Answer:

Step-by-step explanation:

You can solve 6a + 6c =126 for either a or c, but until you have a second equation in either a or c or both, you cannot find the values of a and c.

6a + 6c =126 reduces to 6(a + c = 23), or just a + c = 23. Then either a = 23 - c or c = 23 - a, but we cannot find a or c as a specific numeric value.

What is a linear equation in math?

A linear equation only has one or two variables. No variable in a linear equation is raised to a power greater than 1 or used as the denominator of a fraction.
When you find pairs of values that make a linear equation true and plot those pairs on a coordinate grid, all of the points lie on the same line.
There are three major forms of linear equations: point-slope form, standard form, and slope-intercept form. We review all three in this article.
Some of the examples of linear equations are 2x – 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, 3x – y + z = 3.

$\frac{3^{2} * 3^{-5} }{4^{2} } = \frac{3^{-3} }{4^{-2} }$

$\frac{1}{3^{3} }$ ÷ $\frac{1}{4^{2} }$

$\frac{1}{27} * 16 = \frac{16}{27}$

Answer:

A. Plant 1 is growing at a faster rate than Plant 2.

Step-by-step explanation:

The slope (m) or rate of growth in Plant 1 is;

m = Change in y ÷ change in x

m = $\frac{3.5 - 1.5}{1 - 0}$ = 2

The linear equation of growth in Plant 1 is;

$\frac{y - 1.5}{x - 0}$ = 2

y = 2x + 1.5

The equation of growth in Plant 2 is; y = 1.5x + 3 (slope of 1.5)

Since the slope in growth of Plant 1 is greater than that in Plant 2, it implies then that Plant 1 is growing at a faster rate than Plant 2.

Answer:

x = 2

Step-by-step explanation:

By the property of intersecting chords outside of the circle.

$EC \times ED = EB \times EA \\ (x + 4)(x + 4 + 1) = (x + 1)(x + 1 + 11) \\ (x + 4)(x + 5) = (x + 1)(x + 12) \\ {x}^{2} + (4 + 5)x + 20 = {x}^{2} + (1 + 12)x + 12 \\ 9x + 20 = 13x + 12 \\ 9x - 13x = 12 - 20 \\ - 4x = - 8 \\ x = \frac{ - 8}{ - 4} \\ \huge \red{ \boxed{x = 2}}$
