Answer:

Easy pie

Step-by-step explanation:

5(x - 3) + 2 = 5(2x - 8) - 3​

5x - 15 + 2 = 10x - 40 - 3

5x - 10x = 15 - 2 - 40 - 3

-5x = -30

5x = 30

x = 6

Answer:

3, 0

Step-by-step explanation:

So, if we rewrite our given equation to have its 0x its easier to picture factorising it.

Factorise into (x+3)(x-3)

Make this equation equal to zero

Solve for your two pairs, -3, 0 (which was given in the question- I wrote this in green)

and 3, 0 (I wrote this in blue)

9514 1404 393

Answer:

  (-3, 0) (given) and (3, 0)

Step-by-step explanation:

Apparently, the "solution" you're looking for is the solution to f(x) = 0.

To find the solutions, look for table values where y = 0. The solutions are the corresponding x-values. The (x, y) pairs that are solutions can be read from the table:

  (-3, 0) and (3, 0)

Step-by-step explanation:

Answer:

9 pints

Step-by-step explanation:

there are two cups in a pint, so we need to divide 16 by 2 to convert the cups to pints.

16 ÷ 2 = 8

9 is greater than 8, so 9 pints.

The distance between the tornado, and both spotters is an illustration of bearing and distance.

See attachment for the positioning of the tornado, and the two spotters.

First, we calculate the angle T.

[tex]\mathbf{\angle T + 43 + 59 = 180}[/tex] ---- Sum of angles in a triangle

[tex]\mathbf{\angle T +102 = 180}[/tex]

Subtract 102 from both sides

[tex]\mathbf{\angle T = 78}[/tex]

From the attached figure:

To calculate y, we make use of the following sine formula

[tex]\mathbf{\frac{y}{sin(59)} = \frac{35}{sin(78)}}[/tex]

Make y the subject

[tex]\mathbf{y = \frac{35}{sin(78)} \times sin(59)}[/tex]

[tex]\mathbf{y = 30.67}[/tex]

To calculate z, we make use of the following sine formula

[tex]\mathbf{\frac{z}{sin(43)} = \frac{35}{sin(78)}}[/tex]

Make z the subject

[tex]\mathbf{z = \frac{35}{sin(78)} \times sin(43)}[/tex]

[tex]\mathbf{z = 24.40}[/tex]

Next, we calculate x, using the following sine trigonometry ratio

[tex]\mathbf{sin(59) = \frac{x}{z}}[/tex]

Make x the subject

[tex]\mathbf{x = z \times sin(59)}[/tex]

Substitute [tex]\mathbf{z = 24.40}[/tex]

[tex]\mathbf{x = 24.40 \times sin(59)}[/tex]

[tex]\mathbf{x = 20.91}[/tex]

Hence, the required distances are 30.67 miles, 24.40 miles and 20.91 miles.

Answer:

The slope is -3/2

The y intercept is (0, -5) :)

Step-by-step explanation:

the slope is whatever is times by x

the y intercept is what’s being subtracted by it

The values of m and b from the equation of the given line are;

m = -3/2 and b = -5

We are given the equation;. y = -(3/2)x - 5

Now, the general form of an equation of a line in slope intercept form is;

y = mx + b

Where;

m is slope

b is y-intercept

Thus, comparing the general form to our given equation, we can see that;

m = -3/2 and b = -5

I assume you're given the binary number, 11111₂. Expanding the digits in base 10, this is the same as

1•2⁴ + 1•2³ + 1•2² + 1•2¹ + 1•2⁰

= 16 + 8 + 4 + 2 + 1

Answer:

[tex]y=\frac{1}{3}x+7.6666[/tex]

Step-by-step explanation:

First we must convert  [tex]3x+y=-7[/tex] into slope-intercept form!

To do this we simply just need to subtract -3x from the 3x on the left and move it to the right side. This would result in: [tex]y = -3x-7[/tex]

Now that we have our slope-intercept form for the equation remember that to find the equation that is perpendicular to the given equation, you need to use the opposite reciprocal of the slope. This would be [tex]\frac{1}{3}[/tex] as that is the reciprocal and opposite of [tex]-\frac{3}{1}[/tex]

Now in order to find the "b" variable of the equation that goes through the ordered pair (1, 8) we need to plug it in to the given equation!

That equation would be: [tex]y=\frac{1}{3}x-7[/tex]

Given that x = 1 and y = 8 we can plug those in like so:

[tex]8=\frac{1}{3}(1)+b[/tex]

(make sure to set the -7 to b as that's what we're solving for)

1 / 3 is 0.3333 (infinitely repeating)

Next we need to subtract 0.3333 from 8, which would be 7.6666 (infinitely repeating) Remember that the variable needs to be "alone"!

Now we have our "b" for the equation! Hence the equation would be:

[tex]y=\frac{1}{3}x+7.6666[/tex]

(you can also use [tex]\frac{23}{3}[/tex] for the b as that is the "exact form" of 1 / 3 but they both work)

Hope this helps! Feel free to ask questions!
