Mathematics
1 answer:
7nadin3 [17]3 years ago
8 0

Answer:

see explanation

Step-by-step explanation:

Given the 2 equations

2x - 3y = - 2 → (1)

4x + y = 24 → (2)

Multiplying (1) by - 2 and adding to (2) gives

- 4x + 6y = 4 → (3)

Add (2) and (3) term by term

(4x - 4x) + (y + 6y) = (24 + 4), that is

7y = 28 ( divide both sides by 7 )

y = 4

Substitute y = 4 into either of the 2 equations

Substituting y = 4 into (2)

4x + 4 = 24 ( subtract 4 from both sides )

4x = 20 ( divide both sides by 4 )

x = 5

Thus the answers x = 5 and y = 4 are the same as her first method

. One-fifth of the plants in a garden are grape tomato plants. Two-ninths of the plants in the garden are cherry tomato plants.
vodomira [7]

Answer:52

Step-by-step explanation:

Given

one-fifth of the plants in a garden are grape tomato plant

two-ninth of the plants in the garden are cherry tomato plants

Also there are 18 grape tomato and 20 cherry tomato plants.

Let Total plants be x

Then Grape tomato plants =\frac{x}{5}=18

x=90

thus there are total of 90 plants

also grape tomato+cherry tomato=18+20=38

Thus there are 90-38=52 remaining plants.

Determine if the lines are parallel, perpendicular or neither y=-3/2x-4 and y=2/3x-7
aliya0001 [1]

Answer:

<u>They are perpendicular</u>

Step-by-step explanation:

Perpendicular lines have slopes that are negated versions of the other or positive versions of the slope of the other. The slopes are also flipped.

Parallel lines have the same slope.

Neither is when the lines do not follow either of these definitions.

The slope of your two lines are -3/2 and 2/3. These slopes are flipped and the opposite negations of each other. <u>This means the lines are perpendicular.</u>

Find how X and y compare when log X = 6.6 and log y = 3.6
asambeis [7]

Answer

x = 3981071.7055

y  = 3981.0717

x > y

Step by step explanation

First let's find the value of x and y by taking anti - log.

log X = 6.6

X = log^ -1 (6.6)

X = 3981071.7055

Similarly,

log Y = 3.6

Y = log ^(-1) 3.6

Y = 3981.0717


Once we found the values of X and Y , we can easily compare them.

Here x > y

Hope you will understand the concept.

Thank you. :)
