Y = 2x + 3 - it's a linear function

for x = 0 → y = 2 · 0 + 3 = 3 ⇒ A(0; 3)

for x = -2 → y = 2 · (-2) + 3 = -4 + 3 = -1 ⇒ B(-2;-1)

Look at the picture.

Nicholas wrote the steps below to simplify the fraction 20/30 find his error and correct it
Dmitrij [34]
Unfortunately, Nicholas' steps in simplifying the fraction is not reflected in the question. However, the general idea of the simplifying fraction is to find the greatest common factor (GCF) of both the numerator and the denominator. In this case, the GCF is 10. Then, divide both numbers by the GCF. The answer for this item should be 2/3.

Answer accordingly. ........................

Answer:

36

Step-by-step explanation:

the pattern is adding the number to every whole number less than it. So if the start was 8, it would go 8+7+6+5+4+3+2+1, which is 36

If the sides of a triangle are in the ratio 3:4:5, prove that it is<br>right-angled triangle​
lyudmila [28]

Answer:

hope this helps

Step-by-step explanation:

Let a , b , c are three sides of a triangle

a : b : c = 3 : 4 : 5

a = 3x ,

b = 4x ,

c = 5x

a² = 9x²

b² = 16x²,

c² = 25x².

c² = a² + b²

by the pythagorean theorem,

a , b , c forms a right angled Triangle.
