rewrite this equation in the form y=ax+b

2y=4x-8

We have to make sure the denominators are equal.

10 goes into 5 evenly, so we only need to multiply one term to get a common denominator.

Multiply 2 by 2, and get 4, then we multiply 5 by 2 and get 10

Now the equation is 4/10 + 6/10

Since our denominators match, we can add the numerators.

4 + 6 = 10

That gives us the sum, which is 10/10 aka 1 whole

your welcome :) (btw can u please give brainly?)

Answer:

2/5 + 6/10 = 1

Step-by-step explanation:

first let’s change 2/5 so it has the same denominator as 6/10.

2/5 * 2/2 = 4/10

now add

4/10 + 6/10 = 1

Answer:

880

Step-by-step explanation: Every three days the balance increases by 120 so you would divide 120 by 3 to get 40. This would mean that the balance increases by 40 everyday so after seven days the balance would be 880

Answer:

2.75 hours

Step-by-step explanation:

Speed is 24km per hour ([tex]\frac{24km}{1hour}[/tex]), and the bus covered 66km.

We need to get a value of km with the rate (24/1) and distance (66) given.

We get:  [tex]\frac{1hour}{24km} *66km[/tex].  

The km cancel out, leaving us with 66/24 hours, or 2.75 hours.

Answer:

C, D, E

Step-by-step explanation:

Remote angles theorem; when one side of a triangle is extended, the angle formed must equal the sum of the two angles in the triangle, that it isn't adjacent to.

C. (m<4) > (m<1), this has to be true because of remote angles theorem.

(m<4) must be greater than (m<1) because it is equal to (m<1) + (m<2)

D. (m<4) > (m<2), apply the same logic here, as was applied to the first problem.

E. (m<1) + (m<2) = (m<4), this is essentially remote angles theorem.

143 / 165 = 86.666666666667%

Answer:

y - (1.01nd + 7)

Step-by-step explanation:

Quinton bought n number of shares for d dollars and paid a 1% commission. It means he bought [tex]\dfrac{1}{100}nd=0.01nd[/tex]

He sold the stock for y dollars and paid a flat fee of  $7. It means he sold y-7.

We need to find Quinton's net proceeds algebraically. It will be given as :

[tex]y-7-0.01nd\\\\=y-(0.01nd+7)[/tex]

Hence, the correct option is (d) i.e. y - (1.01nd + 7)

Answer:

The longest day of the year is day 172  

Step-by-step explanation:

Since the length of day is L(t)=727+22sin[2π(t−80.75)/365], the maximum length of day is obtained when sin[2π(t−80.75)/365] is at its maximum value which is 1. So. sin[2π(t−80.75)/365] = 1

We now solve this to find the day at which this maximum value occurs.

sin[2π(t−80.75)/365] = 1

[2π(t−80.75)/365] = sin⁻¹(1)

[2π(t−80.75)/365] = π/2

dividing both sides by 2π/365, we have

[2π(t−80.75)/365] ÷ 2π/365 = π/2 ÷ 2π/365

t−80.75 = 365/4

t−80.75 = 91.25

t = 91.25 + 80.75

t = 172

The longest day of the year is day 172

a) 31.4 cm b) 22.0 cm c) 9.4 mm d) 18.8 m e) 1.6 m f) 28.3 cm g) 78.5 cm h) 9.7 m

Step-by-step explanation:

All it really is multiply the diameter which is the straight line through the center of the circle

C = d × \pi

The circumference of the circles is A. 31.4 cm, B. 22cm approx,

C. 9.4 mm, D. 18.88 m, E. 1.6 m, F. 28.3 cm, G. 78.5 cm, H. 4.1 m.

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the center.

Given circles,

circumference  of circle is 2πr in form of diameter = πd

where d is diameter,

A. given d = 10 cm

circumference   = c = πd

c = 3.14 x 10

c = 31.4 cm

B. given, d = 7 cm

c= πd

c = 3.14 x 7

c = 21.98 cm = 22 cm approx

C.given, d= 3 mm

c = πd

c = 3.14 x 3

c = 9.4 mm

D. given d = 6 m

c = πd

c = 3.14 x 6

c = 18.8 m

E. given c = 0.5 m

c = πd

c = 3.14 x 0.5

c = 1.6 m

F. given d = 9 cm

c = πd

c = 3.14 x 9

c = 28.3 cm

G. given d = 25 cm

c = πd

c = 3.14 x 25

c = 78.5 cm

H. given d = 1.3 m

c = πd

c = 3.14 x 1.3

c = 4.1 m

Hence the circumference is as follows.

Answer:

The option D represents an interval with a positive average rate of change.

Step-by-step explanation:

Let [tex]f(x) = x^{2}+10[/tex], the average rate of change on the interval [tex][a,b][/tex] is represented by the definition of the secant line:

[tex]\bar f = \frac{f(b) -f(a)}{b-a}[/tex] (1)

Where:

[tex]a[/tex], [tex]b[/tex] - Lower and upper bounds, dimensionless.

[tex]f(a)[/tex], [tex]f(b)[/tex] - Function evaluated at lower and upper bounds, dimensionless.

Now we proceed to check each option:

A. [tex]a = -3[/tex], [tex]b = 3[/tex]

[tex]\bar f = \frac{19-19}{3-(-3)}[/tex]

[tex]\bar f = 0[/tex]

B. [tex]a = -4[/tex], [tex]b = -1[/tex]

[tex]\bar f = \frac{11-26}{(-1)-(-4)}[/tex]

[tex]\bar f = -5[/tex]

C. [tex]a = -3[/tex], [tex]b = 1[/tex]

[tex]\bar f = \frac{11-19}{1-(-3)}[/tex]

[tex]\bar f = -2[/tex]

D. [tex]a = -1[/tex]. [tex]b = 2[/tex]

[tex]\bar f = \frac{14-11}{2-(-1)}[/tex]

[tex]\bar f = 1[/tex]

Answer:

D, ininitely many

Step-by-step explanation:

A- incorrect since the lines intersect

B - incorrect since the lines intersect at more than one point

C - incorrect since the lines intersect at more than 2 points

D- correct since the lines intersect at infinitely many points (since they're the same line)

Answer:

D) infinitely many solutions

Step-by-step explanation:

we can see that the graphs shows two lines that are exactly one on top of the other. This means that every point on either line will also coincide with a point on the other line.

Because of this, every point on one line is also a solution on the other line, thus there are infinitely many solutions.

Step-by-step explanation:

Answer:

always true

Step-by-step explanation:

Distribute the left side

2(x + 3) = 2x + 6

Simplify the right side

5x + 6 - 3x ← collect like terms

= 2x + 6

Thus

left side = right side , so always true

Equation 2(x + 3) = 5x + 6 - 3x is an identity which is always true.

An identity is an equation which is always true, no matter what values are substituted.

Identities can be written with the sign ≡.

Given equation,

2(x + 3) = 5x + 6 - 3x

Simplifying

2x + 6 = 2x + 6

LHS = RHS

Answer:

The correct option is; A. [tex]y = \dfrac{7}{4} x + 7[/tex]

Step-by-step explanation:

The given equation is 4·y - 7·x = 8

The coordinates of the point the line passes = (-4, 0)

By dividing the given equation by 4, we have;

4·y/4 - 7/4·x = 8/4

Which gives;

y  - 7/4·x = 2

y   = 7/4·x + 2

Which is the equation of a straight line in slope and intercept form, y = m·x + c, with the slope, m = 7/4, and the y-intercept = 2

Given that the required line is parallel to the graph of the equation, 4·y - 7·x = 8, the slopes of both equations are equal we have;

Slope of required line = 7/4, point on the line = (-4, 0), which gives the following point and slope form equation of a straight line;

y - 0 = 7/4 × (x - (-4))

y = 7/4·x + 7/4 × 4 = 7/4·x + 7

The equation of the line is therefore;

y = 7/4·x + 7

C, x is greater than or equal to 2

Both equations have X equaling to 2
