Answer:
<h3>ya-z/1+y</h3>
Step-by-step explanation:
Making x the subject of the formula;
y=x+z/a-x
Cross multiply
y(a-x) = x+z
ya - yx = x+z
Collect like terms
x+yx = ya - z
x(1+y) = ya - z
x = ya-z/1+y
Hence the value of x is ya-z/1+y
you could use the factor tree. If you don't know how to do this youtube it. its very easy.
Answer:
Screen shot the question and attach it and i will do it cus you making no sense
Step-by-step explanation:
Answer:
Step-by-step explanation:
9=-d+17
(add d to both sides because it is the opposite of subtracting)
9+d=17
(subtract 9 from both sides because it is the opposite of adding)
d=17-9=8
The graph at option 1 shows the given inequality y < x² + 1. The domain and range of the given inequality is {x: x ∈ (-∞, ∞)} and {y: y ∈ [1, ∞)}.
<h3>How to graph an inequality?</h3>
The steps to graph an inequality equation are:
- Solve for the variable y in the given equation
- Graph the boundary line for the inequality
- Shade the region that satisfies the inequality.
<h3>Calculation:</h3>
The given inequality is y < x² + 1
Finding points to graph the boundary line by taking y = x² + 1:
When x = -2,
y = (-2)² + 1 = 4 + 1 = 5
⇒ (-2, 5)
When x = -1,
y = (-1)² + 1 = 2
⇒ (-1, 2)
When x = 0,
y = (0)² + 1 = 1
⇒ (0, 1)
When x = 1,
y = (1)² + 1 = 2
⇒ (1, 2)
When x = 2,
y = (2)² + 1 = 5
⇒ (2, 5)
Plotting these points in the graph forms an upward-facing parabola.
So, all the points above the vertex of the parabola satisfy the given inequality. Thus, that part is shaded.
From this, the graph at option 1 is the required graph for the inequality y < x² + 1. The boundary line is dashed since the inequality symbol is " < ".
