A line that includes the point (-10,-5) has a slope of -8. What is its equation in point-slope form?

Answer:

The ages of the four siblings are: 5, 7, 9 and 11 years old.

Step-by-step explanation:

The computation of the age of the four siblings is shown below:

Given that

n = 4

a1 =? a2 =? a3 =? a4 =?

a4 = a1 + 6 years

S4 = 32

Based on the above information

As we know that

Sn = (a1 + a4) ×  n ÷ 2

S4 = (a1 + a4) × 4 ÷ 2

32 = (a1 + a1 +6) × 2

16 = 2a1 + 6

 2a1 = 10

 a1 = 10 ÷ 2

= 5

So,  a4 = a1 +6

= 5 +6

= 11

a4 = a1 + (4-1) × d

11 = 5 + 3 × d

d = 6 ÷ 3

= 2

So,

a2 = a1 + d

= 5 + 2

= 7

a3 = a2 + d

= 7 + 2

= 9

Hence, The ages of the four siblings are: 5, 7, 9 and 11 years old.

:

Rewriting the whole as an Equivalent Fraction

2.1   Subtracting a fraction from a whole

Rewrite the whole as a fraction using  2  as the denominator :

          5t     5t • 2

    5t =  ——  =  ——————

          1        2  

Equivalent fraction : The fraction thus generated looks different but has the same value as the whole

Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator

Adding fractions that have a common denominator :

2.2       Adding up the two equivalent fractions

Add the two equivalent fractions which now have a common denominator

Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

5t • 2 - (7)     10t - 7

————————————  =  ———————

     2              2  

Equation at the end of step

:

 10t - 7

 ———————  = 0

:

When a fraction equals zero :

3.1    When a fraction equals zero ...

Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.

Here's how:

 10t-7

 ————— • 2 = 0 • 2

   2  

Now, on the left hand side, the  2  cancels out the denominator, while, on the right hand side, zero times anything is still zero.

The equation now takes the shape :

  10t-7  = 0

Solving a Single Variable Equation:

3.2      Solve  :    10t-7 = 0

Add  7  to both sides of the equation :

                     10t = 7

Divide both sides of the equation by 10:

                    t = 7/10 = 0.700

One solution was found :

t = 7/10 = 0.700

Answer:

75 degrees

Step-by-step explanation:

3x+15 = 4x - 5

-3x       -3x

15=x-5

+5    +5

x=20

4(20)-5 = 75

Answer:

75

Step-by-step explanation:

1 and 2 are corresponding angles meaning that they are equal to each other or congruent

so we set up an equation

4x-5=3x+15 and since for x

step 1 subtract each side by 3x

4x-3x=x

now we have

x-5=15

step 2 add 5 to each side

5+15=20

x=20

now we just plug in 20 to 4x - 5

4x20=80

80-5=75

therefore your answer is 75

Answer:

earthworm

Step-by-step explanation:

The worm which hasbristles, called setae, on its soft body to help it move is roundworm, the correct option is roundworm.

Worms are described as many different distantly related bilateral animals that typically have a long cylindrical tube-like body, no limbs, and no eyes. Roundworms constitutes of the phylum Nematoda, with plant-parasitic nematodes also known as eelworms.

Given;

The worms has bristles, called setae

Now,

Roundworm infections usually occur when soil, sand, or plants that have been contaminated with infected animal feces are accidentally put in the mouth and ingested by individuals;

Therefore, the worm will be roundworm.

The Range is x>5 or b

Step-by-step explanation:

The domain of the function y = √(x+7) + 5 is [-7, ∞).

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

The given equation is y = √(x+7) + 5.

For the expression under the square root to be non-negative, we must have x + 7 ≥ 0.

The domain of the function is all real numbers greater than or equal to -7.

Thus,

The domain of the function y = √(x+7) + 5 is [-7, ∞).
