Write in slope-intercept form an equation of the line that passes through the given points. (-16,8), (-4,5)

Answers

Answer:

y=-1/4x+4

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(5-8)/(-4-(-16))

m=-3/(-4+16)

m=-3/12

m=-1/4

y-y1=m(x-x1)

y-8=-1/4(x-(-16))

y-8=-1/4(x+16)

y-8=-1/4x-16/4

y-8=-1/4x-4

y=-1/4x-4+8

Step-by-step explanation:

From the above question, we know that:

Cross Multiply

$10 × x attendees = $14 × 5 attendees

x attendees = $14 × 5 attendees/$10

x attendees = 7 attendees

Therefore, if the budget for the cooperate team building is $14, the number of attendees is 7

The first three terms of a sequence are given. Round to the nearest thousandth (if necessary). 8,17,26 fine the 31 term

Answers

Answer:

278

Step-by-step explanation:

Given

[tex]Sequence:= 8, 17, 26[/tex]

Required

The 31st term

The given sequence is an arithmetic sequence because

[tex]d = 17 -8= 26 -17 =9[/tex]

The 31st term, is then calculated as:

[tex]T_n = a + (n - 1)d[/tex]

Where

[tex]a = 8[/tex] --- The first term

[tex]T_{31} = 8 + (31 - 1)*9[/tex]

[tex]T_{31} = 8 + 30*9[/tex]

[tex]T_{31} = 8 + 270[/tex]

[tex]T_{31} = 278[/tex]

"-3x" + 5 < "-10" Inequality 2: 7x + x - 4 > 28 Which of the following values makes BOTH inequalities TRUE? Select all that apply! 12 "-5" −152 "-8.25" 23 48 325

Answers

Answer:

12, 23, 48, 325

Step-by-step explanation:

So, when given two inequalities and asked to find the values that make both true, it is considered a system of equations. To solve a system of equation, you have to graph the inequalities and find where they intersect.

Inequality 1:

(-3x) + 5 < (-10)

Inequality 2:

7x + x - 4 > 28

simplifies to: 8x - 4 > 28

When graphed, the inequalities don't intersect, but rather have a similar shaded area overlapping from the point of 5 and greater.

Find the surface area of the prism. Enter your answer in the box. A rectangular prism with dimensions 6 meters by 3 meters by 12 meters.

Answers

Given:

Dimensions of a rectangular prism are 6 meters by 3 meters by 12 meters.

To find:

The surface area of the prism.

Solution:

The surface area of a rectangular prism is:

[tex]A=2(lb+bh+hl)[/tex]

Where, l is length, b is breadth and h is height.

Putting [tex]l=6,b=3,h=12[/tex], we get

[tex]A=2(6\times 3+3\times 12+12\times 6)[/tex]

[tex]A=2(18+36+72)[/tex]

[tex]A=2(126)[/tex]

[tex]A=252[/tex]

Therefore, the surface area of the prism is 252 square meters.
