Which equation has a slope of –52 and a y-intercept of –2?
A. –5x – 2y = –4
B. –5x – 2y = 4
C. 5x + 2y = 4
D. 5x + 2y = –4

Answers

Answer:

I'm sure there might be a typo in the question (AKA the slope is -5/2)

but the answer would be

Step-by-step explanation:

y= mx+ b

where m is the slope, and b is the y intercept

y= -52x -2

..........

5x + 2y = –4

2y= -5x -4

y= - 5/2x -2

[tex]y = - \frac{5}{2} x - 2[/tex]

x = −3y + 17 2x − y = −1

Answers

Answer:

Step-by-step explanation:

wdqwdwq

Answer:

y = 5 and x = 2

Step-by-step explanation:

Since we have x = -3y + 17, we're going to substitute this equation into the x-value in the second equation.

2(-3y + 17) - y = -1

Multiply the 2 with the terms within the parentheses.

-6y + 34 - y = -1

Add the y values.

-7y + 34 = -1

Subtract 34 from both sides.

-7y = 35

Divide each side by -7.

y = 5

Now that we know the value of y, we can substitute 5 for the y-value in the first equation.

x = -3(5) + 17

Multiply.

x = -15 + 17

Add the two terms together.

x = 2

9 blue, 5 green, a 4 pink beads. What is the
probability that, nout looking, Starli will select
a silver bead from tne first bag and a blue bead
from the second bag?

Answers

Answer:

Could be because in the first bag there is 10 silver and 9 blue,and both have very close numbers.

Step-by-step explanation:

Im not 100% sure but both the blue and silver have almost the same amount of beads. so the probability could be 75%-90% posible.

What is the solution to the system of equations? One-fourth x minus one-half y = 8 One-half x + three-fourths y = negative 5 (–8, –12) (–8, 12) (8, 12) (8, –12)

Answers

Answer:

Step-by-step explanation:

x/4-y/2=8, x-2y=32, x=32+2y

x/2+3y/4=-5, 2x+3y=-20, x=(-20-3y)/2

32+2y=(-20-3y)/2

64+4y=-20-3y

7y=-84

y=-12, since x=32+2y

x=32+2(-12), x=32-24=8

So the solution is the point (8, -12)

its (8, -12)
