Which graph represents -3x + 5y = -15
Answers
Answer:
B
Step-by-step explanation:
The y intercept is -3 because -15/5=-3
The obtained coordinates are matching with graph B. Therefore, option B is the correct answer.
The given equation is -3x + 5y = -15.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Rearrange the given equation that is 5y = -15+3x
y= 3/5 x - 3
Put x=0, y=0-3
y=-3
Put x=5, y=3-3
y=0
Now, the coordinates to plot graph are (0, -3) and (5, 0).
The obtained coordinates are matching with graph B. Therefore, option B is the correct answer.

Answers
Answer:
x = 4, x ≠ -1
Step-by-step explanation:
√3x + 4 = x
(√3x + 4)² = x² (Square both sides to get rid of the radical.)
3x + 4 = x²
0 = x² - 3x - 4 (Set everything to 0 by moving everything to one side.)
0 = (x - 4)(x + 1) (Factor.)
x = 4 x = -1
Now we need to check for extraneous solutions:
√3(4) + 4 = 4
√12 + 4 = 4
√16 = 4
4 = 4
√3(-1) + 4 = -1
√-3 +4 = -1
√1 = -1
1 ≠ -1
-1 is an extraneous solution.

digital piano is 54 inches. Will it fit along the
wall next to the bookshelf? Explain your answer.
please help!!
explain good and clearly:) I’ll give you brainliest!!
Answers
*see attachment for the drawing
Answer:
No. The width is longer than the space available along the wall next to the bookshelf.
Step-by-step explanation:
The scale of the length of the space the piano is to occupy along the wall close to the bookshelf = 12 cm - 4 cm = 8 cm
Actual length of the space given a scale of 1 cm to 6 in: 6*8 = 48 in
The piano is said to have a width of 54 inches, therefore, it will not fit along the wall next to the bookshelf. The space available along the bookshelf is just only 48 inches long, which is less than the width of the piano.
Answer:
No
Step-by-step explanation:

Heather made $299 for 13 hours of work.
At the same rate, how much would she make for 18 hours of work?
Answers
Answer:
$414
Step-by-step explanation:
We know that Heather made $299 for 13 hours of work.
So, to find how much Heather will make for 18 hours of work at the same rate, we can write and solve for the following proportion:
[tex]\frac{299}{13}=\frac{x}{18}[/tex]
Notice that we align the rates vertically and the measurements horizontally (dollars in the numerator and hours in the denominator).
So, to find how much Heather will make for 18 hours, we will solve for x. Cross-multiply:
[tex]13x=5382[/tex]
Divide both sides by 13:
[tex]x=\$414[/tex]
So, Heather will make $414 for 18 hours of work.
And we're done!
If Ryan gives 4/9 of his 36 cards to Josiah, how many cards does he give Josiah?
Answers
Answer:
16 cards
Step-by-step explanation:
Answer:
Ryan gave 16 cards to Josiah.
Step-by-step explanation:
First we will divide 36 by 9.
36/9 = 4
We know that 1/9 of 36 is 4.
1/9 + 1/9 + 1/9 + 1/9 = ?
4 + 4 + 4+ 4 = ?
4 * 4 = 16
4/9= 16
Ryan gave 16 cards to Josiah.
Luke opened a savings account with a balance of $0.00 and deposited $20.00. During the next 2 weeks, he made two more deposits for $15.00 and $35.00. At the end of the month, he made a withdrawal that brought his balance back to $0.00. Assuming no interest was earned, how much money did Luke withdraw from his savings account?
Answers
Answer:
85$ was withdrawed.
Step-by-step explanation:
20 + 30 + 35 = 85 - 85 = 0
Answer:
Okays so Luke deposited $20.00, $15.00, and $35.00 so we can make the equation
$20.00 + $15.00 + $35.00 = $70.00
At the end of the month he withdrawaled all of his money which brought it back to $0.00. That means that Luke withdrawled $70.00 from his bank account!

Please answer x as a fraction
Answers
Answer:
x = -4 2/13
x = -4.15384615385
x = -54/13
(they are all the same, just in different formats)
Step-by-step explanation:
(5/3x) + 6 = (2/9)x
first, make all "x"s have a common denominator
(5/3) = (15/9)
so
(5/3)x = (15/9)x
(15/9)x + 6 = (2/9)x
solve using inverse operations
(15/9)x + 6 = (2/9)x
-(2/9)x -(2/9)x
(13/9)x + 6 = 0
-6 -6
(13/9)x = -6
to get rid of the fraction, multiply the entire equation by the denominator
(13/9)x = -6
*9 *9
13x = -54
/13 /13
x = -4 2/13
x = -4.15384615385
x = -54/13
(they are all the same, just in different formats)
