Which is the best first step when solving the following system of equations? x + y = 3. 4 x minus y = 7. Multiply the first equa
____ [38]

Answer:

just add the equation and solve it then the value of X could be found then put the value of X and the value of y can be found. Just like in the below

Step-by-step explanation:

X+y=3 ------------ equation 1

4x-y=7 ------------ equation 2

adding equation 1 and 2

X+y=3

+ 4x-y=7

-----------------

5x = 10

X = 10/5

X = 2

putting the value of X in equation 1

or, 2+y=3

or, y = 3-2

Thus, y = 1

1. A line passes through (9, -9) and (10,-5).
jenyasd209 [6]

Answer:

1. y+5=4x-40

2.y=4x-45

Step-by-step explanation:

To get the slope of a line you do y₂-y₁/x₂-x₁ so we plug in the values -9+5/9-10 and we get -4

Point-slope form states y-y₁=m(x-x₁) where m is the slope so plug in the values we get y+5=4(x-10) and you get y+5=4x-40 then turn this equation into y=mx+b and get y= 4x-45

Notice that the three angles add up to cover half a circle (therefore 180 degrees of angle. Such type of angle combination is called a "linear triplet" since they add up to give a straight line.

Sue drank 2/5 of her water bottle and sally drank 4/10 of her water bottle how much water did both girls drank?
stealth61 [152]

well, clearly the LCD from the denominators of 5 and 10 is just 10, thus

\bf \stackrel{\textit{Sue}}{\cfrac{2}{5}}+\stackrel{\textit{Sally}}{\cfrac{4}{10}}\implies \stackrel{\textit{LCD of 10}}{\cfrac{(2)2~~+~~(1)4}{10}}\implies \cfrac{2+4}{10}\implies \cfrac{6}{10}\implies \stackrel{\textit{simplified}}{\cfrac{3}{5}}

A car leaving a stop sign accelerates...what is the average speed of the car, in feet per second, equation d=1.1t^2 average spee
spayn [35]

Answer:

10.27 feet/sec.

Step-by-step explanation:

The distance traveled by the car, d in feet, is given by the function d = 1.1t^{2} .......... (1), where t is the time in seconds.

So, at t= 2 sec, from equation (1) we get d = 1.1 × 4 = 4.4 feet.

Again, at t = 5 sec, we get d = 1.1 × 32 = 35.2 feet.

Now, average speed of the car from t = 2 sec. to t = 5 sec. will be give by

\frac{\textrm {Total distance traveled}}{\textrm {Total time spent}}

= \frac{35.2 - 4.4}{5 - 2} = 10.27 feet/sec. (Answer)
