Answer:

The answer to number 3 would be 6 on the number line, open circle, and then a line dashed to 42, and 4 on the number line, closed circle, and a closed line to 7.

The answer to number 4 would be -8 on the number line, open circle, and then a line dashed to 2, and 9, open circle closed line to 81.

What is the value of s? 0.7(3s+4)−1.1s=7.9

Alina [70]

2.1s+2.8-1.1s=7.9 Distribute the 0.7 in the parenthesis

s+2.8=7.9 Combine like terms which in this case is 2.1s and -1.1s

s=5.1 Subtract 2.8 from both sides.

.Write the quadratic equation in standard form that has x-intercepts at (-4/3,0) and (-3,0)

Vladimir79 [104]

Answer:

y = a(x² + (13/3)x + 12/3)

Step-by-step explanation:

First use the equation in x-intercept form: y = a(x-r)(x-s)

Where r and s are the values for the x-intercept

Substitute the x-intercepts

y = a(x - (-4/3)) (x - (-3))

Simplify

y = a(x + (4/3)) (x + 3)

Distributive property for brackets:

y = a(x² + 3x + (4/3)x + 12/3)

Find common denominator in fractions to collect like terms

y = a(x² + (9/3)x + (4/3)x + 12/3)

y = a(x² + (13/3)x + 12/3)

We cannot solve for the "a" value without another point.

If given the other point, substitute it for x and y to solve for a.

Then rewrite the equation with the "a" value.

Question 11

1) $\overline{BA} \cong \overline{FA}$ , $\angle 1 \cong \angle 2$ (given)

2) $\angle A \cong \angle A$ (reflexive property)

3) $\triangle AEB \cong \triangle ACF$ (ASA)

4) $\overline{AC} \cong \overline{AE}$ (CPCTC)

Question 12

1) Isosceles $\triangle ACD$ with $\overline{AC} \cong \overline{AD}$ , $\overline{BC} \cong \overline{ED}$ (given)

2) $\angle ACD \cong \angle ADC$ (angles opposite congruent sides in a triangle are congruent)

3) $\angle ACB$ and $\angle ACD$ are supplementary. $\angle ADC$ and $\angle ADE$ are supplementary (angles that form a linear pair are supplementary)
