5 0

Answer:

No

Step-by-step explanation:

Substitute -4 for x and 2 for y in 4x+5y≤−7.  Is the resulting inequality true or not?

4(-4) + 5(2) ≤ −7

or

-16 + 10 ≤ −7, or

-6 ≤ −7, which is False.  No, (-4, 2) is not a solution of 4x + 5y ≤ −7.

Here are two patterns made using identical rhombuses. Write one equation to show how to find the value of ​a​ and one equation t
algol13

Answer:

Equation 1​

6*a = 360°

Equation 2

2*a + 2*b = 360°

a = 60°

b = 120°

Step-by-step explanation:

From the first picture we can see that 6 angles a° made a complete circle, that is, 360°. So:

6*a = 360°

a = 360°/6 = 60°

From the second picture we can see that 2 angles a° and 2 angles b° made a complete circle, then:

2*a + 2*b = 360°

2*b = 360° - 2*60°

b = 240°/2 = 120°
