Answer:
x= -1 y=3
Step-by-step explanation:
Answer:
x = -1
y = 3
Step-by-step explanation:
2x +y =1 3x -y= -6
Add the two equations together to eliminate y
2x +y =1
3x -y= -6
------------------
5x = -5
Divide by 5
5x/5 = -5/5
x = -1
2x+y = 1
2(-1) +y = 1
-2 +y =1
Add 2 to each side
y = 1+2
y =3

Answer:
The number is 2
Step-by-step explanation:
Twice a number (z) = 2*z = 2z
Twice a number (z) added to 21 = 2z + 21
9 times the number added to 7 = 9z + 7
9z + 7 = 2z + 21
Subtract 2z form both sides
9z - 2z + 7 = 21
7z + 7 = 21
Subtract 7 from both sides
7z = 21 - 7
7z = 14
Divide both sides by 7
z = 14/7
z = 2
Find the circumference of a circle with diameter,
d
= 7.18m.
Give your answer rounded to 2 DP.
Answer:
C = 22.56
Step-by-step explanation:
The equation for the circumference of a circle is [tex]C=2\pi r[/tex].
The radius is half the diameter so [tex]r=\frac{7.18}{2}=3.59[/tex]
Plug the radius into the equation.
[tex]C=2*\pi *3.59[/tex]
[tex]C=22.55664[/tex]
Given:
Diameter of circle = 7.18 m
To find:
Circumference of the circle
Steps:
We know that radius is equal to half of the diameter
r = d/2
r = 7.18/2
r = 3.59 m
Now circumference is equal 2πr
Circumference = 2πr
Circumference = 2 × 3.14 × 3.59 (taking pi as 3.14)
Circumference = 6.28 × 3.59
Circumference = 22.5452
Circumference ≈ 22.55 meters
Therefore, the circumference of the circle is approximately 22.55 meters

dont answer if you dont have the answer I will report you The graph of a function contains the points (–1, –4), (0, 1), (1, 4). Is the function linear? Explain.
1. The function is linear because the points are not in a straight line.
2. The function is linear because the graph containing the points is not a straight line.
3. The function is linear because the points are in a straight line.
4. The function is not linear because the graph containing the points is not a straight line.
Answer:
The function is linear because the points are not in a straight line.Points that lie along the same line are said to be "collinear" and collinear points must have the same slope between any pair of points.
~ƒöᏝϗʆѻʁᶥąռ¹₃
[tex]\huge\boxed{\underline{\bf \: Answer}}[/tex]
The answer will be option 1 :-
The function is linear because the points are not in a straight line.Well, for a straight line the points formed are known as collinear points & the points given ->( -1, –4), (0, 1), (1, 4) are not collinear as they are not formed in the same line of the graph. Also, graphs have straight lines. From this we can see that none of the other options work. Hence, option 1 is the correct answer (✓).

Tyler has $600 to spend at a bicycle store for some new gear and biking outfits. Assume all prices listed include tax. He buys a new bicycle for $233.09. He buys 3 bicycle reflectors for $16.38 each and a pair of bike gloves for $29.13. He plans to spend some or all of the money he has left to buy new biking outfits for $52.48 each. Write and solve an inequality which can be used to determine xx, the number of outfits Tyler can purchase while staying within his budget.
Answer:
x ≤ 5.5
Step-by-step explanation:
Amount with Tyler = $600
Cost of new bicycle = $233.09
Cost of 3 bicycle reflectors = $16.38 * 3
= $49.14
Cost of bike gloves = $29.13
Cost of biking outfit = $52.48
Number of biking outfit = x
233.09 + 49.14 + 29.13 + 52.48x ≤ 600
311.36 + 52.48x ≤ 600
52.48x ≤ 600 - 311.36
52.48x ≤ 288.64
x ≤ 288.64/52.48
x ≤ 5.5
Number of biking outfit = x
x ≤ 5.5

John works a fortnightly wage of $750.00. If his basic week is 40 hours. what is his: Weekly wage basic rate and basic fortnight??
Answer:
Basic wage rate = $9.375 per hour
Step-by-step explanation:
Given :
Fortnight wage = $750
Basic week, hours worked per week = 40 hours
Weekly basic wage rate :
Fortnight = 2 weeks
Hence, weekly wage = fortnight wage / 2 = 750 /2 = $375
Weekly basic wage rate = $375 / Number of hours worked per week = $375 / 40 = $9.375 per hour

Question 17 The numbers in the circles go together in a certain way. Find the missing number marked by the question mark: 180, 14 120, 8 A:70 B: 80 C:60 D: Mr Sockman ?, 4 D:40
Answer:
B. 80
Step-by-step explanation:
According To Question, We Have
(180,14) (120,8) (? , 4) (220,18)
it Clearly Visible That ( 180*a+b=14 ) only Possible when we Put a=1/10 & b=-4. Thus, (180*1/10)-4 ⇔ 18-4 = 14Same For All (120*a+b=8)Thus, (120*1/10)-4 ⇔ 120-4 = 8
Now (?*1/10)-4=4 solve it .
Thus, ?*1/10=8⇔?=80 is Our Missing Number .
Joe works mowing lawns and babysitting. He earns $9.10 an hour for mowing and $7.90 an hour for babysitting. How much will he earn for 1 hour of mowing and 5 hours of babysitting?
Answer:
Joe would receive $9.10 for One hour of mowing the lawn and $39.50 for Five hours of babysitting, which (if needed) adds up to $48.60
Step-by-step explanation:
It's as simple as multiplication. Since he only mowed the lawn for one hour, it would only be $9.10. Since he babysat for 5 hours, you'd simply multiply $7.90 by five, giving you the answer $39.50

which is the missing number in the sequence below?
5,6,9,15,?,40
Answer:
25
Step-by-step explanation:
The pattern is + 1, + 3, + 6,... i.e. + 1, + (1 + 2), + (1 + 2 + 3),...
.'. Missing number = 15 + (1 + 2 + 3 + 4) = 25.
Answer: 25!
Step-by-step explanation:
5, 6, 9, 15, ?, 40
5 + 1 = 6
6 + 1 + 2 = 6 + 3 = 9
9 + 1 + 2 + 3 = 9 + 6 = 15
15 + 1 + 2 + 3 + 4 = 15 + 10 = 25
25 + 1 + 2 + 3 + 4 + 5 = 25 + 15 = 40

Find the distance that the points is given on the graph ?
From the graph, the given points are (2,-1) and (4,0). Use the distance between two points formula:
[tex] \large \boxed{ \sqrt{ {(x_2 - x_1)}^{2} + {(y_2 - y_1)}^{2} } }[/tex]
Substitute these points in the formula.
[tex] \large{ \sqrt{ {(2 - 4)}^{2} + {( - 1 - 0)}^{2} } } \\ \large{ \sqrt{ {( - 2)}^{2} + {( - 1)}^{2} } } \\ \large{ \sqrt{4 + 1} \longrightarrow \sqrt{5} }[/tex]
Hence, the distance is √5
Answer

Which of the following is the explicit rule for a geometric sequence defined by
a recursive formula of…
A. an = 13.7041
OB. a, = 13.70-1
O C. a, = 7.13+1
O D. an = 7.130-1
Answer:
D
Step-by-step explanation:
Always apply the formula a_n=ar^(n-1) in this type of questions, since you know that the first term, a is 7 and the common ratio, r is 13. Therefore you can substitute a = 7 and r = 13 into the equation which equals to a_n=7×13^(n-1)
The explicit rule for a geometric sequence defined by,
a(n) = 7 × 13ⁿ⁻¹
We have to given that,
a (n) = 13 a (n - 1)
Now, We can simplify as,
a (n) / a (n - 1) = 13
a (n) = 13 a (n - 1)
Since, We know that,
a(n) = a × rⁿ⁻¹
Here, a = 7
a(n) = 7 × 13ⁿ⁻¹
Hence, Option c is true.
