A linear function is graphed below.

Evgen [1.6K]

Answer:

$-1\frac{1}{2}$

Step-by-step explanation:

We have two coordinate points and are asked to find a slope.

When finding slope, we can use the formula listed :

$\frac{y^2-y^1}{x^2-x^1}}$

To understand what the variables are, you can take this :

$(x^1,y^1)$

$(x^2,y^2)$

Substitute the points :

$(-1,4)$

$(5,-5)$

Now substitute it into the formula :

$\frac{-5-4}{5-(-1)}$

$\frac{-3}{2}$

$-1\frac{1}{2}$

There are 34 Pre-K children and 29 kinder garden children on the playground, some boys and some girls. The ratio of boys to girl

Natali [406]

There are 27 boys on the playground.

Step-by-step explanation:

No. of Pre-K children = 34

No. of kindergarten children = 29

Total no of children = 29+34 = 63

Ratio of boys to girls = 3:4

Total ratio = 3+4 = 7

Therefore,

boys proportion = $\frac{3}{7}$

Total number of boys = $\frac{3}{7}\ of\ total\ number\ of\ children$

$Total\ number\ of\ boys = \frac{3}{7} *63\\Total\ number\ of\ boys = \frac{189}{7} \\Total\ number\ of\ boys = 27$

There are 27 boys on the playground.

zhenek [66]

In order to overlook someone's faults, it takes love and an understanding that you are not perfect.
When you love someone, you tend not to see that person's flaws, or even if you do see them, you believe those flaws are negligible. Once you understand that you yourself are not perfect (as any other human being), it will be easier for you to overlook someone else's faults.
