Write the equation of a line with the slope of 2, which contains the point
Crazy boy [7]

Answer:

y=2x-16

Step-by-step explanation:

So since we have a point and the slope, we can use the point-slope equation to find our equation of a line

y - y₁ = m(x - x₁)

Here our (x₁, y₁) point is (4, -8) and our m is 2

Plugging in these values to our equation gives us:

y - (-8) = 2(x - (4)) → distributing the negative to the -8 gives y + 8 = 2(x - 4) → distributing the 2 to the (x - 4) gives y + 8 = 2x - 8 → and finally subtracting the  8 from both sides gives our equation of a line y = 2x - 16

29. Write iſ as an improper fraction, and multiply the
Alex Ar [27]

Answer: 29 = 5/6

Step-by-step explanation:

first you would convert 1 2/3 into a improper faction. So you would multiply 1 and 3  then add 2 so 5/3 then multiply that by 1/2. You would multiply the numerators and denominators, so 5 times 1 and 3 times 2 which gives you 5/6.

EXPERTS/ACe/GENIUSES <br> Ill mark as brainlist if correct
katrin2010 [14]
It's probably the first one: "People responded to Earth Day with letters..."
Since it's more of a detail that supports a fact, it's not as important as the other three.

The length of a rectangle is 4 feet longer than twice the width of the same rectangle. if the perimiter of the rectangle is 68 f
Pepsi [2]

Length (L): 2w + 4

width (w): w

Perimeter (P) = 2L + 2w

               68 = 2(2w + 4) + 2(w)

               68 = 4w + 8 + 2w

               68 = 6w + 8

               60 = 6w

               10 = w

Length (L): 2w + 4   = 2(10) + 4   = 20 + 4   = 24

Answer: width = 10 feet, length = 24 feet

Factor the quadratic expression 9x^2+33x+30
kicyunya [14]
Multiply the values of a and c together;

9*30= 270 <— find prime factors of this

270= 3*3*3*5*2

Now find a way to add these factors in different ways to give 33 (b value)

We can try (3*3*2)+(3*5)=?

18+15=33

Now that you know the numbers, break down the b value.

9x^2+18x+15x+30
9x(x+2)+15(x+2) <— make sure the brackets are the same
(9x+15)(x+2) <— check if this expands to the initial answer

Hope I helped :)
