Match the graph with the correct equation
A: Y= -2X + 5
B: Y= -X + 3
From: SLOPE-INTERCEPT FORM: PART 1
Answers
Answer:
The equation for this picture(graph) is:
y = -x+3
Slope: Rise/run
= 3/3
= 1
= -1 (negative because the slope is decreasing).
Y-intercept is where the line touches the y-axis

As we know,sum of angles on a straight line is 180 degree..
(5z-4)+90+39=180
=>5z-4+90+39=180
=>5z-4+129=180
=>5z+125=180
=>5z=180-125
=>z=55÷5
Hence,the value of z=11 degree

f(x) = (x - 6)(x - 2)?
Answers
Answer:
y = 12 → (0|12)
Step-by-step explanation:
f(x) = (x - 6)(x - 2)
y = (x - 6)(x - 2)
y = x² - 6x - 2x + 12
y = x² - 8x + 12
y = 0² - 8*0 +12
y = 12

Is the line through points p (3,-5) and Q(1,4)parallel to the line through points R( -1,1) and S (3,-3)
Answers
Answer:
No
Step-by-step explanation:
To find out if the lines that go through the pairs of points are parallel, we must find the slope of each line. If the slopes are equivalent, then they are parallel. If not, then they are not parallel.
We can use the slope formula to find the slope between two points. The slope formula is:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
where m is the slope between the points (x₁, y₁) and (x₂, y₂).
Lets first find the slope between points P and Q.
[tex]m=\frac{-5-4}{3-1}=\frac{-9}{2}=-4.5[/tex]
So the slope between P and Q is -4.5.
Now lets find the slope between the points R and S.
[tex]m=\frac{-3-1}{3-(-1)}=\frac{-4}{4}=-1[/tex]
So the slope between R and S is -1.
Since -4.5 does not equal -1, the lines are not parallel.

The required value of variable m is 15.
Gvien that,
A line segment AC is given, On which B is the midpoint,
AB = 3m + 5
and BC = 4m - 10
AB = BC
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
AC is the line segment where B is the midpoint on the line AC. So,
AC = AB + BC
AB = BC
3m + 5 = 4m - 10
m = 15
Thus, the required value of variable m is 15.

-SGO
Answers:
a) 80% nonfiction
b) 1200 fiction, 4800 nonfiction
=========================================
Explanation:
part (a)
We only have two choices: fiction or nonfiction
If 20% are fiction, then 100% - 20% = 80% are nonfiction.
The two percentages 20% and 80% add to 100% to represent all the books.
---------------------
part (b)
20% = 20/100 = 0.20
20% of 6000 = 0.20*6000 = 1200
we have 1200 fiction books
6000-1200 = 4800
and we have 4800 nonfiction books
Note how
80% of 6000 = 0.80*6000 = 4800
which helps confirm part (a)

The graph represents the gallons of water in a water tank with respect to the number of hours since it was completely filled. The total capacity of the water tank is gallons, and the rate of change is gallons per hour.
Answers
Answer:
Total capacity of the water tank is 400 gallons
Rate of change in water level is 20 gallons per hour
Step-by-step explanation:
The graph attached represents the gallons of water in a water tank with respect to the number of hours since it was completely filled.
The total capacity of the water tank is represented by the y-intercept of the graph that is 400 gallons.
Now to calculate the rate of change in water level we will take two points on the given line and find the slope.
There are two points (0, 400) and (5, 300) on the line.
So the slope of the line is (400-300)/(0-5)= -100/5= -20
This minus notation of slope shows that level of water is reducing and rate of change in water level is 20 gallons per hour.

Step-by-step explanation:
Equate the equation to zero
[tex]10a^{2}[/tex]-9a+2=0
[tex]10a^{2}[/tex]-5a-4a+2=0
5a(2a-1)-2(2a-1)=0
Write out the factors
(5a-2)(2a-1)=0
Then equate each factor to zero
5a-2=0 OR 2a-1=0
5a=2 OR 2a=1
a= [tex]\frac{2}{5}[/tex] OR a= [tex]\frac{1}{2}[/tex]
a=[tex]\frac{2}{5}[/tex] or [tex]\frac{1}{2}[/tex]
