Answer:
m= 3 b= -2
Step-by-step explanation:
The formula is y=mx+b
Plugging in the numbers, we get y=3x-2. When we change the subtraction to addition, we get y=3x+ -2.
Therefore, your answers are m=3 and b= -2

Answer:
O 68, 14, 3
Step-by-step explanation:
Given:
f(x) = 4x² - x
When x = -4
f(x) = 4x² - x
= 4(-4)² - (-4)
= 4(16) + 4
= 64 + 4
f(x) = 68
When x = 1
f(x) = 4x² - x
= 4(1)² - 1
= 4(1) - 1
= 4 - 1
f(x) = 3
When x = 2
f(x) = 4x² - x
= 4(2)² - 2
= 4(4) - 2
= 16 - 2
f(x) = 14
The answer = 68, 3, 14
Answer:
861 : 615
Step-by-step explanation:
7 + 5 = 12
246 ÷ 12 = 123
7 × 123 = 861
5 × 123 = 615
861 -65 = 246
Answer:
B
Step-by-step explanation:
a^2+b^2=c^2
2^2+4^2=x^2
4+16=x^2
20=x^2
x=about 4.5
