Graph the following system of inequalities.
Answer:
X i think
Step-by-step explanation:
In order to determine if ratios are in proportion, we need to check if the cross products of the ratios are equal. Parts a and b are in proportion, while part c is not.
In order for ratios to be in proportion, the cross products of the ratios must be equal. Let's check the ratios given:
a) 5/25 = 1/5 and 6/30 = 1/5, so these ratios are in proportion.
b) 15/40 = 3/8 and 3/8 = 3/8, so these ratios are in proportion.
c) 8/15 ≠ 5/9, so these ratios are not in proportion.
Therefore, the ratios in parts a and b are in proportion.

Answer:
<2, <5, and <7.
Step-by-step explanation:
<2 and 72°, are vertical angles. Vertical angles are congruent. Therefore, <2 ≅ 72°.
<7 and 72° are corresponding angles. Corresponding angles are congruent, therefore, <7 ≅ 72°.
<5 and 72° are alternate interior angles. Alternate interior angles are congruent, therefore, <5 ≅ 72°.
Angles that are congruent to 72° are <2, <5, and <7.
