Find the slope between (9,-2) and (-1,5)
Answer:
7/-10
Step-by-step explanation:
subtract
5-(-2) = 7
-1-9 = -10
Answer:
The slope is -0.7 or -7/10
Step-by-step explanation:
For 10 x values decreased, the y values go up 7 values. So the slope is -7/10 or -0.7

Julio pald 1.2 times his normal hourly rate for each hour he works over 30 hours a week Last week he worked 43 hours and earned $574.56
Answer:
482.70
Step-by-step explanation:
First, find out how much he earned per hour last week. 576.56 divided by 43 is 13.41.
Second, multiply his hourly earnings by 1.2, 1.2*13.41=16.09 So he earns 16.09 per hour
Lastly, multiply 16.09 by 30, 16.09*30=482.7 So he earns about $482.70 each week.
Divide 3/5 by 1/2 as a reduced fraction.
Answer:
You can't divide two fractions together, so you multiply the second fraction by taking its reciprocal.
[tex]\frac{3}{5} * \frac{2}{1} \\\\= \frac{6}{5}[/tex]
If we divide the [tex]\frac{3}{5}[/tex] by [tex]\frac{1}{2}[/tex] so the decrease fraction should be [tex]\frac{6}{5}[/tex].
Given that,
The fraction is [tex]\frac{3}{5}[/tex].And, the other fraction is [tex]\frac{1}{2}[/tex].Now it should be divided to come as a reduced fraction.So, the decreased fraction should be
[tex]= \frac{3}{5} \times \frac{2}{1} \\\\= \frac{6}{5}[/tex]
Therefore we can conclude that if we divide the [tex]\frac{3}{5}[/tex] by [tex]\frac{1}{2}[/tex] so the decrease fraction should be [tex]\frac{6}{5}[/tex].

A. (0,5)
B. (0,0)

D. (3,-4)
E. (19,0)
Answer:
A. y-intercept
B. Both
C. x-intercept
D.Neither
E. x-intercept.
Step-by-step explanation:
A y-intercept is recognized when there is a 0 at the x coordinate. A x-intercept is recognized when there is a 0 at the y-coordinate. The origin (0,0) is considered the x and y-intercept. In a neither situation, the coordinates will have another number besides zero.

A testicle cuff is a ring-shaped device around the scrotum between the body and the testicles which when closed does not allow the testicles to slide through it. A common type has two connected cuffs, one around the scrotum and the other around the base of the penis. They are just one of many devices to restrain the male genitalia. A standard padlock, which cannot be removed without its key, may also be locked around the scrotum.
. Consider the following standards.
MAFS.912.F-BF.1.1b: Combine standard function types using arithmetic operation. For example, build a function that models the temperature of a cooling body by adding a constant function to a decaying exponential, and relate these functions to the model. MAFS.912.F-BF.1.1c: Compose functions. For example, if T(y) is the temperature in the atmosphere as a function of height, and h(t) is the height of a weather balloon as a function of time, then T(h(t)) is the temperature at the location of the weather balloon as a function of time.
Part A: Describe the difference in combining functions and composing functions.
Part B: Give a real-world example of combining functions.
Part C: Give a real-world example of composing functions.
Part A:
A combined function is defined by combining with existing functions using addition, subtraction, multiplication or division.
A composite function is created by plugging one function into another.

A florist charges $25 for a vase plus $4.50 for each flower. The total charge for the vase and flowers is given by the function f(x) = 4.50x + 25. How will the graph change if the vase’s cost is raised to $35? if the charge per flower is lowered to $3.00?
a) The graph change if the vase’s cost is raised to $35 is the line
[tex]y=4.5x+35[/tex]
b)The charge per flower is lowered to $3.00 is the line
[tex]y=3x+25[/tex]
We have given that the function
[tex]f(x) = 4.50x + 25[/tex]
A florist charges $25
Now we have given condition the cost is raised to 35$
We use we use the slope intercept form
What is the slope intercept form?
[tex]y=mx+C[/tex]
y is function f(x) C=vase cost, and m= charge per flower
Therefore we get,
[tex]y=f(x),m=4.50 and c=25[/tex]
we have given condition C=35$
So the line will just move up to have a y-intercept at (0,35) the equation will be,
[tex]y=4.5x+35[/tex]
Therefore,
The graph change if the vase’s cost is raised to $35 is the line
[tex]y=4.5x+35[/tex]
We have given that the charge per flower is lowered to 3$
So the slope
[tex]m=3[/tex]
Here the m value is being changed so your line will just flatten out a bit and the new equation will be
[tex]y=3x+25[/tex]
The charge per flower is lowered to $3.00 is the line
[tex]y=3x+25[/tex]

3(2x-5)=-15
Answer:
x=0
Step-by-step explanation:
Divide both sides by the numeric factor on the left side, then solve.
3(2x−5)=−15
Step 1: Simplify both sides of the equation.
3(2x−5)=−15
(3)(2x)+(3)(−5)=−15(Distribute)
6x+−15=−15
6x−15=−15
Step 2: Add 15 to both sides.
6x−15+15=−15+15
6x=0
Step 3: Divide both sides by 6.
6x/6 = 0/6
x=0

9. Suppose GH = JK. HI = KI and QI = ZL. How can you prove that GHI is congruent to JKL ?
You can use SAS to prove the triangles are congruent.
You can use SSS to prove the triangles are congruent.
You can use SSA to prove the triangles are congruent.
There is not enough information to prove that the triangles are congruent.
Answer:
C. SSSStep-by-step explanation:
Since we are not given any angle measure and three side measure, we can prove these triangles congruent by SSS.
To prove triangle GHI and JKL are congruent, rule SSS is used.
What are congruent triangles?Two triangles are said to be congruent if all three corresponding sides are equal and all the three corresponding angles are equal in measure.
Different rules of congruency are as follows.
SSS (Side-Side-Side)
SAS (Side-Angle-Side)
ASA (Angle-Side-Angle)
AAS (Angle-Angle-Side)
RHS (Right angle-Hypotenuse-Side)
Given
Triangles GHI and JKL
GH = JK
HI = KI
QI = ZL
All three sides are equal in both triangles.
By side-side-side theorem,
ΔGHI ≅ΔJKL
Hence, by SSS theorem, it is proved the triangles are congruent.

bigtown=5/7=95
Answer: The big town team scored 95 points.
Step-by-step explanation: Given that the big town football team outscored its opponents 5:2 last season and their opponents scored 38 points.
We are to find the points scored by big town team.
Let 5x and 2x represents the points scored by big town team and their opponents.
Then, according to the given information, we have
2r = 38
r = 38/2
r = 19
Therefore, the points scored by big town team is given by
5 X 19 = 95.
Thus, the big town team scored 95 points.
