Factor Theorem:
"If a is a root of a polynomial, (x - a) is a zero of the polynomial."
Therefore by Factor Theorem,
we have (x - 1)(x + 3) = x² + 2x - 3.

G is the incenter, or point of concurrency, of the angle bisectors of ΔACE.
Answer:
▢ [tex]$\overline{DG}$[/tex] ≅ [tex]$\overline{FG}$[/tex]
▢ [tex]$\overline{DG}$[/tex] ≅ [tex]$\overline{BG}$[/tex]
▢ [tex]$\overline{GE}$[/tex] bisects [tex]\displaystyle ∠DEF[/tex]
▢ [tex]$\overline{GA}$[/tex] bisects [tex]\displaystyle ∠BAF[/tex]
Step-by-step explanation:
As you can see, angles [tex]\displaystyle BAF[/tex] and [tex]\displaystyle DEF[/tex] form two half-kites, which you should know have two pairs of congruent sides, therefore segments [tex]\displaystyle GA[/tex] and [tex]\displaystyle GE[/tex] are what you call angle bisectours, which is why segments [tex]\displaystyle FG,[/tex] [tex]\displaystyle DG,[/tex] and [tex]\displaystyle BG[/tex] are congruent.

The equation for line s can be written as y = -8/7x - 4. Line t, which is perpendicular to line
s, includes the point (10, 9). What is the equation of line t?
Answer:
y=-8/7x-4
from, m1m2=-1
-8/7m2=-1
m2=7/8
again from, m=(y-y1)/(x-x1)
7/8=(y-9)/(x-10)
8(y-9)=7(x-10)
8y-72=7x-70
8y=7x-70+72
8y=7x+2

y - 28 = 12r
y - 28 / 12 = r
switch sides ^
r = y - 28 / 12

Lourdes plans to jog at least 1.5 miles. Write an inequality and solve an inequality to find x, the number of hours Lourdes will have to jog. She is running at 3.75 mph
Answer:
1.5 ≤ 3.75x
Step-by-step explanation:
Given that:
Distance, D to jog is atleast 1.5 miles
D ≥ 1.5 miles
x = number of hours to jog
Jog rate = 3.75 mph
Actual distance covered if jog last for X hours
Actual Distance = speed * time
Actual Distance = 3.75 * x = 3.75x
Hence,
D ≤ Actual distance
1.5 ≤ 3.75x

Answer:
(d) Eighteen divided by a number m is seven point two.
Step-by-step explanation:
The symbol ÷ is read "divided by", so the math sentence ...
18 ÷ m = 7.2
is read "eighteen divided by [a number] m is seven and two tenths."
__
"Seven and two tenths" can also be read as "seven point two."
If x and y vary inversely and x = -3 when y = 12, what is the constant of variation?
k=-36
Step-by-step explanation:
x inversely proportional to y
x=1k/y
where k = constant
x= -3, y= 12, k = ?
-3=k/12
k = -3 × 12
k = -36

Answer:
[tex]\huge \orange {\boxed {y = - \frac{5}{4}x + 5}} [/tex]
Step-by-step explanation:
Line is intersecting x and y axes at the points (4, 0) & (0, 5)
So, y- intercept (b) = 5
[tex] Slope\: (m) = \frac {(5-0)}{(0-4)} = - \frac {5}{4} [/tex]
Equation of line in slope intercept form is given as:
[tex] y = mx + b[/tex]
Plugging the values of m and b in the above equation, we find:
[tex]\huge \purple {\boxed {y = - \frac{5}{4}x + 5}} [/tex]
A pair of Jordans sold at retail for $180 and now sell for $330 after market. A. Is this a percent INCREASE or DECREASE, what is the PERCENT change?
Answer:
This is a percent INCREASE
The percent change is 83.33%
Step-by-step explanation:
Let us solve the question
∵ A pair of Jordans sold at retail for $180
∴ The initial price = 180
∵ Now it sells for $330 aftermarket
∴ The new price = 330
→ That means the new price is greater than the initial price
∵ The new price is greater than the initial price
∴ This is a percent INCREASE
∵ The percent of change = (amount of increase ÷ initial amount) × 100%
∵ The amount of increase = new price - initial price
∴ The amount of increase = 330 - 180 = 150
→ Substitute it in the rule of percent of increase above
∵ The percent change = [tex]\frac{150}{180}[/tex] × 100%
∴ The percent change = [tex]\frac{5}{6}[/tex] × 100%
∴ The percent change = 83.33%

A company bought a total of 412feet of cable to connect 3 computers to the wall outlet. Each computer needs the same amount of cable. How many feet of cable are needed to connect each computer?
Answer:
Each computer needs 3/2, or 1.5 feet of cable
Step-by-step explanation:
Firstly, we need to divide 4 1/2 by 3
Then we can make 4 1/2 an improper fraction.
We will also multiply 4 by 2 and then add 1
= 8 + 1
= 9
But;
9/2 = 4 1/2
In order to divide 9/2 by 3/1, we will change 3/1 to 1/3 and then multiply
= 9/2 × 1/3
= 9/6
= 3/2 or 1.5
Therefore, each computer needs 3/2, or 1.5 feet of cable.
Jan wants to protect the wooden box in question 4a by painting varnish on all of the outside surfaces, including the bottom. Will a container of varnish that covers 275 square inches be enough to protect the outside surfaces of the box?
Answer:
As this question is incomplete, but we will try to solve this question by adding our own data to understand the concept of the problem.
Explanation is given below
Step-by-step explanation:
As this question is incomplete, but we will try to solve this question by adding our own data to understand the concept of the problem.
In order to answer this question we need to have the dimensions of the box.
Let's suppose there are 6 outside surfaces of the box and are equal in dimension including the bottom side which Jan wants to varnish.
So,
Let's suppose,
Surface area of the cube = 6[tex]a^{2}[/tex]
Here, Surface area = 275 square inch
Surface area of the cube = 6[tex]a^{2}[/tex] = 275 square inch
[tex]a^{2}[/tex] = 275/6 = 45.833
a = [tex]\sqrt{45.833}[/tex]
a = 6.77 inches
Now, for the amount of the varnish, we need the spreading rate of the varnish to be used on the box,
Let's suppose it is = 11 square incher per litre.
So,
Required Varnish = Surface area / Spreading rate
Required varnish = 275 / 11
Required varnish = 25 liters
If the 1 container of varnish contains 25 liters then it will be sufficient to protest the outside surfaces of the box.

A teacher provides 4 sets of cupcakes for the class party. Each set contains 10 cupcakes. If the class has 24 students and each student eats 1 cupcake, how many are leftover?
A 0
B 40
C 16
D 24
Answer:
So 4 sets means 10 x 4=40
40 cupcakes in all
24 x 1=24 cupacakese aten.
40-24= 16
So 16 cupcakes left which i want to eat....:)

2. At one time, the ratio of in-state to
out-of-state tuition at Texas A&M
University in College Station, Texas
was about 3:11. About how much was
the out-of-state tuition if the in-state
tuition at that time was about $2400?
Answer:
The out-of-state tuition would be $8800.
Step-by-step explanation:
Given that:
The ratio of in-state tuition to out-state tuition = 3:11
If the tuition of in-state is $2400.
Let,
x represent the number of out-of-state tuition.
As the relation is directly proportional.
3 : 11 :: 2400 : x
Product of mean = Product of extreme
11*2400 = 3x
3x = 26400
Dividing both sides by 3
[tex]\frac{3x}{3}=\frac{26400}{3}\\x=8800[/tex]
Hence,
The out-of-state tuition would be $8800.
How do you determine which variable to substitute in for?
Answer:
Substituting for a Variable
If you know the value that the variable is equal to, you can substitute that value in for the variable in the expression! Let's look at an example. Since we know that x=5, we can directly substitute or replace the x in the expression x+3 with a 5 to solve for y!
