Answer:

The correct answer is 5.

Step-by-step explanation:

When solving a mathematical operation, the correct thing is to separate in terms so as not to obtain an erroneous result.

The only signs that separate terms are addition and subtraction. <u>You cannot separate a term in a division or multiplication. </u>

If you had operation 6 + 4: 2 + 1 =

The right thing would be for you to separate in terms of addition. Look at the result:

6 + 2 + 1 = 9

And see what would have happened if we separated it in the division:

10: 2 + 1 =

5 + 1 = 6

The results obtained are different. Therefore, if we obtained 6, the operation would be wrong.

Now, we have the following expression:

x2 - 10xy + 3y + y2 - 1

And we must remember that <u>between each incognita and a number there is a sign of multiplication</u>, although we do not see it written.

Therefore, the correct terms would be the following:

-10xy

-1

Given this information, we can say that the number of terms in this expression is 5.

What value(s) of x will make each equation below true

Dahasolnce [82]

We need to solve for x. Let's try problem b:

$2x-6=3x+1-x-7$

Let us first combine line terms. 3x and -x as well as 1 and -7 can be combined. Let's do that:

$2x-6=2x-6$

Since this is true, your answer would be:

All real numbers

------------------------------------------------------------------

Let's solve for problem c:

$3x+1=43$

Let's isolate x, so subtract 1 from both sides:

$3x=42$

Since x can't have a coefficient, divide both sides by 3:

$\frac{3x}{3}=\frac{42}{3}$

$x=14$

So, only the value of 14 would make this equation true.

------------------------------------------------------------------

Let's try problem d:

$4x-1=4x+7$

Let's get our whole numbers on the right side. Add 1 to both sides:

$4x=4x+8$

Subtract 4x from the right side on both sides:

$0=8$

Since this is not true, your answer would be:

No solution

If you rotate the point (2, 3) 90 degrees counterclockwise about the origin, what is the image of the point?

AlexFokin [52]

Rotation counterclockwise 90 degrees has the rule

(x,y) -> (-y,x)

So the image is obtained, according to the rule,
(2,3) -> (-3,2)

Martha bought new fish for her home aquarium. She Bought 3 guppies and 2 platies for a total of 13.95.Find the price of a guppy

Crazy boy [7]

Bought the same number of Guppies and only Hank bought 2 additional Platies. Thus, let’s subtract the total of Hank and Martha
=> 18.33 – 13. 95 = 4.38
Thus, Hank paid an additional of 4.34 for 2 platies. Let’s divide to get the price of platies
=> 4.34 / 2 = = 2.19 (price of platies each.)
Let’s solve for price of guppies
=> 13.95 – 4.34 = 9.61
=> 9.61 / 3 = 3.20 (Price of guppies each.)
