Answer:
y=2x-3
Step-by-step explanation:
first, you have to get the y by itself (isolate the y). you do this by subtracting 4x from both sides.
4x-2y=6
-2y=-4x+6
next, you have to divide both side by -2 to isolate the y further and get this into slope-intercept form:
-2y=-4x+6
y=2x-3

7 x 5e = 105
plz help
e=3.
So this is how I approached this. Since 7 is being multiplied, I divided both sides by 7 so 105/7 = 15. Then it becomes simple as 5e=15. We divide both sides by 5 and get e=3. Tip: just try isolating the variable and then life is much easier.
Answer:
e = 3
Step-by-step explanation:
7 × 5e = 105
35e = 105
35e ÷ 35 = 105 ÷ 35
e = 3

A restaurant distributed 7,000 coupons. Over the next month, 3,290 of the coupons were redeemed. How many coupons were not used?
Answer:
3,710 coupons
Step-by-step explanation:
You have to do 7,000-3,290 to get the answer, as 7,000 is the total number of coupons given, and 3,290 is the amount of coupons that was used.
7,000-3,290=3,710
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

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

let f={(1,2),(2,3),(5,6),(7,8) evaluate f(2)and f(5)?
Given:
[tex]f=\{(1,2),(2,3),(5,6),(7,8)\}[/tex]
To find:
The values of f(2) and f(5).
Solution:
If an ordered pair [tex](x,y)[/tex] is in the function [tex]f[/tex], then [tex]f(x)=y[/tex].
In the given set of ordered pairs one ordered pair is (2,3). So, by using the above definition, we get
[tex]f(2)=3[/tex]
In the given set of ordered pairs one ordered pair is (5,6). So, by using the above definition, we get
[tex]f(5)=6[/tex]
Therefore, the value of f(2) is 3 and the value of f(5) is 6.
Use the table to find f(3).*

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.
