Answer:

a) $y= 2x+1$

The graph is on the figure with the red line

b) $2= 3*2 +b$

$b= 2-6 =-4$

And the equation would be:

$y = 3x -4$

The graph is on the figure with the blue line

Step-by-step explanation:

Part a

We know that a=2 and b =1

The general expression is given by:

$y= 2x+1$

The graph is on the figure with the red line

Part b

For this case we know that a=3 and we know a point given (2,2). Then we can find the value of b like this:

$2= 3*2 +b$

$b= 2-6 =-4$

And the equation would be:

$y = 3x -4$

The graph is on the figure with the blue line

Find the value of x y and z below !

ehidna [41]

Answer:

$x=67, y=121, z=65$

Step-by-step explanation:

One property of parallelogram is that opposite angles have the same measure, so we can write down:

$(y-9)=112\\y=121$

Another property is that two adjacent angles are supplementary (meaning that they add up to 180 degrees). Thus, the following equations are true:

$(z+3)+112=180\\(x+1)+112=180$

Solve the equations:

$(z+3)+112=180\\z+115=180\\z=65\\(x+1)+112=180\\x+113=180\\x=67$

To check, add up all 4 angles and check if they sum up to 360 degrees:

$x=67, y=121, z=65\\(y-9)+(x+1)+(z+3)+112=360\\(121-9)+(67+1)+(65+3)+112=360\\112+68+68+112=360\\360=360$

And please ignore the fact that I cannot insert the degree sign :(

Bess [88]

Answer:

6i - 5

Step by step:

Assuming x = i

Simplify step by step:

−3+3x−2+3x

=−3+3x+−2+3x

Combine Like Terms:

=−3+3x+−2+3x

=(3x+3x)+(−3+−2)

=6x+−5

Elodia [21]

Answer:

angle xyb will measure 123 degrees.

Step-by-step explanation:

because we know that angle ayz is 57 degrees and angle xyz is 90, we find that angle xya measures 33 degrees by subtracting 57 from 90. then, we can find angle xyb by subtracting 33 from 180, getting 147 degrees. when we add 147, 33, and 57, we get 237 degrees. finally, we subtract 237 from 360 and get 123 degrees, our final angle. hope this helps:)

Devin signs a note for a discounted loan agreeing to pay $2,700 in 6 months at a discount rate of 7%. Determine the amount of th

grandymaker [24]

Answer:

discount= $94.5

Proceeds=$2605.5

Step-by-step explanation:

amount Dawin has to pay= $2700

in 6 months time

at a discount rate of 7%

here future value = $2700

D= discount before m months is given by

$D= \frac{FV\times r\times m}{1200}$

m= 6 months, r= 7% and FV= 2700

putting values

$D= \frac{2700\times 7\times 6}{1200}$

solving we get

D= $94.5

now present value = future value - discount

=2700-94.5= $ 2605.5

here PV(present valve )= Proceeds= $2605.5
