Which of the following coordinates is a solution to the linear equation?
Dima020 [189]
Right this is pretty simple all you do is sub the points to the equation given.
So first try the first point (2,-1) in y=-3x+7
==> -1=-3(2)+7
==>-1=1 this is not equal therefore not the right points

Then try (1,10)
==>10=-3(1)+7
==>10=4 this is incorrect therefore not the right points

Next try (3,-2)
==>-2=-3(3)+7
==>-2=-2 this is equal therefore this is the coordinates to the linear equation.

Finally try the last points to make sure you are correct.
==> -8=-3(-5)+7
==>-8=22 this is incorrect also.

Therefore the only coordinates that satisfies the equation is (3,-2)

Solve for 2x^2-4x+5=6
Softa [21]
To solve for a variable, you need to get it (x) by itself.

2x² - 4x + 5 = 6   Subtract 6 from both sides
2x² - 4x - 1 = 0   Plug this into the Quadratic Formula

a = 2 , b = -4 , c = -1
x = \frac{-b \pm  \sqrt{b^2 - 4ac} }{2a}   Plug in your values
x = \frac{-(-4) \pm \sqrt{(-4)^2 - 4(2)(-1)} }{2(2)}   Simplify
x = \frac{4 \pm \sqrt{16 + 8} }{4}   Simplify
x = \frac{4 \pm 2\sqrt{6} }{4}   Simplify by removing a 2 from every term
x = \frac{2 \pm \sqrt{6} }{2}   Simplify by taking the fraction apart
x = \frac{2}{2}  \pm  \frac{ \sqrt{6} }{2}   Change \frac{2}{2} to 1
x = 1 \pm  \frac{ \sqrt{6} }{2}   Simplify \frac{ \sqrt{6} }{2} to \sqrt{ \frac{3}{2} }
x = 1 \pm \sqrt{ \frac{3}{2} }

Children of mothers who smoked during pregnancy scored nine points lower on intelligence tests at ages three and four than child
eduard

Answer:

All of the options apply.

Step-by-step explanation:

In the example given in the question, it is stated that mothers' smoking during pregnancy can affect childs' IQ and can cause lower scores on test.

All of the given options can be given as evidence for the link between smoking and lower IQ. The diet especially throughout childhood has significant effect on the development of the brain and the prefrontal cortex.

The psychological condition that the child is in, the environment in the house that he/she grows up in affects the IQ and the EQ.

The IQ can be affected by outside factors but it also has a relation with the genes that the child takes from his/her parents.

The socioeconomic status of the mother can affect the environment that the child grows up in, the people he/she interacts with and the opportunities that he/she gets to stimulate the brain in different ways to encourage growth.

I hope this answer helps.
