A line with a slope of -2/5 that passes through the point (-10,8)

Answers

Step-by-step explanation:

[tex]m = - \frac{2}{3} \\ ( - 10 ,\: 8) = (x_1,y_1)[/tex]

[tex]y-y_1=m(x-x_1)[/tex]

Plug in the values into the equation

[tex]y - 8 = - \frac{2}{3} (x - ( - 10)) \\ y - 8 = - \frac{2}{3}( x + 10) \\ [/tex]

[tex]y - 8 = - \frac{2}{3} x - \frac{20}{ 3 } \\ y = - \frac{2}{3} x - \frac{20}{3} + 8 \\ [/tex]

[tex]y = - \frac{2}{3} x + \frac{4}{3} [/tex]

To solve for x-intercept , Arrange the values in

[tex]ax + by + c = 0[/tex]

=

[tex] - \frac{2}{3} x - y + \frac{4}{3} = 0[/tex]

To find x-intercept .let y = 0 in the above equation

[tex] - \frac{2}{3} x - y + \frac{4}{3} = 0 \\ - \frac{2}{3} x - 0 + \frac{4}{3} = 0 \\ [/tex]

[tex] - \frac{2}{3} x + \frac{4}{3} = 0 \\ - \frac{2}{3} x = - \frac{4}{3} [/tex]

y = mx + b    

m = -²/₃ and line pases  through (-10, 8) so:

8 = -²/₃(-10) + b

8 = ²⁰/₃ + b

b = 8 - ²⁰/₃

b = 8 - 6²/₃

b = 1¹/₃

b = ⁴/₃

Slope Intercept Form:

                                   y = -²/₃x + ⁴/₃

x-intercept:

-²/₃x + ⁴/₃ = 0

-²/₃x =- ⁴/₃

x = - ⁴/₃ ÷(-²/₃)

x = 2                  

                                   (2, 0)

3x - 7 = x + 3
A)x = -5
B) x = 2
C) x = 5
D) x = -2


Can someone please help me out ??

Answers

Answer:

C

Step-by-step explanation:

So we have the equation:

[tex]3x-7=x+3[/tex]

Subtract x from both sides. The right cancels:

[tex](3x-7)-x=(x+3)-x\\2x-7=3[/tex]

Add 7 to both sides. The left cancels;

[tex](2x-7)+7=(3)+7\\2x=10[/tex]

Divide both sides by 2:

[tex](2x)/2=(10)/2\\x=5[/tex]

So, our answer is C

Answer:

C) x = 5

Step-by-step explanation:

A) 3(-5) - 7 = (-5) + 3

   -15 - 7 = (-5) + 3

   -23 = (-5) + 3

   -23 = -2 (they do not equal the same so no)

B) 3(2) - 7 = (2) + 3

    6 - 7 = (2) + 3

    -1 = (2) + 3

    -1 = 5 (they do not equal the same so no)

C) 3(5) - 7 = (5) + 3

    15 - 7 = (5) +  3

    8 =  (5) + 3

    8 = 8 (they equal the same so yes)

D) 3(-2) - 7 = (-2) + 3

    -6 - 7 = (-2) + 3

    -13 = (-2) + 3

    -13 = 1 (they do not equal the same so no)

Answers

Answer:

Christopher needs 24 feet of fencing. Your rectangle should be 5x7 feet.

Step-by-step explanation:

Line PO is 5 feet wide, and we know that the side across from it is 5 feet wide. 5+5=10. The longer sides are supposed to be 2 feet longer than the shorter sides, so they have to be 7 feet long. 7+7=14. 10+14=24.

If an arrow is shot upward on Mars with a speed of 56 m/s, its height in meters t seconds later is given by y = 56t − 1.86t^2. Find the average speed over the given time intervals. [1, 2]

Answers

Answer:

50.42m/s

Step-by-step explanation:

Average speed is the change in distance of a body with respect to time. This is expressed as:

[tex]v = \delta y/\delta t\\v = \dfrac{y(t_2)-y(t_1)}{t_2-t_1}[/tex]

Given the function of the height in metres expressed as y = 56t − 1.86t² and time interval [1,2]

t₁ = 1sec and t₂ = 2 secs

y(t₂) = 56t₂ − 1.86t₂²

y(2) = 56(2) − 1.86(2)²

y(2) = 112-7.44

y(2) = 104.56

y(t₁ ) = 56t₁  − 1.86t₁ ²

y(1) = 56(1) − 1.86(1)²

y(1) = 56-1.86

y(1) = 54.14

Substituting the derived value into the formula for finding the average speed:

[tex]v = \dfrac{y(t_2)-y(t_1)}{t_2-t_1}\\\\v = \dfrac{104.56-54.14}{2-1}\\\\v = \dfrac{50.42}{1}\\\\v = 50.42m/s[/tex]

Hence, the average speed over the given time intervals. [1, 2] is 50.42m/s

Answers

Answer:

The answer is

-8(2×5-7×2)

=-8(10-14).

= 32.

Answer is 32

Step 1. Solve inside the parentheses so 2x5= 10 and 7x2=14 then you have -8(10-14)

Step 2. Distribute -8 so -8x10= -80 and -8x14= -112 = -80- -112

Step 3. Subtract totals: -80- -112 = 32 it’s a positive because of the two negatives being subtracted together

Eric has a jar of quarters and dimes. He had 48 coins in the jar. The total value of the coins is $7.35. How many quarters are.in the jar?

Answers

Answer:

17

Step-by-step explanation:

$4.25 - 17 quarters

$3.10 - 31 dimes

Answer:

17 quarters and 31 dimes are in the jar

Step-by-step explanation:

First, you need to set up two equations based on the information given.

First is an equation for the total number of coins:

48 = d + q

d = dimes

q = quarters

Second is an equation for the total amount in the jar and the respective amount per variable (d = .1 , q = .25).

7.35 = .1d + .25q

Using the first equation, you need to solve for one variable. In this case well solve for d, so we can later plug it in to solve for q.

48 = d + q

d =  48 - q

Next, we can plug our formula for d into our second equation, so we only have one variable to solve for, q.

.1(48-q) +.25q = 7.35

4.8 - .1q + .25q = 7.36

4.8 + .15q = 7.35

.15q = 2.55

q = 17

Finally, to solve for d with a number, we can plug q = 17 back into our first formula : 48 = d + q

48 = 17 + d

d = 31

I hope this helps!

Complete Question

You are given the dollar value of a product in 2016 and the rate at which the value of the product is expected to change during the next 5 years. Use this information to write a linear equation that gives the dollar value V of the product in terms of the terms of year t. (Let t=16 represent 2016)

2016 Value     Rate

$2150           $250 increase per year

Answer:

The  equation is  [tex]V(t) = 250 (t) + 4.3[/tex]

Step-by-step explanation:

Generally linear equation is represented mathematically as follows

      [tex]y = mx + c[/tex]

Where  y is the dependent variable which in this case is  dollar value of a product (V(t))

   x is the independent variable which in this case is the time in years(t)

  m is the slope which in this case is the  rate at which the value of the product is expected to change during the next 5 years

So  

        [tex]V(t) = m t + c[/tex]

When  t =  16  years

         [tex]2150 = 250 (16) + c[/tex]

=>       [tex]c = 4.3[/tex]

So the linear equation is  

      [tex]V(t) = 250 (t) + 4.3[/tex]

While simplifying the algebraic expression, you must be very careful about the signs.

Here,

(6x-4) (9x-2)

Multiply 2nd expression by 1st expression,

= 6x ( 9x - 2) -4 ( 9x - 2)

[tex] = (54 {x}^{2} - 12x) - (36x - 8)[/tex]

Opening brackets,

[tex] = 54 {x}^{2} - 12x - 36x + 8[/tex]

Simplifying them we get,

Therefore, the answer is 54x^2 - 48x +8.

Twelve decreased by two times a number is 8. Find the number.

Answers

Answer:2

Step-by-step explanation: 12-8=4 4/2=2

Answer:

x = 2

Step-by-step explanation:

We can make an equation that meets the requirements stated.

Decreased signifies subtraction, so 12 will reduce the value after it. A number can be any letter you'd like, but I'll stick to x. Since 2 is multiplying that number, we can make 2 the coefficient. Finally, set it equal to 8.

12 - 2x = 8 Subtract 12 from both sides of the equation.

-2x = -4 Divide by -2 on both sides of the equation.
