Answer:

G is 3 and -1 H is -0 and -4

Step-by-step explanation:

after the 90 degree turn you have G as -3 and -1 and H stays the same

If R is the set of all integers, choose the set S that will make the following statement false.

olga55 [171]

Answer: 1 S = {−2, −1, 0, 1, 2}

Step-by-step explanation:

Integers are whole numbers that could be positive or negative .

This means that

R = { ... -3 ,-2 , -1 , 0 , 1 , 2 , 3 , 4 , ...}

S ⊆ R means that all elements of S is also an element in R , therefore :

S = { -2, -1 ,0, 1 , 2 ...}

A trapezoid has an area of 342 square yards. The length of one base is 17 yards, and the length of the other base is 21 yards. W

dedylja [7]

The height of trapezoid is 18 yards

Solution:

Given that, trapezoid has an area of 342 square yards

The length of one base is 17 yards, and the length of the other base is 21 yards

To find: height of trapezoid

The area of trapezoid is given by formula:

$area = \frac{a+b}{2} \times h$

Where "h" is the height

"a" and "b" are the length of base

Here given that,

area = 342 square yards

a = 17 yards

b = 21 yards

h = ?

Substituting the values we get,

$342 = \frac{17+21}{2} \times h\\\\342 \times 2 = 38 \times h\\\\ 684 = 38h\\\\h = \frac{684}{38}\\\\h = 18$

Thus height of trapezoid is 18 yards

Find the slope and y intercept of the line 14x + 4y = 24

slavikrds [6]

In order to answer this question, I'll have to get that equation
in standard form ===> y = mx + b .

14x + 4y = 24

Subtract 14x from each side: 4y = -14x + 24

Divide each side by 4 : y = -3.5x + 6

There's the standard form we need ==> y = -3.5x + 6

That -3.5 is our slope.
That 6 is our y-intercept.
