Find the slope.
y = -3x - 2
m =
= [?]
Answer:
slope m=--3/-2=-3/2 is required slope
Answer:
m = -3, b = -2
Step-by-step explanation:
The equation is written in the form of slope-intercept, where m = slope and b = y-intercept.
The slope is the number before x. For the equation y = -3x - 2, it's -3.
The y-intercept is the constant. For the equation y = -3x - 2, it's -2.
Hence, m = -3, and b = -2.

In a shipment of 400 parts, 14 are found to be defective. How many parts out of 1000 would NOT be defective?
Can you please show a proportion I am confused.
Answer:
965 parts would not be defective.
Step-by-step explanation:
So for every 400 parts, 14 are defective. That means 386 are not defective. 1000 is 2.5 times as many as 400. So multiply 386 by 2.5 to get your answer.
386/1 * 5/2
193/1 * 5/1
965/1
That means for every 1000 parts, 965 would not be defective. The proportion(s) would be 386:400/965:1000 here.

What is the quotient of 2.592\times 10^72.592×10 7 and 7.2 \times 10^47.2×10 4 expressed in scientific notation?
The quotient, expressed in scientific notation, is:
Quotient = 0.36 × 10³
Given:
(2.592 × 10⁷) / (7.2 × 10⁴)
To find the quotient of 2.592 × 10⁷ and 7.2 × 10⁴ and express it in scientific notation, we divide the coefficients and subtract the exponents.
Quotient = (2.592 × 10⁷) / (7.2 × 10⁴)
Dividing the coefficients, we get:
Quotient = 2.592 / 7.2 = 0.36
Subtracting the exponents, we get:
10⁷ - 10⁴ = 10⁽⁷⁻³⁾ = 10³
In scientific notation, the coefficient should be between 1 and 10, so we can rewrite the expression as:
Quotient = 0.36 × 10³

Teammates Pedro and Ricky got 2679 base hits last season. Pedro had 281 more hits than Ricky.
How many hits did each player have?
9514 1404 393
Answer:
Pedro: 1480Ricky: 1199Step-by-step explanation:
Let r represent the number of hits Ricky got. Then Pedro's hits were r+281 and their total was ...
r + (r +281) = 2679
2r = 2398
r = 1199
r+281 = 1480
Pedro got 1480 hits; Ricky got 1199.
_____
Additional comment
The two answers to a "sum and difference" problem are half the sum plus or minus half the difference. Here, those values are (2679/2) ± (281/2). Pedro got more hits, so his number is (2679+281)/2 and Ricky's number is (2679-281)/2, as above.

8 - 4a = -2a
7th Grade Linear Questions
Answer:
a = 4
Step-by-step explanation:
So your goal here is to get the variable on just one side, so add 4a to both sides. This cancels out the 4a on of of the sides and puts a on the other side. The new equation is 8 = -2a + 4a. Combine like terms to get 8 = 2a. Divide both sides by 2 to get a = 4. You can check your work by replacing a with 4:
8 - 4(4) = -2(4)
8 - 16 = -8
-8 = -8
Since the final result is true, (-8 does equal -8,) a = 4.

A. 100 units
B. 14 units
C. 2 units
D. 10 units
Answer:
D. 10 units
Step-by-step explanation:
Using the distance formula:
d = √(x2 – x1)² + (y2 – y1)²
Plug in the values of the points:
d = √(3 – (-5))² + (-2 – 4)²
d = √(8)² + (-6)²
d = √64 + 36
d = √100
d = 10
