Combine like terms to simplify the expression 3X + 5 - X + 1

Answer:

Step-by-step explanation:

hello :

given the line  :  5x – 2y = -6

the answer is : 2x + 5y = -10  because :

1) this line passes through then point (5 ,-4) : 2(5)+5(-4)=-10....right

2)  the slope of   the given line is: 5/2   because 5x-2y=-6  equivalent to ;

2y =5x+6   so : y = (5/2)x+3

On the other hand :  2x + 5y = -10 equivalent to : 5y =-2x-10

y = (-2/5)-2  when the slope is : -2/5

the condition for the perpendicularity is : product two slope is : - 1

(5/2)(-2/5) =-1

Answer:

2/3

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)

= 2/3

Best of Luck!

Answer:

k=11

Step-by-step explanation:

3(k - 6) = 15

Divide each side by 3

3/3(k - 6) = 15/3

k - 6 = 5

Add 6 to each side

k-6+6 = 5+6

k = 11

Answer:

k=11

Step-by-step explanation:

3(k-6) = 15

k-6 = 15/3

k-6=5

k=5+6

k=11

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.

Step-by-step explanation:

The required, adjacent angle to DFE is angle BFC. Option D is correct.

Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

Angle BFC is next to angle DFE, and they share a common side, which is line segment EF. Therefore, we can stretch this statement as follows:

"When looking at the angle DFE and moving clockwise around the vertex F, the next angle encountered is angle BFC, which is adjacent to angle DFE and shares the side EF with it."

This restatement clarifies the location and relationship of angle BFC with respect to angle DFE.

Thus, the required, adjacent angle DFE is angle BFC. Option D is correct.

To determine the amount of cheese used per pizza, divide the total amount of cheese (4.375 pounds) by the number of pizzas (50), which equals 0.0875 pounds of cheese per pizza.

Explanation:

To find out how many pounds of cheese are used per pizza, we calculate the cheese usage rate by dividing the total pounds of cheese by the number of pizzas. The given information tells us that 4.375 pounds of cheese are used for every 50 pizzas. To find the amount of cheese used per pizza, we divide 4.375 pounds by 50.

4.375 pounds ÷ 50 pizzas = 0.0875 pounds per pizza

Thus, the restaurant uses 0.0875 pounds of cheese for each pizza made.

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.

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.
