Answer 1

Answer:

Answer:

the simplified expression is 108x

Step-by-step explanation:

4x(22+5)

you can remove the parenthesis by multiplying 4x by everything inside of them.

4x * 22 + 4x * 5

88x + 20x

108x

WILL GIVE BRAINLIEST ANSWER!!!!Which of the following points satisfies the inequality 2x - 3y < 1?

(-2,1)
(1/2, 0)
(2, -1)

Answers

Check first one:
2(-2)- 3(1) < 1
-4 -3 < 1
-7 < 1
This is true, let's check others, just to be sure
Check second one:
2(1/2) - 3(0) < 1
1 - 0 < 1
This is false
Check third one :
2(2)- 3(1) < 1
4- 3 < 1
This is false

So answer is (-2,1)

(-2,1) satisfies
2×-2-3×1=-7
-7<1

Find the mindpoint of ab a(-3,7) and b(-7,-6)

Answers

Answer:

Step-by-step explanation:

The midpoint of AB is (-5,1), if A(-3,8) and B(-7,-6). How to find out the midpoint of coordinates?The midpoint of coordinates is found by measuring the distance between two endpoints and dividing the obtained result by 2. Apart from this, one more method is there which is to add the two X-coordinates of the endpoints and divide them by 2. The same concept is applied to the Y-coordinates as well. According to the question, A = (-3,8) and B = (-7,-6). The formula is as follows:M(x,y) = ((x₁+x₂)/2 , (y₁+y₂)/2). Putting the above values in the mentioned formula, we get:M(x,y) = ((-3-7)/2 , (8-6)/2).

M(x,y) = (-5 , 1). Therefore, the midpoint of AB is (-5,1), if A(-3,8) and B(-7,-6).To learn more about the Midpoint of coordinates, refer to the link: brainly.com/question/28308761

At lunch, Kira eats either a burrito containing 490 milligrams of sodium or a peanut butter sandwich containing 700 milligrams of sodium. Her doctor told her to reduce her sodium to no more than 4,000 milligrams per week. Which inequality represents x, the number of microwave burritos, and y, the number of peanut butter sandwiches, she can eat each week?
490x + 700y < 4000 490x + 700y ≤ 4000 490x + 700y > 4000 490x + 700y ≥ 4000

Answers

If
x is the number of microwave burritos
y is the number of peanut butter sandwiches
4000 is the maximum allowable sodium intake

Then, the inequality is:
490x + 700 y ≤ 4000

The correct answer is the second option.
