What is the x intercept of y=4x-8

Answers

Answer 1

Answer:

the answer is 2

Step-by-step explanation:

0=4x-8

-4x=-8

x=2

Answer 2

Answer:

x=2

Step-by-step explanation:

the x intercept is where the graph intersects the x axis also called the root of the equation.

y=0 if the graph intersects the x-axis

0= 4x-8; add 8 to both sides

8 = 4x ; divide both sides by 4

2=x

Answers

Answer:

5(n+1)/((n+1)(n+3))

5/(n+3) is a answer

Step-by-step explanation:

(n+1)/(n+1)=1

The solution is, the simplified product of the expression 5/n+1*n+1/n+3 is 5/(n+3) .

here, we have,

given that,

the expression is 5/n+1*n+1/n+3

now, we have to find the simplified product.

as, * means the multiplication,

we get,

5/n+1*n+1/n+3

=5*(n+1)/((n+1)*(n+3))

now, we know that,

(n+1)/(n+1)=1

so, we get,

5*(n+1)/((n+1)*(n+3))

=5*1 /(n+3) *1

=5/(n+3) is a answer

Cynthia invests some money in a bank which pays
5% compound interest per year.
She wants it to be worth over £8000 at the end of 3 years
What is the smallest amount, to the nearest pound, she can invest?

Answers

Answer:

Intital investment= £6,911.57

Step-by-step explanation:

Giving the following information:

Future Value (FV)= £8,001

Number of periods (n)= 3 years

Interest rate (i)= 5% = 0.05 compounded annually

To calculate the initial investment (PV) needed to reach £8,001 (over £8,000) in 3 years, we need to use the following formula:

PV= FV / (1+i)^n

PV= 8,001 / (1.05^3)

PV= £6,911.57

An isosceles triangle has a perimeter of 28.12 centimeters. The length of the longest side is 13.08 centimeters. What could be the length of
one of the other sides of the triangle?
A. 3.92 centimeters
B. 7.52 centimeters
C. 11.26 centimeters
D. 15.04 centimeters

Answers

Answer:

7.52 cm

Step-by-step explanation:

If we subtract the longest side from the whole perimeter, we get 28.12 - 13.08 = 15.04.

So the other two sides must be equal, since the triangle is isosceles.

That means 15.04 must be divided evenly betweem two sides.

15.04/2 = 7.52

So the 3 sides are 13.08 cm, 7.52 cm, and 7.52 cm.

You check the answer by adding all 3 sides together and we do indeed get the perimeter, 28.12 cm.

a taco cost?
O a) $2.75
O b) $3.00
O c) $3.25
O d) $3.50
O e) $3.75

Answers

Answer:

D. 3.50

Step-by-step explanation:

3t+2d=$13.00

4t+d=$15.25

3t+2d=$13.00

8t+2d=$30.50

E2-E1

5t=$30.50-$13.00

t=3.5

The taco cost is option D. 3.50

Given that,

If three tacos and two drinks cost $13.00, and four tacos and one drink costs $15.25.

Based on the above information, the calculation is as follows:

3t+2d=$13.00 ......(1)

4t+d=$15.25 .......(2)

Here we have to multiply by 2 in equation 2

So,

3t+2d=$13.00

8t+2d=$30.50

So,

5t=$30.50-$13.00

t=3.5

Find the length of the missing side of the right triangle,13 ydSydA. 194 ydB 13.93 ydC. 144 yaD. 12 yd Read the passage from Sugar Changed the World.With their victory, the people of Saint Domingue announced that the conflict between freedom and property was over: "All men are equal" meant that no men are property. This idea terrified the Englishand not merely because their sugar island of Jamaica was just over a hundred miles across the water from Saint Domingue. Indeed, slaves in Jamaica were beginning to sing a new song while they worked:One, two, tree,All de same;Black, white, brown,All de same;All de same.One, two, tree,All de same!That chant did more than threaten a slave revoltit was a challenge to all ranking hierarchies. Jamaica had already seen many slave revolts, and the reverend John Lindsay was certain that the talk of freedom and liberty in North America had inspired the slaves: "At our tables (where . . . every Person has his own waiting man behind him) we have I am afraid been too careless of Expressions, especially when the topic of American rebellion has been . . . brandished with strains of Virtuous Heroism. But the slaves did not need to overhear their masters to learn about the ideas of equality. Black sailors working ships running all through the islands were carrying the word. And if this spirit of liberty got out of hand, that could be really dangerous. After all, in England itself only 3 percent of the population had the right to vote. If this expanded idea of freedom spread, how safe were the kings and dukes, earls and knights, of England? Starting in fall 1793, British troops began arriving in Saint Domingue to reenslave people and return them to their sugar plantations. As Henry Dundas, the British secretary of war, put it, their goal was to "prevent a circulation in the British Colonies of the wild and pernicious Doctrines of Liberty and Equality.How do the authors use historical evidence to support their claim?
