approximate the number ∛-12 to the nearest a) integer and b) tenth

Answers

Answer 1

Answer:

Below in bold.

Step-by-step explanation:

∛-12

The nearest cube  to -12 is -8    ( -27 is the next after -12)

a) The answer is -2.

b) we can do this by trial and improvement

It must be between -2 and -3, closer to -2 than 3 so first we guess -2.1

(-2.1)^3 = -9.261

(-2.2)^3 = -10.648

(-2.3)^3 = `2.167  - very close

Answer is -2.3 .

Step-by-step explanation:

x + 10 = 45

x = 35

Answer:

x=35

Step-by-step explanation:

Opposite sides are equal so angle MNL is equal to JNK.

THerefore, JNK is 45 degrees.

So, x+10=45. We can simplify this to x=35.

Can anyone help me with this please I really need help with this rq .

Answers

Answer:

Step-by-step explanation:

g(x) = ax - b

-76 = 27a - b

-79 = 28a - b           Subtract

3 = -a                       Multiply both sides by  -1

a = -3

g(x) = -3x - b

-85 = -3*30 - b

-85 = - 90 - b          Add 90 to both sides

90-85 = - b             Combine

5 = - b                     Multiply both sides by - 1

-5 = b

g(x) = -3x - b

g(x) = -3x - (-5)

g(x) = - 3x + 5

Graph ​y+6=45(x+3)​ using the point and slope given in the equation. Use the line tool and select two points on the line.

Answers

Answer:

Step-by-step explanation:

We are given the equation y+6 = 45(x+3).

On simplifying the equation we get,

y+6 = 45x + 45×3

i.e. y+6 = 45x + 135

i.e. y = 45x + 129.

Now, x = 0 gives y = 129 and y = 0 gives x = -2.867.

The general form of a straight line is given by y = mx + c, where m is the slope and c is the y-intercept.

So, on comparing, the slope of given equation is m = 45.

Plotting this straight line y = 45x + 129 on the graph gives the following figure.

The two points selected on the graph are (0,129) and (-2.867,0).

What is the equation of the line in slope-intercept form?

Write your answer using integers, proper fractions, and improper fractions in simplest form.

Answers

Answer:

[tex]y=-\frac{1}{4}x\\[/tex]

Step-by-step explanation:

The slope is calculated by "up ÷ across".

= -1 ÷ 4

= [tex]-\frac{1}{4}[/tex]

The y-intercept is just 0 (because the line meets at the y axis at 0).

So, using [tex]y=mx+b[/tex] (where m = slope and b = y-intercept),

[tex]y=-\frac{1}{4}x+0[/tex]

but the '+0' is unnecessary so we just say [tex]y=-\frac{1}{4}x[/tex]

If 4 gallons of milk cost $16.24, how much would 7 gallon of milk cost

Answers

Answer:

$28.42

Step-by-step explanation:

First let's calculate the cost per gallon.

We can do this by simply dividing the cost of 4 gallons by 4

1 gallon of milk cost 16.24/4 = 4.06

We want to find the cost of 7 gallons.

We can easily do this by multiplying the cost of one gallon by 7

7 gallons of milk cost 7 * 4.06 = $28.42
