Five minus two times y equals fourteen

Mathematics
1 answer:
podryga [215]3 years ago
6 0

Answer:

y=-\frac{9}{2}

Step-by-step explanation:

Solve by isolating the variable on one side of the equation:

5-2*y=14

Simplify -2*y to -2y:

5-2y=14

Subtract 5 from both sides:

-2y=9

Divide both sides by -2:

y=-\frac{9}{2}

Given the hyperbola y = 1/x, find the area under the curve between x = 5 and x = 33 to 3 sig. dig. namely: integral subscript 5
Shtirlitz [24]

Answer:

(b) ln(33/5)

Step-by-step explanation:

\int\limits_{5}^{33}  \frac{1}{x} \, dx = \ln(x)  \Big|\limits_{5}^{33} = \ln(33) - \ln(5) \\\\= ln(33/5)

Remember that  in general

\ln(a) - \ln(b) = \ln(a/b)

In XYZ, mX=90 and mY=30.In TUV,mU= 30 and mV=60. Which is true about the two triangles? XYZ=TUV, XYZ= VUT,No congruency statemen
Flauer [41]

Answer:

No congruency statement can be made because the side length are unknown.

Step-by-step explanation:

The sum of the measures of all interior angles in a triangle is always 180°.

In triangle XYZ,

m\angle X=90^{\circ}\\ \\m\angle Y=30^{\circ},

then

m\angle X+m\angle Y+m\angle Z=180^{\circ}\Rightarrow m\angle Z=180^{\circ}-90^{\circ}-30^{\circ}=60^{\circ}

In triangle TUV,

m\angle U=30^{\circ}\\\\m\angle V=60^{\circ},

then

m\angle T+m\angle U+m\angle V=180^{\circ}\Rightarrow m\angle T=180^{\circ}-30^{\circ}-60^{\circ}=90^{\circ}

We have two triangles with congruent angles but we have no information about side lengths. Therefore, can not be made because the side length are unknown. Correct option is last option.
