What is the distance between -9 and 42 on the number line?
Answer:
51 is the answer to the question
Answer:
51
Step-by-step explanation:
-9 is 9 jumps from zero
42 is 42 jumps from zero
9 + 42 = 51
it would take -9 51 jumps to get to 42

Any One Know This One
Answer:
no solutions
Step-by-step explanation:
4 + 5m = 4m + 1 + m combine like terms
4 + 5m = 5m + 1 subtract 5m from each side
4 = 1
4 can never equal 1, so no value of m would allow the equation to be correct
The left side 4+5m is the same as 5m+4
Simplifying the right hand side has 4m+1+m turn into 5m+1
The original equation is equivalent to 5m+4 = 5m+1
If we subtract 5m from both sides, the 5m terms cancel leaving us with 4 = 1, but that's not a true statement.
Regardless of whatever value you pick for m, the original equation will not be true.
Earth is approximately 9.3 × 107 miles from the sun. Saturn is approximately 8.87 × 108 miles from the sun. About how much farther is Saturn from the sun than Earth is?
Answer:
Both distances are in the scientific notation:
Earth - Sun = 9.3 * 10^7 miles
Saturn - Sun = 8.87 * 10^8 miles
8.87 * 10^8 - 9.3 * 10^7 =
= 88.7 *10^7 - 9.3 * 10^7 =
= 79.4 * 10^7 = 7.94 * 10 ^8 = 794,000,000 miles
Answer: Saturn is 7.94 * 10^8 miles farther from Sun than Earth is.

write a polynomial of degree 5 with zero x=0,i square root 7, -2i
Answer:
[tex]P(x)=x^5+11x^3+28x[/tex]
Step-by-step explanation:
Roots of a polynomial
If we know the roots of a polynomial, say x1,x2,x3,...,xn, we can construct the polynomial using the formula
[tex]P(x)=a(x-x_1)(x-x_2)(x-x_3)...(x-x_n)[/tex]
Where a is an arbitrary constant.
We know three of the roots of the degree-5 polynomial are:
[tex]x_1=0;\ x_2=\sqrt{7}\boldsymbol{i}:\ x_3=-2\boldsymbol{i}[/tex]
We can complete the two remaining roots by knowing the complex roots in a polynomial with real coefficients, always come paired with their conjugates. This means that the fourth and fifth roots are:
[tex]x_4=-\sqrt{7}\boldsymbol{i}:\ x_3=+2\boldsymbol{i}[/tex]
Let's build up the polynomial, assuming a=1:
[tex]P(x)=(x-0)(x-\sqrt{7}\boldsymbol{i})(x+\sqrt{7}\boldsymbol{i})(x-2\boldsymbol{i})(x+2\boldsymbol{i})[/tex]
Since:
[tex](a+b\boldsymbol{i})\cdot (a-b\boldsymbol{i})=a^2+b^2[/tex]
[tex]P(x)=(x)(x^2+7)(x^2+4)[/tex]
Operating the last two factors:
[tex]P(x)=(x)(x^4+11x^2+28)[/tex]
Operating, we have the required polynomial:
[tex]\boxed{P(x)=x^5+11x^3+28x}[/tex]

Find the value of x that would prove y is parallel to z. State the converse used to support your answer.
Answer:
[tex] x = 15 [/tex]
Step-by-step explanation:
By the Consecutive Interior Angles Converse, if [tex] (3x + 7) + (10x - 22) = 180 [/tex], then y is parallel to z.
Solve for x
[tex] 3x + 7 + 10x - 22 = 180 [/tex]
Combine like terms
[tex] 3x + 10x + 7 - 22 = 180 [/tex]
[tex] 13x - 15 = 180 [/tex]
Add 15 to both sides
[tex] 13x - 15 + 15 = 180 + 15 [/tex]
[tex] 13x = 195 [/tex]
Divide both sides by 13
[tex] \frac{13x}{13} = \frac{195}{13} [/tex]
[tex] x = 15 [/tex]

determine the x and y intercept for the graph of 7x+3
Answer:
y-intercept is 3 and x-intercept is -3/7
Step-by-step explanation:
to find the y-intercept let x = 0 and solve for y.
y=7(0) +3
y=0+3
y=3
to find the x-intercept let y = 0 and solve for x
0 = 7x + 3
-3 = 7x
-3/7 =x
Suppose that J and K are points on the number line.
If JK = 14 and J lies at -5, where could K be located?
If there are several locations, separate them with commas.
Answer:
9, -19
Step-by-step explanation:
Given that the distance between point J and point K on a number line is 14, and the coordinate of J is -5, there are two possible coordinates that could represent the location of K.
K can either be located to the right of J, or to the left of J. Either ways, distance between J and K will still equal 14.
To the right we would have K located at: -5 + 14 = 9
To the left we can also have K located at: -5 - 14 = -19
K can be located at either 9 or -19
Solve for x. x+5.39>4.48
Answer:
[tex]\boxed {x > -0.91}[/tex]
Step-by-step explanation:
Solve for [tex]x[/tex] :
[tex]x + 5.39 > 4.48[/tex]
-Subtract [tex]5.39[/tex] on both sides:
[tex]x + 5.39 - 5.39 > 4.48 - 5.39[/tex]
[tex]x > -0.91[/tex]
So, therefore, the final answer is [tex]\boxed {x > -0.91}[/tex].
