First, we must understand what standard form of a line is. Standard form of a line is written like such that A,B, and C are all integers, and A must be positive. First, we must calculate the slope of the line that passes through theses coordinates.

As a refresher, this is the equation to figure out the slope of two coordinates.Now, we just simplify the numerator and denominator.

The next step is to utilize point-slope form, which is where is a point on the line. Of course, we already know that (7,-3) and (4,-8) both lie of the line. Therefore, plug in one fot he coordinates. Once converted into point-slope, we must then convert into standard form. This is what is demonstrated in the next step.

Let's multiply all sides by 3 to get rid of the fraction early.Distribute the 5 to both terms in the parentheses.Subtract 9 from both sides.Subtract 5x on both sides.We aren't done yet! The coefficient of the x-term must be positive. Therefore, divide by -1 on both sides.This is standard form now, so we are done!

What is the largest number that rounds to 260 when rounding to the nearest ten?

lora16 [44]

Answer:

260 im pretty sure

..........

if there is 5 or higher in the ones place you round up, if there's a 4 or lower you round down. Since there is a 0 in 260 it stays the same so the answer is 260

Drag the tiles to the correct boxes to complete the pairs. Not all tiles will be used.

Answer:

1) shifts f(x) 4 units down = g(x) = $2x-10$

2) stretches by factor 4 = g(x) = $8x-24$

3) shifts f(x) 4 units right = g(x) = $2x-14$

4) compresses by factor 4 = g(x) = $8x-6$

Step-by-step explanation:

1) When we have to move the function down by 4 units, subtract the whole function by -4, that is y -4.

Thus, f(x) becomes g(x) = $2x-6-(4)$ = $2x-10$

2) When the function is stretched away from x axis, it means in Y direction.

Thus, when stretched 4 units in Y direction, the function becomes 4(f(x))

= g(x) = $4(2x-6)$ = $8x-24$

3)When we have to move the function right by 4 units, replace x with (x-4) in the function.

Thus, f(x) becomes g(x) = $2(x-4)-6$ = $2x-8-6$ = $2x-14$

4) When the function is stretched towards y axis, it means in X direction.

Thus, when compressed 4 units in X direction, replace the x by 4x.

= g(x) = $2(4x)-6$ = $8x-6$

Terri and josh Goldman had a pottery stand at the annual craft fair. They sold some of their pottery at the original price of $1

kondor19780726 [428]

Answer:

40 pieces are sold at original price,

45 pieces are sold at reduced price.

Step-by-step explanation:

Let us assume the number of pieces sold at original price = x

Now, the total number of pieces sold = 85

⇒ Number of pieces pieces sold at ( original price + reduced price) = 85

or, The number of pieces sold at reduced price

= 85 - Number of pieces sold at original price = 85 - x

1 piece sold at original price costed = $10.50

⇒ The cost of selling x pieces at original price = x ( Cost of 1 original piece)

= x ($10.50) = 10.50x

Also, 1 piece sold at reduced price costed = $10.50 - $3 = $7.50

⇒ The cost of selling (85 - x) pieces at-reduced price

= (85-x) ( Cost of 1 reduced price piece)

= (85-x) ($7.50) = 7.50 (85-x)

Now, the all pieces are sold at $757.50

⇒ 10.50 x + 7.50 (85-x) = $757.50

or, 10.50 x + 637.5 - 7.5x = 757.5

or, 3 x = 757.5 - 637.5 = 120

or, x = 120/3 = 40

or, x = 40

hence, 40 pieces are sold at original price,

(85 -x) = (85 - 40) = 45 pieces are sold at reduced price.
