Answer:
y = -5/2x - 4
Step-by-step explanation:
(0,-4) and (-4,6)
Slope:
m=(y2-y1)/(x2-x1)
m=(6+4)/(-4-0)
m=10/-4
m= -5/2
Slope-intercept:
y - y1 = m(x - x1)
y + 4 = -5/2(x - 0)
y + 4 = -5/2x
y = -5/2x - 4

FIRST CORRECT ANSWER GETS BRAINLIEST! CALCULATE THE SLOPE FOR INTERVAL A.
Answer:
60
Step-by-step explanation:
The slope is going to be rise over run which is feet/seconds
from (0,0) to (600,10) which is a the line rises up 600 feet and runs 10 seconds
so it is just 600/10 which is 60

Which regular polygon would have each of its interior angles measure 120°?
nonagon
hexagon
octagon
heptagon
Answer:
Hexagon
Step-by-step explanation:
If in a regular polygon, each interior angle = 120 deg, then each exterior angle = 180–120 = 60 deg. So the polygon has 360 deg/60 deg = 6 sides. The figure is a regular hexagon.
April and Bill went to the grocery store to buy chocolate bars. April bought 4 small chocolate bars and 6 large chocolate bars , while Bill bought 4 small chocolate bars and 3 large chocolate bars. If April paid $16.50 and Bill paid $11.25, what is the price of a single large chocolate bar?
Step-by-step explanation:
To do this equation, we could put it in terms of algebra, lets say the large chocolate bars are represented by L and the small bars by S
April
4S + 6L = $16.50
Bill
4S + 3L = $11.25
Looking at this, we can see that the difference between the two purchases is that Bill bought three less large chocolate bars, this means the difference in total cost equals three large chocolate bars. Using this knowledge.
$16.50 minus $11.25 = $5.25
$5.25 = Three Large Bars
Divide this by three to get the cost of one large bar.
$1.75 is the cost of one single large bar.
Answer:
April: 4x+6y=16.5
Bill: 4x+3y=11.25
solving the two equations simultaneously will give you y=1.75

What is the variance of the data set (4,6,7,10)
Answer:
4.6875Step-by-step explanation:
Given data set
(4,6,7,10)To find
VarianceSolution
The Variance is defined as the average of the squared differences from the mean.The mean is:
x = (4 + 6 + 7 + 10)/4 = 6.75The variance is:
σ² = [(4 - 6,75)² + (6 - 6.75)² + (7 - 6.75)² + (10 - 6.75)²]/4 = 4.6875Shirts at A water park come in green or yellow they come in small or large they also have short Sleeves oat long sleeves how many Combinations of different colors size and sleeve are there

Find the value of x so that the ratios are equivalent. 9:x and 54:8
I keep trying 48 its never right
Answer:
Maybe it is right, but you need to phrase it a different way
Step-by-step explanation:
like x= 48
or 48
or 9:48
you know
The value of x so that the ratios are equivalent is 48.
How to obtain real measurements from the ratio of two measurements?Suppose the real measurements were "a" and "b"
Then their ratio will be formed as
[tex]\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}[/tex]
where is a common factor (not 1)
Which shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator.
Thus, a = px, b = qx
Therefore, the value of x so that the ratios are equivalent.
9:x and 54:8
x= 48
or 9:48
Hence, the value of x so that the ratios are equivalent is 48.

y = 4x - 6
y = 4x + 10
What is the solution to the system?
Answer:
No Solution
Step-by-step explanation:
y = 4x - 6
y = 4x + 10
You can set them equal to each other because they both are y.
4x-6=4x+10

How many solutions does 4x + 5 = 6(x + 3) - 20 - 2x have? Show your work.
Answer:
X∈∅
Step-by-step explanation:
4x + 5 = 6(x + 3) - 20 - 2x
distribute the 6
4x+5=6x+18-20-2x
collect like terms
4x+5=4x+18-20
4x+5=4x-2
cancel equal terms
5=-2
statment is false for any value of x

im new can anyone help
Answer:
We have the equation:
[tex]W = W_0*(\frac{1}{2})^{0.36*t}[/tex]
Where:
W₀ is the initial area of the wound, and t is the time in days.
Now, if we initially have a wound of 25 mm^2, then:
W₀ = 25mm^2
And we can replace it in the equation, then we get:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*t}[/tex]
We want to know the size of this wound after:
a) 1 day.
We know that t represents time in days, so here we just need to replace t by one, then:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*1} = 19.5 mm^2[/tex]
b) 1 week
Again, t represents the time in days, so we need to write this in days.
We know that:
1 week = 7 days.
then t = 7
The size of the wound after 7 days is:
[tex]W = (25mm^2)*(\frac{1}{2})^{0.36*7} = 4.36 mm^2[/tex]

What’s the answer??????
Answer:
x=50
Step-by-step explanation:
Answer:
x = 50
Step-by-step explanation:
So the equation is 2x+25=125. you first subtract the 25 from the 125 which you'll get 100 and then divided by 2 which leaves the x alone and so 100/2 = 50 so x= 50
Compare and contrast the formulas for the volume of a pyramid and the volume of a cone.
Because a pyramid has a non-circular base, the volume is always described in square units, but the volume of a cone is stated in cubic units.
Because a pyramid has a non-circular base, the volume is always described in cubic units, but the volume of a cone is stated in square units.
Both formulas are 13Bh, but the base of a pyramid is always a square.
