x+5≤−4 solve for x

(uh bananas)

Explanation:

The gradient is the same as the slope

m = slope

m = rise/run

m = (change in y)/(change in x)

m = (y2-y1)/(x2-x1)

m = (6-1)/(6 - (-4))

m = (6-1)/(6+4)

m = 5/10

m = 1/2

In decimal form, this becomes 0.5

A slope of 1/2 means we move up 1 and to the right 2 units each time to generate points along the diagonal line.

A positive slope goes uphill as we move to the right (due to the positive rise value).

Answer:

One way to find the gradient is using the expression :

[tex]m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}} = \frac{y_{B} - y_{A}}{x_{B} - x_{A}}[/tex]

So [tex]m = \frac{6 - 1}{6- (-4)} =\frac{5}{10} =\frac{1}{2}[/tex]

Answer:

D

Step-by-step explanation:

The sides of a rhombus are congruent , then

13b - 9 = 3b + 4 ( subtract 3b from both sides )

10b - 9 = 4 ( add 9 to both sides )

10b = 13 ( divide both sides by 10 )

b = 1.3

The diagonals are perpendicular bisectors of each other , then

14a + 20 = 90 ( subtract 20 from both sides )

14a = 70 ( divide both sides by 14 )

a = 5

Thus c = a + b = 5 + 1.3 = 6.3 → D

x = 4.59

Step-by-step explanation:

Since this is a right triangle, we can use trig functions

x = 16/ tan 74

x=4.58792

Answer:

Hexagons, Cross sections parallel to the base will be hexagons. It is also possible to take cross sections using planes that are neither parallel not perpendicular to the base

Answer:

The cross-section parallel to the base is a hexagon congruent to the hexagonal bases. The cross-section perpendicular to the base is a rectangle. The cross-section parallel to the base is a pentagon similar to the pentagonal base. The solid is a cylinder.

Answer:

m=5/3

Step-by-step explanation:

Answer:

5/3 or 1 2/3

Step-by-step explanation:

First you subtract 4/3 from the left side. 23/6-4/3= 2 1/2

Then you multiply 2 on both sides, this simplifies the left side to be 3m and the right side 5.

Lastly, you divide by 3 to isolate the variable m.

And you get 5/3, which also equals 1 2/3

Answer:

she went 90 miles in 3 hours

Step-by-step explanation:

in 20 minutes, she went 10 miles.

so in 1 hour, we multiply both 10 and 20 by 3

in 1 hour, Amelia drives 30 miles

we multiply this by 3,

and we get 90 miles in 3 hours :)

Answer:

  a) q = 15 at minimum average cost; q = 10 at minimum marginal cost

  b) marginal cost = average cost = 225 at q = 15

Explanation:

The average cost is the total cost divided by the number of units.

  A = C/q = 300 -10q +1/3q^2

The marginal cost is the derivative of the total cost.

  M = 300 -20q +q^2

__

a) The minimum average cost is where its derivative is zero.

  A' = 0 = -10 +2/3q   ⇒   q = 15

The minimum marginal cost is where its derivative is zero.

  M' = -20 +2q   ⇒   q = 10

__

b) The average cost for 15 units produced is ...

  A(15) = 300 -10(15) +1/3(15^2) = 225

The marginal cost at that same production level is ...

  M(15) = 300 -20(15) +15^2 = 225

The average cost and marginal cost are equal at the minimum average cost.

Step-by-step explanation:

- 7(x + 4) - 4= - 32

Add 4 to each side

- 7(x + 4) - 4+4= - 32+4

- 7(x + 4) = - 28

Divide by -7

- 7(x + 4) /-7= - 28/-7

x+4 = 4

Subtract 4 from each side

x+4-4 = 4-4

Answer:

The most basic fact about triangles is that all the angles add up to a total of 180 degrees. The angle between the sides can be anything from greater than 0 to less than 180 degrees. The angles can't be 0 or 180 degrees, because the triangles would become straight lines.

Answer:

im good

Step-by-step explanation:

The easiest and most time-effective way to approach this problem is to use the quadratic formula:

[tex]x=\frac{-b\pm\sqrt{ b^2-4ac}}{2a}[/tex],

where a = 2, b = -1, and c = 4. (We get this from the general quadratic: ax² + bx + c.)

When we plug in our numbers, we get [tex]x=\frac{1\pm\sqrt{1-32}}{4}[/tex] which also equals [tex]\frac{1\pm i\sqrt{31}}{4}[/tex], or the first choice!
