Answer:

\huge \boxed{ \boxed{ \sf \: y = x + 15}}

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know:</h3>
  • linear equation
  • linear equation word problems
  • PEMDAS
<h3>tips and formulas:</h3>
  • linear equation:y=mx+b
<h3>let's solve:</h3>

all we need to care about the middle condition which is

<h3>the new test score is 15 points more than the original score</h3>

given that

original score is x

New score is y

if you pay attention to the given condition

we can find it same as linear equation

therefore

according to the question

the equation is

<h2>y=x+15</h2>

Which inequality defines the shaded region graphed below?
masha68 [24]

Answer:

Every ordered pair within this region will satisfy the inequality y ≥ x. Incorrect. The boundary line here is y = x, and the correct region is shaded, but remember that a dotted line is used for < and >. The inequality you are graphing is y ≥ x, so the boundary line should be solid.

A parabola can be represented by the equation y2 = –x. What are the coordinates of the focus and the equation of the directrix?
shutvik [7]

ANSWER

Focus:

(- \frac{1}{4} ,0)

Directrix:

x=\frac{1}{4}

EXPLANATION

The given parabola has equation:

{y}^{2}  =  - x

We compare this to the general equation,

{y}^{2}  =  - 4px

Comparing the coefficient of x, we have:

-4p=-1

p =  \frac{1}{4}

The focus is (-p,0)

(- \frac{1}{4} ,0)

The equation of the directrix is

x=p

x =  \frac{1}{4}
