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!!

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

Answer:

4a) Irrational

Step-by-step explanation:

The square root of 20 is irrational. There is no number that can multiplied by itself to equal 20.

For a better explanation, the square root of 25 is rational. 5 can be multipled two times to be equivalent to it. Meanwhile, 20 can't.

Answer:

$76.95

Step-by-step explanation:

If you reverse it the equation is 16.93 divided by .22 and you get the total which is 76.95

You can check your answer by doing 76.95 times .22 and get the tip which is 16.93

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

the answer for this equation is 499 + 199 equals 599

Answer:

11

Step-by-step explanation:

If you're at 8 and move 3 to the right in a number line, you would end up at 11.

Answer:

See explanation

Step-by-step explanation:

a.   [tex]\int\limits^4_1 {(f + g)(x)} \, dx = \int\limits^4_1 {f(x)} \, dx + \int\limits^4_1 {g(x)} \, dx = 11 + 17 = 28[/tex]

b.  [tex]\int\limits^6_4 {f(x)} \, dx = \int\limits^6_1 {f(x)} \, dx - \int\limits^4_1 {f(x)} \, dx = 23 - 11 = 12[/tex]

c.  [tex]\int\limits^4_1 {3f(x)} \, dx = 3\int\limits^4_1 {f(x)} \, dx = 3(11) = 33[/tex]

d.  [tex]\int\limits^4_1 {(g(x) + 2)} \, dx = \int\limits^4_1 {g(x)} \, dx + \int\limits^4_1 \, 2dx = 17 + (8 - 2) = 17 + 6 = 23[/tex]

Answer:

Hello Love! The median is simply just the number in the middle so sense we have 2 numbers in the middle our median will be 3 and 6

The mean is when you add up the numebers then divide by how many numbers there are so...

3 + 2 + 4 + 6 + 3 + 6 + 1 + 2 + 5 + 4 = 36 so 36 divided by 10 is 3.6

The range is simply just the biggest number in the sequence subtracted by the smallest number so... 6 - 1 = 5 so 5 would be our range!

Hope this helps you.

Answer:

55°

Step-by-step explanation:

Let the centre of the circle be C

mFG=110 (It's hard to read but I assume thats what the 110 marks)

mFG=<FCG=110

Consider ΔFCG (an isosceles triangle since CF=CG=radius). Angles in a triangle add to 180 and <CFG=<CGF so <CFG=(1/2)(180-110)=(1/2)(70)=35°

<EFG+<CFG=90

<EFG+35=90

<EFG=55°

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.
