Y+2=3(x-1)y=-2x+10 What is the solution to the system ( , )

Mathematics
1 answer:
disa [49]4 years ago
4 0

Answer:

(3, 4)

Step-by-step explanation:

y+2=3(x-1)y=-2x+10 should be written as y + 2 = 3(x - 1)      y = -2x + 10 or

y + 2 = 3(x - 1)      

y = -2x + 10

Let's eliminate y temporarily.  Substitute -2x + 10 for y in the first equation, obtaining:

-2x + 10 + 2 = 3x - 3

Now combine the x terms on the right and the constants on the left:

10 + 2 + 3 = 3x + 2x

so that

15 = 5x.  Then x must equal 3.  Using the second equation, we now find y by substituting 3 for x:  

y = -2(3) + 10, or y = 4

The solution to this system is (3, 4)

The difference between objects being "similar" vs. "congruent
bija089 [108]

Answer: See below

Step-by-step explanation:

The difference between similar and congruent is the size and shape.

If two objects are similar, they look similar to each other, meaning they look the same, but not exactly the same. It can be 2 stuffed animals that look the same, but different sizes. One can be large and other can be small.

If two objects are comgruent, you know that they are EXACTLY the same. They are the same size, shape, etc. Using the example from above, you have either two large stuffed animals, or two small stuffed animals. The two large animals would be congruent to each other, same for the small animals.

Marrrta [24]
111 straw bundles / 4 per stall = 27.75
However, you can’t technically have a .75 of a stall, so you round down to the nearest whole number, which is 27.

What is the value of the expression 9 − (fraction 1 over 2)4 ⋅ 48?<br><br> 1<br> 3<br> 6<br> 9
Hunter-Best [27]

Answer:

The answer is not in the list you gave.

Step-by-step explanation:

From what I understood, the problem is read 9 - (1/2)4 x 48. You would follow PEMDAS and start with the parentheses. 1/2 of 4 is 2. 2 multiplied by 48 is 96. 9 - 96 = -87. So maybe you misread the problem.
