Answer:

seven-eighths of a number minus three

Step-by-step explanation:

the algebraic expression given to us is:

$\frac{7}{8} y-3$

we have seven-eighths multiplied by a number "y" (this can also be expressed as seven-eighths of the number) and then, to that we substract 3 (minus three).

With this information we can conclude that the phrase that best describes this expression is:

seven-eighths of a number minus three

which is the first option.

Slope of (-2,-1) and (5,-1) in fraction form

dangina [55]

Slope is 0

Step-by-step explanation:

Step 1: Find slope using the formula for slope, m = (y2 - y1)/(x2 - x1) Here, x1 = -2, y1 = -1, x2 = 5 and y2 = -1

⇒ m = (-1 - -1)/(5 - -2)

$6 \sin(x) - 3 \sqrt{2} = 0$

$6 \sin(x) = 3 \sqrt{2}$

$\sin(x) = \dfrac{3 \sqrt{2} }{6}$

$\sin(x) = \dfrac{ \sqrt{2} }{2}$

$\sin(x) = \dfrac{1}{ \sqrt{2} }$

$\large\boxed{x = 45° \: \: or \: \: 135°}$

2. A chemist has a 25% and a 50% acid solution. How

AnnZ [28]

Answer:

x is mL of 25% acid and y is mL of 50% acid

We set up 2 equations:

A) x + y = 250

B) .25 x + .50y = .35 * 250 which equals

B) .25x + .50y = 87.50 Multiplying A) by -.5

A) -.5x -.5y = -125 adding the equations we get

-.25x = -37.50

x = 150 mL

y = 100 mL
