Answer:

Step-by-step explanation:

We know that:

We observe the denominator of the first expression is same as the product of the denominators of the second expression.

Compare the numerators and solve for b:

Answer:

[tex]3x - 5 = 7x + 11 \\ 7x - 3x = - 11 - 5 \\ 4x = - 16 \\x = - \frac{16}{4} \\ \color{yellow} \boxed{x =-4}[/tex]

Answer:

x= -4

Step-by-step explanation:

3x-5=7x+11

3x-5+5=7x+11+5

3x=7x+11+5

3x=7x+16

3x-7x=7x+16-7x

-4=7x+16-7x

-4x=16

divided each side by -4

x= 16 over -4

divide them and you get -4.

100 - j = j - 40

100 + 40 = j + j

140 = 2j

140/2 = j

70 = j

Answer:

Step-by-step explanation:

collecting like terms we have:

5x-2x=-1+42

equating the terms..we have:

3x=41

divide both sides by the Co-efficient of x:

3x\3=42\3

x=39.6

Answer:

x = -3

Step-by-step explanation:

Answer:

x=-3

Step-by-step explanation:

You can just do +x on both sides so: 0=3+x and then -3 on both sides: -3=x.

Answer:

After 5 additional shots, the brothers will have a tied score.

Step-by-step explanation:

find equations

henry:

y-int is 15 because that is the starting number. the slope is 3 because that is how much his points are increasing for every successful shot. we can use this information to form this equation:

y = 3x + 15

brother:

y-int is 20 because that is the starting number. slope is 3 because that is how many points he gets for each successful shot. using this information, we can form the following equation:

y = 2x + 20

--

solve

y = 3x + 15

y = 2x + 20

3x + 15 = 2x + 20

x + 15 = 20

x = 5

Answer:

27s

Step-by-step explanation:

d = distance to rendezvous point in miles

t = time of arrival at 10mph, i.e. 3 mins later than appointed time

10 mph = 10 miles per hour = ¹/₆ miles per min

12 mph = ¹/₅ miles per min

t = d/(¹/₆)

t = 6d

5 min = ¹/₁₂ hr

t - ¹/₁₂ = d/(¹/₅)

t = 5d + ¹/₁₂

Elimination of t:

6d = 5d + ¹/₁₂

d = ¹/₁₂ mi

t = 6(¹/₁₂)

t = ¹/₂ min

Time left to appointed time = ¹/₂ - ³/₆₀

= ¹⁰/₂₀ - ¹/₂₀

= ⁹/₂₀.min → 27 seconds

Answer:

27 min

Answer:

25π

Step-by-step explanation:

C= πd

d=√(24²+7²)=√(576+49)=√625=25

C=25π

Answer:

Step-by-step explanation:

First off, divide 24 by 2 as that would give you the radius of the circle

24cm / 2cm = 12cm

Next, use the formula to calculate the circumference of a circle and plug in radius:

C = 2 x π x r

   = 2 x π x 12cm

   = 75.40cm is the circumference

Answer:

-1/6

Step-by-step explanation:

apply fraction rule to get 1/2(-3)

Multiply the numbers to get 1/-6

apply fraction rule to move negative to make

-1/6

1/2 divided by (-3) = -1/6 or -0.1666666667.

Answer:

No. Correct is 7x - 10y = 6.

Step-by-step explanation:

The slope of the line is (-9-5)/(-12-8) = 7/10

y - 5 = 7/10(x - 8)

10y - 50 = 7(x - 8)

10y - 50 = 7x - 56

7x - 10y = -50 + 56

7x - 10y = 6.

Explanation:

Let's plug in x = 8 and y = 5. This is directly from the ordered pair (8,5).

7x - 10y = 3

7*8 - 10*5 = 3

56 - 50 = 3

6 = 3

We get a false equation at the end, which means the original equation is false when (x,y) = (8,5). Therefore, the point (8,5) is not on the line 7x-10y = 3. Furthermore it means that 7x-10y = 3 is not a good model since Devon wanted the line to pass through both given points.

If you were to plug in (x,y) = (-12,-9), then you would find the same thing happens. For each ordered pair, the left side results in 6. So if Devon were to change that "3" to "6", then it would be a good model as both points would be on the line. In other words, the standard form equation Devon should use is 7x-10y = 6. When solving for y, Devon would get y = (-7/10)x - 3/5

Below is visual confirmation that 7x-10y = 3 is not a good model. Both points are not on the line. The graph was made using GeoGebra.

Answer:  The correct answer is (3x+1)(x-4)

Step-by-step explanation:

(3x+1)(x-4)

3x(x-4)            +               1(x-4)

3x^2 - 12x       +                  x-4

3x^2 - (12x + x)-4
