Solve -1/2w-3/5=1/5w

1 answer:

8 0

Very easy:

Common denominator:
-5/10w - 3/5 = 2/10w

- 3/5 = 7/10w

-30 = 35w

-30/35 = w

-6/7 = w

That's how you do it mate ;)

Struggling, can anyone help me out on these three functions? It would be much appreciated. Thanks so much!! :)

Maurinko [17]

Answer:

1. a) Not function

b) Domain is all real numbers greater than or equal 2 (x ≥ 2)

c) The range all real numbers ( -∞ < y < ∞)

2. a) Function

b) The domain is all real numbers (-∞ < x < ∞)

c) The range is all real number greater than or equal -4 (y ≥ -4)

3. a) Not function

b) domain is {-3 , -2 , -1 , 0 , 1 , 3}

c) The range is {-2 , -1 , 1 , 2 , 3 , 5}

Step-by-step explanation:

1. Not a function because some x has more than one corresponding y

Note: If we draw vertical line and move it left and right over the curve it will cut the cure in more than one point that means one x has more than one y

2. Function because every x has one corresponding y

3. Not function because some x have more than one corresponding y like

(-3 , -2) (-3 , 2) and (3 , -1) (3 , 2)

M∠JKP=67° m ∠ J K P = 67 ° what is the measure of m < PKL?

Lesechka [4]

The measure of m<PKL is 23 degrees

From the diagram attached, we can see that m∠JKP and m∠PKL are complementary, that is:

m∠JKP + m∠PKL = 90

Given the following

m<JKP = 67degrees

Get the measure of m<PKL

m<PKL = 90 - 67

m<PKL = 23 degrees

Hence the measure of m<PKL is 23 degrees

Find the radius of the circle if the center is at (1,2) and the point (-5,-6) lies on the circle

Tju [1.3M]

Answer:

sqrt{52}=r

Step-by-step explanation:

The equation of a circle has the following form:

where (h,k) is the center of a circle with radius r.

Our equation is:

We will find the radius by inputting the point (-5,6) which lies on the circle and solving for r.

28 students travel on a field trip. They bring a van that can seat 12 students. Elena and Kiran's teacher asks other adults to d

Valentin [98]

Answer:

Step-by-step explanation:

Yes, she can use this inequality and it does matter since the number of cars that the inequality provides will need to be equal to or more than that number in order for all the students to be able to go. Therefore, if we apply the inequality it would give us the minimum number of cars needed (n) like so

12 + 3n > 28 ... subtract 12 on both sides

3n > 16 ... divide both sides by 3

n > 5 1/3

Since there can't be 1/3 of a car and the number of cars needed must be higher than 5 1/3 then we would need a total of 6 cars to take all of the children.

HELP PLEASE I WILL GIVE BRAINLIEST

Andrei [34K]

Answer:

The slope intercept form is y = mx + b, where b is the y-intercept. In the equation y = 2x - 1, the y-intercept is -1. So, if you have an equation like y = 4x, there is no "b" term. Therefore, the y-intercept is zero, and the line passes through
