A line l2 is perpendicular to the line x + 2y – 5 = 0 without computing the gradient of this
line find the equation of l2 if it passes through (3, 4)
Answer:
y=2x-2
Step-by-step explanation:
first, let's put the line into y=mx+b form (slope-intercept form), where m is the slope (or gradient) and b is the y intercept
add 5 to both sides
x+2y=5
subtract x from both sides
2y=-x+5
divide by 2
y=-1/2x+5/2
perpendicular lines have slopes (gradients) that are negative (one is positive, another one is negative) and reciprocal (they are essentially the same number, just "flipped")
to find the slope of I2:
since -1/2 is negative, that means the slope of I2 will be 2 (2/1 is the reciprocal of 1/2 (positive version of -1/2))
so here's our equation so far:
y=2x+b
now we need to find b
because line will pass through (3,4), we can use it to solve for b
substitute 4 as y and 3 as x
4=2(3)+b
multiply
4=6+b
-2=b
therefore the equation is y=2x-2
hope this helps!!

Pls answer this for me. How many paving stones, each 1m long and 80cm wide, are needed to cover a compound 13.6m long and 11m wide?
Answer:
187 paving stones are needed
Step-by-step explanation:
Given
Paving stone
[tex]Length = 1m; Width = 80cm[/tex]
Compound
[tex]Length = 13.6cm; Width = 11m[/tex]
Required
Number of wires to cover the compound
Area is calculated as:
[tex]Area = Length * Width[/tex]
For the paving stone, we have:
[tex]A_1 =1m * 80cm[/tex]
Convert cm to m
[tex]A_1 =1m * 0.80m[/tex]
[tex]A_1 =0.8m^2[/tex]
For the compound, we have:
[tex]A_2 = 13.6m * 11m[/tex]
[tex]A_2 = 149.6m^2[/tex]
Divide the area of the compound by the area of the paving stone
[tex]n = \frac{A_2}{A_1}[/tex]
[tex]n = \frac{149.6}{0.8}[/tex]
[tex]n = 187[/tex]

your backyard is shaped like a rectangle and measure's 45 1/2 feet by 50 feet. you want to put a fence around your backyard. how much fence will you need?
Answer:
191 ft
Step-by-step explanation:
If it's 45.5ft x 50ft, we'll need to put fence around two 45.5ft sides and two 50ft sides.
2*45.5ft + 2*50ft = 91ft + 100ft = 191ft

Answer: C. (-2, 0)
Step-by-step explanation:
5x+6y=-10 3x-2y=-6Now you need to get -2 to equal -6 so it cancels out5x+6y=-10 3(3x-2y)=3(-6)Then distribute the 35x+6y=-10 9x-6y=-18Now add the equations together14x=-28 Now solve for x: Divide both sides by 14x=-2Plug x into either equation to solve for y.3(-2)-2y=-6Distribute -2-6-2y=-6 Add 6 to both sides6 cancels out leaving: -2y=0Divide both sides by -2y=0So, the answer is (-2, 0)! Hope this helps
what are the missing numbers?
Given:
The table of values of an exponential function.
To find:
The missing values in the exponential function.
Solution:
The general exponential function is defined as:
[tex]y=a(b)^x[/tex] ...(i)
Where, a is the initial value and b is the growth factor.
First point from the given table is (1,10). It means, the equation (i) must be true for (1,10).
[tex]10=a(b)^1[/tex] ...(ii)
Second point from the given table is (2,20). It means, the equation (i) must be true for (2,20).
[tex]20=a(b)^2[/tex] ...(iii)
Dividing (iii) by (ii), we get
[tex]\dfrac{20}{10}=\dfrac{a(b)^2}{ab}[/tex]
[tex]2=b[/tex]
Putting [tex]b=2[/tex] in (ii), we get
[tex]10=a(2)^1[/tex]
[tex]\dfrac{10}{2}=a[/tex]
[tex]5=a[/tex]
Putting [tex]a=5,b=2[/tex] in (i), we get
[tex]y=5(2)^x[/tex]
The required exponential function for the given table of values is [tex]y=5(2)^x[/tex]. So, the missing values are 2 and x, where 2 is in the base and x is in the power.

Answer:
x = 5, y = -3
Step-by-step explanation:
2x - 3y = -1 ---› Eqn. 1
-2x + y = 7 ----› Eqn. 2
Add both equations
-2y = 6
Solve for y
y = 6/-2
y = -3
Substitute y = -3 into Eqn. 1.
2x - 3(-3) = -1
2x + 9 = -1
2x + 9 - 9 = -1 - 9
2x = -10
2x/2 = -10/2
x = 5
Solution: x = 5, y = -3

Let's solve your inequality step-by-step.
−1 / 3 x + 1 / 2 < 3.5
Step 1: Subtract 1/2 from both sides.
−1 / 3 x + 1 / 2 − 1 / 2 < 3.5 − 1 / 2
−1 / 3 x < 3
Step 2: Multiply both sides by 3 / ( -1 ).
( 3 / −1 ) * ( −1 / 3 x ) < ( 3 / −1 ) * ( 3 )

a
31.68
b
29.31
23.14
17.79
Answer:
b = 29.31
Step-by-step explanation:
Given:
m<CEB = 68°
EB = radius = 15
Required:
Length of arc CD
Solution:
Length of arc CD = θ/360 × 2πr
Where,
θ = 180° - 68° = 112° (angles on a straight line)
π = 3.14
r = radius = 15
Plug in the values
Length of arc CD = 112/360 × 2 × 3.14 × 15
= 29.3066667
≈ 29.31
