The ratio of blue tacks to red tacks on the bulletin board is 3 to 5. there are 50 red tacks. how many blue tacks are on the boa
natulia [17]
3:5=x:50

Therefore 5 ×x = 50

x = 10

Therefore 3 × 10 = 30

therefore 30 blue pens

proof = 30 blue + 50 red= 3+ 5

therefore 80 = 8x

Please help, will give brainliest! :)
Sedbober [7]

Answer:

(2,2) , (0,0), (5,3)

Step-by-step explanation:

To check which points are solution to the system of inequalities, substitute the value of those points in the two inequalities and make sure are both true.

y ≤ x

y > -x +1

Point (x=2, y=2)

2 ≤ 2 ✅

2 > -2 +1 ⇒ 2 > -1 ✅

Because both inequalities are true using the coordinates of this point then the point IS a solution to the system of inequalities.

Point (x= -2, y=2)

2 ≤ -2 ❌

We stop checking because we need both inequalities to work. This point IS NOT a solution.  

Point (x=0, y=0)

0 ≤ 0 ✅

0 > -0 +1 ⇒ 2 > 1 ✅

This point IS a solution.

Point (x=0, y=5)

5 ≤ 2 ❌

This point IS NOT a solution.

Point (x=2, y= -2)

-2 ≤ 2 ✅

-2 > -2 +1 ⇒ -2 > -1 ❌

This point IS NOT a solution.

Point (x=5, y=3)

3 ≤ 5 ✅

3 > -5 +1 ⇒ 3 > -4 ✅

This point IS a solution.

Point (x=4, y= -3)

-3 ≤ 4 ✅

-3 > -4 +1 ⇒ -3 > -3 ❌

This point IS NOT a solution.

Point (x=-2, y=-2)

-2 ≤ -2 ✅

-2 > - -2 +1 ⇒ -2 > 2+1 ⇒ -2 >3 ❌

This point IS NOT a solution.

Please help me asap for brainlist its for final exams
kumpel [21]

Answer: y = —\frac{1}{2} x + 3

Step-by-step explanation:

The line crosses the y-axis at the point (0,3), making its y-intercept be +3.

The line is going downwards left to right, giving it a negative slope.

The line's slope is —\frac{1}{2} because it is negative and it goes down 1, over 2.

Therefore, the line's equation is    y = —\frac{1}{2} x + 3
