Answer:
a=b=0
Step-by-step explanation:
y=(ax)/b so now plug in the points
first 0=6a/b
next 2=3a/b
0=6a
2b=3a
a,b =0
You probably put the wrong problem but this is what I got.
Which table has a constant of proportionality between y and 2 of 0.6?
Choose 1 answer:
A line passes through the points (-1, 4) and (3, -8). A second line passes through
(-1,8) and (2, 11).
A) Write the equation of each line. Show all work.
Answer:
y = -3x + 1, y = x + 9
Step-by-step explanation:
An equation consists of a slope and the y-intercept. To find the slope, you need to plug the values into the slope formula.
y2 - y1/ x2 - x1
= -8 - 4/ 3 - (-1)
= -12/ 4
= -3
The slope of the first line is -3.
To find the y-intercept, you need to plug in either one of the coordinates into the equation, y = -3x + b
-8 = -3(3) + b
-8 = -9 + b
1 = b
The equation, for the first one, is y = -3x + 1
Line 2:
11 - 8/ 2 - (-1)
= 1
y = 1x + b
11 = 1(2) + b
11 = 2 + b
9 = b
y = x + 9
find the slope-intercept equation of the line that passes through (-7,2) and had a slope of 0
Answer: Y=0x+b
Step-by-step explanation:
Y=mx+b is what we need to set it to.
Since we already know the slope, we can go ahead and find the y-intercept to complete the equation
(-7,2), here -7 is the x and 2 is the y value
y=mx+b
plug all the known information now and solve for b (y-intercept)
y is 2, m (slope) is 0, x is -7
2=0(-7)+b
2=0+b
2=b
y=0x+2 or simply y=2
Answer:
y = 2
Step-by-step explanation:
The line is a horizontal line thru (-7, 2)
Equation: y = 2
Find the interest rate for a bank account that earned $81.60 in interest over 4 years and that had a principal of $510

Riley invested $5,100 in an account paying an interest rate of 7\tfrac{3}{4}7 4 3 % compounded quarterly. Ryan invested $5,100 in an account paying an interest rate of 7\tfrac{1}{4}7 4 1 % compounded daily. After 7 years, how much more money would Riley have in her account than Ryan, to the nearest dollar?
Answer: 257
257 in delta math
Step-by-step explanation:
After 7 years, Riley would $441.5 more have in her account than Ryan.
What is compound interest?Compound interest is the interest calculated on the principal and the interest accumulated over the previous period.
Given that Riley invested $5,100 in an account paying an interest rate of [tex]7\tfrac{3}{4}[/tex]% compounded quarterly. Ryan invested $5,100 in an account paying an interest rate of [tex]7\tfrac{1}{4}[/tex] % compounded daily, we need to find that after 7 years how much more money would Riley have in her account than Ryan,
[tex]A = P(1+r/n)^{nt[/tex]
Where A = amount
P = principal
r = rate
n = number of times the amount is compounded and t = time
Riley = compounded quarterly,
[tex]A = P (1 + r / 4)^{4t[/tex]
[tex]A = 5100(1+0.019375)^{4(7)}\\\\A = 5100(1.019375)^{28}\\\\\\[/tex]
[tex]A = 8728.13[/tex]
Therefore, in 7 years Riley has $8728.13.
Ryan = compounded daily,
[tex]A = P (1 + r / 365)^{365t[/tex]
[tex]A = 5100(1 + 0.00019)^{356(7)}\\\\A = 5100(1.00019)^{2555}\\\\A = 8286.64[/tex]
Therefore, in 7 years Ryan has $8286.64.
Riley will have $441.5 more.
Hence after 7 years, Riley would $441.5 more have in her account than Ryan.

Answer:
y = 48
Step-by-step explanation:
Plug in 7 for x:
y = x² - 1
y = (7)² - 1
Simplify. Remember to follow the order of operations, PEMDAS.
PEMDAS stands for:
Parenthesis

First, solve the power, then subtract:
y = (7)² - 1
y = (7 * 7) - 1
y = (49) - 1
y = 48
48 is your value for y.

The height x of the equilateral triangle is 7√3 inches.
What is an Equilateral triangle?Equilateral triangles are triangles that have all their sides and angles equal to each other. The three angles are 60 degrees each.
Therefore,
The side length of the equilateral triangle is 14 inches.
Therefore, To find the height of the triangle using the Pythagoras theorem.
c² = a² + b²
14² - 7² = b²
b² = 196 - 49
b² = 147
b = 7√3
Hence, The height x of the equilateral triangle is 7√3 inches.
