The sum of two numbers is −36. Their difference is 68. Find the numbers.
The two numbers from the equations are 16 and -52
The first number is 16
The second number is -52
What is an Equation?
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 first number be = x
Let the second number be = y
So , the equation will be
Let the sum of two numbers be = -36
And the equation will be
x + y = -36 be equation (1)
Let the difference of two numbers be = 68
And the equation will be
x - y = 68 be equation (2)
Subtracting equation (1) from equation (2) , we get
On simplifying the equation
2x = 32
Divide by 2 on both sides of the equation , we get
x = 16
The equation will be
Substituting the value of x in the equation , we get
x + y = -36
16 + y = -36
Subtracting 16 on both sides , we get
y = -52
Hence , the two numbers are 16 and -52

Answer:
x = 67°
Step-by-step explanation:
there are 180 degrees in a triangle and we know that the two corners equal the same amount. so we can set up an equation like this:
180 = 46 + 2x
so now lets subtract 46 from both sides to simplify the equation.
134 = 2x
now we can divide both sides by 2 to get our final answer.
67 = x
we can check our answer by solving this expression:
67 + 67 + 46 = ?
after adding these together, we get 180 so we know our answer is correct.
hope this helped!
Which expression is equivalent to?
Write this equation in standard form: (4, -1) m = 3
Standard form looks like this: Ax + By = C.
y - (-1) = 3(x - 4)
y + 1 = 3x - 12
y = 3x - 12 - 1
y = 3x + 13
Move 13 to left side and y to right side.
-13 = 3x - y

A relation/function is a relation/function where there is exactly one unique output/input for each output/input
Answer:
A relation has an input value which corresponds to an output value. When each input value has one and only one output value, that relation is a function. Functions can be written as ordered pairs, tables, or graphs. The set of input values is called the domain, and the set of output values is called the range.

Answer:
Vertical change = 4
Horizontal change = 1
Slope = 4
b (y-intercept) = 2
Step-by-step explanation:
From the graph (notice it as also marked with an arrow) you can get the value of "b" (also called the -intercept) is "2"
Please notice that you have entered wrong values for the slope.
By using the points (0, 2), and (1, 6) which are marked on the graph, you estimate the slope doing:
slope = vertical_change / horizontal_change = (y2 - y1) / (x2 - x1)
in our case, the vertical change (y2 - y1) is : 6 - 2 = 4
The horizontal change is (x2 - x1) = (1 - 0) = 1
Then the slope is: 4 / 1 = 4
slope = 4
and "b" (or y-intercept) is 2
What is the slope? Help please

A zoo maintains a small patch of bamboo, which it grows as a food supply for its pandas. Four weeks ago, the bamboo was 10 ft 7 in tall. Since then, the bamboo has grown 5ft 12 in. How tall is the bamboo now ?
bamboo has grown 5 ft 12 in. How tall is the bamboo now?
Answer:
16 feet and 7 inches
Step-by-step explanation:
To find how tall the bamboo is now, first add the number of feet together:
10 + 5
= 15
Then, add the inches:
7 + 12
= 19
This can be converted to 1 foot and 7 inches.
Then, add 15 to this:
= 16 feet and 7 inches
So, the bamboo is now 16 feet and 7 inches tall
The current height of the bamboo is given as 16 feet 7 inches tall.
Given that,
A zoo maintains a small patch of bamboo, which it grows as a food supply for its pandas. Four weeks ago, the bamboo was 10 ft 7 in tall. Since then, the bamboo has grown 5ft 12 in.
In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication, and division,
Here,
4 weeks ago the height of the bamboo = 10 ft 7 in
It increase by 5 ft 12 or 6 ft since then
Current height = 10.7 + 6 = 16.7 or 16 ft 7 in
Thus, the current height of the bamboo is given as 16 feet 7 inches tall.

The larger of two numbers is 9 less than four times the smaller number if the sum of
the two numbers is 26. What is the smaller number?
Answer:
7
Step-by-step explanation:
l = larger number
s = smaller number
l = 4s - 9
l + s = 26
so 4s - 9 + (s) = 26
simplify--> 5s - 9 = 26
--> 5s = 35
---> s = 7
substitute 7 for s to find l
l + 7 = 26
l = 19

Trump? Why or why not?
Answer:
Explained below.
Step-by-step explanation:
The (1 - α)% confidence interval for the population proportion is:
[tex]CI=\hat p\pm MOE[/tex]
Given:
[tex]\hat p=0.40\\MOE=0.03[/tex]

Compute the confidence interval as follows:

[tex]=0.40\pm0.03\\\\=(0.37, 0.43)[/tex]

Since the confidence interval consists of values less than 50%, it implies that there is not enough evidence to suggest that more than 50% of Americans approve of Trump.

-2 is your y-intercept so one point on your plot is (0,-2)
your slope is 1/4, rise/run
so from the y-int go up 1 and right 4, so another point is (-1,4)
and you can keep going up 1 and right 4 for as many points as you need.

the value of x for the exponential function f(x) = e^x is a set of real numbers?true or false
Answer:
a) f(x) = x^2
b) f(x) = x
c) any pair of numbers
Step-by-step explanation:
The value of the exponential function f ( x ) = eˣ has the domain as the set of all real numbers
What are the laws of exponents?When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.
The different Laws of exponents are:
mᵃ×mᵇ = mᵃ⁺ᵇ
mᵃ / mᵇ = mᵃ⁻ᵇ
( mᵃ )ᵇ = mᵃᵇ
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
m⁻ᵃ = ( 1 / mᵃ )
Given data ,
Let the exponential function be represented as A
Now , the value of A is
f ( x ) = eˣ be equation (1)
And , exponential functions have a positive base, and a variable for an exponent.
The scope of an exponential function encompasses all real numbers since all powers of a positive base are defined. All the values of the function will be positive since we begin with a positive base and powers of a positive base are always positive.
The function never accepts the value 0 or any negative number, as indicated by that. An exponential function can only be applied to positive values. Other than that, their activities are varied.
And , the domain is all real numbers and the range is all positive real numbers
Hence , the value of the exponential function is a set of real numbers
