The perimeter of the large triangle = 2 * perimeter of the small one so:-

2x + 4x + 2(4x + 1) = 62

14x = 60

The total cost in dollars for Larry to have his birthday party at a local

luda_lava [24]

Answer:

$0 \leq p < 6$

Step-by-step explanation:

Given

$t = 6.95p + 29.95$

$Amount = 70$

Required

Determine the domain

First, we need to solve for p

Substitute 70 for t in $t = 6.95p + 29.95$

$70 = 6.95p + 29.95$

Collect Like Terms

$6.95p = 70 - 29.95$

$6.95p = 40.05$

Solve for p

$p = 40.05/6.95$

$p = 5.76$

This implies that Larry can not invite up to 6 people.

Hence, the domain can be represented as: $0 \leq p < 6$

briana house is at (1,6) and jordan house is(5,3) what is one possible path from brianna house to jordan house

Maurinko [17]

Answer:

see the explanation

Step-by-step explanation:

Let

A (1,6)------> location Brianna's house on a map

B (5,3)------> location Jordan's house on a map

we know that

One possible path from Brianna's house to Jordan's house it's a straight line ( the shortest distance)

using a graph tool

see the attached figure

Find the distance points AB

the formula to calculate the distance between two points is equal to

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

substitute the values

$d_A_B=\sqrt{(3-6)^{2}+(5-1)^{2}}$

$d_A_B=\sqrt{(-3)^{2}+(4)^{2}}$

$d_A_B=\sqrt{25}$

$d_A_B=5\ units$

The distance from Brianna's house to Jordan's house is 5 units

Add the following rational number = 3/11 and -5/12

tatiyna

Answer:

-19/132

Step-by-step explanation:

To add fractions, find the lowest common multiple of the two denominators and multiply accordingly to make both denominators the same. In this case, the lowest common multiple of 11 and 12 is 132, so we need to multiply the first number by 12 and the second by 11. So we get $\frac{36}{132} + (-\frac{55}{132} )$ = $\frac{36-55}{132}$ = $\frac{-19}{32}$ $-\frac{19}{132}$

Equation of perpendicular line: Equation of parallel line:

tamaranim1 [39]

1)Parallel means they have to have the same slope. Since our equation is y=2/3x+1, a line parallel to that would be(using out points) -5=2/3(-4)+b.

To find the y-intercept, solve for "b".

b=-7/3

Our equation would then be y=2/3x-7/3

2)Perpendicular lines have opposite-reciprocal slopes. our previous equation was y=2/3x+1, so our new equation would be -5=-3/2(-4)+b. Now lets solve for b.

b=-11

So our perpendicular equation would be y=-3/2x-11

Hope that was helpful. :)
