Answer:
x= 1, 4
Step-by-step explanation:
[tex]log_{x+2} (9x) =2\\\\
9x = (x+2)^2 \\\\
(x+2)^2 - 9x = 0\\\\
x^2 +4x + 4-9x = 0\\\\
x^2 - 5x +4= 0\\\\
x^2 - 4x-x+4=0\\\\
x(x-4)-1(x-4)=0\\\\
(x-4)(x-1)=0\\\\
x-4 =0\: or\: x - 1=0\\\\
x = 4\: or\: x = 1\\\\
x = 1,\: 4

Which number sentence is not true?
OA) |-20| < 20
OB) |9| = 9
OC) |-20| > |9|
OD) |9|< 20
Answer:
Option A is correct option
Step-by-step explanation:
We need to find which number sentence is not true.
We will check each option.
Option A
|-20| < 20
We know that |-a|=a
20 < 20 (false)
So, this number sentence is not true.
Option B
|9| = 9
We know that |a|=a
9=9 (true)
So, this number sentence is true.
Option C
|-20|>|9|
We know that |-a|=a
20>9 (true)
So, this number sentence is true.
Option D
|9| < 20
We know that |a|=a
9<20
So, this number sentence is true.
So, Option A is correct option
im stuck on this question solve for slope and y intercept
Answer:
Slope is -2, y-intercept is 2
Step-by-step explanation:
The formula for slope is y2-y1/x2-x1, therefore:
-6-(-2)/4-2 = -4/2 = -2
As for the y-intercept, you can easily follow the pattern of the table. If y increases by 4 every time x increases by 2, you could count down (or because we're in the negatives, you'd technically count up):
-2+4 = 2

Answer:
hourly fee is $62.5
Step-by-step explanation:
75 is flat fee so it's constant. works 2 hours so flat fee time 2 is 2x.
200=75+2x
200-75=2x
125=2x
62.5=x

Answer:
angle edf is 70
Step-by-step explanation:
triangle angles always add up to 180. So if you have 40 degrees at angle e already, 180-40 = 140
since side DE and side EF are congruent, that means its an isosceles triangle. One rule for that type a triangle is that the two base angles are equal. So you can just do 140/2 = 70

Priya has a recipe for banana bread. She uses 712 cups of flour to make 3 loaves of banana bread. Andre will follow the same recipe. He will make b loaves of banana bread using f cups of flour. Which of these equations represents the relationship between b and f? Group of answer choices
Answer:
[tex]2f =5b[/tex]
Step-by-step explanation:
Given
[tex]7\frac{1}{2}\ cups = 3\ loaves[/tex]
Required
Determine the relationship between b loaves and f cups
The question shows that the relationships between cups of flour and loaves of bread is direct proportional.
So, we have:
[tex]f\ cups = b\ loaves[/tex]
and
[tex]7\frac{1}{2}\ cups = 3\ loaves[/tex]
Cross Multiply:
[tex]f * 3 = 7\frac{1}{2} * b[/tex]
[tex]3f = 7\frac{1}{2}b[/tex]
Convert fraction to improper numbers
[tex]3f = \frac{15}{2}b[/tex]
Cross Multiply
[tex]2 * 3f = 15b[/tex]
[tex]6f = 15b[/tex]
Divide through by 3
[tex]2f =5b[/tex]
Hence, the expression is: [tex]2f =5b[/tex]

Q1: Show an action-reaction pair from two objects with different masses and the resulting motion.
Q2: Show an action-reaction pair with masses of your choosing and the resulting motion.
Answer:
In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction. Thus, if the colliding objects have unequal mass, they will have unequal accelerations as a result of the contact force that results during the collision.

-23
The value of the expression after subtraction will be;
⇒ - 23
What is mean by Subtraction?
Subtraction in mathematics means that is taking something away from a group or number of objects. When you subtract, what is left in the group becomes less.
Given that;
The expression is,
⇒ (t - 8) - (t + 15)
Now,
Subtract the expression as;
⇒ (t - 8) - (t + 15)
⇒ t - 8 - t - 15
⇒ t - t - 8 - 15
⇒ - 23
Thus, The value of the expression after subtraction will be;
⇒ - 23

Triangle ABC is graphed in the coordinate plane.
Point A is located at (1, 1).
• The distance between A and B is 3 units.
• The distance between B and Cis 3 units.
Select the correct graph of AABC.
Answer:
Option C
Step-by-step explanation:
Just looking at the coordinate plane, you can count the lengths of both of the triangles: Option C’s triangle of the distance between A and B is 3 units, and the distance between B and C is also 3 units. But, Option D’s triangle has a length of 4 and 3, where the distance between A and B is 4 units, and the distance between B and C is 3 units. So choose Option C because the distance between A and B in the triangle is 3 units, and the distance between B and C in the tirangle is also 3 units.
Hope this helps and answers your question! :)
