A car moving at a constant speed passed a timing device at t=0. After 7 ​seconds, the car has traveled 567 ft. Write a linear function rule to model the distance in feet d the car has traveled any number of seconds t after passing the timing device.

Question # 7

Given two points

Determining the slope of the line passing through the points (0, 0) and (3, 3)

(x₁, y₁) = (0, 0)

(x₂, y₂) = (3, 3)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

                =  [3 - 0] / [3 - 0]

                = 3 / 3  

                = 1

Thus, the slope of the line = m = 1

Question # 8

Given two points

Determining the slope of the line passing through the points (1, 3) and (5, 5)

(x₁, y₁) = (1, 3)

(x₂, y₂) = (5, 5)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

                =  [5 - 3] / [5 - 1]

                = 2/4  

                = 1/2

Thus, the slope of the line = m = 1/2

Question # 9

Given two points

Determining the slope of the line passing through the points (4, 4) and (5, 3)

(x₁, y₁) = (4, 4)

(x₂, y₂) = (5, 3)

Using the formula

Slope = m =  [y₂ - y₁] /  [x₂ - x₁]

                =  [3 - 4] / [5 - 4]

                = -1 / 1  

                = -1

Thus, the slope of the line = m = -1

Step-by-step explanation:

The area of the circular opening is  201.14 sq.inches.

Area is the space occupied by any given surface in a two dimensional plane.

A circular duct has a diameter of 16 inches

Area of the circular opening is given by

πd²/4

d is the diameter of the circle

= (22/7) * (16)²/4

= 201.14 sq.inches

Therefore the area of the circular opening is  201.14 sq.inches.

Hopes this helps !! Message me if explanation is needed !!!

The equation of the line which passes through (2,4) with a slope of 1/2​ is  [tex]y = \frac{x}{2} +3[/tex].

Y = mx + b is the slope-intercept form of the equation of a straight line. In the equation y = mx + b, m is the slope of the line and b is the intercept. X and y represent the distance of the line from x-axis and y-axis, respectively. The value of b is equal to y when x = 0, and m shows how steep the line is.

Given

Slope m = 1/2

Point (x, y) = (2, 4)

Equation of line which passes through a point (x, y) with a slope of m is

y = mx + b

Substitute the values

⇒ [tex]4=\frac{1}{2}(2)+b[/tex]

⇒ 4 = 1 + b

⇒ b = 4 - 1

⇒ b = 3

Substitute m = 1/2 and b = 3 in equation (1)

[tex]y = \frac{1}{2}(x) +3[/tex]

⇒ [tex]y = \frac{x}{2} +3[/tex]

Hence, the equation of the line which passes through (2,4) with a slope of 1/2​ is  [tex]y = \frac{x}{2} +3[/tex].

Answer:

30m, 24m/s

Step-by-step explanation:

Given the expression for the position of the object expressed as:

S = 6t² + 3t + 7,

At t = 0

S0 = 6(0)²+3(0)+7

S0 = 0+0+7

S(0) = 7m

At t = 2

S2 = 6(2)² + 3(2)+ 7

S2 = 6(4)+6+7

S2 = 24+13

S2 = 37

The displacement = S2-S0 = 37-7= 30m

For the velocity

V = dS/dt = 12t+3

At t = 0

V0 = 12(0)+3

V0 = 3

At t= 2

V2 = 12(2)+3

V2 = 24+3

V2 =27

The velocity will be V2-V0 = 27-3 = 24m/s

Answer:

[tex]9[/tex] right-handed gloves and [tex]3[/tex] left-handed gloves were sold.

Step-by-step explanation:

Given:  In one month, [tex]12[/tex] gloves were sold for a total revenue of [tex]\$561[/tex].

            right-handed gloves cost [tex]\$45[/tex] and left-handed gloves cost [tex]\$52[/tex].

To find: How much of each type of gloves did they sell?

Solution: Let they sell [tex]x[/tex]  right-handed gloves, and [tex]y[/tex] left-handed gloves.

Now, cost of each right-handed gloves [tex]=\$45[/tex]

cost of each left-handed gloves [tex]=\$52[/tex]

Total revenue [tex]=\$561[/tex]

So, we get

[tex]45x+52y=561\:\:\:...(i)[/tex]

Also,  in a month [tex]12[/tex] gloves were sold.

So, we get

[tex]x+y=12\:\:\:...(ii)[/tex]

Now, from [tex](ii)[/tex] we get, [tex]x=12-y[/tex].

Putting [tex]x=12-y[/tex] in equation [tex](i)[/tex], we get

[tex]45(12-y)+52y=561[/tex]

[tex]\implies 540-45y+52y=561[/tex]

[tex]\implies7y=561-540[/tex]

[tex]\implies7y=21[/tex]

[tex]\implies y=\frac{21}{7}[/tex]

[tex]\implies y=3[/tex]

Now, putting [tex]y=3[/tex] in equation [tex](ii)[/tex], we get

[tex]x+3=12[/tex]

[tex]\implies x=12-3[/tex]

[tex]\implies x=9[/tex]

Hence, [tex]9[/tex] right-handed gloves and [tex]3[/tex] left-handed gloves were sold.

x² + 4x + 9

Step-by-step explanation:

This is just adding like terms (Adding x²'s to each other, adding x's to each other, etc.)

3x² - 2x² = x²

-x + 5x = 4x

7 + 2 = 9

So all together its x² + 4x + 9.

Were they both 45? I'm kinda confused on that part, but I think Ralph would be 48 and Bob would be 50

Step-by-step explanation:

Answer:

34 and 17

Step-by-step explanation:

Bob = B

Ralph = R

B=2R

B-3+R-3=45

B+R-6=45

+6         +6

B+R=51

Substitute B for 2R

2R+R=51

3R=51

R=17

2(17)=34

so B is 34 and R is 17

Answer:

a) (X - 4)x 5 = 15

b) the answer is 7

Step-by-step explanation:

divide 15 by 5 and then add 4, do the equasion backwards :)

The solution of the given equation (X - 4)x 5 = 15 would be equal to 7.

An equation is an expression that shows the relationship between two or more numbers and variables.

Now we will try solving it first using the method of substitution in which we express one variable in other variable's form and then you can substitute this value in other equation to get linear equation in one variable.

We are given that a number subtract 4, then divide by 5. The result equals 15.

a) The equation form as

(X - 4)x 5 = 15

b) Now solving the equation as;

(X - 4)x 5 = 15

5x - 20 = 15

x = 35/7

x = 7

Hence, the answer is 7
