How do you graph y=3x+4

1 answer:

7 0

3x is the slope and 4 is the y intercept

You would start at the origin (0,0)

Go up 4 and make a point

Then from that point go up 3 over 1 and make another point

Pepsi [2]

Andrew has saved 36 number of R5 coins, 90 number of R2 coins and 126 number of R1 coins.

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

The coins are in the ratio 2:5:7 respectively. If he has a R90 in R2 coins. If x represent the total coins, hence:

(5/14) * x = 90

x = 252

Number of R5 coins = (2/14) * 252 = 36

Number of R1 coins = (7/14) * 252 = 126

Andrew has saved 36 number of R5 coins, 90 number of R2 coins and 126 number of R1 coins,

There were 80 boys and 95 girls on the middle school track team last year this year the number of boys increased by 15% well the

shutvik [7]

Answer:

E. 4% decrease

Step-by-step explanation:

To find out if we had an increase or a decrease, we will first need to set out variables.

80 boys

95 girls

So last year we had a total of:

80 + 95 = 175 Track team members

This year we had an increase in the number of boys.

15% boys or 0.15

Now since it's an increase, we add 1 to 0.15.

Total number of boys = 80 x (1.15)

Total number of boys = 92

Then we had a decrease in the number of girls.

20% girls or 0.20

Now we take the number of girls and multiply them by 0.20 and subtract the amount we get to the number of girls initially.

Total number of girls = 95 - (95 x 0.20)

Total number of girls = 95 - 19

Total number of girls = 76

So all together we have:

92 boys + 76 girls = 168

Now let's get the difference of the number of members last year and this year.

175 - 168 = 7

So we have 7 less members from last year.

Now we find how many percent 7 members is of 175 members.

Now we divide 7 by 175.

7 / 175 = 0.04

Then we multiply 0.04 by 100 to get the percentage value.

0.04 x 100 = 4%

So since we know that we have less than the initial number of members, then it means that it is a decrease.

So we had a 4% decrease in the number of members.

Question 5 (1 point)

bearhunter [10]

Answer:

$T(x)=84-2x$

Step-by-step explanation:

Linear Modeling

The initial temperature outside is 84 degrees.

We are told the temperature drops 2 degrees every hour.

Let's call x to the number of hours elapsed. After x hours, the temperature would have dropped by 2x degrees, since it's a rate of 2 degrees per hour.

That drop is subtracted from the initial temperature to produce the linear model as follows:

$\mathbf{T(x)=84-2x}$

This is the linear equation that represents the described situation.
