Answer:

y value is proportional to the x values change

Step-by-step explanation:

the slope of the line can be anything but if it is a line then it isn't a function that produces like an exponential curve. whatever the slope, the input x value will always produce a y value to a consistent extent.

Answer:

To graph a straight line:

find the y-intercept by taking x = 0

find the x-intercepts by taking y = 0

Draw a straight line joining these two points

change in y depends on the slope.

As x increases:

y increases if the slope is positive

y decreases if the slope is negative

As x decreases:

y increases if the slope is negative

y decreases if the slope is positive

Answer:

a): A line has a total degree of 180. So just subtract it. 180-92 is

y=88

b): Similar to the previous, a right angle has a total angle of 90. 90-45=45.

y=45.

These are all the ones I can figure out. I hope someone else can get c) and d).

ASAP!! Find the length of side x in simplest form with a rational denominator

lidiya [134]

Answer:

$x=\sqrt{14}$

Step-by-step explanation:

This triangle is a 45-45-90 triangle.

By using the image I posted, we can find x easily.

So, we have $\sqrt{7}$ as one of the sides.

They hypotenuse, which is x is just $\sqrt{7} \sqrt{2}$

Simplify and we get x = $\sqrt{14}$

Please help me do it

Step-by-step Explanation:

We are going to solve this problem using integration by parts. We can write the integrand as

$\dfrac{4x}{x^2+4x+3} = \dfrac{4x}{(x+3)(x+1)}$

$\:\:\:\:\:\:\:\:\:\:\:\:\:= \dfrac{A}{x+3} + \dfrac{B}{x+1}$

$\:\:\:\:\:\:\:\:\:\:\:\:\:= \dfrac{Ax + A + Bx + 3B}{x^2+4x+3}$

$\:\:\:\:\:\:\:\:\:\:\:\:\:=\dfrac{(A+B)x + (A+3B)}{x^2+4x+3}$

Comparing the above term to the left hand side, we can see that

(A + B)x = 4x

A + 3B = 0

Solving for A and B, we find that A = 6 and B = -2 so our integrand becomes

$\dfrac{4x}{x^2+4x+3} = \dfrac{6}{x+3} - \dfrac{2}{x+1}$

We can now easily integrate this expression as follows:

$\displaystyle \int{\dfrac{4x}{x^2+4x+3}}dx = 6\int{\dfrac{dx}{x+3}} - 2\int{\dfrac{dx}{x+1}}$

$\:\:\:\:\:\:\:\:\:\:\:\:\:= 6\ln|x+3| - 2\ln|x+1| + C$

the sum of four times a number and eight is between zero and twelve. find the range of numbers. write a compound inequality.

Masja [62]

Let the number be the variable x

4 times the number is 4x

the sum of 8 and 4 times a number is 28

4x+8=28

4x=28-8

4x=20

x=20/4

x=5
