Answer:-1
Step-by-step explanation:
2 dollars gained in July 2 dollars gained in August and 5 dollars lost in September is -1
X (a + 2) = 7
First let's multiply out the brackets on the left side of the equation.
x (a + 2) --> Multiply everything inside the brackets by x.
xa + 2x = 7
Now, both elements of the left-hand side of the equation contain x, so we can divide both sides of the equation by x.
xa + 2x = 7
a + 2 = 7/x
To find a now, just subtract 2 from both sides.
a = 7/x - 2
Joe.. because -1 and 5 are in joes quardrent
Answer:
B.)
Step-by-step explanation:
In step #1 they did the distributive property
2/5 × 15x = 6x
2/5 × -30y = -12y
The new equation would be:
6x - 12y + 10x
<em><u>Further</u></em><em><u> </u></em><em><u>Explanation</u></em>
They then combined 6x + 10x to get 16x
16x - 12y
They then factored it out to 4(4x - 3y)
First, you need to find the slope of HI.
Find two points. (On the line)
(-5,5) (1,9) I’m just going to use the points for H and I.
Plug it into the slope formula.
M= (y2-y1)/(x2-x1)
M= (9-5)/(1-(-5) Switch the sign to be positive, two negatives equal a positive.
M= 4/6
Now, you just need to find the opposite reciprocal for the slope of the perpendicular line.
Flip 4 and 6. Make it negative.
-6/4
Simplify.
-3/2 or -1.5
I hope this helps!
