Evaluate y5 + x(-7) When x = 2, y = -5

Mathematics
1 answer:
Ymorist [56]3 years ago
3 0

Answer:

45

Step-by-step explanation:

OK, first we turn the variables into into the actual values:

The equation will look like this:

(2)5 + (-5)(-7)

Now its easier to solve!  Lets solve (2)5!

2 * 5 = 10

The equation looks like:

10 + (-5)(-7)  

We will also solve (-5)(-7). Remember that a negative number times a negative number is positive!

-5 * -7 = 35

Lets finish the rest:

10 + 35 = 45.          

Hope this is correct and have a nice day!

Given h(t)=-2(t+5)^2+4, find h(-8)<br><br> -334<br> -14<br> -45<br> -445
stepladder [879]

Substitute -8 for t in the expression, and now you have: h(-8) = -2[(-8) + 5]^2 + 4. Solve inside the parentheses; add -8 and 5.

h(-8) = -2[-3]^2 + 4, solve exponents next by squaring -3.

h(-8) = -2[9] + 4, multiply -2 and 9.

h(-8) = [-18] + 4, add -18 and 4.

h(-8) = -14.

pickupchik [31]
100% - (39% + 28% + 13%) = 100% - 80% = 20%
so 20% are watermelons.

20% of 1505...
0.20(1505) = 301

so 301 are watermelons
