3 x − y = 8
y = x + 2
y = x + 2
y − x = 5
y − x = 5
y = 2 x − 3
y = 2 x − 3
ANSWER:
y=2x-3
HOPE IT HELPS
Step-by-step explanation:
Add the system of equations each one by one.
I added them all downwards until i found the 4th one to be correct
y = 2x - 3
y = 2x - 3
--------------
2y = 4x - 6
y = 2x - 3.
To find the value of y in each coordinates given above, substitute their respective x values.
1......y = 2(5) - 3
= 10 - 3
= 7.
2......y = 2(8) - 3
= 16 - 3
= 13.
then write the value you substituted in x on the left side of each bracket & the value you got when you substituted them on the right.

1. Baker said that she would have placed higher if she didn't have to eat blueberry pie.
2. Patrick ranked higher than Davis but lower than Natalie.
3. Coaster's father was proud of her for eating so much pie.
4. Analee ranked lower than Adams.
5. Connor did not come in 3rd.
The correct order and names are 1. Natalia Coaster, 2. Patrick Adams, 3. Analee Baker, 4. Connor Davis.
How to find the correct order?The best strategy is to read one by one the clues and determine possible order and names.
1. Statements 1 and 3 show Baker and Coaster are girls; therefore, Adams and Davis are boys.2. Statement 2 shows the order is: Natalie - Patrick - DavisSince Davis is a boy we can conclude he is Connor Davis and Patrick's last name is Adams.3. Statements 4 and 5 show Analee was the third one because otherwise Connor would be the third one and this is not true. The order is:Natalie - Patrick - Analee - Davis4. Natalie's last name is Coaster because Coaster was the girl who ate a lot of pie, while Analee did not.

Answer:
He walks 10kph.
Steps:
So he walks 1km every 0.1 hour,
1 * 10 = 10
^
(which is 1.0 hour)
Answer:
10 km/h
Step-by-step explanation:
Speed = rate at which the man walks
= distance travelled/ time taken to travel the distance.
Distance travelled = 7 kmTime took = 0.7 hoursSpeed = distance/time
= 7/0.7
= 70/7
= 10 km/h
Therefore, he walks at a speed of 10 km/h

Freezer A has interior dimensions 2 ft×2 ft×4 ft and sells for $399.99. Freezer B has interior dimensions 2.5 ft×2.5 ft×3 ft and sells for $499.99. Which freezer is a better buy in terms of dollars per cubic foot? Use pencil and paper. Show your work and explain your reasoning.
Answer:
Freezer A is a better buy in terms of dollars per cubic foot.
Step-by-step explanation:
Freezer A: V = 2*2*4 = 16 ft^3
P/V= 400/16 = 25 $/ft^3
Freezer B: V = 2.5*2.5*3 = 18.75 ft^3
P/V= 500/18.75 = 26.6 $/ft^3

A real estate agent earns a 6% commission for the sale of a home. A home sold for $350,000. What was the commission earned by the agent? $210 $2100 $21,000 $210,000.
Answer:21,000
Step-by-step explanation:
350,000 ×6/100 = 350,000×0.00.06 =21,000
The commission earned by the agent is $21,000 which is the 6% of the total selling price.
What is meant by Percentage?Percentage is defined as the parts of a number per fraction of 100. So the percentage actually means a part per 100.
Percentage is usually denoted by the symbol '%'.
We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.
Given that,
Price for which the home is sold = $350,000
Percentage as commission earned by real estate agent = 6%
Amount of commission = 6% of $350,000
= 6% × 350,000
= (6/100) × 350,000
= 0.06 × 350,000
= $21,000
Hence the commission earned by the real estate agent is $21,000.

n the rhombus m ∠ 1 = 160 ° . What are m ∠ 2 and m ∠ 3 ? The diagram is not drawn to scale
Answer:
∠ 2 = 160° , ∠ 3 = 10°
Step-by-step explanation:
The opposite angles of a rhombus are congruent , then
∠ 2 = ∠ 1 = 160°
The triangle has 2 congruent sides and is isosceles with base angles being congruent , then
∠ 3 = [tex]\frac{180-160}{2}[/tex] = [tex]\frac{20}{2}[/tex] = 10°
Answer:
m∠3 = 10° || m∠2 = 160°
Step-by-step explanation:
if m∠1 = 160°
then m∠2 = 160°
The triangle is isosceles.
therefore
m∠3 + m∠3 + 160° = 180°
2 m∠3 = 180° - 160°
2 m∠3 = 20°
m∠3 = 10°

Write an exponential function to represent a person consuming a bag of candy in which the initial value in an is 175 pieces and the rate of decay is 20%.
We will see that the exponential decay function is:
f(x) = 175*(0.8)^x
How to find the exponential decay?
The general exponential decay is:
f(x) = A*(1- r)^x
Where:
A is the initial value.r is the rate of decay in decimal form.x is the variable, in this case is the time.Here we know that the initial value is 175, and the rate of decay is 20%. To get this in decimal form, we just divide it by 100%.
20%/100% = 0.2
Replacing that in the exponential function, we get:
f(x) = 175*(1 - 0.2)^x
f(x) = 175*(0.8)^x

Let f(x)=x2 2x 3. What is the average rate of change for the quadratic function from x=−2 to x = 5? Enter your answer in the box.
The average rate of change for the quadratic function x²+2x+3 from x=−2 to x = 5 is 5.
What is Slope?A slope is also known as the gradient of a line or the average rate of change of a number that helps to know both the direction and the steepness of the line.
The rate of change of any function is the slope of the function, therefore, the slope of the function is written as,
[tex]m = \dfrac{y_2 - y_1}{x_2-x_1}[/tex]
As the value of the y is the function of the x, while the value of x is given, therefore,
[tex]x_2 = 5\\x_1=-2\\\\[/tex]
Now, the value of y,
[tex]y_2 = f(5) = x^2 +2x+3 = (5)^2+2(5)+3 = 38\\y_1 = f(-2) = x^2 +2x+3 = (-2)^2+2(-2)+3 = 3[/tex]
Substituting the value of x and y in the formula of the slope, we can write the slope as,
[tex]m = \dfrac{y_2-y_1}{x_2-x_1}\\\\m = \dfrac{f(x=5) - f(x=-2)}{5-(-2)}\\\\m = \dfrac{38-3}{7}\\\\m= 5[/tex]
Hence, the average rate of change for the quadratic function x²+2x+3 from x=−2 to x = 5 is 5.

Find the value of x.
Answer:
155°
Step-by-step explanation:
The obtuse angle of the large (outside) triangle is the supplement of 60°, so is ...
180° -60° = 120°
The angle x is the sum of the remote interior angles of that large triangle:
x = 35° +120° = 155°
__
Check
The other acute angle in the smaller (left) right triangle is 90° -35° = 55°. Then the top acute angle in the larger (bottom, right) right triangle is ...
180° -55° -60° = 65°
The other acute angle in that triangle is 90° -65° = 25°. It is supplementary to angle x. Hence angle x is 180° -25° = 155°, as above. (Note that x is also the sum of 90° and 65°, the remote interior angles of the nearest right triangle to x.)
