Let one be x

  • Other one is x-10

ATQ

\\ \sf \longmapsto x+x-10=90

\\ \sf \longmapsto 2x-10=90

\\ \sf \longmapsto 2x=90+10

\\ \sf \longmapsto 2x=100

\\ \sf \longmapsto x=\dfrac{100}{2}

\\ \sf \longmapsto x=50

\\ \sf \longmapsto x-10=50-10=40

Answer:

C

Step-by-step explanation:

The vertex form for a parabola is a(x-h)^2 + k, where h is the x coordinate of the vertex and k is the y coordinate. a represents the amount that the graph has been "squeezed". Therefore, since the coordinates of the vertex of this parabola are (2,4), and it is "squeezed" by a factor of 2, the correct answer is C. Hope this helps!

Which coordinate pair fits the set of coordinates {(0, 4), (-2, 1), (-4, -2)} defined by a linearfunction?
dedylja [7]

Answer:

y = 1.5x + 4

Step-by-step explanation:

Slope = (y2-y2)/(x2-x1)

= (1-4)/(-2-0) = -3/-2 = 3/2

y = (3/2)x + c

When x=0, y=4 (y-intercept is 4)

y = (3/2)x + 4

y = 1.5x + 4

John often speed while driving to school in order to arrive on time. The probability that he will speed to school is 0.75. If th
BartSMP [9]

Answer:

0.33

Step-by-step explanation:

Given the following :

P(speeding) = p(s) = 0.75

P(being stopped) = p(t)

P(speeding and gets stopped) = p(s n t) = 0.25

Find the probability that he is stopped, given that he is speeding is written as P(t | s) ;

P(t | s) = p(s n t) / p(s)

P(s n t) = 0.25

P(s) = 0.75

Hence,

P(t | s) = 0.25 / 0.75

P(t | s) = 0.33
