Y=4x-11. 4x-y=11. solving systems of equations using substitution​

Mathematics
1 answer:
Black_prince [1.1K]2 years ago
3 0

Answer:

infinite number of solutions

Step-by-step explanation:

y = 4x - 11 → (1)

4x - y = 11 → (2)

Substitute y = 4x - 11 into (2)

4x - (4x - 11) = 11  ← distribute parenthesis on left side

4x - 4x + 11 = 11 ( subtract 11 from both sides )

0 = 0 ← true statement

This indicates the system has an infinite number of solutions

]solomon needs to justify the formula for the arc length of a sector. which expression best completes this argument? the circumf
Anna35 [415]

Answer:

\frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}} best completes this argument

Step-by-step explanation:

Circumference of circle =\pi \cdot d

Where d is the diameter of circle

We are given that if equally sized central angles, each with a measure of n°, are drawn, the number of sectors that are formed will be equal to \frac{360^{\circ}}{n^{\circ}}

So, Number of sectors =  \frac{360^{\circ}}{n^{\circ}}

The arc length of each sector is the circumference divided by the number of sectors

\Rightarrow \frac{\pi \cdot d}{\frac{360^{\circ}}{n^{\circ}}}

Diameter d = 2r (r = radius)

\Rightarrow \frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}}

Option b is true

Hence\frac{2 \pi r}{\frac{360^{\circ}}{n^{\circ}}} best completes this argument

Complete the input-output table for linear function y=3x
Veseljchak [2.6K]

The input and output table for the linear function y = 3x is (-2, -6), (-1, -3), (0, 0), (1, 3) and (2, 6).

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Given the linear function y = 3x:

When x = -2; y = 3(-2) = -6

When x = -1; y = 3(-1) = -3

When x = 0; y = 3(0) = 0

When x = 1; y = 3(1) = 3

When x = 2; y = 3(2) = 6

The input and output table for the linear function y = 3x is (-2, -6), (-1, -3), (0, 0), (1, 3) and (2, 6).
