The equation of line EF is y = 2x + 1. Write an equation of a line parallel to line EF in slope-intercept form that contains poi
77julia77 [94]

Answer:  The answer is (b) y=2x+2.


Step-by-step explanation:  The equation of a straight line in slope-intercept form is given by

y=mx+c, where, 'm' is the slope and 'c' is the y-intercept of the straight line.

The equation of the given line EF is

y=2x+1.

Here, slope, m=2 and y-intercept, c=1.

Since our new line is parallel to the given line, so the slope of the new line=m=2.

So, let the equation of the new line be

y=mx+d\\\\\Rightarrow y=2x+d.

Now, since the line passes through the point (0,2), so

2=2\times 0+d\\\Rightarrow d=2.

Thus, the equation of the new line parallel to line EF will be

y=2x+2.

The correct option is (b).

Solve with subsitution <br> y-3x=2<br> y=-2x-8 <br> show ur work HURRY PLSS
IRINA_888 [86]

Answer:

y-3x=2......1

y=-2x-8 ......2

substituting value of y in equation 1

-2x-8-3x=2

-5x=2+8

x=10/-5=-2

substituting value of x in equation 1

y-3×(-2)=2

y+6=2

y=2-6=-4

x=-2

y=-4

12 times a number decreased by 5 is no more than 55
lions [1.4K]

Answer:

  12n -5 ≤ 55

Step-by-step explanation:

12 times a number (represented by n) is 12n.

"Decreased by 5" means 5 is subtracted from the product, giving 12n-5.

"Is no more than 55" means "is less than or equal to 55".

Then the expression written using math symbols is ...

  12n -5 ≤ 55

Deon has to buy all the butter she needs to make 60 biscuits. She buys the butter in 250 g packs. (b) How many packs of butter d
Vikki [24]

Answer:

200g of sugar, 600g of flour, 400g of butter

Step-by-step explanation:

50g sugar = 15 biscuits

3 x 50g = flour --) 150g = flour

2 x 50g = butter --) 100g = butter

60/15 = 4; 4 times as much

4 x 50g = 200g of sugar

4 x 150g = 600g of flour

4 x 100g = 400g of butter
