The type and number of solutions is (b) two imaginary solutions.

<h3>How to determine the type and number of solutions?</h3>

The equation is given as:

3x² + 5x + 5 = 0

A quadratic equation can be represented as:

ax^2 + bx + c = 0

Where, the discriminant (d) is

d = b^2 - 4ac

So, we have

d = 5^2 - 4 * 3 * 5

Evaluate

d = -35

The value of d is negative

This means that the equation has only imaginary solutions

Hence, the type and number of solutions is (b) two imaginary solutions.

What line would be parallel to 8x-2y=7 with a point of 12,1

SOVA2 [1]

Answer:

$y = 4x - 47$

Step-by-step explanation:

Equation of a line:

The equation of a line has the following format:

$y = mx + b$

In which m is the slope and b is the y-intercept.

Parallel lines:

When two lines are parallel, they have the same slope.

8x-2y=7

Placing into the format, we have thtt:

$2y = 8x - 7$

$y = 4x - \frac{7}{2}$

Slope of 4.

This means that the desired line has the following equation:

$y = 4x + b$

Point of (12,1)

This means that when $x = 12, y = 1$

We use this to find b.

$y = 4x + b$

$1 = 48 + b$

$b = -47$

So, the line has the equation:

$y = 4x - 47$

PLEASE What fraction of 9 3/8 is 4 3/8 ? (A) 3/8 (B) 7/15 (C) 5/9 (D) 315/8

sattari [20]

Hello!

To solve this, I would convert to improper fractions. This is done by multiplying the integer with the denominator and adding it to the numerator.

9 3/8: 9*8+3=72+3=75

4 3/8: 4*8+3=32+3=35

So the improper fractions therefore are 75/8 and 35/8.

Now to see what fractions of each other they are, you can just divide the numerators because the denominators cancel each other out.

35/75 = 7/15

So your answer would be 7/15, or B.

Hope this helped!
