To get an A in her math class, Jada needs to have at least 90% of the total number of points possible. The table shows Jada’s re

sults before the final test in the class.
Jada’s points total points possible
row 1 Homework 141 150
row 2 Test 1 87 100
row 3 Test 2 81 100
row 4 Test 3 91 100
Does Jada have 90% of the total possible points before the final test? Explain how you know.
Jada thinks that if she gets at least 92 out of 100 on the final test, she will get an A in the class. Do you agree? Explain.

Find the midpoint of the line segment that joins points P(-4,3) and Q(9,14)?

k0ka [10]

Given the following points:

Point P: (-4, 3)

Point Q: (9, 14)

To be able to find the midpoint of the line segment, we will be using the following formula:

$\text{ Midpoint = }\frac{x_1+x_2}{2},\frac{y_1+y_2_{}}{2}$

We get,

$\text{ Midpoint = }\frac{x_1+x_2}{2},\frac{y_1+y_2}{2}$ $\text{= }\frac{(-4)+(9)_{}}{2},\frac{3_{}+14_{}}{2}$ $\text{ = }\frac{5}{2},\frac{17}{2}$

Therefore, the midpoint of the line segment is 5/2, 17/2.

Choose the solution(s) of the following system of equations x2 + y2 = 6 x2 – y = 6

ElenaW [278]

<h2>Answer</h2>

$x=\sqrt{6}, y=0\\ x=-\sqrt{6} , y=0\\x=\sqrt{5} , y=-1\\x=-\sqrt{5} , y=-1$

Or as ordered pairs: $(\sqrt{6} ,0),(-\sqrt{6} ,0),(\sqrt{5} ,-1),(-\sqrt{5} ,-1)$

<h2>Explanation</h2>

Lets solve our system of equations step by step

$x^2+y^2=6$ equation (1)

$x^2-y=6$ equation (2)

1. Solve for $x^2$ in equation (2)

$x^2-y=6$

$x^2=6+y$ equation (3)

2. Replace equation (3) in equation (1) and solve for $y$

$x^2+y^2=6$

$6+y+y^2=6$

$y^2+y=0$

$y(y+1)=0$

$y=0$ or $y=-1$

3. Replace the values of $y$ in equation (3) and solve for $x$

- For $y=0$

$x^2=6+y$

$x^2=6$

$x=\sqrt{6}$ or $x=-\sqrt{6}$

- For $y=-1$

$x^2=6+y$

$x^2=6-1$

$x^2=5$

$x=\sqrt{5}$ or $x=-\sqrt{5}$

So, the solutions of our system of equation are:

$x=\sqrt{6}, y=0\\ x=-\sqrt{6} , y=0\\x=\sqrt{5} , y=-1\\x=-\sqrt{5} , y=-1$

How is the graph of log x + 6 translated from the graph of log x?

Korolek [52]

It could be 2 things
y=log(x)+6 or
y=log(x+6)

if it the first one
y=logx to y=(logx)+6
moved up 6 units

if 2nd one
y=logx to y=log(x+6), that is move the graph 6 units to left
