I have a few questions!<br> a) x−1.27=4.09<br> b) 2.3−y=2.301<br> c) t+3.04=14.3<br> d) 1.1+k=5.67
maks197457 [2]

Answer:

a.)  x = 5.36

b.)  y = - 0.001

c.)  t =  11.26

d.)  k =  4.57

Step-by-step explanation:

a) x−1.27=4.09

b) 2.3−y=2.301

c) t+3.04=14.3

d) 1.1+k=5.67

Solving. right?

a.)  x = 4.09 + 1.27 = 5.36

b.)  y = 2.3 - 2.301 = - 0.001

c.)  t = 14.3 - 3.04 =  11.26

d.)  k = 5.67 - 1.1  =  4.57

(2,-1) <br> y-intercept -3 <br> slope 1/2<br><br> Write an equation with the given info above.
jek_recluse [69]

y-intercept -3  

slope 1/2

is sufficient info with which to write an equation for a straight line:

y = mx + b becomes y = (1/2)x - 3.

You should check this by determining whether or not (2,-1) satisfies this equation.
