Answer: 540

Step-by-step explanation:

2.5 x 3 is 7, so if he travels at the same rate, you must increase the miles by the same amount. So in this case its 180 x 3, which is 540.

8 Line in the xy-plane contains points from each of Quadrants II, III, and IV, but no points from Quadrant I. Which of the follo

iren2701 [21]

Answer:

The correct option is D.

Step-by-step explanation:

The slope of a line is the change in y with respect to x.

$m=\frac{y_2-y_1}{x_2-x_1}$

If the slope of a line is undefined it means it is a vertical line and a vertical line can not passes through three quadrants. So, option A is incorrect.

If the slope of a line is 0 it means it is a horizontal line and a horizontal line can not passes through three quadrants. So, option B is incorrect.

If the slope of a line is positive it means the value of y increases as x increases.

Since it is an increasing line, therefore after a certain period both x and y will positive. It means the line will passes through first quadrant. So, option C is incorrect.

If the slope of a line is negative it means the value of y decreases as x increases. It can passes through each of Quadrants II, III, and IV.

Therefore the correct option is D.

Two positive integers have a product of 176. One integer is 5 less than the other integer. Which equation can be used to find th

faust18 [17]

$xy=176$
$y=x-5$

$\implies x(x-5)=176\implies x^2-5x-176=(x+11)(x-16)=0$
$\implies x=-11, x=16$

Since $x>0$ , we take $x=16$ , which means $y=16-5=11$ .

What is the vertex form, f(x) = a(x - h)2-k, for a parabola that passes through the point (2,8) and has (1,0) as its

Novay_Z [31]

Answer:

Step-by-step explanation:

hello :

f(x) = a(x - h)²-k ....vertex form when the vertex is : (h,k)

h=1 and k=0 so : f(x) = a(x-1)²

a parabola that passes through the point (2,8) : f(2)=8

a(2-1)² =8

a= 8

f(x) = 8(x-1)²= 8(x²-2x+1)

f(x) 8x²-16x+8 .....standard form
