D = (5-1)/(13-(-3)) = 0.25

f(13) = 13d + x = 13 * 0.25 + a = 3.25 + a = 5
a = 1.75

f(x) = 1.75 + 0.25x

SpyIntel [72]

Answer:

10 Girls

Step-by-step explanation:

Total number of girls in Alden Middle school= 25 girls

Percent of girls play for travel team= 40%

We have to find the numbers of girls who play for middle school team

Numbers of girls who play for middle school team= 25 × $\frac{40}{100}$

Numbers of girls who play for middle school team=25 × $\frac{40}{100}$

Numbers of girls who play for middle school team=10

Hence the number of girls play for travel team= 10 girls.

Hence, the correct answer is 10.

Y=6x+3/7 in standard form

Makovka662 [10]

bearing in mind that

standard form for a linear equation means

• all coefficients must be integers, no fractions

• only the constant on the right-hand-side

• all variables on the left-hand-side, sorted

• "x" must not have a negative coefficient

so, let's multiply both sides by the LCD of 7 to do away with the denominators

$\bf y=6x+\cfrac{3}{7}\implies \stackrel{\textit{multiplying both side by the }\stackrel{LCD}{7}}{7(y)=7\left( 6x+\cfrac{3}{7} \right)}\implies 7y=42x+3\\\\\\-42x+7y=3\implies 42x-7y=-3$
