Which values for A and B will create infinitely many solutions for this system of equations?
Answers
Answer:
A = -6; B = 15
Step-by-step explanation:
4x-Ay=15
-4x+6y=B
This is your system of equations. For it to have infinitely many solutions, the lines have to be the same. This means that if you multiply one equation by a constant, you should be able to get the other one.
With this system, you have 4x in one equation and -4x in the other. You can use this to figure out the constant. Because -4 is, well negative four, you know that the second equation is the opposite of the first; everything is multiplied by -1.
That means A = -6 and 15 = -B (The other coefficients and constants of the equations also have to be opposites.), and you can solve for B now. Divide by -1 to get B=15.

A. 26
B. 35
C. 126
R. 189
Answers
Answer:
c
Step-by-step explanation:
Answer:
ed+green+yellow=350
10% out of 350 are yellow
0.1 times 350=35
350-35=315
3/5 out of 315 are green
red is not green so
2/5 of what is left is red
2/5 of 315 is red
2/5 times 315=430/5=126
126 red

The equation of line passes through the points (0, -5) and (5, -2) will be;
⇒ y = 3x/5 - 5
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
Two points on the line are (0, -5) and (5, -2).
Now,
Since, The equation of line passes through the points (0, -5) and (5, -2).
So, We need to find the slope of the line.
Hence, Slope of the line is,
m = (y₂ - y₁) / (x₂ - x₁)
m = (- 2 - (-5)) / (5 - 0)
m = 3 / 5
m = 3/5
Thus, The equation of line with slope 3/5 is,
⇒ y - (-5)= 3/5 (x - 0)
⇒ y + 5 = 3x/5
⇒ y = 3x/5 - 5
Thus, The equation of line passes through the points (0, -5) and (5, -2) will be;
⇒ y = 3x/5 - 5

The way to get this is that you put them in fraction form 7/15 and then you make it equal to to x/100 and then divide the known part of the fraction which in this case is 100/15 which gives 6.67 (rounded). After you get that you multiply it by 7 which give you 46.69%
PLEASEEEEE HELPPPP MEEEE!!!! There are 5 friends who decide to split an 88- ounce bag of popcorn. If they split it evenly, how many ounces of popcorn will each friend get?
Solution:
Number Model:
Explain what you did with the remainder and why.
Answers
Answer:
17.6 ounces (U.S.) and or 2.2 cups (U.S.)
Step-by-step explanation:
88 ounces divided by 5 equals 17.6 ounces
88 / 5 = 17.6
The remainder can round the answer to 18 (five or more raise the score -- four or less let it rest) but the 88 ounce bag of popcorn will not be even if everyone gets 18 ounces of popcorn
If everyone were to get 18 then the bag a popcorn would have to have 90 ounces of popcorn in it
*Side note: 8 ounces is 1 cup

How many 1/4 inch cubes does it take to fill a box with width 2 3/4 inches, length 3 1/2 inches, and height 1 1/4 inches
Answers
Answer:
125 cubes brooooo gl
Step-by-step explanation:
In each side first layer for the width, 11 cubes can fit. Sine 1/4 can fit in one 4 times, 4 * 3 = 12. 12 plus 2 (2/4=1/2) is 14. So,
11 + 14 = 25.
25 is one layer. Since the height is 1 1/4 inches, multiply 25 by 5.
