Evaluate the expression when y=8 and x=7 .

9y+x

Answer:

15 degrees

Step-by-step explanation:

3x+3x+90=180 (all angles in a triangle add to 180 degrees)

3x+3x=6x so 6x+90=180 degrees

To isolate 6x we -90 from 180 therefore 6x=90 degrees

To get x on its own, we then must divide 90 by 6 which is 15 hence why...

x=15 degrees

Answer:

The coordinates of a point are a pair of numbers that define its exact location on a two-dimensional plane. Recall that the coordinate plane has two axes at right angles to each other, called the x and y axis.

Answer:

D

Step-by-step explanation:

Find three points that are on the line solve as if the equation was y = -x - 3

x       0        5      -3

y       -3       -8      0

Plot these points (0, -3), (5, -8), (-3, 0)  on the graph, the graph will be a solid line because of the ≥  , and the graph will be shaded above the line

Answer:

Step-by-step explanation:

x=45

5(y-10)

Angles facing each other symmetrically are equal. so 4x-40 is equal to 3x+5. so x is 45 degrees.

Answer:

x = 85

Step-by-step explanation:

To solve, first find the angle of the other missing angle in the left by subtracting the outside angle from 180:

180 - 155 = 35

Then add this and the known angle:

35 + 60 = 95

Then subtract this from 180 to get the missing angle for x:

180 - 95 = 85

Step-by-step explanation:

the required number is 64 .

Step-by-step explanation:

6b^2-6b=3b^2

6b^2-3b^2-6b=0

3b^2-6b=0

3b(b-2)=0

3b=0 or b-2=0

So, b=0 or b=2

The breakeven point is when 23 skateboards are produced by the company.

Breakeven point is the point at which the revenue is equal to the cost. Hence the profit is 0.

Let us assume that the company makes x skateboards.

The cost = 45x + 2875

Revenue = 170x

At breakeven:

Revenue = cost

170x = 45x + 2875

125x = 2875

x = 23

Hence the breakeven point is when 23 skateboards are produced by the company.

C.(-31)

Step-by-step explanation:

= 5 - 4(1 + 2^3)

= 5 - 4(1 + (2 . 2 . 2))

= 5 - 4(1 + (4 . 2))

= 5 - 4(1 + 8)

= 5 - 4(9)

Answer:

Y=mx+b

Step-by-step explanation:

All your doing if finding were the point starts which would be 1 and the slope of the graph which is 0.5 so your answer would be y=0.5x+1 but in the way they want you to write it in it would be 1+0.5x=Y.

Answer:

y = 9/4x, 15_3/4

Step-by-step explanation:

Convert 6_3/4 to 27/4

3 costumes need 27/4 yards

1 costume needs 9/4 yards

y = 9/4x

x is 7. amount needed: y = 9/4(7) --> y = 63/4 = 15_3/4

Answer: 13 miles per hour

Step-by-step explanation: 52 divided by 4 to find unit rate

The speed of bike which covers 52 miles in 4 hours is 13 miles per hour.

In unit time the distance covered by any object is called speed.

In mathematical term, Speed is express as S=D/T,

where S=speed, D=distance, T= time.

Given that,

The distance covered by bike in 4 hours = 52 miles.

To find the speed of the bike,

Use formula

Speed = distance / time

Since, distance is 52 miles and time is 4 hours,

Therefore, speed = 52 / 4 = 13 miles per hour

The required speed of bike is 13 miles per hour.

Step-by-step explanation:

It's given that HIJK is a parallelogram. In a parallelogram, the adjacent angles sum up to 180°. Here, z & z + 68° together make 180° because they are adjacent angles.

z + z + 68 = 180

2z = 180 - 68

2z = 112

z = 112/2

z = 56°.

Answer:

  D. 43 degrees

Step-by-step explanation:

The sum of angles in a triangle is 180°. If x represents the measure of the third angle, then ...

  75° +62° +x = 180°

  137° +x = 180° . . . . . . . . . collect terms

  x = 180° -137° = 43° . . . . subtract 137° from both sides of the equation

The third angle measures 43°.

The expressions [tex]1.8^2 + 3 $ and $ 7 - 2 \times 0.43[/tex] ​ should be joined by not equals sign to form an inequality.

Given the expressions, 1.8² + 3 and 7 − 2⋅0.43,

Evaluate each of the expressions to find out if they are equal or not.

Thus:

1.8² + 3 = 3.24 + 3

1.8² + 3 = 6.24

7 − 2⋅0.43 = 7 - 0.86

7 − 2⋅0.43 = 6.14
