Step-by-step explanation:
y= -1/2x + 2
y=mx+b
b is the y intercept which is where the line passes through the point.
m is slope to find slope go to a point (ex- (0,4) and go to the next and to do that is up 1 over 2 which is 1/2 and the line is going left so it's negative

Answer:
$252
Step-by-step explanation:
The price of the computer is $400
On saturday it is on sale for 30% off
30% of 400 or .3 x 400 = 120
400 - 120 = 280
Then, if she gets there before 9am there is an addition 10% off of the sale price (280)
So, 10% of 280 or .1 x 280 = 28
280 - 28 = 252

Answer:
Before starting, parallel lines are lines on the same plane that never intersect with each other. From the figure, the pairs of parallel lines would be WX & ZY and WZ and XY. The only correct statement in the choices is letter B.
Answer:
Option A
Step-by-step explanation:
In trapezoid, one pair of opposite sides are parallel.
Parallel lines have the same slope.
So , we have to find the slope of four sides and from that we can show that it is a trapezoid.

to determine when the rock hit the ground.
[Recall that
v

is the initial velocity of the object and
h

is the inital height of the object.]
Answer:
in 6.36004793262 seconds
Step-by-step explanation:
h(t) = –16t^2 + v*t + h
0=-16t^2 + 70*t+ 202
t=(-70 ± sqrt((70^(2)-4*(-16)*202))/(2*(-16))
t=(-70 ± sqrt(4900+64*202))/-32
t=(-70 ± sqrt(4900+12928))/-32
t=(-70 ± sqrt(17828))/-32
t=(-70 ± sqrt(2*2*4457))/-32
t=(-70 ± 2 sqrt(4457))/-32
t=(-70 + 2 sqrt(4457))/-32
t=-1.98504793262
t=(-70 - 2 sqrt(4457))/-32
t=6.36004793262
since we need the time it will fall to the ground after it was thrown and time can't be negative, answer is

At East Middle School 28% of the students are in the band.If 168 students are in the band,how many students go to East Middle School?
Plz Help me.I will give you max points
Answer:
600
Step-by-step explanation:
% of students in the band = 28%
No. of students who are in the band = 168

So, 28/100×x=168
= 600
he center is consideirng signing up for an online game-rental service rather than buying the games. The table shows equipment cost and monthly fees for two services.
Equipment cost mouthy cost
Net games 99$ 8$
Equipment cost mouthy fee
anytime games 19$ 19$
1. Write and solve an inequality that represents the number of months the center could rent games from NetGames with its $175. Explain the solution in terms of the problem.
2. Write and solve an inequality to represent the number of months the center could rent games from Anytime Games. Explain the solution in terms of the problem.
3. Use your answers from 1 and 2 to justify which service the community center should purchase.
Answer:
see below
Step-by-step explanation:
From Netgames
175≥ 99 + 8x
Subtract 99 from each side
175-99 ≥ 99-99 + 8x
76≥ 8x
Divide each side by 8
76/8 ≥ 8x/8
9.5≥ x
He can get up to 9 months along with the equipment
From Anytime
175≥ 19 + 19x
Subtract 19from each side
175-19 ≥ 19-19 + 19x
156≥ 19x
Divide each side by 19
156/19 ≥ 19x/19
8.210526316≥ x
He can get up to 8 months along with the equipment
Since he can get more months from Netgames, he should rent from netgames
Answer:
The center should rent from Net games
Step-by-step explanation:
1. Net games:
175 ≥ 99 + 8x
175 - 99 ≥ 8x
76 ≥ 8x
9.5 ≥ x
It can rent games for 9 and a half months
2. anytime games:
175 ≥ 19 + 19x
156 ≥ 19x
8.2 ≥ x
It can rent games for 8 months
3. Since the center can rent games for a longer period of time with Net games (9.5 months compared to anytime's 8 months), it should rent from there.

Each point where vertical cables are attached to the spanning cable of a bridge has forces pulling in three directions. This situation can be modeled in terms of the unknown forces with the matrix equation below Solve this equation for F and round answers to three decimal points
Answer:
f1: 0.440, f2: 0.931, f3: 1.519
Step-by-step explanation:
To solve the system of equations we need to use the inverse of matrix A, as follows:
A x F = C
A^-1 x A x F = A^-1 x C
I x F = A^-1 x C
where I is the identity matrix.
The inverse of A is:
1.450 -0.392 -0.090
A^-1 = -0.074 -0.022 0.1536
-0.406 0.7122 -0.060
(computed with Excel)
The multiplication between the inverse of A and C gives:
0.440
A^-1 x C = 0.931

a. yes; k = -5 b. no c. yes; k = 4/5 d. yes; k = - 4
The answer :
4/5
Step-by-step explanation:
4x-5y=0
subtract 4x on both the sides
4x-4x-5y = 0-4x
-5y = -4x
divide by -5 on both the sides
-5y/-5 = -4x/-5
y =( 4/5 )x

D 10%
Please answer need help
if you answer this simple question you will get 15 point. but explain and give reason fast
Answer:
x = 45 degree as it is an alternate angle we use 135 degree to prove supplementary angles across the straight line add up to 180 degree.
Therefore we prove 180-135 = 45 degree and say all angles on straight line add up to 180 degree, and recognize x is an alternate angle as the arrow straight lines are parallel and create precise alternate lines from which we can prove multiple supplementary and alternate angles.
Supplementary can be either angle will always be supplementary from either 45 degree angle matched with any 135 degree as they don't have to be together to be supplementary they only have to equal 180 degree to be a supplementary angle.

At the start of the week, Crystal’s bank account had a balance of $280. Each day from Monday to Friday, she used her debit card to pay $5 for parking. She wrote a check for $42, and made two deposits of $75 each. She also withdrew $200 in cash at an ATM. What was Crystal’s balance at the end of the week?
Evaluate the expression below to solve the problem.
280 + 5(–5) + (–42) + 2(75) + (–200)
answer down here
$
Answer:
$163
Step-by-step explanation:
Happily, they've given us the equation already.
280 + 5(–5) + (–42) + 2(75) + (–200)
280 - 25 - 42 + 150 - 200
Keep in mind your negative signs!
280 - 67 + 150 - 200
280 - 67 - 50
213 - 50
= $163
This can all be done on the calculator, but it can also be done mentally or written out, as I've done.
