The coeficient of y² in the expression is the number 3
What is an algebraic expression?An algebraic expression is a set of numbers and letters that make up an expression that has a meaning, the letters are variables and the numbers are coefficients or independent terms, algebraic expressions can be part of an equation and model mathematical processes.
In the given expression we have the following:
3y² + 4x
As we are asked for the coefficient of the variable "y" then we must take the number that is just before the letter which in this case is the number 3.
3 is the coefficient of y²

Heather has a thin piece of wood that measures 14 inches long by 13 inches wide. She wants to make a box with a height of 3 inches. Heather says that she has enough wood to make a box that has bases measuring 6.5 inches by 6.5 inches. Do you agree?
Answer:
Yes, I agree. Since the area of the piece of wood is greater than the area of the box she wants to make, then she has enough wood to make the box.
Step-by-step explanation:
First, we will calculate the area of the piece of wood Heather has
Area (A) = Length (l) × Width (w)
From the question, l = 14 inches and w = 13 inches
A = 14 inches × 13 inches
A = 182 squares inches
Hence, the area of the piece of wood is 182 square inches
Now, we will calculate the total surface area of the box she desires to make
Area (A) of a box is given by
A = 2lw + 2lh + 2wh
Where l is the length
w is the width and
h is the height
She wants to make a box with a height of 3 inches and bases measuring 6.5 inches by 6.5 inches.
i.e h = 3 inches, l = 6.5 inches and w = 6.5 inches
∴ A = 2(6.5×6.5) + 2(6.5×3) + 2(6.5×3)
A = 84.5 + 39 + 39
A = 162.5 square inches
Hence, the area of the box she wants to make is 162.5 square inches
Since the area of the piece of wood is greater than the area of the box she wants to make, then she has enough wood to make the box.

Choose the equation below whose axis of symmetry is x = 2. (1 point)
O y=x²-2
O y = x2 - 4x + 2
O y = x2 + 4x + 2
O y=x²-4
Answer:
y = x2 - 4x + 2 ; y=x²-4
Step-by-step explanation:
Axis of symmetry = - b /2a
y=x²-2
a = 1 ; b = - 2
x = - (-2) / 2(1)
x = 2/2 = 1
y = x2 - 4x + 2
a = 1 ; b = - 4
x = - (-4) / 2(1)
x = 4/2 = 2
y = x2 + 4x + 2
a = 1 ; b = 4
x = - 4 / 2(1)
x = - 4/2 = - 2
y=x²-4
a = 1 ; b = - 4
x = - (-4) / 2(1)
x = 4/2 = 2
Answer:
y = x2 - 4x + 2 ; y=x²-4

(6,-2)
(2,-6)
(-6,2)
(-2,6)
Answer:
(-6,2) third option is correct
Step-by-step explanation:
x+5y=4 equation1
x-5y=-16 equation 2
by adding both equations we got
2x=-12
x=-6
now put x=-6 in any of the equation to get y...
-6+5y=4 equation 1
5y=4+6
5y=10
y=10/5
y=2
(-6,2)
Answer:
(-6, 2)
Step-by-step explanation:
Put (-6, 2) into eq1 and eq2
1. (-6) +5(2)= -6 +10 =4
2.(-6) - 5(2)= -6-10 = -16
only one that works is (-6, 2)

Answer:
(x, y) = (7, 2 2/3)
Step-by-step explanation:
We can multiply the first equation by 2/5 to get ...
8x -6y = 40
The second equation gives an expression for 6y that we can substitute.
8x -(3x -5) = 40
5x +5 = 40 . . . . . eliminate parentheses
x +1 = 8 . . . . . . . .divide by 5
x = 7 . . . . . . . . . .subtract 1
Using the second equation, we find ...
3(7) -5 = 6y
y = 16/6 = 2 2/3
The coordinates of the point of intersection are (x, y) = (7, 2 2/3).

Tim washed 15 cars in 3hours.how many cars can he wash In 7 hours?
Answer:
35 cars
Step-by-step explanation: ok so here is how you do it you divide 15 and 3 to find out how much cars Tim washed in one hour so in this case we got 5 then we multiply the hours by 7 and we get 35 cars
Answer:
I believe the answer is 35.
Step-by-step explanation:
15+15=30
30+5=45
1 hour = 5 cars
3 hours = 15 cars
6 hours = 30 cars
7 hours = 35 cars
15 divided by 3 = 1

Step-by-step explanation:
Osvoldo has a goal of getting at least 30, percent of his grams of carbohydrates each day from whole grains. Today, he ate 220 grams of carbohydrates, and 55 grams were from whole grains.
Answer:
No
He ate only 25% from whole grains
He ate 5% less grams from his goal
Step-by-step explanation:
Osvoldo has a goal of getting at least 30, percent of his grams of carbohydrates each day from whole grains. Today, he ate 220 grams of carbohydrates, and 55 grams were from whole grains.
Did Osvoldo meet his goal? Why? , Osvoldo ate grams of whole grains than his goal.
Percent of whole grains ate = grams of whole grain / total carbohydrates) x 100
(55/220) x 100 = 25%
This is less than his goal of 30% by (30% - 25%) 5%
Answer:
No, Osvoldo 11 grams of whole grains less than his goal.
Step-by-step explanation:
30% x 220
30% = 30/100 = 30 ÷ 100
30 ÷ 100 = 0.3
0.3 x 220 = 66
66 - 51 = 11
