What is the system of equation for 2x+y=3 and x=2y-1

2x+y=3-    

Slope = -4.000/2.000 = -2.000

 x-intercept = 3/2 = 1.50000

 y-intercept = 3/1 = 3.00000

x=2y-1-

Slope = 1.000/2.000 = 0.500

 x-intercept = -1/1 = -1.00000

 y-intercept = 1/2 = 0.50000

Steps below

Step-by-step explanation:

Step  1  :

Equation of a Straight Line

Calculate the Y-Intercept

Calculate the X-Intercept

Calculate the Slope

Done!

Hope this helps.

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
