Multiply 4x(-3x - 5)

2 answers:

6 0

Using the distributive property the product is -12x-20. To distribute you take the numbers and or variables outside of the paranthesis and multiply it by each one in the parenthesis such that 4x is multiplied by -3x getting -12x and multiplying 4x by -5 and the product is -20x and all together the answer is -12x-20

To solve this you distribute. Si multiply 4x and -3x to get -12x^2. Then multiply 4x and -5 to get -20x. Put those to answers together to get your final answer which is -12x^2-20x.

Answer:

Step-by-step explanation:

The diagram shows the rectangle with vertices at A(3,4), B(3,7), C(4,7) and D(4,4).

1. Rotate rectangle ABCD by 180° about the point (3,4) (vertex A). This rotation has the rule:

$(x,y)\rightarrow (6-x,8-y)$

So, the image points have the coordinates A'(3,4), B'(3,1), C'(2,1) and D'(2,4)

2. Dilate by a scale factor of 2 with the center of dilation at origin. This dilation has the rule:

$(x,y)\rightarrow (2x,2y)$

So, the image points have the coordinates A''(6,8), B''(6,2), C''(4,2) and D''(4,8)

3. Reflect it over the y-axis. This reflection has the rule:

$(x,y)\rightarrow (-x,y)$

So, the image points have the coordinates A'''(-6,8), B'''(-6,2), C'''(-4,2) and D'''(-4,8) that are exactly the coordinates of the second rectangle shown.

Thus, correct option is option D.

Can someone help me out with this, i have to turn it in tomorrow

Answer:

Q = 132

P = 48

Step-by-step explanation:

Angles R + S = 180, which means

(5x + 3) + (14x + 6) = 180

19x + 9 = 180

19x = 171

x = 9

R = 5x + 3 = 5(9) + 3 = 48

S = 14x + 6 = 14(9) + 6 = 132

Q = 180 - R = 180 - 48 = 132

P = 180 - Q = 180 - 132 = 48

Can someone teach me how to do this im a good learner i just missed days

mrs_skeptik [129]

I’m not very good at explaining but if we explain from the beginning the equation is y=m(x)+b and m means the slope while b means y- intercept so all you have to do is substitute these variables with the numbers in the problem basically it would be y=10x+10 also the picture attached is how you graph it. Hope this helped:)

There were 292 tickets sold for a high school basketball game. An adult ticket cost $3. A student ticket cost $1. Ticket sales w

Best way to start this is set up your ground work...
Adult= A Student =S

A + S = 292

A3 + S1 = 470$

this will be your system of equations now set up your matrix and have A or S at the bottom stand alone.
