Write the equation of the line that is perpendicular to y=3x-6 and passes through the point
x, y
(2,0)
Perpendicular is the negative reciprocal so the slope is -1/3
Need to know b and the full equation
With work please. Thank you!
Answer:
y=-1/3x+2/3 (please mark brainliest)
Step-by-step explanation:
start with y=3x+6
you can get the slope of the perpendicular line by dividing the slope by -1,
so the slope of the new line is -1/3.
using the point and the slope of the new line, we can put it into point-slope form:
y-y₁=m(x-x₁)
y-0=-1/3(x-2)
simplify:
y=-1/3x+2/3
this is the final equation in the form y=mx+b
evaluate 3d/2a, when d=4 and a = -1

A shop has a sale that offers 20% off all prices.On the final day reduce all the sale prices by 25%.Linz buys a radio on the final day.Work out the overall percentage reduction on the price of the radio
Answer:
40%
Step-by-step explanation:
Original price = x
Sale = 20% off
20% / 100 = 0.2 to convert from a percent to a decimal
Sale = x - 20% of x = x - 0.2x = 0.8x
Sale price = y = 0.8x
Reduction of sale prices = 25% = 0.25
Reduction = y - 25% of y = y - 0.25y = 0.75y
End price in terms of original price (x):
0.75y = 0.75(0.8)x
= 0.6x
End price = 0.6 or 60% of original price, coming out to a 100-60 = 40% overall percentage reduction

You can solve any equation in the form a(x + b) = c without writing out both steps of the two-step solution process.
a. Isolate the variable x, so that it has a coefficient of 1.
b. Use your answer to solve 4(x - 7) = 20.
Answer:
ax+ab-c=0, 12
Step-by-step explanation:
If x=1, then 4(x-7)=20
4x-28=20
add 28 on both sides
48/4=x
x=12
Answer:
this is my answer
Step-by-step explanation:
4(x-7)=20. divide both sides
x-7=5 move the constant to the right
x=5+7. calculate
so the answer is x=12

Darla ran 1/2 mile. Laura ran 5/8 mile. How many miles did they run altogether?
Answer:
1 1/8 mile
Step-by-step explanation:
when it says altogether most of the time you're supposed to add.
When you add fractions you need to have both denominator (number below the line) be the same. and sense 1/2 and 4/8 are equal we will replace it.
you add the numerators (top numbers) and keep the denominator (bottom number)
[tex]\frac{4}{8} + \frac{5}{8} = \frac{9}{8} =1\frac{1}{8}[/tex]
Sense the numerator is bigger you subtract the bottom number from the top number and put a 1 in front of the fraction.
what is _ percent of 100 is 14
Answer:
It should be 14 percent.
Step-by-step explanation:
14 percent is just 14/100, which if you multiply by 100 gives you 14.
14%
Step-by-step explanation:
Whenever you have anything over 100 (e.g 40/100) that number is always gonna be 40. Like multiplying by 1. 9*1 is 1. Assume the 9 is 90 and assume the 1 is 100. It's always gonna be the numerator instead of the denominator.

what is 2x+3=4 [tex]mbjbjjnjnjknjn[/tex]
Answer:
x = [tex]\frac{1}{2}[/tex]
Step-by-step explanation:
2x + 3 = 4
subtract 3 from both sides to get x by itself on the left side:
2x = 1
divide both sides by 2:
x = [tex]\frac{1}{2}[/tex]

A bacterial population has an exponential growth rate of 11.2% per hour. If there were 480 bacteria initially, what would the bacterial population be after 5 hours
The number of bacterial population after 5 hours is; 816
The formula for the exponential growth of the population is;N(t) = N_o(1 + r)^(t)
Where;
N(t) is number of bacteria after t hours
N_o is number of bacteria initially
r is growth rate
t is time
We are given;N_o = 480
r = 11.2% = 0.112
t = 5
Thus;N(5) = 480(1 + 0.112)^(5)
N(5) = 816.14
Approximating to a whole number gives; N(5) = 816 bacteriaRead more about exponential growth at; https://brainly.com/question/15316908

how do i solve this
Answer:
m <E = 134
Step-by-step explanation:
Triangle DEF looks like an isosceles triangle to the base angles are the same measure.
6x+11 = 10x+3
Subtract 11 from both sides
6x = 10x-8
Subtract 10x from both sides
-4x = -8
Divide -4 from both sides
x = 2
Substitute 2 into both equations to make sure it works
6 (2) + 11
12+11
23
10 (2) +3
20+3
23
Both angles equal 23 degrees.
Now subtract both angles from the total angle measure of 180.
180-23-23=134
