Step-by-step explanation:

It is the only one that fits the equation 3x-1 reasonably

Answer: 17

Step-by-step explanation:

Multiply AB by two and equal it to 34

2(3x-1)=34

6x-2=34

Add two to both sides

6x=36

Divide by 6 on both sides

x=6

Now apply your 6 value into the AB length

3 times 6 minus 1

3x6-1

Answer: 2.5, 17.5

Step-by-step explanation: I'm kinda confused at what those big blue things with numbers are... but im guessing that's just used to indicate the missing values. So 10/4 = 2.5, meaning the ration is 2.5 pounds per week. So 1 week is 2.5 pounds, and 7 weeks is 2.5*7 = 17.5

Answer:

h=34

Step-by-step explanation:

Answer:

y - 7 = -4(x + 4)

Step-by-step explanation:

You want to find the equation for a line that passes through the point (-4,7) and has a slope of -4.

First of all, remember what the equation of a line is:

y = mx+b

Where:

m is the slope, and

b is the y-intercept

To start, you know what m is; it's just the slope, which you said was -4. So you can right away fill in the equation for a line somewhat to read:

y=-4x+b.

Now, what about b, the y-intercept?

To find b, think about what your (x,y) point means:

(-4,7). When x of the line is -4, y of the line must be 7.

Because you said the line passes through this point, right?

Now, look at our line's equation so far: . b is what we want, the -4 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-4,7).

So, why not plug in for x the number -4 and for y the number 7? This will allow us to solve for b for the particular line that passes through the point you gave!.

(-4,7). y=mx+b or 7=-4 × -4+b, or solving for b: b=7-(-4)(-4). b=-9.

Answer:

y - 7 = -4(x + 4)

Step-by-step explanation:

The point-slope equation is y - k = m(x - h), where (h, k) is the given point and m is the slope of the line.

We substitute -4 for h, 7 for k and -4 for m, obtaining:

y - 7 = -4(x + 4)

thanks for free points

Let the two numbers be x and y

since the ratio the two numbers is 4:3,

we can write,

[tex] \frac{x}{y} = \frac{4}{3} [/tex]

[tex]3x = 4y[/tex]

[tex]x = \frac{4}{3} y[/tex]

If 5 is subtracted from this ratio , the new ratio is 7:3. It can be written as,

[tex] \frac{x - 5}{y - 5} = \frac{7}{3} [/tex]

[tex]3(x - 5) = 7(y - 5)[/tex]

[tex]3x - 15 = 7y - 35[/tex]

[tex]put \: x = \frac{4}{3} y \: in \: \: 3x - 15 = 3y - 35,[/tex]

we get,

[tex]3( \frac{4}{3} y) - 15 = 7y - 35[/tex]

[tex] \frac{12y}{3} - 7y = - 35 + 15[/tex]

[tex] \frac{12y - 21y}{3} = - 20[/tex]

[tex] - 9y = - 60[/tex]

[tex]y = \frac{60}{9} [/tex]

[tex]y = \frac{20}{3} [/tex]

[tex]put \: y = \frac{60}{3 } \: \: \: in \: \: x = \frac{4}{3} y,[/tex]

we get,

[tex]x = \frac{4}{3} \times \frac{20}{3} [/tex]

[tex]x = \frac{80}{9} [/tex]

[tex]hence \: the \: numbers \: are \: \: \frac{60}{3 } \: and \: \: \frac{80}{3} [/tex]

Answer:

A $1.50

Step-by-step explanation:

If 3 pens is $4.50, thats 3.5x = 4.5 and x = 1.5 or $1.50 per pen

If 5 pens is $7.50, that's also $1.50 per pen

Step-by-step explanation:

The answer is m = 2, (0,4).

Answer:

L = 52°

J = 45°

K = 83°

Step-by-step explanation:

J = L - 7

K = 2L - 21

J + K + L = 180°

∴ (L - 7) + (2L - 21) + L = 180

4L - 28 = 180

4L = 208

L = 52°

J = 52 - 7 = 45°

K = 2 x 52 - 21 = 83°

Answer:

-2

Step-by-step explanation:

If you add 22 to both sides, and subtract 3n from both side you get 9n + 18 = 0, which you can see if n = -2 will be correct

Answer:

y=-2/3x+3

Step-by-step explanation:

Linear equations most commonly take place in slope-intercept form:

y=mx+b

Here's what the variables mean:

y=the y-coordinate

m=the slope

x=the x-coordinate

b=the y-intercept (the point on the line that crosses the y-axis)

In a linear equation, y and x are left as y and x when m and b are replaced with numbers.

We can do this by using the formula [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]. We plug in any two given points: [tex](x_1, y_1)[/tex] and [tex](x_2,y_2)[/tex].

Because it's easier to calculate with non-fractional values, we can pick the last two points: (3,1) and (6,-1).

[tex]\frac{y_2-y_1}{x_2-x_1}\\\\\frac{-1-1}{6-3}\\= \frac{-2}{3}[/tex]

Therefore, the slope of the line (m) is equal to -2/3.

So far, our equation looks like this: y=-2/3x+b.

To find the y-intercept, we take our equation y=-2/3x+b, plug in any point and solve for b. Let's use the point (3,1).

[tex]y=-\frac{2}{3}x+b\\1=-\frac{2}{3}(3)+b\\[/tex]

3 cancels out

[tex]1=-2+b\\[/tex]

Add 2 to both sides to isolate b

[tex]1=-2+b\\1+2=-2+b+2\\3=b[/tex]

Therefore, the y-intercept (b) is equal to 3.

Now, our equation looks like this: y=-2/3x+3.

I hope this helps!

Answer:5n^2

Step-by-step explanation:

Answer:

x = - 16 , x = 24

Step-by-step explanation:

Given

f(x) = 0.5| x - 4 | - 3  and f(x) = 7, then equating gives

0.5|x - 4 | - 3 = 7 ( add 3 to both sides )

0.5| x - 4 | = 10 ( divide both sides by 0.5 )

| x - 4 | = 20

The expression inside the absolute value can be positive or negative, that is

x - 4 = 20 or - (x - 4) = 20

solving both

x - 4 = 20 ( add 4 to both sides )

x = 24

or

- (x - 4) = 20

- x + 4 = 20 ( subtract 4 from both sides )

- x = 16 ( multiply both sides by - 1 )

x = - 16

Answer:

$13.68

Step-by-step explanation:

An easy way to find 3/8 of $36.48​ is to find 1/8 first. To do this divide 36.48 by 8. This equals 4.56, then to find 3/8 multiply this by 3. Which equals $13.68. A faster way to do this is also to just multiply 3/8*36.48, which also equals $13.68.
