(x=3, y=8)
Step-by-step explanation:
We want to reduce as many variable as we can so, we can obtain the value for the remaining variables.
Therefore, the first equation y=x+5 multiply it -2., you have -2y=-2x-10 and sum it to the second (2y-x=13), you will obtain the following: -x=13-2x-10.
You have x=3.
If you substitute x=3 in the first equation, you have y=8
Is a triangle with side lenghts 18, 12, and 22 a right triangle?
Answer: No
Step-by-step explanation:
Pythagorean Theorem goes with a right triangle, the formula is a^2+b^2=c^2.
Let's try this out with your values.
(18*18)+(12*12) = 468
If this is true than c^2 is 468
c^2 or (22*22) is 484 is this is not a right triangle.

The midsegment is half the length of the base.
1) 32 ÷ 2 = 16
So, 16 is the midsegment
2) 11 ÷ 2 = 5.5
So, 5.5 is the midsegment
3) 32 ÷ 2 = 16
So, 16 is the midsegment
4) 14 ÷ 2 = 7
So, 7 is the midsegment
two adjacent angles form a right angle. What type of angle pair do they form?
Answer:
complementary angles
Step-by-step explanation:
Adjacent angles form a right angle.
A right angle is 90 degrees.
Two angles that add to 90 degrees are complementary.
The adjacent angles are complementary
A is directly proportional to B when A =12 and B =3
A.)find a formula for A in terms of B
B.)find the value of A when B =5
C.)find the value of B when A =36
A) To find A in terms of B, we need to find A = xB. One given is A = 12 and B = 3. We substitute, which gives us 12 = x4. Divide both sides by 4, which gives us x = 3. This means that A = 3B.
B) For this, we can just plug in 5 as B in our equation. A = 3*5 -> A = 15.
C) We can plug in A as 36. 36 = 3B -> B = 12.
A.) The formula for A in terms of B is A = 4B. B.) When B = 5, A = 20. C.) When A = 36, B = 9.
Explanation:A.) To find the formula for A in terms of B, we can set up a proportion using the given values. Since A is directly proportional to B, we can write the proportion as A/B = k, where k is the constant of proportionality. Substituting the values A = 12 and B = 3, we have 12/3 = k. Solving for k, we find k = 4. Therefore, the formula for A in terms of B is A = 4B.
B.) To find the value of A when B = 5, we can substitute B = 5 into the formula A = 4B. A = 4(5) = 20.
C.) To find the value of B when A = 36, we can rearrange the formula A = 4B to solve for B. Dividing both sides by 4, we get B = A/4. Substituting A = 36, we have B = 36/4 = 9.

Does the graph of the function y–x^2=9 intersect the following. If the answer is ‘yes’, determine the coordinates of the points of intersection the y axis
Answer:
The function intersects the y-axis at point (0.9) (vertex)
Step-by-step explanation:
we know that
The equation of a vertical parabola into vertex form is equal to
[tex]y=a(x-h)^{2}+k[/tex]
where
(h,k) is the vertex of the parabola
if a>0 then the parabola open upward (vertex is a minimum)
In this problem we have
[tex]y-x^2=9[/tex] -----> [tex]y=x^2+9[/tex]
This is a vertical parabola open upward
The vertex is the point (0,9)
The vertex is a minimum
see the attached figure to better understand the problem
The graph does not intersect the x-axis (the function has no real roots)
The function intersects the y-axis at point (0.9) (vertex)
Technician A says that the piston's most important function is to transfer the force produced by the burning air-and-fuel mixture into usable power. Technician B says that the piston size is used to help form a seal between the piston and the cylinder walls. Who is right?
A. Technician B only
B. Technician A only
C. Both Technicians A and B
Answer:
Option B.
Technician A only
Step-by-step explanation:
Since we are talking about the most important function of a piston, the technician A is correct.
A piston is used to transfer force from expanding gas in the cylinder to the crankshaft , in an engine.
In a pump, its purpose is compressing or ejecting the fluid in the cylinder.
Technician B is not correct, because piston rings are used for creating a seal between piston and cylinder walls.

Ms. Juarez earns the same amount each week as Ms. Franklin does However, Ms. Juarez only works 25 per week. How much does Ms. Juarez earn each hour. btw Ms. Franklin earns about 31,200 in a year
Answer:
he earns $24 a hour
Step-by-step explanation:
31,200 divide by 52 (that is how many weak's are in a year) = 600
600 divide by 24 = 24
:)
Ms. Juarez earns $24 per hour.
To determine how much Ms. Juarez earns each hour, we need to find her annual salary first.
Since Ms. Franklin earns $31,200 per year and Ms. Juarez earns the same amount annually, Ms. Juarez also earns $31,200 per year.
Next, we calculate the number of hours Ms. Juarez works in a year. She works 25 hours per week, and there are 52 weeks in a year:
Weekly hours x Number of weeks = Total yearly hours
25 hours/week x 52 weeks/year = 1,300 hours/year
To find her hourly wage, we divide her annual earnings by the number of hours she works in a year:
Annual salary / Total yearly hours = Hourly wage
$31,200 / 1,300 hours = $24 per hour
Therefore, Ms. Juarez earns $24 per hour.

Step-by-step explanation:
The exact form is 256/81.
For this case we have that by definition of power properties:

Answer:
m<A = 133
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary.
That means that m<A + m<C = 180.
m<A + m<C = 180
4x + 5 + x + 15 = 180
5x + 20 = 180
5x = 160
x = 32
m<A = 4x + 5
m<A = 4(32) + 5
m<A = 128 + 5
m<A = 133

Solve the system y = -x + 7 and y = 0.5(x - 3)^2
Answer:
[tex]x=-1;\ y=8\\x=5;\ y=2[/tex]
Step-by-step explanation:
You can make both equations equal and solve for the variable x, as you can see below:
[tex]-x+7=0.5(x-3)^2[/tex]
Keep on mind that:
[tex](a-b)^2=a^2-2ab+b^2[/tex]
Then:
[tex]-x+7=0.5(x-3)^2\\-x+7=0.5(x^2-2(x)(3)+3^2)\\-x+7=0.5x^{2}-3x+4.5\\0=0.5x^2-2x-2.5[/tex]
Apply the quadratic formula:
[tex]x=\frac{-b+/-\sqrt{b^2-4ac}}{2a}\\\\x=\frac{-(-2)+/-\sqrt{(-2)^2-4(0.5)(-2.5)}}{2(0.5)}\\x=-1\\x=5[/tex]
Substitute each value into one of the originl equations to find y, then:
[tex]y=-(-1)+7=8\\y=-5+7=2[/tex]

Find the lengths of AC and BD
Answer: AC = 15, BD = 7.2
Step-by-step explanation:
Use Pythagorean Theorem to solve for AC:
AB² + BC² = AC²
12² + 9² = AC²
144 + 81 = AC²
225 = AC²
√225 = √AC²
15 = AC
To solve for BD, set up a proportion using the the small side and hypotenuse of ΔABC and ΔADB.
[tex]\dfrac{s}{h}:\dfrac{9}{15}=\dfrac{BD}{12}[/tex]
[tex]\dfrac{9(12)}{15}=BD[/tex]
7.2 = BD

Find the area of a circle with a circumference of 26pi feet
Answer:
169pi feet^2.
Step-by-step explanation:
The diameter = 26pi / pi = 26 feet and the radius = 13 feet.
The area = pi r^2 = 13^2 pi

If original rect was 5 square units and if new rect is 45 square units, then
scale factor = 45/5 = 9
Answer:
The scale factor is 3
Step-by-step explanation:
The area of rectangle N is 5 units
The area of rectangle P is 45 units
Distance is times the scale factor
Area is times the scale factor squared
Volume is the scale factor cubed
Area of rectangle N * scale factor squared = Area of rectangle P
