Shawna, Dexter, and Tilana are solving the equation Negative 2.5 (5 minus n) + 2 = 15.
Shawna says, “I can begin by dividing each side of the equation by –2.5 to get 5 minus n minus StartFraction 2 over 2.5 EndFraction = Negative StartFraction 15 over 2.5 EndFraction.”
Dexter says, “I can begin by distributing Negative 2.5 to get Negative 12.5 + 2.5 n + 2 = 15.”
Tilana says, “I can begin by multiplying each side of the equation by Negative StartFraction 1 over 2.5 EndFraction to get 5 minus n minus 0.8 = negative 6.”

Without graphing the equations, decide whether the system has one solution, no solution, or infinitely many solutions.
4y = x - 9
6x - 8y = 18
How many solutions does the system have?
A. One solution
B. Infinitely many solutions
C. No solution
Answer:
No solution
Step-by-step explanation:
Look at the first problem. As you see there is a y and a x. You cannot find x and y. So there is simply no solution.
Which transformations were used to create a triangle JKL
The transformation used to create K'L'M' would be, dilation by a scale factor 1/2 and reflection across the x-axis.
What is transformation?"Transformations are change in the original shapes on a coordinate plane by rotation, reflection or translation. "
What is reflection transformation?"It is a transformation which produces mirror image of geometrical structure."
What is dilation?"It is a transformation in which size of the geometrical structure is changed without changing its shape."
From given diagram,
we can observe that JK = 4 and J'K' = 2
This means the size of the triangle J'K'L' is reduced by 1/2
Also, it is reflected along x-axis.
This means, the transformation used to create triangle K'L'M' would be, dilation by a scale factor 1/2 and reflection across the x-axis.
Therefore, the correct answer is option (B).

Hayden had 2 1/2 gallons of water in his watering can. The seed packet said to use 1/4 of a gallon for peppers and 5/8 of a gallon for tomatoes. Hayden then used some of the water for lettuce. If Hayden had 3/4 gallons of water left over, about how much water did he use for lettuce?
i need it by 7 pm
Answer:7/4 - 7/8 = 14/8 - 7/8 = 7/8 for lettuce
Step-by-step explanation:1/4 + 5/8 = 2/8 + 5/8 = 7/8
= amount used for pepper and tomatoes
2 1/2 - 3/4 = 5/2-3/4 = 10/4 -3/4 = 7/4
= total amount used
so
7/4 - 7/8 = 14/8 - 7/8 = 7/8 for lettuce

he used 3\4 im guessing

Can someone help me put this in slope-intercept form with steps?
2x+3y = -1
Answer:
Step-by-step explanation:
basically here we wanna get y by itself
so
2x + 3y = -1
subtract 2x from both sides
3y = -2x -1
then to get y by itself we have to divide everything by 3
y = -2/3x - 1/3
this is your equation in slope intercept form
hope this helps <3

Answer:
-20
Step-by-step explanation:
5 - 25 is negative 20 and since V does not have a number attached to it you do not divide it by anything
Move the constant to the right side and change the sign

Subtract 25 from 5
