Step-by-step explanation:
2.3r - 7 + 6 = 21
2.3r - 1 = 21
2.3r = 22
r = 22/2.3
r = 9.6
2.3(4.23) - y + 6 = 21
9.73 - y + 6 = 21
15.73 - y = 21
-y = 5.27
y = -5.27
simplify by using order of operations 10/2 + 3 + 6 + 3/3
Answer:
15
Step-by-step explanation:
Order of operations: Parentheses, Exponents, Multiplication, Division, Addition/Subtraction
We'll start with division first. 10/2 = 5, 3/3 = 1
Then, we'll add the terms left. 5 + 3 + 6 + 1 = 15
if a polygon is a triangle, then it has exactly three sides. is the converse of the conditional true?
Answer:
If a polygon is a triangle then it has exactly three sides
A polygon has 3 sides if and only if it is a triangle. Put it all together: Conditional: If a polygon is a triangle, then it has three sides. Converse: If a polygon has three sides, then it is a triangle.
Answer:
yes
Step-by-step explanation:
because the polygon it has tree sides it's called triangle hope it's helppls help! i’ll mark brainlest :)

Step-by-step explanation:
f(x) = 3x + 2
What is f(5)?
Hello!
f(x) = 3x + 2
Since you are provided with f(5), we will replace every "x" in the equation with the number 5.
f(5) = 3(5) + 2
f(5) = 15 + 2
f(5) = 17
I hope this helps you! Have a great day!

Which statement correctly describes the inverse of the following function?
Ingrid and Harish were trying to solve the equation:
22 - 3x = x + 1
Ingrid said, "First, I'll subtract x from both sides so I have a? - 4x = 1. Then I can solve by completing the
square. If I add 4 to each side, I can rewrite the equation as (x - 2)² = 5."
Harish said, “I'll isolate the xạ term by adding 3x to both sides of the equation. Then I'll solve by taking the
square root."
Whose solution strategy would work?
Answer:
Only Ingrid's equation is correct
Answer:
Only Ingrid’s solution works
Which of the following is a solution of the equation 9- 2x=-1?
04
05
04
0-5
Answer:
the answer is 5
Step-by-step explanation:
9-2x=-1. you subtract the 9 from both sides, giving you -2x=-10. then you divide the -10 by -2 which gives you 5
what is the equation of the line that passes through (6,4) and (4,1)
Answer:
y = 3/2*x - 5
Step-by-step explanation:
Lets say that P1=(6,4) and P2=(4,1) and that the form of the equation must be y=m*x+b where m is the slope and b the independent variable. Then having two given points we can use the slope formula to find the slope value as:
P1=(x1,y1) and P2=(x2,y2)
slope formula ---> m=(y2-y1)/(x2-x1)
Replacing the given points ---> m=(1-4)/(4-6) = 3/2
then replacing the slope value obtained:
y = 3/2*x + b
Now lets find the value of b. For this we have to replace in the equation a point it can be P1 or P2, i will replace P2:
1 = 3/2*4 + b
1 = 6 + b
1 - 6 = b
-5 = b
therefore the line equation is:
y = 3/2*x - 5

What is the equation in slope intercept form of the line that has a slope of -8 and y-intercept of 4/5?
Answer:
y=-8x+4/5
Step-by-step explanation:
the formula for slope intercept is y=mx+b so you just plug in the numbers. m is slope and b is the y intercept
sorry if this is wrong :)
Answer:
The answer will be listed below!
Step-by-step explanation:
The equation would be y=-8x+4/5. Slope intercept form is y=mx+b. m would be the slope while b is the y-intercept so in the end, you get y=-8x+4/5.

How many degrees is the measurement of the missing angle? (Only numeric answer, no words or symbols at all)
Answer:
65°
Step-by-step explanation:
35° + 80° + x° = 180°
115° + x = 180°
x = 180° - 115°
x = 65°

Can someone pls help me?!?
Answer:
Step-by-step explanation:
If the sum of the two given angles is 5 + 10 = 15 then the third side cannot be larger than 15. If it is, the two given angles will fall flat on the third angle.
If the third angle is less than 5 then the sum will be less than 10 and the same thing will happen as described above.
So the correct answer is B
Which is a better deal?
An ice company charged $6.02 for 7 bags of ice. If a
convenience store sold 6 bags of ice for $5.52, which is a
better buy?
Explain/Justify your answer
Answer:
The $6.03 for 7 bags of ice is a better deal
Step-by-step explanation:
In order to find out which is a better deal we find the unit price.
To find the unit price we do the cost divided by how many bags of ice.
6.02 divided by 7 = 0.86, so the unit price is 0.86/1
5.52 divided by 6 = 0.92, so the unit price is 0.92/1
Finally, we can see which has a lower unit price which is the $6.03 for 7 bags of ice
