Y equals 8<br> X equals 575<br><br> Solve for slope intercept <br><br> y equals mx + b
zhannawk [14.2K]

y = 8

x = 575

We want to solve for b in the slope-intercept form y = mx + b.

To complete this problem, we need the value of m, the slope. If you know m, then just plug into y = mx + b this way:

8 = 575m + b

Please need the answer ASAP for number 3!!!!
Radda [10]

Answer:

second and fourth option

Step-by-step explanation:

the <em>discriminant </em>of a quadratic equation is the easiest way to know how many solutions there will be

(discriminant: b²- 4ac)

{a discriminant of 0 means 1 solution; discriminant < 0 means no real roots, discriminant > 0 means two real roots }

so, we can quickly run b² - 4ac for each equation provided:

(note: ax² + bx + c is the formatting we use to find a, b, and c)

8² - 4(-9)(-8)

64 - 288 = -224

4² - (4)(1)(4)

16 - 16 = 0

-1² - (4)(-10)(-9)

-1 - 360 = -361

-6² - (4)(3)(3)

36 - 36 = 0

So, because the second and fourth options listed have a discriminant of 0, they have 1 real solution

hope this helps!! have a lovely day :)

Need help finding out what 3x=y and x-2y = 10
sweet-ann [11.9K]

Answer:

x=-2, y=-6

Step-by-step explanation:

Simple substitution.

Since y is isolated in one of the equations already, you can plug it into the second equation.

x - 2(3x) = 10

x - 6x = 10

-5x = 10

x = -2

Sub. x = -2 into 3x = y:

3(-2) = y

y = -6

Jessica has two salary options. She can earn a salary of $500 per week plus 2% of the weekly sales or a salary of $200 per week
Yuki888 [10]

Answer:

$500 + 0.02x = $200 + 0.05x  

Step-by-step explanation:

Jessica's first option:  J1 = $500 plus sales commission of 2%:

                                     J1 = $500 + 0.02x, where x:  weekly sales amount

Her second option:  J2 = $200 + 0.05x

Equating these two expressions, we get:

$500 + 0.02x = $200 + 0.05x  

... which is the same as the third answer choice.
