Find the rate of change
Answer:
3rd option
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the rate of change and c the y- intercept )
Given
2x + 8y = - 4 ( subtract 2x from both sides )
8y = - 2x - 4 ( divide terms by 8 )
y = - [tex]\frac{2}{8}[/tex] x - [tex]\frac{4}{8}[/tex] , that is
y = - [tex]\frac{1}{4}[/tex] x - [tex]\frac{1}{2}[/tex] ← in slope- intercept form
with rate of change m = - [tex]\frac{1}{4}[/tex] and y- intercept c = - [tex]\frac{1}{2}[/tex]
7r^2=-70
-10v^2=-810
Answer:
Step-by-step explanation:
I'll focus on -10v^2=-810 and will aim to find the solution, v. Dividing both sides by -10, we get v^2 = 81, so that v = ±9 (two roots).
The other equation, 7r^2 = -70, has no real solutions.
r^2 = -70 yields r = ±i√10 (two imaginary solutions)

Find the diagram attached
Using the similarity theorem of a triangle;
GH/FG = FG/EF
x/15 = 36/39
x/15 = 12/13
Cross multiply
13x = 12 * 15
13x = 180
x = 180/13
x = 13.85
Hence the value of x to the nearest hundredth is 13.85

A soccer ball is kicked upward from the ground with a speed of 96 feet per second. Its height h, in feet, after t seconds is given by the equation h(t) = -16² +96t.
HCL many seconds will it take the soccer ball to reach its maximum height?
Answer:
After 3 seconds
Step-by-step explanation:
Given
[tex]h(t) = -16t^2 + 96t[/tex]
Required
Seconds to attain maximum height
The maximum of a quadratic function [tex]y = ax^2 + bx + c[/tex] is calculated using:
[tex]x = -\frac{b}{2a}[/tex]
So, we have:
[tex]t = -\frac{b}{2a}[/tex]
Where:
[tex]a = -16[/tex] and [tex]b = 96[/tex]
So:
[tex]t = -\frac{96}{2 * -16}[/tex]
[tex]t = -\frac{96}{-32}[/tex]
Cancel out negatives
[tex]t = \frac{96}{32}[/tex]
[tex]t = 3[/tex]
Justyna invested $1500 in an account at a 2.5% interest rate compounded annually. She made no deposits or withdrawals on the
account for 7 years. Determine, to the nearest dollar the balance in the account after the 7 years.
4.200
Answer:
$1783.03
Step-by-step explanation:
Annually compounding interest formula:
PV(1+i)ⁿ
1500(1+.025)⁷
1500(1.025)⁷
1783.028631
which rounds to
1783.03
Answer:
$1783.03
Step-by-step explanation:
You use the formula for finding the interest rate.
So 1500(1+.025)^7
Which you put that in a calculator and it comes to out to 1783.0286. Then just round up.

Which is the best description for the lines m and k?
A)
parallel
B)
perpendicular
intersecting and parallel
D
intersecting but not perpendicular
===================================================
Explanation:
I've highlighted lines m and k in red (see diagram below). We'll ignore the other lines. On those red lines, I've added blue points with their coordinate locations.
Line m has point A = (-3, 5) and B = (-1, -3). Let's use the slope formula to find the slope through these points
m = (y2-y1)/(x2-x1)
m = (-3-5)/(-1-(-3))
m = (-3-5)/(-1+3)
m = -8/2
m = -4
The slope of line AB, aka line m, is -4.
-------------
Line k has points C = (1, 5) and D = (3, -3) on it. We'll use the slope formula to get...
m = (y2-y1)/(x2-x1)
m = (-3-5)/(3-1)
m = -8/2
m = -4
The slope of line CD, aka line k, is -4
---------------
Both lines m and k have the same slope of -4. Therefore, the two lines are parallel. Parallel lines always have the same slope, but different y intercepts. So these lines will never intersect one another.

Increase 18 by a half
Answer:
36
Step-by-step explanation:
if we were decreasing it would be 9 but if we are increasing it, it would be 36
just multiply by 2 or divide by 2
Answer:
27
Step-by-step explanation:
increasing by 1 half is like dividing. 4 increased by one half would be 6, because half of four is 2, and you add that on to four. increasing 18 by half, divide 18 by 2, that = 9 then add 9 onto 18. the answer is 27

Sort the numbers from LEAST TO GREATEST . > 6.82 , 6.803 , 6.650 , 6.68
Answer:
6.650, 6.68, 6.803, 6.82
Step-by-step explanation:
You just treat the decimals as you would whole numbers. Try imagineing them as whole numbers and its a lot easier like this. 6.82 and 6.68 as 682 and 668, you can clearly see 668 is lower than 682 so it comes first. Therefore, 6.68 is lower than 6.82 and comes first.
It costs $23,000 to attend 1 year at Texas State University, and I already saved up $4,000. How much money would I have to save each month for the next year to have the full $23,000?
Round to the nearest hundredth.
Answer:
[tex]\$1583.33[/tex]
Step-by-step explanation:
Let [tex]d[/tex] be the amount of money you need to save each month to have the full $23,000.
We can write the following inequality:
[tex]4,000+12d\geq 23,000[/tex]
Solving for [tex]d[/tex]:
[tex]4,000+12d\geq 23,000,\\12d\geq 19,000\\d\geq \approx \boxed{\$1583.33}[/tex]

Jack is wrong because he used the distributive property wrong. On the top equation, you see 2(4k - 3). The 2 multiplies into the (), so basically you have
2 x 4k - 2 x 3
which gives you
8k - 6
Answer:
Taniyah
Step-by-step explanation:
Taniyah is correct because you need to:
diistribute : 8k - 6 - 6k = 14
combine like terms : 2k - 6 = 14
add 6 to both sides : 2k - 6 + 6 = 14 + 6
simplify : 2k = 20
divide both sides by the same factor : 2k/2 = 20/2
simplify : k = 10

Find the slope of the line through the given points.
(-1,1) and (3, -7)
Answer:
Slop of the line M = -2
Step-by-step explanation:
Given coordinates;
(-1 , 1) , (3 , -7)
Find:
Slop of the line
Computation:
We know that;
x1 = -1
x2 = 3
y1 = 1
y2 = -7
Slop of the line M = Δy / Δx
Slop of the line M = (y2 - y1) / (x2 - x1)
Slop of the line M = (-7 - 1) / [3 - (-1)]
Slop of the line M = (-8) / [3 + 1]
Slop of the line M = (-8) / (4)
Slop of the line M = -2
