First you foil so you would get

0.5r+1.375=3

Then you subtract the 1.375 to the 3

0.5r=3-1.375

0.5r=2.375

Now to find r you need to divide by 0.5

r=2.375/0.5

0.5 (r + 2.75) = 3
0.5 r +1.375 = 3
0.5 r= 3 - 1.375
0.5 r= 1.625
r= 1.625/0.5
r = 3.25

Find the gradient and the intercept shown by the straight line 2x + 3y = 6

sveta [45]

Answer:

$\sf gradient =\dfrac{-2}{3}\\\\ y -intercept = 2$

Step-by-step explanation:

<h2>Equation of the line in slope intercept form:</h2>

$\sf \boxed{\bf y = mx +b}$

Here m is the slope or gradient and b is the y-intercept.

Write the given equation in slope-intercept form.

2x + 3y = 6

3y = -2x + 6

$\sf y =\dfrac{-2}{3}x +\dfrac{6}{3}\\\\ y = \dfrac{-2}{3}x + 2$

$\sf gradient =\dfrac{-2}{3}\\\\ y -intercept = 2$

Help me please I need it

koban [17]

Unfortunately, you inadvertently cut off the instructions for this problem when you photographed it. Could you try again, making certain to include the instructions?

Let me guess: perhaps the instructions are 1) determine the slope of the line passing through the given points, or 2) write the equation of the line passing through the given points.

If f(x) = 2x - 5 , Find f(3). <br> Substitute 3 for x then type your final answer.

Savatey [412]

Answer:

f(3)=1

Step-by-step explanation:

take f(x)=2(x)-5

put a three wherever you see an x in parentheses

f(3)=2(3) - 5

simplify

f(3)=6-5

simplify

f(3)=1

answer:f(3)=1

EMERGENCY!!!!!!!! I need help right now please

erastova [34]

Answer:

50 Degrees

Step-by-step explanation:

Since they already have 40 degrees for you, and a little square means a right angle (90 Degrees), then 40 + 90 is 130. The interior angles of a triangle always add up to 180, so 180 - 130 is 50. The answer is therefore 50 degrees.
