Answer:

y=2x-2

Step-by-step explanation:

The slope is 2 and your y intercept is already given as -2.

Slope intercept is basically y=mx+b

plug it in so you get y=2x-2

Answer:

Step-by-step explanation:

sinθ = 3/12 = 0.25

θ = arcsin(0.25) ≈ 14.5°

If person travelled 12 metres on hill and have risen in height by 3 metres then the gradient of this problem is 14.5°.

Gradient is the degree of inclination or the rate of ascent or descent.It is an inclined surface, grade, ramp.

The hill and the road through which person travelled forms a right angled triangle. In a right angled triangle sin a is equal to Perpendicular/Hypotenuse where a is angle opposite to perpendicular.

In this we have to apply the above rule:

sin a=3/12

sin a=1/4

sin a=0.25

a= [tex]sin^{-1}[/tex]0.25

a=14.5

Hence the gradient of the problem is 14.5°.

Answer:

x= −4 /3  y+  2/ 3

Step-by-step explanation:

Answer:

First write it as 0.03 × $4,000. Then multiply 3 × $4,000 = $12,000. Lastly put the decimal point where it gives the answer two decimal digits: $120.00.

Step-by-step explanation:

Answer:

3% of 4,000 = 120.

Step-by-step explanation:

To find the answer we have to divide 3 by 100, which equals 0.03.  Now multiply 0.03 by 4,000 and we get 120.  Therefore, 120 is our answer.

[tex]Each =\pounds 1121[/tex]

Step-by-step explanation:

See comment for complete question.

Given

[tex]Total = \pounds 8968[/tex]

[tex]Projects = 8[/tex]

Required

Determine the amount allotted to each

From the question, we understand that each project gets each allocation.

So, the amount of each is:

[tex]Each =\frac{Total}{Projects}[/tex]

[tex]Each =\frac{\pounds 8968}{8}[/tex]

[tex]Each =\pounds 1121[/tex]

Each project gets £1121

Step-by-step explanation:

The solution is,  the measure of ∠ZYC is 108 degrees.

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle. The two rays are called the sides of an angle, and the common endpoint is called the vertex.

here, we have,

Given:

m∠XYZ = 72 degrees

m∠XYZ and m∠ZYC form a linear pair.

Let's find the measure of ∠ZYC.

To find the measure of angle ZYC, apply the Linear Pair of Angles theorem which states that the sum of angles that form a linear pair is 180 degrees.

Hence, we have:

m∠XYZ + m∠ZYC = 180

72 + m∠ZYC = 180

• Subtract 72 from both sides:

72 - 72 + m∠ZYC = 180 - 72

m∠ZYC = 180 - 72

m∠ZYC = 108 degrees.

Therefore, the measure of ∠ZYC is 108 degrees.

Answer:

Dad=35, Son=15

Step-by-step explanation:

Well since the dad is 20 year older then the son we can call the son x and the dad x+20. Now five years ago the father was 3 times older then the so we construct the following equation:

x+20−5=3(x−5)

x+15=3x-15

x=15

So now we know that the sons age is 15 meanimg that since the dads 20 years older then him, his age is 20+15 which is 35!

I deposit $500 in my bank from my check this week. I have to withdraw $550 from my bank to pay my medical bills. I am short -55/55 dollars so I wait to pay my medical bills.

Answer:

9 mph

Step-by-step explanation:

Speed of current = 6 mph

Distance to travel one way = 22.5 miles

Let speed of the ferry be [tex]x[/tex] mph

Total time taken for round trip is 9 hours

One way the ferry will be going with the current and in the other way the ferry will be going against the current so

[tex]\dfrac{22.5}{x+6}+\dfrac{22.5}{x-6}=9\\\Rightarrow \dfrac{x-6+x+6}{x^2-36}=\dfrac{9}{22.5}\\\Rightarrow \dfrac{2x}{x^2-36}=0.4\\\Rightarrow \dfrac{2x}{x^2-36}-0.4=0\\\Rightarrow 2x-0.4x^2+14.4=0\\\Rightarrow 0.4x^2-2x-14.4=0\\\Rightarrow 4x^2-20x-144=0\\\Rightarrow x=\dfrac{-\left(-20\right)\pm \sqrt{\left(-20\right)^2-4\times 4\left(-144\right)}}{2\times 4}\\\Rightarrow x=9,-4[/tex]

So, the speed of the boat in still water needs to be 9 mph both ways.
