Answer:
19, 2
Step-by-step explanation:
let the 2 numbers be x and y with x > y , then
x + y = 21 → (1)
x - y = 17 → (2)
Add the 2 equations term by term to eliminate y , that is
2x = 38 ( divide both sides by 2 )
x = 19
substitute x = 19 into (1) for value of y
19 + y = 21 ( subtract 19 from both sides )
y = 2
The 2 numbers are 19 and 2

June was thinking of a number. June doubles it and gets an answer of 98.9. What was the original number?
Answer: 49.45
Step-by-step explanation:
From the information, we are informed that June was thinking of a number and then doubles it and gets and gets an answer of 98.9.
Let the number be represented by x.
Since she doubles it, thus implies that:
2x = 98.9
x = 98.9 / 2
x = 49.45
The number is 49.45

If y is a positive integer, for how many different values of y is [tex]\sqrt[3]{144\y}[/tex]a whole number?
Answer:
2
Explanation:
I'll explain later, it has to do with prime factors, and perfect cubes.
The two values of y that work are 18, and 144.
³√(144/18) = ³√(8) = 2 [whole number]
³√(144/144) = ³√(1) = 1 [whole number]
On a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and curves up and increases in quadrant 1.
What are the domain and range of the function on the graph?
The domain includes all integers, and the range is y ≥ 0.
The domain includes all integers, and the range is y > 0.
The domain includes all real numbers, and the range is y ≥ 0.
The domain includes all real numbers, and the range is y > 0.
The graph will begin at a lower point on the y-axis.
The graph will increase at a faster rate.
The graph will increase at a slower rate.
The y-values will continue to increase as x-increases.
The y-values will each be less than their corresponding x-values.
Answer:
The domain of the function i.e. the value of x can be any real number and the range of the function is y > 0.
Step-by-step explanation:
On a coordinate plane, an exponential function approaches y = 0 in quadrant 2 and curves up and increases in quadrant 1.
Therefore, as x tends to - ∞, the y-value tends to 0 but not equal to zero and as x tends to +∞, the y-value also tends to +∞.
Hence, the domain of the function i.e. the value of x can be any real number and the range of the function is y > 0. (Answer)

Which expression is equivalent to 13 square root 22b - 10 square root 22b, if b>0?
A. 23 square root 22b
B. 130 square root 22b
C. 3 square root b^2
D. 3 square root 22b
Given:
The expression is
[tex]13\sqrt {22b}-10\sqrt{22b}, b>0[/tex]
To find:
The equivalent expression.
Solution:
We have,
[tex]13\sqrt {22b}-10\sqrt{22b}[/tex]
Taking out common factors.
[tex]=(13-10)\sqrt {22b}[/tex]
[tex]=(3)\sqrt {22b}[/tex]
[tex]=3\sqrt {22b}[/tex]
The expression [tex]3\sqrt {22b}[/tex] is equivalent to the given expression.
Therefore, the correct option is D.

Bring 8/(a-x) to a denominator of x-a
Answer:
[tex]-\frac{8}{x-a}[/tex]
Step-by-step explanation:
[tex]\frac{8}{a-x}[/tex]
we can take common factor of -1 in the denominator
[tex]\frac{8}{-(-a+x)}=\frac{8}{-(x-a)}[/tex]
and now multiply and divide by -1
[tex]\frac{8}{-(x-a)}\cdot \frac{-1}{-1}=\frac{-8}{x-a}=-\frac{8}{x-a}[/tex]

The ratio x: y is 1:3
Which of the following statements are correct?
A x is 1/3 of y
B y is 3/4 of (x + y)
x is 1/4 of y
y is 3/4 of x
Answer:
Option A
Step-by-step explanation:
x : y = 1 : 3
This can be also written as
[tex] \frac{x}{y} = \frac{1}{3} [/tex]
Multiplying y on both the sides
[tex] = > \frac{x}{y} \times y = \frac{1}{3} \times y[/tex]
[tex] = > x = \frac{1}{3} \times y[/tex]
Hence , x is one-third of y
Answer:
A and B
x is [tex]\frac{1}{3}[/tex] of y
AND
y is [tex]\frac{3}{4}[/tex] of (x+y)
Step-by-step explanation:
x:y is 1:3
=> y is bigger than x
=> y is 3x bigger than x
=> y = 3 lots of x
=> [tex]y =[/tex] [tex]3x[/tex]
=> [tex]\frac{y}{3}[/tex] [tex]= x[/tex]
=> [tex]\frac{1}{3} y[/tex] [tex]= x[/tex]
So x is [tex]\frac{1}{3}[/tex] of y
y is [tex]\frac{3}{4}[/tex] of (x+y)
If x = 1 and y = 3 (substitute in values)
=> 3 is [tex]\frac{3}{4}[/tex] of (4)
=> 3 is [tex]\frac{3}{4}[/tex](4)
=> 3 is ([tex]\frac{3}{4}[/tex]x4)
=> 3 = 3
Therefore, y is [tex]\frac{3}{4}[/tex] of (x+y) is true
So the answers are:
x is [tex]\frac{1}{3}[/tex] of y
AND
y is [tex]\frac{3}{4}[/tex] of (x+y)
A triangle has interior angles of (x+5) (x-5) and (2x) what is the measure of the largest interior angle?
Answer:
90
Step-by-step explanation:
interior angles of all triangles add up to 180 degrees
180=x+5+x-5+2x
180=4x
45=x
plug back in to find largest angle
2 (45) = 90

Solve |x+4|=6 need help for a quiz
Answer:
down below
Step-by-step explanation:
set up two equations:
x + 4 = 6 x + 4 = -6
solve both:
x = 2 x = -10
plug it back in to the original equation:
|2 + 4| = 6. |-10 + 4| = -6
|6| = 6. |-6| = -6
6 = 6. since absolute value is always positive:
correct. |6| = -6
6 does not = -6
write both of these down if you need to show your work
