Answer:
Step-by-step explanation:
No this is not proportional , because the ratio of y/x for each one is not same ,
As for 1st one ,
y/x =4/2 =2
for 2nd one ,
y/x=16/4 = 4 and so on
so they re not equal that's why they are not proportional

Answer:
15.) -21f - 16
16.) 5s + 2t
Step-by-step explanation:
15.)
-12f - 16 - 9f (Distribute 4 through the parentheses)
-21f - 16 (Collect like-terms)
16.)
4s + 2t + s + s - s (Since two opposites add up to zero, remove them from the expression)
4s + 2t + s (Collect like terms)
Find the area of an equilateral triangle with side length 9.2 cm. Round your answer to 1 DP.
Answer:
Area=36.66 cm^2
Step-by-step explanation:
First, you need the height.
Use the Pythagorean theorem:
hypotenuse^2=height^2+(1/2 base)^2
It's one-half base because it's an equilateral triangle.
1/2 base =4.6
(9.2)^2-4.6^2=height^2
84.64-21.16=height^2
height^2=63.48
height=7.97
Area=(1/2)(base)(height)
Area=(1/2)(9.2)(7.97)=36.66 cm^2

how many solutions does y=-7x+8 y=-7x-8 have?
Answer:
no solutions
Step-by-step explanation:
Given the 2 equations
y = - 7x + 8 → (1)
y = - 7x - 8 → (2)
Substitute y = - 7x - 8 into (1)
- 7x - 8 = - 7x + 8 ( add 8 to both sides )
- 7x = - 7x + 16 (add 7x to both sides )
0 = 16 ← not possible
This indicates the system has no solutions
Hey there!
The answer to your question is [tex]no[/tex] [tex]solutions[/tex]
To solve this, we will set the equations equal to eachother. We know that since the two expressions, [tex]-7x+8[/tex] and [tex]-7x-8[/tex] both equal [tex]y[/tex], then the expressions are equal. (Somebody comment what property that is, I forgot what it's called) So:
[tex]-7x+8=-7x-8\\[/tex]
Add [tex]8[/tex] to both sides:
[tex]-7x+16=-7x[/tex]
Add [tex]7x[/tex] to both sides:
[tex]16 = 0[/tex]
Therefore, there are [tex]no[/tex] [tex]solutions[/tex].

Step-by-step explanation:
Of the 10,000 participants in the Cooper Run/Walk, 42% were runners and one-third of the runners were female. Sally, a female runner, finished faster than exactly 90% of the female runners. What is the greatest number of female runners who could have finished faster than Sally?
Answer: 140 female runners
Step-by-step explanation:
First find out the number of runners:
= 42% * 10,000
= 4,200 runners
Then find out the number of female runners:
= 4,200 * 1/3
= 1,400 female runners
Sally finished faster than 90% of the female runners which means that 10% finished faster or at the same time as her.
= 10% * 1,400
= 140 female runners
If m<1=(6x+25), and m<2=(x+5), find m<2
Answer:
Assuming they are equal to each other, X = -4
Step-by-step explanation:
6x + 25 = x + 5
Subtract 5 from both sides
6x + 20 = x
subtract 6x from the left side
20= 5x
divide by 5
-4 = x
Select the three number bonds that represent factor pairs of the number 56. CLEAR CHECK Number bond: 1 times 56 = 56. Number bond: 4 times 14 = 56. Number bond: 5 times 6 = 56. Number bond: 7 times 8 = 56.
Answer:
The answer is -
Number bond: 1 times 56 = 56.
Number bond: 4 times 14 = 56.
Number bond: 7 times 8 = 56.
Step-by-step explanation:
We can define a factor pair as a set of two factors, which, when multiplied together, give a particular product.
For example -
5 and 6 are factors of 30 because 5×6 = 30
Now,
Given -
Number bond: 1 times 56 = 56. ...................(1)
Number bond: 4 times 14 = 56. ...................(2)
Number bond: 5 times 6 = 56. ...................(3)
Number bond: 7 times 8 = 56. ...................(4)
In equation (1)
1 times 56 = 1×56 = 56
⇒1 and 56 are the factor pairs of 56
Satisfies
In equation (2)
4 times 14 = 4×14 = 56
⇒4 and 14 are factor pairs of 56
Satisfies
In equation (3)
5 times 6 = 5×6 = 30 ≠ 56
⇒5 and 6 are not factor pairs of 56
Not Satisfies
In equation (4)
7 times 8 = 7×8 = 56
⇒7 and 8 are factor pairs of 56
Satisfies
∴ we get
The answer is -
Number bond: 1 times 56 = 56.
Number bond: 4 times 14 = 56.
Number bond: 7 times 8 = 56.
solve the inequality y - 8 > 13

Select all the expressions that are equal to 761 ÷ 5. 7610 ÷ 50 762 ÷ 6 76.1 ÷ 0.05 7.61 ÷ 0.5 0.761 ÷ 0.005
Answer:
7610 ÷ 50 and 0.761 ÷ 0.005
Step-by-step explanation:
761/5 is 152.2
7610 ÷ 50 = 152.2
762 ÷ 6 = 127
76.1 ÷ 0.05 = 1522
7.61 ÷ 0.5 = 15.22
0.761 ÷ 0.005 = 152.2

Answer:
m∠PNO = 60°
m∠O = 33°
Step-by-step explanation:
∡NPO is 87° because it's a vertical angle with the 87° angle
3) ∡PNO is supplementary to the 120° angle (they must add to 180°)
4) m∠O = 180 - (60 + 87) = 33

Write an equation of the line that passes through (−2,1) and is parallel to the line y=3x−4.
Equation: y=
Answer:
y = 3x+7
Step-by-step explanation:
the slope of parallel lines are the same so the slope is 3
y-y1 = 3(x - x1)
y- 1 = 3(x- -2)
y-1 = 3x +6
y = 3x +7

80p2 - 180r2
Answer:
80p2 - 180r2
20(4p²-9r²)
20(2p+3r)(2p-3r)
Answer:
20(2p - 3r)(2p + 3r)
Step-by-step explanation:
Given
80p² - 180r² ← factor out 20 from each term
= 20(4p² - 9r²) ← difference of squares which factors in general as
a² - b² = (a - b)(a + b)
4p² - 9r²
= (2p)² - (3r)² ← with a = 2p and b = 3r
= (2p - 3r)(2p + 3r)
Thus
80p² - 180r² = 20(2p - 3r)(2p + 3r) ← in factored form

Why is it possible for the solution to a system of linear equations with two variables to be expressed as an ordered pair?
Step-by-step explanation:
ok lets imagine if the variables were x and y
the equation would be as follows
y=3x+2
y=-1/3x+7
The answer will be an ordered pair, (x,y) because that specifies exactly where on graph, instead of a general location which you would get if you only had the x or only had the y
