Answer:
-1/13
Step-by-step explanation:
The slope of a line is calculated as rise/run.
The rise is the difference in y-values, and the run is the difference in x values
slope= y₂ - y₁/x₂ - x₁
let (26 , 7) be (x , y) and (-39 , 12) be (x₂, y₂)
slope= (12 - 7)/ (-39 -26)
= 5/-65
reduce the fraction to get -1/13

what is the vertex of a parabola represented by the equation f(x) = -2 (x-4)^2 - 7
Answer:
f ( x ) = x ^2 + 1
f ( x ) = 7 x^ 2 + 5 x − 4
f ( x ) = 4 ( x − 3 ) ^2

The volume of a cylinder is 196in.3 and the height of the cylinder is 1 in. What is the radius of the cylinder?
Answer:
r ≈ 7.9 inches
Step-by-step explanation:
V(cylinder) = πr²h
196 = πr²(1)
196/π = r²
62.4 = r²
√62.4 = r
r ≈ 7.9

Felipe’s solution to an equation is shown below:
Given: x^2+6x+8=0
Step 1: (x+2)(x+4)=0
Step 2: x+2=0 or x+4=0
Step 3: x= -2 or x= -4
Which property of real numbers did Felipe’s use for step 2?
A. Distributive property of multiplication over addition
B: Multiplication property of equality
C. Commutative property of multiplication
D: Zero product of multiplication
Answer:
D. Zero product of multiplication
Step-by-step explanation:
The given equation is presented as follows;
Given: x² + 6·x + 8 = 0
By factorization, to find numbers represented by variables, 'a' and 'b', such that a + b = 6 and a×b = 8, we have, a = 2, and b = 8 as a possible solution by observation
Step 1: (x + 2)·(x + 4) = 0
Given that (x + 2) × (x + 4) = 0, we have
Step 2: x + 2 = 0 or x + 4 = 0, by zero product of multiplication
The zero-product property states that the when two non zero numbers are multiplied, the result is nonzero
Therefore, when two numbers are multiplied, and have a result of zero, for example, i × j = 0, then, either, i = 0, or j = 0
By the zero-product rule, either, (x + 2) = 0, or (x + 4) = 0
Therefore, we have;
Therefore;
Step 3: x = -2 or x = -4
The property of real numbers Felipe's use for step 2 is the Zero product of multiplication.
Line l has a _____ slope.
negative
0
positive
undefined
Answer:
positive
Step-by-step explanation:
negative slopes go from right to left; this line goes from left to right
0; the line isn't completely horizontal
undefined; the line isn't completely vertical
Using the function f (x) = 400 – 15x, where f(x) = the remaining pounds of grain in the truck, and (x) represents the amount of buckets taken out:
Calculate how many buckets it will take until their is 50 pounds of grain remaining.
Answer:
[tex]{ \tt{f(x) = 400 - 15x}} \\ { \boxed{ \tt{when \: f(x )\: is \: 50}}} \\ 400 - 15x = 50 \\ 15x = 400 - 50 \\ 15x = 350 \\ x = 23.3 \approx23 \: buckets \\ \\ { \underline{ \blue{ \tt{becker \: jnr}}}}[/tex]

How many liters are equal to 3,167 milliliters? Use the placement of the decimal point when dividing by a power of 10 to help you solve.
Answer:
3.167 liters
Step-by-step explanation:
1 liter = 1,000 milliliters
3,167 milliliters * 1liter/1,000milliliters = 3.167 liters
Find the center and radius of the circle whose equation is x 2 + y 2 - 6x - 2y + 4 = 0
(3,1), r = /6
(-3,-1), r = /6
(3,1) r = 6
(9,1), r = 36
Answer:
Solution given:
the equation of a circle is:
x²+y²-6x-2y+4=0
x²-2*x*3+3²+y²-2y+1²-1²+4=0
(x-3)²+(y-1)²=9+1-4
(x-3)²+(y-1)²=6
comparing above equation with
(a-h)²+(y-k)²=r²
we get
centre (h,k)=(3,1)
radius=√6
option first

the sum of the three numbers is 94. The second number is 2 times the third. The first number is 6 more than the third. what are the numbers?
Answer:
28, 44, 22
Step-by-step explanation:
a+b+c = 94
2×c = b
a = c+6
=>
c+6 + 2×c + c = 94
4×c + 6 = 94
4×c = 88
c = 22
=>
b = 2×22 = 44
a = 22 + 6 = 28
32x + 26 = -11 can someone help pls Ik in summer school
Answer:
x = -37/32
Step-by-step explanation:
32x + 26 = -11
Subtract 26 from each side
32x + 26-26 = -11-26
32x = -37
Divide each side by 32
32x/32 = -37/32
x = -37/32
Answer:
x= -1 5/32 or x=-1.15625

Pam has 228 ounces of lemonade. She pours the lemonade into
8-ounce cups, filling as many as she can until all the lemonade is
gone. The last cup is not completely full. How much lemonade is
in the last cup?
Answer:
4 ounces
Step-by-step explanation:
If you divide 228 by 8, you will get 28.5. The 0.5 into a fraction would be 1/2. Half of 8 would be 4. In the end, there should be 28 full 8-ounce cups and one cup with 4 ounces.
