Answer: The correct option is

(D) $x=-4.$

Step-by-step explanation: We are given to find the equation of a vertical line passing through the point (-4, 7).

We now that

a vertical line is always parallel to the y-axis and is of the form

$x=k~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

Since the given vertical line passes through the point (-4, 7) so from equation (i), we have

$-4=k\\\\\Rightarrow k=-4.$

Substituting the value of k in equation (i), we get

$x=-4.$

Thus, the required equation of the line is $x=-4.$

Option (D) is CORRECT.

Write two equivalent fractions for the point on the number line.

navik [9.2K]

The values on the number line are between 0 and 1. There are 8 points from 0. The distance between two consecutive points would be

1/8 = 0.125

Since the given point is on the second point after 0, the equivalent value would be

2 * 1/8 = 2/8

Dividing the numerator and denominator of 2/8 by 2, we have 1/4

Thus, the two equivalent fractions for the point on number line are

2/8 and 1/4

Answer:

a. Required system of equations is:

c+p = 10

5c+4p = 46

b. 6 cakes were sold

Step-by-step explanation:

Let p be the number of pies and c be the number of cakes.

Then according to given statement " the store sold 10 baked goods"

$c+p = 10\ \ \ Eqn\ 1$

And

"A cake costs $5 and a pie costs $4"

$5c+4p = 46\ \ \ \ Eqn\ 2$

Using equation 1,

$c=10-p$

Putting this value of c in equation 2:

$5(10-p)+4p = 46\\50-5p+4p = 46\\-p = 46-50\\-p = -4\\p = 4$

Putting p = 4 in equation 1

$c+4 = 10\\c = 10-4\\c =6$

Hence,

a. Required system of equations is:

c+p = 10

5c+4p = 46

b. 6 cakes were sold
