Answer:

Step-by-step explanation:

so many people on brainly ask about these type of slope - intercept problems, makes me pretty sure it's the teachers having a tough time teaching this and not people having a tough time learning it

so slope-intercept formula looks like y = mx + b

where y is the output ( range) m is the slope and b is the offset from zero

sooo, knowing the above, apply the idea of making a line with a bunch of x inputs to get y outputs.. but think a bazillion inputs.. of x... like x 1.1 and x of 1.2 and x of 1.3 and continue like that till you've graphed an entire line. :P

now that you have that concept of making a line, by using the slope-intercept formula , let's figure out what that formula is

we are told the slope is 1

and that it goes thur a point (P1) (-5,-8)

we should also bring out the point-slope formula here to, and I know, the names make it hard to remember them. which is which. Point-slope means you can plug in a single point into it, while slope-intercept means where it hits the y axis, or intercepts it.

formula for the point-slope is

y-y1 = m(x-x1)

where x1 and y1 are from the point P1 in the form of (x1,y1)

plug in our slope and our point to the point-slope formula and work it to the slope-intercept formula like below ( btw, you always do this, use the point-slope to get to the slope-intercept, unless they just give you the slope-intercept)

y-(-8) = (1)(x-(-5))

y+8 = 1(x+5)

y+8 = x+5

y = x+5-8

y = x-3

that's your slope-intercept formula , if it helps you can write in the slope like this

y = (1)x - 3

but as you can see, that does nothing to change it, so

y = x - 3 is good

Luis earns a base salary of $150.00 every week with an additional 14% commission on everything he sells. If Luis sold $6,050.00

max2010maxim [7]

Luis earns a solid $150 and that doesn't change, now you need to calculate 14% of $6,050.
x=150+(0.14x6050)
150+(847)
997
Luis was paid $997.

If a circle has circumference c, what is it’s are in terms of C

Scilla [17]

$\text {Circumference = } 2 \pi r$

$c = 2 \pi r$

$\text {r = } \dfrac{c}{2 \pi }$

$\text {area = } \pi r^2$

Sub r into area:

$\text {area = } \pi ( \dfrac{c}{2 \pi } )^2$

$\text {area = } \dfrac{\pi c^2}{4 \pi^2 }$

$\text {area = } \dfrac{\ c^2}{4 \pi }$

Answer:

1. y ≥ 100

2. y ≤ 300

3. y ≥ 20000

4. 2y ≥ 80

5. 2y ≤ 90

Step-by-step explanation:

Let y be the variable.

1. The discount is not less than 100.

If the discount (i.e y) is not less than 100, it means it is either 100 or greater than 100.

This can be written as:

y ≥ 100

2. The cost of the book is at most 300.

This implies that the cost of the book (i.e y) is either 300 or lesser.

This can be written as:

y ≤ 300

3. His monthly income is at least 20000. This simply means that his monthly income (i.e y) is 20000 or greater than 20000.

This can be written as:

y ≥ 20000

4. Twice the number is at least 80.

Let the number be y.

Twice the number y can be written as:

But twice the number is at least 80.

This means that twice the number is 80 or greater than 80. This can be written as:

2y ≥ 80

5. Twice the measure of the acute angle is not more than 90 degree.

Let the angle be y.

Twice the angle can be written as:

But twice the measure of the angle is not more than 90 degree. This implies that twice the angle is 90 or lesser than 90. This can be written as:

2y ≤ 90
