Answer:

y = -8

Step-by-step explanation:

Next time, please share the answer choices!

Going from (–4, –8) to (-2, -8), x increases by 2, but y stays the same. Thus, the line is horizontal and must pass through y = -8.

In other words, the correct representation of this line is y = -8.

Jordan has 10 friends in the school band. The number of his friends who play the saxophone is shown in the grid. Use the grid to

slava [35]

Jordan needs 10 copies of the squares to have 100
With that, there will be 30 shades squares
So 30% of Jordan’s friends play sax

What is the value of x? There is isosceles triangle. The measure of angle which is between two congruent sides is (6x+10⁰). The

max2010maxim [7]

<h3><u>Answer</u><u>:</u><u>-</u></h3>

x=17

<h3><u>step-by</u><u>-</u><u>step</u><u> </u><u>Explanation</u><u>:</u><u>-</u></h3>

${\boxed{\quad\:\mapsto\rm Firstly\:Let's\:understand\:the\:concept:-}}$

<h3 />

This is a isosceles triangle. As it is a triangle we can apply sum theory. we have to take the sum of given unknown polynomials as 180° .Then by solving it we can find the value of x.

<h3><u>Solution</u><u>:</u><u>-</u></h3>

Given angles

(6x+10°)
(x+17°)
(4x-34)°

According to sum theory

${\boxed{\sf The \:sum\:of\:angles=180°}}$

Substitute the values

$\qquad \quad{:}\longmapsto\tt (6x+10)+(x+17)+(4x-34)=180$

Remove brackets

$\qquad \quad{:}\longmapsto\tt 6x+10+x+17+4x-34=180$

Together like polynomials and constants

$\qquad \quad{:}\longmapsto\tt 6x+x+4x+10+17-34=180$

$\qquad \quad{:}\longmapsto\tt 11x-7=180$

Interchange sides

$\qquad \quad{:}\longmapsto\tt 11x=180+7$

$\qquad \quad{:}\longmapsto\tt 11x=187$

$\qquad \quad{:}\longmapsto\tt x=\cancel{\dfrac{187}{11}}$

Simplify

$\qquad \quad{:}\longmapsto\tt x=17$

$\therefore\sf The \:value\:of\:x\;is\:17.$

Jeffrey is asked to graph f(x)=x^2 - 6x + 5. Below is his graph. Is his graph correct or incorrect?

jeka94

Answer:

His graph is incorrect, because, Jeffrey drew it with vertex (4 , -4) and x-intercepts (2 , 0) and (5 , 0), but the vertex is (3 , -4) and x-intercepts are (1 , 0) , (5 , 0)

Step-by-step explanation:

The quadratic function y = ax² + bx + c is represented graphically by a parabola

The parabola has a vertex point, the point which divides the parabola into two congruent parts
The parabola is opened downward if the leading coefficient a is negative, then its vertex is maximum
The coordinates of the vertex point are (h , k), where h = $-\frac{b}{2a}$ and k is the value of y at x = h
The x-intercepts are the values of x at y = 0

∵ The quadratic is f(x) = x² - 6x + 5

∴ a = 1 , b = -6 and c = 5

∵ The leading coefficient a is positive

∴ The graph of f(x) is a parabola oped upward

∴ <em>The parabola has a minimum vertex</em>

The vertx point of the parabola is (h , k)

∵ h = $-\frac{b}{2a}$

∴ h = $-\frac{-6}{2(1)}$

∴ h = 3

- To find k substitute x by 3 in f(x)

∵ f(3) = (3)² - 6(3) + 5 = 9 - 18 + 5

∴ f(3) = -4

∵ k = f(3)

∴ k = -4

That means the coordinates of the vertex of the parabola are (3 , -4)

The x-intercepts means values of x at f(x) = 0

∵ x² - 6x + 5 = 0

- Factorize it into two binomial factors

∵ x² = (x)(x)

∵ 5 = (-1)(-5)

∵ (x)(-1) + (x)(-5) = -x + -5x = -6x

- That means the factors are (x - 1) and (x - 5)

∴ The factors of x² - 6x + 5 are (x - 1) and (x - 5)

∴ (x - 1)(x - 5) = 0

Equate each factor by 0 to find the value of x

∵ x - 1 = 0

- add 1 to both sides

∴ x = 1

∵ x - 5 = 0

- add 5 to both sides

∴ x = 5

∴ The x-intercepts are (1 , 0) and (5 , 0)

That means the parabola intersects the x-axis ate points (1 , 0) and (5 , 0)

Jeffrey drew the graph with vertex (4 , -4) and x-intercepts (2 , 0) and (5 , 0), then his graph is incorrect
