Answer:

98

Step-by-step explanation:

m<KJU + m<UJI = m<KJI

this equation will help us find the value of x therefore the value of m<KJU

Rewrite the equation using the expressions

104 + x + x + 76 = 168 add like terms

180 + 2x = 168 subtract 180 from both sides

2x = -12 divide both sides by 2

x = -6 to find the value of m<KJU replace x with -6

104 + (-6) = 98

The graph at option 1 shows the given inequality y < x² + 1. The domain and range of the given inequality is {x: x ∈ (-∞, ∞)} and {y: y ∈ [1, ∞)}.

The steps to graph an inequality equation are:

The given inequality is y < x² + 1

Finding points to graph the boundary line by taking y = x² + 1:

When x = -2,

y = (-2)² + 1 = 4 + 1 = 5

⇒ (-2, 5)

When x = -1,

y = (-1)² + 1 = 2

⇒ (-1, 2)

When x = 0,

y = (0)² + 1 = 1

⇒ (0, 1)

When x = 1,

y = (1)² + 1 = 2

⇒ (1, 2)

When x = 2,

y = (2)² + 1 = 5

⇒ (2, 5)

Plotting these points in the graph forms an upward-facing parabola.

So, all the points above the vertex of the parabola satisfy the given inequality. Thus, that part is shaded.

From this, the graph at option 1 is the required graph for the inequality y < x² + 1. The boundary line is dashed since the inequality symbol is " < ".

What is the equation of a line?

Let the first point be = (x₁ , y₁)

Let the second point be = (x₂ , y₂)

m(slope) = (y₂ - y₁) / (x₂ - x₁)

Equation of line = (y - y₁) = m(x - x₁)

Let the no. of miles be plotted on X-axis

Let the driving time be plotted on Y-axis

First point = (61 , 41)

Second point = (42.3 , 63)

Slope of the linear function = (63 - 41)/(42.3 - 61) = -1.17

Equation of the line = (y - 41) = -1.17(x - 61)

Given time of driving = 81 min

Number of miles = (81 - 41) = -1.17(x - 61)

40/-1.17 = x - 61

-34.18 + 61 = x

Step-by-step explanation:

You are given coordinate values and a formula that tells you what to do with them. All you need to do is put the values in the formula and do the arithmetic.

You are given points (2, -3) and (6, 4). The slope formula refers to the two points as (x1, y1) and (x2, y2). It does not matter which is which.

If we use the points in the same order they are given, then we can see that ...

It looks like the equation is

[tex]\dfrac{du}{dt} = 2t + \dfrac12 \sec^2(t) u[/tex]

with initial value [tex]u(0) = \frac\pi2[/tex].

Rearrange the equation to

[tex]\dfrac{du}{dt} - \dfrac12 \sec^2(t) u = 2t[/tex]

Multiply both sides by the integrating factor

[tex]\displaystyle \mu = \exp\left( \int -\frac12 \sec^2(t)\,dt\right) = \exp\left(-\frac12\tan(t)\right)[/tex]

and solve for [tex]u[/tex].

[tex]\implies e^{-\frac12 \tan(t)} \dfrac{du}{dt} - \dfrac12 \sec^2(t) e^{-\frac12 \tan(t)} u = 2t e^{-\frac12 \tan(t)}[/tex]

[tex]\implies \dfrac{d}{dt}\left[e^{-\frac12 \tan(t)} u\right] = 2t e^{-\frac12 \tan(t)}[/tex]

By the fundamental theorem of calculus, integrating both sides yields

Answer:

d: y=5x

Step-by-step explanation:

Since we know a few points: (2,10), (3,15), (4,20), we can use two of them to first find the slope. The equation for the slope is (Increase in y)/(increase in x).

1. Slope between (2,10) and (3,15) is 5/1 which is 5. So the slope will be 5.

2. With the slope, we know that our equation will be: y=5x+b. To find b, we can replace x and y with another point. 20 = 5(4)+b. --> 20 = 20 +b. Now we know that b equals 0.

Our final equation will be y = 5x.

RECHECKING!

I'll recheck whether my answer is right or not using Desmos (A online graphing calculator).

I added an image down below, and I drew the points in blue. This shows that since the graph crosses all three points, it is correct.

WHY y=1/5x IS NOT CORRECT (based on your comments)

If you look at the points, the relationship between x and y is not 1/5. If you multiply something from x, it should become 10.

--> 2 times __ = 10

--> 3 times __ = 15

--> 4 times __ = 20

And clearly, __ will be 5. If it becomes 1/5, we won't get the right number of y.

This is why y=1/5 is not correct.

If the growth rate of bacteria at any time is proportional to the number of bacteria present at t then the population after 20 weeks will be 403.42[tex]x_{0}[/tex] in which [tex]x_{0}[/tex] is the initial population.

Given that the growth rate of bacteria at any time t is proportional to the number present at t and triples in 1 week.

We are required to find the number of bacteria present after 10 weeks.

let the number of bacteria present at t is x.

So,

dx/dt∝x

dx/dt=kx

1/x dx=k dt

Now integrate both sides.

[tex]\int\limits {1/x} \, dx[/tex]=[tex]\int\limits{k} \, dt[/tex]

log x=kt+log c----------1

Put t=0

log [tex]x_{0}[/tex]=0 +log c    ([tex]x_{0}[/tex] shows the population in beginning)

Cancelling log from both sides.

c=[tex]x_{0}[/tex]

So put c=[tex]x_{0}[/tex] in 1

log x=kt+log [tex]x_{0}[/tex]

log x=log [tex]e^{kt}[/tex]+log [tex]x_{0}[/tex]

log x=log [tex]e^{kt}x_{0}[/tex]

x=[tex]e^{kt}x_{0}[/tex]

We have been given that the population triples in a week so we have to put the value of x=2[tex]x_{0}[/tex] and t=1 to get the value of k.

2[tex]x_{0}[/tex]=[tex]e^{k} x_{0}[/tex]

2=[tex]e^{k}[/tex]

log 2=k

We have to now put the value of t=20 and k=log 2 ,to get the population after 20 weeks.

x=[tex]e^{20log 2}[/tex][tex]x_{0}[/tex]

x=[tex]e^{0.30*2}[/tex][tex]x_{0}[/tex]

x=[tex]e^{6}x_{0}[/tex]

Line: y = 3x + 3

Point: (7,3)

Discussion

The easiest variation on line problems is one like this one. The reason is that all you need do is read the slope of the given line.

m = 3 of the given line. Also the slope of the new line.

What you have so far is

y = 3x + b

The point is used to find b -- the y intercept.

x = 7

y = 3

You are not given this, but what you want to think is that when x = 7, y = 3

Substitute into the new equation

3 = 3*7 + b

3 = 21 + b                         Subtract 21 from both sides.

3 - 21 = 21-21 + b

- 18 = b

Answer:

-2/3x+23/3

Step-by-step explanation:

y= mx+c

where

m is the slope c is the y-intercept.

1-getting the slope:

we are given that the line we are looking for is parallel to the line

y=-2/3x+3

this means that the slope of the two lines are equal . comparing the general formula with the given line , we would find that the slope of the given lines -2/3.this means that the slope of the lines we are looking for is also -2/3

The equation of the line now becomes:y=-2/3x+c

2-getting the value of c

to get the value of c, we will use a point that belongs to the line (7,3),substitute in the equation and solve for c as follows:

y=-2/3x+c

3=(-2/3)(7)+c

3=-14/3+c

c=3+14/3

c=23/3

Based on the above, the equation of the line we are looking for is:

y=-2/3x+23/3

The explanation for the question was written in my other response.

Answer:

d.  m = 15c

Step-by-step explanation:

Directly proportional means as one amount increases, another amount increases at the same rate.

Proportionality can be used to set up an equation.

Given variables:

If m is directly proportional to c then:  [tex]m \propto c[/tex]

Convert this to an equation by using a constant of proportionality, k:

[tex]\implies m=kc[/tex]

We are told that Paul washed 8 cars and earned $120.

Substitute these values into the found equation and solve for k:

[tex]\implies 120=8k[/tex]

[tex]\implies k=\dfrac{120}{8}[/tex]

[tex]\implies k=15[/tex]

Finally, substitute the found constant of proportionality (k) into the equation:
