Asap need to be answer !

a) find the value of 2x + y when x = 4 and y = 3
b) find the value of a2 + b when a =-2 and b = 5

a. 11

b.1

Step-by-step explanation:

a. 2(4)+3= 8+3=11

b. (-2)2+5= -4+5=1

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
