Answer:

1) 17 units

Step-by-step explanation:

using pythagoean theorm you need to square 8 and 15 and add them and then take the sqaure root and finally you will get 17

Answer:

since they said ‘when’ x = -2

just substitute -2 for x

x^3 - x + 4

substitute to get

-2^3 - (-2) + 4

which becomes

-8 + 2 + 4 = -8+6 = -2

Answer:

C, -2

Step-by-step explanation:

-2 x -2 x -2 = -8

-8- -2 = -8 + 2 = -6

-6+4=-2

Answer:

70, 84, and 116

Step-by-step explanation:

(x) + (x + 14) + (2x - 24) + 90 = 360

4x - 10 + 90 = 360

4x = 280

x = 70

x + 14 = 84

2x - 24 = 116

I just did it and it's 3 who came up with this

Answer:

Im not too sure abt a but for b i belive that its $24

The graph of a linear inequality in one variable is a number line. Use an open circle for < and > and a closed circle for ≤ and ≥.

The graph for x > -3

<( not the writeing part UGH!!

Inequalities that have the same solution are called equivalent. There are properties of inequalities as well as there were properties of equality. All the properties below are also true for inequalities involving ≥ and ≤. The addition property of inequality says that adding the same number to each side of the inequality produces an equivalent inequalit. The subtraction property of inequality tells us that subtracting the same number from both sides of an inequality gives an equivalent inequality. The multiplication property of inequality tells us that multiplication on both sides of an inequality with a positive number produces an equivalent inequality. Multiplication in each side of an inequality with a negative number on the other hand does not produce an equivalent inequality unless we also reverse the direction of the inequality symbol. The same goes for the division property of inequality.Division of both sides of an inequality with a positive number produces an equivalent inequality.And division on both sides of an inequality with a negative number produces an equivalent inequality if the inequality symbol is reversed.To solve a multi-step inequality you do as you did when solving multi-step equations. Take one thing at the time preferably beginning by isolating the variable from the constants. When solving multi-step inequalities it is important to not forget to reverse the inequality sign when multiplying or dividing with negative numbers.

Answer:

2x² + 10x - 5

Step-by-step explanation:

Using synthetic division to perform the division

3 | 2   4   - 35   15

    ↓   6     30  - 15

  --------------------------

    2  10     - 5     0 ← remainder

Since remainder is zero then (x - 3) is a factor of 2x³ + 4x² - 35x + 15

quotient is 2x² + 10x - 5

13/15 is the answer because if you subtract 6/5 and 1/3 you get .86667 and if you convert that to a fraction it would be 13/15.

Step-by-step explanation:

y = 4x - 1

2x + 2y = 3

2x + 2(4x - 1) = 3

2x + 8x - 2 = 3

10x = 3 + 2

x = 5/10

x = 1/2

y = 4x - 1

y = 4(1/2) - 1

y = 2 - 1

y = 1

(x,y) = (1/2 , 1)

Answer:

sqrt(1/m+4)

Step-by-step explanation:

n^2-1/m=4

n^2=1/m+4

n=sqrt(1/m+4)

The value of the equation is n = √ ( 4 + 1/m )

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

n² - 1/m = 4   be equation (1)

On simplifying the equation , we get

Adding 1/m on both sides of the equation , we get

n² = 4 + 1/m

Taking square roots on both sides of the equation , we get

n = √ ( 4 + 1/m )

Therefore , the value of n is √ ( 4 + 1/m )

Hence , the equation is n = √ ( 4 + 1/m )

Step-by-step explanation:

Answer:

3. m1=82, m4=59. m5=98, m6=51, m7=79, m9=51, m10=129

4. m1=36, m2=90, m4=36, m5=90, m6=54, m7=126, m8=54, m9=126, m10=54, m11=36, m12=144, m13=36, m14=144

Step-by-step explanation:

3. m2=98, m3=23, m8=70

by supplementary angles, m1 + m2 = 180, since we know m2, we have m1 = 180 - 98 = 82. by corresponding angles we have m1 = m3 + m4, since we know m1 and m3, we have m4 = 82 - 23 = 59. again by supplementary angles, m3 + m4 + m5 = 180. we know m3 and m4 so m5 = 180 - 23 - 59 = 98. by alternate interior angles m4 = m7, so m7 = 59. by supplementary angles m6 + m7 + m8 = 180 so m6 = 180 - 70 - 59 = 51. by corresponding angles m6 = m9 so m9 = 51. by supplementary angles m9 + m10 = 180 so m10 = 129

4. m3=54

m2 is a right angle so m2=90. by complementary angles m3 + m4 = 90 so m4 = 36. by vertical angles m1=m4 so m1=36. by vertical angles m2=m5 and m3=m6 so m5=90 and m6=54. by corresponding angles m7 = m2+m1 so m7=126. by supplementary angles m7+m8 = m7+m10 = 180 so m8=10=54. by vertical angles m7=m9 so m9=126. by corresponding angles m1=m11 and m3=13 so m11 and m13 = 54. by supplementary angles m12+m13= m11+m14 = 180, so m12 = m14 = 144

Answer:

x = 10

Step-by-step explanation:

2(1+5x)-3x=72

Distribute

2 + 10x -3x = 72

Combine like terms

2+7x=72

Subtract 2 from each side

2+7x-2 = 72-2

7x = 70

Divide by 7

7x/7 = 70/7

x = 10
