Answers
Answer:
B. f(-4) = g(-4), and f(0) = g(0)
Step-by-step explanation:
We are given two functions that have been graphed already. The points on the coordinate plane where the curve of g(x) intercepts that of f(x), are the values of x for each function, that would give us the same output (y).
Thus, for f(x) intercepts g(x) at the point where x = -4, y = 4.
Also, f(x) and g(x) intercepts at the point where x = 0, y = 4.
Therefore, the correct answer is f(-4) = g(-4), and f(0) = g(0)
PLEASE ANSWER RN PLSSS Two negative integers are 8 units apart on the number line and have a product of 308. Which equation could be used to determine x, the smaller negative integer? x2 + 8x – 308 = 0 x2 – 8x + 308 = 0 x2 + 8x + 308 = 0 x2 − 8x − 308 = 0
Answers
Answer:
The correct equation to solve for "x" is:
[tex]x^2+8x-308=0[/tex]
(first option in your list)
Step-by-step explanation:
Let's say that since the integers in question are separated on the number line, we can call them x, and y with for example y being the larger one (two the right of x on the number line). Since the two integers are 8 units apart, then we can write in mathematical form:
y - x = 8 (because y is the larger of the two numbers)
and solving for "y" we get:
y = x + 8
we also know that their product is 308, which we can write in the following form:
x * y = 308
Now, replacing y by "x + 8", we get:
[tex]x*y=308\\x\,(x+8)=308\\x^2+8x=308\\x^2+8x-308=0[/tex]
Therefore, the correct equation is the first one listed among your answer options.

Answers
Answer:
x = 1/8 , - 1Step-by-step explanation:
8x² + 7x - 1 = 0
Rewrite 7x as a difference
That's
8x² + 8x - x - 1 = 0
Factorize
8x( x + 1) - ( x + 1) = 0
(8x - 1)( x + 1) = 0
8x - 1 = 0 x + 1 =0
8x = 1 x = - 1
x = 1/8

Answer: (0.1) m= -4/3 y= -4/3*x+1
Step-by-step explanation:
Our equation is wriiten this way : y=mx+b where m is the slope and b a constant
let f be our function m = (f(6)-f(3))/6-3= (-7-(-3))/3 = -4/3so: y=-4/3x+bTo get b we need to replace y and x by the coordinates of a point :
(0.1) an easy one 1 = -4/3*0+b 1= b so: y= -4/3*x+1The intercepts with the y-axis are the images of 0
we can see from the table that f(0) = 1 so (0.1) is the intercept with the y-axis
Answer:
The slope is -4/3 and the equation is y=-4/3x+1
Step-by-step explanation:
The easiest way to solve these types of problems is to use Desmos. Look closely at the graph, there is a table on the left with the x and y chart list that automatically adds points onto the graph and the equation of the line. You have to determine the distance between 2 of those points. I counted from coordinate (-3,5) to (0,1) The length between those two points makes a fraction of -4/3. So -4 down and 3 across. That is how you find the slope. Then you make the equation. y=-4/3x+1

Answers
Answer:
875 cm^3
Step-by-step explanation:
Here, we want to calculate the volume of the pyramid.
To do this, we need to calculate the area of the base and then multiply this by the height of the pyramid in question
Mathematically since the base is a square, formula for the base area would be ;
L^2 = 5^2 = 125 cm ^2
Now
using the height to get the volume , we have 125 * 7 = 875 cm^3
Answer:

A city park commission received a donation of playground equipment from a parents' organization. The area of the playground needs to be 256 square yards for the children to use it safely. The playground will be rectangular. The city will pay to have soft pavement made of recycled tires installed in the playground. In the first plan, one side 8 yards longer than the other side. Which equations model the possible dimensions of the playground? x( x + 8) = 256 ( x2) - 8 = 256 x2- 8 x - 256 = 0 ( x + 4)( x - 4) = 256 x( x - 8) = 256
Answers
Answer:
x(x+8) = 256
Step-by-step explanation:
hello
one side is x
the other one is 8 yards longer, so it is x + 8
so the surface is x(x+8) = 256
hope this helps
Answer:
x(x + 8) = 256
Step-by-step explanation:
The area of a rectangle can be calculated by doing length times width.
One side is 8 yards longer than the other. Let one side be represented by x. So, another side would be x + 8.
x * (x + 8) = 256
x(x + 8) = 256
x^2 + 8x = 256

Answers
Answer:
see the first attachment for the diagramsee the second attachmentsee the third attachmentm∠BED = 135°Step-by-step explanation:
1. We have added marks to the diagram indicating that FG is a perpendicular bisector of BC. These hash marks and angle indicator are shown in the first attachment.
__
2. The proof that ∆BCE is equilateral, so all its angles are 60°, is shown in the second attachment.
__
3. The proof that m∠ECD = 30° is shown in the second attachment.
__
4. We know △ECD is isosceles because CE ≅ CD. Since the angle at C is 30°, the base angles at D and E are (180° -30°)/2 = 75°.
The angle of interest, ∠BED, is the sum of angles DEC (75°) and CDB (60°). Hence, ...
m∠BED = 75° +60° = 135°
m∠BED = 135°

Answers
Answer:
6
Step-by-step explanation:
Let's call the number of red cubes that Sam has r, and the number of yellow cubes that she has y.
Since the sum of the number of cubes is 20:
r+y=20
Since she has 8 more yellow cubes than red ones:
y=r+8
You can now plug this back into the first equation:
r+(r+8)=20
2r+8=20
2r=12
r=6
Therefore, Sam has 6 red cubes. Hope this helps!
