Answer:
5.5
Step-by-step explanation:
y = 0.5x + 5
Use the slope-intercept form to find the slope and y-intercept.
<em>Slope: 0.5
</em>
<em>y-intercept: 5
</em>
Any line can be graphed using two points. Select two <em>x</em> values, and plug them into the equation to find the corresponding values.
To find the y intercept using the equation of the line, plug in 0 for the <em>x</em> variable and solve for y.
<em>y = 0.5(0) + 5
</em>
<em>y = 5</em>
To graph the y intercept using the equation of the line, plug in 1 for the x variable and solve for y.
<em>y = 0.5(1) + 5
</em>
<em>y = 5.5
</em>
Which means when x is 0, y intercept at 5 and when x is 1 y intercept at 5.5. Graph the line using the slope and the y-intercept, or the points.
This tells us, in practical terms, that, for every one unit that the x-variable increases (that is, moves over to the right), the y-variable increases (that is, goes up) by 50% of a unit.
Answer:
In a parallelogram, consecutive angles are supplementary. Thus,
B + C = 180^{\circ}
(2x+15)+x=180
3x+15=180
3x=165
x=55

Answer:
Step-by-step explanation:
<h3>to understand this</h3><h3>you need to know about:</h3>
<h3>tips and formulas:</h3>
- the parabola crosses f(x) at (4,0)
- the vertex of the parabola (2,6)
- vertex:(h,k)
- h=-b/2a
- k=f(x)
- vertex form:f(x)=a(x-h)²+k
- standard form:ax²+bx+c
<h3>let's solve:</h3>
the vertex form of the equation is
let's figure out a
since the parabola crosses f(x) at (0,4)
therefore
let's figure out b,c
- we have to substitute the value of a into the vertex form and then simply it to get b and c
therefore
- [tex] \sf \: c = 4[/tex
