x2 - 9x - 36
Answer:
-7x - 36
Step-by-step explanation:
x X 2 - 9 x X - 36
2x - 9x - 36
Answer:
( x + 3 ) ( x - 12 )
Step-by-step explanation:
x^2 - 9x - 36
= x^2 + 3x - 12x - 36
= x ( x + 3 ) - 12 ( x + 3 )
= ( x + 3 ) ( x - 12 )

The coordinates of the vertices of the triangle shown are P(-7, 6), Q(5,-4), and R(-7, 4). Which measurement is closest to the length of PO in units? es A) 14.4 units B) 14.8 units 15.2 units D) 15.6 units
Step-by-step explanation:
the length of PQ =
√(-7-5)²+(6+4)²
=√(-12)²+(10)²
= √144+100
=√244

Using Trigonometry,
[tex] \tan(x) = \dfrac{6}{8} [/tex]use the equation below to find y,if m=4,x=5, and b=9. y=mx-b
Step-by-step explanation:
Y=4(5)-9
=11
you must follow the formula given
Answer:
y=11
Step-by-step explanation:
y=mx-b
mx-b=y
4 * 5 - 9 = y
20 - 9 = y
11 = y
At 12 noon if the temperature is 38°C and if it decreases at the rate of 2°C per hour, then what would be the temperature at 5pm?
Answer:
38-2(5) = 28
So the temperature would be 28 degrees celsius
Answer: Teperature at 5PM will be 28°C
Ok so at 12 its 38°C
And it dcreases at 2°C an hour, we need to find the teperature at 5 o clock.
The number of hours between 12 and 5 mutiplied by 2 will give us the trail in temperature and then subtracting the trail i temperature witht the temperature a 12 will give us the teperature at 5 o clock.
SO,
hours between 12 PM and 5 PM is 5 hours
As, the temperature decreases at a uniform rate of 2°c per hour
⇒5×2°C
⇒10°C
Now the temperature at 5 PM will be 38°C-10°C=28°C
Is (1,-4) a solution to the equation y=-2/?
A yes
В. no
Answer: B.no
Step-by-step explanation:
To figure this out, plug (1, -4) into the equation y=-2x. 1 is the x value, so we plug it into the x. -4 is the y value, so we plug it into the y spot. In the end we get -4=-2(1). Is this true? No, it isn't. Therefore it is not an answer

HI PLEASE ANSWER BEFORE 12:00a.m. EST
Answer:
D
Step-by-step explanation:
Amanda's unit rate would be
s=50m
while Mary's is
s=60m
60-50 is 10, meaning the answer would be D.
Mary saves $10 more than Amanda every month.
Hope this helps! :)
Hi there!
We can find an equation that models Amanda's savings using the equation:
y = km, where:
k = rise / run (Amount/months)
Plug in a set of values from the table:
k = 100/2 = 50
y = 50m
We know that Mary saves y = 60m dollars a month, so we can determine the correct comparison by plugging in a value of 1 month into both equations:
Amanda:
y = 50(1) = $50
Mary:
y = 60(1) = $60
The difference between Mary's and Amanda's savings is $60 - $50 = $10, so each month, Mary saves $10 more than Amanda.
The correct answer is D.

Step-by-step explanation:
the distance between the points (1, 4) and (-5, -4) on the coordinate plane =
√(-5-1)² + (-4-4)²
=√(-6)²+(-8)²
=√36+64
=√100

parallel to y = -2/5 and passes through 2, -8
Answer:
y = -8
Step-by-step explanation:
When y = -2/5, the slope is 0.
Seeing this, we can make the equation the same as the y-value of the point given.
Hence,
y = -8
