So, this is how we do it O w Ox = −1;y = 3x+1Step: Solve x = −1 for x:Step: Substitute −1 for x in y = 3x+1:y = 3x+1y = (3)(−1)+1y = −2(Simplify both sides of the equation)Answer:x=−1 and y=−2
Hope I helped! :3

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.

A recipe for tropical punch calls for 2 22 cups of pineapple juice and 3 33 cups of orange juice. Jo creates a drink by mixing 3

Murrr4er [49]

Situation 1: Recipe for tropical punch

Number of cups of pineapple juice = 2.

Number of cups of orange juice = 3.

Total number of cub of juice = 2+3 = 5 cups.

Let us find % of pineapple and orange juice in total number of cups of juice.

% of pineapple = 2/5 = 0.40 = 40%.

% of orange juice = 3/5 = 0.60 = 60%.

Situation 2: Jo's drink

Number of cups of pineapple juice = 3.

Number of cups of orange juice = 4.

Total number of cub of juice = 3+4 = 7 cups.

Let us find % of pineapple and orange juice in total number of cups of juice.

% of pineapple = 3/7 = 0.429 = 42.9%.

% of orange juice = 4/7 = 0.0.571 = 57.1%.

Please note: In Jo's drink pineapple juice % increased and orange juice % decreased by the tropical punch recipe.

<h3>Therefore, Jo's drink will have a stronger pineapple taste.</h3>
