Answer:

16 pencils and 17 glue sticks

Step-by-step explanation:

X=pencils

Y=glue sticks

X+Y=33

1.50X+2Y=58

times ten to get whole numbers

=15X+20Y=580

same for e1

=10X+10Y=330

15X+20Y=580

10X+10Y=330

elimination mthd

150X+200Y=5800

150X+150Y=4950

50Y= 850

<u>Y</u><u>=</u><u>1</u><u>7</u>

<u>X</u><u>+</u><u>17</u><u>=</u><u>3</u><u>3</u>

X=33-17

X=16

Help asap plz ill give a gold medal. the label on cars antifreeze claims to protect the car between -30celsius and 130celsius. t

The inequality would start out looking like this:
-30\ \textless \  \frac{5}{9} (F-32)\ \textless \ 130
Now it's just a matter of solving the inequalities simultaneously. Get rid of the fraction by multiplying everything by 9:
-270\ \textless \ 5(F-32)\ \textless \ 1170
Then distribute the 5 into the parenthesis:
-270\ \textless \ 5F-160\ \textless \ 1170
Now add 160 everywhere:
-110\ \textless \ 5F\ \textless \ 1330
and finally divide everything by 5:
-22<F<266

The function f(x) = –2/7(5/3)^x is reflected over the y-axis to create g(x). Which points represent ordered pairs on g(x)? Check
Andreyy89
Given:
f(x)=- \frac{2}{7} ( \frac{5}{3} )^{x}

We are given ordered pairs of values for g(x) whose x-values are
-7, -2.5, 0, 0.5, 4, and 9.

After reflection across the x-axis, f(x) should have negative x-values, but the same y-values.
Use the calculator to create a table of f(x), with x-values of
7, 2.5, 0, -0.5, -4, and -9. 

x:               7        2.5            0      -0.5         -4          -9
f(x):  -10.206   -1.025  -0.286   -0.221  -0.037  -0.003

The corresponding values for g(x) will match f(x), but the x-values will be multiplied by -1.

Answer:
Of the given answers, only these are correct:
(-7, -10.206)
(0.5, -0.221)
(9, 0.003)
