Answer:

m = 25 and b = 599

Step-by-step explanation:

the m represents month while the B represent buy that means when he bought a tablet

=> m = 25 and b = 599

     Our m will be 25 because every month she pays $25 for the data plan, increasing it by 25.

     Our b will be 599 because the tablet started out at $599 dollars.

m = 25 and b = 599, the third option

Answer:

≈$12601.72

Step-by-step explanation:

Use the compounded interest formula:

[tex]A = P(1+\frac{r}{n})^{nt}[/tex]

In our case,

P = 3000

r = 8% = 0.08

n = 12 (months per year)

t = 18 (years in total)

Therefore, A ≈ $12601.72 (2.d.p.)

Suppose ABC be a triangle such that ∠A = 4x + 7 ,

∠B = 3x + 5 & ∠C = 6x + 12

We know, the sum of interior angles of a Triangle is 180°, therefore, ∠A + ∠B + ∠C = 180°

or, 4x + 7 + 3x + 5 + 6x + 12= 180°

or, 13x = 180 - 24

or, x = 156/ 13 = 12

Answer:

Slope m = [tex]\frac{5}{8}[/tex]

Step-by-step explanation:

[tex]x_{1}=-6\\ y_{1}=-4\\\\x_{2}=2\\y_{2}=1\\\\[/tex]

def. of slope = rise over run

[tex]\frac{y_{2}-y_{1} }{x_{2}-x_{2}}[/tex]

so:

[tex]\frac{1-(-4)}{2-(-6)} = \frac{1+4}{2+6} = \frac{5}{8}[/tex]

We get [tex]\frac{5}{8}[/tex] as our slope

The slope of the line in the graph is 5/8.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

As we observe the graph the line is passing from points (-6, -4) and (2, 1)

Slope = 1+4/2+6

=5/8

Hence, the slope of the line in the graph is 5/8.

Answer:

(-1, 16), (3, 12)

These are my examples so if you want you can do different solutions, too!

Step-by-step explanation:

It may sound weird, but there are infinitely many solutions to a linear equation. It's basically all real numbers that are on the line.

So, just choose two random numbers for the x-value and substitute in into the equation. I'm going to use -1 and 3.

x = 15 - y

when x = -1

-1 = 15 - y

y = 16

(-1, 16)

when x = 3

3 = 15 - y

y = 12

Answer:  approximately 7525 feet

A more accurate value is 7,524.6679636332 feet, but even that isn't fully exact.

==========================================================

Explanation:

The change in height, or delta height value, is 11200-9000 = 2200 which is the vertical component of the right triangle shown below. This side is opposite the reference angle, aka the angle of elevation 17°

The hypotenuse is x, which is the length of the trail. Assume we're dealing with a flat and straight surface. Of course realistically the ground is very likely going to be bumpy with various curved complexities; but we'll simplify things greatly.

We'll use the sine ratio to find x.

sin(angle) = opposite/hypotenuse

sin(17) = 2200/x

x*sin(17) = 2200

x = 2200/sin(17)

x = 7,524.6679636332

Assuming your teacher wants you to round to the nearest whole number, then we'd get to 7525 feet

We need Hypotenuse

[tex]\\ \rm\rightarrowtail sin\theta=\dfrac{Perpendicular}{Hypotenuse}[/tex]

[tex]\\ \rm\rightarrowtail sin17=dfrac{2200}{h}[/tex]

[tex]\\ \rm\rightarrowtail h=2200/sin17[/tex]

[tex]\\ \rm\rightarrowtail h=2200/0.2923[/tex]

[tex]\\ \rm\rightarrowtail h=7526.51ft[/tex]

Answer:

See explanation below.

Step-by-step explanation:

First I'm going to find angle 2. Angle two plus 55 is equal to 115. 180-115=65. 65-55=10 Angle 2 = 10

Next, we can find angle 3. 55+10=65. 180-65=115. Angle 3 = 115

Angle 2 is equal to angle 5, angle 3 is equal to angle 6, and angle 4 is equal to 55.

Angle 5 = 10

Angle 4 = 55

Angle 6 = 115

Now we can find angle 8. 180-115=65. Angle 8 = 65

Angle 11 = 65

Angle 12 = 115

10+115=125 Angle 10 = 125

180-125 = 55 Angle 9 = 55

Angle 14 = 55

Angle 13 = 125

Answer:

<8, <5, <10 are 65 degrese

Step-by-step explanation:

oki, so, 55+m<2 must be 115 because 115 is a corresponding angel to 55+<2 meaning they are =, so m<2=115-55, m<2=60.

m<3 must then = 65 because line a phase a 180 angle (assuming a and b are parallel)

<3 is also corresponding to angle <10 so by the transitive property m<10=65.

m<8 must then = 65 because the angle of line b in 180, and the transversal cuts 115, 180-115=65.

whoops, then finally 5 is vertical from <2 so it is congruent, so <2 must be 65, so all angles are 65 degrees.

Answer:

The smaller number is 23.

The bigger number is 131.

Step-by-step explanation:

"difference" means subtraction. In this question "more than" means adding. This can be done with one variable. And would take more reasoning with the meaning of the words, but less complicated algebra.

If you are learning systems of equations in high school or college, then you may want to use two variables. The set up is way more straight forward. But then you also need strategies to solve a system of equations.

There are two solutions attached. You only need one that matches the math you are studying. see images.

Answer:

it can be simplified to Y^(-5)X^(-2)

Step-by-step explanation:

So the exponents can be added because the terms are all being multiplied:

For Y: (-8)+(3)=(-5)

For X: (0)+(-2)=(-2)

So the simplified answer is Y^(-5)X^(-2)

That is also the same as 1/[(x^5)(y^2)]

Answer:

Step-by-step explanation:

[tex]y''+4y'+4y=0,\:y(0)=1,\:y'(0)=1\\\\m^2+4m+4=0\\\\(m+2)(m+2)=0\\\\m=-2[/tex]

Thus, since we have equal real roots, we use the general solution [tex]y(x)=C_1e^{m_1x}+C_2e^{m_1x}[/tex] and our initial conditions to set up our system of equations:

[tex]y(x)=C_1e^{-2x}+C_2e^{-2x}\\\\y(0)=C_1e^{-2(0)}+C_2e^{-2(0)}\\\\1=C_1+C_2[/tex] <-- First one

[tex]y(x)=C_1e^{-2x}+C_2e^{-2x}\\\\y'(x)=-2C_1e^{-2x}-2C_2e^{-2x}\\\\y'(0)=-2C_1e^{-2(0)}-2C_2e^{-2(0)}\\\\1=-2C_1-2C_2[/tex] <-- Second one

Solve the system

[tex]C_1+C_2=-2C_1-2C_2\\\\3C_1+3C_2=0\\\\3C_1=-3C_2\\\\C_1=-C_2[/tex]

[tex]1=C_1+C_2\\\\1=-C_2+C_2\\\\1=0[/tex]

Therefore, there are no solutions to the differential equation given the initial conditions.

Answer:

x=3

Step-by-step explanation:

we can use the  pythagora thearom as it is a right angled triangle.

[tex]a^{2} +b^{2} =c^{2}[/tex]

so in this example it would be like this

[tex]x^{2} +x^{2} =(3\sqrt{2})^{2}[/tex]

so lets simplify it to this

[tex]2x^{2} =18[/tex]

now all thats left is to get x on its own

[tex]x^{2} =9[/tex]

[tex]x=+or-3[/tex]

Answer:

(x, y) ==> (-4, -3)

Step-by-step explanation:

-2(3x + y = -15) ==> -6x - 2y = 30

3x + 2y = -18

-6x - 2y = 30

3x + 2y = -18

-3x = 12

/-3    /-3

x = -4

Now, we solve for y:

-6x - 2y = 30

-6(-4) - 2y = 30

24 - 2y = 30

-24        -24

-2y = 6

/-2    /-3

y = -3

(x, y) ==> (-4, -3)

Hope this helps!
