a + b - c = 180

add both sides by c

a + b - c + c = 180 + c

simplifying

a + b = 180 + c

subtract 180 from both sides

a + b - 180 = 180 + c - 180

simplifying

a + b - 180 = c

Answer

c = a + b - 180

A) Complete the table of values for y = 2x + 3<br> x,,-2,,-1,,0,,1,,2,,3<br> y,,,?,,,1,,,,?,,?,,7,,?

polet [3.4K]

Answer:

Step-by-step explanation:

Because the slope of y = 2x + 3 is 2, y increases by 2 for every unit increase in x.

Substituting the given x-value -2 into y = 2x + 3 results in y = -1.

If we now increase x by 1, from -2 to -1, y increases by 2: the new

y value is y = -1 + 2 or y = 1. which agrees with the +1 in the list of y-values.

Again, y = ?,,,1,,,,?,,?,,7,,? becomes y = -1, 1, ?,,?,,7. Note that -1 + 2 = 1;

1 + 2 = 3; 3 + 2 = 5; 5 + 2 = 7 (which agrees with the given 7); 7 + 2 = 9.

So the given incomplete table of values

x,,-2,,-1,,0,,1,,2,,3

y,,,?,,,1,,,,?,,?,,7,,?

becomes:

x,,-2,,-1,,0,,1,,2,,3

y,,, -1,,1,,,3,,5,,7,,9

Solve log 2x^2 + 2 = 6. Round to the nearest thousandth if necessary.

o-na [289]

Answer:

x = 70.71

Step-by-step explanation:

log 2x² + 2 = 6.

log 2x² + log 100= log 10⁶.

2x² × 100 = 10⁶

2x² = 10⁶/100

2x² = 10⁴

x² = 10⁴/2

x² = 5000

x = √5000

x is approximately 70.71

x = 70.71
