Answer:
(-3, 1) and (2, -1)
Step-by-step explanation:
We'll just substitute in these coordinates.
First Pair:
2(-3) + 5(1) = -1
-6 + 5 = -1
-1 = -1
This works!
Second Pair:
2(5) + 5(-3) = -1
10 - 15 = -1
-5 ≠ -1
This does not work.
Third Pair:
2(2) + 5(-1) = -1
4 - 5 = -1
-1 = -1
This also works!
Fourth Pair:
2(-4) + 5(2) = -1
-8 + 10 = -1
2 ≠ -1
This does not work.

Clifford works 40 hours per week while working as a laboratory technician. He earns $453.60 for each week of work.
How much money does he earn in 1 hour?
How much money does he earn in 10 hours?
Answer:
he makes $11.34 and hour and $113.40 in 10 hours
Step-by-step explanation:
you divide 453.6 by 40 to get the 1 hour part and then divide it by 4 to get the 10 hour part
The amount of money that he earns in one hour and in 10 hours will be $11.34 and $113.4, respectively.
What is the rate?The rate is the ratio of the amount of something to the unit. For example - If the speed of the car is 20 km/h it means the car travels 20 km in one hour.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
Clifford works 40 hours per week while working as a laboratory technician. He earns $453.60 for each week of work.
The amount of money that he earns in each hour is given as,
Rate = $453.60 / 40
Rate = $11.34 per hour
The amount of money that he earns in 10 hours is given as,
⇒ $11.34 x 10

Given that u = 2.89 and v = 5.7, find the value of G when:
a G = 5u + 2y
Answer:
28.85
Step-by-step explanation:
Plug the values in and solve.
G = 5u + 2y
G = 5(2.89) + 2(5.7)
G = 14.45 + 11.4
G = 25.85

track team ran 8 in one day? miles (mi) in 5 days. If they ran the same distance each day, how far did they run?
Answer:
d = 1.75 miles
Step-by-step explanation:
A track team ran 8 and 3/4 miles in 5 days.
We need to find the distance covered by it each day. Let the distance is d.
[tex]8\dfrac{3}{4}[/tex] miles in 5 days
or
[tex]\dfrac{35}{4}[/tex] miles in 5 days.
[tex]1\ day=\dfrac{\dfrac{35}{4}}{5}\\\\=1.75\ \text{miles}[/tex]
So, each day the team will cover 1.75 miles.

Please help me
No picture included
Answer:
3
Step-by-step explanation:
What we can see from your table is that as x goes up by 1 y goes down by one
This means that the slope is -x
We also see that when x=0 y=6 which means that the y intercept is 6
this means your equation is
-x+6
We can now plug in x for 3 and get
-3+6=y
y=3
the answer is 3
Look at the angle. Which description is true?
It's less than 90°
It's equal to 90°
It's greater than 90°. HELP ASAP
Answer:
Less than 90 degrees
Step-by-step explanation:If it were equal to 90 degrees it could make a perfect square as the angle and if its more it would be open wide i guess im a bad explainer sorry
Hence , Option B is correct. It is less than 90 degrees.
What is an Angle?A figure which is formed by two rays or lines that shares a common endpoint is called an angle.
How To Solve:Observe the given figure. A perfect Right Angle is in the shape "L"(or opposite/mirror L also). One can measure or construct it using a protractor.
If the L seems to be bent inwards , then its an acute angle and if the L is bent outwards, then it is an obtuse angle.
From the given figure it can be concluded that the angle formed is an acute angle and hence its is less than 90 degrees.

Tommorrow is my test I really need to get goingI need some help?
Answer:
m = 2, c = -8.
Step-by-step explanation:
The general form of a straight line equation is
y = mx + c where m = the slope and c is the y-intercept.
We are given the line
y = 2x + 4
Comparing this with the general form we see that the slope of this line = 2 and the y-intercept C is 4.
Now the given line y = mx + c is parallel to y = 2x + 4 which means that their slopes are the same so we conclude that m = 2.
Now we need to find the value of c which is the y intercept of y = mx + c.
Consider the points A and B:
A is the point where the line y = 2x + 4 intersects the x axis so y = 0 at this point , So substituting in the equation:
0 = 2x + 4
-4 = 2x
x = -2.
So the point A is (-2, 0)
B is the point where y = 2x + c cuts the x axis so here y = 0:
0 = 2x + c
2x = -c
x = -c/2.
Now we are given that the 2 intercepts are 6 units apart, so:
-c/2 - (-2) = 6
-c/2 + 2 = 6
-c/2 = 4
-c = 8
c = -8.

[tex]\dfrac{5}{2}k-2=\dfrac{5}{2}\cdot\dfrac{2}{5}\left(\dfrac{5}{2}k-2\right)=\dfrac{5}{2}\left(\dfrac{2}{5}\cdot\dfrac{5}{2}k-\dfrac{2}{5}\cdot2\right)\\\\ =\boxed{\dfrac{5}{2}\left(k-\dfrac{4}{5}\right)}[/tex]

A plane is going to fly 300 miles at a planned speed of 530 mph. The flight will have an average headwind of w miles per hour the entire time, meaning the plane is flying directly against the wind. The time
Tin hours of the flight is a function of the speed of the headwind w, in mph, and can be modeled by
300
T(W) =
530-W
I need help with the bottom part. What does t(110) mean I’m this situation etc.
Answer:
T(100) represents that the plane flies against the wind at 110mph for 0.714 hours
Step-by-step explanation:
Given
[tex]w = headwind[/tex]
[tex]T = time[/tex]
Model:
[tex]T(w) = \frac{300}{530 - W}[/tex] -- This was not properly presented in your question
Required
What does T(110) means
First, we calculate T(110):
Substitute 110 for w in [tex]T(w) = \frac{300}{530 - W}[/tex]
The expression becomes
[tex]T(110) = \frac{300}{530 - 110}[/tex]
[tex]T(110) = \frac{300}{420}[/tex]
[tex]T(110) = 0.714[/tex] -- approximated
T(100) represents that the plane flies against the wind at 110mph for 0.714 hours

find the area the get the premiraterStep-by-step explanation:add
The area of this rectangle is 8cm2
(3x + 1) cm
(2x + 5) cm
Work out the value of x
Answer:
The value of [tex]x = \frac{1}{6}[/tex]
The length of the rectangle [tex]= \frac{3}{2}[/tex] cm
The width of the rectangle = [tex]\frac{16}{3}[/tex] cm
Step-by-step explanation:
Step(i):-
Given that area of the rectangle = 8 cm²
Length of the rectangle (l) = 3x+1
width of the rectangle (w) = 2x+5
The area of the rectangle = length × width
Given that area of the rectangle = 8 cm²
Step(ii):-
Now
(3x+1) ( 2x+5) = 8
⇒ 3x(2x+5) +1(2x+5) =8
6 x² + 15x + 2x +5 =8
⇒ 6 x² + 17x -3 =0
⇒ 6 x² + 18x -x -3 =0
⇒ 6 x ( x+3) -1(x+3) =0
⇒ 6x -1 =0 and x +3 =0
[tex]6x = 1[/tex] and x =-3
[tex]x = \frac{1}{6}[/tex]
The length of the rectangle
[tex]= 3 (\frac{1}{6} ) +1 \\= \frac{3}{2}[/tex]
The width of the rectangle
[tex]= 2 (\frac{1}{6} ) +5[/tex]
= [tex]\frac{16}{3}[/tex]
