Is the open sentence 3z = 2z +5 true or false when z=5?

If 3z=2z+5 and z=5, then you’d just plug the 5 in.

3(5)=2(5)+5 —> 15=10+5 —> 15=15

This statement is TRUE because 15 does equal 15.

I hope this helps. :)

Help me and i will help i back pls is due tomorrow pls help me
marusya05 [52]

Answer:

Step-by-step explanation:

E) y +17 =2

y =2-17 = -15

A) 19=a+5

a=19-5= 14

Y) n-6= -50

n=-50+6= -44

L) let the number be p

p+9= -30

p = -30-9= -39

L) -9 + m =20

m = 20+9 = 29

E) 7 = x -23

x = 7+23 = 30

W) 8 +q = -11

q = -11-8 = -19

T) k -8 = -3

k = -3+8 = 5

T) 3 = 10+v

v = 3-10 = -7

H) t-(-1) =45

t+1 =45

t = 45-1 = 44

N) let the number be b

b-20 = -75

b = -75+ 20 = -55

Q) x + (-3) = 22

x = 22+3 = 25

E) p-(-3) =100

p+3=100

p = 100-3 =97

T) 25 + d =8

d = 8-25 = -17

C) -16 + b = 32

b = 32+16 = 48

L) w+38=5

w = 5-38 = -33

O) j+(-61)= -2

j = -2+61 = 59

H) -9 = h+47

h = -9-47 = -56

E) 13=x-13

x = 13+13 = 26

O) t-(-29) = 29

t+29 = 29

t = 29-29 = 0

What’s the answer to this problem?
harkovskaia [24]

Answer:

6 = f(4) \\  \\ 0 = f(-2)

Step-by-step explanation:

Think of <em>f</em>(<em>x</em>). Those numbers in parentheses next to the <em>f</em><em> </em>are x-coordinates, all you have to do is look in the chart and see what y-coordinate they gave you with respect to the given x-coordinates.

I am joyous to assist you anytime.
