Answer:
Step-by-step explanation: A 4-column table with 4 rows. Column 1 is labeled Service with entries Restaurant, Florist, Cab Fare, Dog Groomer. Column 2 is labeled Cost with entries 40 dollars, 94 dollars, 32 dollars, 62 dollars. Column 3 is labeled Gratuity with entries 18 percent, 12 percent, 20 percent, 26 percent. Column 4 is labeled Tax with entries 8.5 percent, 12 percent, 0 percent, 5.75 percent.About how much should the gratuity for the restaurant server be? Round the percent of gratuity to the nearest benchmark percent to find the answer.$
Answer:
2x - 8
Parts of an equation:
2 - coefficient
x - variable
8 - constant
The number 2 is not a coefficient in the expression. FALSE.
The expression has three terms. FALSE. two terms only: 2x & 8
The variable in the expression is x. TRUE
The number 2 is a constant in the expression. FALSE
The expression has one variable term. FALSE. 2x is term but it's a combination of a number and a letter. Variable term is letter only.
Question:
Solve the equation 2x2−5x+3=0 by the method of completing square.
Answer:
We have,
2x2−5x+3=0
⇒x2−25x+23=0 (Dividing throughough by 2)
⇒x2−25x=−23 (Shifting the constant term on RHS)
⇒x2−2(45)x+(45)2=(45)2−23 (Adding (21Coeff.ofx)2 onboth sides)
⇒(x−45)2=1625−23⇒(x−45)2=16
Domain of 2(x + 5) is all real numbers.
The third angle is 60 degrees. A triangle has 180 degrees so 180-30-90=60
