Answer:

We need to find Factors of 14 that will also add and equal to 5

Step-by-step explanation:

Trinomial factorising

Answer:

see explanation

Step-by-step explanation:

p² - 5p - 14

We need to find the factors of the constant term (- 14) that will also add to give the coefficient of the p- term (- 5)

the factors are - 7 and + 2 , since

- 7 × + 2 = - 14 and - 7 + 2 = - 5

then

p² - 5p - 14 = (p - 7)(p + 2) ← in factored form

Answer:

S₁₁ = 88573

Step-by-step explanation:

the sum to n terms of a geometric sequence is

[tex]S_{n}[/tex] = [tex]\frac{a_{1}(r^{n}-1) }{r-1}[/tex]

where a₁ is the first term and r the common ratio

here a₁ = 1 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{3}{1}[/tex] = 3 , then

S₁₁ = [tex]\frac{1(3^{11}-1) }{3-1}[/tex] = [tex]\frac{1}{2}[/tex] (177147 - 1) = [tex]\frac{1}{2}[/tex] × 177146 = 88573

Answer:

42 minutes

Step-by-step explanation:

there are 60 minutes in one hour.

from 12 pm, 1 hour and 35 minutes have passed to get to 1:35 pm

from 12 pm, 2 hours and 17 minutes have passed to get to 2:17 pm

we are trying to figure out the start to end time, or the difference between the times

2 hours and 17 minutes - 1 hour and 35 minutes

1 hour = 60 minutes

if we convert everything to minutes we can get a definitive time in one single unit

2 hours = 1 hour * 2 = 60 minutes * 2 = 120 minutes

1 hour = 60 minutes

plug these in

(120 + 17) minutes - (60 + 35) minutes

= 137 minutes - 95 minutes

= 42 minutes as our answer

Answer:

1 hotdog is $3.5.

1 drink is $2.

Step-by-step explanation:

18.50= 3x+4y(times 5)

25.50=5x+4y(times -3)

92.5=15x+20x

-76.5=-15x+-12y

16=-8y

2=y

18.50=3x+4(2)

10.50=3x+8

10.50=3x

3.5=x

Answer:

B

Step-by-step explanation:

if you divide the 2/88 you should get a price of 44. So Mechanic B charges $44 while Mechanic A charges $36. Subtract 44-36 and get 8. Since Mechanic B charges more, it would give you the answer listed in B.

The equation satisfies option B, Mechanic B charges $8 more per hour then mechanic A.

a collection of all points whose coordinates satisfy a given relation (such as a function) a diagram that represents the variation of a variable in comparison to that of one or more other variables, such as a series of one or more points, lines, line segments, curves, or areas

The fundamental subject of graph theory is graphs.

Given the Equation for cost charged by Mechanic A

y = 36x

where y = total cost and x = hours worked

graph shows the  total cost charged by Mechanic B

from graph we the coordinates (0, 0) and (2, 88)

when x = 0, y = 0 and when x = 2,  y  =  88

the equation satisfy the condition is

y = 44x

cost for one hour for Mechanic A

y = 36x (x = 1)

y = $36

cost for one hour for Mechanic B

y = 44x (x = 1)

y = $44

Mechanic B is $8 more than Mechanic A

Hence Mechanic B charges $8 more per hour then mechanic A.

Answer:

m∠Z=146

m∠X=34

Step-by-step explanation:

Since this is an Isosceles Trapezoid, we can assume that m∠Z=m∠Y, because an isosceles trapezoid has two pairs of congruent angles, therefore m∠Z=146.

Since angle Y and Angle X are same side interior and line ZY║WX, we can assume that m∠X+m∠Y=180. Substitute values:

[tex]146+X=180\\Y=34[/tex]

Answer: 50, 208 mm²

Step-by-step explanation:

    The lateral area is the surface area excluding the bottom, also known as the base. This means we will be solving for two rectangles and two triangles.

[The Rectangles]

    They are both congruent, so I will do the following;

A = 2(L * W)

A = 2(7 mm * 24 mm)

A = 2(168 mm)

A = 336 mm²

[The Triangles]

    The area of a triangle is [tex]\frac{B * H}{2}[/tex] However, they are both congruent. I will do the following;

A = B * H

A = 24 mm * 2,078 mm

A = 49,872 mm²

[The Total]

     Lastly, I will add them together.

336 mm² + 49,872 mm² = 50, 208 mm²

Answer:

60°

Step-by-step explanation:

the triangle need to have 180°. The up right corner is 60 because 120 + 60 = 180. Then I extended to rhombus where you have two sets of same angles. 125 + 55 = 180. 125 + 125 = 250. 360 - 250 = 110. 110 ÷ 2 = 60

Answer:

The X-coordinates will decrease by 6 units because, anytime you move something to the left on a coordinate plane you are decreasing the x value

Answer:

The x-coordinates will decrease by 6.

Step-by-step explanation:

So when you look at a graph, the left side has smaller numbers than the right side because as you go down it becomes negative and the right means it is going positive. So if you are moving to the left you are getting smaller so you are decreasing. The other options with y-axis is not true because the y-axis is vertical.
