Which is equivalent to 4y-2x=16

Answers

Answer 1

Answer: x-intercept. y-intercept
4*0-2x=16. 4y-2*0=16
-2x+0=16. 4y-0=16
-0. -0. +0 +0
-2x. /-2 = 16/-2 4y/4 =16/4
x = -8. y = 4
(-8,0) (0,4)

Find 3 consecutive odd integers whose sum is 225, explain please

Answers

3 odd integers have a property that they average up to the middle large one. Let's say we have 3, 5, and 7. 3 is 2 less than 5 and 7 is 2 more than 5. so when you add them it equals 2 times 5.
After we know that, the sum of 3 odd integers is just 3 times the middle number. ex. 3+5+7 = 3 times 5 = 15
Then we know the some number times three = 225. we find out that the middle number is 75, so the other two are 73 and 77

If X=3, What is the area of a triangle with sides, 6x ,7x, and 21x? A.117 in² B.378 in² C.189 in² D. 58.5 in²

Answers

Answer:

The given sides does not form a triangle

Step-by-step explanation:

The given sides does not form a triangle

We know the triangle property which states that the sum of any two sides of the triangle should be greater than the third side.

Here given th esides of the triangle are 6x,7x,21x

6x+7x=13x < 21x

for any value of x the above equation does not satisfy.

How do you solve 4x^2-12x=7 algebraically

Answers

(if you don't wanna read all this the answer is at the bottom btw)

move the 7 over to equate the equation to 0

4x^2 - 12x -7 = 0

(ok now you have a (4), b (-12), and c (-7) here you can either use the quadratic formula to solve it or factor the equation)

to factor it, you have to multiply a and c (4*-7 = -28) and find two numbers that multiply to -28 and add to -12

the numbers are -14 and 2. sub those into the equation in place of b

4x^2 + 2x - 14x - 7 = 0

find the lcd of the first two terms and the last two terms to factor them

2x(2x + 1) - 7(2x+1) = 0
(2x -7) (2x+1) = 0
(x-7/2)(x+1/2) = 0

to find the two x values you need to find what values make the equation equal 0 on both sides.

so x is 7/2 or -1/2

Solve each equation by factoring.
