Let $x$ be the number of items. Each takes 1/8 hour to purchase, so a total time of $\frac 1 8 x$ . If we have 3/4 hour, then

$\frac 1 8 x = \frac 3 4$

That's part a.

b. Multiplying by 8,

$x = \frac 3 4 (8) = 6$

c. We have time to by 6 items at 1/8 hour each in 3/4 hours.

VARVARA [1.3K]

Answer:

Hello,

answer B

Step-by-step explanation:

Vertex is (-3,-1)

(0,8) is a point of the parabola:

8=k*(0+3)²-1

8+1=9k

k=1

Equation is y=(x+3)²-1

(5.3a−0.8)−(1.6−4.7a)=2a−(a−0.3)

sammy [17]

Answer: a = 0.3

Step-by-step explanation:

First, distribute(-1)

5.3a-0.8-1.6+4.7a=2a-(a-0.3)

Then, distribute(-1)

5.3a-0.8-1.6+4.7a=2a-a+0.3

Then, combine like terms

10a-2.4=a+0.3

Then, add(2.4)

10a=a+2.7

Then, subtract(a)

9a=2.7

Then, divide(9)

a = 0.3

Hope it helps <3

What is the slope of P=(4.5,-1) Q=(5.3,2).

Ulleksa [173]

$\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
% (a,b)
P&({{ 4.5}}\quad ,&{{ -1}})\quad 
% (c,d)
Q&({{ 5.3}}\quad ,&{{ 2}})
\end{array}
\\\\\\
% slope = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{2-(-1)}{5.3-4.5}\implies \cfrac{2+1}{5.3-4.5}
\\\\\\
\cfrac{3}{0.8}\implies \cfrac{\frac{3}{1}}{\frac{08}{10}}\implies \cfrac{\frac{3}{1}}{\frac{4}{5}}\implies \cfrac{3}{1}\cdot \cfrac{5}{4}\implies \cfrac{15}{4}\implies 3\frac{3}{4}$
