Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

y = 2x - 1

y = -3x + 4

Step 2: Solve for x

Substitution

Substitute in y:                   2x - 1 = -3x + 4Add 3x on both sides:       5x - 1 = 4Add 1 to both sides:           5x = 5Divide 5 on both sides:     x = 1
Answer 2

Answer:

[tex]y = 2x - 1 \: and \: y = - 3x + 4 \\replacing \: the \: value \: of \: y, \: we \: get \\ 2x - 1 = - 3x + 4 \\ 5x = 5 \\ \boxed{x = 1}[/tex]

x= 1 is the right answer.

Ulio is running in a 13.1-mile race. There are water stops every 2.75 miles along the route from the beginning of the race. What is the distance between the last water stop and the end of the race? Enter your answer in the box.

Answers

Answer:

2.1 miles

Step-by-step explanation:

Given that :

Total distance = 13.1 miles

Distance between each water stop = 2.75 miles

Distance between last water stop and end of the race

We need to find the maximum number of water stops :

Total miles / distance between water stops

13.1 / 2.75

= 4.763

Maximum number of water stops = 4

Distance to last water stop = 4 * 2.75 = 11 miles

Hence, distance between last water stop and end of Race :

Total miles - distance to last water stop

13.1 miles - 11 miles

= 2.1 miles

Two sides of a triangle can be represented by the expressions 3x+8 and 2x2-4x+5.If the perimeter of the triangle is 4x2+2x-10, what expression can be used to represent the third side?

Answers

Answer:

s = 2x²+3x-23

Step-by-step explanation:

Given that,

First side of a triangle = 3x+8

Second side of a triangle = 2x²-4x+5

The perimeter of the triangle = 4x²+2x-10

We need to find the expression for the third side. Let the third side b s.

Perimeter = Sum of all sides

4x²+2x-10 = 3x+8 + 2x²-4x+5 +s

4x²+2x-10 = 2x²-x+13+s

s = 4x²+2x-10- (2x²-x+13)

= 2x²+3x-23

So, the third side will be 2x²+3x-23.

Answers

Answer:

Option B

Step-by-step explanation:

Length of the rectangular sand box is given by the function,

F(x) = 3x³ + 6x - 2

Width of the sand box is represented by the function,

W(x) = 2x² - 4

Area function for the sand box will be,

Area of a rectangle = Length × Width

F(x) × W(x) = (3x³ + 6x - 2)(2x² - 4)

                 = 2x²(3x³ + 6x - 2) - 4(3x³ + 6x - 2)

                 = 6x⁵+ 12x³ - 4x²- 12x³- 24x + 8

                 = 6x⁵- 4x²- 24x + 8

Therefore, Area function will be represented by a polynomial degree of 5.

Option B will be the answer.

Alex constructs a scatter plot. He realizes that he needs to add one more point, which will be an outlier. Which of the ordered pairs does he still need to plot? (14,2) (2,12) (18,10) (10,6)

Answers

Answer:

(14,2)

Step-by-step explanation:

Have took the test

(14,2) is an outlier of the constructed scatter plot.

What is scatter plot?

A scatter plot is a set of points plotted on a horizontal and vertical axes. Scatter plots are important in statistics because they can show the extent of correlation, if any, between the values of observed quantities or phenomena (called variables).

Given that, Alex constructs a scatter plot. He realizes that he needs to add one more point,

As we know If one point of a scatter plot is farther from the regression line than some other point, then the scatter plot has at least one outlier. If a number of points are the same farthest distance from the regression line, then all these points are outliers.

Here, When we will plot each of the points, and we will find that (14, 2) is the furthest away from the scatter

Hence, (14,2) is an outlier of the constructed scatter plot.

Answers

Answer:

because 54 is correct answer.

The value of surface area of the right cone is,

⇒ 54π units²

What is Multiplication?

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Radius of cone = 3 units

Slant height = 15 units

Now, The formula for the total surface area of a right cone is,

T. S. A = πrl + πr²

Hence, We get;

The value of surface area of the right cone is,

⇒ π x 3 x 15 + π x 3²

⇒ 45π + 9π

⇒ 54π units²

Thus, The value of surface area of the right cone is,

⇒ 54π units²

write the equation of a line perpendicular to 2y+x=4 and passes through the point (2,1) ​

Answers

Answer:

Por favor, dame una captura de pantalla de la pregunta No entiendo esto gracias

Answer:

[tex]-2x+y=-3[/tex]

Step-by-step explanation:

Recall perpendicular lines have negative-reciprocal slopes. Since the equation [tex]2y+x=4[/tex] has a slope of [tex]-\frac{1}{2}[/tex] ([tex]y=-\frac{1}{2}x+2[/tex]), any line perpendicular to it will have a slope of [tex]-\frac{1}{-\frac{1}{2}}=2[/tex].

Therefore, we have the line:

[tex]y=2x+b[/tex] where [tex]b[/tex] is the y-intercept.

We can plug in the point it passes through to find the final equation:

[tex]1=2(2)+b,\\b=1-4,\\b=-3[/tex].

Therefore, the equation of the line perpendicular to  [tex]2y+x=4[/tex] that passes through the point [tex](2, 1)[/tex] is:

[tex]y=2x-3[/tex] (slope-intercept form)

However, since the initial line given is in standard form, re-write this equation to standard form:

[tex]y=2x-3,\\y-2x=-3,\\\fbox{$-2x+y=-3$}[/tex].
