Answer:

71

Step-by-step explanation:

Because this triangle is an isosceles, the base angles are equal

the top angle is 38 and triangles add up to 180

so 180-38=142

then divide that by 2

which is 71 so x=71

Triangle ABC has vertices at A(-3,4)B(4,-2)C(8,3).The triangle is translated 4 units down and 3 units left . Which rule represen
FinnZ [79.3K]

Answer:

see explanation

Step-by-step explanation:

A translation of 4 units down means subtract 4 from the y- coordinate of the original point and a translation of 3 units left means subtract 3 from the original x- coordinate, thus translation rule is

(x, y ) → (x - 3, y - 4 )

Thus

C(8, 3 ) → C'(8 - 3, 3 - 4 ) → C'(5, - 1 )

The graph represents the speed at which Pete’s marble travels.
AfilCa [17]

Answer:

B

Step-by-step explanation:

Here, we simply want to know who will reach the 6-foot mark sooner

Mathematically, we need to get the slope from the graph

Looking at the graph, we can see that the 3 ft mark was reached at exactly 2 seconds

So what this mean is that, in 4 seconds, the 6 ft mark will be reached

This makes up the fact that the speed for Pete’s travel is 1.5 ft/ secs

Now compare this with what Stephano has, which is 2.25 ft/ s

we can see that stephano is traveling at a better speed and will reach the 6 ft mark first

So the correct option is B

I need help please help me ‼️‼️‼️‼️‼️
motikmotik

Answer:

A, m < $69.43

Step-by-step explanation:

(Could be wrong, I'm just browsing through brainly and thought it looked easy)

I found the percentage of what they've raised by doing 552.5 * .12 (12 percent of 552.5)

This gave me 66.3

We now need to look for how much they need to raise, so you subtract 552.5 by 66.3 to get 486.2.

You need to find out how much each of the 7 members needs to raise to get 486.2, to do this divide 486.2 by 7 to get 69.45.

Ideally, they would raise just this amount and the correct answer would be an equal sign, but since that isn't an option and if they raised less than 69.45 individually they would fail, raising more than 69.45 would pass their goal. So A, more than 69.45 is the answer.

How would you solve 5x+3y=12 by graphing it?
Crank
First you must get y by itself and then set it up in slope intercept form: y=mx+b where m is the slope, b is the y intercept, and y is what it equals too
