Answer:

x=50 ∠BCX=65

Step-by-step explanation:

The angles is a triangle add up to 180 so

70+45+∠BCX=180 so

115+∠BCX=180 (subtract 115 from both sides)

∠BCX=65

A line adds up to 180

so 2x+15+65=180

so 2x+80=180 (subtract 80 from both sides)

2x=100 (divide by 2)

x=50

Which of the following is the equation of the quadratic function below?
exis [7]

Answer:

A. y = x² - 9x + 18

Step-by-step explanation:

The key thing to look for in this graph is the <u>y-intercept</u> (where the graph will hit the y-axis).

We can't see exactly where y-intercept is, but we know it is a positive number.

In a standard form quadratic equation:

<em>y = ax² + bx + <u>c</u></em>

'<em>c</em>' tells you what the y-intercept is.

The choices with positive y-intercept are <u>A</u> and <u>B</u>.

Again, we can't see exactly where y-intercept is, but we know it is not 1.

y = x² - 9x + 18

has a positive y-intercept that is not 1,

thus the answer is A.

list M and n are the zeros of the polynomial 3x square + 11 x minus 4 then find the value of m divided n plus n dividedm​
Vaselesa [24]

Answer:

Step-by-step explanation:

3x²+11x-4

when splitting the middle term

it becomes

3x²+12x-1x-4

=3x(x+4)-1(x+4)

(3x-1)(x+4)

either 3x-1=0 then x=1/3

or x+4=0 then x= -4

m=1/3

n=-4

therefore

value of m divided n plus n dividedm​=1.25

hope this helps plzz mar me brainliest
