Answer:

(4) multiply 3 by 4

Step-by-step explanation:

(2-3•4+5)²

Firstly multiply 3 by 4

(2-12+5)²

Then add 2 and 5

(-12+7)²

Now subtract -12 from 7

-5²

= (-5)(-5)

= 25

Thus, the first step in simplifying the expression (2-3•4+5)^2 is (4) multiply 3 by 4.

Answer:

Step-by-step explanation:

17c. We cannot see the entire diagram, but based on what we can see, if we assume that segments FG and DH are parallel, then angles D and G correspond. The similarity statement is then ...

  ΔDEH ~ ΔGEF

__

Corresponding angles are congruent, and are listed in the same order in the similarity statement. This means we have ...

  ∠D ≅ ∠G = 89° . . . . answer to 17b

  ∠E ≅ ∠E = 69°

  ∠H ≅ ∠F = 22° . . . . answer to 17a

_____

Additional comment

The second choice listed for part 17c can be rejected simply on the basis that ΔEGH does not exist in the figure. Points G and H are not in the same triangle.

Answer:

Acute

Step-by-step explanation:

So, straight would be a line, right would be like a corner of a square, acute would be less than a right, and obtuse would be more than a right but less than a straight.

Answer:

-6

Step-by-step explanation:

40-16=24

24/-4=-6

(b + c) is equal to the product of -4 and -6.

The product of two numbers is the result you get when you multiply them together.

Given that b = 40 and c = -16

(b + c) = 40 -16 = 24

24 = -4*-6

Hence, (b + c) is equal to the product of -4 and -6.

-Chetan K

Answer:

20%

Step-by-step explanation:

Use the percent change formula: difference = % * original cost

12 - 10 = 2

The difference is 2 and the original cost is 10. Now, we have the equation

2 = % * 10. We don’t know the percentage right? So now we have to find the percentage. To do this, you will have to do 2 divided by 10, which is 0.20. Lastly, we have to turn 0.20 into a percentage by multiplying it by 100, leaving you with 20%. So therefore, 20% is the percent increase. Hope this helps!

Answer:

Well, x^2(x+5)(x−6)>0= x<-5 or x>4

Step-by-step explanation:

Just have to simplify it as I can't type the equations right now.

The polynomial expression of inequality is x² ( x + 5 ) ( x - 6 ) > 0 is given by the values ( x < -5 ) and ( x > 6 )

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

x² ( x + 5 ) ( x - 6 ) > 0

So , the values of x that are greater than 0 is given by

x² > 0

So , the value of x > 0

when ( x + 5 ) > 0

Subtracting 5 on both sides , we get

x < -5

when ( x - 6 ) > 0

Adding 6 on both sides , we get

x > 6

So , the inequalities are ( x < -5 ) and ( x > 6 )

Hence , the polynomial inequality is solved

Step-by-step explanation:

Answer:

$95.89875

Step-by-step explanation:

The original price of the necklace is 119.5. And we are subtracting 25% from this. 119.5 - 25% = 119.5 - 1/4 since 25% is 25/100 which is also 1/4.

So without tax, the price of the necklace is 119.5 - 29.875 which is 89.625.

The tax is 7%. So we should add 89.625 to 7%. This is complicated, but it should result in 95.89875.

If we round this to the nearest cent, it should be $95.9.

Answer:

1 - 58°

2 - 122°

3 - 58°

Step-by-step explanation:

Important notes:

• Vertical Angles Theorem - The angles that are opposite to each other on an intersection of 2 lines are always congruent.

• Linear Pair - The two angles that are formed when a straight line is split. Linear pairs are supplementary angles.

• Supplementary Angles - An angle pair whose total measure = 180°.

Angle 1 is supplementary to the angle with measure 122°.

So, ∡1 = 180 - 122.

∡1 = 58°

Based on the Vertical Angles Theorem, ∡1 ≅ ∡3, so ∡3 is also 58°.

Based on the Vertical Angles Theorem, ∡2 ≅ 122°, so ∡2 = 122°.

∡1 = 58°

∡2 = 122°

∡3 = 58°

Answer:

[tex]\boxed {\boxed {\sf (5, -3)}}[/tex]

Step-by-step explanation:

We are asked to solve the system of equations by substitution. We must isolate a variable and plug it into the other equation.

We are given these 2 equations;

[tex]2x-3y=19[/tex]

[tex]x-2y=11[/tex]

1. Isolate a Variable

We can easily isolate x in the 2nd equation. 2y is being subtracted from x. The inverse operation of subtraction is addition. Add 2y to both sides of the equation.

[tex]x-2y+2y=11 +2y \\x= 11+2y[/tex]

2. Substitute and Solve for y

x is equal to 11 + 2y, so we can substitute this expression in for x in the 1st equation.

[tex]2x-3y=19[/tex]

[tex]2(11+2y)-3y=19[/tex]

Now we can solve for y by isolating the variable First, distribute the 2. Multiply each term in parentheses by 2.

[tex](2*11) + (2*2y) -3y = 19[/tex]

[tex]22 + 4y-3y = 19[/tex]

Combine the like terms.

[tex]22+y=19[/tex]

22 is being added to y. The inverse operation of addition is subtraction. Subtract 22 from both sides of the equation.

[tex]22-22+y=19-22\\y= 19-22 \\y= -3[/tex]

3. Solve for x

We know that y is equal to -3, so we can plug it back into either original equation and solve for x. Let's use the 2nd equation.

[tex]x-2y=11[/tex]

[tex]x-2(-3)=11[/tex]

Multiply -2 and -3.

[tex]x+6=11[/tex]

6 is being added to x. The inverse operation of addition is subtraction. Subtract 6 from both sides of the equation.

[tex]x+6-6=11-6\\x=11-6 \\x=5[/tex]

We found that y=-3 and x=5. Coordinate points are written as (x,y), so the solution for this system of equations is (5, -3).
