A. Translate each of the following into algebraic expressions: (1 point each)
1.x plus y squared ---> x + y^2
2.8 times a number, x, decreased by y ---> 8x - y
3.the sum of x and y, squared ---> (x + y)^2
4.3 times the difference of x and y ---> 3( x - y)
5.6 less than x cubed --- > x^3 - 6
B. Translate the following phrases into algebraic expressions. Explain,
in complete sentences, the difference between the two. (3 points)
´twice the sum of x and y ---> 2(x + y)
´the sum of twice x and y ---> 2x + y
The first one adds first x and y, and then doubles the result, while the second one first doubles de value of x and the adds y.
C. Create your own example of a mathematical phrase you might hear in
the real world and provide the translation for it. Be sure to identify
what part of the phrase i
The sales of this year exceeded the sales of last year in tweny millions.
y = x + 20,000,000, where x represents the sales of last year and y represents the sales of this year,
Answer:
x = 6
Step-by-step explanation:
Since the triangle is equilateral then sides are congruent.
Equate any 2 sides and solve for x
13x + 5 = 8x + 35 ( subtract 8x from both sides )
5x + 5 = 35 ( subtract 5 from both sides )
5x = 30 ( divide both sides by 5 )
x = 6
JK = (13 × 6) + 5 = 78 + 5 = 83
KL = (17 × 6) - 19 = 102 - 19 = 83
JL = (8 × 6) + 35 = 48 + 35 = 83
ΔJKL is equilateral with side = 83
Answer:
3.066543
Step-by-step explanation:
This number is between 3.077243 and 3.0721
Answer:
If A = 8, B = 5
If A = 20, B = 3
Step-by-step explanation:
4x²(2x³ + 5x)
8x⁵ + 20x³
If A = 8, B = 5
If A = 20, B = 3
Just divide 40.25 by 3.5. You get 11.5. So his pay rate is 11.5 every hour.
I hope this helps :)
