Answers

Answer:

x=3.33333333

Step-by-step explanation:

Answer:

x = 10/3

Step-by-step explanation:

Divide the coefficient of x (3) on both sides, 3x/3 = 10/3 - then divide the three and the three to get 1 (which stays as x) and then divide ten by three or just leave it as an improper fraction (this all depends on what your teacher's preference) and then you will get the final answer of x = 10/3 or x = 3.3.

What is an equation of a line?

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

Slope = (d - b) / (c - a)

Where (a, b) and (c, d) are the two points.

Now,

The slope between (-10, -12) and (-8, -8) is 2.

The slope between (-8, -8) and (-6, -4) is 2.

The slope between (-6, -4) and (-4, 0) is 2.

Therefore,

The slope of the line passing through these points is 2.

The slope between (-4, 2) and (0, 1) is -1/4.

The slope between (0, 1) and (4, 0) is -1/4.

The slope between (4, 0) and (8, -1) is -1/4.

Therefore,

The slope of the line passing through these points is -1/4.

The slope between (-7, -7) and (0, -8) is -1/7.

The slope between (0, -8) and (7, -9) is -1/7.

The slope between (7, -9) and (14, -10) is -1/7.

Therefore,

The slope of the line passing through these points is -1/7.

The slope between (-2, 2) and (0, 3) is 1/2.

The slope between (0, 3) and (2, 4) is 1/2.

The slope between (2, 4) and (4, 5) is 1/2.

Therefore,

The slope of the line passing through these points is 1/2.

The slope between (2, -11) and (4, -25) is -7.

The slope between (4, -25) and (6, -39) is -7.

The slope between (6, -39) and (8, -53) is -7.

Therefore,

The slope of the line passing through these points is -7.

The slope between (-11, -38) and (-5, -14) is 6.

The slope between (-5, -14) and (1, 10) is 8.

The slope between (1, 10) and (7, 34) is 6.

Therefore,

The slope of the line passing through these points is 6.

Now,

The equation in slope intercept form is y = mx + c

where m is the slope of the line and c is the y-intercept.

So,

The slope of y = -4x + 6 is -4 and the y-intercept is 6.

The equation y = -1 represents a horizontal line, so the slope is 0 and the y-intercept is -1.

To find the slope-intercept form, we can rewrite 4r + y = -1 as y = -4r - 1.

Therefore,

The slope is -4 and the y-intercept is -1.

The slope of y = 6x - 4 is 6 and the y-intercept is -4.

To find the slope-intercept form, we can rewrite -x - 4y + 8 = 0 as -4y = x - 8, then divide both sides by -4 to get y = (-1/4)x + 2.

Therefore,

The slope is -1/4 and the y-intercept is 2.

To find the slope-intercept form, we can rewrite 2r - 12y + 10 = 0 as 12y = 2r + 10, then divide both sides by 12 to get y = (1/6)r + 5/6.

Therefore,

The slope is 1/6 and the y-intercept is 5/6.

Thus,

The slope and the y-intercept are given above.

answer is (x+16)(x-3) I'm sure

Answer:[tex]\boxed{\boxed{\sf{(x-3)(x+16)~or~(x+16)(x-3)}}}[/tex]Solution Steps:

______________________________

1.) Factor the expression by grouping:

 - First, the expression needs to be rewritten as [tex]x^2+ax+bx-48[/tex]. To find a and b, set up a system to be solved:

[tex]a+b=13[/tex][tex]ab=1(-48)=-48[/tex]

2.) List all such integer pairs that give product −48:[tex]-1,48[/tex][tex]-2,24[/tex][tex]-3,16[/tex][tex]-4,12[/tex][tex]-6,8[/tex]

3.) Calculate the sum for each pair:[tex]-1+48=47[/tex][tex]-2+24=22[/tex][tex]-3+16=13[/tex][tex]-4+12=8[/tex][tex]-6+8=2[/tex]

4.) The solution is the pair that gives sum 13:[tex]a=-3[/tex][tex]b=16[/tex]5.) Rewrite [tex]\bold{x^2+13x-48}[/tex]:[tex]x^2+13x-48=(x^2-3x)+(16x-48)[/tex]

6.) Factor out [tex]\bold{(x)}[/tex] in the first and 16 in the second group:[tex]x(x-3)+16(x-3)[/tex]

7.) Factor out common term [tex]\bold{x-3}[/tex] by using distributive property:[tex](x-3)(x+16)[/tex]

So your answer is [tex]\bold{(x-3)(x+16)}[/tex] or [tex]\bold{(x+16)(x-3)}[/tex].

Step-by-step explanation:

35÷0.20 and you'll get 175

If cell phone plan costs $0.20 cents per minute. Lisa has budgeted $35 a month for her cell phone then 175 minutes  Lisa can use each month

What is Ratio?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.

Given that A cell phone plan costs $0.20 cents per minute.

Lisa has budgeted $35 a month for her cell phone.

We need to find  how many minutes Lisa can use each month.

Let us form a proportional equation to find this.

Let x be the number of minutes Lisa can use each month.

0.20/1=35/x

Apply cross multiplication

x=35/0.2

x=175

Hence, 175 minutes Lisa can use each month.

You decide to buy a custom frame for a painting which measures 4 by 6 inches. If the framing material costs $2 per inch, what is the total cost of framing material?

Answers

Answer:

6 x 4 = 24 x $2 = $48

Step-by-step explanation:

The total cost of the rectangular frame is C = $240.

What is rectangle?

A rectangle is a two-dimensional shape in which the opposite sides are parallel and equal to each other and all four angles are right angles.

Given that, a painting measures 4 by 6 inches, the framing material costs $2 per inch,

We need to find the total cost of framing material

The perimeter is given by:

P = 2x(L + W)

In this case, we know that the frame is 6 inches by 14 inches, then the perimeter will be:

P = 2x(6in + 14in)

P = 2x20in = 40in

Since, the framing material costs $6 per inch, then the total cost of the frame will be:

cost = 40x$6 = $240
