Answer:
y=−4
Step-by-step explanation:
Let's solve your equation step-by-step.
7y−4=−32
Step 1: Add 4 to both sides.
7y−4+4 =−32+4
7y =−28
Step 2: Divide both sides by 7.
7y/7 = −28/7
y=−4
(/:divide) Hope it helps!!
when a=4 and b=3,
3.14((4 x 2)+ (4 x 3)) = 3.14(8+12) = 3.14 x 20 = 62.8
Answer:
C) an obtuse triangle
Step-by-step explanation:
Since the main angle (the angle that corresponds to the longest side) is considered to measure more than 90°, it is an obtuse triangle.
a) the cost of a bunch of grapes compared with its weight
Answer:
y = 3x + 7
Step-by-step explanation:
Parallel lines have the same slope, so you can write the equation y = 3x + b and you have to figure out what b is.
plug in x = -3 and y = -2 into the equation y = 3x + b:
-2 = 3 * -3 + b
-2 = -9 + b
7 = b
So the equation is y = 3x + 7
