True or False? Picture provided below

Mathematics
1 answer:
OLEGan [10]4 years ago
7 0

Answer:

The statement is true

Step-by-step explanation:

To answer this question we must take the limit of f(x) when the function tends to 1. We must take this limit by the right and the left of 0. (-1 ^{+}; -1 ^{-}). If any of these limits tends to infinity then the function is discontinuous at x = -1.

But if the

\lim_{x \to \\-1^+}f(x)=\lim_{x \to \\-1^-}f(x) = b      <em>Where b is a real number</em>

Then the function is continuous at x = -1

Then.

\lim_{x \to \\-1^+}f(x) = \lim_{x \to \\-1^+}-2x +1\\\\\lim_{x \to \\-1^+}-2(-1) +1 = 3

and

\lim_{x \to \\-1^-}f(x) = \lim_{x \to \\-1^-} 2x+5\\\\\lim_{x \to \\-1^-} 2(-1)+5 = 3

Then:

\lim_{x \to \\-1^+}f(x) = \lim_{x \to \\-1^-}f(x) = 3

Therefore the function is continuous at x = -1. The statement is true

What type of triangle has an exterior angle that is obtuse at two vertices? Explain your reasoning.​
navik [9.2K]

Answer:

A right triangle

Step-by-step explanation:

A right triangle would meet these characteristics. A triangle's inner angles always add up to be 180 degrees. A right triangle has one angle at 90 degrees meaning the other two angles need to be less than 90 degrees and sum up to be 90 degrees. This would indicate that both of these angles' exterior angles would be obtuse because they would be wider than 90 degrees.

Can someone pls help me answer this :/​
eimsori [14]

Answer:

y = - \frac{3}{2} x + 6

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + b ( m is the slope and b the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 6) and (x₂, y₂ ) = (4, 0) ← 2 points on the line

m = \frac{0-6}{4-0} = \frac{-6}{4} = - \frac{3}{2}

Since the line crosses the y- axis at (0, 6) ⇒ b = 6

y = - \frac{3}{2} x + 6 ← equation of line
