P-x= -10
Now to isolate x divide both sides by p
-x = -10/p
But x can not be a negative do distribute a negative 1 to both sides and your answer is :
x = 10/p

P•x = - 10
so in conclusion

Given the equation sqrt(x+1)+3=0, explain how to and solve this equation. Is the solution extraneous? Explain​
Darina [25.2K]

√(<em>x</em> + 1) + 3 = 0   ==>   √(<em>x</em> + 1) = -3

has no real solutions, since the square root cannot be a negative number. But if we were to ignore that for the moment, one might try taking the square of both sides, which gives

(√(<em>x</em> + 1))² = (-3)²   ==>   <em>x</em> + 1 = 9   ==>   <em>x</em> = 8

But this is not a valid solution, since

√(8 + 1) = √9 = 3 ≠ -3

While -3 is a square root of 9, we had started off with the *positive* square root of <em>x</em> + 1.

In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on th
ddd [48]

Answer:

the weighted score is 82.03

Step-by-step explanation:

The computation of the weighted score is as follows

= Respective scores × respective test or exam and score

= 0.21 × 90 + 0.24 × 71 + 0.24 × 71 + 0.31 × 79

= 18.9 + 21.6 + 17.04 + 24.49

= 82.03

Hence, the weighted score is 82.03

We simply applied the above formula so that the weighted score could be come

1) If 6 jalapenos are used, how many anaheims will be used? (just numbers...no labels)​

By counting the table entries, we can see that there are 10 different options for a 3-topping pizza.

The different toppings ought on a pizza are:

As a general rule of thumb, I recommend selecting three to five toppings for each pizza you create.

Because mozzarella is a basic component of every pizza I prepare, it does not qualify as a topping.

Other cheeses that can be used as toppings are goat cheese, feta, and smoked gouda.

The most common supreme toppings are pepperoni, link, immature bell pepper, ebony olives, and red onions.

Sautéed mushrooms or even hot peppers are frequently incorporated.

Even though the sauce and cheese should almost always go on the bottom, the toppings themselves usually require the greatest attention.

Regardless of how many layers your pizza has, the top layer will receive the most heat.

Thus, by counting the table entries, we can see that there are 10 different options for a 3-topping pizza.

Use linear combination to solve this problem. show your work.<br><br> 3x + 2y = -4<br> 4x - y = 13
pshichka [43]

Answer:

The solution of the system of equations is the point (2,-5)

Step-by-step explanation:

we have

3x+2y=-4 -----> equation A

4x-y=13 -----> equation B

Multiply the equation B by 2 both sides

2*(4x-y)=2*13

8x-2y=26 ------> equation C

Adds equation A and equation C

3x+2y=-4\\8x-2y=26\\----------\\3x+8x=-4+26\\11x=22\\x=2

Find the value of y

Substitute the value of x in equation A

3(2)+2y=-4

2y=-4-6

y=-10/2=-5

The solution of the system of equations is the point (2,-5)
