Answers

Answer 1

Answer: Equation: (2x-5y) + (x+y)
Add x terms together: 2x + x=3x
Add y terms together: -5y + y=-4y
Simplify: 3x-4y

Final Answer: 3x-4y

Without graphing, determine the range of the function f(x) = 4|x+6|-5 overthe interval [-10,5].

Answers

Answer:

[-5,39]

Step-by-step explanation:

The vertex is at (-6,-5)

The interval is from -10 to 5 (inclusive of both endpoints...

Absolute function is open up because 4 is positive

I will plug in both endpoints now:

f(-10)=4|-10+6|-5 f(5)=4|5+6|-5

f(-10)=4(4)-5 f(5)=4(11)-5

f(-10)=11 f(5)=39

So the highest reached by f(5) which is 39 so our range will go up to 39 (inclusive)

11 is not the lowest reached, -5 is because our vertex was included within the domain

So the range is [-5,39]

Jon's weight loss for each week of the month is 4 lbs., 3.5 lbs. and 2 lbs. He gained 4.5 lbs. the last week. If Jon originally weighted 153 lbs., how much does he weigh now?

Answers

Answer:

148 lbs

Step-by-step explanation:

Given: Jon's weight loss for each week of the month is 4 lbs., 3.5 lbs. and 2 lbs. He gained 4.5 lbs. the last week.

To Find: If Jon originally weighted 153 lbs., how much does he weigh now

Solution:

Jon's original weight $=153$ $\text{lbs}$

Jon's weight loss in three successive weeks are $= 4$ $\text{lbs}$

$= 3.5$ $\text{lbs}$

$= 2$ $\text{lbs}$

Total weight loss in three weeks is $=4+3.5+2$ $\text{lbs}$

$=9.5$ $\text{lbs}$

Jon's weight after three weeks $=153-\text{weigth loss}$

$=153-9.5$

$143.5$ $\text{lbs}$

Gain in Jon's weight $= 4.5$ $\text{lbs}$

Jon's weight after 4 weeks $=143.5+\text{weight gain}$

$143.5+4.5$

$148$ $\text{lbs}$

Jon weighs $148$ $\text{lbs}$ now.

You have to add the weight he loss then subtract it from 153

-2p-4=2 please Help me

Answers

-2p - 4 = 2

Add 4 to each side: -2p = 6

Divide each side by 2 : -p = 3

Multiply each side by -1 : p = -3

To get the answer we have to obtain single p on the LHS.
-2p-4=2 /:-2 (divide both sides by -2)
p+2=-1 /-2 (subtract 2 both sides)
p=-3 - its the answer

How do you find the missing length in Pythagorean

Answers

If this pertains to the Pythagorean theorem, then the answer that you would most likely to end up with is by utilizing the equation a² + b² = c² where a and b are the legs of the triangle and c is the hypotenuse. The hypotenuse refer to the longest side of the triangle while the other two would be the legs of the triangle.

When solving for the missing length, just substitute the values given to their respective places in the equation. If a length of a leg is missing, then substitute the other leg's value to either a or b, then substitute the length of the hypotenuse to c. Then solve. Solving for the hypotenuse's length would be a lot easier than the legs.
