Answer:
C. Yes, because the number of x - values is the same as the number of y-values
Answer:
The length of BC = 28 units
Step-by-step explanation:
* In triangle ABC
∵ Angles B and C are congruent
∴ m∠B = m∠C
* In any triangle if two angles are equal in measure, then the triangle is isosceles means the two sides which opposite to the congruent angles are equal in length
∴ AB = AC
∵ AB = 4x - 7
∵ AC = 2x + 7
∴ 4x - 7 = 2x + 7 ⇒ collect like terms
∴ 4x - 2x = 7 + 7
∴ 2x = 14 ⇒ divide both sides by 2
∴ x = 14 ÷ 2 = 7
* Now we can find the length of BC
∵ The length of BC = 4x ⇒ substitute the value of x
∴ The length of BC = 4 × 7 = 28 units
Answer:
Step-by-step explanation:
y - 5 = 1/2(x - 4)
y - 5 = 1/2x - 2
y = 1/2x + 3

Step-by-step explanation:
√(2/5) has a radical in the denominator. We want to eliminate that radical. To do this, multiply both √2 and √5 by √5:
√2·√5
