Evaluate: p+2c +3f+6t when p= 15, c=7, f = -3, and t= 1.

Answer:

8

Step-by-step explanation:

[tex]2x + 4x = x + 10 \\ 6x - x = 10 \\ 5x = 10 \\ x = 10 \div 5 \\ x = 2 \\ kl = 4x \\ 4 \times 2 = 8 \\ kl = 8[/tex]

If the value of x will be 2. Then the length of KL will be 8 units.

Coordinate geometry is the study of geometry using the points in space. Using this, it is possible to find the distance between the points, the dividing line is m:n ratio, finding the mid-point of the line, etc.

Point K is on line segment JL. Given JL = x + 10, KL = 4x, and JK = 2x.

Then the value of x will be

     JL = JK + KL

x + 10 = 2x + 4x

    5x = 10

      x = 2

Then the length of KL will be

KL = 4x

KL = 4 (2)

KL = 8 units

Answer:

x = -7

Step-by-step explanation:

This is a multi-step equation in algebra. We are expected to isolate the given variable and find the constant value that it is equal to. In order to do this, we can follow some steps:

1x - 15 = 5x + 13 Subtract 5x on both sides of the equation.

-4x - 15 = 13 Add 15 to both sides of the equation.

-4x = 28 Divide by -4 on both sides of the equation.

x = -7

You can input this value and make sure that the answer is correct.

1(-7) - 15 = 5(-7) + 13

-7 - 15 = -35 + 13

-22 = -22

-22 equals -22, so x = -7 is the solution to the equation.

Answer:

x= -7

Step-by-step explanation:

We are given the equation:

1x-15=5x+13

We want to solve for x. Therefore, we must isolate x on one side of the equation.

First, let’s move all the terms with variables to one side. Subtract 1x from both sides.

1x-1x-15=5x-1x+13

-15= (5x-1x)+13

-15=4x+13

Next, move all the constants, or terms without variables to one side. Subtract 13 from both sides.

-15-13=4x+13-13

-15-13=4x

-28=4x

Finally, divide both sides by 4. We should divide because x is being multiplied by 4 and the inverse of multiplication is division.

-28/4=4x/4

-28/4=x

-7=x

Let’s check our solution. Plug -7 in for x and solve.

1x - 15 = 5x + 13

1(-7) - 15 = 5(-7) + 13

-7-15=5(-7)+13

-22= 5(-7)+13

-22= -35+13

-22=-22

This checks out, so we know our solution is correct.

The solution to 1x - 15 = 5x + 13 is x= -7

Equation of a Straight Line

1.1     Solve   y-x-1  = 0

Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).

"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.

In this formula :

y tells us how far up the line goes

x tells us how far along

m is the Slope or Gradient i.e. how steep the line is

b is the Y-intercept i.e. where the line crosses the Y axis

The X and Y intercepts and the Slope are called the line properties. We shall now graph the line  y-x-1  = 0 and calculate its properties

Graph of a Straight Line :

Calculate the Y-Intercept :

Notice that when x = 0 the value of y is 1/1 so this line "cuts" the y axis at y= 1.00000

 y-intercept = 1/1  =  1.00000  

Calculate the X-Intercept :

When y = 0 the value of x is 1/-1 Our line therefore "cuts" the x axis at x=-1.00000

 x-intercept = 1/-1  = -1.00000  

Calculate the Slope :

Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 1.000 and for x=2.000, the value of y is 3.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 3.000 - 1.000 = 2.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)

   Slope     =  2.000/2.000 =  1.000  

Geometric figure: Straight Line

1.  Slope = 2.000/2.000 = 1.000

2. x-intercept = 1/-1 = -1.00000

3.  y-intercept = 1/1 = 1.00000

The equation of the line that passes through the given points will be y=1.5x-4.

A straight line is a combination of endless points joined on both sides of the point.

The slope 'm' of any straight line is given by:

A linear equation has the form y = mx + b in the slope-intercept format. X and Y are the variables in the equation. The values m and b represent the line's slope (m) and the value of y when x is 0.

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

It is given that the line passes through (0,4) and (2,7)

The slope of the line is,

m = (7-4)/(2-0)

m=3/2

m=1.5

The equation of the line passes through the points (0,4) and (2,7) and has a slope of 1.5 will be,

y-4=1.5(x-0)

y-4=1.5x

y=1.5x-4

Thus, the equation of the line that passes through the given points will be y=1.5x-4.

Answer:

B. 1-third

Step-by-step explanation:

The formula for probability = Number of favorable outcomes/ Total number of outcomes

From the question, we are told that:

Owen knows he only has three pencils in his backpack, and they are all yellow. Hence, total number of outcomes = 3

He reaches into his backpack without looking and takes out a pencil.

Hence, total number of favorable outcomes = 1

What is the probability that the pencil was yellow?

Probability ( That the pencil is yellow) =

Number of favorable outcomes/ Total number of outcomes

= 1/3

Therefore, the probability that the pencil was yellow is 1/3 or one - thirds

Answer:

B

Step-by-step explanation:

The range of the function is {0, 3}.

The range of a function on a graph is the set of all possible output values (y-values) that the function can take. To find the range of the given function, we need to determine the y-values corresponding to the points where the function is defined.

Let's analyze the points provided:

The line crosses the x-axis at (-4, 0). This means the function's y-value is 0 when x = -4.

The line turns at (-1, 3). This point is on the line, so the function's y-value is 3 when x = -1.

The line crosses the y-axis at (0, 2). This means the function's y-value is 2 when x = 0.

The line crosses the x-axis again at (2, 0). This means the function's y-value is 0 when x = 2.

Now, let's consider the intervals between these points:

a) When x < -4 (to the left of -4): The function's y-value is 0, as the line is horizontal at y = 0.

b) When -4 ≤ x < -1: The function's y-value starts at 0 and increases to 3, as the line rises from (−4, 0) to (−1, 3).

c) When -1 ≤ x ≤ 2: The function's y-value remains constant at 3, as the line is horizontal at y = 3 between (−1, 3) and (2, 3).

d) When x > 2 (to the right of 2): The function's y-value decreases from 3 to 0, as the line descends from (2, 3) to (2, 0) and further to the right.

So, the range of the function is {0, 3}.

In mathematical notation, the range is written as:

Range = {y | y = 0 or y = 3}

Answer;

m<EAD=29°

m<CAB=119°

Step-by-step explanation:

Angles on a straight line sum up to 180°

This implies that,

61°+90°+EAD=180°

151°+EAD=180°

Subtracting 151° from both sides,we obtain,

EAD=180°-151°

EAD=29°

Angles on a straight line add up to 180°.

this implies that,

CAB+61°=180°

Subtracting 61° from both sides,we obtain

CAB=180°-61°

CAB=119°

Thus,m<EAD=29° and m<CAB=119°

Answer:

29° and 119°

Step-by-step explanation:

Since CF is a straight line, then

90° + ∠ EAD + 61° = 180°, that is

∠ EAD + 151° = 180°  ( subtract 151° from both sides )

∠ EAD = 29°

and

∠ CAB + 61° = 180° ( subtract 61° from both sides )

∠ CAB = 119°
