Answer:
y= 2x +8
Step-by-step explanation:
y= 2x+3
gradient of given line = 2
(coefficient of x term when the coefficient of y is 1)
Parallel lines have the same gradient.
Hence gradient of the unknown line is 2.
y= 2x +c
To find the value of c, substitute a coordinate.
When x= 7, y=6,
6= 2(7) +c
6= 14 +c
c= 6-14
c= -8
Thus, the equation of the line is y= 2x +8.
-If f(x) = 4x - 6 and g(x) = 2x, find Ax) g(x).

Hope it helps..
Good luck on your assignment
The coordinates of the midpoint of the segment whose endpoints are A(2, 6) and B(6, 8) will be (4, 7).
What is the midpoint of line segment AB?Let C be the mid-point of the line segment AB.
A = (x₁, y₁)
B = (x₂, y₂)
C = (x, y)
Then the midpoint will be
x = (x₁ + x₂) / 2
y = (y₁ + y₂) / 2
AB has endpoints at A(2, 6) and B(6, 8). Then we have
(x₁, y₁) = (2, 6)
(x₂, y₂) = (6, 8)
Then the mid-point will be
x = (2 + 6) / 2
x = 8 / 2
x = 4
y = (6 + 8) / 2
y = 14/2
y = 7
Then the coordinates of the midpoint of the segment whose endpoints are A(2, 6) and B(6, 8) will be (4, 7).

[tex] \sqrt[3]{4} \times \sqrt{3} [/tex]
we can rewrite the radicals and then replace them into the multiplication, as follows:
[tex] \sqrt[3]{4} = 4^{\frac{1}{3}} = 4^{\frac{1}{3} \times \frac{2}{2}} = 4^{\frac{2}{6} = \sqrt[6]{16}[/tex]
[tex] \sqrt{3} = 3^{\frac{1}{2}} = 3^{\frac{1}{2} \times \frac{3}{3}}} = 3^{\frac{3}{6}} = \sqrt[6]{27} [/tex]

10 pens left for himself.
Answer:
Im assuming they want to know how many were given to each friend? each friend would get 5 gel pens
Step-by-step explanation:
subtract the 10 that ram kept for himself from the original 35,you get 25,then divide 25 by 5 (because there is 5 friends ) which is 5 gel pens per friend
Suppose you will perform a test to determine whether there is sufficient evidence to support a
claim of a linear correlation between two variables. Find the critical values of r given the
number of pairs of data n and the significance level a.
n=12. a.= 0.01
Answer:
The critical values of r are -0.708 and 0.708.
Step-by-step explanation:
A statistical test is being performed to determine whether there is any linear correlation between two variables.
The hypothesis can be defined as follows:
H₀: There is no linear correlation between two variables, i.e. ρ = 0.
Hₐ: There is a significant linear correlation between two variables, i.e. ρ ≠ 0.
The test statistic is given as follows:
[tex]t = \frac{r\sqrt{n-2}}{\sqrt{1-r^{2}}}[/tex]
The degrees of freedom of the test is:
[tex]\text{df}=n-2=12-2=10[/tex]
The significance level of the test is, α = 0.01.
The critical values of r are:
[tex]r_{\alpha/2, (n-2)}=r_{0.01/2, (12-2)}=r_{0.005, 10}=\pm0.708[/tex]
*Use the r critical value table.
Thus, the critical values of r are -0.708 and 0.708.
From the 'r' table, the values of 'r' are -0.708 and 0.708.and this can be determined by using the hypothesis test.
Given :
Suppose you will perform a test to determine whether there is sufficient evidence to support the claim of a linear correlation between two variables.Number of pairs of data n and the significance level a is n = 12, a = 0.01.The hypothesis test is performed in this problem. The null and alternate hypothesis is:
[tex]\rm H_0 : p=0\\[/tex]
[tex]\rm H_1:p\neq 0[/tex]
The t-statistics is given by:
[tex]\rm t =\dfrac{r\sqrt{n-2} }{\sqrt{1-r^2} }[/tex]
Degree of freedom is given by:
df = n - 2 = 12 - 2 = 10
The significance level for this test is [tex]\alpha = 0.01[/tex]
Now, the critical value r is given by:
[tex]\rm r_{\alpha /2,(n-2)}=r_{0.01/2,(12-2)}=r_{0.005,10} = \pm0.708[/tex]
So, from the 'r' table, the values of 'r' are -0.708 and 0.708.

Answer:
t = 1
Step-by-step explanation:
16 - 2t = 5t + 9
1) First move 5t to the left side
16 - 2t - 5t = 9
2) Then move 16 over to the right side
-2t -5t = 9 - 16
3) simplify both sides
-7t = -7
4) divide both sides by 7
-t = -1
5) divide both sides by -1

Answer:
1. 50
2. 12
Step-by-step explanation:
Answer:
2. 50 stamps
3. 12 minutes
Step-by-step explanation:
2. Darius had 15 stamps, then he ordered 3 rolls. You can determine how many he got from the rolls by subtracting the total from 15. 165 - 15 = 150.
Now we know that there were 150 stamps in the rolls Darius ordered. Divide 150 by 3 (3 rolls) to find the number of stamps in each roll!
150/3 = 50.
3. First, remember that 1 hour = 60 minutes.
We want to find how long America played soccer on Monday, which is the same amount of time she played on Tuesday and Wednesday as well. This means we can subtract Thursday and Friday's time from 60 minutes, then divide that time by 3, to find the time she played on Monday.
60 - 14 - 10
= 36 minutes
Now, we divide 36 minutes by 3 to get 12 minutes.

21.05 divided by 0.2
Answer:
[tex]\frac{21.05}{0.2}=105.25[/tex]
Step-by-step explanation:
you have to do long division, but there is a number of steps, too many to put in here, but just check on calculator if you want to make sure
21.05 divided by 0.2 equals to 105.25
What is division?Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers.
The process of dividing a number up into equal parts, and finding how many equal parts can be made.
Division is a process of splitting a specific amount into equal parts. For example, we can divide a group of 20 members into 4 groups of 5 members.
Given that, 21.05 divided by 0.2
So, 21.05 ÷ 0.2 = 21.05/0.2
Multiply by 100
= 21.05 x 100 / 0.2 x 100
= 2105/20
= 421/4
= 105.25
Hence, 21.05 divided by 0.2 equals to 105.25

it is the second option. answer is x[tex]\leq[/tex]-8/3 or x>4
Step-by-step explanation:
we have the inequality 3x+8/x-4=0
we first multiply both sides by 4 the 4 cancels out on the left-hand side and 4*0 is 0 so we now have 3x+8=0 then we subtract both sides by 8 and get 3x=-8 then we divide both sides by 3 and get x=-8/3

Order the cones from least volume to greatest volume
Cone A r=5 inches h=6 inches
Cone B r= 7 inches h=4 inches
Cone C r=6 inches h=5 inches
Answer:
Cone A, Cone C, Cone B
Step-by-step explanation:
The volume of a cone is V=πr^2h/3 where V represents the volume, r represents the radius, and h represents the height.
That means the volume of cone A would be:
V = π * 5^2 * 6/3
V = π * 25 * 2
V = 50π
And the volume of Cone B would be:
V = π * 7^2 * 4/3
V = π * 49 * 4/3
V = 65.33π (about)
Lastly, the volume of Cone C would be:
V = π * 6^2 * 5/3
V = π * 36 * 5/3
V = 60π
65.33π > 60π > 50π
Therefore, Cone B has the largest volume, then Cone C, and, lastly, Cone A.

Bryce did chores every single day in september.It took Bryce 7/8 hours to completing his chores on 20 of the days.The remaining days of the month it took him 1 hours to complete his chores.How many hours did Bryce do chores in September?(there are 30 days in September). ANSWER STEP BY STEP. PLZZZ ANSWER I REALLY NEED HELP
Answer:
Step-by-step explanation:
Because Bryce did 7/8 hours every day for 20 days,
7/8 hours is 52.5 minutes.
so then times 20, you will get 1050 minutes.
Then divided by 60(minutes per hour) you will get 17.5 hours,
which means she did 17 hours and 30 minutes in the first 20 days,
then you plus the last 1 hour per day for 10 days,
you will get 10 hours plus 17 hours and 30 minutes.
So Bryce have worked 27 and 30 minutes in september.

Arthur is organising his collection of DVDs. He has 112 altogether.
The ratio of comedy films to
action to horror is 6 : 7 : 3
How many of each type of DVD does he have?
Comedy
Action
Horror
Answer:
42 Comedy, 49 Action, 21 Horror
Step-by-step explanation:
6 comedy : 7 action : 3 horror = 16 parts or if you think of it as a fraction, 16 is the denominator and the numbers for each ratios are the numerators
112 (the total)/16 = 7 movies per part
6 parts of comedy = 6 x 7 = 42
7 parts action = 7 x 7 =49
3 parts horror = 3 x 7 = 21
Another way to think of it is:
(ex. comedy)
6/16=x/112
(CROSS MULTIPLY HERE)
16x=672
x=42
