Answer:
a - b + c = - 3
Explain
a = - 2
b = - 5
c = - 6
Now,
a - b + c = - 2 - (-5) + (-6)
= - 2 + 5 - 6
= - 8 + 5
= - 3
is this a function graph?
Answer:
No, this is a relation
Step-by-step explanation:
You can do a vertical line test to see if a function is actually a function or not. Simply draw vertical lines over the graph
If the x-value has 2 or more y values then it is NOT A FUNCTION
Answer:
No! This is not a function.
Step-by-step explanation:
If you write a vertical line through the graph, it will cross through it twice. That means it's NOT a function graph.

The greater of two consecutive EVEN numbers is 40 less than twice the smaller number. Find the larger number
Answer:
44Step-by-step explanation:
z - some integer
2z - first given even integer (the smaller one)
2z+2 - even integer consecutive to 2z (the larger one)
2(2z) - twice the smaller number
2(2z) - 40 - the number 40 less than twice the smaller number
2(2z) - 40 = 2z + 2
4z - 40 = 2z + 2
2z = 42
2z+2 = 42+2 = 44
check:
2(2z)-40 = 2(42)-40 = 84-40 = 44
HEY HEY HEYYYYY...............BITCONEEEEEEEEEEECT! 9*10^8/4*10^6 in Scientific Notation (I'll post another if this one is answered. Im strugglin.)
Answer:
[tex]225[/tex]
Step-by-step explanation:
[tex]\frac{9\cdot \:10^8}{4\cdot \:10^6}=\frac{9\cdot \:10^{8-6}}{4}=\frac{10^2\cdot \:9}{4}[/tex]
[tex]\frac{10^2\cdot \:9}{4}=\frac{2^2\cdot \:5^2\cdot \:9}{2^2}[/tex]
Cancel out common factor:

solve the equation by finding the square roots
w^2-36=-64
Answer:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation : w^2-36-(-64)=0 Step by step solution : Step 1 : Polynomial Roots Calculator : 1.1 Find roots (zeroes) of : F(w) = w 2 +28 so the answer could be 2.176 or 30.
Write an equation in slope intercept form for the line that has a slope of -4 and passes through the point (1,2)
Answer:
y=-4x+6
Step-by-step explanation:
what you have to do for this problem you have take the point 1,2 slide it over to the left one since the slope is negative and up 4 then you do that till you cross the y axis, but in this case you only have to do it once

Given the points below, find XY. Round to
the nearest hundredth.
X(-8, 2) and Y(7,-4)
Answer: 16.16
Step-by-step explanation:
xy in this situation, will be the distance between the two points.
(-8,2) (7,-4) Find the distance between the points
To ind the distance, find the difference in the x and y values,square them and add them to find the obtained number square root.
2-(-4) = 6
-8 - 7 = -15
6^2 + (-15)^2 = d^2 where d is the distance
36 + 225 = d^2
261 = d^2
d= [tex]\sqrt{261}[/tex]
d= 16.1554 rounded to the nearest hundredth is 16.16
X - 6 - 8 = -19 + x
Answer: infinite solutions, one solution, zero, no solution
Answer:
No solution.
Step-by-step explanation:
[tex]x-6-8=-19+x[/tex]
Subtract x from both sides:
[tex]x-6-8-x=-19+x-x[/tex]
[tex]-6-8=-19[/tex]
[tex]-14=-19[/tex]
Since both sides are not equal, there is no solution.

What is the reasoning?
Answer:
yes, i agree. the right angle is 90 and 90+90=180. The law of the congruent angle states that if one angle in a the plane is right then the other connected must be as well, making line L 180.
Step-by-step explanation:
i badly explained it however you should get the answer correct with that. i think... use your brain in addition to mine.

which statement describes the meaning of the point (010) on the graph?
A After 10 hours there are 10.000 bacteria.
B. After 10 hours there are no more bacteria
C The population began with 10,000 bacteria
D. The population is multiplying itself by 10 each hour
Answer:
Option (C)
Step-by-step explanation:
From the graph attached in the picture,
Graph shows the relationship between time and the population of a culture of bacteria.
Option (A).
After 10 hours there are 10000 bacteria.
Since, at t = 0, number of bacteria = 10000.
False.
Option (B).
After 10 hours there are no more bacteria.
Since, from the given graph bacteria population is increasing exponentially every hour.
Therefore, from t = 0, where the population was 10000, bacteria will be much more in the numbers.
False.
Option (C).
The population began with 10000 bacteria.
True.
Option (D).
The population is multiplying itself by 10 each hour.
Since, growth is exponential therefore, bacteria population is growing faster.
False.
Option (C) is the answer.

Answer:
[tex] - 14[/tex]
Step-by-step explanation:
[tex]2a = - 36 + 8[/tex]
When the - 8 is moved after the equals.. It changes sign
[tex]2a = - 28[/tex]
[tex]a = \frac{ - 28}{2} [/tex]
[tex]a = - 14[/tex]

solve for k. k/2 +1/2=3
Answer:
[tex]k = 5[/tex]
Step-by-step explanation:
Solve for [tex]k[/tex] :
[tex]\frac{k}{2} + \frac{1}{2} = 3[/tex]
-Multiply both sides of the equation by the denominator [tex]2[/tex] :
[tex]2 \times \frac{k}{2} + \frac{1}{2} = 3 \times 2[/tex]
[tex]k + 1 = 6[/tex]
-Subtract both sides by [tex]1[/tex]:
[tex]k + 1 - 1 = 6 - 1[/tex]
[tex]k = 5[/tex]
So, the value of [tex]k[/tex] is [tex]5[/tex].
