Answer:
a). y = 3/2x - 3/4 b).-2/3 c).y = -2/3x + 3
Step-by-step explanation:
a). 6x – 4y = 3
-4y = -6x + 3
y = 3/2x - 3/4
- The slope is 3/2.
b). The slope of a perpendicular line would be the opposite: -2/3
c). y = -2/3x + b
-1 = -2/3(6) + b
-1 = -4 + b
3 = b
y = -2/3x + 3

Raisins were $700 for a measure, where as plums cost $900 a measure. David and Bruce
bought 50 measures and spent $41,000. How many measures of raisins did they
buy
Answer:
20 measures of raisins
Step-by-step explanation:
700 r + 900 p = 41000 ...... (1)
r + p = 50 ⇒ p = 50 - r ....... (2)
(2) ------> (1)
700 r + 900( 50 - r ) = 41 000
700 r - 900 r = 41000 - 45000
- 200 r = - 4000
r = 20 measures

Let the graph of g be a translation 4 units down followed by a reflection about the y-axis of the graph of f(x)=−3x +2
Write a rule for g.
Answer:
[tex]g(x)=f(-x)-4[/tex]
Step-by-step explanation:
Hi there!
We're given that [tex]f(x)=-3x +2[/tex].
g(x) is f(x) translated 4 units down. Subtract 4 from f(x):
[tex]g(x)=f(x)-4[/tex]
It is also reflected about the y-axis. This makes all values of x negative:
[tex]g(x)=f(-x)-4[/tex]

Step-by-step explanation:
At a particular restaurant, each slider has 225 calories and each chicken wing has 70 calories. A combination meal with sliders and chicken wings has a total of 7 sliders and chicken wings altogether and contains 1110 calories. Write a system of equations that could be used to determine the number of sliders in the combination meal and the number of chicken wings in the combination meal.
Answer:
The appropriate equation for the above mentioned conditon would be
x+y=7
225x+70y=1110
Step-by-step explanation:
As mentioned in the question the meals contain just two delicacies (i.e. sliders and chicken wings)
Let the number of Sliders be represented by “x”
Let Number of Chicken wings be represented as “y”
As given in the question the total number of sliders and chicken wings equals 7
Hence x + y =7… Equation 1
Further, it is mentioned that each slider carries worth 225 calories of energy and chicken wing carries 70 calories of energy. Total calorie of a meal which contains sliders and wings is 1110 calories.
Thus, Total energy carried by sliders individually = total sliders* energy carried by one slider= 225x
Similarly, Total energy carried by wings individually = total chicken wings* energy carried by one wing= 70y
Thus 225x+70y=1110

Ohio City Burgers charges $6.75 for a
burger plus $.75 for each additional
topping.
Write an equation to determine
how many toppings you can get
with a total of $10.
Answer: x = (10 - 6.75) ÷ 0.75
Step-by-step explanation:
x stands for the maximum number of toppings you can afford.
10 stands for the amount of money you have (10$).
6.75 is the amount of money spent on the Burger alone.
0.75 is the money spent on each topping with your remaining money.

Step-by-step explanation:
1.
a. Isosceles right triangle
a° = 180 - (90 + 20)
a° = 180 - 110 = 70
b. Isosceles acute triangle
a° = 180 - (70+70)
a° = 180 - 140 = 40
c. The three angles inside a triangle always add up to 180°
∠A = 180 - (70 + 60)
∠A = 180 - 130
∠A = 50
so a° = 180 - 50 = 130
d. Isosceles acute triangle
∠A = 180 - (65 + 65)
∠A = 180 - 130
∠A = 50
so a° = 180 - 50 = 130
e. The angles of a rectangle add up to 360°
a° = 360 - (100 + 95 + 70)
a° = 360 - 265
a° = 95
f. The angles of a rectangle add up to 360°
2a° = 360 - (70 + 60)
2a° = 360 - 130
2a° = 230
a° = 115
2.
a. Straight angle is 180°
180 - 141 = 39
so x° = 180 - (39 + 39)
x° = 180 - 78
x° = 102
b. The three angles inside a triangle always add up to 180°
180 - (40 + 60)
180 - 100 = 80
opposite angle
x° = 180 - (80 + 35)
x° = 180 - 115 = 65
c. The angles of a rectangle add up to 360°
(x + 20)° + x° = 360 - (90 + 90)
(x + 20)° + x° = 360 - 180
(x + 20)° + x° = 180
x° = 80

Find the missing angle values show work.complete sentence
A. Angle a = ____
b. angle b = ____
c. angle c = ____
d. angle d = ____
e. These angles together make a complete rotation/a circle.What do you get when you add all the angles together.What does this number have to do with a circle?
Answer:
Step-by-step explanation:
Angle a = 35°
Angle b = 40°
Angle c = 35°
Angle d = 70°
When you add all the angles together, you get 360°. This number has to do with a circle because 360° is the total number of degrees in a circle, half of a circle would be 180°.
Hope this helps!
Answer:
∠a = 35
∠b = 40
∠c = 35
∠d = 70
Step-by-step explanation:
∠b = 40 {Vertical angles are congruent}
∠d = 70 {Vertical angles are congruent}
∠1 = ∠ a
∠2 = ∠c
∠1 = ∠2
So, ∠1 =∠2 = ∠a = ∠c
70 + 40 + ∠a + ∠2 = 180 {Straight line angle}
110 + 2∠a = 180 {∠a =∠2}
2∠a = 180 - 110
∠a = 70/2
∠a = 35
∠1 =∠2 = ∠a = ∠c = 35
e) When we add all the angles, we get 360.

∠1 and ∠2 are complementary angles. m∠1 is 5y+32 and m∠2 is 7y-14. Find m∠2 & show your work.
it was deleted last time I posted it???
[tex]\\ \sf\longmapsto 5y+32+7y-14=90[/tex]
[tex]\\ \sf\longmapsto 12y+18=90[/tex]
[tex]\\ \sf\longmapsto 12y=72[/tex]
[tex]\\ \sf\longmapsto y=6[/tex]
m<2=7(6)-14=42-14=28[/tex]The required value of m∠2 would be 30 degrees when the value of y = 6 due to the given pair of angles being complementary.
What are complementary angles?The complementary angles are defined as when pairing of angles addition to 90° then they are called complementary angles.
We have been given that the pair of angles as
(5y + 32)° and (7y - 14)°
∵ ∠1 and ∠2 are complementary angles
Here, the pairing of angles sums up to 90° then they are called complementary angles.
So 5y + 32 + 7y - 14 = 90°
⇒ 12y + 18 = 90
⇒ 12y = 72
⇒ y = 6
So m∠2 = 7y - 14
Substitute the value of y = 6 in the above equation, and we get
So m∠2 = 7(6) - 14 = 42 -12 = 30
Therefore, the value of m∠2 would be 30 degrees when the value of y = 6.

Olivia wants to clean her mansion, so she decides to hire a cleaning company. Company Fabuloso charges an initial hiring fee of $50 plus $30 per hour. Company Clorox charges an initial fee of $70 plus $25 per hour. After how many hours will it cost the same for both companies?
Answer:
4hrs
Step-by-step explanation:
Fabuloso charges = 50 + 30x = 80
Clorux charges = 70+25x = 95
£15 difference =( 3 * 5 ) = 30-25 = 5 = 15/3
= 3hrs + 1st hour = 4hrs
Fabuloso charges = 50 + 30(4) = 80+90 = $170
Clorux charges = 70+25(4) = 95 + 75=$170
= 4hrs
