$7(-2x +4) = -4x \\\\\implies -14x + 28 = -4x \\\\\implies -14x +4x = -28\\\\\implies -10x = -28\\\\\implies x = \dfrac{-28}{-10} = \dfrac{14}5$

Answer: x = 14/5

Explanation:

-14x + 28 = -4x
-14x = -4x - 28
-14x + 4x = -28
-10x = -28
X = 14/5

Which expression represents 9 less than a number?

My name is Ann [436]

Answer:

x-9

Step-by-step explanation:

"Less than" switches the way of the expression.

If the "less than" was not there it would have been:

9-x

"Less" means subtract so you would subtract x from 9.

Hope this helped!

What is the value of sin0 in the diagram below?

Tasya [4]

Answer:

The answer to your question is: 24/25

Step-by-step explanation:

Remember that sinФ = opposite leg / hypotenuse

Opposite leg = 24/25

Hypotenuse = 1

then sin Ф = (24/25) / 1

sin Ф = 24/25

Find the x-intercept(s) of y = 2x2 - 3x - 5.<br> A) -5 <br> B) 2 1/2, -1<br> C) 3, -5 <br> D) 5, -1

Alexus [3.1K]

Answer:

$\large\boxed{B)\ 2\frac{1}{2},\ -1}$

Step-by-step explanation:

x-intercepts are for y = 0.

We have the equation:

$y=2x^2-3x-5$

Therefore

$2x^2-3x-5=0\\\\2x^2+2x-5x-5=0\\\\2x(x+1)-5(x+1)=0\\\\(x+1)(2x-5)+0\iff x+1=0\ \vee\ 2x-5=0\\\\x+1=0\qquad\text{subtract 1 from both sides}\\\boxed{x=-1}\\\\2x-5=0\qquad\text{add 5 to both sides}\\2x=5\qquad\text{divide both sides by 2}\\\boxed{x=2\frac{1}{2}}$
