Answer:

-5+(-2)

Step-by-step explanation:

-5+(-2)= -5-2 = -7

-5/(-2) = 5/2 = 2.5

-5*(-2) = 5*2 = 10

-5 = -5

So, -5+(-2) is the least.

5. You are making your Halloween costume this year. You have 6 yards of fabric and the pattern says that you need to cut it in t

REY [17]

Answer:

The shorter side piece of fabric = x = 8 feet

The longer side piece of fabrics = (x + 2) = 10 feet

Step-by-step explanation:

Total yards of fabrics = 6 yards

you need to cut it in two pieces where one is two feet longer than the other.

First piece= x feet

Second piece= x+2 feet

Convert 6 yards to feet

6 yards = 18 feet

First piece + second piece = total piece of fabrics

x + (x+2) = 18

x + x + 2 = 18

2x + 2 = 18

2x = 18 - 2

2x = 16

Divide both sides by 2

x = 16 / 2

x = 8 feet

8 feet = 2.66667 yards

x + 2

= 8 + 2

= 10 feet

10 feet = 3.33333 yards

The shorter side piece of fabric = x = 8 feet

The longer side piece of fabrics = (x + 2) = 10 feet

Jack and Jill start driving from the same location. Jack drives 30 miles south while Jill drives west. If Jack and Jill are 78 m

arsen [322]

Answer:

72 mles

Step-by-step explanation:

For better understanding, I'll make use of an attachment.

From the attachment,

O represents the start point

$OB = 30$ --- Jack

$AB = 78$ -- Distance between them

Required

Find OA; Jack's distance

To do this, we make use of Pythagoras theorem

$AB^2 = OA^2 + OB^2$

This gives:

$78^2 = OA^2 + 30^2$

$6084 = OA^2 + 900$

Subtract 900 from both sides

$OA^2= 6084 - 900$

$OA^2= 5184$

Take square roots

$OA = \sqrt{5184}$

$OA = 72$

<em>Hence, Jill drove 72 miles</em>

How do u solve this ?

svetoff [14.1K]

Okay, I will give you the building blocks for solving this equation.

Now something you will need to remember is that a triangle will always add up to 180 degrees.

We can use y as that one unknown side in the triangle.

Knowing this, we can say (9x+16) + (6x+15) + y = 180

Then we can combine like terms like so : 15x+31+y = 180

There are two variables though. So we need more information.

Well, turns out we have the exterior angle of a straight line and the angle measures of a straight line must equal 180. We can now use (19x+3) + y = 180.

With both of these equations, you can now solve and find both of the angles

The answer is -2 (negative two) yards away from the goal line (meaning that the ball is in the end zone or past the goal line).

Which graph represents Y as a function of x?

sattari [20]

Answer:

Step-by-step explanation:

a "function" gives every x value exactly one y value.

A, B and C all have 2 or more y values for an x value.

use e.g. a pen and place it vertically (straight top-down, parallel to the y-axis) on the graphs.

how often does the pen intersect the function curve ?

that is what I am talking about.

if it is more than once, than the x value (the point on the x-axis), where you put your pen, has more than 1 y values.

and that is then not a function.

only D is a function. the pen intersects with the function curve only once, no matter where you put the vertical pen.
