if y=3x^3+x^2-5 and z=x^2-12 what polynomial is equivalent to 2(y+z)
Answer:
2y + 2z
6x³+2x²-10 + 2x²-24
6x³+4x²-34 ■
Step-by-step explanation:
The polynomial which is equivalent to 2 (y + z) is 6x³ + 4x² - 34.
What is Polynomial?A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer.
Here, y = 3x³+x²-5 and z = x²-12
Now,
2 ( y + z ) = 2 ( 3x³+x²-5 + x²-12 )
2 ( y + z ) = 2 ( 3x³ + 2x² - 17 )
2 ( y + z ) = 6x³ + 4x² - 34
Thus, the polynomial which is equivalent to 2 (y + z) is 6x³ + 4x² - 34.

A carpenter has at most $250 to spend on lumber. The inequality 8x+12y≤250 represents the numbers x of 2-by-8 boards and the numbers y of 4-by-4 boards the carpenter can buy. Can the carpenter buy twelve 2-by-8 boards and fourteen 4-by-4 boards?
Answer:
No, (12, 14) this is not a solution of the inequality
Step-by-step explanation:
(x, y)
x = 12 2-by-8 boards
y = 14 4-by-4 boards
(12, 14)
8x + 12y <= $250
This means that a 2-by-8 board cost $8 each, while a 4-by-4 board cost $12 each.
8(12) + 12(14) <= 250
96 + 168 <= 250
264 <= 250
264 is not less than or equal to 250

I got this right, look....
Evidence:
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
The ratios that have a unit rate greater than 1 are:
9/8 miles : 5/6 hours
4 miles : 3(1/3) hours
7 miles : 3/4 hours
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
9/8 miles : 5/6 hours
4 miles : 3(1/3) hours
7 miles : 3/4 hours
The unit rate of each given ratio.
9/8 miles = 5/6 hours
Multiply 6/5 on both sides.
6/5 x 9/8 miles = 1 hour
54/40 miles = 1 hour
27/20 miles = 1 hour
1.35 miles = 1 hour
4 miles = 3(1/3) hours
4 miles = 10/3 hours
Multiply 3/10 on both sides.
3/10 x 4 miles = 1 hour
6/5 miles = 1 hour
1.2 miles - 1 hour
7 miles = 3/4 hours
Multiply 4/3 on both sides.
4/3 x 7 miles = 1 hour
28/3 miles = 1 hour
9.33 miles = 1 hour
We see that,
All of them have unit rates greater than 1.
Thus,
The ratios that have a unit rate greater than 1 are:
9/8 miles : 5/6 hours
4 miles : 3(1/3) hours
7 miles : 3/4 hours

Find a positive coterminal angle less than 360°.
With the given angle -450
======================================================
Explanation:
The angle -450 is not between 0 and 360. Add on 360 so that we do one full revolution to get -450+360 = -90.
The angle -90 isn't between 0 and 360 either. We repeat the last step by adding on 360 to get -90+360 = 270.
The result 270 is between 0 and 360, so we stop here.
The angle -450 and 270 both point in the same direction. Both point directly south. This is why they are considered coterminal angles.

Answer: I would say B would be the answer Because....
Step-by-step explanation:
if about 20 to 23 cars pass through every 26 minutes, and haw many cars pass by in 156 minutes...
26 x 6 = 156
6 x 20 = 120
6 x 21 = 126
6 x 22 = 132
6x 23 = 138

In the school election James ran against Ben for secretary James received 75% of the votes if 240 students voted how many votes did James not receive?
Answer: James did not received 60 votes.
Step-by-step explanation:
Given: In a school election,
Percentage of votes received by James = 75%
Percentage of voted hadn't received by James = 100% - 75% = 25%
If 240 students voted , the number of votes hadn't received by James= 25% of 240
[tex]=\dfrac{25}{100}\times 240\\\\=\dfrac14\times240\\\\=60[/tex]

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 6, 4, 8/3... Find the 7th term.
Answer:
0.527
Step-by-step explanation:
The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 6, 4, 8/3... Find the 7th term
The sequence given in the above Question is a geometric sequence.
The formula for the nth term of a geometric sequence is given as:
an = a × r ^n - 1
Where
a = First term
r = Common ratio
n = nth term
From the above question, we are asked to find the 7th term
Hence:
a = 6
Common ratio = Second term/first term
= 4/6 = 2/3
n = 7
The 7th term = 6 × (2/3 )^7 - 1
= 6 × (2/3)^6
= 6 × (2/3)⁶
= 0.5267489712
Approximately to the nearest thousandths the 7th term = 0.527

In which quadrant does the point (15,-7) lie?
Answer:
Quadrant 4
Step-by-step explanation:
Quadrant 1: Positive x and Positive y
Quadrant 2: Negative x and Positive y
Quadrant 3: Negative x and Negative y
Quadrant 4: Positive x and Negative y
For point (15, -7), we have a Positive x and a Negative y so it belongs in Quadrant 4.
The quadrant the given point (15,-7) lie is fourth quadrant.
The first quadrant in Cartesian coordinate is given as;
= (x, y)
The second quadrant in Cartesian coordinate is given as;
= (-x, y)
The third quadrant in Cartesian coordinate is given as;
= (-x, -y)
The fourth quadrant in Cartesian coordinate is given as;
=(x, -y)
(15,-7) corresponds to (x, -y)
Thus, the quadrant the given point lie is fourth quadrant.

Write an equation in point-slope form of the line having the given slope that contains the given point. then graph the line
(dont think u can graph so its okay)
Answer:
y+2=.25(x+3)
Step-by-step explanation:
The point slope form is shown as follows
y-y₁=m(x-x₁)
We know that the slope (m) is equal to .25 and that x₁=-3 and y₁=-2
We can plug this in and get
y-(-2)=.25(x-(-3))
Simplify the signs to get
y+2=.25(x+3)
