help me please, it’s urgent. i know how to solve this but how does the equation go?

Answer:

False

Step-by-step explanation:

Multiplying the numerator and the denominator by a number is basically multiplying the equation by 1, meaning that it won't change the value.

Keeping that in mind, 6/8 can be reduced to 3/4 by multiplying the top and bottom by 1/2, meaning they are equal.

To actually multiply a fraction to make it 2 times itself, you only multiply the numerator(top), not the denominator(bottom).

False

Answer:

Step-by-step explanation:

The equation y = -3x + 5 represents a linear function. The -3 represents the slope of the line. This means that the slope is -3 . The 5 in the equation represents the y-intercept of the line. This is where the graph crosses the y-axis.

Compare the original equation with the standard form to get all the values.

[tex]y=-3x+5\\y=mx+c[/tex]

If we compare m= -3 and c=+5 where m is the slope/gradient and c is the y-intercept.

The equation y = -3x + 5 represents a Linear function. The -3 represents the slope of the line. This means that the slope is -3. The 5 in the equation represents the y-intercept of the line. This is where the graph crosses the y axis.

Therefore,

Compare the original equation with the standard form to get all the values.

y = -3x + 5

y = mx +c

If we compare m = -3 and c = 5 where m is the slope/gradient and c is the y-intercept.

Answer:

I got C) 1 and 1/4

Step-by-step explanation:

-0.5 + 0.75 = 0.25

1/5 = 0.20

0.25 divided by 0.20 would be over 1 because a fraction divided by another fraction brings the number while a whole number divided by a fraction would bring the number down.

0.25 divided by 0.20 = 1.25

Answer: 6.1e-17

Step-by-step explanation:

the evaluated expression in scientific notation is 6.1 × 10⁻⁵.

To evaluate and express the answer in scientific notation, we can simplify the expression and adjust the decimal point and exponent accordingly.

2.44 × 10⁻¹⁰ ÷ 4 × 10⁻⁶

First, divide 2.44 by 4, which gives us 0.61.

Next, subtract the exponents by applying the division rule for exponents:

10⁻¹⁰ ÷ 10⁻⁶ = 10⁽⁻¹⁰⁻⁽⁻⁶⁾⁾ = 10⁽⁻¹⁰⁺⁶⁾ = 10⁻⁴

Therefore, the simplified expression is 0.61 × 10⁻⁴.

To express the answer in scientific notation, we can move the decimal point one place to the right, resulting in 6.1 × 10⁻⁵.

Hence, the evaluated expression in scientific notation is 6.1 × 10⁻⁵.

x = -75

Answer:

y=3x

Step-by-step explanation:

Equation is y=mx+b

Slope is 3/1 or 3x.

Y-intercept is at the origin or (0,0), so you take the y-coordinate.

Plug them into the equation.

Answer:

3/8

Step-by-step explanation:

An estate has to be divided among the 5 persons.

Given that the 1st person received 1/8 of the estate,

the 2nd person received 1/5 of the estate,

the 3rd person received 1/5 of the estate,

and the 4th person received 1/10 of the estate.

Let the 5th person received the x part of the estate.

The sum of all the fractional parts of one estate equals to 1, so

[tex]\frac 1 8+\frac 1 5+\frac 1 5+\frac 1 {10}+x=1[/tex]

[tex]\Rightarrow \frac 5 8 +x =1[/tex]

[tex]\Rightarrow x =1-\frac 5 8 =\frac 3 8.[/tex]

Hence, the last person received 3/8  of the estate.

Step-by-step explanation:

Answer:

a. A continuous graph

b. a straight line graph with a gentle positive slope

c. The graph consists of three straight lines attached end to end, with the first segment being an inclined positively sloped graph, the second segment is an horizontal line while the third segment is a gentle positively sloped straight line

Step-by-step explanation:

a. A continuous graph

Given that the rain gauge is a digital rain gauge, the values transmitted to the indoor display are those collected by the outdoor sensor, we have that the output to the transmitter can be any value within a possible and finite range of values, therefore the graph is continuous

b. Whereby it rained at a constant rate of 0.1 inch per hour over 24-hour period, we have;

i) Whereby the graph is the level of water in the rain gauge over a given period of time, the shape of the graph will be a straight line graph with a gentle positive slope of 0.1 the domain will be from 0 to 24 hours, while the range will be from 0 to 2.4 inches

c) i) Given that i) the rain falls at a constant rate of 0.1 inch per hour for 6 hours, and ii) over the next 6 hours it stops raining, after which iii) it rained 0.2 inch for the next 12 hours, we have;

i) In the first part The graph will be a straight line graph with a gentle positive slope of 0.1, up to the point (6, 0.6)

ii) When the rain stops for 6 hours, from the point (6, 0.6) to the point (12, 0.12) the graph will be an horizontal line

iii) From the point (12, 0.12) to the point (24, 0.24), is represented on the graph by a straight  line with a gentle positive slope of 0.2.

Answer:

10.75

Step-by-step explanation:

The cost of an adult ticket is £6 more than that of a child ticket, so will be shown by c+6.

Now, we are told that the cost of four child tickets and two adult tickets is £40.50, so we can put this in an equation and solve for c:

(c+6)+(c+6)+c+c+c+c=40.50

6c+12=40.50

6c=28.50

c=4.75

so, a childs ticket is 4.75

now to find the cost of an adult ticket you add 6,

4.75 + 6

= 10.75
