Flip the equation so it is easier to solve:
[tex]4-(-6)=X[/tex]
Two negatives = A positive so:
[tex]4+6=X[/tex]
Then, add to solve the equation:
[tex]10=X[/tex]

An airplane altitude in feet during its descend can be found using the function f(x)=-200x+20,000. After new government regulations become law the descent is now modeled by the function g(x)=-200x+20,500. Which statement describes the change?
Answer:
The airplane starts its descent from an altitude 500 feet higher.
Step-by-step explanation:
Given that:
F(x) = - 200x+20,000
g(x) = -200x+20,500
The functions are written in slope intercept format :
With a negative slope, the intercept gives the point which the rate of change begins in the vertical axis :
The slope is -200 ; which means that the descent rate of the airplane is 200
The intercept value however changes from 20,000 in f(x) to 20500 in g(x). This means that the height at which descent starts is now at a height of 20500 which is (20500 - 20000) = 500 miles higher than before.
Write two numbers that multiply to the value on top and add to the value on bottom. -60−60 -4−4 \times× ++
Answer:
The two numbers are 6 and -10
Step-by-step explanation:
Given
[tex]Product = -60[/tex]
[tex]Sum =-4[/tex]
Required
Two numbers that satisfy the above
Let the two numbers be x and y.
So:
[tex]x * y = -60[/tex]
[tex]x + y = -4[/tex]
Make x the subject
[tex]x = -4 - y[/tex]
Substitute [tex]x = -4 - y[/tex] in [tex]x * y = -60[/tex]
[tex](-4 -y) * y = -60[/tex]
Open bracket
[tex]-4y -y^2 = -60[/tex]
Rewrite as:
[tex]y^2 + 4y - 60 = 0[/tex]
Split
[tex]y^2 + 10y - 6y - 60 = 0[/tex]
Factorize
[tex]y(y + 10) - 6(y + 10) = 0[/tex]
Factor out y + 10
[tex](y - 6) (y + 10) = 0[/tex]
Solve for y
[tex]y -6=0\ or\ y+10=0[/tex]
[tex]y =6\ or\ y=-10[/tex]
Recall that:
[tex]x = -4 - y[/tex]
So:
[tex]x = -4-6= -10[/tex]
or
[tex]x = -4--10= 6[/tex]
So:
[tex]y =6\ or\ y=-10[/tex]
[tex]x = -10\ or\ x =6[/tex]
The two numbers are 6 and -10
A line has a slope of 8 and a y-intercept of 5. What is its equation in slope -intercept form?
Answer:
y = 8x + 5
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 8 and c = 5
y = 8x + 5 ← equation of line

Answer:
Let's define the cost of the cheaper game as X, and the cost of the pricer game as Y.
The total cost of both games is:
X + Y
We know that both games cost just above AED 80
Then:
X + Y > AED 80
From this, we want to prove that at least one of the games costed more than AED 40.
Now let's play with the possible prices of X, there are two possible cases:
X is larger than AED 40
X is equal to or smaller than AED 40.
If X is more than AED 40, then we have a game that costed more than AED 40.
If X is less than or equal to AED 40, then:
X ≥ AED 40
Now let's take the maximum value of X in this scenario, this is:
X = AED 40
Replacing this in the first inequality, we get:
X + Y > AED 80
Replacing the value of X we get:
AED 40 + Y > AED 80
Y > AED 80 - AED 40
Y > AED 40
So when X is equal or smaller than AED 40, the value of Y is larger than AED 40.
So we proven that in all the possible cases, at least one of the two games costs more than AED 40.

What is translation?A translation in mathematics does not turn a shape; instead, it moves it left, right, up, or down. They are congruent if the translated shapes (or the image) seem to be the same size as the original shapes. They've simply shifted in one or more directions.
Given that the functions are f(x) = x³ and g(x) = ( x + 4 )³. The translation of the function will be at 4 units to the left.
When the functions are plotted on the graph the translation is seen to the left of the origin at the coordinate (-4,0).

Here is a diagram and its corresponding equation. Find the solution to the equation and explain your reasoning 38 x+7 x+7 x+7 x+7 4(x + 7) = 38
Answer:
x = (-158)/87
Step-by-step explanation:
Solve for x:
38 x + 7 x + 7 x + 7 x + 7×4 (x + 7) = 38
Hint: | Multiply 7 and 4 together.
7×4 = 28:
38 x + 7 x + 7 x + 7 x + 28 (x + 7) = 38
Hint: | Group like terms in 38 x + 7 x + 7 x + 7 x + 28 (x + 7).
Grouping like terms, 38 x + 7 x + 7 x + 7 x + 28 (x + 7) = 28 (x + 7) + (38 x + 7 x + 7 x + 7 x):
28 (x + 7) + (38 x + 7 x + 7 x + 7 x) = 38
Hint: | Add like terms in 38 x + 7 x + 7 x + 7 x.
38 x + 7 x + 7 x + 7 x = 59 x:
28 (x + 7) + 59 x = 38
Hint: | Distribute 28 over x + 7.
28 (x + 7) = 28 x + 196:
28 x + 196 + 59 x = 38
Hint: | Add like terms in 59 x + 28 x + 196.
28 x + 59 x = 87 x:
87 x + 196 = 38
Hint: | Isolate terms with x to the left hand side.
Subtract 196 from both sides:
87 x + (196 - 196) = 38 - 196
Hint: | Look for the difference of two identical terms.
196 - 196 = 0:
87 x = 38 - 196
Hint: | Evaluate 38 - 196.
38 - 196 = -158:
87 x = -158
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 87 x = -158 by 87:
(87 x)/87 = (-158)/87
Hint: | Any nonzero number divided by itself is one.
87/87 = 1:
Answer: x = (-158)/87
The mean of Tom’s scores on 5 tests was 77.4%. The scores on his first four tests were 88, 77, 70, and 72. What was Tom’s score on his fifth test?
Answer:
88%
Step-by-step explanation:
First we multiply the mean by 5.
77.4 x 5 = 387
Then we add all of the test scores.
88 + 77 + 70 + 72 = 299
We subtract the total of the scores from 387, which we got from mulitplying the mean by 5.
387 - 299 = 88
Therefore, Tom's score on his fifth test was an 88%.
Hope this helps!
