
Cable tv cost changed by $67-$55= $12= 12/55×100=21.818%
Cable TV cost increased by 21.818% of original cost
Dozen of eggs cost changed by $2.19-$1.79= $0.4= 0.4/1.79×100= 22.636%
Dozen of eggs cost increased by 22.636% of original cost
Therefore both customers can't be correct, cost of a dozen of eggs increased the most.

Bryan’s hockey team is purchasing jerseys. The company charges $250 for a one-time set-up fee and$23 for each printed jersey. Which expression represents the total cost of x number of jerseys for the team?
1) 23x
(2) 23x + 250
(3) 23 + 250x
(4) 23(x + 250)
Answer:
(2) 23x + 250
Step-by-step explanation:
We are given that
Company charges for one-time set up=$250
Charge for each printed jersey=$23
x=Number of jerseys for team
We have to find the expression which represents the total cost of x number of jerseys for the team.
Total cost of x jerseys printing=[tex]23\times x[/tex]
Total cost of x jerseys printing[tex]=23x[/tex]
Therefore,
Total cost of x number of jerseys for the team=250+23x
Hence, option (2) is true.
(2) 23x + 250
