Answer:
x=25
Step-by-step explanation:
5x-5+ 2x+10 =180
2x-5x = 10+5
3x= 15
x=5
5(5)-5+ 2(5) +10 =180
Answer:
y = 3x + 5
Step-by-step explanation:
The equation in slope- intercept form is
y = mx + c
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (- 2, - 1) and (x₂, y₂ ) = (2, 11) ← 2 ordered pairs from the table
m = = = 3, thus
y = 3x + c ← is the partial equation
To find c substitute any ordered pair from the table into the partial equation
Using (2, 11 ), then
11 = 6 + c ⇒ c = 11 - 6 = 5
y = 3x + 5 ← equation of linear function
Answer:
<h2>(2a+3b)² - (16c)² = (2a + 3b - 16c)×(2a + 3b + 16c)</h2>
Step-by-step explanation:
(2a+3b)² - (16c)² = [(2a+3b) - 16c]×[(2a+3b) + 16c]
= [2a + 3b - 16c]×[2a + 3b + 16c]
