expand and simplify 2(3a-5b +4 (a+2b)
Answer:
14a + 6b
Step-by-step explanation:
To expand use distributive property. a*(b +c) =a*b +a *c
Simplifying an expression
2*(3a - 5b + 4*(a+2b) = 2*(3a -5b + 4*a +4*2b)
= 2*(3a - 5b + 4a + 8b)
= 2* (3a + 4a - 5b + 8b)
Combine like terms. To combine like terms, add or subtract the coefficient of the variables. 3a and 4a & (-5b) and 8b are like terms
= 2*( 7a + 3b)
= 2*7a + 2*3b
= 14a + 6b
Hey there!
2(3a - 5b) + 4(a + 2b)
= 2(3a - 5b) + 4(1a + 2b)
= 2(3a) + 2(-5b) + 4(1a) + 4(2b)
= 6a - 10b + 4a + 8b
= (6a + 4a) - (10b + 8b)
= 6a + 4a - 10b + 8b
= 10a - 2b
Therefore, your answer is: 10a - 2b

On a coordinate plane, line M N goes through points (2, 3) and (negative 3, 2). Point K is at (3, negative 3). Which point could be on the line that is perpendicular to Line M N and passes through point K? (0, −12) (2, 2) (4, 8) (5, 13)
MN goes through
(2,3)(-3,2)Slope:-
m=2-3/-3-2=-1/-5=1/5Slope of perpendicular line:-
-5Passes through k(3,-3)
Equation in point slope form
y-y1=m(x-x1)y+3=-5(x-3)y+3=-5x+15y=-5x+12Check one by one
0=-5(-12)+12=60+12=722=-5(2)+12=-10+12=2Yes option B is correct
Answer:
(2, 2)
Step-by-step explanation:
First find the slope of the line MN, using the two given points:
[tex]\sf let\:(x_1,y_1)=(2,3)[/tex]
[tex]\sf let\:(x_2,y_2)=(-3,2)[/tex]
[tex]\implies \sf slope\:(m)=\dfrac{y_2-y_1}{x_2-x_1}=\dfrac{2-3}{-3-2}=\dfrac15[/tex]
If two lines are perpendicular to each other, the product of their slopes will be -1.
Therefore, the slope (m) of the line perpendicular to MN is:
[tex]\implies \dfrac15 \times m=-1[/tex]
[tex]\implies m=-5[/tex]
Using the point-slope form of the linear equation with point K (3, -3), we can construct the linear equation of the line perpendicular to MN:
[tex]\sf y-y_1=m(x-x_1)[/tex]
[tex]\implies \sf y-(-3)=-5(x-3)[/tex]
[tex]\implies \sf y=-5x+12[/tex]
Now we have the equation of the line perpendicular to MN, we can input the x-values of the solution options to see which once is correct:
[tex]x=0\implies \sf y=-5(0)+12=12\implies (0,12)[/tex]
[tex]x=2\implies \sf y=-5(2)+12=2\implies (2,2)[/tex]
[tex]x=4\implies \sf y=-5(4)+12=12\implies (4,-8)[/tex]
[tex]x=5\implies \sf y=-5(5)+12=-13\implies (5,-13)[/tex]
Therefore, the point that is on the line that is perpendicular to MN and passes through point K is (2, 2)
The probability that juliana will take a particular type of dance class is shown in the chart below. She will definitely take either ballet or jazz, but not both. The probability that she will take jazz on wednesday night is 27%. If the probability that she will take ballet is 70%, what is the probability that she will take jazz on saturday morning?.
The probability that Juliana will take jazz on Saturday morning based on the decision tree given is 3%.
What is the probability that jazz is taken on Saturday morning?The probability that jazz is taken is:
= 1 - Probability of ballet
= 1 - 70%
= 30%
The probability that if jazz is taken, it will be taken on Wednesday is:
= Probability that jazz is taken on Wednesday night / Probability that Jazz is taken
= 27% / 30%
= 90%
The probability that Jazz is taken on Saturday morning is therefore:
= Probability that jazz is taken x (1 - Probability of Wednesday night)
= 0.3 x ( 1 - 90%)

"What do milkweed bugs eat"

Answer: what do milky buggies munch on UWU
Step-by-step explanation:
X^2 +8x+7
What is the vertex?
(X= -b/2a)
What is the Y intercept?
Step-by-step explanation:
any quadratic equation has the form
y = ax² + bx + c
so, we can see in our case
a = 1
b = 8
c = 7
the x value of the vertex is indeed camcorders by
x = -b/(2a) = -8/2 = -4
the corresponding y we get then
y = (-4)² + 8×-4 + 7 = 16 - 32 + 7 = -9
the vertex = (-4, -9).
the y- intercept is simply the point with x = 0 (and the corresponding y value).
which is c, because
y = 0² + 8×0 + 7 = 7
the y-intercept = (0, 7)
Which polynomials are prime? check all of the boxes that apply. x2 9 x2 – 9 x2 3x 9 –2x2 8
Prime polynomials cannot be factorized in smaller degree polynomials. The prime polynomials out of the considered option are:
Option 1: x^2 + 9Option 3: x^2 + 3x + 9What are prime polynomials?Those polynomials with integer coefficients that cannot be factored further, with factors of lower degree and integer coefficients are called prime polynomial.
(it is necessary that no factors exists having their coefficients are still integers and they're of lower degree)
Checking all the options for them being prime or not:
Option 1: [tex]x^2 + 9[/tex]Take [tex](x+a)(x+b) = x^2 + 9[/tex]
Then, expanding it gives:
[tex]x^2 + (a+b)x + ab = x^2 + 9 \implies a+b = 0, ab = 9[/tex]
or we get: [tex]a = -b, ab = -b^2 = 9, b^2 = -9[/tex]
Square of a real number doesn't exist, so this factor doesn't exist. Thus, it is prime polynomial.
Option 2: [tex]x^2 - 9[/tex]We have the identity [tex](a+b)(a-b) = a^2 - b^2[/tex]
and since 9 is square of 3, therefore, we get:
[tex]x^2 -9 = x^2 -3^2 = (x+3)(x-3)[/tex]
So it got factorized. Thus, not a prime polynomial.
Option 3: [tex]x^2 +3x + 9[/tex]Take [tex](x+a)(x+b) = x^2 + 3x + 9[/tex]
Then, expanding it gives:
[tex]x^2 + (a+b)x + ab = x^2 + 3x + 9 \implies a+b = 3, ab = 9[/tex]
That gives:
[tex]a = 3-b\\ab = b(3-b) = 3b - b^2 = 9\\b^2 -3b + 9 = 0[/tex]
Solving this quadratic equation by root formula gives:
[tex]b = \dfrac{-(-3) \pm \sqrt{(-3)^2 -4(1)(9)} }{2}\\\\b = \dfrac{-(-3) \pm \sqrt{-27} }{2}\\[/tex]
this makes 'b' a complex number and it doesn't remain a real number as its expression contains square root of a negative number.
Thus, this polynomial cannot be factorized in terms of smaller degree polynomials. Thus, its a prime polynomial.
Option 4: [tex]-2x^2 + 8[/tex]Taking -2 common out, we get:
[tex]-2(x^2 - 4) = -2(x^2 - 2^2) = -2(x-2)(x+2)[/tex]
Thus, it got factorized, and therefore not a prime polynomial.

One sector has an area of 167 square inches and an arc measure of 110°.
The area of the circle that contains the sector is 546.5 in² (rounded to the nearest tenth)
Calculating area of a circleFrom the question, we are to determine the area of the circle.
The area of a circle can be determined by using the formula,
[tex]A = \pi r^{2}[/tex]
From the given information,
Area of the sector = 167 in²
Arc measure = 110°
Using the formula,
[tex]Area\ of\ sector = \frac{\theta}{360 ^\circ} \times \pi r^{2}[/tex]

Next, we have to use the alt. int. angles are congruent theorem, so we can say that angle QTR and angle SOT are congruent due to this rule.
Next we have to use reflexive property, and the only thing that fits is the transversal intersecting the parallel lines. So we can say that QT is congruent to TQ.
Then we can say that triangle SQT and triangle ROT are congruent due to SAS.
Finally, we can say angle QTS is congruent to angle TQR because of corresp. parts of congruent triangles are congruent(CPCTC for short)

of the sofa is $1,029. A customer can get an additional 5% discount off the sale price for paying with cash. At
checkout, a 6.5% sales tax on the final price is added to the cost of the sofa. What is the total cost of the sofa,
including sales tax, for a customer paying with cash?
Answer:
$694.06
Step-by-step explanation:
OG price= 1,029
discount=.05
sales tax =.065
1/3(og price)=1/3(1029)=343
one third of $1,029 is 343, hence we take off $343 from the orginial price
1029-343= $686--> sales price
.05*salesprice= .05*686=34.3
subtract 5% discount: 686-34.3= $651.71
