Answer:
√73 mi√134 ft.......................How many solutions can be found for the system of linear equations represented
on the graph?
A) no solution
3) one solution
D) infinitely many solutions
C) two solutions
Answer:
Infinitely Many Solutions
Step-by-step explanation:
They are the same line so they cross each other infinitely many times.
If you picked a point on the first equation it would be the same point on the second equation.
Answer:
D) Infinitely many solutions
Step-by-step explanation:
Given the follwowing systems of linear equations, y = x + 2, and -3x + 3y = 6:
Transforming -3x + 3y = 6 into its slope-intercept form, y = mx + b:
-3x + 3y = 6
Add 3x to both sides:
-3x + 3x + 3y = 3x + 6
3y = 3x + 6
Divide both sides by 3:
[tex]\frac{3y}{3} = \frac{3x + 6}{3}[/tex]
y = x + 2 ⇒ This is the slope-intercept form of -3x + 3y = 6. Since they are equivalent equations, then it means that their graphed lines coincide. Since any point on either lines coincide (or also exists) on the other line, then it means that the solutions to one of the equations will satisfy the other. Therefore, the given systems of linear equations have an infinitely many solutions.
Find the value of K so that line passing through the points (k,-1) and (-2,8) is parallel to the equation 3x+y=-7
Answer:
k =1
Step-by-step explanation:
3x + y = -7
y = -3x - 7
m = -3
Parallel lines have same slope
[tex]Slope = -3\\\\\dfrac{8-[-1]}{-2-k}=-3\\\\\\\dfrac{8+1}{-2-k}=-3\\\\\dfrac{9}{-2-k} = -3[/tex]
Cross multiply,
9 = -3(-2-k)
9 = 6 + 3k
9-6 = 3k
3 = 3k
3/3 = k
k = 1

what is the sum of two arithmetic means between 6 and 2
pls show solutions guys!!
Answer:
8Step-by-step explanation:
Let the numbers are:
6, x, y, 2Since the sequence is arithmetic, the difference of two consecutive terms is same:
d = x - 6 = y - x = 2 - yTherefore:
x = 6 + dy = 6 + 2d2 = 6 + 3dThe sum of the first two equations:
x + y = 6 + d + 6 + 2d = 6 + (6 + 3d)Substitute (6 + 3d) with 2 (the third equation) to get:
x + y = 6 + 2 = 8Which equation has the steepest graph
A) y = 8x - 1
B) y = -10x - 4
C) y = 7x + 3
D) y = -2x + 6

A model rocket is launched from the top of a building. The height (in meters) of the rocket above the grown is given by h(t)=-6t^2+30t+10 , where t is the time (in seconds) since the rocket was launched. What is the rocket’s maximum height?
Answer:
47.5 Meters
Step-by-step explanation:
Find where the derivative changes from positive to negative (local maximum)
h(t)=[tex]-6t^2+30t+10[/tex]
h'(t)=[tex]-12t+30[/tex]
Find where the derivative equals zero
Theres no spot where the derivative wont exist because its a polynomial.
-12t=-30
t=[tex]\frac{5}{2}[/tex]
Ill stop here because this is a parabola opening down and this is the only spot where there will be a horizontal tangent line so this is the x-coordinate of the vertex. AKA you don't need to test positive and negative on both sides.
Now plug into original equation
h(2.5)=[tex]-6(2.5)^2+30(2.5)+10[/tex]
=-37.5+75+10
=47.5

Answer:
y = 31
Step-by-step explanation:
We'll, if x + y = 10,
and x = -21,
then: -21 + y = 10.
To solve, add 21 on both sides to get y = 31
Hope this helps :)
Answer:Answer:
y = 31
Step-by-step explanation:
We'll, if x + y = 10,
and x = -21,

What is 6 1/2 + 9 3/8
Answer: 15 7/8
Step-by-step explanation:
Add the whole numbers first 6+9 to getting 15
Now find the lowest common denominator for both the fractions. In this case it is 8.
3/8 would stay the same however 1/2 would become 4/8. 4/8 + 3/8 is 7/8.
15 add 7/8 is 15 7/8
What number cannot be divided into 9 groups without a remainder?
Answer:
The answer is B) 432
Step-by-step explanation:
The 4 in 432 becomes a 3, because we can't subtract 6 from 3. The 3 becomes 13 and if we subtract 13 with 6... We get 7.
I got 0 with option B... With A I got 2 which is a remainder. With C I got 6.5 (repeating). And with D I got 7.77777777778.
Hence, B) 432 is the correct option.
Check screenshot of my work below.
(I forgot to include 48 on top of the division I just did. Don't mind that too much..)
A) 326
[tex] \frac{326}{9} [/tex]
[tex] = 36.2222222222 [/tex]
B) 432
[tex] \frac{432}{9} [/tex]
[tex] = 48[/tex]
C) 531
[tex] \frac{531}{9} [/tex]
[tex] = 59[/tex]
D) 630
[tex] \frac{630}{9} [/tex]
[tex] = 70[/tex]
so, the correct answer is option A.
£6000 is to be shared among David, Daniel and Dennis, Daniel is to get one and a half times as much as David, while Denis is to get three and a half times as much as David. Determine (i) the ratio in which the money is to be shared. (ii) the amount of money each will get.?
Answer:
(i) David: Daniel: Dennis= 2: 3: 7
(ii) David, Daniel and Dennis will get £1000, £1500 and £3500 respectively.
Step-by-step explanation:
(i) Let the amount of money obtained by David, Daniel and Dennis be x, y and z pounds respectively.
x +y +z= 6000 -----(1)
y= 1.5x -----(2)
z= 3.5x -----(3)
Let's write the amount of money each gets in terms of x.
David --- x
Daniel --- 1.5x
Dennis --- 3.5x
In ratio, David: Daniel: Dennis
= 1: 1.5: 3.5
= 2: 3: 7
This is obtained by multiplying 2 throughout the ratio as ratio is its simplest form is in whole numbers and does not have decimals.
_______
(ii) Now that we know how the money is shared in terms of ratio, we can easily determine how much each of them receives.
Total amount of money= £6000
Total number of units
= 2u +3u +7u
= 12u
Thus, 12 units represents £6000.
12u ----- £6000
1u ----- £6000 ÷12= £500
Amount of money David will receive
= 2u
= 2(£500)
= £1000
Amount of money Daniel will receive
= 3u
= 3(£500)
= £1500
Amount of money Dennis will receive
= 7u
= 7(£500)
= £3500
Extra notes:
• Units are represented by the letter 'u' in the working. They can also be called parts and their value is in relation to the total amount. Thus if David gets 2 units of the total money, and the total amount is 12 units, he receives 2/12 or ⅙ of the total sum of money.

Then write the linear factorization of the polynomial. Degree 3;
zeros: 2, 5 − i
The remaining zero of polynomial is (5 + i).
And, the linear factorization of the polynomial are;

What is Zeros of polynomial?
Zeroes of a polynomial are the points where the polynomial becomes zero.
Given that;
Zeroes of the polynomial are 2, 5 - i
Now, If one zero of polynomial is complex then another zero of the polynomial is its conjugate.
So, One root of polynomial = 5 - i
Then, The third zero of the polynomial = 5 + i
Thus, The polynomial are find as;
(x - 2) (x - (5-i)) (x - (5 + i)) = 0
So, The remaining zero of polynomial is (5 + i).
And, the linear factorization of the polynomial are;
(x - 2) (x - (5-i)) (x - (5 + i)).

Joe buys his son a Gatorade each time his son plays hockey. The Gatorade cost $2. His song usually plays 3 times a week for half a year. How much money can joe save if he brings water from home for his son instead of buying Gatorade?
Answer:$156
Step-by-step explanation: One year has 72 weeks in it. That means there's 26 weeks in half a year. If he gets a Gatorade three time each week that's 78 Gatorades.if each Gatorade costs two dollars then the dad would spend 156 dollars every half year.
The Pines Golf Course is offering free Ice cream cones to golfers who hit their tee shot on the green at hole 7! The following bar graph summarizes the tee shots from this morning.
Based on the data, what is a reasonable estimate of the probability that the next tee shot ends up on the green?
A: 14%
B: 17%
C: 18%
D: 21%
Explanation:
There are 4 shots that land on the green in this sample size. The height of the bar tells us this directly.
Add up the heights of each bar to get 4+5+7+3+5 = 24 which is the total number of shots. The probability of landing on the green is 4/24 = 1/6 = 0.1667 = 16.67% approximately. This rounds to 17%

(show work and I will not only mark brainliest, but I will rate 5 stars, follow you, and thank you on your profile.)
Step-by-step explanation:
Use the equation
[tex] \frac{x - x1}{y - y1} = m[/tex]
So plug in the numbers
[tex] \frac{ 2 + 2}{3 - 4} = \frac{4}{ - 1} = - 4[/tex]
So if y=mx+b and there is no intercept the equation would be
[tex]y = - 4x[/tex]
