Solve for x in the triangle

Mathematics
1 answer:
Stels [109]3 years ago
5 0

Answer:

x=9

Step-by-step explanation:

Since the sides are the same, the base angles must be the same

8x+2 = 10x-16

Subtract 8x from each side

8x+2-8x =10x-16-8x

2 = 2x-16

Add 16 to each side

2+16 = 2x-16+16

18 =2x

Divide by 2

18/2 =2x/2

9 =x

Answer:

1/3

Step-by-step explanation:

Use the Up/to left or right rule to help you

Find a start point (or the one the gave you (3,2)) and then follow the line to the next point that crosses exactly over where to points cross (where poth x and y would be whole numbers) count how many times the point moved up, then how many time it moved left. Put the first over the second in fraction form and there is your slope.

snow_lady [41]
The additive inverse of 7/2 would be -7/2 (option B) Since its. opposite !

A)is the additive inverse of C) ; C) is the additive inverse of A) (not your answer)

B. is the additive inverse for this problem (7/2) so thats how we found that this is your answer (answer)

D is the same thing for the problem (7/2) (not your answer)

7/2 isnt the additive inverse for 7/2 because they are the SAME not the opposite.

PLEASE HELP!! GIVEN THE FOLLOWING TABLE OF DATA FROM A QUADRATIC EQUATION
antiseptic1488 [7]
The roots: this is when y=0, so in yours there are 2 roots. Just look at the x value when y=0 and that is your roots.

Y intercept- this is when x=0, so just look at the y value below x=0 and that is the y intercept. Note the answer will probably be in the form (0,_)

Vertex=do you see a pattern? Well the vertest would be the highest or lowest point of the quadratic equation. Your vertex would be (5,-9) because just look at x=4 and x=6, bit of the y values are -8 and when you look at x=3 and x=7 they are also the same because this is a quadratic equation.

Max or min: yours is a minimum because (5,-9) is the lowest point. Every value left and right of this are higher up the graph, so this would be a minimum.

*something that will help you see this all more clearly is if you graphed this or put it into Desmos to see the vertex etc.

A full waterbed mattress is 8ft by 2ft by 2ft. The mattress is to be filled with water that weighs 62.4 lb/ft^3. Find the weight
Alex_Xolod [135]

Answer:

1997 lbs

Step-by-step explanation:

First we need to find the volume of the mattress

V = l*w*h

V = 8*2*2

V =32 ft^3

Then multiply by the density

32 ft^3 * 62.4 lb / ft^3 =

1996.8 lbs

To the nearest lb

1997 lbs
