Answer:
145 cups of lemonade; 2x+1.50y=425, where y=90
Step-by-step explanation:
Let us first set up an equation, where x represents number of cups of lemonande, and y represents number of candy bars. We know that every cup of lemonade costs $2, every candy bar sold costs $1.50, and that Marcia sold a total of $425. We now have equation:
[tex]2x+1.50y=425[/tex]
However, we actually know how many candy bars Marcia sold. Therefore, our y value is 90. Let's rewrite the equation:
[tex]2x+1.50*90=425\\2x+135=425\\2x=290\\x=145[/tex]
Therefore, Marcia sold 145 cups of lemonade.
I hope this helps! Let me know if you have any questions :)

LM is the midsegment of ABC is AC is 28 centimeters long , how long is LM?
Answer:
LM = 14
Step-by-step explanation:
LM = AC/2
LM = 28/2
LM = 14
Hope this helps!
The measure of LM is 14 cm.
What is Mid - segment?A triangle midsegment is a line segment that connects the midpoints or centres of two opposite or adjacent triangle sides.
The midsegment theorem asserts that a line segment connecting the midpoints of any two sides of a triangle is parallel to and half of the third side.
According to mid segment is
LM = AC/2
We have AC = 28 cm
Now, substitute the value of AC we get
LM = 28/2
LM = 14
Thus, the measure of LM is 14 cm.

P(4)=____
X P(x)
3 0.25
4 ?
5 0.39
6 0.15
======================================================
Explanation:
All of the values in the P(x) column must add to 1.
The value 1 in probability means 100%
Let y be the missing value in the table
0.25+y+0.39+0.15 = 1
y+0.79 = 1
y = 1-0.79
y = 0.21
The probability that x = 4 is 0.21
In other words, P(4) = 0.21
Or that we have a 21% chance of having x = 4 happen.

hello guys can you help me with this?
Answer:
Step-by-step explanation:
1. Title of the graph → Comparison of the Plant Growth
2. y-axis represents the height of the plants in centimeters.
3. On day 2:
Height of plant A (plant outside) = 5.1 cm
Height of plant B (plant near the window) = 2.25 cm
4. Plant outside shows great increase in the height.
On day 5,
Height of the plant outside = 6.75 cm
Growth in height from day 2 to day 5 = 6.75 - 5.1
= 1.65 cm
Height of the plant near the window = 2.5 cm
Growth in height of the plant from day 2 to day 5 = 2.5 - 2.25
= 0.25 cm
Therefore, plant outside shows the great increase in height.
5. Plant near the window grew 0.25 cm in height.

Given the function g(x) = 6(4)x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3. Part A: Find the average rate of change of each section. (4 points) Part B: How many times greater is the average rate of change of Section B than Section A? Explain why one rate of change is greater than the other. (6 points) (10 points)
Answer:
Section A = 18
Section B = 288
Section B is 16 times greater than A
Step-by-step explanation:
Given the function :
g(x) = 6(4)^x
x = 0 to x = 1
At x = 0
g(0) = 6(4)^0 = 6(1) = 6
At x = 1
g(1) = 6(4)*1 = 24
Average rate of change for Section A = g(1) - g(0) = 24 - 6 = 18
Section B ;
x = 2 ; x = 3
g(x) = 6(4)^x
x = 2 to x = 3
At x = 2
g(0) = 6(4)^2 = 6 * 16 = 96
At x = 3
g(1) = 6(4)^3 = 6(4*4*4) = 384
Average rate of change for Section B = g(3) - g(2) = 384 - 96 = 288
Number of times B is greater than A
Section B / section A = 288 / 18 = 16 times

Write the standard equation of a circle with center (-1, 4) and radius 5
Answer:
(x + 1)² + (y - 4)² = 25
Step-by-step explanation:
The general equation for a circle is given by the formula;
x² + y² + 2hx + 2ky + c = 0 ......equation 1.
Where the center is C(-h, -k)
Also, the standard form of the equation of a circle is;
(x - h)² + (y - k)² = r² ......equation 2.
Where;
h and k represents the coordinates of the centre.
r represents the radius of the circle.
Given the following data;
h = -1
k = 4
r = 5
Substituting into eqn 2, we have;
(x - {-1})² + (y - 4)² = 5²
Simplifying further, we have;
(x + 1)² + (y - 4)² = 25

In the equation 2x+4=y, what is the value of y when x=5?
9514 1404 393
Answer:
y = 14
Step-by-step explanation:
Put the value of x where x is and do the arithmetic.
2x + 4 = y
2·5 + 4 = y . . . . . . substitute for x
10 + 4 = y . . . . . . . multiply
14 = y . . . . . . . . . . add
The value of y is 14 when x = 5.
(PLEASE HELP I JUST WANNA KNOW HOW TO DO IT WILL GIVE REWARDS.) Show all work to solve the equation for x. If a solution is extraneous, be sure to identify it in your final answer.
square root of the quantity x minus 2 end quantity plus 8 equals x
