Answer:

  c ≈ 4.69

Step-by-step explanation:

The Law of Cosines is used for the purpose. It tells you ...

  c² = a² +b² -2ab·cos(C)

  c² = 5² +7² -2·5·7·cos(42°) ≈ 21.9799

  c ≈ √21.9799 ≈ 4.688

The measure of side c is about 4.69 units.

Answer:

s - t = 10 - -7 = 17

Step-by-step explanation:

I only see

s - t

nothing else is there to evaluate (or calculate).

s - t = 10 - -7 = 17 (as a double "-" always turns into a "+").

you really needed help with that ?

Answer:

= s-t

= 10 - (-7)

= 10 + 7

= 17

Answer:

[tex]\boxed {\boxed {\sf y= -1.2 }}[/tex]

Step-by-step explanation:

We are asked to solve the following equation for y.

[tex]-2y-4.2= 1.8 + 3y[/tex]

To solve for y, we have to isolate the variable by performing the inverse operations.  First, move all the terms without a variable or the constants to one side, and the terms with a variable to the other side.

4.2 is being subtracted and the inverse operation of subtraction is addition. Add 4.2 to both sides.

[tex]-2y-4.2 +4.2= 1.8 + 3y+ 4.2[/tex]

[tex]-2y=1.8 + 4.2 + 3y[/tex]

[tex]-2y= 6 + 3y[/tex]

3y is being added and the inverse operation of addition is subtraction. Subtract 3y from both sides.

[tex]-2y-3y= 6+ 3y -3y[/tex]

[tex]-2y-3y= 6[/tex]

[tex]-5y=6[/tex]

y is being multiplied by -5. The inverse operation of multiplication is division. Divide both sides by -5.

[tex]\frac {-5y}{-5}= \frac{6}{-5}[/tex]

[tex]y=- 1.2[/tex]

Check the answer by substituting -1.2 back into the original equation.

[tex]-2 (-1.2)-4.2 = 1.8 + 3(-1.2)[/tex]

[tex]2.4-4.2=1.8 + - 3.6[/tex]

[tex]-1.8 = -1.8[/tex]

This checks out, so we know our answer is correct.

Answer:

Answer:

The answer is: y = |x| - 2

Answer:

A. The function is Nonlinear.

Answer:

Yes, both equations are equivalent

Step-by-step explanation:

Simplifying [tex]10x - 3 + 2x - 5[/tex] by combining "like terms" gives us [tex]12x-8[/tex].

Now, to solve "four (3X - 2)", we need to use the distributive property. Doing [tex](4\cdot3x)-(4\cdot2)[/tex] gives us [tex]12x-8[/tex] again.

Therefore, [tex]10x - 3 + 2x - 5[/tex] and four (3X -2) are equivalent!

Answer:

y = - 1/3x

Step-by-step explanation:

So the equation of a line can be written in the form y= mx+ c

Here y is the value of y in the y axis, x is the value of x in the x axis, m is the gradient ad c is the co-efficient.

We need to find the gradient of the line which is - 1/3.

That makes our equation y = - 1/3x

Step-by-step explanation:

area of the base is the area of the rectangle 5×12.

B = 5×12 = 60 in²

the height h is then the side going up from that base rectangle : 4 in.

the perimeter of the base (rectangle) is 2×length + 2×width

P = 2×12 + 2×5 = 24 + 10 = 34 in.

Answer:

D. 13

Step-by-step explanation:

You just have to plug in numbers then solve.

(1,9) and (1,-4). Every coordinate is placed as (x,y)

(1,9) is labeled as (x1, y1)

(1,-4) is labeled as (x2,y2)

Now plug in the numbers.

d= Square root of (1-1)^2 + (-4-9)^2

d= Square root of 1^2 +-13^2

d= Square root of 1+169

d= Square root of 170

d= 13.04

Rounded to a whole number, the answer is 13

Answer:

D

Step-by-step explanation:

you have to substitute the values in the distance formula,in this case x2 is 1,x1 is 1,y2 is -4 and y1 is 9

d=√(x2-x1)²+(y2-y1)²

=√(1-1)²+(-4-9)²

=√(0)²+(-13)²

=√169

=13

I hope this helps

Answer:

D

Step-by-step explanation:

Instead of 2x + 11 = 5x + 16, you should have put 2x+11 = 5x - 16. There is a sign change right before the 16, and you may have accidentally written down +16 instead of -16. I think that's where the problem is.

2x + 11 = 5x - 16

subtract 5x from both sides to make all variables on one side

-3x + 11 = -16

subtract 11 from both sides to isolate the x and its coefficient

-3x = -27

divide both sides by -3 to isolate x

x = 9

Answer:

P = 1,-10

Q=1,-1

R=7,-1

S=7,-10

Step-by-step explanation:

[tex] \frac{ \sin(81) }{x} = \frac{ \sin(40) }{7} \\ x \times \sin(40) = 7 \times \sin(81) \\ x = \frac{7 \times \sin(81) }{ \sin(40) } = 10.75 = 10.8 \: cm[/tex]

Answer:

x is 10.8 cm

Step-by-step explanation:

from Lami's theorem:

[tex] \frac{7}{ \sin(40 \degree) } = \frac{x}{ \sin(81 \degree) } \\ \\ x = \frac{7 \sin(81 \degree) }{ \sin(40 \degree) } \\ \\ x = 10.8 \: cm[/tex]

Answer:

It's A

Step-by-step explanation:

The money earned is 160 in 7 hours

The money earned is 100 in 3 hours

The slope = change in money / change in time

The slope = (160 - 100 ) / (7 - 3) = 60/4 = 15 dollars / hour

The slope means that for every hour he earns 15 dollars.

Answer:

7x = 42

Step-by-step explanation:

"Product" refers to multiplication and "is" refers to equal to.

Hi! I'm happy to help!

This equation will be written like this

x×7=42

To make this easier to solve, we can use the inverse operation, division.

42÷7=x

42 divided by 7 is 6, so the answer is 6.
