What is the solution of the system when just looking at the equations? No Graph!

Mathematics

The slope-intercept form: y = mx + b

m - slope

b - y-intercept

y = 5x + 2 and y = 5x – 8

m = 5 m = 5

b = 2 b = -8

When comparing equations:

1. Put in slope-intercept form.

2. Compare the slopes and the y-intercepts!

This system has no solution.

Because we have the same slopes and different y-intercepts.

If the slopes are the same and the y-intercepts are the same, then that system has infinitely many solutions.

If the slopes are different, then that system has one solution.

H(1) = can someone help my brother ?

Fantom [35]

Answer:

h(1) = -2

Step-by-step explanation:

What h(1) is saying is the value of x = 1. We need to find the y-value.

We see from the graph that when x = 1, y = -2.

Jalil and Victoria are each asked to solve the equation ax – c = bx + d for x. Jalil says it is not possible to isolate x becaus

LUCKY_DIMON [66]

Answer:

Step-by-step explanation:

Give the expression ax – c = bx + d, we are isolate x i.e we are to make x the subject of the formula.

ax – c = bx + d

Step 1: subtract bx from both sides

ax – c = bx + d

ax-bx = d+c

Step 2: Factor out x in the left hand side of the resulting expression

x(a-b) = d+c

Step 3: Divide both sides by the coefficient of i.e (a-b)

$\frac{x(a-b)}{a-b} = \frac{d+c}{a-b}$

$x = \frac{d+c}{a-b}$

Hence Victoria can justify the step 3 of her work by dividing both sides of the expression in 2 by a-b

It is not B and D, because R is not in the right place.

It is also not C, since P is not in the upper right quadrant, but the lower left one. The correct grid is A
