explain why 4/9-d^2/25=0 has no real solutions
Answer:
The solution x = 0 means that the value 0 satisfies the equation, so there is a solution. “No solution” means that there is no value, not even 0, which would satisfy the equation.

3 friends went to lunch and total was $38.49. how much would it have cost 7 friends
Answer:
89.81
Step-by-step explanation:
divide 38.49 by 3 and you get 12.83
then multiply 12.83 by 7
Answer:
Step-by-step explanation:
Cost of lunch for 3 persons = $ 38.49
Cost of lunch for 1 person = 38.49 ÷ 3 = $ 12.83
Cost of lunch for 7 persons = 12.83 * 7 = $ 89.81

Explanation:
y = mx + b Calculate the slope, m, from the given point values, solve for b by using one of the point values, and check your solution using the other point values.
A line can be thought of as the ratio of the change between horizontal (x) and vertical (y) positions. Thus, for any two points defined by Cartesian (planar) coordinates such as those given in this problem, you simply set up the two changes (differences) and then make the ratio to obtain the slope, m.

for the slope, m.
A line has the general form of y = mx + b, or vertical position is the product of the slope and horizontal position, x, plus the point where the line crosses (intercepts) the x-axis (the line where z is always zero.) So, once you have calculated the slope you can put any of the two points known into the equation, leaving us with only the intercept 'b' unknown.

Nayeli is saving up to buy a new video game she already has $15 and can save an additional five dollars per week using money from afterschool job how much total money would Nayeli have after six weeks of saving also write expression that represents the amount of money Nayeli would have saved in W weeks
Answer:
5w + 15
$45
Step-by-step explanation:
(6)*(5) + 15 = $45
The amount of money Nayeli would have saved in W weeks is given by the equation A = 5W + 15
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
After one week of saving, Nayeli will have:
$15 + $5 = $20
After two weeks of saving, Nayeli will have:
$20 + $5 = $25
Continuing this pattern, we can find that after six weeks of saving, Nayeli will have:
$15 + 6($5) = $45
So, after six weeks of saving, Nayeli will have $45.
Amount saved = starting amount + (amount saved per week) × (number of weeks)
Amount saved = $15 + ($5)W be equation (1)
So, the expression that represents the amount of money Nayeli would have saved in W weeks is
A = $15 + ($5) W
Hence , the equation is A = 5W + 15

write the equation parallel to the line 3y = 2x - 5 that goes through the point (6,5)
Answer:
3y = 2x + 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3y = 2x - 5 ( divide terms by 3 )
y = [tex]\frac{2}{3}[/tex] x - [tex]\frac{5}{3}[/tex] ← in slope- intercept form
with slope m = [tex]\frac{2}{3}[/tex]
Parallel lines have equal slopes , then
y = [tex]\frac{2}{3}[/tex] x + c ← is the partial equation
To find c substitute (6, 5 ) into the partial equation
5 = 4 + c ⇒ c = 5 - 4 = 1
y = [tex]\frac{2}{3}[/tex] x + 1 ( multiply through by 3 to clear the fraction )
3y = 2x + 3 ← equation of parallel line

The ratio of the length and breadth of a badminton court is 11:5. If the length of the court is 44 feet, then what is its breadth? help please! I need it!
Answer:
20ft
Step-by-step explanation:
Quick reasoning: pick the ratio and start adding both values as many times as you reach the value you need: You start with 11:5, add once, you get 22:10; add again, you get 33:15. Add one final time, you get 44:20.
More rigorous: You want to see how many times the length fit in the ratio: that means dividing the length by the first term of the ratio, or 44/11 = 4. At this point you multiply the second term by the number you just found, ie 5x4= 20.
