Step-by-step explanation:
....................
You need to follow the order of operations, so you would solve what is in the parentheses first. (I'm assuming that is the variable x in 2x and not a multiplication symbol. If it is, then just multiply 5 by 3 to get 15, and then multiply that by 2 to get 30) This will give you 15. Then you multiply 2x by 15 to get 30x.
Using the equation y = 3x – 5, what would the output be for an input of 4
Answer:
output(y)=7
Step-by-step explanation:
y=3(4)-5
<=> y= 12-5
<=> y= 7

Jan wants to buy maps for her trip. the maps cost $2.00 each and she has $25.00 write an equation to represent the amount she will have left of she buys maps
Answer:
f(m) = 25-2m
Step-by-step explanation:
Let m be the number of maps Jan buys.
Let f(m) be the amount she has left after buying maps
f(m) = 25-2m
Equation to represent the amount she will have left of she buys maps is
f(m) = 25-2m
What is an equation?"An equation is a mathematical statement that is made up of two expressions connected by an equal signs."
Given
Cost of each map = $2
Total amount Jan have = $25
Let m be the number of maps Jan buys.
Let f(m) be the amount she has left after buying maps
f(m) = 25-2m
Thus, equation to represent the amount she will have left of she buys maps is f(m) = 25-2m.

The Olympic swimmer, Michael Phelps, required 10,000 calories during training. He needed 30% protein, 50% carbohydrates and 20% fat. How many calories did he need for each nutrient?
1 gram of carbs= 4 calories, 1 gram of protein=4 calories, 1 gram of fat= 9 calories.
Answer:
750 grams of protein, 222.22 of fat, and 1,250 of carbs.
Step-by-step explanation:
3,000 calories from protein, 2,000 from fat, and 5,000 from carbs.
3000 / 4 = 750 grams of protein.
2,000 / 9 = 222.22 grams of fat.
5,000 / 4 = 1,250 grams of carbs.
11) Which of the following is zero of the polynomial x^3+x^2+x+1
1
-1
both options 1 and 2
None
please answer
Answer:
The correct answer is option 2: -1
Step-by-step explanation:
In order to check if a number is zero of a function or not, the numer is put into the function in plave of variable. If the answer is zero thent he number is zero of the function and if the answer is not zero the given number is not a zero of the function.
Given function is:
[tex]x^3+x^2+x+1[/tex]
Putting x=1
[tex]=(1)^3+(1)^2+1+1\\=1+1+1+1\\=4[/tex]
1 is not zero of the function.
Putting x = -1
[tex]=(-1)^3+(-1)^2+(-1)+1\\=-1+1-1+1\\=0[/tex]
-1 is zero of the given function.
Hence,
The correct answer is option 2: -1
f(x) = 8x^2 + 8x - 12 in vertex form
Answer:
f(x) = (x + 4)² - 4
Step-by-step explanation:
Write the equation f(x) = x² + 8x + 12 in vertex form by completing the square:
f(x) = (x² + 8x + (8/2)²) + 12 - (8/2)²
Simplify:
f(x) = (x² + 8x + 16) + 12 - 16
Subtract to find the 'k' value:
f(x) = (x + 4)² - 4. This is the equation in vertex form.
Answer:
y=8x2+8x−12
Step-by-step explanation:
Rewrite in vertex form and use this form to find the vertex (h,k).

a school has 294 chairs.there are 14 chairs at each table. two chairs will be removed from each table.how many chairs will be left in the cafeteria?
Answer:
252
Step-by-step explanation:
because there are 14 chairs at each table => there are: 294/14= 21 (tables)
two chairs will be removed from each table => the number of chairs removed are: 21.2 = 42 (chairs)
the chairs will be left in the cafeteria are: 294 - 42 = 252( chairs)
When two chairs will be removed from each table, then there would be 252 chairs left in the cafeteria.
The dividend divisor quotient remainder formula:Dividend = Divisor × Quotient + Remainder.
For given question,
total number of chairs = 294
there are 14 chairs at each table.
So, to find the number of tables in the cafeteria we need to divide total number chairs by 14.
The number of table would be,
= 294/14
= 21
This means, there are 21 tables.
If we remove two chairs from each table, then number of chairs at each table would be 14 - 2 = 12
So, the total number of chairs left in the cafeteria would be,
= 21 × 12
= 252
Hence, there will be 252 chairs left in the cafeteria.

if the measure of angle 1 is 57°, find the measures of angle 6
Answer:
123
Step-by-step explanation:
180 - 57 = 123
supplementary
Answer:
∠6 = 123°
Step-by-step explanation:
∠1 = ∠4 because they are vertically opposite angles and vertically opposite angles are equal.
∠4 + ∠6 = 180 (same side interior angles are equal)
∠6 = 180 - 57
∠6 = 123°
You are a building contractor. A customer asks you to build a ground-level deck that is 12 feet by 12 feet by 9 inches. You go to the lumberyard to order wood. The attendant assures you that the yard has enough wood to build the deck. According to the attendant, the yard currently has 1,750 cubic feet of lumber in its inventory.
Does the lumberyard have enough wood to purchase to build the deck?
1.There is not enough wood. The deck needs 86 board feet more wood than available.
2.There is enough wood. The yard has 130 board feet of wood more than you need.
3.There is enough wood. You need 1,296 board feet of wood to build the deck.
4.There is enough wood. You need approximately 1,556 board feet of wood to build the deck.
5.There is not enough wood. You need approximately 1,858 board feet of wood to build the deck.
Answer:
Number 3 will be the correct answer, and the yard will still have about 454 cubic feet of wood left

Answer:
2. B) n > 2
4. B) -3
5. C) 1[tex]\frac{1}{2}[/tex] (Which is equal to 1.5)
8. D) x > [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
2. -6n < -12
To solve for n, divide by -6. When divide by a negative, you flip the sign.
n > 2
4. 2(n + 5) [tex]\geq[/tex] 4 and 3(n - 1) < 3
Divide by 2 for the first inequality and divide by 3 for the second inequality.
n + 5 [tex]\geq[/tex] 2 and n - 1 < 1
Now subtract 5 and add 1
n [tex]\geq[/tex] -3 and n < 2
Since the inequality says and, both equations have to be true when n is plugged in. We can see that -3 works, since it is equal to -3 AND is less than 2.
5. 4x - 7 [tex]\geq[/tex] [tex]\frac{-12x+14}4}[/tex]
Multiply by 4 to both sides
16x - 28 [tex]\geq[/tex] -12x + 14
Now add 12x and add 28.
28x [tex]\geq[/tex] 42
Divide by 28 to get x.
x [tex]\geq[/tex] 1.5
So the answer is C.
8. 3(2x - 1) > 4x - 2
For this one, distribute the 3 to the numbers in the parentheses.
6x - 3 > 4x - 2
Add 3 and subtract 4x.
2x > 1
Divide by 2.
x > [tex]\frac{1}{2}[/tex]
Equation parallel y= -3 also passes through the point (2,5)
Answer:
When somethins is parallel it never crosses each other, this means the new equation has to have the same slope but, since y=-3 is a straight line we just have to make the new line also a straight line, maknig sure it passes through (2,5).
To do this make y equal the y-coordinate of the points it needs to pass through. This would make the answer y=5
