Answer:
Let x be one of the numbers
then since they differ by 3... Let (x-3) be the 2nd Number
Their product is 88
(x-3)x = 88
x²-3x =88
x² - 3x - 88=0
Solving The quadratic eqn
x=11 or x = -8.
To check this answer
since the Numbers are x and x-3
x= 11
x-3 = 11 - 3 = 8
(x-3)x = 8x11 = 88.
Or When x=-8
(x-3) = -8 - 3 = -11
x= -8
(x-3)x = -8 x - 11 = 88.
Have a great day!
Answer:
First Set: [11, 8], Second Set: [-8, -11]
Step-by-step explanation:
The first number will be x. The second number is x-3. So now make an equation: x(x-3)=88 because their product equals 88. So now solve.
Solving:
[tex](x)(x-3)=88[/tex]
[tex]x^{2}-3x-88=0[/tex]
Now you can factor:
[tex](x-11)(x+8)=0[/tex]
[tex]x=11, x=-8[/tex]
Now plug in each number for x for the following equation:
[tex](x)(x-3)=88[/tex]
[tex](11)(11-3)=88[/tex]
[tex]88=88[/tex]
This is true.
[tex](-8)(-8-3)=88[/tex]
[tex]88=88[/tex]
This is true.
Both are true. So now you have two sets of answers.
Your welcome!
Solve for x in the equation
Answer:
[tex] {x}^{2} + 2x + 1 = 17 \\ {x}^{2} + 2x - 16 = 0 \\ x = \frac{ - b± \sqrt{ {b}^{2} - 4ac} }{2a} \\ x = \frac{ - 2± \sqrt{68} }{2} \\ x = \frac{ - 2±2 \sqrt{17} }{2 } \\ x = - 1± \sqrt{17} [/tex]
A-container holds 6 cups of yogurt the nutrion label reads that a serving size is 1/3 cups how many servings are in the cointaner
Answer:
1/3 = 1 serving
2/3 =2 servings
1 cup= 3 servings
so if one cup is 3 servings we can multiply 3 x 6 for an answer of 18 servings

Answer:
X=50000/3 for x>0
Step-by-step explanation:
First get rid of log (3), toss it over exuation sign.
Then calculate the formula for double angle (sin 2x = sin²X + sin(X) x cos (X) + cos²X)
After you do that you should be able to divide everything with cos²X and get polynomial exuation which is solved by substitution method (you'll get tan and then switch it for lets say letter: t
If d(x) = x2 - 7x - 7, find d(x - 1).
Answer: x^2-9x+1
Step-by-step explanation:
x^2-7x-7 d(x-1)
(you would just replace x to (x-1)
(x-1)^2-7(x-1)-7
(solve by square rooting (x-1)(x-1) then foil)
x^2-9x+1

what is the probability of rolling a number that is greater than 4 on a number cube?
a.) 1/6
b.) 1/3
c.) 1/2
d.) 2/3
=========================================================
Explanation:
E = event space = {5,6}
The event space represents the set of all things we want to happen: namely rolling a 5 or a 6, since they are larger than 4.
S = sample space = {1,2,3,4,5,6}
The sample space is the set of all possible outcomes, whether we want them to happen or not. We have 6 possible outcomes.
Divide the number of items in each set
n(E) = 2
n(S) = 6
probability = n(E)/n(S) = 2/6 = 1/3
There's a 1 in 3 chance of rolling a number greater than 4.

Answer:
[tex]\overline{PO}\cong \overline{SO}[/tex]
Step-by-step explanation:
SAS (Side-Angle-Side) is a proof of congruence for two triangles. It states that when two triangles share two sides and the angle between them, they are congruent. Therefore, if PO and SO are proven to be congruent, the two triangles in the figure will share two sides and the angle between them, thus being congruent.
how do you find x in this? I need help asap!!
Answer:
Step-by-step explanation:
According to the theorem, the angle measuring 110 is one-half the measure of the arc it intercepts. That means that the major arc (this arc of which I'm speaking) measures 110 * 2 = 220.
Since the outside of a circle, regardless of how big or small the circle is, has a degree measure of 360, then x = 360 - 220 so
x = 140°

X - 3y = -13
3x + 7y = 25
Answer:
Step-by-step explanation:
x - 3y = -13
x = -13 + 3y
3 * (-13 + 3y) + 7y = 25
-39 + 9y + 7y = 25
16y = 64
y = 4
3x + 7 * 4 = 25
3x = -3
x = -1

Find the area. Round to the nearest hundredths if necessary.
Answer:
12.25π + 77, or approximately 114.48.
Step-by-step explanation:
We can divide the figure into two semicircles (which equal to one circle) and a rectangle. We know that the diameter of the circles is 7, which means the radius is 3.5. Since all points on the circle are equidistant from the center point, we can subtract 18 - 3.5 - 3.5 = 11. Therefore, the dimensions of the rectangle are 11 x 7, which means the area of the rectangle is 77. The formula for the area of a circle is πr^2. There are two semicircles, which means the sum of them both will equal one circle, since they have the same radius. The sum of the areas of the two semicircles equate to 12.25π. The area of the figure is 12.25 + 77, or approximately 114.48.

Gillian swears her computations for the
following equations prove they do not
intersect. Her brother who just finished
learning about intersecting lines told her they
definitely intersect because the slopes are
different. Gillian remembered that logic from
class and then decided she needed to be able
to prove intersection by using algebra.
Although there are multiple strategies, how
might she prove intersection without graphing
of the following equations?
4x +3y = 6 and 6x + 2y = 10
Step-by-step explanation:
Given
Two lines are [tex]4x+3y=6[/tex] and [tex]6x+2y=10[/tex]
Two lines [tex]a_1x+b_1y=c_1[/tex] and [tex]a_2x+b_2y=c_2[/tex] will intersect when
[tex]\dfrac{a_1}{a_2}\neq \dfrac{b_1}{b_2}[/tex]
for the given lines
[tex]a_1=4,a_2=6,b_1=3,b_2=2[/tex]
[tex]\therefore \dfrac{4}{6}\neq \dfrac{3}{2}\\\\\dfrac{2}{3}\neq\dfrac{3}{2}[/tex]
Hence, lines are intersecting

Rearrange so that there is no zero or negative exponent. 2m^0 n^-4
Answer:
2/n^4
Step-by-step explanation:
Anything to the zero power will become 1 so the m^0 will be 1 and that leaves just 2 in its place. Anything to a negative exponent is equal to its reciprocal so n^-1= 1/n^4. Then you multiple what remains, (2 x 1/n^4) to get the above answer.
Answer:
Step-by-step explanation:
2m^0*n^-4
=2*1*1/n^4
=2/n^4
Note:Any base that has it's power 0 is always considered as one .
If any base has negative exponent transfer that pase to the denominator then its power will be positive. For exanple:

draw and label a line a line segment a ray and an angle
Answer and Step-by-step explanation:
Everything is in the picture.
Lines are forever, so they have an arrow at each end.
Line segments have a dot at each end, so they don't go on forever.
A ray has a dot on one end and an arrow on the other, so one side goes on forever.
An angle can be acute, right, or obtuse.

find the angle r show ur work
Answer:
The measure of angle R is 112 degrees
Step-by-step explanation:
Using the given markings, we can see that we have an isosceles triangle
so RT is also 3x-2
Mathematically, the sum of the interior angles of a triangle is 180:
Thus;
9x + 4 + (3x-2) + (3x-2) = 180
9x + 3x +3x + 4-2-2 = 180
15x = 180
x = 180/15
x = 12
Recall; Angle R is 9x + 4
= 9(12) + 4 = 108 + 4 = 112
