It is possible to solve this problem without using algebra and equations.
One number is 7 more than the other, but they add to 25.
If you subtract the difference of 7 first, you will be left with the sum of two equal numbers.
25

18
18
÷

=
9
The one number is 9 and the other is 7 more than 9, so (9+7 = 16)
The numbers are 9 and 16.
Check: 9+16 = 25#
Answer:
The pair of numbers that has a sum of 45 and a difference of 5 is (B) 25 and 20.
Step-by-step explanation:
26 + 19 = 45 and 26 - 19 = 3
25 + 20 = 45 and 25 - 20 = 5
24 + 21 = 45 and 24 - 21 = 3
26 + 21 = 47 and 26 - 21 = 5

The graph below shows f(x), which represents a parent function, and g(x), which represents a translation of that function.
On a coordinate plane, 2 exponential functions are shown. f (x) decreases in quadrant 2 and approaches y = 0 in quadrant 1. It goes through (negative 3, 8) and crosses the y-axis at (0, 0.5). g (x) decreases in quadrant 2 and approaches y = 0 in quadrant 1. It goes crosses the y-axis at (0, 14) and goes through (1, 5) and (2, 2).
Which statements about the functions are true? Check all that apply.
f(x) = (one-half) Superscript x
g(x) = (one-half) Superscript x + 4 – 2
The ranges of both functions are the same.
The domains of both functions are the same.
The translation from f(x) to g(x) is right 4 units and down 2 units.
Answer:
A. f(x) = (one-half) Superscript x
D. The domains of both functions are the same.
E. The translation from f(x) to g(x) is right 4 units and down 2 units.
The answers are A, D, and E
Step-by-step explanation:
Edge 2020
The statements about the functions are true A. [tex]f(x) = (1/2)^x[/tex]
D. The domains of both functions are the same.
E. The translation from f(x) to g(x) is right 4 units and down 2 units.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x).
We are given that On a coordinate plane, 2 exponential functions are shown. f (x) decreases in quadrant 2 and approaches y = 0 in quadrant 1.
When evaluated in zero we have:
f(0) = 2(1/2)^0 = 2
So it crosses through the point (0, 2).
And when evaluated in x = 1, then
f(1) = 2(1/2)^1 = 1
Then it also passes through (1, 1). It goes crosses the y-axis at (0, 14) and goes through (1, 5) and (2, 2).
The answers are A, D, and E

increased by 5: + 5
7 less than: - 7
twice the number: 2n
That gives us the following:
3n + 5 = 2n - 7
You only asked for the equation, not to actually help you solve for n, for note. If you do, just subtract 2n from both sides, and then subtract 5 from both sides.

4. Find CD and X . (3 points) x ^ 3 + 20 30 D x ^ 8 + 22x - 120 will mark brainliest
Answer:
CD = 15
x = 5
Step-by-step explanation:
Since BF ≅ FD and AE ≅ EC, then [tex]EF = \frac{AB + CD}{2}[/tex]
So, [tex]30 = \frac{x^{2} +20 + x^{2} + 22x - 120}{2}[/tex]
[tex]60 = 2x^{2} + 22x - 100[/tex]
[tex]2x^{2} + 22x - 160 = 0[/tex]
[tex]2(x^{2} + 11x - 80) = 0[/tex]
2(x - 5)(x + 16) = 0
x = 5 or x = -16
If x = 5, then CD = [tex]5^{2} +22(5) - 120 = 25 + 110 - 120 = 15[/tex]
Ix x = -16, then CD = will be a negative number which it cannot be.

which expression is equivalent to x^6 - 16x^2?
Answer:
Theory : A difference of two perfect squares, A2 - B2 can be factored into (A+B) • (A-B)
Proof : (A+B) • (A-B) =
A2 - AB + BA - B2 =
A2 - AB + AB - B2 =
A2 - B2
Note : AB = BA is the commutative property of multiplication.
Note : - AB + AB equals zero and is therefore eliminated from the expression.
Check : 16 is the square of 4
Check : x4 is the square of x2
Factorization is : (x2 + 4) • (x2 - 4)
Equivalent expressions are expressions with equal values
The equivalent expression of [tex]\mathbf{x^6 - 16x^2}[/tex] is [tex]\mathbf{x^2(x + 2)(x - 2)(x^2 + 4)}[/tex]
The expression is given as:
[tex]\mathbf{x^6 - 16x^2}[/tex]
Factor out x^2
[tex]\mathbf{x^6 - 16x^2 = x^2(x^4 - 16)}[/tex]
Express x^4 as (x^2)^2
[tex]\mathbf{x^6 - 16x^2 = x^2((x^2)^2 - 16)}[/tex]
Express 16 as 4^2
[tex]\mathbf{x^6 - 16x^2 = x^2((x^2)^2 - 4^2)}[/tex]
Apply difference of two squares
[tex]\mathbf{x^6 - 16x^2 = x^2((x^2 - 4)(x^2 + 4))}[/tex]
Express 4 as 2^2
[tex]\mathbf{x^6 - 16x^2 = x^2((x^2 - 2^2)(x^2 + 4))}[/tex]
Apply difference of two squares
[tex]\mathbf{x^6 - 16x^2 = x^2(x + 2)(x - 2)(x^2 + 4)}[/tex]
Hence, the equivalent expression of [tex]\mathbf{x^6 - 16x^2}[/tex] is [tex]\mathbf{x^2(x + 2)(x - 2)(x^2 + 4)}[/tex]

Answer:
The area of a rectangle is l x w. So the area of the square is 10 x 10 = 100
The area of a circle is
[tex]\pi \times {r}^{2} [/tex]
The radius of all the circles is 2 inches.
[tex]\pi \times {2}^{2} = \pi \times 4 \: or \: 4\pi[/tex]
There are 4 circles so the area of all four is
[tex]4 \times (4\pi) \: or \: 16\pi[/tex]
To find the area of the shaded part of the square, subtract the area of all the circles, because they are not shaded, from the area of the square, because it is shaded. The difference will be the area of the shaded portion.
[tex]area \: = 100 - 16\pi[/tex]
[tex]area = 100 - 50.6548[/tex]
So the area is approximately 50 Sq in

simply combining like teams 3a-2b-ab-(a-b+ab)-4ab+2b-a if l write tge answers as 1a- 6ab is it correct ?
Answer:
-6 a b + b + a
Step-by-step explanation:
Simplify the following:
-(a - b + a b) - a b - 4 a b + 2 b - 2 b + 3 a - a
Hint: | Group like terms in 3 a - 2 b - a b - (a b - b + a) - 4 a b + 2 b - a.
Grouping like terms, 3 a - 2 b - a b - (a b - b + a) - 4 a b + 2 b - a = -(a b - b + a) + (-a b - 4 a b) + (3 a - a) + (2 b - 2 b):
-(a b - b + a) + (-a b - 4 a b) + (3 a - a) + (2 b - 2 b)
Hint: | Combine like terms in -a b - 4 a b.
a b (-1) + a b (-4) = -5 a b:
-(a b - b + a) + -5 a b + (3 a - a) + (2 b - 2 b)
Hint: | Combine like terms in 3 a - a.
3 a - a = 2 a:
-(a b - b + a) - 5 a b + 2 a + (2 b - 2 b)
Hint: | Look for the difference of two identical terms.
2 b - 2 b = 0:
-(a b - b + a) - 5 a b + 2 a
Hint: | Distribute -1 over a b - b + a.
-(a b - b + a) = -a b + b - a:
-a b + b - a - 5 a b + 2 a
Hint: | Group like terms in -a b - 5 a b + b + 2 a - a.
Grouping like terms, -a b - 5 a b + b + 2 a - a = (-a b - 5 a b) + b + (-a + 2 a):
(-a b - 5 a b) + b + (-a + 2 a)
Hint: | Combine like terms in -a b - 5 a b.
a b (-1) + a b (-5) = -6 a b:
-6 a b + b + (2 a - a)
Hint: | Combine like terms in 2 a - a.
2 a - a = a:

Jordan wants to run a 12-kilometer race. He knows how fast he can run a mile, so he wants to convert the length of the race to miles. How many miles long is the race?
Answer:
7.45645 miles
Step-by-step explanation:
12 divided by 1.609 equals 7.45645
You divide 12 kilometers by to get miles.
Jordan has to race 7.45645 miles.
What is Unit Conversion?The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles.
Given:
Jordan wants to run a 12-kilometer race.
We know 1 Km= 0.621371 miles
So, To convert 12 Km into miles
12 Km = 12 x 0.621371
= 7.45645 miles
Hence, Jordan has to race 7.45645 miles.

What is sine of an angle?
The sine of an angle is the trigonometric ratio of the opposite side to the hypotenuse of a right triangle containing that angle.
What is tangent of an angle?The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side.
According to the given question.
We have [tex]cotA = \frac{5}{2}[/tex]
⇒[tex]tanA = \frac{2}{5}[/tex]
From the definition of tangent of an angle.
In right angled triangle PQR, we can say that
PR = 2 and RQ = 5
Therefore,
[tex]x^{2} = (PR)^{2} +(RQ)^{2}[/tex]
⇒[tex]x^{2} =(2)^{2} +(5)^{2}[/tex]
⇒[tex]x^{2} = 4 + 25[/tex]
⇒[tex]x^{2} = 29[/tex]
⇒[tex]x = \sqrt{29}[/tex]
Since,
Sine of an angle = opposite side/ Hypotenuse
In triangle PQR
The opposite side w.r.t angle A is PR.
And the hypotenuse is PQ.
Therefore, sine of an angle A is given by
[tex]sinA= \frac{2}{\sqrt{29} }[/tex]
⇒[tex]sinA = \frac{2}{\sqrt{29} } \frac{\sqrt{29} }{\sqrt{29} }[/tex]
⇒[tex]sinA = \frac{2\sqrt{29} }{29}[/tex]
Hence, the value of sin A is [tex]\frac{2\sqrt{29} }{29}[/tex].
