Answer:
‒5
Step-by-step explanation:
‒x‒2y=‒(‒5)‒2(5)
=5‒10
=‒5
i hope it helps you
Answer:
-(-5)-2(5)
negative wih negitive will become positive so
-(-5) become positive 5 andwhen when we multiply negative and positive we get negative so -2(5) become -10 so finally 5-10=-5 thank you!!
Can any kind soul help me please
Answer:
(i) we will be finding the acceleration here, in the first 20 seconds the velocity was 10
a = velocity/time
a = 10/20
a = 0.5 ms -2
(ii) difference in distance of the bus and bicycle will be given by formula of velocity
velocity of bicycle
10 * 80 = distance
800 metres
velocity of bus
for first 20 seconds( distance= velocity* time)
200 metres
from 20 seconds to 60 seconds, it will be for 40 seconds
then distance will be,
400 metres
final 20 seconds
200 metres
adding the distances of bus it will be 800 metres.
the difference in distance will be 0 metres.
this is wat i think

Stephen calculated the linear regression equation to be y = -7.8x + 246.3. Using this equation, find the cost of a
room 5 city blocks away from Time Square.
1) $195
2) $207
3) $238
4) $285
What’s the answer?
Answer:
$207
Step-by-step explanation:
Given the following :
Data:
X : Distance From Times Square (city blocks)
Y: Cost of a Room (dollars) (y)
The linear regression model generated for the data :
y = -7.8x + 246.3
y = predicted variable ; - 7. 8 = slope of model ; x = predictor variable ; 246.3 = intercept
Using the model:
The cost of a Room 5 block away :
x = 5
y = -7.8(5) + 246.3
y = - 39 + 246.3
y = $207.3
Find the slope of the line passing through the points -5,6 and 9,6
find the linear function from the table

The number of bacteria in a Petri dish grows by 10 percent every hour. After the growth, about 100 bacteria die. Suppose there are 500 bacteria, how many bacteria are alive after 1 hour
Answer:
450 bacteria
Step-by-step explanation:
Find growth that comes from precentage.
a = pw
a = 1.10(500)
a = 550
Then kill 100 bacteria.
b = 450

Answer:
Step-by-step explanation:
The three angles of a triangle always have to equal 180 in the end, so if you use the method which is the 4 in this instance, it is an obtuse angle that is equal to the top and left angle. You can add 1 and 2 to get 4, and do 4-3 to get 1+2, So, 4=1+2.
bruh no one is helping me with my questions anymore so could someone please help me on this :/
which of these statements are true
1. Vertical angles formed by intersecting lines are directly across from each other and are sometimes congruent.
2. An angle bisector divides an angle into two congruent angles
3. A midpoint divides a line into two congruent lines.
4. Perpendicular lines form congruent right angles.
5. An angle measuring 225 degrees is obtuse.
6. If two angles form a linear pair, then they are complementary.

John caught 24 trout in bass while on a fishing trip. The total weight of his catch was 137 pounds. The average weight of a trout was 2.5 pounds, and the average weight of a bass was 8 pounds. How many trout and how many bears did he catch?
Answer:
trouts = 10 and bears = 14
Step-by-step explanation:
Let number of trouts and bears be x and y respectively.
This means that since he caught 24 trout and bass, we have;
x + y = 24 - - - (eq 1)
Now, average weight of trout is 2.5 pounds and average weight of bass is 8 pounds.
Thus;
2.5x + 8y = 137 - - - (eq 2)
From eq(1), let's make x the subject.
Thus;
x = 24 - y
Put 24 - y for x in eq(2)
2.5(24 - y) + 8y = 137
60 - 2.5y + 8y = 137
5.5y + 60 = 137
5.5y = 137 - 60
y = 77/5.5
y = 14
x = 24 - 14
x = 10
Thus, trouts = 10 and bears = 14

Find the y-intercept and x-intercept of the line. 5x-4y=20
Answer:
y intercept : (0,-5) slope 5/4
x= 4+ 4y/5
Step-by-step explanation:
5x-4y=20
+4y=20 + 4y add 4 to each side
5x= 20/5 + 4y/5 divide both sides by 5
x = 4 +4y/5

2. Tina uSUally brings her children every Sunday afternoon at the children's park in their barangay. The park is 350m Iong and 200m wide complete with slides and
swings for children to play. If is surounded by a pathway of unifom width for children who loves biking and jogging. Suppose the total area of the park and the pathway is 74,464 m2.
a. How wide is the pathway of the park?
b. If you were Tina, woulad you like your children fo go biking and jogging in that park?
Answer: kindly check explanation
Step-by-step explanation:
Given the following :
Total area of parknand path way = 74,464 m2.
Dimension of park = 350m by 200m
Using the area of rectangle formula:
Area = Length * width
Area of park = 350m * 200m
Area of park = 70,000
Area of path = (74,464 - 70,000) = 4,464m2
Since path has uniform width, then width of the the path is sqrt(4464) = 66.8m
2.) the path of the park seems a bit narrow, hence, I wouldn't love children to bike and jog in such a narrow path
What is the rate of return for an investor who pays $1,054.47 for a 3-year bond with an annual coupon payment of 6.5% and sells the bond 1 year later for $1,037.19?What is the rate of return for an investor who pays $1,054.47 for a 3-year bond with an annual coupon payment of 6.5% and sells the bond 1 year later for $1,037.19?
Answer:
4.53%
Step-by-step explanation:
We are told that:
From the question, we have a 6.5 % coupon
Hence = 6.5 × $10
= $65
Price of the bond one year later = $1,037.19
$1,054.47 - $1,037.19
= $17.28
Rate of Return
= ($65.00 - $17.28)/$1,054.47
47.72 ÷ 1054.47 = 0.045254962
0.045254962 × 100 =
4.5254962 %
Approximately = 4.53%

Answer: q-56 > 0
Step-by-step explanation:
STEP 1
Equation at the end of step 1
(q + 12) - 2 • (q - 22) < 0
STEP 2
Equation at the end of step 2
56 - q < 0
STEP 3
Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number
q-56 > 0

Find the linear equation for the following functions
Answer:
1st one) y = x - .8
Step-by-step explanation:
1st one) you start by finding the slope of the line which can be found with y1 - y2/x1 - x2 (in this case: 3.6-2.4/2-1 which = 1/1, or the slope is one). now that we know the slope we need to find the x intercept or the point that the line intercepts the x axis, or when y = 0. We know that that for every one we subtract from x, we subtract one from y (hence the slope 1/1). so when we subtract 1.2 from the y we subtract 1.2 from the x. so the x intercept is -.8. If we put this in y = mx+b we get y = x - .8
