Answer as a fraction: x = 5/2
Answer in decimal form: x = 2.5
=====================================================
Explanation:
Replace f(x) with 5
So we go from f(x) = 2x to 5 = 2x
Now isolate x. We do so by dividing both sides by 2 (this undoes the multiplication of 2 on x)
So we get
5 = 2x
5/2 = 2x/2 ... divide both sides by 2
5/2 = x
x = 5/2
x = 2.5

Answer:
you worked 14 hours
Step-by-step explanation:
W = 52 + 8h
164 = 52 + 8h
112 = 8h
14 = h
Answer:
The answer is 14 hours
Step-by-step explanation:
The question states that h means hours and w is the total amount of money received.
164 = 52 + 8h
-52 -52
112 = 8h
112/8 = 8h/8
14 = h
The answer is 14 hours (but you don't need to include the label when you submit your form). Plus we can see your email address which i suggest you shouldn't show next time :)

Find the inverse, g−1(x), of the following function: g(x) = 4x - 11
Answer:
[tex]g^{-1}[/tex] (x) = [tex]\frac{x+11}{4}[/tex]
Step-by-step explanation:
let y = g(x) and rearrange making x the subject, that is
y = 4x - 11 ( add 11 to both sides )
y + 11 = 4x ( divide both sides by 4 )
[tex]\frac{y+11}{4}[/tex] = x
Change y back into terms of x , with x = [tex]g^{-1}[/tex] (x) , thus
[tex]g^{-1}[/tex](x) = [tex]\frac{x+11}{4}[/tex]
Anthony has a part-time job. He decides to save $10 for every $50 that he spends. Final question: If Anthony saved $60, how much money did he earn?
Answer:
300$
Step-by-step explanation:
If he save 10 for every 50, you just divide. 60/10 = 6. He saved 6 times, if each time he saves he has 50 extra dollars, 6 * 50 = 300 because 6*5 = 30 and there is a extra 0 so 30 and 0 is 300

Match the percent expression to the equivalent dollar amount.
220% of $40
$90
125% of $80
$88
150% of $60
$75
300% of $25
$100
Answer:
90 = 150 of 60
88 = 220 of 40
75 = 300 of 25
100 = 125 of 80
Step-by-step explanation:
Answer:
90 = 150% of 60$
88 = 220% of 40$
75 = 300% of 25$
100 = 125% of 80$

graph the line with the equation y = -5/2x + 2
Answer:
Step-by-step explanation:
Answer:
If you want to get the result like I did, Desmos is a great website that help you graph any kind of equation.
Step-by-step explanation:
I placed y=-5/2x +2 into desmos and it spat out this graph. If you want to do it algabreacly, I suggest making an x and y t-chart and start plugging in x numbers in terms of y. Lets say you plug in 1 as x, you would to 5/2(1) +2 giving you 2 5/2 or 4 1/2 as your y coordinate if x is 1. This makes your point (1, 4 1/2). I'd say do about 3 coordinates at least and then draw a line straight through those point giving you your graphed equation.

Please solve this question.
Ram started his journey at 6:00 AM with an average speed at 20km/hr.
Hari started his journey two hours later (at 8:00 AM) with an average speed of 30km/hr.
We have to find time at which they meet each other[tex].[/tex]
★ Let they meet each other after t hours wrt 6:00 AM.
At that time, distance covered by ram must be equal to the distance covered by hari.
We know that,
distance = speed × time➤ Distance covered by Ram :
⭆ d₁ = v₁ × t
⭆ d₁ = 20 × t
➤ Distance covered by Hari :
Since hari started his journey after 2 hours so will take time = (t - 2) hours
⭆ d₂ = v₂ × (t - 2)
⭆ d₂ = 30 × (t - 2)
⭆ d₂ = 30t - 60
Now,
➠ d₁ = d₂
➠ 20t = 30t - 60
➠ 30t - 20t = 60
➠ 10t = 60
➠ t = 6 hrs
∴ They will meet at (6 + t) = 12PM
Hope It Helps!Answer: 12:00 pm (Noon)
Step-by-step explanation:
Let t represent the time (in hours) from 6:00 am
Use distance (d) = rate (r) × time (t)
Ram: time = t, r = 20 → d = 20t
Hari: time = t - 2, r = 30 → d = 30(t - 2)
Use Substitution method to solve the system of equations:
20t = 30(t - 2)
20t = 30t - 60
-10t = -60
t = 6
They travel the same distance when Ram rides his bike for 6 hours
and Hari rides his bike for 4 hours.
Ram: 6:00 am + 6 hours = 12:00 pm (Noon)
Hari: 8:00 am + 4 hours = 12:00 pm (Noon) [tex]\checkmark[/tex]
2x - 5y = 5 and y = x + 2
Answer:7
Step-by-step explanation:
Answer:
x = -5 & y = -3
Step-by-step explanation:
2x - 5y = 5 --------------------------(I)
y = x + 2 -----------------------(II)
Using substitution method
Substitute y = x + 2 in equation (I)
2x - 5(x + 2) = 5
2x - 5*x + (-5)*2 = 5
2x - 5x - 10 = 5
Combine like terms
-3x - 10 = 5 {Add 10 to both sides}
-3x = 5 +10
-3x = 15 {Divide both sides by (-3)}
x = 15/(-3)
x = -5
Substitute the x = (-5) in equation (II)
y = -5 + 2
y = -3
find the slope of(4,-6) and (-3,-12)
Answer:
[tex]m=\frac{6}{7}[/tex]
Step-by-step explanation:
Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Simply plug in your 2 coordinates into the slope formula to find slope m:
[tex]m=\frac{-12-(-6)}{-3-4}[/tex]
[tex]m=\frac{-12+6}{-7}[/tex]
[tex]m=\frac{-6}{-7}[/tex]
[tex]m=\frac{6}{7}[/tex]

Its been a while, forgot how to do this need some help.
Answer:
x=33
Step-by-step explanation:
The angles would need to add to 180 to be supplementary
4x+ x+15 = 180
Combine like terms
5x+15 = 180
Subtract 15 from each side
5x+15-15 =180-15
5x = 165
Divide by 5
5x/5 =165/5
x=33

What is true about the sign of the difference when a positive integer is subtracted from a negative integar
Answer:
negative
Step-by-step explanation:
Suppose we have positive integer x and negative integer -y.
Subtracting x from -y gives:
-y - x
Clearly, if -y is negative and we're subtracting even more (x) from it, the answer will still be negative.
So, the sign is negative.
