Answer:

The answer is below

Step-by-step explanation:

a) g(10) = -3(10) + 1 = -30 + 1 = -29

b) f(3) = (3)² + 7 = 16

c) h(-2) = 12 / (-2) = -6

d) j(7) = 2(7) + 9 = 14 + 9 = 23

e) h(a) = 12 / (a) = 12 / a

f) g(b + c) = -3(b + c) + 1 = 1 - 3b - 3c

h) g(x) =  16

-3x + 1 = 16

3x = 1 - 16

3x = -15

x = -5

i) h(x) = -2

12 / x = -2

x = 12 / -2 = -6

j) f(x) = 23

23 = x² + 7

x² = 16

x = √16

x = 4

Answer:

The equation is;

y = -2x - 3

Step-by-step explanation:

If two lines are parallel, then they have an equal value of slope

Mathematically we can generally have the equation of a line written as;

y = mx + c

where m

is slope and c is the y-intercept

In the case of the equation given, the slope of the line is -2

So technically, we want to get the equation of a line that has a slope of -2 and it passes through (2,-7)

The point-slope form can be written as;

y-y1 = m(x-x1)

So the equation we want to get is;

y-(-7) = -2(x-2)

y + 7 = -2x + 4

y = -2x + 4 - 7

y = -2x - 3

Answer:

The length of each side is 4 m

Step-by-step explanation:

The volume of a cube is given by

V = s^3 where s is the side length

64 = s^3

Take the cube root of each side

64 ^ (1/3) = s^3 ^ (1/3)

4 = s

The length of each side is 4 m

Answer: 4 cubic meters

Step-by-step explanation:

The volume of a cube = a³

4³ = 64

So the length of each length has to be 4 cubic meters.

Answer:

m<A is 60 degrees

m<B is 30 degrees

Step-by-step explanation:

As the problem says, the sum of m<A and m<B=90 degrees (m<A+m<B=90). The given measures are (5x+10) for <A and 3x for <B

we can substitute (5x+10) and 3x as <A and <B into the equation

so:

5x+10+3x=90

Combine like terms

8x+10=90

subtract 10 from both sides

8x=80

divide by 8

x=10

Now substitute as x

m<A: (5*10+10)=50+10=60 degrees

m<B: (3*10)=30 degrees

Answer: [tex]9\ cm\equiv 5\ m[/tex]

Step-by-step explanation:

Given

The actual length of the parking lot is 75 m

length in the drawing is 135 cm

Here, 75 m is equivalent to 135 cm

Using unitary method

[tex]75\ m\equiv 135\ cm[/tex]

[tex]15\ m\equiv 27\ cm[/tex]

[tex]9\ cm\equiv \frac{15}{3}=5\ \text{m}[/tex]

Answer:

Step-by-step explanation:

As x is bigger than the number the 3.

x > 3 (The answer) ✔️

This symbol ‘>’ means ‘greater than’

So x is greater than 3

Answer: y=3x-8, y=5x-8, and y=2x-8

Step-by-step explanation:

These equations are all lines in slope-intercept form (y=mx+b where b is the y-intercept). y=3x-8, y=5x-8, and y=2x-8 all have -8 as the b value. Therefore, these equations have the same y-intercept.

Answer:

60

Step-by-step explanation:

There were 160 votes in total, and we need to figure out how much is 3/8 of it. Therefore, we need to find (3/8)*(160) (of is another word for multiply). The easiest method is to find 1/8 of 160 which is 20, and then multiply it by three to get 60, which is your answer!

Given:

Circle K has its center at (0,0) and a radius of 4.

Point N is at [tex](3,\sqrt{7})[/tex].

To find:

To check whether the point N lies on the circle or not. Then find the other point using symmetry.

Solution:

The standard form of a circle is

[tex](x-h)^2+(y-k)^2=r^2[/tex]       ...(i)

where, (h,k) is center and r is radius.

Circle K has its center at (0,0) and a radius of 4.  Putting h=0, k=0 and r= 4 in (i), to get the equation of circle K.

[tex](x-0)^2+(y-0)^2=4^2[/tex]

[tex]x^2+y^2=16[/tex]       ...(ii)

To check the point [tex]N(3,\sqrt{7})[/tex], put x=3 and [tex]y=\sqrt{7}[/tex] in (ii).

[tex](3)^2+(\sqrt{7})^2=16[/tex]

[tex]9+7=16[/tex]  

[tex]16=16[/tex]  

This statement is true. So. option [tex]N(3,\sqrt{7})[/tex] lies on the circle K.

According to the symmetry about the origin, if (x,y) lies on the graph then (-x,-y) also lies on that graph.

Since the center of the circle is origin, therefore, it is symmetrical about the origin.

Thus, point [tex]P(-3,-\sqrt{7})[/tex] must be on the circle K.

Therefore, the another point on the circle K is [tex]P(-3,-\sqrt{7})[/tex].

Answer:

560 votes

Step-by-step explanation:

Given that :

Sample votes :

Karim 28 votes ;Marisol 41 ; and Richard 11

Total sample votes = 28 + 41 + 11 = 80

Percentage vote obtained by Karim :

(28 / 80) * 100%

0.35 * 100%

35% of sample votes

Prediction if votes were 1600;

35% of 1600

0.35 * 1600

= 560 votes

Step-by-step explanation:

Answer:

$4.85

Step-by-step explanation:

Amount John has = $8.50 (Given)

Find amount left after spending on sweet

Sweet = $1.25

Amount left = $8.50 - $1.25 = $7.25

Find amount left after giving to 2 friends:

First friend = $1.20

Second friends = $1.20 x 2 = $2.40

$7.25 - $2.40 = $4.85

Answer: $4.85
