simplify 9 - 8b + 6b

Answers

Answer 1

Answer:

9-2b should be your answer.

Answer 2
Simplifying
9 + -8b + 6b = 0

Combine like terms: -8b + 6b = -2b
9 + -2b = 0

Solving
9 + -2b = 0

Solving for variable 'b'.

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

Add '-9' to each side of the equation.
9 + -9 + -2b = 0 + -9

Combine like terms: 9 + -9 = 0
0 + -2b = 0 + -9
-2b = 0 + -9

Combine like terms: 0 + -9 = -9
-2b = -9

Divide each side by '-2'.
b = 4.5

Simplifying
b = 4.5

Which equation does the graph below represent?
y = 1 x
y = 4x
y = _ 1x
y = -4x

Answers

Answer:

Y=-4x

Step-by-step explanation:

Whenever you solve for slope, and the slope is 1, never write 1 in the equation. Write either -x or x. Let's take two coordinates, one which is (0, 0), which is the origin, and (1, -4). To find the slope, we insert the first coordinate and second coordinate values into the equation (Y2-Y1)/(X2-X1). We can insert these coordinates to get (-4 - 0)/(1 - 0), which simplifies to (-4)/1, which further simplifies to -4. Since the Y-intercept is zero, there is no value of B in the equation, which leaves the equation as Y=-4x

1. Conrad spent $48 on art supplies. The canvas for each of his paintings is an additional $2. He plans to sell his paintings for $10. a. Write an equation that could be used to find the number of paintings (p) he will need to sell to break even.

Thanks​

Answers

Equation: 48+2p=10p
Answer: P=6
Solution: 48+ 2p=10p
Subtract 2p from both sides. It will then make the equation 48=8p.
Divide both sides by 8 to get p alone. 48/8=6
P=6
:)

The equation for break even is 8P = 48

What is an Equation ?

An equation is an expression that states the equality of two things expressed in different form.

In the given question

Conard spent $48 for art supplies

Canvas costs $2

He plans to sell his painting for $10

Without the canvas his paintings costs $(10 - 2)

= $8

So, no. of paintings (P) to break even he needs to sell

8P = 48

P = 6

∴ Conard needs to sell 6 paintings to break even.

When 2 lines are parallel to each other mean than they have same gradient
y=5x +2
Gradient=5

Let the parallel equation be y=5x +c
Since this equation pass through (4,7), means that the point satisfy the parallel equation
7=5(4)+c
C=7-20=-13

Square root of 50 estimated to the nearest integer

Answers

Answer:

square root of 50 estimated to the nearest integer is, 7.1

Step-by-step explanation:

step 1. the square root of 50 is 7.07106781186548

step 2. reduce is 7.07

step 3. round 7.07 so you only have one digit after the decimal point to get the answer., 7.1

Answer:

7

Step-by-step explanation:

Consider perfect squares either side of 50, that is

49 < 50 < 64, thus

[tex]\sqrt{49}[/tex] < [tex]\sqrt{50}[/tex] < [tex]\sqrt{64}[/tex] , that is

7 < [tex]\sqrt{50}[/tex] < 8

Since 50 is nearer to 49 than it is to 64, then

[tex]\sqrt{50}[/tex] ≈ 7 ( to the nearest integer )

−8y−13=14y+11 what is the answer?

Answers

Answer:

y = -12/11

Step-by-step explanation:

-8y - 13 = 14y + 11

-8y - 14y = 11 + 13

-22y = 24

y = 24/-22

y = -12/11

Check:

-8*-12/11  -  13 = 14*-12/11 + 11

96/11  -  13 = -168/11  +  11

96/11 - 143/11 = -168/11 + 121/11 = -47/11

A store employee creates a display of sleds priced at $40 apiece. The store paid $32 for each sled. What is the mark-up percentage

Answers

Answer:

Mark-up percentage is 25%.

Step-by-step explanation:

From the question, the store bought each sled at $32 which is the cost price. The sled was display for sale at $40 apiece.

Mark-up percentage = [tex]\frac{selling price - cost price}{cost price}[/tex] x 100%

But,

selling price - cost price = $40 - $32

                                        = $8

So that,

Mark-up percentage = [tex]\frac{8}{32}[/tex] x 100%

                                  = 0.25 x 100%

                                  = 25%

Therefore, the mark-up percentage is 25%.

0.25 kg. One is traveling at 2 m/s. The other is at rest. What is the momentum of
this group of objects?

Answers

Given :

Two hockey of same mass.

One is travelling at a speed of 2 m/s.

Other is in rest or 0 m/s.

To Find :

The momentum of  this group of objects.

Solution :

Since , no external force is applied , so momentum will remains same :

Momentum of group of objects ,

[tex]M = mv_1^2+mv_2^2\\\\M = 0.25\times 2^2+0.25\times 0\\\\M=1 \ kg \ m/s[/tex]

Therefore , momentum of the system is 1 kg m/s.

Hence , this is the required solution.

what is the absolute value of 2.3

Answers

Answer:  2.3

The absolute value of any positive number is that number itself.

If you take the absolute value of a negative number, then just erase the negative sign and you have your answer.

The absolute value is never negative. It represents distance from that value to 0 on the number line.

So saying |2.3| = 2.3 means the number 2.3 is exactly 2.3 units away from 0 on the number line.

Another example would be |-7| = 7 showing that from 0 to -7 is 7 spaces.

The required absolute number of 2.3 is also 2.3.

GIven that,
An absolute number of the value 2.3 is to be determined.

What are functions?

Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.

The absolute number is defined as the outcome of the modulus function is called the absolute number or all natural numbers are examples of absolute numbers.

Here,
For the absolute value,
f(x) = |x|
f(2.3) = |2.3|
(since |x| = x or | -x  | = x )
f( 2.3 ) = 2.3

Thus, the required absolute number of the value 2.3 is 2.3 itself.
