Answer:

-15

Step-by-step explanation:

Note the rules when multiplying or dividing numbers with signs.

IF:

1) You are multiplying or dividing with two negative numbers, your answer will be positive.

2) You are multiplying or dividing with one negative and one positive number, your answer will be negative.

3) You are multiplying or dividing with two positive numbers, your answer will be positive.

Note that there is one negative term (-1) and one positive term (15). Multiply. Follow rule 2:

15 x -1 = -15

Answer:

x = -15/2

Step-by-step explanation:

Combine the expressions and isolate the variable x.

Answer:  x=10

Step-by-step explanation:

Simplifying

3x + 15 = 45

Reorder the terms:

15 + 3x = 45

Solving

15 + 3x = 45

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-15' to each side of the equation.

15 + -15 + 3x = 45 + -15

Combine like terms: 15 + -15 = 0

0 + 3x = 45 + -15

3x = 45 + -15

Combine like terms: 45 + -15 = 30

3x = 30

Divide each side by '3'.

x = 10

Simplifying

x = 10

Answer:

-.3

We were just learning these :)

Step-by-step explanation:

So let's start with the whole equation:

10 - 4x + 6 - 2x = -2x

First, combine like terms:

16 - 6x = -2x

Next, add 16 to both sides:

16 + 16 = cancels out and -2x + 16 = 14

6x = -2x

Now, divide 6 on both sides:

6 / 6 = cancels out and -2x / 6 = -.3

x = -.3

Really hope this is right!

Answer:

$84.60

Step-by-step explanation:

Multiply, since Bryon bought 3.6 cubic yards of soil and each cubic of yard cost $23.50. 3.6 x 23.50 = 84.6

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

=(20-8)/(2-1)

=12/1

m = 12

The slope of the given function is 12.

Slope or the gradient is the number or the ratio which determines the direction or the steepness of the line.

In this case, we are given three points:

Point 1: (x = 1, y = 8)

Point 2: (x = 2, y = 20)

Point 3: (x = 3, y = 32)

The slope of the function is calculated by the formula given as;

Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )

Slope =(20-8)/(2-1)

=12/1

Slope  = 12

The slope is 12.

x: 13.8924439894498

y: 6

Answer:

56.43

Step-by-step explanation:

The amount of sodium-24 that scientists can predict will remain 12 hours after the experiment started will be 56.43 mg.

Let a be the initial value and x be the power of the exponent function and b be the increasing factor.

The exponent is given as

y = a(b)ˣ

A scientist measures the amount of sodium-24 at certain times since the beginning of an experiment and the collected data can be represented with the model y = 98.8(0.9544)ˣ.

The amount of the sodium-24 that scientists can predict will remain 12 hours after the experiment started will be given as,

y = 98.8 (0.9544)¹²

y = 98.8 (0.571169)

y = 56.43 mg

The amount of sodium-24 that scientists can predict will remain 12 hours after the experiment started will be 56.43 mg.

Your question is incomplete, here is the complete form.

Points J, K and L are collinear with J between L and K.  If KJ = 2x - 3, LK = 9x + 7 and LJ = 4x - 8,  solve for x:

Answer:

The value of x is -6 ⇒ B

Step-by-step explanation:

∵ J, K, and L are collinear

→ That means they form a straight segment

∵ J is between K and L

→ That means J divides LK into two segments KJ and LJ

∴ LK = KJ + LJ

∵ LK = 9x + 7

∵ KJ = 2x - 3

∵ LJ = 4x - 8

→ Substitute them in the equation above

∴ 9x + 7 = (2x - 3) + (4x - 8)

→ Add the like terms in the right side

∵ 9x + 7 = (2x + 4x) + (-3 - 8)

∴ 9x + 7 = 6x + -11

∴ 9x + 7 = 6x - 11

→ Subtract 7 from both sides

∵ 9x + 7 - 7 = 6x - 11 - 7

∴ 9x = 6x - 18

→ Subtract 6x from both sides

∵ 9x - 6x = 6x - 6x - 18

∴ 3x = -18

→ Divide both sides by 3

∵ [tex]\frac{3x}{3}=\frac{-18}{3}[/tex]

∴ x = -6

∴ The value of x is -6

The value of x for the given problem comes to be -6.

KJ = 2x-3

LJ= 4x-8

LK = 9x+7

Points that are part of a straight line are called collinear points.

Points J, K, and L are collinear so they will be in a straight line.

So, KJ + LJ = LK

(2x-3) + (4x-8) = (9x +7)

6x - 11 = 9x + 7

-3x = 18

x= -6

Therefore, the value of x for the given problem comes to be -6.

Answer:

Time, t = 0.1143 seconds.

Step-by-step explanation:

Given that distance, d = 14m

From the equation;

d = 10 + 40t - 5t

d = 10 + 35t

Substituting the value of distance;

14 = 10 + 35t

35t = 14 - 10

35t = 4

t = 4/35

t = 0.1143 seconds.

The time needed for the ball to reach the 14-m distance is 0.1143 seconds.

The thrown ball will reach a 14-m distance after 0.114 seconds.

The relation given is:

d = 10+40t-5t

where, d = 14

In this case, we've to put the value of d into the relation and this will be:

d = 10+40t-5t

14 = 10 + 40t - 5t

Collect like terms

40t - 5t = 14 - 10

35t = 4

Divide both side by 35

35t/35 = 4/35

t = 0.114 seconds.
