5 is the answer. Change the x for 2 but multiply. 2•2+7-3•2

2•2=4
3•2=6

4+7=11
11-6=5

5 is the answer to the expression.

A given line has the equation 10x 2y=−2 . what is the equation, in slope-intercept form, of the line that is parallel to the giv
aivan3 [116]

The equation, in slope-intercept form, of the line that is parallel to the given line and passes through the point (0, 12) is y = -5x + 1

<h3>Equation of a line</h3>

A line is the distance between two points

Given the equation of a line expressed as 10x + 2y = -2. Determine the slope

2y = -10x -2

y = -5x - 1

Slope of the line is -5

The equation of a line in point-slope form is y - y1 = m(x-x1)

Substitute the point and the slope of the parallel line

y - 12 = -5(x  - 0)
y - 12 = -5x
y = -5x + 12

Hence the equation, in slope-intercept form, of the line that is parallel to the given line and passes through the point (0, 12) is y = -5x + 12

Help me please I’ll donate money
Virty [35]

12. It's similar to having an infinite number of solutions because there isn't a specific solution to answer the question.

13. For the equation 0.9x + 5.1x - 7 = 2(2.5x-3), there is only one solution and it is x=1

14. The error that your friend made was that she added extra 16x to the equation. the correct answer is that there is no solution.

16. the equation  6 (x+2)= 5 (x+7) has only one solution. it is x=3.

sorry i wasn't able to answer the other 3,

by the way you don't need to send money, because we are here to help

Enter the inequality of the graph below.
aev [14]
The slope is (8-2)/(0-2)=-3
the y intercept is 8
the equation is y=-3x+8
the area to the left is shaded, and the line is solid, so y\leq-3x+8

On the previous problem, you found a unit rate of ounces per box. Explain how you find a unit rate when given a rate.
Afina-wow [57]

Answer:

A unit rate is a rate with 1 in the denominator. If you have a rate, such as price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.
