Mathematics

Answer:

y = 6x -7

Step-by-step explanation:

1. The equation of any line in slope-intercept form is y = mx + b, where y = y-coordinate, m = slope, x = x-coordinate, and b = y-intercept.

2. Given that the slope is 6, we plug that value in m, and given that the y-intercept is -7, we plug that value in b:

y = mx + b
y = 6x - 7

The next term of the sequence is 48. (2, 4, 8, 16, 32,...)

Goryan [66]

Answer:

Step-by-step explanation:

Note that each new term of this geometric sequence is 2x the previous term.

If the sequence starts off as 2, 4, 8, 16, 32 ... , then the next term is 2(32) = 64.

(Where did the '48' come from?)

One vegetable warehouse had 210 tons of potatoes, another one had 180 tons. 90 tons of potatoes were delivered to the first and

kow [346]

Answer:

The number of days in which the amount in warehouse #2 is 1.2 greater than warehouse #1 is 6 days.

Step-by-step explanation:

Let

x: number of days

y: amount of potatoes

We can express the amount of potatoes in each warehouse using linear equations:

Warehouse #1: $y_1 = 90x+210$

Warehouse #2: $y_2 = 120x+180$

We need to find the value of x when $1.2*y_{1} =y_{2}$

Substituting the expressions for y1 and y2 in $1.2*y_{1} =y_{2}$ :

$1.2*(90x+210) =120x+180$

Applying distributive law:

$108x+252 =120x+180$

Solving the equation by subtracting 108x and 180 on both sides:

$108x+252-108x-180 =120x+180-108x-180$

$252-180 =120x-108x$

$72 =12x$

Now we divide by 12 on both sides:

$\frac{72}{12} =\frac{12x}{12}\\6=x\\x=6$

Therefore, the number of days in which the amount in warehouse #2 is 1.2 greater than warehouse #1 is 6 days.

Which expressions are equivalent to 2r + (t + r)2r+(t+r)2, r, plus, left parenthesis, t, plus, r, right parenthesis ? Choose all

Alika [10]

Answer: OPTION C.

Step-by-step explanation:

By definition, equivalent expressions have the same value but they look different.

You can obtain an equivalent expression by manipulating it algebraically.

In this case, given the following expression:

$2r + (t + r)$

You can find and equivalent expression by combining or adding the like terms (You need to remember that the like terms are those terms that have the same variable with the same exponent).

So, you can identify that like terms are:

$2r$ and $r$

Then, you can combine them by adding their coefficients (The coefficients are the numbers in front of the variable).

Therefore, you get the following equivalent expression:

$3r + t$
