Does the system shown always, sometimes, or never have a solution when a > b?

AysviL [449]

Answer:

always have a solution

Step-by-step explanation:

A linear equation in standard form is given by:

Ax + By = C, where A,B, C are real numbers and A,B is not equal to zero.

Two linear equations with equations Ax + By = C and Dx + Ey = F

Therefore the first equation becomes: (A/B)x + y = C/B and the second equation becomes (D/E)x + y = F/E ]

Both equations are said have a solution if A/B ≠ D/E, they have no solution if A/B = D/E and they have infinite solutions if A/B = D/E, C/B = F/E.

Given that:

when a > b

ax + y = 8

bx + y = 5

Since a ≠ b, but a > b, the system has a solution

Answer:

g(2.5)= 2(2.5)+3

= 8

f(g(2.5))= f(8)=8^2+4*8

=16+ 32

= 48

What is an<br> equation of the line that passes through the points (-6,5) and (6, 7)?

NemiM [27]

Answer:

$y = \frac{1}{6} x + 6$

Step-by-step explanation:

The equation of a line can be written in the form of y=mx+c, where m is the gradient and c is the y-intercept. This form is known as the slope-intercept form.

Use the gradient formula below to find the value of m:

$gradient = \frac{y1 - y2}{x1 - x2}$

*(x₁, y₁) is the first coordinate and (x₂, y₂) is the second coordinate.

$m = \frac{7 - 5}{6 - ( - 6)} \\ m = \frac{2}{12} \\ m = \frac{1}{6}$

Substitute the value of m into the equation:

y= ⅙x +c

To find the value of c, substitute a pair of coordinates.

When x= 6, y= 7,

$7 = \frac{1}{6} (6) + c \\ 7 = 1 + c \\ c = 7 - 1 \\ c = 6$

Thus, the equation of the line is y= ⅙x +6.
