What is the solution to −1/4(d+1)<2
kogti [31]

Answer:

d > -9

Step-by-step explanation:

-\dfrac{1}{4}(d + 1) < 2

First, multiply both sides by -4. You must also change the inequality sign since you are multiplying both sides by a negative number.

-4 \times \left(-\dfrac{1}{4}\right)(d + 1) > 2 \times (-4)

d + 1 > -8

Subtract 1 from both sides.

d + 1 - 1 > -8 - 1

d > -9

lily swims a 100-meter race. she swims the first half in 27.8 seconds. she swims the second half in 30.12 seconds. how long does
Luden [163]

we know that

1) Lily swims a 100-meter race

2) She swims the first half in 27.8 seconds

3) She swims the second half in 30.12 seconds

so

To find the total time to swim the whole race sum the time in the first half plus the time in second half

(27.8+30.12)=57.92\ seconds

therefore

<u>the answer is</u>

57.92\ seconds

What function corresponds to the ordered pairs shown in the table?
Anettt [7]

well, we know it's a line, and to get the equation of any line all we need is two points, let's pick two from the table hmmmm say let's use (-3 , -7) and (3 , 11)

(\stackrel{x_1}{-3}~,~\stackrel{y_1}{-7})\qquad (\stackrel{x_2}{3}~,~\stackrel{y_2}{11}) \\\\\\ \stackrel{slope}{m}\implies \cfrac{\stackrel{rise} {\stackrel{y_2}{11}-\stackrel{y1}{(-7)}}}{\underset{run} {\underset{x_2}{3}-\underset{x_1}{(-3)}}}\implies \cfrac{11+7}{3+3}\implies \cfrac{18}{6}\implies 3

\begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-7)}=\stackrel{m}{3}(x-\stackrel{x_1}{(-3)}) \\\\\\ y+7=3(x+3)\implies y+7=3x+9\implies y = 3x+2
