18w2(squared) - w - 39​

Answers

Answer 1

Answer:

w = 1.5 and -1.44

Step-by-step explanation:

Given the quadratic equation 18w^2 - w - 39

Using the general formuls

w = 1 ±√1²-4(18)(-39)/2(18)

w =1 ±√1+2808/36

w =1 ±√2809/36

w = 1+53/36 and 1-53/36

w  = 54/36 and -52/36

w = 1.5 and -1.44

Answer:

Angle ABF is 120°.

Step-by-step explanation:

Vertical angles are used to get the measure of angle ABG (3x) and FBE (2x) and all of those added together are 180. Then you use PEMDAS to get x. Then you find ABF by multiplying 3 by 30 (what you get when you use PEMDAS to find x) then you add 30 to that and you get 120.

what is 8u+17=17 what is u = to

Answers

Answer:

[tex]8u+ 17 = 17 \\ 8u = 17 - 17 \\ 8u = 0\\ u = \frac{0}{8} \\ \boxed{u = 0}[/tex]

u=0 is the right answer.

you would try to isolate u first. to do this, subtract 17 from each side. you should have 8u=0. then, divide 8 from each side. you should have u=0.

A taxi charges a flat fee of $3.00, plus an additional $1.25 per mile. Antonio can spend no more than $18. Choose the inequality that represents the number of miles he can ride, an describes the solution set.

Answers

Answer: 1.25m + 3 ≤ 18; Antonio can ride 12 or fewer miles

Step-by-step explanation: so you can break down the answer choices and only have a and b left because no more than means this sign: ≤

and 1.25 is the cost for each mile so your multiplying m and 1.25 and then you add that with 3.

First off, a triangle will be 180 all together, so, x + 59 + x + 51 = 180, 59 + 51 is 110, x + x is 2x, 180 - 110 is 70 so you have 2x = 70, now divide both sides by two, The left will cancel out to x and the other will be 35, x = 35, now you are looking for angle a, in order to find this, you have to plug in your X, so 51+35 is 86, that should be your answer, I hope this helps!

$213 ski jacket with a 30% discount and a 6% tax

Answers

$158.046

Take the discount off first, 213*.70=149.10, then multiply 149.10*1.06= $158.046

158.04$.

What is discount?

A discount is a decrease in the cost of a commodity or service. If the item is broken, you can ask the manager for a discount.

Given the Written price of the ski jacket is 213$ on that there is a discount of 30% and 6% of tax. Hence,

discounted price of jacket = 213 (1- 30%)

discounted price of jacket = 149 approx.

Total price of the jacket after-tax = 149 (1 + 6%)

The total price of the jacket after-tax = 158.04$

Therefore, the price of a $213 ski jacket with a 30% discount and a 6% tax is 158.04$.

Describe how each graph is obtained from the graph of y= f(x).

(a) y = f(x – 2)

Can somebody help telling what does it mean? what does it want us to do? ​

Answers

Answer:

see explanation

Step-by-step explanation:

Give the graph of y = f(x) then y = f(x + a) represents a horizontal translation of y = f(x)

• If x > 0 then a shift to the left of a units

• If x < 0 then a shift to the right of a units

Thus

y = f(x - 2) is the graph of y = f(x) translated 2 units right

The side lengths of a triangle are 5,√3,√28. Is the triangle a right triangle? How would I solve this?

Answers

I’m not good at explaining but I’ll try.

Legs: 5, √3. Hypotenuse: √28

So your legs are: a and b, and ur hypotenuse is c

a^2+b^2=c^2
Which means

5^2+√3 has to equal to √28^2.

Let’s solve it

5^2+√3^2= √28^2

= 25+3=28

28=28

So that is a right triangle.


First to Answer:

Here's all that you really can do with solving that

Which expression rrepresents the length of QR ?


helpppp

Answers

Answer:

QR = 4x - 6

Step-by-step explanation:

A triangle is a polygon that has three sides and three angles. There are different types of triangles such as equilateral triangle, isosceles triangle, scalene triangle, right angled triangle.

The perimeter of a triangle is a measure of the length of the sides. It is the sum of all the length of the three sides of the triangle.

From the question:

Perimeter of triangle PQR = PQ + PR + QR

But PR = 3x - 1, PQ = x + 1, Perimeter of PQR = 8x - 6.

Therefore substituting gives:

8x - 6 = (x + 1) + (3x - 1) + QR

8x - 6 = (x + 3x + 1 - 1) + QR

8x - 6 = 4x + QR

QR = (8x - 6) - 4x

QR = 4x - 6
