Answer: the point (3.667, 0.8)
Step-by-step explanation:
We want to find the point at which the lines:
h(x) = -(3/5)*x + (7/5)
and
k(x) = (-8/3)*x + (404/45)
If the lines intersect, then we must have:
h(x) = k(x)
if we write the functions we get:
-(3/5)*x + (7/5) = (-8/3)*x + (404/45)
Now we need to solve this for x.
-(3/5)*x + (8/3)*x = (404/45) - (7/5)
(8/3 - 3/5)*x = 404/45 - 63/45 = 341/45
(40/15 - 9/15)*x = 341/45
(31/15)*x = 341/45
x = (341/45)*(15/31) = 3.667
Now we can input this value of x in the functions to get the output.
h(3.667) = -(3/5)*3.667 + 7/5 = -0.8
Then the point where our points intersect is the point (3.667, 0.8)
The water treatment plant has a tank with a leak. The water tank is leaking at the rate show on the graph.
Find the rate of change at one of the two identified points
Answer:
the water is leaking at a rate of 3/4 a gallon per hour
Step-by-step explanation:
we know this because rate of change is change in y over change in x and as y goes up 3 x goes up 4 so the rate of change is 3/4

Line m passes through points (3, 15) and (10, 9). Line n passes through points (2, 9) and (9, 3). Are line m and line n parallel or perpendicular?
Answer:
The two lines 'm' and 'n' are parallel
Step-by-step explanation:
Explanation
Given that the line 'm' points (3,15) and (10,9)
The slope of the line 'm'
= [tex]\frac{y_{2} - y_{1} }{x_{2}-x_{1} } = \frac{9-15}{10-3} = \frac{-6}{7}[/tex]
Given that the line 'n' points (2,9) and (9,3)
The slope of the line 'n'
= [tex]\frac{y_{2} - y_{1} }{x_{2}-x_{1} } = \frac{3-9}{9-2} = \frac{-6}{7}[/tex]
The slope of line 'm' = The slope of line 'n'
Both slopes of the lines are equal
∴ The two lines are parallel

Answer:
22
Step-by-step explanation:
180°-90°-68°=22
in the figure below, what is m<1 if m<7= 60 dergrees
Given :
Measure of angle 7 = 60°
Angle 1 and angle 7 are corresponding angles, so their values will be equal.
Which means :
Angle 1 = 60°
Thus, the measure of angle 1 = 60°
Therefore, the correct option is (A) 60

Solve the following system of equations using the SUBSTITUTION METHOD.
SHOW YOUR WORK for full points. Write your answer as an (x,y) point.
x=4y-1
x+2y=11
Answer:
x = 7, y = 2
Step-by-step explanation:
x= 4y -1
since x is by itself 4y-1 will substitute for x in the other equation x+2y=11
it will become 4y-1+2y=11
+1 +1
add one to both sides since is doesn't have a variable.
it will become 4y+2y= 12 now add 4y+2y
becomes 6y=12
_ _
6 6
divide by 6 on each side and you get y=2.
now x=4(2)-1 you will substitute y into the first equation.
x=8-1 subtract 8 from 1 to get 7.
x=7
y=2

What is the radius of a circle that has a
circumference of 78.8 inches?
Answer:
Easy... its 39.4
Step-by-step explanation:
Cirumference is the lenght all the way around the circle
while radius is only half the circle so you just divide the cirumference by 2 to get half.
Answer:
12.54
Step-by-step explanation:
Tell whether each system of equations has no solution or ,infinitely many solutions.
Answer:
See below.
Step-by-step explanation:
x + 2 = x + 2 ⇒ Infinitely Many Solutions
3x + 1 = 3x - 10 ⇒ 1 ≠ -10 ⇒ No solutions
x + 4 = 2x + 4 ⇒ 4 = x + 4 ⇒ 0 = x ⇒ One solution
What is the center of the circle for this equation:
(x + 3)² + (y - 2)² = 25
The formula for the equation of a circle is (x - h)² + (y - k)² = r²
where (h, k) is the center of the circle and r is the radius.
So we need to find the values of (h, k) in order to find the center of the circle.
If we simply line up the equation of our given circle with our formula,
we can see that -h = 3 or h = -3 and -k = -2 so k = 2.
So now we have our answer.
center ⇒ (-3, 2)
Which of the following is the product (5y − 3)2?
A. 10y − 6
B. 25y2 − 30y + 9
C. 25y2 − 9
D. 25y2 + 30y − 9
Answer:
A
Step-by-step explanation:
distributive property
Answer:
I would say A
Step-by-step explanation:
it's A since 5y times 2 which is 10y and 3 time 2 is 6 and its still equivalent to (5y - 3) times 2 so it's 10y - 6

What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
The length of two sides are 3 and 4.
Now, We can find the third side by Pythagoras theorem, we get;
⇒ x² = 3² + 4²
⇒ x² = 9 + 16
⇒ x² = 25
⇒ x = √25
⇒ x = 5

Answer:
your question is unclear
Step-by-step explanation:
x+2y=4
-x -x
2y=4-x
divide by 2 to get y by it's self
y=2-(1/2x)

Choose the two expressions that are equivalent to 5. 75 ÷ 1. 15
A: 575 ÷115
B: 5,750 ÷ 1,150
C: 5,750 ÷ 115
D: 575 ÷ 1,150
Answer:
A and B, but I’m gonna explain it the best I can too.
Step-by-step explanation:
5.75 divided by 1.15 is the same as answer A, since all you are doing is taking away the periods, making it whole numbers.
Again 5.75 divided by 1.15 is the same as B as well, Since it is the same just without the periods and an added zero at the end of each.
This Is so that they are both all equivalent by being whole numbers, but whatever you do to one numbers in the expression that you think is the answer you have to do to the other numbers in the expression
they have to add up completely the same.
What is the slope of the line that passes through the points (-2,7) and (2, -5)?
Write your answer in simplest form.
Answer:
m=-3
Step-by-step explanation:
Answer:
-3
Step-by-step explanation:
Slope = Rise/Run
We can find the amount between 7 and -5 as 12, and -2 and 2 as 4.
Then we can do rise/run and 12/4
Which would divide into 3.
ANd because we can see the x increases as the y decreases, we can find that it's a negative slope.
