Using a system of equations, it is found that the numbers are 5 and -7.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, we say that the numbers are x and y.

They multiply to -35, hence:

xy = -35.

They add to -2, hence:

x + y = -2 -> y = -2 - x

Replacing on the first equation:

x(-2 - x) = -35

-x² - 2x + 35 = 0

x² + 2x - 35 = 0

(x + 7)(x - 5) = 0

x = -7 -> y = 5

x = 5 -> y = -7

Hence the numbers are 5 and -7.

Answer:

Step-by-step explanation:

The picture is a bit blurry, but from what i can see, i'd say C (whichever one has -4 x 3 x 1 under the square root.)

So for this, you need to know the quadratic formula, which is:

$\frac{-b ± \sqrt{b^{2} -4ac} }{2a}$

*ignore the weird capital A, it keeps coming up when i try to use the ± symbol

They have given you the equation of a quadratic, so the first thing you have to do is rearrange it, so that $x^{2}$ comes first.

So now we have the equation: 3 $x^{2}$  - 2x +1

*the quadratic formula uses a, b and c, but they are specific. a is always the coefficient of $x^{2}$ , b is always the coefficient of x and c is always the constant (number without an x)

So, i can find that, in this case:

a = 3 b= -2 c=1

Now substitute each of those values it into the original quadratic equation:

$\frac{-(-2) ± \sqrt{(-2)^{2} -4(3)(1)} }{2(3)}$

*again, ignore the weird capital A.

That's how you find the answer, which from what i can tell in the picture is C.

Hope that helped : )

The expression that represents the amount mother spent is 4 × 5.00 + 2.00.

This outing will cost $22.00.

Solution:

Number of members in a family = 4

Cost of one ticket = $5.00

Cost of soft drink = $2.00

Mother spent = Number of members × Cost of each ticket + Cost of soft drink

= 4 × 5.00 + 2.00

The expression that represents the amount mother spent is 4 × 5.00 + 2.00.

To solve this expression using PEDMAS rule.

First do multiplication.

4 × 5.00 + 2.00 = 20.00 + 2.00

Now do addition.

4 × 5.00 + 2.00 = 22.00

Hence this outing will cost $22.00.
