Answer:

B and E

Step-by-step explanation:

2x²-7x+3=0

2x²-x-6x-3=0

x(2x-1)-3(2x-1)=0

(x-3)(2x-1)=0

x=3 or x=1/2

Answer:

Step-by-step explanation:

$9\frac{1}{8} = 2\frac{1}{4} +x$

$\frac{9*8+1}{8} =\frac{4*2+1}{4} +x$

$\frac{73}{8} =\frac{9}{4} +x$

$\frac{73}{8} =\frac{9+4*x}{4}$

do cross multiplication

$8(4x+9)=4*73\\32x+72=292\\32x=292-72\\x=220/32\\x=6.875$

Ethan went to the grocery store and bought bottles of soda and bottles of juice. Each bottle of soda has 45 grams of sugar and e

Anna35 [415]

9 bottles of soda and 10 juice bottles are purchased

Solution:

Given that,

Sugar contained by each soda bottle = 45 grams

Sugar contained by each juice bottle = 35 grams

Let,

x be the number of soda bottles

y be the number of juice bottles

Given that,

Ethan purchased a total of 19 bottles of juice

Therefore, we get,

x + y = 19 ---------- eqn 1

Ethan purchased a total of 19 bottles of juice and soda which collectively contain 755 grams of sugar

Therefore, we frame a equation as:

$45 \times x + 35 \times y = 755$

45x + 35y = 755 --------- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

x = 19 - y --------- eqn 3

Substitute eqn 3 in eqn 2

45(19 - y) + 35y = 755

855 - 45y + 35y = 755

10y = 100

y = 10

Substitute y = 10 in eqn 3

x = 19 - 10

x = 9

Thus 9 bottles of soda and 10 juice bottles are purchased

The graphs of quadrilateral LMNO and its image are shown below.

REY [17]

You can use the ordered pairs to describe the translation that took place.

If you choose any vertex, you can use that to describe the translation that occurred with all vertices.

I'll look at N. Vertex N moved to the right 5 and up 7.

You can use the beginning and ending ordered pairs to see these distances.

Start: (-1, -1)
End: (4, 6)

-1 to 4 is 5 units
-1 to 6 is 7 units

Answer: THIRD OPTION.

Step-by-step explanation:

The slope can found by using the following formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

In this case, in order to find the slope of the given function, we need to choose two points from the table provided in the exercise. Let's choose these points:

$(-2,-2)\\\\(2,10)$

We can identify that:

$y_2=-2\\y_1=10\\\\x_2=-2\\x_1=2$

Substituting these values into the formula, we get that the slope of the function is:

$m=\frac{-2-10}{-2-2}\\\\m=3$

This matches with the third option.
