Answer:

7

Step-by-step explanation:

|7|

The bars on the outside means absolute value

It means calculate what is on the inside and then take the positive value

The positive value of 7 is 7

If we had | 3-7|  We would find 3-7 = -4  then take the positive value = 4

VashaNatasha [74]
$1,800 (10%) = $180 
jay pays 10% of the expenses beyond the deductible so you multiply the amount beyond the deductible by 10%.
$1,800 - $180 = $1,620 
or
$1,800 (90%) = $1,620
you subtract what jay pays from the total or you multiply the total by 90%

jay pays $180 of the expenses past the deductible (not including his $200 deductible) and his insurance company pays $1,620.

PLEASE NEED HELP NOW!!!!!!!❤️
alexira [117]

Answer:

A. 2564 cm^2

Step-by-step explanation:

There are two triangles (Which both are the same) and three different rectangles.

1. Let's solve the area of the triangles first!

Formula: bh(1/2)

10(26)(1/2)

130

2. Now, let's multiply by 2 since there's two of them:

130(2) = 260

3. So, we got 260. Let's find the area of the three rectangles!

Formula: bh

Rectangle A: 28(36) = 1008

Rectangle B: 10(36) = 360

Rectangle C: 26(36) = 936

4. Add the area of the triangles and the rectangles!

260 + 1008 + 360 + 936 = 2564

So the surface area is 2564 cm^2

Hope this helps! <3

Se sabe q la suma de tres numeros es de 850. El primer es un tercio del segundo y el tercer número es el doble del segundo.¿Cual
murzikaleks [220]

Answer:

Primer número = x = 85

Segundo número = y = 255

Tercer número = z = 510

Step-by-step explanation:

Se sabe que la suma de tres números es 850. El primero es un tercio del segundo y el tercer número es el doble del segundo.

Representamos:

Primer número = x

Segundo número = y

Tercer número = z

Se sabe que la suma de tres números es 850.

x + y + z = 850 ...... Ecuación 1

El primero es un tercio del segundo

x = 1/3 años

El tercer número es el doble del segundo.

z = 2 años

Sustituimos 1 / 3y por x y 2y por z en la Ecuación 1

1 / 3y + y + 2y = 850

y / 3 + 3y = 850

Multiplica ambos lados por 3

y + 9y = 850 × 3

10 años = 2550

y = 2550/10

y = 255

Resolviendo para x

x = 1/3 años

x = 1/3 × 255

x = 85

z = 2 años

z = 2 × 255

z = 510

Por eso,

Primer número = x = 85

Segundo número = y = 255

Tercer número = z = 510

Question 1: Option B: y=\frac{1}{3}x -2

Question 2: Option D: y+1=3 (x+1)

Solution:

Question 1:

The point on the given line are (2, 4) and (4, –2).

Slope of the given line:

$m=\frac{y_2-y_1}{x_2-x_1}

$m=\frac{-2-4}{4-2}

m = –3.

Slope of perpendicular line = –1 ÷ Slope of the given line

Slope of perpendicular line = \frac{1}{3}

Perpendicular line passing through the point (3, 1).

Slope -intercept form using point slope formula,

y-y_1=m(x-x_1)

y-1=\frac{1}{3} (x-3)

y-1=\frac{1}{3} x-1

y=\frac{1}{3}x -2

Option B is the correct answer.

Question 2:

The point on the given line are (0, –3) and (2, 3).

Slope of the given line:

$m=\frac{3+3}{2-0}

$m=\frac{6}{2}

m = 3.

Slope of parallel lines are equal.

Slope of parallel line =3

parallel lines passing through the point (–1, –1).

Point slope formula:

y-y_1=m(x-x_1)

y+1=3 (x+1)

Option D is the correct answer.
