Answer:

y - 4= -10(x - 1)

Step-by-step explanation:

Answer:

y-4=-10(x-1)

Step-by-step explanation:

Point-slope form is:

$y-y_1=m(x-x_1)\\m-slope\\(x_1,y_1)-point$

We are given the slope of -10 and the point (1,4). So:

m = -10

x1 = 1

y1= 4

Replace the appropriate values:

$y-4=-10(x-1)$

So, y-4=-10(x-1) should be the point-slope equation.

find the perimeter of an isosceles triangle with side lengths of 5+x, 5+x, and xy. Write in simplest form.

Zinaida [17]

<h3>Answer: perimeter = 10+2x+xy</h3>

To get the perimeter, you add up all the outer sides

side1+side2+side3 = (5+x)+(5+x)+(xy) = 10+2x+xy

The like terms 5 and 5 add to 10. The other pair of like terms x and x add to 2x. There isn't anything to pair with xy, so we leave it as is.

Alex has 128 photos of his friend to display equally in 4 photo albums. Which equation can you use to find how many will be in e

Trava [24]

Answer:

128 ÷ 4 = $\frac{128}{4}=32$

Step-by-step explanation:

Total number of photos = 128

Number of photo albums = 4

Alex has 128 photos of his friend to display equally in 4 photo albums.

Equation that can be used to find number of photos in each album =

Number of photo albums ÷ Total number of photos

= 128 ÷ 4

= $\frac{128}{4}=32$

Lin notices that the number of cups of red paint is always 15 of the total number of cups (0.2 of the total number of cups). She

ivann1987 [24]

Step-by-step explanation:

The number of cups of red paint is always 15 of the total number of cups. 0.2 of the total number of cups.

She writes the equation r = 15t (r = 0.2t) to describe the relationship.

In this case, the total no. of cups is an independent variable. No. of cups do not depend on any term.

The number of cups of red paint is a dependent variable as it depends on the number of cups.

I was doing my homework and got confused on this question.

We will determine the length of the segment DF as follows:

*We have that the triangles are similar, and therefore the following is true:

$\frac{2}{1.34}=\frac{4}{DF}$

Now, we solve for DF:

$\Rightarrow DF=\frac{1.34\cdot4}{2}\Rightarrow DF=2.68$

From this, we have that the length of the segment DF equals 2.68 units.
