Answer:

when adding fractions make sure the bottom number is the same

so for number 2 make sure both are 4 on the bottom of the fraction by multiplying by 2 maybe 1/4+2/4 that would equal 3/4 not 1

Answer:

Step-by-step explanation:

1/2+1/4=0.75 less than 1

3/6+2/3=1.17 greater than 1

need help with this Drag the points to create graphs of linear relationships that have different y-intercepts and slopes of 1/5,

ludmilkaskok [199]

Linear relationships that have different y-intercept and slope of 1/5 is y=1/5 x+25/6.

Given that, the slopes are 1/5, 3/5 and 6/5.

<h3>What is slope of a line?</h3>

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The coordinate points from the given figure are (6, 5), (5, 1) and (4, 3).

Substitute m=1/5 and (x, y)=(6, 5) in y=mx+c, we get

5=1/5 ×6+c

⇒ c=5- 5/6

⇒ c=25/6

Put m=1/5 and c=25/6 in y=mx+c, we get

y=1/5 x+25/6

Substitute m=3/5 and (x, y)=(5, 1) in y=mx+c, we get

1=3/5 ×5+c

⇒ c=-2

Put m=3/5 and c=-2 in y=mx+c, we get

y=3/5 x-2

Substitute m=6/5 and (x, y)=(4, 3) in y=mx+c, we get

3=6/5 ×4+c

⇒ c=3-24/5

⇒ c= -9/5

Put m=6/5 and c= -9/5 in y=mx+c, we get

y=6/5 x-9/5

Therefore, linear relationships that have different y-intercept and slope of 1/5 is y=1/5 x+25/6.

Pls help asap, I put attachments down below, I will also give brainliest

Answer:

Question 1;

∴ The y values are 1.49 , 2.98 , 4.47 and 5.96

Question 2;

∴ The y values are 2.00 , 2.8 , 3.6 and 4.4

Question 3;

∴ The y values are -9 , -3 , 3 and 9

Question 4;

∴ y values are $\frac{1}{2}$ , $\frac{3}{4}$ , 1 and $\frac{5}{4}$

Step-by-step explanation:

Question 1;

Given data,

Apples cost $\$1.49$ per pound.

$x$ = weight in pound

$y$ = Cost in $\$$

Here the relation between $x$ and $y$ comes;

$y=x\times 1.49$ (equation 1)

Let, Plug all x value in equation 1;

when $x=1$ then $y=1\times 1.49=1.49$ ,

when $x=2$ then $y=2\times 1.49=2.98$ ,

when $x=3$ then $y=3\times 1.49=4.47$ ,

when $x=4$ then $y=4\times 1.49=5.96$ ,

∴ The y values are 1.49 , 2.98 , 4.47 and 5.96

Question 2;

From question,

Initial fees of cab is $\$$ 2.00 and Passengers are charged $\$$ 0.80 for every minute.

Let,

$x$ = Time in minutes

$y$ = Amount in $\$$

Here the relation between x and y comes;

$y=x\times 0.80 +2.00$ (equation 2)

Let,By plug all x value in equation 2;

When $x=0$ then $y=0\times 0.80+2.00=2.00$ ,

When $x=1$ then $y=1\times 0.80+2.00=2.8$ ,

When $x=2$ then $y=2\times 0.80+2.00=3.6$ ,

When $x=3$ then $y=3\times 0.80+2.00=4.4$ ,

∴ The y values are 2.00 , 2.8 , 3.6 and 4.4

Question 3;

Given relation between $x$ and $y$ ;

$y=6\times x +3$

Plug all the values of x in above equation,

When $x=-2$ then $y=(6\times -2) +3=-9$ ,

When $x=-1$ then $y=(6\times --1) +3=-3$ ,

When $x=0$ then $y=(6\times 0) +3=3$ ,

When $x=1$ then $y=(6\times 1) +3=9$ ,

∴ The y values are -9 , -3 , 3 and 9

Question 4;

Given relation between $x$ and $y$ ;

$y=(\frac{1}{4} \times x)+1$

Plug all the values of x in above equation,

When $x=-2$ then $y=(\frac{1}{4} \times -2)+1=\frac{1}{2}$ ,

When $x=-1$ then $y=(\frac{1}{4} \times -1)+1=\frac{3}{4}$ ,

When $x=0$ then $y=(\frac{1}{4} \times 0)+1=1$ ,

When $x=1$ then $y=(\frac{1}{4} \times 1)+1=\frac{5}{4}$ ,

∴ y values are $\frac{1}{2}$ , $\frac{3}{4}$ , 1 and $\frac{5}{4}$

Veronica gave 20% of her money to Bill. She used 50% of the remaining money to buy books. If Veronica gave $35 to Bill, she spen

Verdich [7]

The first step to solve this problem is to compute for the total money of Veronica. You can do this by:

$35 (given to bill) / 20% (percentage of her money given to Bill) = $175

Since you already know the total money of Veronica, you can now compute how much she spent to buy books which are 50% of her remaining money after giving Bill $35.

($175 - $35) x 50% = $70

Therefore, she spent $70 for her books.

$175 – $35 – $70 = $70

Therefore, she has $70 left.

Which expression uses the greatest common factor and the distributive property to rewrite the sum 75 + 45?

Vedmedyk [2.9K]

<span>75 + 45

First let's find the greatest common factor.
75: 1, 3, 5, 15, 25, 75
45: 1, 3, 5, 9, 15, 45
Their GCF is 15.

To get 75, you multiply 15 by 5.
To get 45, you multiply 15 by 3.

Therefore, 15(5 + 3) = 75 + 45.
