1.) If x varies directly as y and x = 35 when y = 7. What is the value of y when x = 25?

Fiesta28 [93]

Answer:

y = 5

Step-by-step explanation:

$x \ \alpha \ y$

$=> x = k \times y\\=> 35 = k \times 7\\=> k = 5$

$x = k \times y$

$=>25 = 5 \times y\\ =>5 = y$

Answer:

$f=\frac{9c}{5}+32$

Step-by-step explanation:

$c=\frac{5\left(f-32\right)}{9}$

Switch sides:

$\frac{5\left(f-32\right)}{9}=c$

Multiply both sides by 9:

$\frac{9\times5\left(f-32\right)}{9}=9c$

$5\left(f-32\right)=9c$

Divide both sides by 5:

$\frac{5\left(f-32\right)}{5}=\frac{9c}{5}$

$f-32=\frac{9c}{5}$

Add 32 to both sides:

$f-32+32=\frac{9c}{5}+32$

$f=\frac{9c}{5}+32$

Write an inequality that represents the graph.

Anika [276]

Answer:

$y - 2x - 1 = 0$

Step-by-step explanation:

the slope is :

$\tan( \alpha ) = 4 \div 2 = 2$

at a pt on graph , when

$x = 1 \\ y = 3 \\$

therefore, coordinates are (1,3)

The equation is :

$(y - 3) = slope \times (x - 1) \\ (y - 3) = 2 \times (x - 1) \\ y - 3 = 2x - 2 \\ y - 2x - 1 = 0$
