ABC is similar to DEF. Find x.

<h3>Answer:  25</h3>

Through using the pythagorean theorem, you should find the hypotenuse of the smaller triangle to be 10 units. Therefore, the perimeter of the smaller triangle is 6+8+10 = 24 units.

The perimeter of the larger triangle is 60 units. The ratio here is 24:60 = 2:5

Meaning that the larger perimeter is 5/2 = 2.5 times that of the smaller.

We apply this scale factor 2.5 to the smaller hypotenuse 10 to jump to 2.5*10 = 25, which is the length of the larger hypotenuse.

Adam is 4 years older than Tara. Five years ago the sum of their ages was 48. Use algebraic equations to represent the situation
lord [1]

Answer:

Tara is 27 and Adam is 31.

Step-by-step explanation:

Tara: x years old

Adam: x+4

Subtract the five years to get their current age

x-5 and x+4-5

x-5 and x-1

(x-5) + (x-1) = 48

x-5 + x-1 = 48

2x - 6 = 48

2x= 48+6

2x= 54

x= 27

Tara is 27 and Adam is 31

PLZ HELP WILL GIVE BRAINLIEST TO WHOEVER ANSWERS FIRST What is the slope-intercept form of the equation of the line that passes
grigory [225]

Answer:

A.

Step-by-step explanation:

We are given the two points (2,7) and (4,-1).  In order to determine the linear equation, we need to find the slope and the y-intercept. First, find the slope <em>m.</em> Let (2,7) be x1 and y1, and let (4,-1) be x2 and y2:

m=\frac{y_2-y_1}{x_2-x_1} =\frac{-1-7}{4-2}=-8/2=-4

Thus, the slope is -4.

Now, to find the y-intercept, we can use the point-slope form. Recall that the point slope form is:

y-y_1=m(x-x_1)

Where (x1, y1) is a coordinate pair and m is the slope.

Use either of the two coordinate pair. I'm going to use (2,7). Substitute them for x1 and y1, respectively:

y-(7)=-4(x-(2))\\y-7=-4x+8\\y=-4x+15

This is also slope-intercept form. The answer is A.
