When x=4

1. Substitute the x into the equation.

y=3(4)+10

2. Solve for y

y=3(4)+10

y=12+10

y=22

When x=5

1. Substitute the x into the equation.

y=3(5)+10

2. Solve for y

y=3(5)+10

y=15+10

y=25

When x=6

1. Substitute the x into the equation.

y=3(6)+10

2. Solve for y

y=3(6)+10

y=18+10

y=28

Answer:

1497 - 202

Step-by-step explanation:

The question is saying that the Las Vegas trip was longer so we know to put that first in the expression

we can also tell that the question is asking us for the difference (aka subtraction) between the two trip by the key words how much longer

and then it tells us that we are finding the difference between Las Vegas and Cheyenne so we know to use those two numbers

that is how we come up with the expression 1497 - 202

frez [133]

Answer:

8 dimes
5 quarters

Step-by-step explanation:

If all were dimes, the total would be $1.30. It is $0.75 more than that.

Each quarter that replaces a dime adds $0.15 to the total, so there must be ...

$0.75/$0.15 = 5

quarters.

Kevin has 8 dimes and 5 quarters in change.

_____

Check

8 × 0.10 + 5 × 0.25 = 0.80 + 1.25 = 2.05 . . . . answer checks OK

Answer:

Let's see what to do buddy..

Step-by-step explanation:

_________________________________

STEP (1)

We know that the quadratic functions form are like this :

$y = a \: {x}^{2} + b \: x + c$

The quadratic function opens upward so ;

$a > 0$

The axis of parabolic symmetry passes through the vertex of the parabolic.

So we know that x vertex is equal to -2.

The vertex's x is finding from this equation:

$x = - \frac{b}{2a} \\$

So we have :

$- 2 = - \frac{b}{2a} \\$

Multiply the sides of the equation by 2a :

$b = 4a$

_________________________________

STEP (2)

A quota passes through points (-3,2) and (0,11) , so points (-3,2) and (0,11) must be true in the quota equation.

$y = f(x) = a{x}^{2} + bx + c \\ \\b = 4a \\ \\ y = f(x) = a {x}^{2} + 4ax + c$

$f( - 3) = 2 \\ \\ a ({ - 3})^{2} + 4a( - 3) + c = 2 \\ \\ 9a - 12a + c = 2 \\ \\ - 3a + c = 2 \\ \\ \\ \\ f(0) = 11 \\ \\ a ({0})^{2} + 4a(0) + c = 11 \\ \\ c = 11$

$- 3a + c = 2 \\ \\ c = 11 \\ \\ - 3a + 11 = 2 \\ 11 \: goes \: to \: the \: other \: side \: \\ \\ - 3a = 2 - 11 \\ - 3a = - 9 \\ divided \: the \: sides \: of \: the \: equation \: by \: - 3 \\ a = 3$

And we're done.

Thanks for watching buddy good luck.
