Solving systems of equations using substitution with both equations in y=mx+b PLEASE HELP ME I WILL GIVE BRAINLIEST. I WILL HAVE TO DO APE.X IF I DONT GET THESE RIGHT. THANKYOU!
1.
y = x + 11 y = 1 + 11
y = 12x y = 12
x + 11 = 12x
11 = 11x
x = 1
(1, 12)
2.
y = 2x - 1
y = x + 1
2x - 1 = x + 1
x = 2
y = 2(2) - 1
y = 3
(2, 3)
3.
4x + 6 = 2x +2
2x = - 4
x = -2
y = 2(-2) + 2
y = -2
(-2, -2)
4.
-4x + 10 = -2x
-2x = - 10
x = 5
y = - 10
(5, -10)
5.
3x - 2 = -2x + 3
5x = 5
x = 1
y = 1

11. The slope of a line is 1/5. Label the two right
triangles with dimensions that would allow the
triangles to lie on the same line.
Answer:
Step-by-step explanation:
If the slope is 1/5, we can interpret this as rise/run = 1/5. We could (if we wished to do so) find the hypotenuse by using the Pythagorean Theorem:
hypo = +sqrt( 1^2 + 5^2)
In this case we dilate the triangle defined by the slope 1/5:
2/10, 1/10/(1/2), 10/50, etc., all represent right triangles whose hypotenuses lie on the same line (the line with slope 1/5).
The two right triangles are shown in the graph
What are coordinates?The coordinates in rectangular cartesian system are of the form -
(x, y)
where -
{x} - distance along x - axis.
{y} - distance along y - axis.
Given is the slope of the line as - {m} = 1/5.
Refer to the graph attached. The line -
y = (1/5)x
is plotted. It can be seen that (0, 0) and (10, 2) lie on the line. For two right triangles to lie on the same line, draw two perpendiculars from point (10, 2) along the {x} axis and {y} axis. Refer to the triangles shown in the graph.
Therefore, two right triangles are shown in the graph.

Pythagorean theorem - please help
answer:
x = 4[tex]\sqrt{2}[/tex] or 5.6568
step-by-step explanation:
know the formula and plug informula: a^2 + b^2 = c^2
now plug in what we havewhatever the RIGHT ANGLE points to is the HYPOTENUSE or cthe other two sides are the "legs" or a and ba^2 + b^2 = c^2
7^2 + b^2 = 9^2
49 + b^2 = 81
b^2 = 32
b = 4[tex]\sqrt{2}[/tex]
in this case, b would be used as xx = 4[tex]\sqrt{2}[/tex] or 5.6568 (exact value)

Find the distance between C(-5,4) and Q(2,0)
9514 1404 393
Answer:
√65 ≈ 8.06
Step-by-step explanation:
The distance formula is used for the purpose.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((2 -(-5))² +(0 -4)²) = √(7² +(-4)²) = √(49 +16)
d = √65 ≈ 8.0622577
The distance between C and Q is √65, about 8.06 units.

DE^2=2.5^2+3^2
DE^2=6.25+9
DE^2=15.25
DE=3.91
CD^2=3^2+5^2
CD^2=9+25
CD^2=34
CD= 5.83
BC^2=4^2+3^2
BC^2=16+9
BC^2=25
BC=5
AB^2=5^2+2^2
AB^2=25+4
AB^2=29
AB=5.39
