In a survey, 200 people were polled about whether they preferred spending their free time playing sports, watching a movie, or r

Rama09 [41]

A) 25% of males preferred playing sports.

Explanation) .25 is the same is 25%.

B) 25% of the people surveyed preferred reading a book.

Explanation) You have to add up how many males and females rather
to read a book. It's .10 + .15 = 25%.

C) 70 females were surveyed out of 200 people.

Explanation) Add up .15 + .5 + .15 to get .35. Put .35 multiplied by 200 to get 70.

What is the solution of the linear system of equations? please help

Mademuasel [1]

Sub for each other since both equals y
2x-3=y=2x+5
2x-3=2x+5
minus 2x oth sides
-3=5
false

no solution
(we can see that since slopes are same and y intercepts are differnt, the lines are paralell and therfor never intersect)

D. No solution

Bob had 20 apples, if he gave away 14 how many would he have left?

vodka [1.7K]

6, Bob will have 6 apples after he gives 14 away.

To solve this problem, we must first understand what it is asking. Since Bob is giving away apples, he is subtracting them from his total amount. So, now we do the subtraction.

20 - 14 = 6, so Bob will have 6 apples after he gives 14 away.

The shape of the graph of quadratic functions is the shape of a parabola.

The steps for drawing a graph of the function f(x) = 2·(x + 4)² - 3 arranged in the correct order are;

(a) Plot the vertex (-4, -3)

(b) Apply the 2·x² pattern, from the vertex go right 1 up 2 and plot (-3, -1)

(c) Apply the 2·x² pattern again, from the vertex go right 2 up 8 and plot (-2, 5)

(d) Apply the 2·x² pattern a 3rd time, from the vertex go right 3 up 18 and plot (-1, 15)

(e) Draw the axis of symmetry x = -4

(f) Reflect the points over the axis of symmetry and plot (-5, -1), (-6, 5), and (-7, 15)

(g) Draw a U shaped parabola.

Reasons:

The given function is; f(x) = 2·(x + 4)² - 3

The function is given in the vertex form; f(x) = a·(x - h)² + k

Therefore, the vertex, (h, k) = (-4, -3)

Step (a);

The vertex can be plotted on the graph

Plot the vertex (-4, -3)

Step (b);

Given that the quadratic term is 2·x², the pattern that can be used for the points from the vertex is therefore, 2·x²

From the vertex (-4, -3) apply the 2·x² pattern by going to the right 1 unit and up 2 × 1² = 2 units to get the point (-4 + 1, -3 + 2) = (-3. -1)

Apply the 2·x² pattern, from the vertex go right 1 up 2 and plot (-3, -1)

Step (c);

To get the next point, the 2·x² pattern is applied with x = 2, to the vertex to get; (-4 + 2, -3 + (2×2²)) = (-2, 5)

Apply the 2·x² pattern again, from the vertex go right 2 up 8 and plot (-2, 5)

Step (d);

A third point on the graph relative to the vertex is obtained again by applying the 2·x² pattern again to the vertex with x = 3, to get;

(-4 + 3, -3 + (2 × 3²)) = (-1, 15)

Apply the 2·x² pattern a 3rd time, from the vertex go right 3 up 18 and plot (-1, 15)

Step (e);

The axis of symmetry can be drawn with a vertical line passing through the vertex, which is the line, x = -4

The line x = -4 can be drawn on the graph next

Draw the axis of symmetry x = -4

Step (f);

The points obtained relative to the vertex (-3, -1), (-2, 5), (-1, 15) can reflected about the axis of symmetry x = -4, to get;

(-3, -1) $\underrightarrow {R_{(x = -4)}}$ (-5, -1)

(-2, 5) $\underrightarrow {R_{(x = -4)}}$ (-7, 5)

(-1, 15) $\underrightarrow {R_{(x = -4)}}$ (-7, 15)

Reflect the points over the axis of symmetry and plot (-5, -1), (-6, 5), and (-7, 15)

Step (g);

The parabola that is U shaped can be drawn from the points plotted in the steps above.
