maksim [4K]

2250 = p * 0.06 * 5 -----> 2250 = p * 0.3 (divide it to isolate p) -----> p = 7500

Bx – 10 = f solve for x(z/2) - b = hSolve for z

Free_Kalibri [48]

1) To solve for x, is to let x on the left side and the other terms and variables on the right side.

bx -10=f <em>Add 10 to both sides</em>

bx = f+10 Divide by b on both sides

So that's the way we solve for x.

b) For this one we multiply the whole expression by 2 and then isolate z on the left side, and the rest on the right side.

z = 2h +2b

Please help me solve this problem, and someone please clearly explain to me how to solve it.

allsm [11]

Step-by-step explanation:

For a trinomial ax² + bx + c = 0, the discriminant is b² − 4ac.

If the discriminant is positive, there are 2 real solutions.

If the discriminant is 0, there is 1 real solution.

If the discriminant is negative, there are no real solutions.

a) x² − 4x − 7 = 0

Here, a = 1, b = -4, and c = -7.

b² − 4ac = (-4)² − 4(1)(-7) = 44

The discriminant is positive, so there are 2 real solutions.

b) 4r² + 11r − 3 = 0

Here, a = 4, b = 11, and c = -3.

b² − 4ac = (4)² − 4(11)(-3) = 148

The discriminant is positive, so there are 2 real solutions.

c) 3m² + 7 = 0

Here, a = 3, b = 0, and c = 7.

b² − 4ac = (0)² − 4(3)(7) = -84

The discriminant is negative, so there are no real solutions.

d) t² + 2t + 1 = 0

Here, a = 1, b = 2, and c = 1.

b² − 4ac = (2)² − 4(1)(1) = 0

The discriminant is zero, so there is 1 real solution.

Identify the x-intercept.<br><br> 1) y= 1/5x + 3<br><br> 2) y= 6x - 7<br><br> 3) y= -8/3x + 9

irakobra [83]

1) 1/5x + 3=0

1/5x=-3

x=(-3)(5)=-15

2)6x-7=0

6x=7

x=7/6=1.17

3) -8/3x+9=0

-8/3x=-9

-8x=-27

x=27/8=3.375
