Answer:

The slope of line c is 1

Step-by-step explanation:

The given information are;

The coordinates of the points on the line a are; (-3, 3) and (3, -3)

The coordinates of the points on the line b are; (-3, -2) and (2, 3)

Line c ║ line b

Line b ⊥ line a

Line c ⊥ line a

Therefore, we have

The slope, [tex]m_c[/tex] of line c is equal to the slope, [tex]m_b[/tex], of line b Definition of parallel lines (The slopes of parallel lines are equal)

[tex]m_c[/tex] = [tex]m_b[/tex]

Therefore, the slope, m, of the line b is given as follows;

[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Where, for line b, (x₁, y₁) = (-3, -2) and  (x₂, y₂) = (2, 3), we have;

[tex]Slope, \, m_b =\dfrac{3-(-2)}{2-(-3)} = \dfrac{3 + 2}{2 + 3} = 1[/tex]

From [tex]m_c[/tex] = [tex]m_b[/tex] = 1, the slope of line c = 1.

The result from subtracting (-x⁴ + 3x³ + 2x² - 1) from (2x⁴ - x² + 5x - 2) is the algebra expression 3x⁴ - 3x³ - x³ + 5x - 3.

We first open the bracket;

(2x⁴ - x² + 5x - 2) - (-x⁴ + 3x³ + 2x² - 1) = 2x⁴ - x² + 5x - 2 + x⁴ - 3x³ - 2x² - 1

then we collect like terms;

(2x⁴ - x² + 5x - 2) - (-x⁴ + 3x³ + 2x² - 1) = 2x⁴ + x⁴ - 3x³ - x² - 2x² + 5x - 2 - 1

(2x⁴ - x² + 5x - 2) - (-x⁴ + 3x³ + 2x² - 1) = 3x⁴ - 3x³ - 3x² + 5x - 3

Therefore, the solution for the subtraction of the expression (-x⁴ + 3x³ + 2x² - 1) from (2x⁴ - x² + 5x - 2) is the algebraic expression 3x⁴ - 3x³ - 3x² + 5x - 3.

Step-by-step explanation:

So now a full triangle is 180°

Since the full triangle is 180°..you have to minus it with 68°and 70°.

[tex]180 - 68 - 70 = 42[/tex]

This is what you will get

Now write the value (42). Now you have the degree for a whole triangle

Since they are asking you to find the outside angle, you have to minus 42 with 180. This because that's a half circle

Full circle=360

Half circle =180

[tex]180 - 42 = 138[/tex]

Hope this is correct and helpful

Answer:

The Point-Slope form is y - 1 = 4 ( x + 1 )

Step-by-step explanation:

First you have to find the slope which is 4. To get that you get 2 points and do rise/run. I chose the 2 points (-2,-3) and (-1,1).

Since the formula for point-slope form is:

y - y1 = m ( x - x1 )

You simply fill in the blanks with the given point which is ( -1 , 1 ).

Therefore, the point-slope form is:

y - 1 = 4 ( x + 1)

Answer:

2/6 = A and 5/6 =B

Step-by-step explanation:

the line is split into 6 segments. so this means each little line is 1/6. if each line is 1/6, 2 lines, which is A, is 2/6 and 5 lines is 5/6. just multiply 1/6 * th number of lines from the start of the line to the letter

The fraction for point A on the number line will be 2/6 and the fraction for point B will be 5/6 respectively.

Parts of an entire or group of items are represented by fractions. Each fraction has two components. The numerator refers to the number at the top of the line. It indicates how many equal portions of the total or collection are taken. The denominator refers to the figure below the line. It displays how many identical things there are in a collection or how many total equal elements there are to a whole.

There are several types of fractions some of them are :

According to the question, the number line is divided into 6 parts. Points A and B are on the number line.

The fraction for point A = 2/6 and,

The fraction for point B = 5/6

Answer:

Infinite solutions

Step-by-step explanation:

First distribute -1/2 to 4x and -10 and get -2x+5

Then plug it into the equation which would be -2x + 5 = 5 - 2x

And that would be 0=0 because they are the exact same but in a different order.

And 0=0 is true so it is infinite.

Answer:

24 in all

Step-by-step explanation:

1,100/45=24

25+20=45

The number of volleyballs are 30, and the number of soccer balls are 20 that the coach can order.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The cost of each volleyball is $20.

And, The cost of each soccer ball is $25.

The coach plans to order at least 50 volleyballs and soccer balls and he can spend a maximum of $1,100.

Now,

Let number of volleyballs = x

Number of soccer balls = y

So, We can formulate;

⇒ x + y = 50

⇒ $20x + $25y = $1100

Solve both equation as;

From equation (i);

⇒ 20x + 20y = 1000

Subtract above equation from (ii), we get;

⇒ 25y - 20y = 1100 - 1000

⇒ 5y = 100

⇒ y = 20

And, x + y = 50

x + 20 = 50

x = 30

Thus, The number of volleyballs are 30, and the number of soccer balls are 20 that the coach can order.

Answer:

34.1 minutes

Step-by-step explanation:

distance= 2miles,time=11 minutes

pace=velocity

velocity= distance/time

V= (2/11) miles/minutes

since the pace is maintained. then,

time taken to run 6.2 miles would be

time=distance/velocity

T= 6.2miles/(2/11)miles/minutes

T= [(6.2×11)/2]minutes

T= 34.1 minutes.

Answer:

Kindly check explanation

Step-by-step explanation:

Given that:

Total point = 818

Let number of 3 point goals = p

Number of 2 point goals = 2p - 69

Number of 1 point = 2p - 69 - 28 = 2p- 97

3p + 2(2p - 69) + 1(2p - 97) = 818

3p + 4p - 138 + 2p - 97 = 818

9p - 235 = 818

9p = 818 + 235

9p = 1053

p = 117

Hence ;

number of 3 point goals = 117

Number of 2 point goals = 2(117) - 69 = 165

Number of 1 point = 2(117) - 97 = 137

[tex]\angle z = 92[/tex]

Answer:

z = 92

Step-by-step explanation:

z = it's opposite angle

You need to figure out another angle in the triangle containing the 42-degree angle.

There are multiple ways to get there, but going from the 95 degree angle is how I will explain.

95 = 42 + 53

So, think the two small triangles are one big triangle.

95 + 39 = 134

180 - 134 = 46

Now back to the smaller one-

42 + 46 = 88

180 - 88 = 92

The opposite angle to z is 92, making z = 92.

Answer:

(a) 9/50=0.18

(b) 12/3000=4×10^-3

The value of x in the triangle is -5

The sum of angles in a triangle is 180 degrees.

So, we have:

x + 35 + 60 + 90 = 180

Evaluate the sum

x + 185 = 180

Subtract 185 from both sides

x = -5

Hence, the value of x in the triangle is -5

Answer:

The value of the y-coordinate is -706

Step-by-step explanation:

The equation of a straight line is;

y = mx + c

where m is slope and c is t-intercept

Given the slope, we can write the equation as;

y = -79x + c

we need to get c

Just put in the x and y values of the given point

X = -6 and y = 5

5 = -79(-6) + c

5 = 474 + c

c = 5-474 = -469

So the complete equation of the line would

be ;

y = -79x - 469

To get the y-coordinate of the point, just insert the x value into the equation;

y = -79(3) - 469

y = -237 - 469 = -706
