What does 3x+76 equal

1 answer:

3 0

That depends on the value of 'x', and if 'x' changes, then the value
of that expression immediately changes.

All you can say is that whatever 'x' is at this moment, that expression
is 76 more than triple the value of 'x'.

58. Graph the function y=x^2+3x-18. How many real roots does the function have?

Answer:

58. 2 real roots; see attached for a graph

59. -6, 3

Step-by-step explanation:

58. A graphing calculator graphs this easily. The graph is shown in the attachment. There are 2 x-intercepts, hence 2 real roots.

59. The x-intercepts are (-6, 0) and (3, 0), so the x-values x=-6 and x=3 satisfy the equation y = 0.

Which expression is equivalent to 3m – 6?

Schach [20]

The answer is b because if you multiply 3 with m you get 3m and since -2 is a negative when you multiply it, it becomes -6

(-5, 4), (8,-6) help me please.. I don't know anything about geometry

Tom [10]

Answer:

Distance= 16.4 units

Midpoint= (1½, -1)

Step-by-step explanation:

$\boxed{distance \: between \: 2 \: points = \sqrt{ {(x1 - x2)}^{2} + {(y1 - y2)}^{2} } }$

Distance between (-5, 4) and (8, -6)

$= \sqrt{ {( - 5 - 8)}^{2} + {[4 - ( - 6)]}^{2} }$

$= \sqrt{ {( - 13)}^{2} + (4 + 6) {}^{2} }$

$= \sqrt{169 + 10^{2} }$

$= \sqrt{169 + 100}$

$= \sqrt{269}$

= 16.4 units (3 s.f.)

$\boxed{midpoint = ( \frac{x1 + x2}{2} , \frac{y1 + y2}{2} )}$

Midpoint

$= ( \frac{8 - 5}{2} , \frac{ - 6 + 4}{2} )$

$= ( \frac{3}{2} , \frac{ - 2}{2} )$

$= ( 1\frac{1}{2} , - 1)$
