Answer:

<ABC = 80°

Step-by-step explanation:

find x first

<ABC = 1/2[(9x - 7) +(5x + 13)]

8x - 8 = 1/2(9x - 7 + 5x + 13)

16x - 16 = 14x + 6

2x = 22

x = 11

Plug in x = 11 into 8x - 8

<ABC = 8(11) - 8

<ABC = 88 - 8

<ABC = 80°

Only t circled ones somebody plz help I am gonna get a 0 plz help I will give you brainleist

Vikki [24]

Step-by-step explanation:

1) A number m is at least four

m ≥ 4 ['at least' = ≥ symbol]

2) 4x ≤ 20x; x=2

4(2) ≤ 20(2)

8 ≤ 40

[Im not sure if this is a solution or and inequality :/ ]

3) x < 5

--> On the line, draw the number 0, and the number five. 'x < 5' also means 'x is less that five.' So, draw a dot over the line before 5, and make an arrow going to the left of the page,

<-----------------------------------o 5

<---|---|---|---|---|---|---|---|---|---|---|---|---|---|--->

Hopefully this helps! :)

Write a quadratic function in standard form with zeros 1 and -10

Licemer1 [7]

Answer:

f(x)=x^2+9x-10

Step-by-step explanation:

Standard Form of Quadratic Function

The standard form of a quadratic function is:

$f(x)=ax^2+bx+c$

where a,b, and c are constants.

The factored form of a quadratic equation is:

$f(x)=a(x-\alpha)(x-\beta)$

Where $\alpha$ and $\beta$ are the roots or zeros of f, and a is constant.

We know the zeros of the function are 1 and -10. The function is:

$f(x)=a(x-1)(x-(-10))$

$f(x)=a(x-1)(x+10)$

Operating:

$f(x)=a(x^2+10x-x-10)$

Joining like terms:

$f(x)=a(x^2+9x-10)$

Since we are not given any more restrictions, we can choose the value of a=1, thus. the required function is:

$\boxed{f(x)=x^2+9x-10}$

A ski resort has 18 inches of snow on the ground. The snow is falling at a rate of 4 inches per hour. which type of functions be

faust18 [17]

Answer:

Linear Function

$y=4x+18$

Step-by-step explanation:

Let

x----> the time in hours

y----> the total inches of snow on the ground

we know that

The function that best model this situation is the linear function

$y=mx+b$

In this problem

$m=4\frac{in}{h}$

$b=18\ in$ ----> the y-intercept

substitute

$y=4x+18$
