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

Step-by-step explanation:
The area of the postcard pictured below is 24 square inches. What is the width b of the message section (in inches)? Pick the equation that would best model this situation.
A. 4(b + 3) = 24
B. 3(4 + b) = 24
C. 4(b - 3) = 24
D. 3(b - 4) = 24
Answer:
Step-by-step explanation:
4(b + 3) = 24
Answer:
A. 24 = 4(b + 3)Step-by-step explanation:
Area is equal to length times width. In this case, the length is b + 3 (since both b and 3 are part of the width, with the length being 4.
Substitute into the equation for area:
a = lw
a = 4(b + 3)
The area is 24, so the final answer is:
A. 24 = 4(b + 3)Chaz kept a record of how many gallons of gas he purchased each day last week. Drag and drop the days into the correct boxes to order the days from the least amount of gas Chaz purchased to the greatest amount of gas Chaz purchased.
Day Gas (in gallons)
Monday 4.5
Tuesday 3.6
Wednesday 4.252
Thursday 3.71
Friday 4.255
Answer:
The arrangement of days from least to greatest according to number of gallons is:
Tuesday
Thursday
Wednesday
Friday
Monday
Step-by-step explanation:
The given amount of gallons is in decimal form and we have to arrange the numbers in the order from least to greatest.
4.5 is the largest number in the given numbers.
Then comes 4.252 and 4.255
As 0.252<0.255 so 4.252 will be smaller.
The smallest number is 3.6
Arranging the numbers, we get
3.6
3.71
4.252
4.255
4.5
Now arranging the corresponding day to each number,
The arrangement of days from least to greatest according to number of gallons is:
Tuesday
Thursday
Wednesday
Friday

Najat is selling raffle tickets. The table shows the cost (in dollars) of buying different numbers of tickets.
Using x for the number of tickets and y for the cost, do the following.
Write an equation relating x and y
Answer:
The equation relating x and y is: y=4x
Step-by-step explanation:
Let x represent number of tickets
and y represent cost
a) Plot the ordered pairs
The ordered pairs (1,4),(2,8),(3,12),(4,16) is plotted in figure attached.
b) Write an equation relating x and y
y= 4x
Now checking by putting values of x to see, if we get values of y
if x=1, then y=4x => y=4*1 =>y=4
if x=2 then y=4x => y=4*2 =>y=8
if x=3 then y=4x => y=4*3 =>y=12
So, we get same values as table.
The equation relating x and y is: y=4x
If y = -6 when x = 16, find y when x = 8.
Answer:
y=-3

Vertical Line Test - A function's x-values must have only 1 y-value corresponding to it. If the function fails to pass this, it is not a function.Step-by-step explanation:
When we apply the Vertical Line Test to the 1st graph, it does not pass it. Therefore, the 1st graph is not a function.
When we apply the Vertical Line Test to the 2nd graph, it does not pass it. Therefore, the 2nd graph is not a function.
When we apply the Vertical Line Test to the 3rd graph, it does not pass it. Therefore, the 3rd graph is not a function.
When we apply the Vertical Line Test to the 4th graph, it does pass it. Therefore, the 4th graph is a function.

Write sin(x+1) in terms of unshifted sine and cosine. Write your answer using decimals.
Please provide explanation, I’m confused.
Answer: sin(x + 1) = 0.841*cos(x) + 0.540*sin(x)
Step-by-step explanation:
Here we can use the relation:
Sin(a + b) = sin(a)*cos(b) + sin(b)*cos(a)
In this case we have:
sin(x + 1)
This means that the graph of sin(x) is shifted one unit to the left.
But we can write this, using the above relation, as:
sin(x + 1) = sin(x)*cos(1) + sin(1)*cos(x)
Now we have no longer a shift, and we can replace:
sin(1) = 0.841
cos(1) = 0.540
Then:
sin(x + 1) = 0.841*cos(x) + 0.540*sin(x)

write an equation of the line that passes through (-1, 3) and has a slope of -4
Answer:
y = -4x - 1
Step-by-step explanation:
We are given the slope so we can find the y intercept using slope intercept [ y = mx + b ]
y = -4x + b
3 = -4(-1) + b
3 = 4 + b
-1 = b
Now, put everything we know and solved for back into the formula.
y = -4x - 1
