Answer:

one solution : (-2 ; -7)

Step-by-step explanation:

hello :

x - y = 5 ....(*)

- 3 x + y = - 1 ....(**)

by (*) : y=x-5

by(**) : y = 3x-1

3x-1 = x -5

3x-x=-5+1

2x= -4

x= -2

but : y = x-5    so : y= -2-5=-7

one solution : (-2 ; -7)

Answer:

x = 39

Step-by-step explanation:

there is a theorem that states that the midsegment in a trapezoid is equal to the sum of the bases divided by two

so, (36 + 42)/2 = x

36 + 42 = 78

78/2 = 39

Answer:

In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse (the side opposite the right angle) is equal to the sum of the areas of the squares on the other two sides. This theorem can be written as an equation relating the lengths of the sides a, b and c, often called the "Pythagorean equation": a²+b²=c², where c represents the length of the hypotenuse and a and b the lengths of the triangle's other two sides.

When x is substituted with -2 in the given expression, the value of the expression is 1.

Given the expression and the value of x, we can substitute x with -2 and evaluate the expression.  For example, if the expression is x² + 2x - 3 and you want to find the value when x = -2, then you'd substitute x = -2 into the expression giving (-2)² + 2*(-2) - 3 = 4 - 4 - 3 = -3. Substituting values in, simplifying, and solving is the general process to follow when coming across this kind of problem in quadratic equations or other areas of Algebra.

Let's say the expression is 2x + 5. Substituting x with -2, we get:

2*(-2) + 5 = -4 + 5 = 1

Therefore, the value of the expression when x = -2 is 1.

The difference between the distances from New York to Hawaii than his trip from Hawaii to Texas is 1383 miles.

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, Mr. Price flew 4,908 miles from New York to Hawaii. He then flew 3,525 miles from Hawaii to Texas.

Therefore, The difference between the distances from New York to Hawaii than his trip from Hawaii to Texas is,

= (4908 - 3525)  miles.

= 1383 miles.

Mr. Price's trip from New York to Hawaii was 1,383 miles longer than his trip from Hawaii to Texas.

Calculating the Distance Difference :

To find out how much farther Mr. Price's trip from New York to Hawaii was compared to his trip from Hawaii to Texas, we need to subtract the distance from Hawaii to Texas from the distance from New York to Hawaii.

Now, let's subtract the two distances:
4,908 miles - 3,525 miles = 1,383 miles

Therefore, Mr. Price's trip from New York to Hawaii was 1,383 miles longer than his trip from Hawaii to Texas.

Step-by-step explanation:

The slope is found by

m = (y2-y1)/(x2-x1)

    = (3-1)(1--2)

     = (3-1)/(1+2)

     =2/3

We can use the points (-2, 1) and (1, 3) to solve.

Slope formula: y2-y1/x2-x1

= 3-1/1-(-2)

Answer:

A. 25 miles per gallon

B. 225 miles

Step-by-step explanation:

Part A is asking for an average - how many miles does the car get out of each gallon. This can be found by dividing the total change in miles by the total change in gallons.

In this case, the changes in each are:

250 miles

10 gallons

250/10 is 25. Thus there are 25 miles per gallon.

Part B is asking for how much can you get with 9 gallons, meaning how many miles corresponds to 9 on the graph. The graph is at 225 miles at the x=9 mark, and thus the answer for part be is 225.

Answer:

64

Step-by-step explanation:

You open up the (3x+5)^2 and get:

9x^2 + 30x + 25

So...

a+b+c = 64

OR

You add the coefficient(s) and the constant together in the parentheses and get:

(3x+5)^2 --> (8)^2

So you square the 8 and get:
