Answer 1

Answer:

1) (i) dan (iii) karena gradiennya sama "4x"

2) gradien = 1/3

3) gradien = 4/7

4) y = 4/9x - 1/3

5) saya tidak tahu

6) (iii) dan (iv) karena gradiennya sama "3x"

7) y = 3x + 2

8) m = 2 c = -3

9) y = -2/3x + 3

10) g = -4/5

Step-by-step explanation:

1) i) y = 4x +10

ii) y = 2x +3

iii) y = 4x+5

iv) y =-2x +5

(i) dan (iii) karena gradiennya sama "4x"

2) g = (6-0)/(-2-0)

g = 6/-2

g =-3

m1 x m2 = -1

m2 = -1 / (-3)

m2 = 1/3 -----> gradien

3) A(0,0)

Hitung kotaknya

7 -----> Baik

4 -----> ke atas

gradient = 4/7

4) y = mx + c

1 = m(3) - 1/3

1 + (1/3) = m(3)

(4/3) / 3

m = 4/9

y = 4/9x - 1/3

5) saya tidak tahu

6) (iii) dan (iv) karena gradiennya sama "3x"

7) g = (6-3) / (-5-4)

g = -1/3

y - y1 = m (x -x1)

y - (3) = -1/3 (x - 4)

y = -1/3x + 4/3 + 3

y = -1/3x + 13/3

m1 x m2 = -1

m2 = -1 / (-1/3)

m2 = 3

y - y1 = m (x -x1)

y - (-4) = 3 (x - (-2))

y = 3x + 6 - 4

y = 3x + 2

8) g = (1-5) / (2-4)

g = 2

y - y1 = m (x - x1)

y - 5 = m (x - 4)

y = 2x - 8 + 5

y = 2x - 3

m = 2 c = -3

9) -2y = 12 - 3x

y = 3/2x - 6

m1 x m2 = -1

m2 = -1 / (3/2)

m2 = -2/3

y - y1 = m (x - x1)

y - (-1) = -2/3 (x - 6)

y = -2/3x + 4 -1

y = -2/3x + 3

10) g = (-20-0) / ( 0-(-25))

g = -4/5

Saya berharap jawaban saya membantu anda.

If y varies directly with x and y = 84 when x = 12, find y when x = 11.

Answers

Answer:

y= 77

Step-by-step explanation:

Write down the equation for direct proportion.

y= kx, where k is a constant.

Find the value of k.

When x= 12, y= 84,

84= k(12)

12k= 84

k= 84 ÷12

k= 7

Substitute the value of k into the equation.

y= 7x

When x=11,

y= 7(11)

y= 77

Moosa's sister is six years younger than 3 times his age. The sum of their ages is 30. How old is Moosa?

Answers

Suppose Moosa is ( x ) years old ,

Thus Moosa's sister is ( 3x - 6 ) years old .

The sum of their ages is 30 :

( x ) + ( 3x - 6 ) = 30 ==》 4x - 6 = 30

==》 4x = 36

1. Jemima wants to make chocolate chip walnut brownles. Chocolate chips come in a 12oz bag that costs $3. Walnuts
come in a 4oz bag that costs $2. If Jemima needs three pounds of chocolate chips and walnuts combined, and has $15
to spend, how many bags of each can she buy?

Answers

Answer:

4 bags of chocolate chips and 1 bag of walnuts.

Step-by-step explanation:

Find how many ounces are in 3 pounds:

16 oz = 1 lb

16 oz × 3 = 3 lbs

48 oz = 3 lbs

Variable x = number of chocolate chips

Variable y = number of walnuts

4x + 1y = 15

Keep in mind it must equal up to 48 oz and be $15 or under.

4 bags × 12 oz = 48 oz

1 bag × 4 oz = 4 oz

48 oz + 4 oz = 52 oz > 48 oz

4 bags × $3 = $12

1 bag × $2 = $2

$12 + $2 = $14 < $15

Both requirements have been met.

It takes you 3 hours to drive to a concert 135 miles away. You drive 55 miles per hour on highways and 40 miles per hour on the rest of the roads. Write a system of linear equations that represents this equation. Use x to represent the number of hours driving on a highway and y to represent the number of hours driving on other roads.

Answers

Answer:

x + y = 3  (1)

55x + 40y = 135 (2)

Step-by-step explanation:

Since  x to represent the number of hours driving on a highway and y to represent the number of hours driving on other roads and the total time for driving is 3 hours,

x + y = 3  (1)

Also, You drive 55 miles per hour on highways and 40 miles per hour on the rest of the roads, the distance moved on highways is 55x and the distance moved on the rest of the roads is 40y (since distance = speed × time).

Since the total distance moved is 135 miles, we have

55x + 40y = 135 (2)

So, the system of linear equations that represent the situation is

x + y = 3  (1)

55x + 40y = 135 (2)

Savannah bought barn wood for $60 for 5 pieces. She spent $40 on materials to paint
and design the decorations. She sells each piece of wood for $25. What is her
profit/loss?

Answers

her profit per each wood is $5 so her total profit is $25

because
60 divided by 5 is 12, so each wood is 12 dollars
she spent 40 dollars on materials so 40 divided by 5 is 8, so she spent $20 on each piece of wood to paint it because 12(price of wood)+8(cost of materials per wood)= 20
and shes sells them for 25
so 25-20=5
5x5=25
so the answer is $25 profited

7x-y=19
2x-3y=19​

Answers

Answer:

2x + y = -2, x + 2y = 2

4x + y - 2z = 0, 2x+ 3z = 9 , -6x - 2y + z = 0

x + y = 4 , x - y = 2

Step-by-step explanation:

Answer:

x=2 and y=−5

Step-by-step explanation:

Let's solve your system by elimination.

7x−y=19;2x−3y=19

Multiply the first equation by -3,and multiply the second equation by 1.

−3(7x−y=19)

1(2x−3y=19)

Becomes:

−21x+3y=−57

2x−3y=19

Add these equations to eliminate y:

−19x=−38

Then solve−19x=−38for x:

−19x=−38

(Divide both sides by -19)

x=2

Now that we've found x let's plug it back in to solve for y.

Write down an original equation:

7x−y=19

Substitute2forxin7x−y=19:

(7)(2)−y=19

−y+14=19(Simplify both sides of the equation)

−y+14+−14=19+−14(Add -14 to both sides)

−y=5

y=-5
