w/8 - 4 = 20
add 4 on each side and divide by 8
subtract 4 on each side and multiply by 8
add 4 on each side and multiply by 8
subtract 4 on each side and divide by 8
Answer:
128Step-by-step explanation:
Step one:
given the expression w/8 - 4 = 20
the first operation is to isolate the term that has w by adding 4 to both sides
w/8 - 4+4 = 20+4
w/8 = 16
Required
the value of w
Step two:
the next step is to cross multiply
w=16*8
w=128

find the slope of the line through the pair of points (-4,12) , (-4,11)
is it undefined, 1, 0, or -1?
Answer:
Pretty sure its undefined
Step-by-step explanation:
Answer:
Undefined
Step-by-step explanation:
Looking at the change in x's theres no variation which means this is a vertical line, thus therefore this is an undefined line as the rise over the run or the change in y over the change in x will result in a divide by 0 situation making it (-4, all real numbers) aka undefined.
slope = rise/run = change in y/change in x = (y2-y1)/(x2-x1)

If M is in the interior of ∠RTD, m∠RTM = 40°, and m∠RTD = 65°, then m∠MTD = .
Answer:
MTD = 75
Step-by-step explanation:
RTD + RTM + MTD = 180
65 + 40 + MTD = 180
105 + MTD = 180
Subtract 105 from both sides.
MTD = 75

When two straight lines or rays intersect at a shared endpoint, an angle is generated. The measure of the angle ∠MTD is equal to 15°.
What is an angle?When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."
Given that point M is in the interior of ∠RTD. Also, the measure of ∠RTM=40°, and ∠RTD = 65°.
Now, since the two angles together form ∠RTD, therefore, we can write,
∠RTD = ∠RTM + ∠MTD
65° = 40° + ∠MTD
∠MTD = 65° - 40°
∠MTD = 15°
Hence, the measure of the angle ∠MTD is equal to 15°.

Write the equation of the line fully simplified slope-intercept form. help
Answer:
y = 4x -8
Step-by-step explanation:
The y intercept is -8 so our b term for y = mx + b is 8.
The line goes up 4 y values every one x value to the right
Answer:
y = 3x - 8
Step-by-step explanation:
To write the equation of the line in slope-intercept form, or y = mx + b, we have to find the y-intercept (b) and the slope(m).
To find the y-intercept, look at the graph at find where the line intercepts the y-axis. On this graph, the line intercepts at y = -8. Now we know the value of b.
To find the slope, look at the rise over run between two points. The line goes up by 3 every time it goes over 1. this means that our slope is 3.
Now we can input the values of the slope and the y-intercept into the equation.
y = 3x - 8
I hope this helps :)

Answer:
c = 100(x +10)²Step-by-step explanation:
The square of a binomial is ...
(x +a)² = x² +2ax + a²
Comparing this to your expression, we have ...
2a = 20 . . . . x-coefficient
a² = c . . . . . . constant term
Then ...
a = 20/2 = 10
a² = 10² = 100 = c

Maya will deposit $1,650 in an account that earns 5% simple interest every year. Her brother, James, will deposit $1,600 in an account that earns 8% interest compounded annually. The deposits will be made on the same day, and no additional money will be deposited or withdrawn from the accounts. Compare and contrast the two siblings' accounts after four year
Answer:
Step-by-step explanation:
Step one:
given data
Maya
P=$1650
r=5%= 0.05
t= 4 years
The simple interest expression is
A=P(1+rt)
A=1650(1+0.08*4)
A=1650(1+0.32)
A=1650(1.32)
A=1650*1.32
A=$2178
James
P=$1600
r=8%= 0.08
t=4years
The compound interest expression is
A=P(1+r)^t
A=1600(1+0.08)^4
A=1600(1.08)^4
A=1600*1.360
A=$2176
After 4 years Mayas' balance is $2178
After 4 years James' balance is $2176
the difference is =2178-2176=$2

(same signs add, different signs subtract)
-5x -7y = -38
(in the question there are two boxes at the side of the eqaution you should put (+)sign there as youre adding them)

Please help I have no clue
Answer:
c
Step-by-step explanation:
Please look at number 10. from the slope and write the equation for me
Answer:
y = 8x + 38
Step-by-step explanation:
To find the slope we set up y = mx + b and plug m (our slope) in and then plug in the point into x and y to find b (our y-intercept)
y = mx + b
y = 8x + b
6 = 8(-4) + b
6 = -32 + b
+32 +32
38 = b
So using our slope and our intercept we have our slope intercept
y = mx + b
y = 8x + 38
Hope this helps :)
Answer:
y - y1 = m(x - x1)
y - 6 = 8(x - (-4))
y - 6 = 8(x + 4)
y - 6 = 8x + 32
y = 8x + 32 + 6
y = 8x + 38
Step-by-step explanation:
First you input the given values ( m = 8 and (-4, 6)) into the point-slope equation.
After that, you multiply the 8 by the two terms inside the parentheses, giving you 8x and 32.
Then you add 6 to both sides of the equation to isolate the y.
The slope-intercept equation ends up looking like this: y = 8x + 38
Hope this helps :)
