1) 110+30+a = 180
a = 180-140 = 40
Obtuse angled triangle

2) 50+50+C = 180
C=180-100 =80
Acute angled triangle

3) 45+45+b =180
b =180-90 = 90
Right angled triangle

4) 45+60+C = 180
C = 180-105 =75
Acute angled triangle

5) 94+47+b =180
b = 180-141=39

Obtuse angled triangle

Consider the function. f(x)= -2/3x-24 Which conclusions can be drawn about f–1(x)? Select two options. f–1(x) has a slope of -2/

disa [49]

Answer:

(D) $f^{-1}{(x$) has an x-intercept of (-36, 0).$

(E) $f^{-1}{(x)$ has a range of all real numbers.

Step-by-step explanation:

Given the function: $f(x)= -\dfrac23x-24$

$f(x)+24= -\dfrac23x\\$Multiply both sides by $ -\dfrac32\\x=-\dfrac32(f(x)+24)\\f^{-1}(x)=-\dfrac32f(x)-36$

When y=f(x)=0

$f^{-1}(x)=-\dfrac32(0)-36\\f^{-1}(x)=-36$

Therefore, $f^{-1}(x)$ has a x-intercept of -36$

Also, $f^{-1}(x)$ has a range of all real numbers.

Therefore, Options D and E are correct.
