A function has a discriminant of 25.
How many x-intercepts does it have?
Answer:
2
Step-by-step explanation:
If the value of the discriminant is positive, there are two real solutions for x, meaning the graph of the solution has two distinct x-intercepts
Here 25 is positive discriminant, hence the function will have 2 x - intercepts
16. A toy car travels at a constant rate of 11 inches every
5 seconds. At this rate, which of the following is closest
to the number of feet the car travels in 2 minutes ?
F. 5
G. 13
H. 22
J. 24
K. 28
Answer:
5
Step-by-step explanation:
first you do 11 divided by 5
then you multiply it by 2
which gives you 4.4
the closest number is 5
correct me if i am wrong
Answer:
H. 22
Step-by-step explanation:
- The car travels 11 inches every 5 seconds, so in one second it travels:
11 inches / 5 seconds = 2.2 inches/second
- In 2 minutes (120 seconds), the car travels:
2.2 inches/second * 120 seconds = 264 inches
- To convert inches to feet, we can divide by the number of inches in a foot:
264 inches / 12 inches/foot = 22 feet

10x + 8 = 3(x – 2)
10x + 8 = 3x ___
7x = ___
x = -2
A: 10x + 8 = 3(x – 2)
10x + 8 = 3x – 6
7x = – 14
x = -2
Step 1 : Multiplying 3 with -2, we get -6
Step 2 : Subtract -6 and 8 , we get -14
Step 3 : We get x = -2
What is an equation?"An equation is a formula that expresses the equality of two expressions, by connecting them with the equal sign. Solving an equation containing variable consists of determining which values of the variables make the equality true."
Given equation
10x + 8 = 3(x – 2)
In this step by multiplying 3 with -2, we get -6
10x + 8 = 3x - 6
Subtract the variables
Subtract -6 and 8 , we get -14
7x = -6 - 8
7x = -14
Divide with 7 on both sides, we get
x = -2
Hence these are the following steps to get x = -2
Step 1 : Multiplying 3 with -2, we get -6
Step 2 : Subtract -6 and 8 , we get -14
Step 3 : We get x = -2

Help me please
Answer:
90
Step-by-step explanation:
If there is a straight line and 1 angle is 90 degrees, the angle next to it is also 90 degrees.
Answer:
x = 90°
Step-by-step explanation:
Since x and 90° share the same straight line, they are supplementary, meaning they must add up to 180°. Hence x must be 180-90 = 90.

What is being constructed based on the markings in the following diagram?
Line AB with two points C and D on each side of the line; a circle is created with center C passing through point D, and the intersection of circle C with line AB creates points E and F such that point A is between points E and F and point F is between points A and B. Point G is not located on line AB and is on the same side as point D. A circle is created with center F and a radius of FG, and another circle is created with the same radius from point E. Points H and I are intersecting points of circles E and F, and a line is drawn through points H and I.
Inscribed regular hexagon
Inscribed equilateral triangle
Perpendicular line through a point off a line
Perpendicular line through a point on a line
Answer:
The correct option is;
Perpendicular line through a point off a line
Step-by-step explanation:
Based on the markings in the diagram, we have;
Marking points E and F along AB extended forms two points equidistant from the point C on the line AB
Construction of the line HI by using equal arc lengths from E and F creates two points equidistant from E and F on either side of the line AB such that HI passes through C forming a perpendicular bisector from C to AB.
Therefore, a perpendicular line has been constructed from the point C off the line AB to the line AB
Hence the correct option is the construction of a perpendicular line through a point off a line.

When dividing complex numbers, why do you need to multiply the numerator and denominator by the complex conjugate of the denominator?
Answer:
Step-by-step explanation:
So that the denominator is a real number. I know that doesn't sound like a good reason, but it is the reason mostly by convention. You don't want complex i's floating all over the answer. There should be just one i.
Answer:
You have to multiply by the complex conjugate because the denominator has to be a real number. By multiplying the complex conjugate you can transform the denominator in to a real number.

Solve for X (BRAINLIEST)
Answer:
x = 24
Step-by-step explanation:
The triangles are similar so we can use ratios to solve
x 6
------ = -----------
x+8 8
Using cross products
8x = 6*(x+8)
8x = 6x+48
Subtract 6x from each side
8x-6x = 48
2x = 48
Divide by 2
2x/2 = 48/2
x = 24
Answer:
x = 24
Step-by-step explanation:
Very similar to the previous problems of this type, these two triangles have a shared angle A and both have a right angle, prove AA similarity.
From there, we can set up a ratio:
(x+8)/x = 8/6
Multiply both sides by x:
x+8 = 8x/6
Multiply both sides by 6:
6x+48 = 8x
Move the 6x to the right:
48 = 2x
Divide both sides by 2:
x = 24

Write the equation of a line that passes through (-5,6) and has a slope of 4, please!
Answer:
y = 4x + 26
Step-by-step explanation:
There are lots of different methods to do these types of questions, but this is the way i like to do it.
Coordinate (x1, y1) : (-5, 6) and Gradient (m): 4
Start with this generic equation:
y- y1 = m(x-x1)
Substitute in the values they have given you:
y - 6 = 4(x-(-5))
This becomes:
y - 6 = 4 (x+5)
y - 6 = 4x + 20
Keep solving by moving the 6 over to the other side:
y = 4x + 20 + 6
y = 4x + 26
An easy way to double check:
1) the coefficient of x is the slope. We got 4x, and the slope is 4, so that's correct.
2) Substitute x=-5 into the equation, and we get 6, which is the exact coordinate that they gave us. This is also right.

Answer: A
Step-by-step explanation:
6x + 12x + 90 = 180
18x + 90 = 180
-90 -90
18x =90
x= 5
6(5) + 12(5) + 90 = 180
30 + 60 + 80 = 180
180= 180 It makes sense that it is A because there is one right angle which has a measure of 90 degrees and the other one have two measures 6x and 12x and both of them have to also equal 90 degrees. So 90 pluse 6x plus 12x has to equal 180 because they all lie on a straight line and a straight line has an angle measure of 180 degrees.

A scientist is running an experiment with
two species of bacteria that grow exponentially.
If species A doubles in population every
two days, species B doubles in population
every five days, and each species began the
experiment with a population of 50 bacteria,
what will the difference be between the
populations of the two species after ten days?
(A) 200
(B) 800
(C) 1,200
(D) 1,400
Answer:
D 1,400
Step-by-step explanation:
Species A doubles every 2 days and species B doubles every 5 days, so in 10 days, species A will double 10/2 = 5 times and species B will double 10/5=2 times. After 10 days from an initial population of 50 in each species, species A will have 50 x 2 ^5= 50 x 32 = 1,600 population while species B will have 50 x 2 ^2 = 200 population. Their difference is 1,600-200 = 1,400.
