Which of the following is equivalent to 2(x – 5) <3(4 – 2x)?

Ksenya-84 [330]

Answer:

4th one

2x-10<12-6x

Step-by-step explanation:

2(x-5)=2x-10

3(4-2x)=12-6x

So: 2(x-5)<3(4-2x) is

2x-10<12-6x

I really need help I’ve worked it out already though

Vikki [24]

<h2>Answer:</h2><h3>75(5r)+75(3d)+75(4f)</h3>

Solution,

Cost of roses in 1 bouquet=5r

Cost of daisies in 1 bouquet=3d

cost of green filler in 1 bouquet=4f

Total no. of bouquet=75

cost of one bouquet=5r+3d+4f

total=75(5r+3d+4f)

 =75(5r)+75(3d)+75(4f)

hope it helps

70 POINTSS!!!! URGETT PLS HELP!! Vectors t = −5i + 2j, u = −3i + 7j, and v = 8i + 20j are given.

LUCKY_DIMON [66]

The angle between the vectors t and u is 45°. And the vector t and vector w are orthogonal to each other.

<h3>What is a vector?</h3>

The quantity which has magnitude, direction and follows the law of vector addition is called a vector.

The vectors are given below.

t = −5i + 2j, u = −3i + 7j, and v = 8i + 20j

Part A: Then the angle between vectors t and u will be

$\cos \theta = \dfrac{\overrightarrow{a} \cdot \overrightarrow{b}}{|\overrightarrow{a}| + |\overrightarrow{b}|}$

Then we have

cos θ = [(−5i + 2j)(−3i + 7j)] / [√{(-5²) + 2²} + √{(-3)² + 7²}]

cos θ = 1 / √2

θ = 45°

Part B: c is a scalar

If $\rm \overrightarrow{\rm v} = (a, b)$ , then $\rm c\overrightarrow{\rm v} = c(ca, cb)$

Let c = 2, then we have

$\overrightarrow{\rm w} = c\overrightarrow{v}\\\\\overrightarrow{\rm w} = (2*8, 2*20)\\\\\overrightarrow{\rm w} = (16, 40)$

Part C: Use the dot product to determine if t and w are parallel or orthogonal.

$\overrightarrow{\rm t} \cdot \overrightarrow{\rm w} = (-5, 2)(16, 40)\\\\ \overrightarrow{\rm t} \cdot \overrightarrow{\rm w} = -5*16+ 2*40\\\\ \overrightarrow{\rm t} \cdot \overrightarrow{\rm w} = -80+ 80\\\\ \overrightarrow{\rm t} \cdot \overrightarrow{\rm w} = 0$

More about the vector link is given below.
