Answer:
y = -23/6
Step-by-step explanation:
1. Substitute x.
3 x -4-6y = 11
-12-6y=11
2. Solve
-12-6y=11
+12 +12
-6y= 23
y= -23/6
Step-by-step explanation:
-12-6y=11

What is the surface area of a cuboid with sides measure 7 in, 3 in and 5 in?
The surface area the cuboid is 142 inches²
The surface area of the cuboid is given as:
= 2lw + 2lh + 2hw
where, l = length
h = height
w = width
Therefore, the surface area of the cuboid given will be:
= 2lw + 2lh + 2hw
= 2(7×3) + 2(7 × 5) + 2(3 × 5)
= 2(21) + 2(35) + 2(15)
= 42in + 70in + 30in
= 142 inches²
The surface area of the cuboid is 142inches²

Jasmyn uses 42% of a gift card to buy groceries if she spent $67.20 on groceries, how much was on the gift card to begin with
Answer:
The card was worth $160.
Step-by-step explanation:
It is given that:
Percent of gift card used = 42%
Cost of groceries = $67.20
Let,
x be the total amount on gift card.
42% of x = 67.20
[tex]\frac{42}{100}x=67.20[/tex]
0.42x = 67.20
[tex]\frac{0.42x}{0.42}=\frac{67.20}{0.42}\\x=160[/tex]
Therefore,
The card was worth $160.
Rectangle A is 10 times as long as rectangle B.
If rectangle A is 80 units long, select all the ways to find the length of rectangle B. *
Answer:
Step-by-step explanation:
You will have to find what times what = 80 so 8 x 10 = 80 so the answer is 8
Answer:
Rectangle B is 8 units long.
Step-by-step explanation:
One way to Figure it out is to take 80 (rectangle A) and divide it by 10.
80/10 = 8

How do I figure out which statement is true?
Answer:
A. if table is extendedD. if only the values in the table considered.Step-by-step explanation:
We can see on the graph of g(x) that y-intercept is (0, 2)
The table doesn't have the value for x = 0 but we can observe that it is exponential function and has the formula:
f(x) = 3^xWe can find its y-intercept:
f(0) = 3^0 = 1We can compare and see that:
f(0) = 1 < g(0) = 2So the function g(x) has a greater y-intercept. This is option A.
====
Note: If only the values in the table considered, then correct option is D.

Identify the horizontal asymptote of each graph.
y = 0
y = 1
y = 6
Identify the horizontal asymptote of each graph.
y = 0
y = –3
y = –5
Answer:
y = 0 and y = -3
Step-by-step explanation:
The horizontal asymptote of each graph is:
1. y=0
2. y= -3
What is asymptote?An asymptote of a curve y = f (x) that has an infinite branch is called a line such that the distance between the point (x, f (x)) lying on the curve and the line approaches zero as the point moves along the branch to infinity.
1.Given function:
t(x)= [tex]6^{x}[/tex]
If we apply limit x→∞, then we get y=c as horizontal asymptote
So, [tex]\lim_{x \to \infty} 6^{x}[/tex]= 0
Hence, the asymptote will by y=0.
2. Given function:
t(x)= [tex]5^{x}[/tex]-3
If we apply limit x→∞, then we get y=c as horizontal asymptote
So, [tex]\lim_{x \to \infty} 5^{x} -3[/tex]= -3
Hence, the asymptote will by y=-3.

Step-by-step explanation:
First, you divide both sides by -2/5, which would get you c = 8 * -5/2 (Because when you divide, you multiply by the reciprocal). 8 * -5/2 is equal to -20. The answer is -20.

Sergio has p paintings in his art collection. He and other local painting collectors agreed to donate a total of 48 paintings to the local museum. In each of the 12 collectors will donate the same number of paintings. How many paintings will Sergio have in his art collection after his donation?
Answer:
Since there are 48 paintings being donated by 12 collectors, then we can say that each collector will donate 4 paintings.
This means that Sergio will have 4 less paintings then he had before, which was represented by pp . Thus, our expression is now \boxed{p - 4}p−4 .
Answer:
Sergio would have 4 paintings less
Step-by-step explanation:
48 total painting
12 painting collectors donated
They all donated the same amount
So each local painting collector donates the same amount of paintings
so 48 divided by 12 = 4
So each painting collector would donate 4 painting each
We don't know how much painting Sergio had in total before but we do know how much he donated which is 4

Well, the dozens of apps, spreadsheets, and other methods just don’t account for real life and all the expenses we don’t think of. There are plenty of expenses we have that aren’t monthly that take up more of our money than we planned.
