Answer: -18x+20
Step-by-step explanation:
5+(−3)(6x−5)
=5+(−3)(6x−5)
=5-18x+15
=-18x+20
Answer:
-44 feet deep
In other words: 44 feet below ground
Step-by-step explanation:
First we have to write out the equation that the problem creates for us.
-48 - 11 + 15
Next we just have to subtract and add:
-48-11 = -59
-59+15 = 44
There we go! That's our answer.
Factorise 4b² + 16b ⇒ 4b(b+4)
expand (a-1)(a-2) ⇒ a(a-2) - 1(a-2) ⇒ a² - 2a - 1a + 2 ⇒a² - 3a + 2
factorise x² + 8x + 7 ⇒(x + 1) (x + 7)
evaluate y⁶ / y² ⇒ y * y * y * y * y * y / y * y = y⁴
if x = -1 and y = 5, find z when z = x² + 2y² ;
z = -1² + 2(5²) ⇒ 1 + 2(25) ⇒1 + 50 = 51
Make x the subject: y = 4x - 3
y = 4x - 3
<u>+3 +3</u>
3 + y = 4x
<u>÷4 ÷4 </u>
(3+y)/4 = x
Answer:
Step-by-step explanation:
Slope formula= rise over run, or y2-y1 over x2-x1
y2=-4 y1=-18 x2=-7 x1=-7
-4-(-18)/-7-(7)
-22/-14 negative
