-x + y = 5
x - 5y = 2 ---> x= 5y + 2
I have solved the second equation for x. What is the next step if solving this system with substitution?
A. -(5y+2) + y = 5
B. -x + y = 5 + 5y + 2
C. None of the Above
D. -x + 5y + 2 = 5
Answer:
A. -(5y+2) + y = 5
Step-by-step explanation:
Solving the above Equation given to us in the Question,
-x + y = 5...... Equation 1
x - 5y = 2....... Equation 2
Step 1
We make x subject of the formula in Equation 2
---> x= 5y + 2
Step 2
This would be to substitute 5y + 2 for x in Equation 1
-x + y = 5...... Equation 1
-(5y+2) + y = 5
Hence, Option A is the correct option

Write an equation in slope-intercept form which has a slope of 1/4 and crosses the Ÿ-axis at (0,7)
Answer:
y= 1/4 x +7
Step-by-step explanation:
The slope intercept form of a line is
y = mx + b where m is the slope and b is the y intercept
the slope is 1/4 and the y intercept is 7
y= 1/4 x +7

Step 1: Define
We are given a right triangle. We can use PT to solve the missing length.
Step 2: Identify Variables
Leg a = √27
Leg b = 15
Hypotenuse c = x
Step 3: Solve for x
Substitute [PT]: (√27)² + 15² = x²Exponents: 27 + 225 = x²Add: 252 = x²Isolate x: 6√7 = xRewrite: x = 6√71. A right triangle is shown.

Help me with this question! Will mark brainliest
Answer:
D) y = 7x + 1
Step-by-step explanation:
Slope-incercept form is y = mx + b in which m = slope and b = y-incercept
The line crosses through (0,1), which means the y-intercept is 1
Plug the given numbers into that formula:
y = 7x + 1

The length of the deck is 3 times it’s width. If the decks perimeter is 16 ft what is the decks area
Answer:
12 ft²Step-by-step explanation:
Givenl = 3wP = 16A = ?SolutionUse perimeter formula
P= 2(l + w) = 2(w + 3w) = 8wFind width:
8w = 16 ⇒ w = 2 ftFind length:
l = 3*2= 6 ftFind area:
A = lw = 6*2 = 12 ft²John bought a play station game for $54.50. The tax on the game is 5%. What

Answer:
1089/20 (Decimal: 54.45)
Answer:
$57.22
Step-by-step explanation:
$2.72 would be 5% of 54.50
The total cost would be
54.50 + 2.72
that would equal
57.22

Answer:
[tex]m=\frac{225-135}{5-3} =\frac{90}{2}[/tex]
Step-by-step explanation:
OK i am glad to help.
Slope is [tex]\frac{y2-x2}{y1-x1}[/tex]
So, in the boxes, it is
[tex]\frac{225-x2}{y1-3}[/tex]
Our points are
5,225 and
3,135 so the slope should be
[tex]\frac{225-135}{5-3}[/tex]
This is the answer for the first box.
Second is

What is the slope of the line do the point for me to?
Answer:
Step-by-step explanation:
we can see that the line goes thru the point (-1,2) and (4,-2) now to find slope we just find change in y over change in x
more visually:
(y1-y2)/(x1-x2)
so for the point (-1,2) let’s say
-1 = x1
and
2 = y1
and for the point (4,-2) let’s say
4 = x2
and
-2 = y2
to find slope we plug in the values to our slope equation and we get this:
(2-(-2))/( -1-4)
(2+2)/-5
4/-5
so slope is -4/5
because to get from (-1,2) to (-4,-2) you have to move down 4 and to the right 5
Find the value of x
is this correct?
Answer:
Yes
Step-by-step explanation:
Answer:
yes
Step-by-step explanation:
3(x+2) = 24 (because it’s an isosceles so both sides are equal)
x+2 = 24/3
x +2 = 8
x = 8-2
x = 6
Considerando las siguientes variables a = ancho y l = longitud, determina su valor, si se sabe que se cuenta con un rectángulo que tiene como perímetro 35 metros, y se sabe que el doble de su ancho es igual a 3 veces su longitud.
Answer:
La longitud = 7 metros
La anchor = 10.5 metros
Step-by-step explanation:
La fórmula para el perímetro de un rectángulo es
P = 2L + 2W
L = longitud
A = ancho
P = 35 metros
se sabe que el doble de su ancho es igual a 3 veces su largo.
2A = 3L
Ancho = 3L / 2 = 1.5L
Sustituimos 1.5L por W
35 = 2 L + 2 (1.5 L)
35 = 2L + 3L
35 = 5 litros
L = 35/5
L = 7 metros
Por lo tanto, la longitud = 7 metros
Recuerda
A = 1.5 L
A = 1.5 × 7
A = 10.5 metros
La anchor = 10.5 metros
Micah who is not yet 15 years old, is two years older than DeMonte.
How old is DeMonte?
x = the age of Micah
y = the age of DeMonte
Answer:
DeMonte is 12
Step-by-step explanation:
If Micah is not yet 15 than he is 14 so 14 - 2 is 12 since DeMonte is two years younger than Micah.
