Answer:
9a to the power 2 +4 is the answer
Step-by-step explanation:
multiple 3a x 3a u wud get 9a to the power 2
-2 x -2 u wud get = 4
then combine the two and write the answer
Answer:
9a² - 12a + 4
Step-by-step explanation:
Given
(3a - 2)(3a - 2)
Each term in the second factor is multiplied by each term in the first factor, that is
3a(3a - 2) - 2(3a - 2) ← distribute both parenthesis
= 9a² - 6a - 6a + 4 ← collect like terms
= 9a² - 12a + 4
he heat in the house is set to keep the minimum and maximum temperatures (in degrees Fahrenheit) according to the equation |x – 72.5| = 4. What are the minimum and maximum temperatures in the house? 72.5°F and 76.5°F 68.5°F and 76.5°F 70.5°F and 74.5°F 72.5°F and 74.5°F
Answer:
B. 68.5 & 76.5
Step-by-step explanation:
In order to solve this equation you first need to change your equasion to fit 2 scenarios. So, your 2 equations are x-72.5=4 and x-72.5=-4. From there, you need to solve by adding 72.5 to each equation giving you x=76.5 and x=68.5. 68.5 degrees F is your minimum temperature and 76.5 degrees F is your maximum temperature. I have included a screenshot of my handwritten work included below for those who are visual learners.
1) Solve the equation 7x+5 = 7x-3
Answer: no solutions
7x + 5 = 7x - 3
5 = -3 [ subtract 7x from both sides ]
Since we end up with 5 = -3, a clearly false equation, we conclude that the original equation has no solutions.
i hope this helps! :D
Answer:
empty set
Step-by-step explanation:
Let's solve your equation step-by-step:
7x+5=7x−3
Step 1: Subtract 7x from both sides.
7x+5−7x=7x−3−7x
5=−3
Step 2: Subtract 5 from both sides.
5−5=−3−5
0=−8
So that There is no solution.( empty set .∅)

The graph shows a line and two similar triangles. On a coordinate plane, a line goes through (0, 3) and (6, 11). A small triangle has a rise of 4 and run of 3. What is the equation of the line? y = 3 x + 3 y = three-fourths x + 3 y = four-thirds x + 3 y = 4 x + 3
Answer:
i think that the answer is the first equation
Step-by-step explanation:
The equation of the line passing through the points (0, 3) and (6, 11) is:
y = (4/3)x + 3.
Option C is the correct answer.
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
To find the equation of the line passing through the points (0, 3) and (6, 11).
We can use the slope-intercept form of a linear equation,
which is y = mx + b, where m is the slope of the line and b is the y-intercept.
First, we can find the slope of the line by using the formula:
[tex]m = (y_2 - y_1) / (x_2 - x_1)[/tex]
where
[tex](x_1, y_1) = (0, 3)\\(x_2, y_2) = (6, 11).[/tex]
So,
m = (11 - 3) / (6 - 0) = 8/6 = 4/3
The slope of the line is 4/3.
Next,
We can use the point-slope form of a linear equation to write the equation of the line in terms of one of the points and the slope:
[tex]y - y_1 = m(x - x_1)[/tex]
Choosing the point (0, 3), we get:
y - 3 = (4/3)(x - 0)
Simplifying and solving for y, we get:
y = (4/3)x + 3
Therefore,
The equation of the line passing through the points (0, 3) and (6, 11) is:
y = (4/3)x + 3.

What is the point-slope form of an equation passing through (0, -5) with a 5 points
slope of 2? *
Answer:
y=2x-5
Step-by-step explanation:
[tex]y-y_{1}=m(x-x_{1})[/tex]
[tex]x_{1}=0, y_{1}=-5\\[/tex], and m=2
[tex]y-(-5)=2(x-0)[/tex], -(-5)-Two negatives make it positive, and you distribute the 2
[tex]y+5=2x[/tex], you now subtract 5 to get y by itself to get your answer of
[tex]y=2x-5[/tex]
*NOTE* (0,-5) is the y-intercept, so you could have used the linear equation of y=mx+b, m=2, and b(y-intercept)=-5
giving you y=2x-5

Step-by-step explanation:

measure of angle D: 6(6) + 8 = 44
measure of angle C: 180 - 82 = 98
check answers by adding all 3 angle measures to make sure they equal 180 degrees
can anyone help me ?
Answer: m∠T = 48°
ΔMAT has MA = MT
=> ΔMAT is a isosceles triangle at M
=> ∠A = ∠T = (180° - ∠M)/2
=> x + 20 = (180 - 3x)/2
⇔ 2x + 40 = 180 - 3x
⇔ 5x = 140
⇔ x = 140/5
⇔ x = 28
=> ∠A = ∠T = 28 + 20 = 48°

2 Hiroaki says that a constant of proportionality must be a whole number and
cannot be a fraction or a decimal. Explain why Hiroaki is incorrect.
Given:
Hiroaki says that a constant of proportionality must be a whole number and cannot be a fraction or a decimal.
To find:
The explanation, why Hiroaki is incorrect.
Solution:
If y is directly proportional to x, then
[tex]y\propto x[/tex]
[tex]y=kx[/tex]
[tex]\dfrac{y}{x}=k[/tex]
where, k is the constant of proportionality.
It means, the constant of proportionality is the ratio of two directly proportional variables.
So, constant of proportionality can be any real.
Thus, the statement that a constant of proportionality must be a whole number and cannot be a fraction or a decimal is incorrect.
Hence, Hiroaki is incorrect because constant of proportionality can be any real.
