Answer:

x = - 11

Step-by-step explanation:

3(x + 5) = x - 7

3x + 15 = x - 7

2x  = -7 - 15

2x = - 22

x = - 11

Answer:

-20

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.

A realistic budget is hard to come by. All budgets tell you what you should include in your monthly plan, but what about unexpected expenses? Here are some ideas for making a realistic budget, and sticking to it.

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.

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

Answer:

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:

We can find its y-intercept:

We can compare and see that:

So 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.

Answer:

y = 0 and y = -3

Step-by-step explanation:

The horizontal asymptote of each graph is:

1. y=0

2. y= -3

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.

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:

Answer:

168 in

Step-by-step explanation:

Pythagoras says:

b² + 56² = 70²

so

b² = 70² - 56²

b = √1764 = 42

so the perimeter is 70+56+42 = 168

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.

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
