Find the solution of this system of equations -7x-6y=59 and -8-6y=58

1 answer:

8 0

-7x - 6y = 59.....multiply by -1
-8x - 6y = 58
----------------
7x + 6y = -59 (result of multiplying by -1)
-8x - 6y = 58
---------------add
-x = -1
x = 1

-7x - 6y = 59
-7(1) - 6y = 59
-7 - 6y = 59
-6y = 59 + 7
-6y = 66
y = -66/6
y = -11

solution is (1,-11)

Answer:

C. 25/6 ft²

Step-by-step explanation:

Let's call the dimensions of Rectangle B x and y. Then ...

xy = 5 ft²

and

x² = 6 ft²

We want to find the value of y². Solving the first equation for y, then substituting for x², we have ...

y = (5 ft²)/x

y² = ((5 ft²)/x) = 25 ft⁴/x² = 25 ft⁴/(6 ft²)

y² = (25/6) ft² . . . . . . . matches choice C

Is 3x+4y=7 linear or nonlinear

Sloan [31]

Linear. It's in the form C= ax + by, so you back solve to get into the form you know is linear (y= mx + b). So using SADMEP (opposite of Pemdas) we can decide which order to solve for "Y=" in. 4y =7-3x. Y=((7-3X)/4). Y= 7/4 -3/4x. Y=-3/4x +7/4. Which is linear

Pooja's plant began sprouting 222 days before Pooja bought it, and she had it for 989898 days until it died. At its tallest, the

MakcuM [25]

Answer:

Step-by-step explanation:

Given:

function h(t) models the height of Pooja's plant (in cm) where

t is the number of days after she bought it.

Now we have to find about which number type is more appropriate for the domain of h.

That means what values can be taken by the variable "t".

As per the questions, t represents number of days not the hours so it will not be in decimal or fraction value. It can only use integer values for the number of days. like 1, 2, 3 ...,n

Now as the time is counted after she bought the plant then number of days will be positive.

Hence answer for the type of domain can be positive integers or you can say integers greater than or equal to 0.

THE NUMBER 1-10 ARE IN A BAG, YOU TAKE 2 OUT WITHOUT REPLACEMENT. WHAT IS THE PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME

ehidna [41]

Answer:

1 / 18

Step-by-step explanation:

PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME = Number of favorable outcome / Total number of outcomes

Favorable outcome = 1

Total number of outcome (1,2,3,4,5,6,7,8,9,10) = 10

PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME = 1 / 10

PROBABILITY OF DRAWING AN EVEN NUMBER THE SECOND TIME = Number of favorable outcome / Total number of outcomes

Favorable outcome (2,4,6,8,10) = 5

Total number of outcomes (1,2,3,4,5,6,8,9,10) = 9

PROBABILITY OF DRAWING AN EVEN NUMBER THE SECOND TIME = 5/9

PROBABILITY OF DRAWING THE NUMBER 7 THE FIRST TIME AND THEN DRAWING AN EVEN NUMBER = 1 / 10 * 5 / 9 = 1 / 18
