Answer:
Q1 2. Q2 3.
Step-by-step explanation:
to solve a system of equations, you would usually have to use either elimination or substitution. however, in both of these problems, Y is given directly so that's unnecessary
for these, all you have to do is plug in y and then solve for x, where x is then the first number in the ordered pair and y is the second number.
Q1 48/-6 = -8, so the answer is (-6,-8)
Q2 10/2=5, so the answer is (5, -1)

If a ramp has a slope of 1/10 what is the angle of elevation for the ramp
Answer:
What angle should a ramp be?
Maximum slope for hand-propelled wheelchair ramps should be 1" of rise to every 12" of length (4.8 degree angle; 8.3% grade). Maximum slope for power chairs should be 1.5" rise to 12" length (7.1 degree angle; 12.5% grade). Minimum width should be 36" (inside rails) - (48" is ideal)

Is the dilation an enlargement or reduction?
The point of dilation is about what coordinate?
What is the scale factor?
Answer:
Is the dilation an enlargement or reduction?
Reduction
The point of dilation is about what coordinate?
0,0
What is the scale factor?
1/3
Step-by-step explanation:
The dilation is a reduction. The point of dilation is about coordinate (0,0). The scale factor is 1/3.
What is a transformation?A point is transformed when it is moved from where it was originally to a new location. Translation, rotation, reflection, and dilation are examples of different transformations.
On a coordinate plane, the pre-image rectangle has points (0, 0), (6, 0), (6, -3), and (0, -3).
The image has points (0, 0), (2, 0), (2, -1), and (0, -1).
The required figure has been attached below which represents the dilation.
As we can see that the dilation is a reduction.
The point of dilation is about coordinate (0,0).
This result of dilating a given triangle with a scale factor is 1/3.

B. The slope is 6
C. y-intercept is -3
E. y-6x= -3
F. (1/2, 0)
Step-by-step explanation:
I can't do the graph because I don't know how to input a picture but I hope this helped!
This is for the second half of the page:
2. the slope of y=3 is 0 so m=0
to graph just draw a line horizontally at 3

You ask 8 students how many letters are in their first name. One person says 6. The other 7 students say a different number of letters. Find the experimental probability of someone having 6 letters in their name based on this experiment.
Answer:
Step-by-step explanation:
Since only one out of eight said they had six letters
P(6)=1/8
The experimental probability of someone having [tex]6[/tex] letters in their name based on this experiment is [tex]\frac{1}{6}[/tex] .
What is experimental probability ?Experimental probability of an event is the ratio of the number of outcomes in which a specified event occurs to the total number of trials, not in a theoretical sample space but in an actual experiment.
[tex]Experimental \ probability = \frac{Total \ number \ of \ outcomes}{Number \ of \ favorable \ outcomes}[/tex]
We have,
Total number of students [tex]=8[/tex]
Person having [tex]6[/tex] letters in the name [tex]=1[/tex]
Other [tex]7[/tex] person says different number of letters.
So,
Experimental probability of someone having [tex]6[/tex] letters in their name is determined ;
[tex]Experimental \ probability = \frac{Total \ number \ of \ outcomes}{Number \ of \ favorable \ outcomes}[/tex]
[tex]=\frac{1}{6}[/tex]
So, Experimental probability of someone having [tex]6[/tex] letters in their name is [tex]\frac{1}{6}[/tex] , which is determined using the above given formula.
Hence, we can say that the experimental probability of someone having [tex]6[/tex] letters in their name based on this experiment is [tex]\frac{1}{6}[/tex] .

Which of the following best describes the solution of the system of equations below?
Answer:
D
Step-by-step explanation:
-8x + y = -3..... (equ 1)
9x - y = 3.....(equ2)
y = 8x - 3
-y = -9x + 3(divide both sides by -1*)
hence ..y = 9x - 3
then write y = y in terms of x
which will give you 8x - 3 = 9x - 3
and solve for x which will be N/A

The balance in her account at the end of 3.5 years is $6074.05.
What is the balance in her account at the end of 3.5 years?The balance in her account is the sum of the interest earned and the amount of money deposited.
Simple interest = amount deposited x time x interest rate
$5800 x 0.0135 x 3.5 = $274.05

Las edades de cuatro hermanos forman una progresión aritmética, y su suma es 32 años. El mayor tiene 6 años más que el menor. Halla las edades de los cuatro hermanos.
Answer:
The ages of the four siblings are: 5, 7, 9 and 11 years old.
Step-by-step explanation:
The computation of the age of the four siblings is shown below:
Given that
n = 4
a1 =? a2 =? a3 =? a4 =?
a4 = a1 + 6 years
S4 = 32
Based on the above information
As we know that
Sn = (a1 + a4) × n ÷ 2
S4 = (a1 + a4) × 4 ÷ 2
32 = (a1 + a1 +6) × 2
16 = 2a1 + 6
2a1 = 10
a1 = 10 ÷ 2
= 5
So, a4 = a1 +6
= 5 +6
= 11
a4 = a1 + (4-1) × d
11 = 5 + 3 × d
d = 6 ÷ 3
= 2
So,
a2 = a1 + d
= 5 + 2
= 7
a3 = a2 + d
= 7 + 2
= 9
Hence, The ages of the four siblings are: 5, 7, 9 and 11 years old.

Answer:
y = 3/4x -7/4 or y = 0.75x -1.75
Step-by-step explanation:
The two point form of the equation of a line is useful when you are given 2 points and asked for the equation.
y = (y2 -y1)/(x2 -x1)·(x -x1) +y1
y = (35 -14)/(49 -21)·(x -21) +14 . . . . . . fill in given points
y = 21/28(x -21) +14 . . . . . . . . . . . . . . . simplify a bit
y = 3/4(x -21) +14 . . . . . . . . . . . reduce the fraction
y = 3/4x -15 3/4 +14 . . . . . . . .eliminate parentheses
y = 3/4x -7/4 or y = 0.75x -1.75

B. She used y-values where she should have used x-values.
C. She did not keep the order of the points the same in the numerator and the denominator.
D. She should have added the values, not subtracted them.
Answer:
C. She did not keep the order of the points the same in the numerator and the denominator.
Step-by-step explanation:
She needs to switch 1 with 17 so it can be [tex]\frac{17-1}{18-14}[/tex]. It needs to equal [tex]\frac{y2-y1}{x2-x1}[/tex].
Answer:
C. She did not keep the order of the points the same in the numerator and the denominator.
Step-by-step explanation: Hope this helps
The correct slope should look like: 1-17/14-18
If you do 1-17 for the numerator then 14-18 must be the denominator (the slope is 4: -16/-4 = 4)
The equation to find the slope of a line is (y2-y1)/(x2-x1). (x1,y1) is the first coordinate point, (x2, y2) is the other. It does not matter which coordinate point you use first, as long as you remain consistent.
