How many solutions are there for this equation? Why?​

Answer:

Step-by-step explanation:

ZTU = 75, since RTS and ZTU are vertical angles, and RTS = 75.

TZU = 43, since TZU and QZX are vertical angles, and QZX = 43.

ZUT = 180 - ZTU - TZU = 180 - 75 - 43 = 62, since triangle ZUT is shown in the diagram, and the sum of its interior angles = 180.

YUW = 180 - 79 - 62 = 39, since TUW is a straight angle, which measures 180 degrees, and angle TUW is the sum of angle ZUY and angle ZUT and angle YUW, by the diagram.

YVU = 180 - ZUY - YUW = 180 - 68 - 39 = 73, since triangle YUV is shown in the diagram, and the sum of its interior angles = 180.

YVW = 180 - YVU = 180 - 73 = 107, since YVW and YVU are supplementary.

Answer:

Step 2: Commutative Property

Step 3: Associative Property

Step-by-step explanation:

According to the Commutative Property of Addition: Two real numbers can be added in either order.

a + b = b + a

Therefore, she used the Commutative Property in Step 2.

In Step 3, she used the Associative Property, in which the grouping of the addends does not change the sum.

Answer:

Slope = 3/5

Step-by-step explanation:

Slope = (change in y) / (change in x)

          = (4 - 10)/(-4 -6)

          = -6/-10

          =  3/5

Answer:

$16

Step-by-step explanation:

1. Simplify 12/45 which is now 4/15. Now we know $4 is made every 15 minutes.

2. Divide into 60(minutes) by the the 15. So 60÷15=4. Now we the number of times 15 can be divided into 60.

3. Multiply the ratio 4/15 by 4/4 to see how much is made in an hour. 4x4/15×4=16/60.

$16 is made in 60 minutes (1 hour).

Graphs are created from functions and equations.

See attachment for the graph of [tex]\mathbf{y = -2x - 4}[/tex]

The equation is given as:

[tex]\mathbf{y = -2x - 4}[/tex]

When x = -2, we have:

[tex]\mathbf{y = -2(-2) - 4 = 0}[/tex]

When x = -1, we have:

[tex]\mathbf{y = -2(-1) - 4 = -2}[/tex]

When x = 0, we have:

[tex]\mathbf{y = -2(0) - 4 = -4}[/tex]

When x = 1, we have:

[tex]\mathbf{y = -2(1) - 4 = -6}[/tex]

When x = 2, we have:

[tex]\mathbf{y = -2(2) - 4 = -8}[/tex]

So, the points on the graph are:

[tex]\mathbf{(x,y) = (-2,0)(-1,-2)(0,-4)(1,-6)(2,-8)}[/tex]

Answer:

-3/2

Step-by-step explanation:

choose an x variable with it's corresponding y variable from the table.

for example -4, 19

then choose another one,

for example 0, 13

-4 will be the x1 and 19 will be y1 (-4=x1) (19=y1)

the second pair,

0 will be x2 and 13 will be y2 (0=x2) (13=y2)

then you need to subtract y1 from y2:       13 - 19 = (-6)

then you need to subtract x1 from x2:       0 - (-4) = 4

now you have y = (-6)

and x = 4

and since rise over run, aka y = rise, x = run, you put y over x. (divide)

y/x   -6/4  simplify = -3/2

Answer:

Rick gets $30 and Tom gets $45.

Step-by-step explanation:

If Rick gets 2 parts, and Tom gets 3 parts, then there are 5 parts. If $75 is split into 5 parts, each part will be worth $15.

Hence,

Rick gets 2 * $15 = $30

Tom gets 3 * $15 = $45

Step-by-step explanation:

[tex]2x - 10 + 4x + 16 = 180 \\ \\ 4x - 2x + 16 + 10 = 180 \\ \\ 2x = 180 - 26 \\ \\ 2x = 154 \\ \\ x = \frac{154}{2} \\ \\ x = 77[/tex]

Answer:

From the above attachment we can conclude that,

[tex](2x - 10)° + (4x + 16)° = 180° \\ 2x - 10 + 4x + 16 = 180 \\ 2x + 4x - 10 + 16 = 180 \\ 6x + 6 = 180 \\ 6x = 180 - 6 \\ 6x = 174 \\x = \frac{174}{6} \\ \boxed{x = 29}[/tex]

Therefore, the value of x is 29

Answer:

21.15 ft

Step-by-step explanation:

18.7 - 14.3 = 4.4 = pool depth

25.55-4.4 = 21.15 = slide height

Answer:

The height of the tallest water slide is 58.55 feet.

Step-by-step explanation:

To find the height of the tallest waterslide, we need to add the height from the surface of the pool to the point where Dominic reached before going down the water slide and the height of the water slide itself.

Dominic jumped from a height of 14.3 feet above the surface of the pool and traveled 18.7 feet straight down into the water, so his total distance from the surface of the pool to the point where he started going up the water slide is:

14.3 feet + 18.7 feet = 33 feet

From there, he traveled up 25.55 feet to the top of the water slide, so the height of the tallest water slide is:

33 feet + 25.55 feet = 58.55 feet

Therefore, the height of the tallest water slide is 58.55 feet.
