Proportion of y and x
y = kxGiven :
y = 55x = 1/4Solving :
55 = k/4k = 55 x 4k = 220Line a passes through the points (-2,1) and (1,-1). Line b passes through the points (-3,2) and (-1,0). DO lines a and b intersect? Explain.
Answer:
You can draw a graph.

Two angles of a quadrilateral measure 125° and 35°. The other two angles are in a ratio of 3:5. What are the measures of those two angles?
Answer:
120° and 80°
Step-by-step explanation:
quadrilateral = 360°
125° + 35° = 160°
360° - 160° = 200°
3/5 of 200° = 120°
200° - 120° = 80°
Answer:
Step-by-step explanation:
Finding the missing angles of quadrilateral:
Ratio of other two angles = 3 : 5
Other two angles are 3x , 5x
Sum of all angles of quadrilateral = 360
125 + 35 + 3x + 5x = 360
Combine like terms
160 + 8x = 360
Subtract 160 from both sides
8x = 360 - 160
8x = 200
Divide both sides by 8 to isolate x
x = 200/8
x = 25
5x = 5*25 = 125
3x = 3*25 = 75
The other two angles are 125° , 75°
Solve the following system of equations using elimination.
X + 2y = 5
3x + 5y = 14
Answer:
x = 3
y = 1
Step-by-step explanation:
x + 2y = 5 ------------(1)
3x + 5y = 14 ---------(2)
(1) × 3 : 3x + 6y = 15 ------ (3)
(3) - (2) : y = 1
y = 1, x + 2(1) = 5
x = 3
A piece of string is 144 inches long. Isabel wants to cut it into 2 pieces so that one piece is five times as long as the other. How long is each piece?
Answer:
24 inches120 inchesStep-by-step explanation:
The lengths can be found by considering their ratio:
short : long = 1 : 5
The sum of the ratio units is 1+5 = 6, and the sum of the lengths is 144 inches. That means each "ratio unit" stands for (144 in)/6 = 24 inches of length.
The lengths are ...
1 : 5 = 24 in : 120 in
The pieces are 24 inches and 120 inches in length.
__
Equivalently, you can let s represent the shorter length. Then 5s is the longer one, and their total is ...
s +5s = 144
s = 144/6 = 24
5s = 5(24) = 120
The lengths are 24 inches and 120 inches.

Alyssa is getting gas for her car. Her car’s 15-gallon tank has 1/5 a tank of gas left. If gas costs $2.699 per gallon, how much will she pay for gas, rounded to the nearest cent?
Answer:
$32.39
Step-by-step explanation:
She has a 15-gallon tank and it has 1/5 a tank of gas left (so about 3/15)
Because she needs to refill it and already has 1/5, she'll only need to pay for 4/5 a tank of gas (12/15).
So the equation should be 12 times $2.699.
12 × 2.699 = 32.388
Then, round to the nearest cent.
32.388 = $32.39
Hope this helped !
Find the solutions to x2 = 12.

x² = 12 ( take square root of both sides )
x = ± [tex]\sqrt{12}[/tex] = ± [tex]\sqrt{4(3)}[/tex] = ± ( [tex]\sqrt{4}[/tex] × [tex]\sqrt{3}[/tex] ) = ± 2[tex]\sqrt{3}[/tex]
kate has a coin collection. she keeps 7 of the coins in the box, which is only 5% of her entire collection. what is the total number of coins in kate's coin collection?
Answer:
140
Step-by-step explanation:
5 percent is 5% or 5 out of 100
5 / 100 = 7 / x
Cross multiply to get
5x = 700
Divide both sides by 5
x = 140

Which is an equation of the line that passes through the points (5, 2) and (10, -3)? HELP
Answer:
y = − x + 7
Step-by-step explanation:
let D be the line that passes through the points (5, 2) and (10, -3)
Then D has an equation of the form D: y = mx + p
Now we need to find m and p in order to be able to write the equation of the line D:
[tex]m = \frac{2-(-3)}{5-10} = \frac{5}{-5} = -1[/tex]
Since the point (5 , 2) lies on the line D then :
2 = -1 × (5) + p
then
2 = -5 + p
then
p = 2 + 5
= 7
then
p = 7
Conclusion:
Since m = -1 and p = 7
then
[tex]D : y = -x + 7[/tex]

B) 7776 π cm3
C) 36 π cm3
D) 24 π cm3
Answer:
A) 972π cm³
Step-by-step explanation:
d = 18 cm

help! p(x) = 4x^4 - 10x^3 + 8x - 1
x = 8
Answer:
p(8) = 11,327
Step-by-step explanation:
Hey there!
In order to find the answer, all we need to do is subtitute the x values for 8
After substituting, the equation will look like this:
[tex]p(8)=4(8)^4-10(8)^3+8(8)-1[/tex]
Now we simplify
8 to the power of four is 4096 and when you multiply that by 4, you get 16384
8 to the power of 3 is 512 and when you multiply that by -10, you get -5120
8 times 8 is 64
And then there is -1
Now all we have to do is combine all the answers together for one final answer
16384-5120+64-1 is equal to 11327
So the output of this function when you input 8 is 11,327
