MatroZZZ [7]

Answer:

y-coordinate= 4

Step-by-step explanation:

y+2= -3( x-4) Solve for y

y= -3( x-4) -2

y= -3x +12 -2

y= -3x +10

Now in the given ( _, -2) x=-2

Substitute x= -2 to find the matching y value.

y= -3x +10

y= -3(2) +10

y= -6 +10

y=4

Given y+2= -3( x-4) the missing blank is (4, -2)

anna has 300naira and ojo has 1860naira.if anna saves 50 naira a day and ojo spends 70 a day, after how many days will they have
ExtremeBDS [4]

Answer:

Anna and Ojo will have same amount after 13 days.

Step-by-step explanation:

Given that:

Anna has 300 naira

She saves 50 naira per day.

Let,

x be the number of days.

y be the amount saved

y = 50x + 300

Ojo has 1860 naira

He spends 70 naira per day.

Let,

x be the number of days

y be the amount left

y = 1860 - 70x

For equal amount, the equations will be equal

50x +300 = 1860 - 70x

50x + 70x = 1860 - 300

120x = 1560

Dividing both sides by 120

\frac{120x}{120}=\frac{1560}{120}\\x=13

Hence,

Anna and Ojo will have same amount after 13 days.

What is the next term in the pattern? 3, 6, 9, 12, _________ What is the next term in the pattern? 48, 24, 12, 6, ________ What
TEA [102]

Answer:

The next in the first pattern is 15.

The next in the second pattern would be 3.

The next in the third pattern would be 32.

Step-by-step explanation:

In the first pattern, you can notice that the terms keep going up by 3. As a result, the next one is 3 higher (12 + 3 = 15)

In the second pattern, the next number is always half of the number before it. (6 * 1/2 = 3)

The last pattern shows each number being 10 less than the one before it. (42 - 10 = 32)
