3 Find y if the slope between ( – 7, y) and (1, 13) is 3/4
Answers
Step-by-step explanation:
[tex]slope \: = \frac{y2 - y1}{x2 - x1} = \frac{3}{4} [/tex]
point 1 ( -7,y)
point 2 (1,13)
[tex] \frac{13 - y1}{1 - ( - 7)} = \frac{3}{4} [/tex]
[tex] \frac{13 - y1}{8} = \frac{3}{4} [/tex]
[tex]13 - y2 = \frac{8 \times 3}{4} = 6[/tex]
[tex]y2 = 13 - 6 = 7[/tex]

Maggie's brother is 4 years younger than twice her age. The sum of their ages is 29.
How old is Maggie?
Maggie is____
years old.
Answers
Answer:
11
Step-by-step explanation:
You have to make a system of equations. So the first equation would be b=2m-4 (b is brother m is maggie). The next equation is 29=m+b (sum of their ages). Then you can use substitution so plug in 2m-4 for b in the second question. So it would be 29=m+2m-4. Simplify and solve for m and you get 11.

Solve for x 4(x + 2) = 3 (x - 2)
Answers
Answer:
x = -14
)Step-by-step explanation:
To find the value of x
Transpose
4(x + 2) = 3 (x - 2)
4x + 8 = 3x - 6
4x - 3x = -6 -8
x = -14
we can even cross check
putting the value of x by -14
4(x + 2) = 3 (x - 2)
4 (-14 +2) = 3 (-14 -2)
-56 +8 = -42 -6
-48 = -48
same = same
so CROSS-CHECKED
Answer:
x = -14
Step-by-step explanation:
4(x + 2) = 3 (x - 2)
4x + 8 = 3x - 6
x + 8 = -6
x = -14

The hypotenuse of a right triangle is 10 meters and its
legs measure x and x + 2. How long are the legs?
Answers
Let's solve by using Pythagoras theorem,
[tex] \hookrightarrow \: (10) {}^{2} = {(x})^{2} + (x + 2) {}^{2} [/tex]
[tex] \hookrightarrow \: 100 = {x}^{2} + {x}^{2} + 4x + 4[/tex]
[tex] \hookrightarrow \: 100 - 4 = 2 {x}^{2} + 4x[/tex]
[tex] \hookrightarrow \: 96 = 2 {x}^{2} + 4x[/tex]
[tex] \hookrightarrow \: 2 {x}^{2} + 4x - 96 = 0[/tex]
[tex] \hookrightarrow \: 2( {x}^{2} + 2x - 48) = 0[/tex]
[tex] \hookrightarrow \: {x}^{2} + 2x - 48 = 0[/tex]
[tex] \hookrightarrow \: {x}^{2} + 8x - 6x - 48 = 0[/tex]
[tex] \hookrightarrow \: x(x + 8) - 6(x + 8) = 0[/tex]
[tex] \hookrightarrow \: (x + 8)(x - 6) = 0[/tex]
now there are two cases
Case 1 : when (x + 8) = 0
[tex] \hookrightarrow \: x + 8 = 0[/tex]
[tex] \hookrightarrow \: x = - 8[/tex]
but the value of x can't be negative, since side of a triangle isn't a negative value .
Case 2 : when (x - 6) = 0
[tex] \hookrightarrow \: x - 6 = 0[/tex]
[tex] \hookrightarrow \: x = 6[/tex]
therefore the measure of other two sides are :
[tex] \hookrightarrow \: x = 6 \: units[/tex]
[tex] \hookrightarrow \: x + 2 = 6 + 2 = 8 \: units[/tex]

hi <3
we need to form an equation
lets call our unknown number 'x'
so now we have:
2x + 5 = 15
subtract 5 from both sides
2x = 10
divide both sides by 2 to get your answer of:
x = 5
