Write the equation of the line that has a slope of 2 and passes through the point (-3,4).
Arte-miy333 [17]

Answer:

y = 2x + 10

Step-by-step explanation:

We are given the slope of the line and the coordinates of one point on the line.  Thus, we use the point-slope formula y - k = m(x - h).  Here m = 2, h = -3 and k = 4.  Therefore we have:

y - 4 = 2(x + 3)

which can be rewritten as y = 2x + 6 + 4, or y = 2x + 10 (Answer D)

A recipe for 8 apple dash cinnamon muffins calls for 1 cup of flour. The number of muffins that can be made varies directly with
Brilliant_brown [7]

Answer:

you can make 14 muffins

Step-by-step explanation:

To get this answer you first need to know that 1 cup makes 8 muffins. Next know that there's 1 3/4 cups of flour. Because you know that 1 cup makes 8 muffins you need to figure out how many muffins 3/4 a cup of flour can make. To do this you divide 8 by 4. Hence 8 divided by 4 is 2. So know you know that for every 1/4 cup you can make 2 muffins. Now since there's 3/4 cup of flour you then multiply 2 by 3 which is 6. Now you have to add 1 cup ( 8 muffins) to 3/4 cup ( 6 muffins ) of flour which then equals 14. You then get the answer , 1 3/4 cups of flour can make 14 muffins. Hope this helped ;)

Factor trinomial x^2n+10x^n+16​
iragen [17]

Answer:

\large\boxed{x^{2n}+10x^n+16=(x^n+2)(x^n+8)}

Step-by-step explanation:

\text{Use}\ (a^n)^m=a^{nm}.\\\\x^{2n}+10x^n+16=(x^n)^2+10x^n+16=x^n\cdot x^n+2x^n+8x^n+16\\\\=x^n(x^n+2)+8(x^n+2)=(x^n+2)(x^n+8)

6. The height of a triangle is 2 units more than the base. The area of the triangle is 10 square units. Find
Harrizon [31]

Answer:

4.24

Step-by-step explanation:

First, let's set up the equation: \frac{2+x^2}{2}=10

Next, clear the fraction by multiplying both sides by 2:2*(\frac{2+x^2}{2}=10)=2+x^2=20

Then, subtract 2 from both sides: x^2=18

Finally, take a square root of both sides and round: \sqrt{x^2=18} =(Rounded to the nearest hundredth) 4.24
