W/6 + 5/8 = -1 3/8 Solve the equation
kozerog [31]

Answer:

w = -12

Step-by-step explanation:

w/6 + 5/8 = -1 3/8

Subtract 5/8 from each side

w/6 + 5/8-5/8 = -1 3/8 - 5/8

w/6 = -1 3/5 - 5/8

w/6 = -1 8/8

w/6 = -2

Multiply by 6 on each side

w/6 *6 = -2*6

w = -12

What is the solution to the equation -3(h+5)+2=4(h+6)-g
dexar [7]

Answer:

h=-4\frac{2}{7}

Step-by-step explanation:

The given equation is

-3(h+5)+2=4(h+6)-9

We expand to obtain;

-3h-15+2=4h+24-9

Group similar terms;

-3h-4h=24-9+15

Combine the similar terms;

-7h=30

Divide both sides by -7

h=-\frac{30}{7}

h=-4\frac{2}{7}

similar ration number can be given as -

<h3>What is rational number?</h3>

Rational numbers are the numbers that can be structured in the form of the fraction of integers. Eg- 5/6, 2/3 etc.

From the option, by above definition 2/3, 0.66(line over 66)7 seems to be an equivalent rational numbers because
6/9=2/3= 0.66(line over 66)7.

Thus, Rational numbers 2/3, 0.66(line over 66)7 are equivalent to 6/9.

Please state the function for the corresponding data set
Lana71 [14]
Given:
x: [1      2         3        4      5    6        7]
y: [9  9.5  10.25  11.25  12.5  14  15.75]

Let the function which models the data be
y(x) = ax² + bx + c

Apply the function to the first three data points
  a +   b + c = 9           .(1)
4a + 2b + c = 9.5        (2)
9a + 3b + c = 10.25    (3)

Subtract (1) from (2).
3a + b = 0.5
or
b = 0.5 - 3a               (4)
Subtract (1) from (3).
8a + 2b = 1.25          (5)
Substitute (4) into (5).
8a + 2(0.5 - 3a) = 1.25
2a = 0.25
a  = 0.125
From (4),
b = 0.5-3*0.125 = 0.125
From (1),
c = 9 - 0.125 - 0.125 = 8.75

The function is
y = 8.75 + 0.125x + 0.125x²

Check that the function works for x=4,5,6,7.
From the calculator, obtain
y(4) = 11.25  Correct
y(5) = 12.5  Correct
y(6) = 14      Correct
y(7) = 15.75 Correct

The graph of the function is shown below.

Answer:  y = 8.75 + 0.125x + 0.125x²
