She should have added 2 to both sides of the equation instead of subtracting 2.

2x -2 = 14

Add 2 to both sides:

2x = 16

Divide both sides by 2:

x = 8

The Hurry-Mart convenient store is re-stocking their shelves. They always stock the m&m to Hershey bars at a ratio of 10 to

castortr0y [4]

Answer:

12 Hershey bars

Step-by-step explanation:

if its 10 to 8 and you have 15 m&m then you would have to do the 10 which you would have to put 8 then 5 is half of 10 so you would just half 8 which is 4 so 8+4+12. 12 Hershey bars needed to restock the shelf.

Answer:

s= 15 (nearest integer), 14.8 (to nearest 10ths)

Step-by-step explanation:

here you need to apply the cosine rule,

${s}^{2} = {u}^{2} + {t}^{2} - 2ut \cos(s)$

substituting the values,

u= 13, t=5 and angle S as 60 and solving will give you the answer 14.76 (2 dp)

Wright in point-slope form, slope-intercept form and in standard form an equation that passes through (-1, 2) with slope 4

SOVA2 [1]

Answer:

$\textsf{Point-slope form}: \quad \sf y-2=4(x+1)$

$\textsf{Slope-intercept form}: \quad \sf y=4x+6$

$\textsf{Standard form}: \quad \sf 4x-y=-6$

Step-by-step explanation:

Given information:

Slope = 4
Point on line = (-1, 2)

Point-slope form of linear equation:

$\sf y-y_1=m(x-x_1)$

(where m is the slope and (x₁, y₁) is a point on the line)

Substitute the given slope and point into the formula:

$\implies \sf y-2=4(x-(-1))$

$\implies \sf y-2=4(x+1)$

Slope-intercept form of a linear equation:

$\sf y=mx+b$

(where m is the slope and b is the y-intercept)

Substitute the given slope and point into the formula and solve for b:

$\implies \sf 2=4(-1)+b$

$\implies \sf b=6$

Therefore:

$\sf y=4x+6$

Standard form of a linear equation:

$\sf Ax+By=C$

(where A, B and C are constants and A must be positive)

Rearrange the found slope-intercept form of the equation into standard form:

$\implies \sf y=4x+6$

$\implies \sf 4x-y+6=0$

$\implies \sf 4x-y=-6$
