$a = 28.$

Step-by-step explanation:

${a}n = a + (n - 1)d$

$4 = a + (7 - 1)( - 4)$

$4 = a + 6( - 4)$

$4 = a + ( - 24)$

$4 = a - 24$

$4 + 24 = a$

$28 = a$

(OR)

$a = 28.$

triumphant college is planning to increase the registration fee by 11.5%.if the registration fee is currently N$ 1000, how much

frozen [14]

Current registration fee at triumphant college = N$ 1000

Percentage by which the registration fee will be increased next year = 11.5%

Registration fee at triumphant college next year :

= Current registration fee + 11.5% of current registration fee

$=\tt1000 + \frac{115}{10 \times 100} \: \: of \: \: 1000$

$= \tt1000 + \frac{115}{1000} \times 1000$

$=\tt 1000 + \frac{115000}{1000}$

$=\tt 1000 + 115$

$\color{plum} = \tt \:\bold{ N\$ \: 1115}$

Therefore, the registration fee at triumphant college next year = <u>N$ 1115</u>

Graph a line with a slope of 1/4 that contains the point (6, 3).

Semenov [28]

Answer:

The graph in the attached figure

Step-by-step explanation:

we know that

The equation of a line in point slope form is

$y-y1=m(x-x1)$

we have

$(x_1,y_1)=(6,3)$

$m=\frac{1}{4}$

substitute

$y-3=\frac{1}{4}(x-6)$

The easiest way to graph a line is to calculate the intercepts

The<u><em> x-intercept </em></u>is the value of x when the value of y is equal to zero

For y=0

$0-3=\frac{1}{4}(x-6)$

$-12=(x-6)$

$x=-12+6=-6$

The x-intercept is the point (-6,0)

The <u><em>y-intercept</em></u> is the value of y when the value of x is equal to zero

For x=0

$y-3=\frac{1}{4}(0-6)$

$y-3=-\frac{3}{2}$

$y=-\frac{3}{2}+3$

$y=1.5$

The y-intercept is the point (0,1.5)

Plot the intercepts and join the points to graph the line

(-6,0) and (0,1.5)

The graph in the attached figure
