If f(x) = 2x, which of the following shows the graph of f(x) = 2(x) + 2?

Answers

Answer: the first graph

Step-by-step explanation:

The intersection of the graph of the function with the y-axis gives the y-intercept of that function. The correct option is A.

What is the y-intercept of a function?

The intersection of the graph of the function with the y-axis gives the y-intercept of that function. The y-intercept is the value of y on the y-axis at which the considered function intersects it.

Assume that we've got: y = f(x)

At the y-axis, we've got x = 0, so putting it will give us the y-intercept.

Thus, y-intercept of y = f(x) is y = f(0)

Given f(x)=2, therefore, the graph will have a y-intercept as 0.

But when the value of f(x) = 2(x) + 2, then the graph of the function will have the y-intercept at 2.

Hence, the correct option is A.

Given ABCD what is the value of y? ​

Answers

Answer:

x=7

y=5

Step-by-step explanation:

quadrilaterals have 360 degrees, and their opposite angles are equal

15x+5=16x-2

7=x

(plug back in to find angle)

15(7)+5=110

that angle, plus opposite angle, equals 110.

360-220=140

140/2=70

now we know the value of other unsolved angle

70=12y+10

60=12y

5=y

May I plz get some help plz

Answers

Step-by-step explanation:

5x +10° + 58° = 11x + 2°( Exterior angle of a triangle is equal to the sum of two opposite interior angles)

5x + 68° = 11x + 2°

11x - 5x = 68° - 2°

6x = 66°

x = 66° / 6

Therefore x = 11°

Acela Express, the fastest train between Washington D.C and Boston covers a distance of 455 miles in 7 hours. How many miles will the train travel in 4 hours?

Answers

Answer:

What is the image point of (−2,5) after a translation left 5 units and up 3 units?

Answers

Answer:

(-7,8)

Step-by-step explanation:

The given point (x,y)=(-2,5)

Assuming that right and up directions are positive, so left and down directions are negative.

So, after a translation left 5 units and up 3 units, the image point = (x-5, y+3)

=(-2-5, 5+3)= (-7,8)

Hence, the image point is (-7,8).
