Please help me with this!! ***BRAINLIEST IF 2 PPL ANSWER**

Mathematics

Answer:


Step-by-step explanation:

Problem One

19 + 2*ln(x) = 25                  Subtract 19 from both sides

19 - 19 + 2ln(x) = 25 - 19      Combine

2* ln(x) = 6                           Divide by 2

ln(x) = 3                                Take the inverse log

e^(ln(x)) = e^3                       Reduce

x = 20.09

Problem 2

Getting this to graph in Desmos can be a bit of trouble.  The correct format is y = abs(x^2 - 3x + 1). Knowing about abs and getting the quadratic to work are two separate [and difficult] problems.

The graph for this is below.

The answers (according to Desmos) are (2,1) and (3.4, 2.4). I think you should include D but that is a matter of opinion. I think it's a typo. Whoever made the question up may actually get that answer.

Solve this system of linear equations.separate the x- and y-value with a comma. -6x=-4-y -7x=-22+y.
scZoUnD [109]

Answer:

(2,8)

Step-by-step explanation:

Add them together to get rid of the y.

-6x = -4 - y

-7x = -22 + y

=

-13x = -26

Then solve for x.

-13x/-13 = -26/-13

x = 2

Now plug in the x value into either equation and solve for y.

-7(2) = -22 + y

-14 = -22 + y

-14 + 22 = -22 + 22 + y

8 = y

So...

x = 2

y = 8

(2,8)

What is the poinet-slope form of the equation for the line in the graph?​
Ne4ueva [31]

Answer:

y -5 = \frac{9}{13}(x - 7)

Step-by-step explanation:

Given :

Two points are given in graph (-6, -4) and {7, 5).

The point-slope form of the equation of a straight line is:

y -y_{1} = m(x - x_{1})------------(1)

Let (x_{1}, y_{1})=(7,5) and (x_{2}, y_{2})=(-6,-4)

The slope of the line m=\frac{y_{2}- y_{1}}{x_{2}- x_{1}}

Put all known value in above equation.

m=\frac{-4- 5}{-6- 7}

m=\frac{-9}{-13}

m=\frac{9}{13}

The slope of the line m=\frac{9}{13}

We know m, and also know that (x_{1}, y_{1})=(7,5), so we put these value in equation 1.

y -5 = \frac{9}{13}(x - 7)

Therefore, the equation of the line is y -5 = \frac{9}{13}(x - 7).

Answer quick please,
lbvjy [14]

Answer:

132 minutes

Step-by-step explanation:

1 Km = (60)(8)+15=495 seconds

4 mornings = (495)(4) =1980 seconds

4 weeks = (1980)(4) = 7920 sec.

7920/60 = 132 minutes

The can shown has a diameter of 3 inches and a height of 5 inches. Find the lateral surface area of the can.
beks73 [17]

Answer:

Lateral surface area of can = 47 inch² (Approx.)

Step-by-step explanation:

Given:

Diameter of given can = 3 inches

Height of given can = 5 inches

Find:

Lateral surface area of can

Computation:

Radius of can = 3 / 2 = 1.5 inch

Lateral surface area of can = Lateral surface area of cylinder

Lateral surface area of cylinder = 2πrh

Lateral surface area of can = 2πrh

Lateral surface area of can = 2(3.14)(1.5)(5)

Lateral surface area of can = 47.1

Lateral surface area of can = 47 inch² (Approx.)
