Answer:

(8, -22)

Step-by-step explanation:

The tables each contain four (x,y) points of a straight line. You can see that for every increase of x by 2, y decreases by 8 in the first one (observe 26, 18, 10 2), and decreases by 6 in the second.

If you continue the table with x=4, 6 and 8, you get y=-22 in both cases for x=8. That is the intersection, so the solution is (8,-22).

Added a graph. The equations are y=10-4x and y=2-3x respectively. Hope you understand a bit of this (brief) explanation.

Ket [755]

Answer:

Paulo will need to mow at least 31 lawns to reach his goal of $2115.00.

Step-by-step explanation:

1. This is an inequality problem. The solution for this problem will involve creating in inequality to solve for the answer. To create an inequality, it is important to keep your information organized concisely.

Total = $2115.00

Lawn = $70.00

x = Amount of Lawns

2. From this information, the inequality can be formed.

70x $\geq$ 2115

3. Using the order of operations, solve the inequality.

x $\geq$ 2215/70

x $\geq$ 30.21

4. The minimum number of lawns Paulo needs to mow is 31 lawns to meet his goal of $2115.00.

Find the value of x, rounded to the nearest tenth

tatyana61 [14]

Answer:

x ≈ 8.9

Step-by-step explanation:

Given a tangent and a secant from an external point to the circle, the the square of the tangent is equal to the product of the external part of the secant and the entire secant, that is

x² = 8(8 + 2) = 8 × 10 = 80 ( take the square root of both sides )

x = $\sqrt{80}$ ≈ 8.9 ( to the nearest tenth )
