Given that 6x – 7y=4
Find x when y = 2
Answer:
x = 3
Step-by-step explanation:
6x - 7y = 4
We are given that y = 2
6x - 7(2) = 4
6x - 14 = 4
Add 14 on both sides to leave the 6x alone
6x = 18
Divide by 6 to isolate x and find the value of x
x = 3
We can further prove this by putting in the value of x
6(3) - 7(2) = 4
18 - 14 = 4
Which is correct

Answer:
Area of larger circle = [tex]\pi *r^2=3.14(11^2)=379.94[/tex]
Area of smaller circle = [tex]\pi *r^2=3.14(3^2)=28.26[/tex]
Probability that it lands in the shaded area (smaller circle):

Step-by-step explanation:
(she has the same name as me lol)
Chloe has to pay 40$
5% of 40 is 2
20% of 40 is 8
Add the extra money together
2+8=10
Add original price
40+10=50
You get 50$ for the final price

Step-by-step explanation:
Pretend the y-axis is a wall, on the left side it is decreasing and on the right it is increasing, so A. and B. aren't correct. C. and D. are left, x<0 means on the left side of the y-axis because x (any number) is less than 0 and on the left side it is decreasing so C. isn't correct so D. is your answer because x>0 means x is greater than 0 so it's on the left side of the y-axis.

The morning temperature in Finland was −18.3∘ F. The temperature rose 23.7°F during the day before reaching its high temperature for the day.
What was the high temperature for the day?
Enter your answer in the box.
°F
Answer:
The high temperature for the day was 5.4°F
Step-by-step explanation:
-18.3 + 23.7= 5.4
The high temperature for the day is 5.4° F.
What is temperature?Temperature is a degree of hotness or coldness the can be measured using a thermometer. It's also a measure of how fast the atoms and molecules of a substance are moving. Temperature is measured in degrees on the Fahrenheit, Celsius, and Kelvin scales.
Given that, The morning temperature in Finland was -18.3° F.
The temperature rose 23.7° F during the day before reaching its high temperature for the day.
Now, -18.3°+23.7°
= 5.4° F
Therefore, the high temperature for the day is 5.4° F.

Answer:
121
Step-by-step explanation:
Since the two lines are parallel, they will have the same angles, so all we need to do is find the angle that is next to 59°. Let's label this y °.
In other words, y °, the angle next to 59°, is equal to x°.
Since we are dealing with angles of a straight line, we know that the two angles of either line will add up to be 180°.
So, 59° + y ° = 180°
Isolate y by subtracting 59 from 180.
180 - 59 = 121
y ° = 121
So, x° = 121°
The height of an experimental plant after x days can berepresented by the formula 3(4x+2). The height of a second plant can be represented by the formula 6(2x+2). Is it possible that the two plants will ever be the same height? Explain.
Answer: No
Step-by-step explanation:
The question is whether 3(4x+2) could ever equal 6(2x+2). So let's set them equal to each other and find if there is a value of x, the days, where they are equal.
3(4x+2) = 6(2x+2)
12x + 6 = 12x+2
6 = 12?? No
They will bnever be at the same height. They are growing at the same rate (12x) but starting at different heights (6 and 12)

What is the slope?
what is the y-intercept?
Proportional or not proportional?
Answer:
a) slope / m = 3
b) y-intercept / b = 0
c) Proportional
Step-by-step explanation:
a)
( y1 - y2 ) / ( x1 - x2 )
( 6 - 12 ) / ( 2 - 4 )
( -6 ) / ( -2 )
6 / 2
3
b)
y = mx + b
6 = 3(2) + b
6 = 6 + b
0 = b
c)
Proportional is when it crosses origin ( 0, 0 ).
Not proportional is when it does not cross origin.
